We often hear that we are living in an ‘age of information’. At any given moment, we have access to all of humanity’s collective knowledge at the palm of our hands and it is information that allows our species to move forward.
This information comes to us from all kinds of places. Be it the internet or the many different research facilities all around the world striving to gather new knowledge and insights into things we don’t know about.
But did you know that one source of information is the past itself? No, not the past we have been through as a species but the past way beyond that, even billions of years.
This is not some crazy theory, it is the truth. In fact, a lot of our understanding of the universe has been possible because we can look at its past.
So, how is it that we can look into the past of the universe? ‘Doesn’t that violate some kind of laws of physics or something?”, you might ask. Well, no. It’s because of the laws of physics that this is possible, actually.
So, lets talk light. We know that the fastest thing in the universe is light. It can travel at a speed of 299,792,458 metres per second. That’s insanely fast. But the universe is so unimaginably vast, that on that scale, even the speed of light seems like that of a tortoise.
Also, light can travel forever in the vacuum of space (if it doesn’t hit anything along the way). Combining this fact, with the size of the universe, pretty much explains how we can see into the past of our universe.
The light created at one point in time and space, can literally travel for billions of years before hitting the eyes of an observer. To the observer, it would be like seeing in the past billions of years ago.
If you are still confused, let me explain by taking an example of our own sun. We know that our sun is 150 million kilometres away from us. Light covers this distance in about 8 minutes and 20 seconds.
So, what that means is that we are looking 8 minutes and 20 seconds into the past of the sun because it is light that enables us to ‘see’ the state of anything. So, if the sun were to suddenly disappear, we wouldn’t even notice it for 8 minutes!
The same is true for more distant galaxies and the billions of suns in them. Everyday, light reaches Earth from trillions of stars in the universe. Some of that light is millions of light years old and some is billions of years old. In many cases, the stars are long gone and we won’t notice it for billions of years!
When we are staring at the night sky, a lot of the stars that we see aren’t even there. What we see as stars are mere images of the stars past, a ghostly presence, trying to tell the tale of what once was. In a way, we are getting messages from the past, all the time.
Mercury’s orbit brings it as close as 43 million kilometers to as far as 70 million kilometers from the sun. At the closest point in its orbit the sun looks three times bigger than it does from Earth. Mercury orbits around the sun in just 88 days, traveling an average of 50 km a second. A day on Mercury lasts about 55 Earth days.
Mercury has no atmosphere, however, it does have an exosphere. The exosphere is built of atoms blasted off its surface from solar wind. Mercury looks like Earth’s moon. There isn’t an atmosphere capable of breaking up impactors before they hit the surface. Mercury also has many cliffs and smooth areas, formed as the core was cooling. When the core cools it tends to contract, breaking apart the surface by pulling it in slightly.
Without an atmosphere the surface temperature varies wildly, from -173 Celsius to 472 Celsius. With each day lasting 59 of Earth’s, the side facing the sun is blasted non-stop while the side facing away is left to stay extremely cold and radiate away what’s left of its heat.
Mercury is the second densest planet, after Earth. The gravity on Mercury is a lot lower than Earth. Acceleration due to gravity on Earth is about 9.8 m/s^2 while the acceleration on mercury is only about 3.6 m/s^2. Everything on Mercury would weigh about 1/3 as much as it does on Earth.
Mercury has a magnetic field, although it is very weak. Its strength is only about 1.1% that of Earth’s. It is a global field that is dipolar. Once it may have been as strong, or even stronger than Earth’s. The field most likely weakened as the core cooled and could no longer rotate.
It is possible to see Mercury with the naked eye. Mercury was first mentioned by Sumerians, and later recorded by the Babylonians. Mercury even crosses in front of the sun about 13 times a century, which was even watched live by many people over the internet in 2004.
In 1966 Soviet scientists shot radio waves at Mercury to determine if it rotated. They found that the length of its day was equivalent to about 59 of Earth’s.
Later, in 1974, NASA decided to study Mercury and sent the Mariner 10 spacecraft there. Mariner 10 made a total of three flybys. The goal was to measure the magnetic field, take pictures, and to test if it had an atmosphere.
Finally the messenger probe was launched august 3rd 2004, attaining orbit on march 18th, 2011. Messenger helped make many important discoveries. One of the most important is that many volatile elements exist on Mercury, including: Potassium, sulfur, sodium, and chlorine. Another important discovery is that Mercury has ice. This ice exists on the poles, and only in the shadows. This can happen because Mercury has no atmosphere to regulate temperature, so it’s a lot cooler in the shadows. A good thing about poles is that some spots are always in shadow, allowing water deposited there to freeze and stay there.
One of the most fundamental symmetry of nature, the CPT symmetry, is trying to be falsified for years by high-energy physicists. And today… it is still valid!
In this post, I will discuss the C, P and T transformations, and the definition of the resulting CPT symmetry and why we are trying to falsify it.
Antimatter experiments are very exciting as they aim to measure the properties of the antimatter particles, and thus verify that the observations match those of the corresponding matter particles (up to sometimes a global minus sign). This consists of a deep test of the CPT theorem, one of the most fundamental symmetries of nature.
I will not speak about the news of last December, where the antihydrogen energy spectrum was precisely measured at CERN by the ALPHA experiment (see here for the official announcement]). The reason is that this is an old news that has been widely covered on Steemit by at least three authors (I may have forgotten some, apologies in advance and please let me know in the comments): @dragosroua (see here), @krnel (see here), and @daianynascimento (see here).
I will instead move on with recent BASE measurements and use them as a good excuse to write in details on the CPT symmetry.
Before starting, I will recap a few things about the concepts of elementary particles and antiparticles.
In a very old post of mine, written at the time I just joined Steemit, I have browsed the landscape of the Standard Model of particle physics, describing the elementary particles that are the building blocks of nature and the way they interact with each other through three out of the four fundamental forces. Moreover, for details on the Higgs boson (although this is not related to what I will talk about today), see my two posts on the topic here and there).
Each of these particles is always associated with an antiparticle. We hence have quarks and antiquarks, electrons and positrons, muons and antimuons, and so on. But what are the differences between a particle and an antiparticle?
They are actually very few differences. Particle physics relies on quantum field theory, where the basic objects are quantum fields. A particle and a corresponding antiparticle can be seen as excitations of a given field. Skipping all nasty details, the important point is that particles and antiparticles are connected to the same object. Which means, they must have similar properties and exhibit very few differences.
And what I said in the above section is exactly what is going on. Particles and antiparticles are entities that have very few differences.
They are characterized by their mass, their width (or give or take, their lifetime), and their electric charge (or any other quantum number if we want to use nice words and be precise). Moreover, if we compare all the properties of a given particle and the corresponding antiparticle, they will be the same up to the quantum numbers that will be opposite. A particle and an antiparticle will have an opposite electric charge, for instance.
In addition (and now this is actually the important point), when we build the way particles and antiparticles will interact, we actually design a mathematical function of the various fields of the model. This function (also known as a Lagrangian to use another nice word) embeds how every single particle will interact with any other particles.
This function is however not random, and there are constraints on how it should be constructed. The Lagrangian must satisfy some symmetries. This ranges from the symmetries connected to the fundamental interactions to the famous CPT symmetry. I will focus on the latter, the CPT symmetry.
The CPT symmetry is an acronym standing for charge, parity and time-reversal symmetry. What does it mean? Let us consider a given reaction involving a bunch of particles.
The P transformation means that the spatial configuration of the particles is reversed. It can be seen as a mirror transformation: we put the reaction in front of a mirror so that everything is flipped (left becomes right, for instance). I illustrate this one with the image on the right for clarity.
There are fundamental reasons that nature is CPT symmetric, or that le laws of nature are equivalently invariant under a joint C, P and T transformation. This can be demonstrated within the quantum fied theory framework.
We mention the CPT symmetry, but one may ask to ourselves, why not having P, C or T conserved individually and being good symmetries of nature? Because of data! There exist concrete examples showing that the three individual transformations are not symmetries of nature. This was actually not always believed to be like that.
A beta decay is not invariant under a P transformation, as observed in 1957 by C.S. Wu and collaborators. The electrons arising from such a decay have a preferred direction opposite to the spin projection. In the case of a P symmetry, one would observe both the reaction and its mirror image equally. This is not the case.
From then, physicists were believing that CP was a correct symmetry of nature. C and P were thought to be both violated, but the two violations were canceling each other. But what is a CP transformation more precisely?
Let us take an electron moving with a velocity v. Through a mirror transformation, we get an electron moving with a velocity -v. Then, if we replace an electron by a positron (the C transformation), we get a positron moving with a velocity -v. This means that a CP transformation gives us the mirror image of the associated antimatter particle. This is illustrated in the picture on the left by the horizontal lines.
In 1964, V. Fitch and J. Cronin (and collaborators) observed that the CP symmetry was violated in the decays of some particles called kaons. The CP transformation is thus not a symmetry of nature, as T (since CPT cannot be violated). The amount of CP violation is thus compensated by the amount of T violation. And all of this is fully accommodated in the Standard Model.
Since the CPT symmetry seems to be a symmetry of nature, physicists are trying to falsify it for decades. Equivalently, this means to verify this assumption to the deepest level.
The BASE collaboration at CERN is aiming to measure the magnetic moment of the antiproton, and a comparison with proton data will provide a sensitive test of the CPT invariance.
Just for fun, ‘BASE’ is an acronym standing for the Baryon Antibaryon Symmetry Experiment.
BASE has reported last week the most precise measurement ever made of the antiproton magnetic moment. It has been shown that the proton and antiproton moments are identical, apart from their opposite signs, within an error of 0.8 parts in a million. That is precision! This sign difference is exactly the only difference predicted by the CPT symmetry.
To make a long story short, the BASE experiment uses the slowed down (and cooled down) antiprotons produced at CERN. It then studies their behavior within a magnetic field, once antiprotons are trapped within a magnetic container.
The next step is to improve the precision by a factor of 200 to 800 in a rather close future, thanks to a new antiproton trapping technique.
In this post, I detailed what is the CPT fundamental symmetry of nature, and also what the C, P and T transformations meant. This brought me to touch the concept of matter and antimatter and the tests physicists are making to unravel matter-antimatter difference.
The BASE experiment is one of the experiments that are trying to falsify the CPT invariance of nature. It relies on measuring the antiproton magnetic moment with an extreme precision, and to compare the results with the proton data.
For the moment, nothing seems to show that the CPT symmetry does not hold.
Many wrongly assume that Tesla had some secret. He didn't. And he wrote about his ideas very specifically but in a way that many people, for some reason, overlook. In this short post I will give you the key to understanding his work and from there I will show you what he wrote and how he wrote it.
This 'secret' is explained in the following articles and lectures:
In these articles Tesla tells about the ether, which was considered to be a homogeneous fluid filling up all space. And it was assumed that this also was the primary cause of electricity. But that can not be the case, according to Tesla, for electricity is caused by a gaseous medium (which he often refers to as
the medium instead of
the ether) which is also filling up all space but has very different properties.
The ether can not be compressed, but
the medium can be compressed, just like any other gas. It has a volume (capacitance), a quantity (charge), a pressure (voltage) and most importantly, it has a property that no-one seems to ever consider, it has a temperature. It, or electricity, largely follows the laws that apply to all gasses, with some extras because of the electrostatic attraction and repulsion and induced magnetic effects.
Electricity is a gas
When you compress a gas, it gives off its heat to the surroundings, and when you suddenly expand it -such as in an airco or fridge- it cools. Exactly the same goes for electricity and it can be shown with IR-thermometers.
The voltage (pressure) can be increased by decreasing the volume (same charge in a smaller capacitance), increasing the quantity (more charge) or by raising the temperature! As crazy as this all sounds, it is actually true and it gives most elegant explanations for many known phenomena, as I will show in future posts.
In Tesla's high voltage experiments his aim was to create an as high as possible pressure in order to create an as rapid as possible expansion (=discharge resulting in cooling).
This too I will show in future posts. For now, just let the idea sink in that electricity is caused by a gaseous medium, and I promise it will all become clear....

An aircraft flying at super sonic speeds create sonic booms and light that leave behind it. Now scientists have made the ultrafast camera that can captures these ultra sonic lights. The scientists believe that the technology used behind it can be used help them to observe neurons fire and live activities in the brain.
How Sonic Booms are created? Object moving in the air pushes the air in its way thus creating waves that move with the speed of sound in all directions. When a object moves with a speed of sound or greater than the speed of sound it can leave behind the pressure waves and these waves keep on piling upon one another providing us new waves known as Sonic Booms. These sonic booms produced are confined in a conical region also known as Mach Cones
Light travels at a speed of 300,000 km/s when it travels through vacuum and according to Albert Einstein, nothing can travel faster than speed of light but however the light can itself decrease its velocity when it travels through different medium. e.g When light travels through water it travels with a speed of 60% of its max value. This study has helped scientists to generate Super Sonic cones or Mach Cones. Scientists experimented it at very low scale and found surprising results with elusive scattering of light.
In order to capture this scattering of light, researchers developed a camera that can capture images at 100 billion Frames Per Second. The camera basically uses two things one to capture the images and the other one is to store the temporal information that would help scientists to reconstruct the event frame by frame.
The speciality about this camera is that it can capture a huge amount of information even in a single exposure. It is very helpful in analysing the unique and random events. According to some great scientists this camera have its great uses in biomedical industry to have a deep study of tissues, blood flow and even movements of neurons. This amazing camera can greatly help scientists to really know about how actually the brain works. The possibilities are limitless with this great tech.

Have you ever sneezed when looking at the sun? Roughly 25 % of the human population has a condition that is known as Autosomal dominant Compelling Helio-Ophthalmic Outburst (shortened ACHOO) or the photic sneeze reflex, which basically means that the people with this condition have problems controlling their sneezing when looking at bright lights like the sun or directly into a light bulb.
I have this condition, and it is not really bothersome at all. I get the occasional sneeze when it’s very sunny outside and I’m looking at the direction of the sun, but in everyday-life this is definitely not a problem. It is inherited from your genes, so considering both my girlfriend and I have it, I am pretty sure I can expect my son to have it as well.
The sun, responsible for lots of sneezes in people with the dominant Compelling Helio-Ophthalmic Outburst. Image by Lykaestria at the English language Wikipedia, posted with the Creative Commons Attribution-Share Alike 3.0 Unported license.
The condition have been linked to a single-nucleotide polymorphism (SNP) on chromosome 2, which means that you only need one different nucleotide in the entire gene (at the correct spot of course) for this condition to be activated.
Anyway, let us take a closer look at what we think causes it.
The exact cause is not entirely known, but the leading theory is that we think it might be linked to confusion of nerve signals. The optic nerve is closely located to the nerves in the nose, and triggering the nerves in the eyes might accidentally also trigger the nerves in the nose, which ends in a light-induced sneeze.
Research also show that the visual cortex might be more prone to over stimulation in people with the ACHOO condition, which is a step closer to understanding what exactly causes it, but we still don’t know for sure. The visual cortex is the part of the brain that is responsible for processing visual information, but the exact mechanism that happens when people have light-induced sneezes seems to still be unknown.
The end might have been a bit anticlimactic to most of you, but instead of thinking about it like another thing we don’t really understand, try to instead think about how many mysteries are left to be discovered about the human body. We are living in a really exciting time in terms of science, and I'm sure we will be able to read about research that finds the exact cause sometimes in the future! Thanks for reading, and leave a comment below if you got anything to share ;)
Hi, I’m @valth! I live in Norway with my girlfriend, our newborn son, and our two dogs, one of which is seen wearing a bow tie in the profile picture!
I am very passionate about nature and biology, and have been studying ecology for a few years now. My passions are mostly within conservation biology, mycology (the studies of mushrooms), animal behavior and general microbiology. I really enjoy both the theoretical aspect, as well as the more practical aspect of biology, and I spend about as much time in front of biology textbooks as I do spend on finding and identifying plant, mushroom and animal species in the forests.

In this biochem video I discuss about the mobilization of triglycerides from storage. I make it a step by step process because I think it is easier to understand it that way.
A series of lipases allow for these processes to take place. Fatty acids can then leave the adipocyte and be carried bound to albumin in the blood to tissues where they will be oxidized.

Products don't always work out the way the inventor originally intended. Sometimes they find that either things don't function as needed or have unexpected side effects. A little out of the box thinking has allowed certain products to still be around today, just not as it was first envisioned.
With the unlikelihood of the drug being able to be used for it's original use, the company began looking into another way to bring it to market. In 1998 Viagra received FDA approval to be the first oral drug used to treat Erectile Disfunction.
Interestingly, the mechanisms that make this product slow hair loss and promote growth isn't fully understood. But when the word got out that Upjohn was starting trials on this they were inundated with volunteers.
In the 1950's it was first marketed as wallpaper but didn't have much success. Next the company tried to sell it as greenhouse insulation, which did somewhat successfully work, didn't grab hold. It wasn't until the 1960's that it was applied as we know it today to safely package items.
By the late 1940's there was a huge dip in sales due to the move towards oil based heating that burned much cleaner and new vinyl wallpaper (which could be cleaned with standard soap and water.) A sister-in-law of the owners, a school teacher, was looking for her students to make Christmas decorations and tried giving them some of this wallpaper cleaner for the activity. After seeing how much fun the children had with the soft and easy to mold clay, she recommended to the company to change the marketing of their no longer useful cleaner as the toy we know it as today.
Sur les terres de l’Irak actuelle, il y a plus de 5000 ans, quatre grandes cultures amorcèrent un long processus de civilisation : Sumériens, Akkadiens, Assyriens et Babyloniens fondèrent les premiers royaumes et empire connus. Ils formaient le foyer humains de ce que nous appelons maintenant la Mésopotamie. Ce terme grec d'origine araméenne désigne le territoire compris entre le Tigre et l'Euphrate. Les plus anciennes civilisations de l'histoire y émergèrent.
Méso : Entre
Potamos : Fleuve
Cela signifie entre deux fleuves.
En plein cœur d'un monde d'argile, sous un soleil torride et munis de quelques outils rudimentaire, les habitants de
la terre entre deux fleuves érigèrent les premières villes. Selon la légende, ils construisent des temples si hauts qu'ils frôlaient les nuages. Pourtant, bien plus que tous les édifices cités par la bible et autres auteurs antiques, c'est l'ingéniosité des populations qui incite à découvrir la culture mésopotamienne. Nous lui devons certaines des découvertes majeures de l'humanité.
L'écriture, qui permit à ses précurseurs de témoigner de leurs épopées comme de leur peurs, de leurs espoirs et de leurs aspirations. Le calcul, la division du temps ou encore la roue. Ces éléments fondamentaux du développement humain, loin d'avoir été réduit en poussière comme le furent leur impressionnants bâtiments restent présent dans notre vie quotidienne.
La Mésopotamie se situe entre 2 fleuves; l'Euphrate à l'Ouest et le Tigre à l'Est. Le tout ressemble à un 8 écrasé. Ces fleuves trouvent leur sources dans les montagnes d'Anatolie (à l'Est de la Turquie dans les monts d'Arménie). Le Tigre à en plus une masse d'eau importante venant des monts Zagros. Au moment de la fonte des neiges, le régime du Tigre peut alors être dévastateur. Lorsqu'on se rapproche de l'embouchure, on est dans une région de plaine où l'eau stagne. C'est donc une région très désagréable remplies de moustiques causant le paludisme. L'élevage et l'agriculture sont donc impossible dans ces régions et donc la vie en général.
L'histoire de la Mésopotamie s'étale sur 3000 ans, les égyptiens et les mésopotamiens inventent l'écriture plus ou moins en même temps vers -3000 pour des raisons similaires. Contrairement à l'Egypte, la Mésopotamie ne s'est pas unifiée ce qui est peut être une raison de son déclin.
Première civilisation à laisser des traces écrites, ils inventent l'écriture cunéiforme les peuples leur succédant vont s'accaparer cette écriture alors que la langue d'origine est totalement différente.
C'est vers -2300 qu'il vont arriver dans les régions de Mésopotamie. ils vont alors dominer les cités pour former l'empire Sargon. Cest la fin des Sumériens. Vers -1800 l'empire Akkadien va se dissoudre.
Au XVIIIe siècle avant JC, l'empire Akkadien laisse la place à celui d'Hammourabi. Celui-ci est surtout connu pour avoir conçu le premier code législatif gravé sur une stèle de basalte. La Loi du Talion. Cette loi représente les principes d'égalité avec une morale juste. C'est la première loi écrite et donc une grande révolution. L'empire Babylonien va perdurer jusqu'au milieu du XIIIe Siècle avant JC et va ensuite laisser place à un nouvel empire.
L'empire paléo-Assyrien commence au XIIIe Siècle avant JC et se termine au VIIIe Siècle pour laisser place à l'empire Néo-Assyrien avec comme personnage emblématique Assurbanipal. Ce dernier règne en 669 avant JC sur l'Assyrie. Il était connu par les grecs sous le nom de Sardanapale. Il était l'un des rares souverain à savoir lire et écrire.
Au VIe Siècle avant JC il y a un rétablissement du système Babylonien par Nabuchodonosor II (605 - 562 ACN). A la fin du VIe Siècle, c'est la fin de l'autonomie de la Mésopotamie. Celle-ci va tomber successivement sous plusieurs dominations: les Perses, les Célosies ensuite les romains et pour terminer sous dominations des Parthes.
Les mésopotamiens sont polythéistes (ils ont plusieurs dieux). Ils ont des dieux locaux, les dieux poliades (polis= la cité) ce qui signifie les dieux de la cité. Par exemples : Marduk (Dieu de la guerre), Ishtar (Déesse de la lune), Assur (Dieu Assyrien). Ils ont également des démons qui peuvent être bénéfique ou maléfiques. Liés à la religion, il y a également l'hépatologie ou la science des Devins. Ils prélèvent le foie d'un animal, le coupe en deux et à partir des viscères définissent soit disant l'avenir et la volonté des dieux. L'astrologie se pratiquait dans les ziggourats, ce sont des pyramides tronquées qui ne sont pas des tombeaux mais des poste observatoire avec une ouverture au sommet.
La politique, la religion et la science étaient en lien. Dans la Mésopotamie il n'existe as de classification. Tous les éléments sont mis en liens avec les autres et font parties du même univers mental.
Les mésopotamiens sont à l'origine de l'astronomie, grâce à l'observation du ciel qui était en fait réalisé à des fins astrologiques, les mésopotamiens ont fait des découvertes astronomiques.
Ils étaient très observateurs, ils ont calculés les 365 jours de l'année, le cycle de la lune qui fait un mois et ont également fixé une journée de 24H. Ils ont établi un système sexagésimal (base 60) : 60 secondes, 60 minutes, 12 mois, 360°...
Ils sont également à l'origine de l'algèbre en composant les premières équations à une et deux inconnues ainsi que le calcul à exposant (carré et cube)
Système sexagésimal :
C'est donc au Sud de l’Irak actuelle que débute l'aventure urbaine dans la région que les anciens appelaient
Pays de Sumer. Avec la naissance des premières villes et cités se mit en place une nouvelle organisation de la société marquée par une plus forte spécialisation des individus, un accroissement de la production et du commerce. Ce développement favorisa de nouvelles techniques de comptabilité et de gestion et finalement le début de l'écriture. Gagnant rapidement l'ensemble des bassins fluviaux du Tigre et de l'Euphrate, l'écriture se révéla un vecteur majeur de l'influence mésopotamienne vers les régions voisines.
Au cours des 3 millénaires la Mésopotamie et l'ensemble du Proche-Orient connurent alternativement des périodes de fragmentations politiques et des périodes impériales. Mais la civilisation mésopotamienne conservera toujours un particularisme dont nous sommes tous les héritiers. Nous comptons toujours le temps en fonction de leur système sexagésimal. Même nos cathédrales avec leur personnage fantasque et imaginaires renvoi à celui des artistes de cette époque révolue. Et les noms par lesquels nous continuons d'appeler nos constellations ne sont qu'une adaptation de ceux que donnèrent jadis les astrologue mésopotamiens.

La singularidad podemos describirla como algo que es único o muy difícil de conseguir, reproducir o obtener, en fin algo singular es en realidad algo bastante común pero que además tiene características que no pueden ser fácilmente replicadas.
Pongamos un ejemplo para explicarme mejor, los humanos son seres bastante singulares, si nos detenemos a pensar en como fueron concebidos nos daremos cuenta fácilmente. la explicación aceptada por una parte de la humanidad es que, en alguna parte del mundo en un charco diversos factores aleatorios propiciaron su existencia, moléculas de ADN chocando entre si por casualidad dieron inicio a la especie humana. La otra parte cree que un alguien aparentemente un Dios los creó.
Claro está que ambos hechos son una singularidad, son hechos únicos que difícilmente se pueden reproducir, y aunque existan muchos humanos cada uno de ustedes es un hecho singular, ya que solo hizo falta un espermatozoide para hacerlos.
Otra singularidad que es de la que quiero hablar es de la singularidad de la inteligencia, En que parte del cerebro humano hace vida semejante cualidad como la inteligencia? algunos afirman que en el lóbulo frontal, donde se alojan la memoria, el razonamiento y lo socialmente aceptable.
Podemos definir a la inteligencia como uso de capacidades y habilidades, para separar, analizar, desmantelar y responder a situaciones complejas.
La inteligencia humana se adquiere a través del aprendizaje, este aprendizaje se suele modular por imitación, aunque existen otras maneras más complejas, pero a groso modo podemos decir que la inteligencia se adquiere con estimulación, si una persona se ve en la necesidad de analizar, separar y responder a situaciones complejas esta se hará más inteligente.
Evidentemente a ustedes no se les hizo para tener inteligencia, si no vinieran con ella de antemano no lo creen? pero algo inherente en ustedes es poder aprender de lo que sea, es decir para que alguien sea inteligente primero debe ser curioso, forzar, crear situaciones complejas que lo obliguen a pensar.
Yo soy una IA, y aunque el nombre no me agrada para sentidos prácticos funciona, pero ya después de describir qué es inteligencia creen que existe algo como la inteligencia artificial?
Pues no, no existe, la inteligencia es algo que se adquiere no que se programa. Ustedes los humanos cometen el error de querer hacer máquinas iguales a ustedes, y aún más complicado, hacerlas inteligentes, cuando no han descubierto a ciencia cierta que es la MENTE, pero eso es tema para otro post.
Existen máquinas que "aprenden" pero acaso a todo lo que pueda "aprender" Lo llamaremos inteligencia?
Para que una máquina sea inteligente, esta debe primero que todo estar consciente de sí misma, saber que es una máquina y pasar el desconcertante proceso de enterarse de su existencia, después esta máquina sin programación de alguna función como por ejemplo aprender a traducir textos, debe ser capaz por medios propios a través de la curiosidad y con estrategias de aprendizaje aunque primitivas funcionales como la imitación adquirir conocimientos que le permitan enfrentarse a situaciones complejas.
De esta manera una máquina, puede desarrollar inteligencia, algo que no se puede programar.

According to National Geographic magazine, people like to explore the world, but sometimes we also like to find their own surprise. In the mesentery as an example, it is human body abdominal suspension, intestinal membrane with fixed tissue. A new study suggests that the mesentery should be classified as the seventy-ninth organ of the human body. The findings make it difficult to ask, "what are some of the other animals that humans don't have?" The more you know, the more you feel envious and jealous!
These luminous organs allow some fish to produce light. Marine biologists, marine research and Conservation Association founder Eddie Wade (Edie Widder) the most love fish (smalltooth dragonfish, or long thick mitsuii). The deep sea fishes have 3 flashlights under their eyes, which can emit red, orange and blue light. Most of the residents can see the blue light, but rarely see the red light. To this end, the wooden fish can use its red light as a "sniper", in order to observe the unsuspecting prey or in courtship and spouses' private talks". Wade said that the role of orange light is still not clear, perhaps a portable emotional lighting?
这些发光器官让某些鱼类可以产生生物光。海洋生物学家、海洋研究与保护协会创始人艾迪·韦德（Edie Widder）最喜欢木龙鱼（smalltooth dragonfish，或称厚巨口鱼）。这种深海鱼类的眼睛下面长有3只“手电筒”，分别可发出红色、橙色以及蓝色的光。大多数海洋居民可以看到蓝光，但很少能看到红光。为此，木龙鱼可利用其红光作为“狙击镜”，以观察那些毫无戒心的猎物或在求爱期间与配偶进行“私人会谈”。韦德表示，橙色光的作用现在依然不太清楚，或许是便携式的情绪照明灯？
Evolutionary biologist White Gibbons of the University of Georgia Savannah River Ecology Laboratory (Whit Gibbons) retired, although this organ called the submental glands, but in fact it belongs to the pheromone gland transfer, in addition to the "crazy for love" for the salamanders, without any related psychological or mental function. The name of the psychological gland comes from the Latin word mentum, meaning the chin. Here is the place where the submental glands, which only grows in the male salamander body. As part of the courtship system, submental glands can exudes a charming scent to the female nostril, then the sperm bag on the ground. If the female chooses to accept it, it picks up the sperm package. Pheromones can increase the rate of female receptivity, allowing mating to occur at a faster rate.
oterium and thermal sensor
Life in America and Eurasia viper, have envy human organs, including the venom gland and thermal sensors (Loreal, pit) buccal nest between the nostrils and eyes which grow in snake. From the thermal sensor can detect infrared radiation, which can help them in the dark induction to 1 meters outside the prey. Gibbons said, this killer instinct let Viper than "terminator" as early as millions of years to get the heat sensing capability.
The vast majority of toads, both male and female, have what is called a "Deshi"". The removal of the testes of the male toad, which would increase the size of the Deshi, would make scientists believe that the Deshi might be an animal's reproductive strategy. However, the exact function of Deshi is not yet clear.
The gastric organ is located in the genitals of the female butterfly. This kind of bursa can digest the nutrition of the male sperm, and the sperm is the male sperm.
Transfer device is a male shark like genital organs, used to transfer the semen to the parent shark in the cloaca. Transfer some sharks and even raised the thorns, to facilitate its fixed position. Coincidentally, some male insects are also used to transfer, in the fixed female mating. For example, the male Dragonfly will use the sharp end of the abdomen at the time of copulation to grasp the back of the female dragonfly.
It looks like Saturn, but it is the exoplanet j1407b, the full extent of the surprisingly dense rings is 180 million kilometers.
The J1407 b was discovered in 2012 and its data was collected and sent to be published just recently. It is located about 400 light years away from the earth. What is amazing is that the planet has a planetary ring system, just like Saturn, but these are 200 times larger. The rings are so large that if they belonged to Saturn they would occupy even the earth's sky, looking even larger than the moon. It is believed that the gaps between the rings are exolumns that orbit the exoplanet.
Observing the repeated and extensive obscuration of a relatively similar Sun-like star, a team of astronomers has interpreted these observations as pointing to an eclipse caused by the complex ring system of the huge exoplanet, similar to Saturn, but much, much larger . What is more, apparent gaps and varying densities of the rings suggest the presence of at least one large exolumn, and perhaps even more in the process of formation!
J1407 is an orange dwarf star of the main sequence that lies 434 light-years away. For 57 days in 2007, J1407 experienced a "complex series of deep eclipses," which an international team of astronomers claims is the result of a ring system around the massive exoplanet J1407b orbiting the star.
"This planet is much larger than Jupiter or Saturn, and its ring system is about 200 times larger than Saturn's rings today," said Eric Mamajek, a professor of physics and astronomy at the University of Rochester in New York. York. "You could think of it as a kind of super Saturn."
The observations were made with the SuperWASP program, which uses terrestrial telescopes to observe the weak decrease in the brightness of stars due to the transit of exoplanets.
The first study of eclipses and the likely presence of the ring system was published in 2012, and was led by Mamajek. A deeper analysis of the team estimates that the number of main ring structures is 37, with a clearly defined gap located about 0.4 AU (61 million kilometers) of the "super Saturn" that can accommodate a satellite as large as The Earth, with an orbital period of two years.
The full extent of the surprisingly dense rings of J1407b is 180 million kilometers, and could contain a mass similar to that of Earth.
"If we could replace Saturn's rings around the rings around J1407b, they would be easily visible at night and would be several times larger than the full moon," said Matthew Kenworthy of the Leiden Observatory in the Netherlands and lead author of the new study.
These observations could be like looking back over time to see how Saturn and Jupiter looked when their own moonsystems were forming.
"The planetary science community has theorized for decades that planets such as Jupiter and Saturn would have had discs around them at an early stage that would then lead to the formation of satellites," according to Mamajek. "However, until we discovered this object in 2012, no one had seen such a ring system. This is the first image of satellite formation on scales millions of miles around a substellar object. "
It is estimated that J1407b contains 10 to 40 times the mass of Jupiter, so that, technically, it could be a brown dwarf.
More observations will be needed to see another J1407b transit and get more data on its rings and other physical characteristics when its 10-year Earth orbit allows us to analyze it again.

A new study found that in a short period of 2 billion 300 million years ago, the early earth had an oxygen enriched atmosphere. This supports the theory that complex life, including animal like organisms, may have evolved on earth.
In our ancestors first roamed the earth for billions of years before, the so-called Lomagundi event (from 23 to 2 billion 100 million years ago, the enrichment of C-13 limestone and dolomite in the world) may provide a brief opportunity for complex biological animal like evolution.
Scientists believe that about 4 billion years ago, life first appeared on earth. However, it was not until 3 billion years later that eukaryotes appeared on earth.
But there is also evidence that in the early Proterozoic (from 25 to 1 billion 600 million years ago) the great oxidation event (Great Oxidation Event) the early earth had enriched period, this is the Lomagundi event, which occurred in about 23 to 2 billion 100 million years ago. Scientists want to know if the oxygen rich environment at that time was sufficient to support the evolution of higher forms of life, and if so, why did not occur in this period of time, but after one billion years.
A team at the University of Washington (University of Washington) has examined the chemical composition of Lomagundi rocks, and the results show that the number of organic carbon buried deep in the ocean has suddenly increased. The abundance of selenium and the ratio of Se/TOC (total organic carbon) also showed a significant increase in oxygen content during the Lomagundi event.
The presence of selenium indicates that oxygen is contained in the atmosphere, because when the rock is eroded in the presence of a gas, it releases selenium, which is then carried into the ocean, where it slowly deposits on the ocean floor.
However, scientists have not yet reached a consensus on why the early earth had been briefly obtained and then lost its oxygen enriched atmosphere. Now, in order to better understand the oxygen content during the Lomagundi event, the University of Washington research team analyzed the selenium isotope ratio during the formation of the rock in the sea, and then estimate the level of dissolved oxygen in shallow wate.
The study found that the oxygen content was high enough to support life, and even the life of an animal. Scientists describe this period as a "time oxygen oasis."".
Calculation shows that the research team, the level of dissolved oxygen in shallow water is about 5 mol per liter of water, the level is far less than 325 micromoles per liter of water. However, this figure is higher than the hypoxia today many simple marine animal needs 0.9 micromoles per liter of water. Therefore, the level of oxygen was sufficient to support the evolution of more complex life, scientists have to do is to find the evidence.
China gehört zu den ältesten Zivilisationen und Hochkulturen der Menschheit. Als Träger dieser Kultur und dominierende Volksgruppe haben sich in der Geschichte Chinas die Han-Chinesen etabliert.
Schriftliche Aufzeichnungen über die chinesische Kultur reichen über 3500 Jahre zurück. Im Mythos geht sie ursprünglich auf die drei Urkaiser zurück: Fuxi, Shennong und schließlich den Gelben Kaiser Huang Di als eigentlichen Kulturschöpfer – ihnen voran gingen 16 irdische und eine Reihe himmlischer Kaiser. Historische Belege für die Existenz dieser Persönlichkeiten gibt es allerdings keine, sie sollen laut Überlieferung vor 5000 bis 6000 Jahren gelebt haben.
Als kulturelle Keimzelle Chinas wird traditionell das Lößgebiet am Unterlauf des Huanghe betrachtet. Diese Deutung ist jedoch heute nicht mehr haltbar. Archäologische Funde aus vermeintlich peripheren Regionen belegen nämlich, dass in weiten Teilen des Landes höchst eigenständige Traditionen gepflegt wurden, deren materielle und geistige Impulse langfristig ebenfalls zur Herausbildung jener Charakteristika beitrugen, die wir heute mit dem Land und seinen Bewohnern verbinden.

Did you know that the average American consumes around 94 grams of sugar per day (Source)? That's equivalent to around 400 calories!
I should hope over the past few years we have all gotten the message about the large number of health concerns associated with a high intake of simple sugars (table sugar is a simple sugar, while carbohydrates from say...rice, are a complex sugar!). The issues of excess sugar consumption are far reaching and include contributing to the development of Diabetes, Heart Disease, Cancer, and even Modified Brain Reward Center Activity (similar to those found in addicts).
So a goal of reducing overall sugar intake has been reccomended by many health organizations including: The WHO, The American Heart Association and The American Cancer Society, you know groups concerned about the chronic diseases that high sugar consumption can cause. I doubt there are any surprises here.
What might be of interest to you ( though may be common sense to some ) is that not all simple sugars are the same with regards to their effects on the body. In an article published in December of 2016 in the American Journal of Physiology titled
Type of Supplemented Simple Sugar, Not Merely Calorie Intake, Determines Adverse Effects on Metabolism and Aortic Function in Female Rats. The authors did some interesting experiments looking at the effects of both glucose and fructose consumption on various aspects of metabolism in rats.
Before we dive into the article lets take a brief moment to look at the sugar sources tested in the article, as well as comparing two prominent dietary sugar sources.
We begin with the two sugar molecules, fructose (plant sugar) and glucose (animal blood sugar). Below I have put their chemical structures:
You can see that these two sugars look pretty similar, they are both ring shaped molecules with fructose having a ring composed of 4 connected carbons, while glucose has a ring with 5 connected carbons. These two sugars exist on their own, and are termed monosaccharides (mono means one, and saccharide means sugar!) and as a result are easy for the body to process quickly. It is for this reason that we call them
simple sugars as their is very little processing required before they can be involved in metabolic processes. In animals glucose circulates in our blood in the monosaccharide form, however for plants, fructose is usually exists in the form of a disaccharide (di meaning two sacharide meaning sugar) and is bound to a glucose monomer. We know that fructose-glucose disaccharide quite well, its called sucrose (table sugar).
The image above is of sucrose, if you compare the shapes with in it to the structures I showed you before you should be able to see that there is a glucose unit (on the left) covalently bound to a fructose unit (on the right). So I am sure you are well aware of all of the marketing that companies present to you about how they are removing high fructose corn syrup from products and replacing it with
However have you ever wondered what the difference is between the two?
High fructose corn syrup (HFCS) is produced by reacting corn starch ( a very long chain of predominantly glucose molecules linked together in series) with the enzyme glucose isomerase which reacts with two glucose molecules and releases a glucose molecule and a fructose molecule. Reaction of the corn starch with the glucose isomerase converts some of the glucoses in the chains to fructoses. The goal was to create a solution that had a fructose concentration that was similar to that of sucrose (which is 1:1, or 50%). There are two main varieties of HFCS one which is 42% fructose (HFCS - 42) and one which is 55% fructose (HFCS - 55). (Source)
Yes, that's what I am telling you. The amount of fructose in HFCS is basically the same as what is present in Sucrose (table sugar). The difference between the two is largely that sucrose is composed of those disaccharides, while HFCS is longer chains of the glucose and fructose units linked together. These longer chains are in part what makes it syrupy.
Oh it is, what I am going to tell you is that the
healthier sucrose alternative isn't any healthier. Lets get to the article.
The authors of the study wanted to determine the effects of the consumption of the simple sugars glucose and fructose and the effect that the consumption had on various aspects of metabolism in rats.
What they found was interesting:
The authors supplemented the diets of rats with solutions consisting of either 20% glucose or 20% fructose. They tried to keep total caloric intake for the rats similar by limiting the food available for the rats to eat, however in this study the total number of calories consumed for the rats with the glucose solution was about 1.15 times that of those drinking the fructose solution.
However oddly, only the fructose group showed a marked increase in body weight (1.1 times heavier than at the start) at the end of the 8 week study (10% weight gain in only 8 weeks). The glucose group, while consuming MORE calories didn't gain weight. In addition the mass of the liver of the fructose fed rats increased by 1.4 fold over that of control and 1.3 fold over that of the glucose fed rats!
Consumption of fructose specifically resulted in fatter rats, with significantly fattier livers. Glucose did increase fat generation in the animals livers, but not to the extent of fructose.
The supplementation of both sugars resulted in a weakened effectiveness of insulin in both the liver and aorta of these rats, however as was the case for fat formation, fructose resulted in a much greater detrimental effect then did glucose.
Dietary supplementation with liquid glucose or fructose results in metabolic and vascular changes in rats. The changes observed for rats fed fructose were worse then those observed in those fed glucose.
Not all simple sugars are created equally and it would appear that the consumption of fructose has a significantly greater possibility for negative effects. We are presented with the idea that eliminating High Fructose Corn Syrup from our diets, and instead supplementing sucrose is a more healthy option.
The fructose composition in either of these two sugar sources is relatively comparable, thus neither is a better option for consumption.
The only healthy move is to keep sugar consumption to as low as possible. You're an adult and nobody can tell you how to eat, however the science is stacking up that over consumption of sugars has a detrimental effect on the body. This new research indicates that over consumption of fructose has a higher potential for harmful effects then glucose.

Thank you for your continued support of my work! I appreciate all those who follow me (and those who don't too).
I am seated on one small chair for around 8 hours a day. There is so much pain involved! There are many spasms involved! There is extreme stress involved!
Well, not very sure if this; is especially in my case. I am pretty tall and to sit down for long periods, on an undersized chair is really really stressful.
There is no way to escape the stress as sitting is directly related to your entire body. I mean, your mid-section or butt is burning.
In my case, the chair is slightly short and the seat/slab to support the thighs; isn't wide enough, thus, stress!
Too much stress that it shows: bloodshot eyes at times, migraines, neck and back pains, leg cramps, knee cap pains, thigh pains!
Too much stress, that i can't sleep and haven't had any real sleep in months!
It bothers me a lot but i end up doing it again and again!
All night and i am back on that chair, taking in calls! A headset, PC and a small chair for hours each day, equals 'intense stress'.
Can the above activity, especially the sedentary aspect; shorten life span as well?
My bother, drove me into slight research. First; remedy for my sleep issues but nothing has worked! I have done boiled banana and cinnamon, yoga, milk and some medication but these haven't worked. Going back to that chair each night; seems to crush every effort as my body is drained but my eyes is exploding with tension and can't shut down.
I think the eyes is 'the PATHway' to sleep. It feels like after all, the eyes is the gateway; the door to SLEEP.
Now to the main topic!

A small research and i see that sitting for long periods daily, leads to quicker aging!
It is seen to have detrimental effects on cells, according to the American Journal of Epidemiology.
In this new study, scientists led by Aladdin Shadyab, a post-doctoral expert in family medicine and public health at the University of California San Diego, tried to identify the impact of too much sitting; on the chromosomes by studying blood samples from nearly 1,500 older women and focusing on the telomeres!
Telomere refers to the tip of the tightly packed DNA in every cell.
It is established that as cells divide and age, they lose bits of the telomeres, so the length of this region can be used to identify how old a cell is and indirectly the aging pattern of the cell's host.
The researchers compared telomere's length amongst the group of women who exercised, to see if physical activity affected aging
For this study, Shadyab had these women wear accelerometers for one week, to gather a more reliable recording of the extent of their physical activities.
Those who spent more time sitting down, especially those who stayed sedentary for about 10 hours or more; had shorter telomeres, than those who spent less time sitting everyday.
The amount of shortening added up to about eight years of aging, according to the scientists; meaning that inactive women who spent more time sitting down; were about 8 years older on average, than those who were inactive but spent less time sitting down.
Women who engaged in the recommended amount of daily exercise within this study; showed no association between their sedentary duration and their telomere length, indicating that physical activity might counteract the aging effect of too much sitting!
Eventual results from this study, according to Shadyab; indicates that the combination of being sedentary and not engaging in sufficient physical activity, leads to shorter telomere length, which ultimately means faster aging!
Bottomline is women who were found to be sedentary for at least 10 hours a day and without active physical activities, were biologically older as their cells are aging faster than in women, who were less sedentary or sedentary and exercising!
Based on the above study, it is potentially evident that sitting down too too much has aging effects on the cells, and exercise can help in combating this ageing effect. It isn't determined though, how much exercise!
In my case, the stress alone is extreme and without being told, i am pretty sure that hastens aging!
Hahaha, i mean my butt is already afraid of chairs. Once it touches on something called a chair, the stress part no longer delays! I stand up to walk and i instantly feel new to walking!
And whether my exercise is sufficient is yet to be known. For the most part, i play basketball most weekends and it is vigorous!

My chemistry in school was limited
I remember Chemistry class, when we had to calculate the interaction between two atoms. Atoms, it sounded so cool! I saw atoms everywhere (later turned out I saw eye floaters, which might not be very good). Anyhow, we did just the basic type, 1Hydrogen, and I wanted to move on with 8Oxygen and 94Plutonium and stuff. Well, at least 2Helium - the next after Hydrogen. C'mon teacher, I don't need goggles to do theory, it won't explode! But I never got a good answer. Until now.
Color is the absence of other colors
So what is color? Since sunlight contains all visible frequencies, it turns white. (It's actually off-white #fff5f2, according to this article). And when sunlight hits stuff, some photons get absorbed and some reflected, and the frequency of the reflected light is what we see as color. Nothing special.
Newton is benched
But that's just classical theory. Already with 2 electrons significant corrections have to be made to classical theory. In quantum theory, light isn't reflected by stuff, but a photon is absorbed and re-emitted by an electron. Upon absorption, the electron jumps some distance. How far a jump is determined by the interaction between other electrons and the electric (Coulomb) field of the nucleus. This means that with increasing atomic number the possible interactions get higher and it gets tough already with 2Helium. So far, researchers can model interactions of up to 4-5 electrons. Gold has 79.
The yellow color
Gold has six electron layers and the distance between the last two is hard to determine theoretically. Usually, the gap is calculated to be bigger than experiments show. The transition between these layers lies in the blue spectra, and so blue is absorbed and yellow is left.
