We all have moments in life we regret and wish to change; be it having never worked up the courage to ask that girl to the prom back in high school or not picking 42, 15, 72, 17, 28 and 6 for our Powerball numbers last week, if only we could somehow alter events in the past. Or perhaps we would like to skip ahead into the distant future where we can fight space aliens using our Lightsabre app on our smartphones (hopefully the battery life is better by then). These possibilities all boil down to the following questions: Is time travel possible? And if so, would there be any point to the limited availability of the McRib?
Now obviously I don't mean in the trivial sense - I very much realize we're all technically slogging along through time at 1x speed with no choice in the matter. But is there a way to hit the fast forward button through all the boring parts in life like in that Adam Sandler film Click,
Since 1961 the equation has been updated to take into
Today lets focus on a hormone that many of you might be familiar with due to its involvement in helping us fall asleep. This hormone is called N-acetyl-5-methoxy tryptamine, or as you may know it by the less chemical name, Melatonin.
Melatonin is a hormone produced by a small gland in our brains called the pineal gland and is as I said above, important for regulating our sleep/wake cycle (it signals to your brain that its sleepy time). The pineal gland is also thought to be involved in secreting compounds which regulate hormone secretion from another gland called the pituitary gland (this is where the sex hormones come from), but I digress.

In 1928, Sir Alexander Fleming discovered a bacteria destroying substance known as Penicillin, paving the way for antibiotics, which is a major landmark in the advancement of medical science.
It allowed for the perfection of treatment of bacterial infections which used to claim hundreds of thousands of lives before its accidental discovery and further development.
Since then countless lives have been saved, and today, many diseases that were once feared as life-threatening are easily cured. Some are even on the verge of extinction, leading to a higher life expectancy and a better life for us humans.
As with other advancements, antibiotics have proven to be a double edged sword and now we are on the verge of a potential pandemic that could claim millions of life.
The ease with which antibiotics are av
I have been fascinated to see two of these technological marvels that have been "planted" in a town near my home. Their installation is a collaboration between the "city" of Chiasso and Age SA, a local electrical company.
This Smartflower has been "planted" in a roundabout near my home.
The design is an attempt to combine the functionality of solar panels with the beauty of an appealing design. It was produced for those that don’t have the possibility of using a classic roof top solar panel installation and would like something on the ground that doesn’t look ugly!
Since a year there is a project running where supercomputers are used to try and find collision keys in BTC wallets which have balance. Yes before nanocomputers came already bitcoin collider project is doing this using decentralized computers and they claim to already have cracked some wallets and got funds out.
Speaking shortly like currently you can mine in pools to find a block, they made software which allows you to pool mine for private keys.
After checking code of their miner a lot of peopel raised flags. Of course since they are looking for priv keys it may not be real ones - check for yourself. People claim their miner executes extra code on your computer. So if you want to use this - better get another computer whi
Artificial intelligence has come a long way in the last couple of years. A major breakthrough last year was AlphaGo - beating humans at Go, a game so thoroughly random it simply couldn't work by calculating all possible scenarios (like Chess). Indeed, there are more permutations to a Go game than there are atoms in the observable universe! The only way to be good at Go is through sheer creativity and experience.
AlphaGo is a cutting edge machine learning AI that uses a neural network to rapidly learns by discovering patterns in existing data. In the case of AlphaGo, this would be by looking at historical games and training by playing with humans and with itself. By absorbing information from millions of games, AlphaGo was able to beat the leading Go players in the world.
Last year, Microsoft released a bot on Twitter, Tay, that would respond to twee
Technologies that have been proposed for use in starship propulsion include ion engines, solar sails, antimatter engines, fusion engines, and the theoretical Alcubierre drive, or warp drive. These self-contained vehicles would contain a full life support system for their crew, allowing long term habitation. They would need to act as fully closed ecosystems, utilizing near 100% recycling efficiency for water and air. Large scale food production would require the implementation of hydroponic farming, and
17 million barrels of crude oil are needed to produce that much plastic - which would be enough oil to fuel 1 million cars for a whole year.
We all know that pollution and plastic are bad - but plastic water bottles are a major part of that.
And some countries (like the US) still don't have proper bottle deposit systems!
It's convenient to store water bottles ready for on-the-go, and some countries don't have high quality tap water - but still, plastic bottles desperately needed an alternative!
edible water bottle: it's a bio-degredable, edible bubble which can be filled with water or other liquids!

The drop in soda consumption has been regarded as the single most significant change to the average American diet over the past decade.
Many health experts maintain that soda isn't the best option to go with for a drink if you are looking to foster optimal health. And researchers have recently sought to further investigate the possible link between soda consumption and the brain to find out if there is any cause for concern.
For their study they invo
We have seen it in the healthcare field, in electronics, on bike helmets, even in the fashion industry. It really seems like graphene has no limits and there are still many people around the world who have yet to learn about this amazing material and all that it can offer.
To try and fill that gap, a new National Graphene Association (NGA) has been formed to try and spread awareness about the material throughout the US market and to promote American graphene.
The association was launched by an Oxford-based company,New Media Lab LLC,
We are still working with Decision Trees and in this video we're specifically going to look at a parameter of the trained algorithm, which is called feature_importances.
We can call this parameter after the classifier (our Decision Tree) has been trained on the cancer dataset and it will show us how much weight each feature carries in the decision making process. This will aid our understanding of the entire process. However, despite having some features weigh more than others in classifying tumors, it is always advised to be considerate of the context.
In this case, 'worst radius' carries the most weight for decision making. But it wouldn't be advised to say that a larger value of this is directly associated with a tumor being 'malignant' or 'benign'. Please watch the video for a more detailed walk-through of what I just said.
As a reminder:
In this series I'm going to explore the cancer dataset that comes pre-loaded with scikit-learn. The purpose is to train the classifiers on this dataset, whic
The naked mole-rat (Heterocephalus glaber) is a really weird animal that is very unique in terms of adaptations. For one, it is the only cold-blooded mammal in the world, and uses thermoregulation kind of like reptiles do. It also cannot feel pack due to lacking the key neurotransmitter that is responsible for sending pain signals, as well as it having a natural resistance to cancer. Yeah, it is pretty much strange is every way.
This is truly a remarkable animal that is worth studying, and a group of scientists recently discovered that they are able to survive in conditions with extremely low oxygen concentrations. By putting them into boxes with only 5 % oxygen (compared to the normal 21 % in air), which would kill humans and most other animals within minutes, they did not die, and were in fact alive and well after five hours. After this time, they were removed from their boxes, so no one really knows how long they could survive during these conditions, or if they are even able to survive permanently in
Each man should frame life so that at some future hour fact and his dreaming meet.
Why do we dream…
To be honest with you.., NOBODY KNOWS!
End of post.., thank you very much.
No seriously.., nobody knows why we dream… There are all kinds of theories, but a definitive answer, as to why we actually dream, has alluded us. One of the earliest theories was developed by Aristotle and Plato (that long ago).., and their theory was that; people dream as a way of acting out unconscious desires, in a safe setting.., because if we were to do so in the real world, it may be considered unacceptable or even harmful to ones health or mortality.
And right up until present day, with all of the understanding we have of so many things, all the technology.., we still have no idea wh
The cell saga was FIRE!!! Trunks came back from the future with the Z sword, Vegeta came out the hyperbolic time chamber in top shape, Goku was out with the heart virus, aw man... And Cell!!! Cell was one of the best super villains ever. For a little bit it really didn't seem like the Z fighters would be able to beat him. I remember coming home after school watching DBZ on Toonami calling my friend on the phone after each episode, then talking to him about the same episode everyday until the next episode came out.
I don’t know what I would do with my life I could't make any gainz. Even though when, at my best as a lifter I focused more on strength, the hypertrophy of my muscles were pretty cool. There's a cool little feeling of accomplishment you get when you see your mu
Hey folks, over the course of this series of posts, we will try to gain an understanding of some of the key concepts in magnetism. Some of this treatise will be mathematical, but I'm hoping I can convey the underlying ideas in an accessible manner. In this first installment, we will get some of the basics sorted.
These are the fundamental 'objects' in magnetism. Imagine, for a moment, within the regime of classical electromangetism, that we have a current loop. Now, if this loop is vanishingly small, with an area |dS|, then the magnetic moment, d(mu) is given by
which has units of A m^2. The length of the vector dS is equal t
PIONEERS OF SCIENCE: EINSTEIN'S GENERAL RELATIVITY.
In the last essay in this series, we saw that Einstein had found that his Special Theory of Relativity conflicted with Newton, and that this had something to do with the Sun vanishing. So, what would happen if our parent star were to do that? Well, surprisingly, we would go about our lives as if nothing had happened. This is because light travels at finite speed, and at 160 million miles per hour it takes about eight minutes to travel the 149, 597, 870 km to Earth. Think of the oncoming darkness behind the last wave of light as akin to ripples spreading out on a pond after a stone impacts its surface. But, bathing our world in warmth and light is not the only influence the Sun exerts on our planet, because its gravity is what keeps all the planets, moons, asteroids and comets locked in orbit around it. Newton had calculated that the force of gravity was dependent on the mass of an object and the square of the distance between objects. From this assumption,
The Tasmanian Tiger (Thylacinus cynocephalus), also known as Thylacine, was a carnivorous marsupial native to the Australian continent, Tasmania and New Guinea. Despite being named after the tiger (Panthera tigris), it is not at all related to it. In fact, it behaved more like a wolf (Canis lupus), but in reality it is not closely related to any of these species at all. During the early 1900s, most of the “tigers” were hunted down, either for trophy hunting or for protection of farm animals, and this quickly lead to a total extinction. In 1936, the last known Tasmanian Tiger died in Hobart Zoo on Tasmania.
Despite the fact that the Tasmanian tiger is considered extinct by pretty much everyone, the occasional person claim to have seen one while hiking in the southern part of Australia or on Tasmania. There are also a few sketchy videos floating on YouTube and sites like that, but of course no one them are good enough to actually prove that the animal in question is a Tasmanian tiger.
