Someone told me that if there are 20 people in a room, theres a 50/50 chance that two of them will have the same birthday. How can that be?& This phenomenon actually has a name -- it is called the birthday paradox, and it turns out it is useful in several different areas (for example, cryptography and hashing algorithms).
You can try it yourself -- the next time you are at a gathering of 20 or 30 people, ask everyone for their birth date. It is likely that two people in the group will have the same birthday. It always surprises people! The reason this is so surprising is because we are used to comparing our particular birthdays with others. For example, if you meet someone randomly and ask him what his birthday is, the chance of the two of you having the same birthday is only 1/365 (0.27%). When you put 20 people in a room, however, the thing that changes is the fact that each of the 20 people is now asking each of the other 19 people about their birthdays. If you want to calculate the exact probability, one way to look at it is like this. 364/365 × 363/365 × … 365-20+1/365 = Chances of no collisions. Human World - StumbleUpon.

5 Ways To Hack Your Brain Into Awesomeness. Much of the brain is still mysterious to modern science, possibly because modern science itself is using brains to analyze it. There are probably secrets the brain simply doesn't want us to know. But by no means should that stop us from tinkering around in there, using somewhat questionable and possibly dangerous techniques to make our brains do what we want.
We can't vouch for any of these, either their effectiveness or safety. All we can say is that they sound awesome, since apparently you can make your brain... #5.

Solipsism ( i/ˈsɒlɨpsɪzəm/; from Latin solus, meaning "alone", and ipse, meaning "self")[1] is the philosophical idea that only one's own mind is sure to exist.
As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind. As a metaphysical position, solipsism goes further to the conclusion that the world and other minds do not exist. Varieties[edit] There are varying degrees of solipsism that parallel the varying degrees of serious skepticism.
[edit] Epistemological solipsism[edit] Epistemological solipsism is the variety of idealism according to which only the directly accessible mental contents of the solipsistic philosopher can be known. Methodological solipsism[edit] Methodological solipsism may be a sort of weak agnostic (meaning "missing knowledge") solipsism.

While Nigeria’s 401 scammers may have written the book on West African internet fraud, their shtick looks like Compuserve compared to what’s going on in Ghana. Unsatisfied with the meager winnings from emailing thousands of random Westerners in hopes of convincing one poor sap they’re the treasurer of the Ivory Coast, Ghana’s scammers decided to stack the odds in their favor the old-fashioned way—witchcraft. Taking a page from cyberpunk, traditional West African Juju priests adapted their services to the needs of the information age and started leading down-on-their-luck internet scammers through strange and costly rituals designed to increase their powers of persuasion and make their emails irresistible to greedy Americans.
And so “Sakawa” was born. Now not only is Sakawa Ghana’s most popular youth activity and one of its biggest underground economies, it’s a full-blown national phenomenon. —Watch more at Motherboard.tv. Skinner on Campus.

O’Sullivan – Battle of Gettysburg This photograph has become synonymous with The Battle of Gettysburg, which was the most bloody battle of the American Civil War. Photographer Timothy H. O’Sullivan documented and recorded the battlefield, and this picture became a sensation. For many, this was their first chance to see, first hand, the true extent of the Civil War.
However, it was not until 40 years after the battle that the pictures were mass produced, as photo-engraving had not been established. The picture shows dead confederate soldiers on the battlefield, and has earned its place in history as an iconic photograph.

America's Freak Luck During the Battle of Midway The Battle of Midway may be remembered as one of the most spectacular naval battles in history and one of the huge turning points in the Pacific theater, but it started out as a pure clusterfuck for the Americans.
Despite going into battle with most of Japan's game plan in their pocket thanks to American codebreakers/Bothan spies, the U.S. Navy had little to show for it in the early hours of June 4, 1942. Just about every aircraft that took on the Japanese that day was destroyed, and all without delivering any serious damage. Where it Gets Weird: There was one squadron of American dive bombers lead by Lieutenant Commander C. His squadron started dropping like flies until, in an act of sheer luck that would make even J.K. Where it Gets Even Weirder: This winning of the lottery twice in the same day dealt the Japanese Navy's first defeat in almost 300 years, and a lopsided victory for the Americans that the Imperials never recovered from.

While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? 273.15°C, where the motion of all particles stops completely. One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble.
One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well.

Top 10 Civilizations That Mysteriously Disappeared | Top 10 Lists | TopTenz.net - StumbleUpon. Throughout our history, most civilizations have either met a slow demise or were wiped out by natural disasters or invasion.

The first signs of the Olmec are around 1400 BC in the city of San Lorenzo, the main Olmec settlement which was supported by two other centers, Tenochtitlan and Potrero Nuevo. Where did they go? Around 400 BC the eastern half of the Olmec’s lands was depopulated- possibly due to environmental changes. 9.
