POPSGrand Illusion!!! The Mystery Crash
courtesy of Luxman, Luxenbourg. Hunt the Boeing! And test your perceptions! As everyone knows, on 11 September, less than an hour after the attack on the World Trade Centre, an airplane collided with the Pentagon. The Associated Press first reported that a booby-trapped truck had caused the explosion. The Pentagon quickly denied this. The official US government version of events still holds. Here's a little game for you: Take a look at these photographs and try to find evidence to corroborate the official version. It's up to you to Hunt the Boeing! Did you find the Boeing? Can you still defend the official version of events? > Well done! Remember to get in touch with master of illusion, David Copperfield. He'll be glad to hear from you! You found the official version lacking in something (like a Boeing, for example): > If you begin to question whether a Boeing really did crash on the Pentagon then, no doubt, you'll be wondering what happened to the aircraft that disappeared

POPSAn Algorithm with No Secrets A hash algorithm turns an ordinary message into a "digital fingerprint," which can then be used to keep the original message secret during transit or to guarantee that it hasn't been tampered with en route. But a hash function is only considered secure if there is no practical way to run it backward and find the original message from the fingerprint. Equally important, there should be no trivial way to produce two messages with exactly the same fingerprint. The weaknesses discovered by Wang and others relate to this problem--something cryptographers call "a collision." The latter issue is complicated by the fact that it is impossible to completely avoid collisions. So the best algorithm is one that simply makes collisions extremely hard to produce. "You shouldn't be able to find them," says William Burr, manager of the Security Technology Group for NIST. "The computation should be too great."

POPSScientists find something good about a big bottom Researchers have known for some time that fat that collects in the abdomen -- known as visceral fat -- can raise a person's risk of diabetes and heart disease, while people with pear-shaped bodies, with fat deposits in the buttocks and hips, are less prone to these disorders

POPSI Found Your Dog Today..... And despite all my persuasion, his eyes see a stranger. He did not trust. He would not come. He turned and continued his journey; one he was sure would bring him to you. He does not understand you are not looking for him. He only knows you are not there, he only knows he must find you. This is more important than food or water or the stranger who can give him these things. Persuasion and pursuit seemed futile; I did not even know his name. I drove home, filled a bucket with water and a bowl with food and returned to where we had met. I could see no sign of him, but I left my offering under the tree where he had sought shelter from the sun and a chance to rest. You see, he is not of the desert. When you domesticated him, you took away any instinct of survival out here. His purpose demands that he travel during the day. He doesn't know that the sun and heat will claim his life. He only knows that he has to find you.
