The Mystery Behind Anesthesia Going under: Emery Brown’s quest to understand how anesthesia affects the brain could provide crucial clues about what goes wrong in certain disorders. A video screen shows a man in his late 60s lying awake on an operating table. Just outside the camera’s view, a doctor is moving his finger in front of the man’s face, instructing him to follow it back and forth with his eyes. Seconds later, after a dose of the powerful anesthetic drug propofol, his eyelids begin to droop. Then his pupils stop moving. As an anesthesiologist at Massachusetts General Hospital (MGH), Brown is constant witness to one of the most profound and mysterious feats of modern medicine. But though doctors have been putting people under for more than 150 years, what happens in the brain during general anesthesia is a mystery. “By taking away different functions that we associate with consciousness,” Brown says, “we might be able to start piecing together parts of the jigsaw puzzle.”

In the meantime, the general public began to recognize the use of codes and ciphers, and simple cryptosystems came into popular use. * The Arab world was well ahead of the West in cryptanalysis, but in European monasteries, monks engaged in analysis of Biblical texts kept interest in cryptology alive in the West. Their interest was provoked partly by the fact that the original Hebrew sources of the Old Testament actually include enciphered words, though more as a literary gimmick than to keep secrets. The French codebreaking tradition began with Philibert Babou, who was followed by Francois Viete. use the force luke -- gives: -- and so on.
"The egg" - Page 11 You were on your way home when you died. It was a car accident. Nothing particularly remarkable, but fatal nonetheless. You left behind a wife and two children. And that’s when you met me. “What… what happened?” “You died,” I said, matter-of-factly. “There was a… a truck and it was skidding…” “Yup,” I said. “I… I died?” “Yup. You looked around. “More or less,” I said. “Are you god?” “Yup,” I replied. “My kids… my wife,” you said. “What about them?” “Will they be all right?” “That’s what I like to see,” I said. You looked at me with fascination. “Don’t worry,” I said. “Oh,” you said. “Neither,” I said. “Ah,” you said. “All religions are right in their own way,” I said. You followed along as we strode through the void. “Nowhere in particular,” I said. “So what’s the point, then?” “Not so!” I stopped walking and took you by the shoulders. “You’ve been in a human for the last 48 years, so you haven’t stretched out yet and felt the rest of your immense consciousness. “Oh lots. “Wait, what?” “Sure.
Mathematics MIT Culture Vaults : Resonant Frequencies and the Human Brain One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions. Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. When we hear a sound, our eardrums are actually being vibrated by subtle waves in the air molecules around us. Even the neurochemical processes of human consciousness our very thoughts ring with their own distinct wave patterns. By studying the way that waves interact with other waves, researchers have found that even low-powered oscillations can have enormous effects on standing waves, physical structures, and even the human brain. Tesla first realized the massive potential of resonant waves in 1898 when he performed a simple experiment with an electromechanical oscillator the size of an alarm clock. "The principle cannot fail," Tesla would say. Monroe's Big Discovery The Neural Radio
Camping Knots for Wilderness Survival By Filip Tkaczyk Knowing how to tie good camping knots is an invaluable skill in wilderness survival situations. Its also a great asset when having fun in the outdoors. There are a wealth of different knots out there that you can learn to tie. With so many different knots, you might find it hard to choose which to learn first. Square Knot Also called a reef knot, this knot is useful for tying bandages, packages and joining shorter pieces of rope together. To begin, lay the ends of the ropes parallel and then pick up a rope in each hand. Now tie an overhand knot as you would for tying your shoe laces by putting the right end under and over the left rope end. Then tie another overhand knot, this time putting the left end under and over the right rope. Completed Square Knot Clove Hitch Like all hitches, this camping knot ties a rope to an object. To begin, bring the rope end over and under the post. Now, bring the rope end around a third time, and tuck it under the center of the X. Bowline
