CELLS alive! //// A PLAT VENTRE ///////////////////////////////////////////// The Man Who Would Stop Time Bill Andrews’s feet are so large, he tells me, that back when he was 20 he was able to break the Southern California barefoot-waterskiing distance record the first time he put skin to water. Then he got ambitious and went for the world speed record. When the towrope broke at 80 mph, he says, “they pulled me out of the water on a stretcher.” The soles of the size-15 New Balances that today shelter those impressive feet strike a steady clap-clap on the macadam as Andrews and I lope down a path along the Truckee River that takes us away from the clutter of cut-rate casino hotels, strip malls and highway exit ramps that is downtown Reno, Nevada. That would indeed be ironic. Andrews had scheduled this afternoon’s run as an 18-miler, but he graciously downscaled those ambitions on my behalf long before we set out from the parking lot of the Grand Sierra Resort Hotel. The embrace of fitness has for Andrews a telomeric logic. Youth Elixir “A magic pill?” Asleep in the Lab Mission Control

Secret Worlds: Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Earth = 12.76 x 10+6 = 12,760,000 meters wide (12.76 million meters) Plant Cell = 12.76 x 10-6 = 0.00001276 meters wide (12.76 millionths of a meter) Scientists examine things in particular ways using a combination of very sophisticated equipment, everyday instruments, and many unlikely tools. Note: - The sequence of images in this tutorial has been optimized for maximum visual impact. Contributing Authors
Synchronizing Clocks previous home next PDF Michael Fowler, UVa Physics 2/29/08 Suppose we want to synchronize two clocks that are some distance apart. We could stand beside one of them and look at the other through a telescope, but we’d have to remember in that case that we are seeing the clock as it was when the light left it, and correct accordingly. Another way to be sure the clocks are synchronized, assuming they are both accurate, is to start them together. If, then, we place a flashbulb at the midpoint of the line joining the two clocks, and flash it, the light flash will take the same time to reach the two clocks, so they will start at the same time, and therefore be synchronized. Let us now put this whole arrangement - the two clocks and the midpoint flashbulb - on a train, and we suppose the train is moving at some speed v to the right, say half the speed of light or so. Let’s look carefully at the clock-synchronizing operation as seen from the ground. from which tB is given by previous home next PDF

The Best Edible Science Experiments You'll Actually Want to Eat Hands-on science experiments and projects are always a hit with kids, in the classroom and at home. Want to make them even better? Make them delicious, too! Of course, you’ll want to use common sense about safety and good food hygiene along the way. 1.

A Guide to “Hollywood Ugly” | Uproxx In February 2002 during their 11th season, The Simpsons skillfully summarized the idea of „ugly” people in major motion pictures: What is considered homely in Hollywood is “Mary Ann on Gilligan’s Island (…) TV ugly. Not ugly-ugly.” Look at that disgusting pig No one is holding it against movies for being escapist; God knows we have more than enough stuff to escape from (jobs, families, neighborhood drug dealers who still haven’t been paid). Due to many technical and legal limitations I cannot outright support the ingestion of powerful narcotics to get you into the mind of the people behind the idea of Hollywood Ugly, but I can do the next best thing and analyze just what idiotic tricks are used to achieve this effect. Imperfect = Monstrously Ugly Let’s talk about the opera… It’s boring. The Phantom living under the opera house is supposed to be hideous, a real monster (think the bastard love child of John C.
