Want to really get away from it all? The farthest you can travel from home (and still remain on Earth) is about 7,900 miles (12,700 kilometers) straight down, but you'll have to journey the long way round to get there: 12,450 miles (20,036 kilometers) over land and sea. Why not take a shortcut, straight down? You can get there in about 42 minutes -- that's short enough for a long lunch, assuming you can avoid Mole Men, prehistoric reptiles and underworld denizens en route. Granted, most Americans would end up in the Indian Ocean, but Chileans could dine out on authentic Chinese, and Kiwis could tuck into Spanish tapas for tea [sources: NOVA; Shegelski]. Of course, you'd be in for a rough ride. For sake of argument (and survival) let's pretend the Earth is a cold, uniform, inert ball of rock. At the Earth's surface, gravity pulls on us at 32 feet (9.8 meters) per second squared. You're still moving at a heck of a clip, though, so don't expect to stop there.

Why are past, present, and future our only options? But things get awkward if you have a friend. (Use your imagination if necessary.) Low blow, Dr. Dave. Low blow... But seriously, I always figured if there was more than one dimension of time, that moving "left" or "right" would be the equivalent of moving to a parallel universe where things were slightly different. Incoming! The World’s 10 Worst Invasive Species The introduction of non-native species of plants and animals to a new ecosystem almost always results in environmental stress, degradation and sometimes even disaster. These 10 invasive species are infamous for the destruction they have caused, even when introduced with the best of intentions. Kudzu (images via: Free Republic, JJ Anthony and Cynical-C) Kudzu… its name may sound like that of a Japanese movie monster and this pretty ornamental vine does indeed originate in Japan (and southeast China) – and has caused extensive destruction to boot. The only plant on this list, kudzu earns a place in the annals of misguided attempts to introduce foreign species because it was one of the first such invaders to be noted, publicized and controlled.

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing.

Does the Color Pink Exist? Scientists Arent Sure In a blog post, Robert Krulwich of the public radio show Radiolab noted that there is no pink in the colors of the rainbow. Pink is actually a combination of red and violet, two colors, which, if you look at a rainbow, are on the opposite sides of the arc. Remember the old colors of the rainbow mnemonic ROYGBIV? The R (red) is as far as it can get from V (violet). That’s where the trouble lies.

The record clerk took the photographs above and, thinking he remembered West, asked whether he had been there before. West said no. The clerk took some measurements, went to the file, and produced this record, bearing the name William West:

wow Now just up a few steps. (They are on the left in the picture) Gets a little steeper here - so put your toes in the holes. A few more steps to go. Finally in sight, the Teahouse! Aerodynamics (Mechanics of Flight) Tracer Bullet 00-3 Aerodynamics is the science that deals with the motion of air and other gaseous fluids, and with the forces acting on solid bodies when they move through gaseous fluids, or when gaseous fluids move against or around solid bodies. Therefore aerodynamics comes into play when air is flowing over airplanes, automobiles, cars, ships, buildings, and other objects. Aerodynamics also comes into play when air is flowing through ducts or other enclosed spaces such as wind tunnels, jet and rocket engines, and pipes.

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.

10 Strange Things About The Universe Space The universe can be a very strange place. 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.
