NASA Says Asteroid Will Buzz Earth Closer Than Many Satellites 225
coondoggie writes "NASA says an asteroid about half the size of a football field will blow past Earth on Feb 15 closer than many man-made satellites. NASA added that while the asteroid, designated 2012 DA14, has no chance of striking Earth. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet."

A soccer field doesn't have any size defined. It's just "between 90 and 120m" long and "between 45 and 90m" wide. So btw the smallest and biggest field, there is almost a factor of 2.7 in area. That's a bit of a margin!

Martial Arts is a broad term, and most people (like you) only pay attention to the "Martial" part. The Style that Chuck specializes in and teaches in his schools is focused on rigid adherence to the traditional Forms, and application of mental Discipline. They are as well-suited to an open fighting situation as disciplines classified as Fighting Styles, which is why you don't see people using pure forms in competitions like the UFC... winners often have a background from a variety of styles which is why they are called "mixed martial arts" competitions.
Not to say that people like Chuck and Bruce Lee aren't pretty mean fighters, anybody with that much training is not going to be an easy mark. But I'd put almost anybody who fights in the large UFC competitions against a pure style fighter any day, especially if they aren't in a ring with time limits and rules.
Having said all that, it's important to note that Chuck, Bruce Lee, Jackie Chan, and other popular film fighters have to slow down most of their moves so the audience can follow the action, and what they actually do on screen are sequences and styles you wouldn't ever actually use in real life combat. Many of the "moves" they display for the camera are not actually combat moves, but rather are meditative Forms designed to build endurance, focus, and strength.
