IBM At the Hot Chips 2010 conference, IBM announced their upcoming z196 CPU, which is really, really fast. How fast? Fastest chip in the world fast. Intended for Z-series mainframe computers, the Z196 has a clock speed of 5.2GHz. Measuring just 512 square millimeters, the Z196 is fabricated on 45nm PD SOI technology, and on its surface contains almost one and a half billion transistors. My... Processor is bigger than yours.

brain is not very good at precise calculation of physic processes

Then how can one shoot a basketball? The brain is very well adapted at simulating physics.

So well-adapted that it believed for a long time that the Sun was gravitating around the Earth...

Before science was widespread, that seemed like a pretty good idea. There was no reason to believe otherwise. It's not like universal gravitation is obvious - we only ever see things falling toward the Earth.

And technically, space isn't absolute. The Sun really is orbiting the Earth just as much as the Earth is orbiting the Sun. We only consider the Sun to be the center because it is bigger.

from experience?
imprecisely. (only to the precision needed)
also, the game is designed/evolved to the game players abilities, and demands of entertainment. (though I don't know much *how* that influences the mind's ability to make musculoskeletal etc system shoot baskets)

Still, it takes quite a lot of precision. First your brain has to measure the distances to the nearest centimeter using the information from your eyes. Then you have to figure out exactly how much to flex each of the muscles involved. Then your brain has to actually send all that information to your muscles. And your muscles have to follow it accurately. All in less than a second. It only seems simple because it natural to us.

Try creating a robot that can do that. Even with near perfect physics simulation, you'd have a very hard time.
