Now why didn't I think of that?

Computer Program Self-Discovers Laws of Physics

In just over a day, a powerful computer program accomplished a feat  
that took
physicists centuries to complete: extrapolating the laws of motion  
from a
pendulum's swings.

Developed by Cornell researchers, the program deduced the natural laws
without a shred of knowledge about physics or geometry.

The research is being heralded as a potential breakthrough for science  
in the
Petabyte Age, where computers try to find regularities in massive  
datasets
that are too big and complex for the human mind. (See Wired magazine's  
July
2008 cover story on "The End of Science.")

"One of the biggest problems in science today is moving forward and  
finding
the underlying principles in areas where there is lots and lots of  
data, but
there's a theoretical gap. We don't know how things work," said Hod  
Lipson,
the Cornell University computational researcher who co-wrote the  
program. "I
think this is going to be an important tool."
