Primes that can be written as one less than a power of two, i.e 2^n – 1 for some n, are known as Mersenne primes after the French monk Marin Mersenne who...

Computer Chess: How It Thinks!

Chess requires intelligence and thought process, so how can a computer possibly do it?

A computer that is playing chess is not "thinking." Instead, it is calculating through a set of formulas that makes it to take good moves. As computers have gotten faster, the quality of these calculated moves has gotten better. Computer chess calculators are now the best chess players on the planet, even though they do it totally...


Mathematician, Edward Belbruno, says he's made the calculations to use ballistic capture to bring spacecraft to Mars more cheaply and safely than ever before.
Spacecraft usually enter orbit around planets via Hohmann transfer, which requires engineers to send the craft to its target just when the target (that's the moon, Mars, or any other planet) is coming by. Once the craft meets its target, things really get into action.

New frontier in error-correcting codes -- ScienceDaily

Error-correcting codes are one of the glories of the information age: They're what guarantee the flawless transmission of digital information over the airwaves or through copper wire, even in the presence of the corrupting influences that engineers call "noise."
