Mathematical breakthroughs!!

Lots of interesting things are happening in the Math world. Some of the remarkable breakthroughs this week:

• Computation of Pi. Mathematicians Alexander J. Yee & Shigeru Kondo have successfully completed the computation of Pi to Five Trillion digits. The computation took 90 days on a single desktop. This is a new world record. The previous record was computation up to 2.7 Trillion digits. Link.
• Rubik’s Cube solution. A team of researchers found that every possible combination of the Rubik’s cube can be solved in 20 moves or less. There are 43,252,003,274,489,856,000 possible Rubik’s cube positions. This is a new world record. The previous solution solved the problem in 28 moves. The number of moves used to solve the Rubik’s cube problem is known as God’s Number. Link.
• P != NP. Researcher Vinay from HP labs claimed proof that P != NP. However, a major (unfixable) flaw was found later on his paper.
