Quote for the day:

"We have, over again, the fact that criticism of the mathematicians procedure, if it wishes to be relevant, must be based on thorough sympathy and understanding." - Phillip E.B. Jourdain

the tiling of the plane presents more geometrical problems and discoveries

 

"In other words: It's possible that that there are dozens — hundreds, thousands even — of these convex pentagon shapes waiting to be discovered. Up until last month, only 14 had been found, and for all anyone knew, that list could have been final."

 

"But last month, a cluster of computers that Von Derau was using to run though different shapes spit out an intriguing possibility."

They spent two years searching for this with an algorithm they made.
