The field of mathematics often supplies papers that demand attention even from casual observers. Here’s a new one: “Non-Squeezing Property Of Contact Balls,” Sheng-Fu Chiu, arXiv 1405.1178v1, May 6, 2014. The author is at Northwestern University. Here’s detail from the study: BONUS (unrelated): “IMPROVEMENT IN MACHINES FOR SQUEEZING PUDDLERS BALLS,” US Patent #190,385, granted to E. […]

Ball squeezing – Kick Butt™
Ethnomusicologist Dr. Verna Gillis (previously an assistant professor at Brooklyn College and Carnegie Mellon University, US), has just recently been granted a US design patent for her ‘Ball’. (Jan. 7th, 2014) More accurately named as the Kick Butt Ball™, which is described as “… a novel spin on a stress ball, with one side shaped […]
Hairy Ball Update 2012
The Hairy Ball Theorem (HBT) was first postulated (and then proved) by Luitzen Egbertus Jan Brouwer in 1912. An informal statement of the theorem is that : “One cannot comb the hair on a coconut”. Temptations to classify the theorem as trivial should be strongly resisted – as it’s still finding relevance in many current research […]
Ball squeezing and creativity
Want to be more creative? No problem, just take a ball and squeeze it (but only in your left hand, otherwise the consequences are as yet unknown). Dr. Abraham Goldstein (pictured – and who may or may not be squeezing a ball with his left hand) along with colleagues at the Brain Research Center of […]
