Beyond The God Particle by Leon Lederman and Christopher Hill (book review).

Considering what is said about the confusion calling the Higgs boson the God Particle, I’m surprised by the title, ‘Beyond The God Particle’, was used by authors Leon Lederman and Christopher Hill. However, the name is stuck in the public consciousness and I doubt if the name will change that quickly. The example of a […]

This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth.

Magnificent Mistakes In Mathematics by Alfred S. Posamentier and Ingmar Lehmann (book review).

I do think the title ‘Magnificent Mistakes In Mathematics’ needs to be qualified as ‘Magnificent Mistakes In Mathematics Made By Mathematicians’ for the first couple of chapters. If you thought those scientists, amongst them, Isaac Newton, Lord Kelvin and Albert Einstein, were perfect mathematicians then I think you’ll be pleasantly surprised by the fact that […]
