Gleiser's Latest



For the cosmology readers out there, a couple of Web reviews of physicist Marcelo Gleiser's latest book, "A Tear At the Edge of Creation" below.

(This is Gleiser's account of his journey from string theorist and unification seeker to a totally different and "radical" view of the nature of the Universe, wherein a "Theory of Everything" is likely not achievable.)

"...craziness has a fine history in physics"

...so says a NY Times piece on the start-up attempts for the Large Hadron Collider, and a new theory pushed by some that the device is doomed or at least jinxed, by the very Higgs boson for which it is searching... this is cosmology gone wild... but, hey, that's almost the normal state for cosmology, so read all about it:

"The Age of Entanglement"

Don't know when I'll find time to sit down myself and read the 400+ pages of "The Age of Entanglement: When Quantum Physics Was Reborn" by Louisa Gilder (here and here), but feel like I shouldn't delay any longer citing it on this blog.The book (8+ years in the writing) has been receiving generally excellent reviews around the bookworld; especially excellent for a first-time author; especially
