I read Schrödinger’s Cat by John Gribbins quite a long time ago now and enjoyed it so much I immediately bought the sequel, Schrödinger’s Kittens. It has spent much of the intervening time sitting on my bookshelf looking tricky.
Schrödinger’s Kittens brings the progress of quantum physics up to the mid-nineties. I was very conscious while reading it that it was twenty years old and the field has moved on considerably since it was written. Recommendations for recent books on the subject would be most welcome – preferably written for someone who barely passed GCSE physics.
The book takes the cat in a box thought experiment and pursues its implications through logical extension. It discusses what that means for what we know about our world. Which is basically not nearly as much as we’d like to think. I found that Schrödinger’s Kittens was not quite as accessible or engaging as Schrödinger’s Cat. It may be worth a read, depending on just how thorough your reading in the subject is, but there are probably more up-to-date books out there.
