Finished Quantum: a guide for the perplexed

Yesterday, I finished reading 'Quantum: a guide for the perplexed' by Jim Al-Khalili. It is aimed at those without a physics background, more so than Gribbin's Quantum Cats book.  There were items which I needed further explanation from Youtube such as decoherence and Heisenberg's Uncertainty principal.

I particularly liked the final chapter which deals with practical applications of quantum mechanics in areas of computing, medicine and biology.

Now that I have a firmer background of the subject, I will restart Gribbin's book again.
