After a long time I was able to complete this book at one go as it addressed the paradoxes that science cannot answer, but yet the questions raised were from the Physics and pertained to 'reality'. Prof Al-Khalili, perhaps the first Arabian writer on 'Science writing' I have come across, has addressed the following:
Achilles and the Tortoise paradox
The Pole in the Barn paradox
The Paradox of the Twins
The grandfather paradox
The paradox of Laplace's Demon
The paradox of Schrodingers' Cat
The Quantum Chemist is sure of the last but one here. The style is lucid and pleasant and even a lay man can get through provided he evokes at least '3D' thinking. Many 'assumptions' are purely theoretical, but could be real.
Most people are nostalgic about their 'past' and this book gives you the reason to be nostalgic about the 'future'. Great efforts Prof. Khalili.
