About this ebook
Jim Al-Khalili is about to untangle the world's greatest science conundrums...
___________
How does the fact that it gets dark at night prove the Universe must have started with a big bang?
Where are all the aliens?
Why does the length of a piece of string vary depending on how fast it is moving?
Our subject is 'perceived paradoxes' - questions or thought-experiments that on first encounter seem impossible to answer, but which science has been able to solve.
Our tour of these mind-expanding puzzles will take us through some of the greatest hits of science - from Einstein's theories about space and time, to the latest ideas of how the quantum world works. Some of our paradoxes may be familiar, such as Schrödinger's famous cat, which is seemingly alive and dead at the same time; or the Grandfather Paradox - if you travelled back in time and killed your grandfather you would not have been born and would not therefore have killed your grandfather. Other paradoxes will be new to you, but no less bizarre and fascinating.
In resolving our paradoxes we will have to travel to the furthest reaches of the Universe and explore the very essence of space and time. Hold on tight.

Another interesting and introductionary written book into quantum mechanics and other sciences topics. I loved his explanations of the predestination paradox and of schrödinger's cat. All really interesting but can make the head hurt. If you've not read any of Jim start with the "guide for the perplexed" as it gives some great background and concepts which make understanding this easier. If you only want to read 1 this is the better book.
