Codes, genetics and puzzles

Some book recommendations, for those who like Math and the Sciences.

  1. The code book, Simon Singh.

It tells the story of cryptography, from the beginning to the present day.

Especially interesting is a detailed description of how Enigma worked. Enigma was the German encryption device in World War II, and was considered to be uncrackable.

A group of English scientists, including Alan Turing, managed to decipher the Enigma, giving the allies a huge strategic advantage (they were able to have confidence that D-Day would go smoothly, for example)

  1. The stuff of life, a graphic guide, Mark Schultz.

I really like the power of comics, to simplify and visualize complex themes.

The book is a fun introduction to genetics, including Gregor Mendel, Charles Darwin and the famous DNA double helix, discovered by Watson and Crick.

In the same line, The Cartoon Guide to Chemistry, by Larry Gonick:

  1. Math Hysteria, Ian Stewart.

Mathematician Ian Stewart is the author of several popular books on mathematics.

In this book, he describes some puzzles in great detail. The level is very high, they are difficult puzzles.

An example is the “Squaring of the Square”: how to cover a square with smaller squares, of different sizes?

Since the “squaring of the square” is too difficult a problem, I attacked the “squaring of the rectangle” in the following link.

Have fun!
