Eureka! 81 Key Ideas Explained By halcamdad on Sep 19, 2007 - Updated Oct 15, 2011

This is a great compilation of synopses of salient concepts in the disciplines of philosophy, mathematics, science and economics. The author does a phenomenal job of explaining the concepts on a level appropriate for the educated lay reader.

Some of the concepts I found interesting were: Gresham's law, Laissez Faire Economics, the invisible hand the Pythagorean theorem, Archimedes' Principle, Newton's laws, the Copernican heliocentric theory of the solar system, Occam's razor and many others.

Even if you're familiar with the gist of the concepts covered in the text, the tales of the indivuduals involved in formulating the ideas and the historical pretext are fascinating. Additionally, it's interesting to learn how the concepts evolved from birth to being accepted in mainstream academia.

Good read.
