The Controversial Discovery of Irrational Numbers
TLDR The discovery of irrational numbers, such as the square root of 2, challenged the Pythagorean belief in a rational universe and led to conflict and expulsion. However, these numbers were more readily accepted in India and the Middle East, and their acceptance in Europe was solidified with the adoption of the Hindu-Arabic number system.
