jan 1, 297 BC - Euclid

Description:

Euclid found out that light travels in a straight line, he did this by using a mirror and shining light on it and he noticed that the angle the light was shined onto the mirror is the same as the angle that it is reflected.
There is no real flaw to this discovery
