A clay tablet from 3700 years in the past is rewriting Trigonometry as we know it...  That's what this weeks episode is about, a small clay tablet from Ancient Babylon, the information it contains was deciphered by an Aussie team led by Dr Daniel Mansfield...  The Trigonometry that is recorded on the tablet predates the Greeks by 1500 years, it simpler and more accurate than what we use today...  Just a short one this week that I had to share with you all, enjoy.
