All about Numeral: the Logical Brain Cell key chain
• Archimedes of Syracuse (287-212 BC), the Greek mathematician, astronomer, and engineer, calculated the lengths of the sides of two 96-sided polygons, one inscribed just outside a circle and one just inside, and determined that the value of pi was between 3 1/7 (or 3.14286...) and 3 10/71 (or 3.14085...). He also figured out how to tell if a crown was made of impure gold by immersing it in water. Eureka!
• Zeno’s dichotomy paradox says that if it takes some time to travel successive half-distances to a destination, it must take an infinite amount of time to get anywhere — so motion is impossible.
When the philosopher Diogenes heard the paradox, he disproved it by standing up and walking away!
