Starting on the curvature of the world.

Maths can be a great escape that has pragmatic purposes in our lives. A lot is unknown and many worry greatly about where we are headed but that does not mean we should stop our pursuits of knowledge. The opposite is more true in direction. We really must be challenging ourselves to learn more with rigors of definition.


How does one measure the radius of the Earth? People have known a fantastically accurate value for far longer than may make sense to many of us today.
Since radius and circumference are in a pi-portion to each other, if we know one, we know the other. It turns out, one of the great questions of maths peoples throughout history is to identify the size of the Earth.
Eratosthenes is one of the dope names of all times. Say it one time fast…Anyway, he is attributed to the earliest accurate measure and it was down with sticks, rope, and a lot of walking.
