Earth is a crazy place. Figuring out its size and shape took a very long time, which seems even crazier to people living in a time of overwhelming access to knowledge, and the technology to gain and share it. Poor Eratosthenes. Maybe if he'd gotten out of his armchair once in a while, he might have been able to discover--and enjoy--more of this amazing planet. (Note: The link on "Eratosthenes," above, points to the Carl Sagan video we watched in class.) Please review the slides below. And cut up some round fruit for someone! Use it to try to explain the geographic grid.
Which brings us to the lab. Although the lecture went well, the lab was more time consuming than planned. A remedy is forthcoming.
See you in class.
