Geometry in the Open Air

When you walk around, can you find the height of a tree or the width of a river or the distance to a passer-by? We will learn a dozen of methods for doing these estimations, with the help of simple tools made of ordinary things: a measuring tape, a string, a piece of paper, a cap, a small ruler, a hand mirror or just your own palm. Other geometric practices performed barehanded include measuring angular diameter of the Moon and angular distance between stars, and discussion of why we see the Moon larger in the evening than in the night.

This class will be delivered online via the online platform Zoom. Enrolling students need to ensure they have an email, a reliable internet connection, microphone/speakers and access to a tablet, smartphone or computer.
