The Mathematics of Measuring the Solar System is currently being developed as a four-part series of one-hour sessions based around the history of measuring and calculating the sizes and distances of things in our solar system, starting with Eratosthenes' attempts to gauge the size of the planet we live on and leading up to 18th Century events that enabled us to gain an unprecedented understanding of our place in the solar system and therefore the universe as a whole.
Some resources will eventually be available here for self-delivery, but options and costs for delivering to various audiences both on- and off-line can be discussed. If you'd like to have a conversation about that please see this page on my personal blog.
