Compasses and Calipers

I'm preparing to chart the shadow of a local monument during the Vernal Equinox. It's research for the new book.

I'll also need a plunger.


  1. "Dividers" to the mariner. You are engaging in one of humanity's first and greatest (and still most fun) charting exercise: "What is that thing in the sky, and where is it going?" Stay at it!

  2. Many thanks for support how I can thank you?
