Are you interested in learning more about finding your position with a sextant and my slide rules? Are you curious how to calculate the current time based on the position of the moon? Do you want to hear me say "uhm" a lot?

You can follow along with the video with these interactive versions of my circular slide rules. Drag the wheels around, click on the center of the pointer to rotate it horizontal for easy reading: https://osresearch.github.io/sunwheel/rule.svg and https://osresearch.github.io/sunwheel/haversine.svg
