NavList:

Thanks Bill ,

I really enjoyed your lecture :)) Now please tell us what kind of very large watch is on your left wrist. 

To further complicate the triangle center- what happens to the triangle center when we attach a confidence value to each individual LOP ? I call this a "calling the shot percentage".

We videoed my talk to school students on the symmedian point and navigation. https://youtu.be/pzDyi7ANoVA. OK so the video is not so good as the projector saturates the camera - slides are added in the corner. So by now NavListers all know about the symmedian point!

I am just sharing this and all the source materials for the slides including both Euklides and Geogebra code for drawing symmedian points here on Github https://github.com/billlion/symmedian-talk, just in case any members want to make a similar (better I hope) talk on geometry and navigation!

I have given the talk a few times since and got a bit better. I pass around Colin Steele's old sextant (which I shared earlier) and they seemed to like that.
