Ancient Navigation: How People Learned Earth's Geometry

Bob the Science Guy works through the geometry and real-world measurements behind the claim. Maps, angles, distances and observations are used to compare predictions with what actually happens.

$The Mathematics of Navigation- Standard Corrections To deal with curvature of the earth the effects of refraction, there are standard corrections that need to be made from the raw sextant readings to get a usable angle for celestial navigation. In this episode we outline those corrections, how they are applied, and what they do. Remember to hit Like and Subscribe, your support of this channel is appreciated.

In this video, I examine Live- Satellites in Orbit! using signals, orbital mechanics, and observations that can be independently checked. Hey Everyone- I just thought it would be fun to have a look at some satellites in orbit tonight. Lets go satellite hunting....
