Well the new channel, 'ResearchFlatMoon', is growing nicely and the new format is attracting new viewers. I thought I would give a quick update on some upcoming projects.

$The Radius of the Earth | Al Biruni Following up on our last video where we found the height of a mountain using the tangent function and a little algebra. Today we use that information to determine the radius of the earth and have a discussion of the effects of refraction. Upon review I noticed a slight error in my discussion of refraction. What I was discussing was the standard refraction of 7/6 R. Given a determination of the REFRACTED radius, to get the true radius you would divide by 7/6 or MULTIPLY by 6/7. I accidently said divide by 6/7. Sorry for the confusion.

Learning a lot of new skills- drilling metal, tapping, and solving problems. The mount is dry fit and leveling ability checked. We still need to attach the extension, drill the mounting plate (might need a machine shop to do that), tap the stud for the traversing mechanism and rig the attachment rod. If it is worth engineering, it is worth over engineering in my opinion.... Remember to hit Like and Subscribe, your support of this channel is appreciated.
