Measure Earth’s Rotation by Tracking Weight With Latitude @BobtheScienceGuy

Uploaded December 2021 | Updated September 2026, 3 weeks ago

A precision-scale field experiment measures the same calibrated masses while traveling between Michigan and Florida. Apparent weight decreases toward the equator and increases toward higher latitude in close agreement with the rotating WGS84 spheroid prediction, providing a direct test of the centrifugal contribution to effective gravity.

$Live Telescope with Bob Tonight we bring out the Meade 10 inch SCT, after several days of testing it is working very well, capable of more than 4 min exposures without star trails, and is perfectly focused. We have about 2 hours of clear skies so lets see some cool stuff! I want to thank my subscribers, patreons, members and those that have supported the channel with PayPal for making this possible. Info on the equipment: Optical Tube- Orion EON 110mm Refractor Mount- EXOS2-PMC Finder and Guide- Optical Finder Scopes, Optical Guide Scope Cameras- ZWO294 (Main) and ZWO 120 on the guide scope Special Thanks to Judy, Ron and Rob for their exceptional support of the channel.

$Live Telescope | Discord Chat Once again, well have a look at some satellites and the moon. Unlike last night, we are doing this with voice chat on discord. Click https://discord.gg/QwcFct7DWc to join the discord and look for us in Mt. Wolfie. We might get ambitious and try to hit some moving satellites in real time. Ive not been able to do this yet but well see if the Astronomy Gods are with us. Stop by for a chat.
