Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Centripetal and centrifugal forces are central to circular motion, but they're not the same. Discover the differences between ...
