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 ...

A physics video claims rubber bands don't act like springs. But is that true? Dot Physics blogger Rhett Allain tests the notion with a few custom contraptions.

Traditionally coil springs were used for applications to exert one-dimensional force along a given spring coil axis. However, in recent years, there has been an increasing trend in using coil springs ...
