Basically, it allows you to “plug in” a graphical analog circuit of any design into a Python script and manipulate it easily, in any way needed.

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 ...

Modeling the motion of a pendulum is often included in introductory physics courses, but it's not as easy as you think.

Both the real pendulum and the simulation mimic each others' movements exactly -- adjusting the motor affects the simulation and adjusting the parameters of the simulation affects the motor ...
