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 standard time crystal is a new phase of matter that features perpetual motion without expending energy. According to Chong Zu, an assistant professor of physics at Washington University in St ...

Three-dimensional time is a theory in which time, like space, has multiple independent directions—typically imagined as three axes of time motion, similar in concept to the spatial X, Y and Z axes.

By proving how individual molecules create the complex motion of fluids, three mathematicians have illuminated why time can’t flow in reverse.
