Scientists from Stellenbosch University in South Africa have designed a new gravity energy storage system, based on linear electric machines (LEM), that could be used in decommissioned mines. “The ...

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 ...
