Learn how to determine the observed intensity of a supernova using core physics ideas like luminosity, distance, and the inverse-square law. This video walks through the reasoning and calculations ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Here is classic (and difficult) physics problem that poses an interesting question: Take two points in space, Point 1 and Point 2. What is the path from point 1 to 2 that a frictionless object could ...

In a previous article, I introduced the recent open-sourcing of quantum computing software by DWave. DWave is the maker of a quantum computer being used and studied by a number of groups, including ...

Moving along with our top science apps (we first showed you the best iOS math apps), now it’s time to clear some of the mystery surrounding the great laws of physics. These have plagued students ...
