Suppose you are getting ready to take a physics test. Everything is set—but wait! Your calculator battery died. What do you do? If you're extra crafty, you could grab an LED (light-emitting diode) and ...

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 ...

Experimental device harnesses quantum properties for efficient processing at room temperature. Engineers are working to ...

Kai Sun of the University of Michigan is a humble physics professor with ambitious goals. "I'm mainly a paper-and-pencil type of theorist, doing analytical calculations mostly," Sun said. "My ...

Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...
