“There is no branch of detective science that is so important and so much neglected as the art of tracing footsteps,” says the fictional detective Sherlock Holmes. Now, UK researchers have developed a ...

Total internal reflection microscopy is a light microscopy technique that relies on total internal reflection of illumination light to generate an evanescent wave that extends less than 200 nm from ...

Exploring the physics phenomenon where light waves penetrate a boundary even when total internal reflection occurs. Demonstrating how these non-propagating waves exist and their crucial role in ...

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 ...
