Physicist Elmer Imes’ careful work to capture the spectra of molecules made clear the worth of the theory of quantum mechanics. Shine a beam of white light through a chemical sample, then send that ...

Seven vibration-rotation bands of nitrous oxide have been measured with high resolution. The rotational fine structure of each has been analyzed and rotational constants have been derived. The value ...

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 ...

Kyoto, Japan -- Humans may never be able to tame the Sun, but hydrogen plasma -- making up most of the Sun's interior -- can be confined in a magnetic field as part of fusion power generation: with a ...
