Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

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 ...

Recent progress in the fields of magnetic circular dichroism (MCD) and magneto-optical rotatory dispersion (MORD) is reviewed and these techniques are contrasted with those of natural circular ...

Electric and magnetic fields are both components of an electromagnetic field. These two components occupy different planes relative to the cause of the electromagnetic field, for example a moving ...
