Cute simple paper-cut stop motion animations videos by Mithuna Yoganathan, a PhD in theoretical physics at the University of Cambridge: www.damtp.cam.ac.uk/person/my332.

This has the seeds of direct good intuition, but often stops a bit too short. Worth a look though, there is value in them for beginners.

Maybe Spanish accent, but might also be from some other european language.

Very practical, low-cost experiments.

As indicated by its name, the journal contains mostly short letters sent to the editor, often 2 or 3 pages long, which allows for a faster publication cycle and dissemination of new results. This is notably useful for experimental physics.

Most important superconductor material  Updated 2025-06-17  +Created 1970-01-01

As of 2023 the most important ones economicaly were:

Nb-Ti: the most widely used one. Used e.g. to create the magnetic fields of the Large Hadron Collider Up to 15 T.
Nb-Sn: more expensive than Nb-Ti, but can reach up to 30 T.

The main application is magnetic resonance imaging. Both of these are have to be Liquid helium, i.e. they are not "high-temperature superconductor" which is a pain. One big strength they have is that they are metallic, and therefore can made into wires, which is crucial to be able to make electromagnetic coils out of them.

Planck-Einstein relation  Updated 2025-06-17  +Created 1970-01-01

Photon energy is proportional to its frequency:

e n er g y = (pl an c k s co n s t an t) * (f re q u e n cy)

(1)

or with common weird variables:

E = h * ν

(2)

This only makes sense if the photon exists, there is no classical analogue, because the energy of classical waves depends only on their amplitude, not frequency.

Experiments that suggest this:
