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.

Photon energy is proportional to its frequency:or with common weird variables:

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:

Basically a synonym for Lie group which is the way of modelling them.
