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.

Including notably schools that follows Ciro Santilli's ideas as shown at how to teach.

This is an example of how paging operates on a simplified version of a x86 architecture to implement a virtual memory space with a 20 | 12 address split (4 KiB page size).
