An exploration of physics by dimensional analysis : telling a lot of fundamental physics and the amplitudes of diverse effects mainly by multiplying quantities. Some sections have been moved to separate pages:

The speed of light and astronomical distances

The energy of nuclear reactions ; The radius of nuclei

Electromagnetism

The gravitational constant

Effects of General Relativity

The parameters of the atomic structure

The compressibility of condensed matter

The speed of the sound in condensed matter

Temperature(to be continued)

Principle of least action (draft)

Conservation laws (stub)
