### Introductions

List of
physical theories that will progressively link to other
pages presenting each theory.

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)

### Expositions of specific theories

#### Special relativity

Special
Relativity theory: Minkowski geometry (improved in autumn 2016 but still incomplete, will
need more developments on geometry; relativistic mechanics not written yet)
Principle of least action (draft)

Conservation laws (stub)

Comments on the Lagrangian
of the electromagnetic field

For a logical transition from relativistic mechanics to statistical physics and
quantum physics I would see good to insert a study of Symplectic geometry.
A good book I know on the topic is *Structure of dynamical systems*
by Jean-Marie Souriau (also in French).
#### General relativity:

#### Concepts of entropy

#### Quantum physics

#### Other

Tensors.

problems (for now just one thing about gravitation)
