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
Introduction to quantum physics for
philosophers
(pdf slides, May 2019 ; assumes the above understanding of entropy) : short clarified version with
figures, of the main ideas from the below
previously written texts:
Other
Tensors and tensor products.
Solved physics
problems (for now just one thing about gravitation)
