comment What axiomatizations exist for special relativity?
Dear Gustavo. It is usually frown upon to directly copy-paste identical answers. (The problem is if everybody start to copy-paste identical answers en mass.) In general in such situations, please consider one of the following options: (i) Delete one of your answers. (ii) Flag for duplicate posts and delete one of your answers. (iii) If you think the two posts are not duplicates, then personalize each answer to address the two different specific questions.

Suggestions to the question (v2): 1. Remove duplicate questions 2. Ask only one question. 3. Besides Riemannian manifolds mention Lorentzian manifolds to include relativistic theories.

comment How can individual photons have different amounts of energy?
This question (v2) seems spurred by a confusion between rest/invariant mass and relativistic mass. See e.g. this Phys.SE post, and a couple of paragraphs down on this Wikipedia page.
