If you are like me and curious novice in quantum and relativistic physics, the "Song of quantum" (Ortoli, pocket) can be an excellent appetizer before moving to this beautiful briquette 800 pages, however, easily digestible and often exciting. I was particularly impressed by the description of an experiment known as the "delayed choice quantum eraser" which challenges our perception of space and time in a very disturbing way. Guaranteed dizziness. It will also include a description of the physics of strings (and associates), which also will be consulted in a critical enlightened "No more physical" Lee Smolin. Finally, the followers that the mathematical formalism does not reject can try on "Quantum Mechanics, Aslangul" but there must be a solid understanding that we can study in works such as "Mechanics: Lagrangian formulation of the Hamiltonian chaos , Gignnoux "courses or books or Messiah Feynman style for example.
