The way matter changes its state is through emission or absorption of light quanta, the so-called photons. Things around us are exchanging photons between themselves in a continuous, unstoppable chain of interactions. This is what makes the Universe alive. This book guides the reader to understanding how matter and photons are described in quantum mechanics as well as to mastering their interactions.
