Welcome to the quantum world, where the physics of infinitesimally small particles are dominated by probability over certainty. Where mathematics and philosophy collide, quantum mechanics is considered one of the hardest yet quintessential fields in physics. From Planck to Schr dinger to Heisenberg, the nature of subatomic particles is dictated by quantum physics. The Theory of Physics, Vol. 4 not only offers a mathematical introduction, but also...
