V. A Conversation about Quantum Mechanics
Reckoning with uncertainty; a beginners guide to physics at the smallest scale Familiar quotations “Quantum mechanics is very impressive. But an inner voice tells me that this is not yet the right track. The theory yields much, but it hardly brings us closer to the Old One’s secrets. I, in any case, am convinced…

IV. Summary of Thermodynamics and Statistical Physics
An Introduction to Some of the Basics Thermodynamics is concerned with heat (thermos), movement (dynamics), and work; all are forms of energy. During the industrial revolution beginning in the 18th century, engineers started examining heat as a source for movement and work … replacing draft animals, wind, and waterfalls. Classical thermodynamics began by pondering only…
