Science Lesson on Autocratic Rule
There is an immutable law in physics, the second law of thermodynamics, that any isolated system not receiving the input of energy (work) from the outside will tend toward states of greater disorder. Examining human history, one might suspect another immutable law: that societies will progress to autocratic rule if there is no effort (work)…

Where Physics and Biology Intersect
Life and the Second Law of Thermodynamics Life is orderly, contrasting the second law of thermodynamics, which states that systems naturally become more disordered over time. A few examples of the second law are that sandcastles erode, leaves scatter, perfume evaporates, a cup of coffee and the universe cool. Despite this law, living organisms maintain…

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…
