Great Ideas in Physics

by Alan P. Lightman

Described by one reviewer as a future literary rival to Sagan and Hawkins, Alan Lightman has written a text for liberal arts students that promises to have a far reaching effect on the way the course is taught. The book is intended for the freshman-/sophomore- level course at liberal arts schools. Lightman presents four ideas of The Conservation of Energy, The Second Law of Thermodynamics, The Relativity of Time, and the Wave-Particle Duality of Nature (Quantum Theory). The two basic aims of this book are to provide a grasp of the nature of science and to explore the connections between science and the humanities.

A very cute introductory book about some of the most intriguing "ideas" of modern physics: the conservation of energy, the second law of thermodynamics, the special theory of relativity, and quantum mechanics (wave-particle duality and Heisenberg's uncertainty principle).

These subjects are treated at a pretty basic/introductory level (last year high school/first year Uni), and they are a bit too light from a mathematical perspective for my taste, but they are explained quite precisely from a conceptual perspective. There are a couple of inaccuracies, but nothing dramatic.

A pleasant, very readable, well written easygoing book,with nice examples and clear explanations. The "derivations" of the Heisenberg uncertainty formula and of the Lorentz factor are quite nicely explained.

I actually enjoyed this. it's a textbook really but you only need to do the math if you just can't stand not knowing. It helps if you've read a bit about quantum physics but not requisite.
There is a lot of math - and it my case it helped me understand how it works a bit more. Thumbs up.

The conservation of energy, the second law of thermodynamics, the theory of relativity and quantum mechanics. Physics for average Joe. Simple, but beautiful examples. If you want to polish your college physics, or understand how these theories work in the simplest possible way, this book is for you. One of the best explanations of wave/particle duality and Heisenberg uncertainty principle.

Great Ideas in Physics: Conservation of Energy, Second Law of Thermodynamics, Special Relativity, Quantum Mechanics, Alan Lightman (1948-), 2000, 300 pages, ISBN 0071357386

Plays fast and loose with the double-slit experiment, pretending that a "transparent detector" can detect a photon passing through a given slit, yet let that same photon continue, to hit the screen beyond. No. A photomultiplier absorbs a photon and gives out an electric current. Goes on to claim that what happens depends on whether someone is trying to observe it. No. A quantum propagates as a wave and interacts as a particle. The photon or electron travels by all possible routes, yet always hits only a single molecule of silver nitrate, darkening a single spot on the plate. It's the interaction of the radiation with matter that changes the wave into a particle. Not the mind of the observer.

Good simple derivations of the Heisenberg uncertainty principle, and of the time-dilation and length-contraction formulas, but fails to explain how the stationary observer can detect the ticking of the moving clock.

Defines temperature as average thermal energy /per molecule/. Not quite. It's average thermal energy per degree of freedom. https://en.wikipedia.org/wiki/Degrees...

You know, I'm not a dummy. But this book gave me the equivalent of an intellectual wedgie. It made my brain hurt, and I certainly wanted to bin it before I finished it. I'm glad I completed the read, but that probably says more about my inbuilt sense of literary masochism than it does the author's sense of purpose.

The book aims to tackle a couple of the Big Ideas in the field of physics - the conservation of energy, the second law of thermodynamics, the theory of relativity and the idea of quantum mechanics - to give readers an overview of some of the main struts of the whole shebang. Lightman's an amusing enough kind of guy - his style is easy and conversational - but if you suffer from formulae dyslexia you'll want to give this one a miss. I found I could handle the descriptions and the analogies, but when it went into hard equations I was lost.

To be fair, the book is structured to minimise this kind of befuddlement - there's even a primer in the appendices (which also include class guides, which would be handy for some) - but even though it's an introduction, the absolute layman can find it a bit of a drag.

I love Lightman's other work - Einstein's Dreams is a favourite - but this one was a bridge too far for someone as mathematically retarded as I. I'll soldier on with others in the field, though, as books like this (and Feynman's work) certainly pique the curiosity of even the most ardent of us Arts grads...

You will learn about both big names and some little known names in the world of physics. Laws of energy, units of mass, length, and energy are discussed. This book might be good for teachers that would like to cover a little history as they explain some of the concepts.
