Publisher's Summary

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these twenty-four lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. After that, you'll follow along as Professor Wolfson outlines the logic that led to Einstein's profound theory of special relativity and the simple yet far-reaching insight on which it rests. With that insight in mind, you'll move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time.
From there, you'll embark on a dazzling exploration of how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so profound and so at odds with our experience that it nearly defies language.
By bringing relativity and quantum mechanics into the same picture, you'll chart the development of fascinating hypotheses about the origin, development, and possible futures of the entire universe, as well as the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. But the goal throughout these lectures remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson.

Great primer for hard SF fans and physics laymen

I was a little ambivalent about trying one of these "Great Courses" on audio, especially with references to diagrams and such, but the instructor promised at the beginning that you could follow along at home without needing the pictures, and he was right, though there are points at which it might benefit a listener to pause the the lecture long enough to look up the diagram if you are having trouble visualizing what he describes.

This is a course on advanced physics for people who are not physics students. All that high-level stuff like General and Special Relativity, the three fundamental forces, quantum mechanics, why nothing can go faster than light, how time dilation works, what is really going on with black holes and whether "wormholes" really exist (answer: there is currently no actual evidence of them, we just know that the math supporting the possibility of their existence works) and a dozen other topics for any long-time science fiction reader.

And that is why I downloaded this course, because I haven't had a physics class since high school, and I've had only a brief survey course on quantum mathematics, but I wanted to understand the physics behind relativistic travel and the formation of the universe and quantum theory and all that jazz well enough to feel educated when I read science fiction that tries to be "hard" (and even to have a better grounding for any SF I might write myself...).

I would say this course works very well for that purpose. The professor promises that the math is minimal, so at several points he handwaves the formulas, saying "Trust me (but go look it up if you want to really understand it)" but assures us that the concepts he explains require no more than high school algebra, for the most part, and this was also true. So this is a very "math light" physics course for non-physicists, and thus for someone who is a veteran of hard SF there won't be much here in the way of new concepts - you have probably read Heinlein's Time for the Stars in which a pair of telepathic twins conduct the famous "twin experiment" with one twin staying on Earth getting old while the other twin sets off on a journey in a spaceship traveling at near-lightspeed. And you've read lots of stories about black holes and how they "slow time" as you approach the event horizon. (Go see Interstellar - it's a fantastic movie.) And you know that pure matter-energy conversion would be a billion times more efficient than nuclear fusion, if we could do it. And you've heard of Schroedinger's Cat and how supposedly we could use paired qubits to achieve faster-than-light communication (we can't). And gravity warps time and space, and light is a particle and a wave (and in fact so is all matter, really), and Einstein refused to believe God rolled dice with the universe.

All that is covered here, and at the end of it, you'll understand it better, conceptually, but obviously this cannot replace an actual physics course and if you want to really, really understand it, you'd have to actually get deeper into the math. I now have a better understanding of what physics says about General and Special Relativity and black holes and time travel and quantum entanglement. Do I really, thoroughly understand it? You'll probably find several points Professor Wolfson covers need to sit with you awhile, and some stuff you'll really have to read more deeply to fully "get it." But you can get the gist adequately from this course.

So, this course will not work as a substitute for taking an actual physics class. It probably won't even work very well as a primer. But if you're just a layman who already has some idea of the stuff you've been reading about in science fiction but you want to know more about it, you'll find this course quite valuable, and if you actually don't know any of this stuff, it will probably blow your mind.

The lecturer builds up his topics very carefully, starting with what ancient astronomers and physicists knew, all the way back to Aristotle. There is a lot of physics history here, so you'll get your Copernicus and Galileo and Newton and Maxwell and Bohr and of course Einstein, and that part is also quite interesting, as there is just a little bit of biographical information about each person, but more importantly, what exactly they figured out and how and how it changed what was known up to that point in time.

Overall, well worth the investment in listening to.

I enjoyed this a lot more than I thought I would

I admit up front that I have a strong interest in this topic (relativity) but have only recently tried to better understand it. Professor Wolfson does a terrific job of keeping the explanations simple and easy to understand. He moves along quickly, so the listener needs to stay focused. But I really enjoyed listening to this and professor Wolfson makes it easy to listen to. If you want to have a basic understanding of relativity, this is a great audio book to start with. I strongly recommend this.

Pitched at just the right level, very engaging.

I've always rather regretted dropping physics at the age that I did, but assumed that my lack of advanced mathematics was probably a barrier to investigating the subject further by myself. I'm ecstatically happy to be proven wrong.

I couldn't really be happier with this course. It seems to be pitched towards an undergraduate non-scientist level, which is to say that it assumes that you don't know any physics already, but *does* assume that you have a few brain cells to rub together. So far so perfect.

The content is no doubt simplified and focused on the conceptual (Advanced physics without maths? How could it not be?), but Professor Wolfson is superb in how he takes the listener through the evolution of various theories in engaging logical steps.

NOTE: There are references throughout the lecture series to occasional diagrams and course materials, which are *not* available for Audible customers to download form the Great Courses website. A quick google search however will usually provide you with similar diagrams if you just throw in the relative topic keywords.

Enjoyable and informative, but...

An enjoyable telling of the story of how the physical world works, which should prompt anyone to look for more, not least to look further into the mathematics underpinning it all. The lecturer speaks enthusiastically and quickly and sometimes loses track (entertaining in itself) but topics are well paced and points are repeated and reinforced so you don't have to continually backtrack if your attention strays. Unfortunately this offering is purely audio, with no apparent links to important supplementary visual aids (even the most basic diagrams and equations) which would be available if the audiobook was purchased from the original producer.
This is simply wrong and unfair never mind the (usual) claim that they arent necessary given at the beginning. I'm writing this having studied these topics at undergraduate level - I feel that others are missing out. But as I said in the end it should encourage anyone to look for more elsewhere, which can only be a good sign.

I probably need to listen to it a few times

There are obviously a lot of very complicated ideas I'm this audio book. You'd definitely need a basic understanding of science to grasp it... but it does a good job of explaining special relativity simply. Quantum physics and general relativity I will need to re listen to!
