Get From Eternity to Here instead

These lectures were OK but they were almost completely a not as good rehash of the materials in the professors book From Eternity to Here. The book was quite good but took a few shortcuts describing entropy that made it difficult to fully understand. The lectures take even more shortcuts. There is not much point to the lectures after reading the book. Other than that, the lectures are pretty good, but the structure of the book is better and more carefully presented. So, get the book instead. If you like repetition, then do the lectures before the book.

Awesome!

Very well spent time learning about the physics of Time. The narration was excellent and the scientific concepts very accessible for a non-scientist.

Making an is not as easy as it seems.

Physics is no easy subject, at least to me. Quantum theory harder still. However the author does a terrific job making theoretical physics accessible for the regular person. On top of that, there is just so much interresting stuff in this book that it is almost impossible to get everything in only one listen, specially while you are driving. I'm planning to listen it at least once again.

It is a book for those people who like me are absolutely fascinated by physics but just don't get what does those weird equations mean. If I had a teacher like that on high school I would probably had studied physics on college.. but you don't find teacher like him on highschools. =( It is the first time I can say I understand what entropy really is. I read many times on wikipedia and other books, and I thought I did understand, now i know I do.

There is still a long way to go before humanity is able to fully grasp the misteries of the big bang. And maybe the future that looks rather bleak may have a way out, to survive the end of the universe... hopefully

More about entropy and less about time.

What made the experience of listening to Mysteries of Modern Physics: Time the most enjoyable?

He gets very very technical and detailed. I got a lot out of each lecture.

What was one of the most memorable moments of Mysteries of Modern Physics: Time?

I appreciated that he deconstructed this idea of the "laws of physics" being absolute. The second law of thermodynamics in particular.

What about Professor Sean Carroll’s performance did you like?

Great lecturer. Has an engaging way of speaking and he prepared these lectures in a very accessible way.

If you were to make a film of this book, what would the tag line be?

Time is not what you think.

Any additional comments?

I said above that it's more about entropy than time. But, in the first lecture he points out that entropy is the best way to think about time. And he carries this through all the way to the end.

This was the most dense of the Great Courses Lectures I've listened to so far. Probably worth a second and third listen. You will get a lot out of it.

Fascinating topic, but needs editing

Would you consider the audio edition of Mysteries of Modern Physics: Time to be better than the print version?

N/A (I have not read the print version)

What did you like best about this story?

The coverage of the material was well done. It is a fascinating topic to begin with, and the speaker clearly knows his field. He presents many aspects of time, and provides the listener with an intriguing journey. Furthermore, his style of speaking is entertaining and engaging. You won't be bored!

Have you listened to any of Professor Sean Carroll’s other performances before? How does this one compare?

I have not listened to any of his other lectures.

If you were to make a film of this book, what would the tag line be?

N/A

Any additional comments?

I had two difficulties with these lectures. The first and least important is that the presenter seems to be speaking, rather than reading, which is fine--except that he makes frequent grammatical mistakes so that his sentences sound sometimes unprofessional. He would have done better to have written everything out clearly, and then followed his notes more closely.The more substantial problem is that the presenter frequently uses the teaching style of giving what he knows to be incorrect information; not telling the listener that it is incorrect; and then sometime later (perhaps many lectures later) correcting his earlier misinformation.For example: When he first introduces entropy (one of the central themes of the lectures), he defines it as a measure of the amount of disorder (paraphrasing here). As a physicist myself, I knew that this popular idea is entirely incorrect, and was appalled that he was actually putting it out there without comment. Sure enough, roughly 10 lectures later he provides an entirely different definition of entropy (the correct one), and tells the reader that what he said before was not correct. I consider this method of teaching to be at best unfortunate, and at worst inexcusably sloppy.I would not say that this problem overrides all of the good in these lectures (hence the 4-star rating), but Professor Carroll should definitely know better.Summary: A fascinating topic, presented by an engaging speaker. Just don't believe everything he says, until you're sure you've reached the end!

Smooth like coffee and cream

Dr Sean Carroll has obvious and full command over the subject matter, and I like a guy who's upfront about the limitations of his field and pet projects. Awesome course.

One small hint for listeners, as I struggled with this until the final chapter... when he says the process of mixing coffee and cream is literally irreversible, he's not talking about the ability to unmix the particles, which IS physically possible. Rather, he means the actual macroscopic event of you mixing coffee cannot be undone in reverse. With that, enjoy your coffee and cream. And enjoy the course!

great book

if you are debating whether or not to get this book, just do it. you won't regret it. I highly recommend.

THE FOURTH DIMENSION

Time, as a fourth dimension, is a mystery that Professor Sean Carroll partly unravels in a lecture series titled Mysteries of Modern Physics. Carroll helps Physics’ dilettantes, like this essayist, broaden understanding of the mechanics of the universe; albeit at the cost of some confusion and a headache.

Carroll defines words that are commonly understood by Physics’ students and vaguely or not understood by everyone else. He defines time’s arrow, entropy, and the second law of thermodynamics. Each definition offers insight to the mystery of time.

Time remains a mystery at the end of Carroll’s lectures. Travel to the future seems a possibility but travel to the past, a logical impossibility. Carroll speculates on the idea of a multiverse from periodic reversals in the arrow of time that creates new universes from new big bangs. There is much more in Carroll’s lectures that tickle the synapses and light up dendrites of a listener’s mind.

Possibly the best Physics audio book I own

I really cannot say enough positive things about this book. The book covers Physics in a general scope (Classical Physics) and then it goes into "Modern Physics" in greater detail. I relearned things with greater clarity which helped be grasp Modern Physics theories better than ever before.

My only complaint about this audio book is that it was only 12 hours in length. I was left hungry for more. FEED ME MORE PHYSICS!!!

worth your while

In this course you will explore the physics of time, how they relate to entropy and the Big Bang, and how understanding time leads us to try to understand the nature of the laws of physics. I have read several of the Great Courses classes now, particularly on physics. Many of them repeat essentials about Special and General Relativity, the nature of quantum mechanics, dark matter, dark energy, and the forces of nature. With that in mind, they tend to cover much of the same ground. This has been a completely different course. Here we spend quite a bit of time on entropy, the big bang, and how theories on the beginning of time also has consequences for multi-verse theories.

The instructor spends a little too much time on the introduction and calendars and perhaps labors on entropy for a bit too long. But with that said, he is an engaging teacher, the subject really evolves over time, and goes places I did not expect. Really worth the time you invest in it. Hang on until the second half especially, where it gets really interesting.
