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.

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!

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.

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

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.

Mixing Milk and Coffee - Entropy At its Best!

If you could sum up Mysteries of Modern Physics: Time in three words, what would they be?

Worth the ... TIME!

(1, 2 ... 3 - yes, looks about right)
(Audible, could you please come up with even more stupid questions?)

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

Let me ignore Audible's blabla for a sec and try to say it with my own words:

Sean Carroll really manages to take even the layman (I am from the philosophical side of science) on a tour through classic physics up to more or less the most modern theories about what's "the kernel of the brute". Pace of the lectures, examples and even the honest outlooks on what "we don't know" are one great inspiration for the mind.
Mr. Carroll describes several ideas about how our universe may have come into existence, how the "Arrow of Time" (time always going into one direction and not being reversible) works and why it is there. He does not pretend to have an answer, but gives a nice kaleidoscope of working (and not so working) theories. On sidelines he gives some basics about Quantum physics, the differences to classic physics and ... lots of stirring up milk in coffee to test entropy.

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

So far I haven't listened to any other of Mr. Carroll's "performances" (Audible, PLEASE rethink the phrasing of your questions, this typing-in of comments is making me feel like a complete idiot).
But the good feeling I have after listening through this course, the believe that I "got it", or at least some of it, makes me think: "Gimme more, Mr. Carroll!"

Was there a moment in the book that particularly moved you?

What really "moved" me is the fact that - although I don't claim to have understood everything - especially not why anyone would actually pour milk in his coffee! - it feels like I have some "vocabulary", to say the least, from the world of Quantum Physics. That's surely not the worst one can say about listening to an audio book. What's next? Rocket Science? Understanding Women?

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.

Atheist Agenda

What would have made Mysteries of Modern Physics: Time better?

More science, Less bashing of philosophy and religion.

Would you ever listen to anything by The Great Courses and Sean Carroll again?

Never. I listen to a lot of science lectures. There was good science there, but he has an agenda that he wears on his sleeve and it is wildly inappropriate. I felt like he was regularly considering me an idiot. I am not a zealot, but he is.

Any additional comments?

If you are at all a free thinker, avoid this. This is agenda riddled and insulting. Even if you are not faithful, but are open minded, you will find many of the statements by Mister Carroll inappropriate to an open discussion of actual science.

meh

the lecturer was well spoken and engaging, but he spent a good deal of time and a lot of words to say not very much. he also talks alot about evolution which has.nothing to do with time or physics.

I think a better title.for this course would be "the history of time, measurement of time and entropy. "

the course can be summed up thus:

there is an arrow of.time going forward in time, because entropy in the past was.less. we're moving towards higher.entropy. no one knows why.

there.are one or.two.lectures that deal with black holes and time travel, but very little about mysteries.

I would recommend other courses instead, but not because of the lecturer. he could probably discuss other physics topics well.

Not so mysterious

What did you like best about Mysteries of Modern Physics: Time? What did you like least?

Sean Carroll is obviously a very bright guy, and one could learn a lot from him. But this book is a disappointment. He attempts to build tension and interest in his topic (entropy, the arrow of time), then shows why that tension is misplaced here (but not over there), and concludes with a cosmos spanning review that brings nothing new.

What was the most interesting aspect of this story? The least interesting?

Entropy is clearly explained.

What do you think the narrator could have done better?

Include a panegyric to the steam engine
