Don't Waste Your Time

Revisado: 03-21-19

First of all, this guy talks a hundred miles an hour, and what he says is the most superficial explanation of Einstein's General Theory of Relativity. You know what bothers me about guys like this one? It's like a 5th grade math teacher who goes over addition and subtraction with his students and then starts throwing in calculus terms along with random differential equations expecting you to "keep up, people". And of course he never does explain the "why" , only a tiny bit about the how. Shame...

Good Stuff About Dark Matter

Revisado: 12-03-15

I knew about dark matter and its gravitational influence on ordinary matter, but I thought dark matter could only exist in any measureable quantity outside our galaxy. But now I know that pockets of dense dark matter could exist inside our galaxy which can perturbe the Oort Cloud sending comets into our inner solar system. It's a little more complicated than this, other factors contribute as well, but if you listen to this audio book, you'll discover that dark matter is more than just scaffolding.

Tremendous Book

Revisado: 10-20-15

Truly a worthwhile read. Bryson captures the splendid detail of almost everything worth mentioning that was ever discovered in the world.

overall not bad

Revisado: 09-21-15

the beginning chapters are the best. they point out how reality changed with the discovery that certain bacteria cause disease and so antibiotics were invented. he describes how newton overturned aristotle and how einstein overturned newton. he describes the standard model, chaos theory and inflation theory of the early universe. but after that he just gives an account of how the world is today especially brought about by computers and the internet which wasn't all that informative.

Pretty Good

Revisado: 07-22-15

The speakers are all very good. They do mostly explain various pholosophers point of view. The one on Martin Luther was the best for me because it explained the mind and thoughts of Luther that brought about the Reformation.

Einstein Theories

Revisado: 05-27-15

Overall more of a review of quantum physics than Einstein's theories. Also, lectures are before discovery of Higgs boson. Explains standard model superficially. Superficial explanation of time dilation.

Mostly Old Stuff

Revisado: 05-15-15

From what I could pick up, this is from 2007. For example, the instructor talks about the search for the Higgs boson and what he believes will be found. This is a light brushing of particle physics. If you've already done some study of this, it will be a repeat of what you already know. You'll also recognize some mistakes because his knowledge is somewhat old. If you've never read anything on particle physics and are curious, this is an ok introduction even though some of what you'll hear is either wrong or not up to date.
