Rated 5 out of 5 by from Imagine the Possibilities! Dr. deGrasse-Tyson has an amazing capacity to take extremely complex subjects and distill them to their essence. He then outlines his thoughts in a straightforward, clear manner that reveals his thinking on the subject - and it's clear he has given these subjects a great deal of thought!

Rated 5 out of 5 by from Segments were broken down efficiently This was great course, very happy I got this. The course is broken down into manageable segments that don't overwhelm the viewer making for easy break points.

Rated 5 out of 5 by from The Inexplicable Universe: Unsolved Mysteries I just purchase the course in a 4 course package. Neil degrade Tyson does his usual excellent presentation on all subjects of the course. It will be one of my treasured dvd's to watch many times to be able to grasp all it's content!

Rated 3 out of 5 by from The Inexplicable Universe I've purchased numerous courses and additionally viewed or listened to others that the local library has. Two thing made me uncomfortable with Mr. Degrasse. 1) he comes off as someone that is so full of himself, 2) in the first 3 of 6 lectures, he almost comes to a giggle when he refers to earlier peoples belief in that certain conditions are derived from God. I never got this from any other course I've purchased to listened to; he mad me feel very uncomfortable. This is the first time I'm submitting a review

Rated 4 out of 5 by from Tyson's Skilled The professor has an amazing talent for conveying very complex issues in understandable ways. He is one of the best scientific communicators of our age. My criticism of this course is that he comes across as overly dismissive of religious people. Isaac Newton was a strong Christian, and the professor implies that this was a weakness or only a result of Newton's limited understanding. I wish Dr. Tyson had acknowledged that someone can be both religious and scientific or simply left this topic alone. Thankfully, this is a relatively small part of the course, and I was able to ignore it and still enjoy the rest of the content, which is skillfully presented in an educational and entertaining manner.

Rated 5 out of 5 by from Great, great Course. This was the first course I bought. I was overwhelmed by it. It was all I hoped it to be. A very exceptional orator, well thought out, easy to follow and extremely educational for the lay person.

Rated 5 out of 5 by from very engaging and educational Dr. Tyson is great. He has a way of communicating complex issues with clarity and humor. He makes science fun. I have read many books on cosmology and particle physics and Dr. Tyson’s explanation of elementary particles is the clearest and most concise I have encountered. Although the course purports to covers a few specific mysteries the background of the mysteries provides a good chunk of knowledge. I have viewed the DVD several times just for the entertainment value. This course is one of the best uses of a viewer’s time possible.

Rated 3 out of 5 by from I Found Nothing New I hate to write anything unfavorable related to what seems to be America's most popular face for modern science. I'm not a scientist, although I've always had an interest in science and have listened to quite a few Great Courses over the years, especially in the areas of science. Perhaps that was my downfall: I had heard too much. I honestly cannot remember a single new idea that was presented in this short, one-DVD six-lecture program. For me it turned out a disappointment and a waste of time. For someone just now developing some interest in modern science and its questions, perhaps it might be an interesting introductory course. I'm not really able to speak to that well myself, because it wasn't where I was at when I got this.

Rated 4 out of 5 by from Great Gift for an Astrophysicist This was a gift for our grandfather an astrophysicist. The course was a refresher, but not totally or completely current.

Rated 5 out of 5 by from Love it Love Dr Tyson, he makes astrophysics fascinating!!!
Date published: 2017-12-13
Rated 5 out of 5 by from Challenges your curiosity Unbelievably interesting! Fun to follow and to watch. Neil deGrasse Tyson is a great scientist but also an entertaining presenter. He makes you think! For instance: Scientific DNA analasys indicates that the DNA of humans varies only by 1% from the DNA of chimpanzees. Imagine, when foreign life from the universe visits us on earth and finds our DNA just 1% different from theirs ---- will they lock us up?

Rated 5 out of 5 by from Excellent course. Highly recommended. A Much See. This is an excellent course and is highly recommended. I will watch this course more than once.

Rated 5 out of 5 by from A wonderful whirlwind tour! A thoroughly enjoyable tour of a select number of topics still mystifying astrophysicists. The professor is engaging & has a knack for distilling complex facts into understandable concepts. The course is made even better by the careful addition of explanatory graphics; I also enjoyed the accompanying sounds/music etc., which again were balanced just right.

Rated 3 out of 5 by from A little too shallow How do you explain the mysteries of physic in 6 lectures? Superficially. As impressive as Professor Tyson's credentials are and as gifted as he is at communicating complexity to us normal folk, this course is just too short. I cannot recommend it to anyone that seeks the moments of enlightenment that I expect from The Great Courses. Perhaps try "The Theory of Everything" by Professor Lincoln. At 24 lectures it is more of a commitment but I sincerely believe it is more rewarding.

Rated 5 out of 5 by from So likable! The best thing (it's hard to choose just one) about Neal deGrasse Tyson's productions is that while he doesn't make a show of being humble, he truly is. He lets his brains and personality show and yet isn't making the whole program to be about him. The material was well chosen to fit his theme, he made it understandable yet fascinating, and I felt he was sharing it rather than "teaching" me something I did not know, or that only someone as brilliant as he could convey the interest of it all. He is probably the one man I would most like to have a nice long dinner with. Thanks for an enjoyable and educational course. Janet Knori

Rated 1 out of 5 by from The Inexplicable Universe I have purchased more than 60 courses from the Teaching Company. But this course seems to be a complete failure. Instead of discussing a few topics in depth,this mentions each topics in a few minutes. They are incomprehensible to young people as well as any mature people. I hope I may get refund.
Date published: 2017-04-16
Rated 5 out of 5 by from The Inexplicable Universe EXCELLENT. Tyson is a superb speaker/lecturer, the best. He does a superior job of setting out the still unsolved mysteries of the universe, including the still unexplained slight deceleration of Pioneers 10 and 11 as they leave the solar system . My only complaint would be that the course is too short.

Rated 3 out of 5 by from Did You Ever Wonder? This was a very interesting "course" but much too short. I wish it had included even a brief discussion on paper. The possibilities suggested were intriguing; is anyone actually working on some of these ideas? I understand the difficulties of such research, but hope it continues. Let us hope that this inspires more people to consider the mystery of the universe!
Date published: 2016-12-12
Rated 5 out of 5 by from very nice little survey course There is irony here. For such an immense subject, this is a very short course. There naturally is a tremendous amount that we do not know about the incomprehensible vastness of the universe and the incomprehensible complexity of life. This course nicely summarizes the current state of our not knowing. Of course, because the entire course is only 3 hours long, no subject is covered in depth. The course inspires further exploration. In that regard, it serves its purpose well.

Rated 4 out of 5 by from Entertaining Overview This course lightly touches on a variety of scientific topics . From the course description I expected it to be thought provoking entertainment and that is exactly what Professor deGrasse Tyson delivers. The Professor presents the material with clarity and enthusiasm and therefor this course can be enjoyed by scientists and non scientists alike. As someone with a college scientific background, I would have liked a little more detail about the research and studies currently being done at the forefront of the various fields, but all in all this course was great fun to watch.

Rated 5 out of 5 by from Very Entertaining I found the presentation to be very sincere, with an entertaining delivery. Professor Tyson seemed passionate about the course material, and was interesting and humorous. He also took a philosophical approach at certain times, which lended to the material well. While it doesn't feature any information that dedicated students would not know, this is a great short course for the casual person interested in space or science in general. This course also seemed to have a higher production quality than others, not that it should be a major selling point.

Rated 4 out of 5 by from Short & Excellent Presentation of Tough Material! There are six (6) classes, so it's not like you're getting deep it relates to this course. And make no mistake about it, there is some challenging stuff in each of the six classes. But Neil d.T just presents so darn well! In fact, some of his enthusiasm and curiosity on a given topic is infectious, so don't be surprised if you decide you want to look deeper into one (or more) of the subjects. No, this course will not make you a "resident expert" on the material but it easily leads you in the direction to want to become one!

Neil deGrasse Tyson

Of all the amazing things about the Universe, I think two stand above all the rest. One of them is that we know so much about the universe, but another is that there's even more that we don't know.
