The Inexplicable Universe with Neil deGrasse Tyson

Recently, I completed viewing Neil deGrasse Tyson’s Teaching Company lecture series The Inexplicable Universe which is currently available on Netflix streaming. Dr. Tyson is one of the great communicators of scientific ideas to the general public since Carl Sagan. He evangelizes proper science frequently on television shows such as The Colbert Report. His most recent exposure to the public was in the form of the revamped, contemporary version of Cosmos: A Spacetime Odyssey, the original version of which was hosted by the aforementioned great astrophysicist Carl Sagan. Dr. Tyson has distinguished himself through his great willingness to make scientific ideas (and more importantly attitudes toward science) more palatable and relatable than they might otherwise be.

The Inexplicable Universe is divided into six 30-minute lectures: 1) History’s Mysteries, 2) The Spooky Universe, 3) Inexplicable Life, 4) Inexplicable Physics, 5) Inexplicable Space, and 6) Inexplicable Cosmology. As I said earlier, I watched this series on Netflix which means I could only view the lectures. Should you choose to purchase the course from The Teaching Company, it will, like all of their courses, likely include a course outline with more in-depth notes and bibliographical references for further reading. Of course, you choose your level of involvement, so it is not essential to complete the readings or view Dr. Tyson’s notes and comments to understand and benefit from the lectures.

I’ve seen Dr. Tyson lecture and sit for interviews numerous times and I must say that in this Great Courses series he is at his finest. With the first lecture, “History’s Mysteries,” Dr. Tyson reviews myriad problems from the history of science. These puzzles were only solved through the application of modern science and its focus on experimenting rather than pure reason. Dr. Tyson walks us through the solution to many of the mysteries of the past which were solved using science and have become almost mundane at this point. A great example is 18^th century scientists’ insistence on the existence of ether, an invisible substance through which sound waves travelled. This was later proven to be wrong. That is, scientific rigor in experimentation (specifically, the Michelson-Morley experiment) demonstrated that light travelled at the same speed all of the time; therefore, the ether that was supposed to transmit light in wave form didn’t do it.

Lecture 2 is titled “The Spooky Universe” and generally covers quantum mechanics and fundamental particles, explaining how fantastical many of our accepted concepts are. The third lecture, “Inexplicable Life,” talks about the uniqueness of human life in the universe and the conditions that allow life to flourish, as well as the possibility of life outside of our Earth-bound existence. Lecture 4, “Inexplicable Physics” might be the most interesting of the six-part series. Dr. Tyson reviews the development of the field of physics and the search for a unifying theory such as “String Theory.” The fifth lecture is “Inexplicable Space” and it reviews humankind’s search for understanding of the cosmos. The most fascinating bits in this lecture cover dark energy and dark matter as well as the theoretical experience of being at or near a black hole. The final and sixth lecture “Inexplicable Cosmology” goes into depth about the current edges of study in cosmology. The multiverse, antimatter, tachyons and other theoretical advances of the past few decades are covered in Tyson’s inimitable style.

So that is a brief review of some of the content of The Inexplicable Universe. I had been exposed to most of its ideas from other books, lectures, and even podcasts; however, I have to give a strong recommendation for this lecture series because of its accessibility. It is one of the few series that talk about such complex ideas that requires no previous exposure to mathematical or scientific ideas. All you need is an attentive and open mind and you will gleam something or many things from the lectures. As always, happy learning!
