Rated 5 out of 5 by from One Giant Leap for TGC! These are just great examples of a perfect collaboration between two stellar organizations. The videos are informative, enjoyable, fast-paced, still in-depth, and just the right length. My personal favorite is the black holes one, but they're all great. On the music: Eh, it's a little hot (loud) in some places, but I think it's just different and mostly accentuates the content. Just watch the levels a little, guys ;) Can't wait for more!

Rated 5 out of 5 by from Fantastic!!! (Would be better without the music) Wonderful visual presentations and narratives!!! Excellently put together. However, I agree with a previous reviewer that the background music is intrusive and disruptive. It would be better without the music. Thank you very much.

Rated 2 out of 5 by from Excellent material but background music ruins This is the first Great Courses I've ever given less than five stars. The material and concept are just excellent, but the background music is beyond annoying. It is intrusive, repetitive and distracting.

How Dinosaurs Grew So Large and So Small
1: How Dinosaurs Grew So Large and So Small

Until recently, paleontologists had no way to measure the age of dinosaurs or to figure out how they grew. So, we assumed dinosaurs had a physiology similar to modern reptiles. But it turns out that the clues we needed were locked in the animals’ bones all along—in growth lines similar to the annual growth rings in trees. John R. Horner, Kevin Padian, and Armand de Ricqlès, who have studied dinosaur bones together for more than 20 years, break down how they helped to determine the growth rates of many dinosaur species.

Are We the Only Intelligent Life in the Galaxy?
2: Are We the Only Intelligent Life in the Galaxy?

With so many exoplanets out there in the galaxy, it seems reasonable to hope that life may be prevalent. On our planet, it took a series of unusual coincidences to give rise to our intelligent civilization, and it’s quite unlikely such serendipity has taken place elsewhere. Science writer and astrophysicist John R. Gribbin examines how everything had to go just right. Perhaps most unlikely of all, he argues, was the development of our technological species—a feat that is probably unique in the Milky Way.

Decoding the Puzzle of Human Consciousness
3: Decoding the Puzzle of Human Consciousness

Physiological and behavioral evidence indicates that humans are fundamentally similar to many other animals in terms of their responses to painful and pleasurable stimuli. Even so, scientists disagree on whether other creatures have consciousness or can suffer. Dr. Susan Blackmore, a psychologist researching consciousness and memetics, and author of The Meme Machine, explains the arguments on each side of this great debate and introduces her own concept of the “selfplex.”

Why Your Brain Needs Exercise
4: Why Your Brain Needs Exercise

Everyone knows that exercise is good for the body. But it’s also been well-established that exercise has positive effects on the brain, especially as we age. Less clear has been why physical activity affects the brain. Doctors David A. Raichlen and Gene E. Alexander explain how key events in the evolutionary history of humans may have forged the link between exercise and brain function. And they show how cognitively challenging exercise may benefit the brain more so than physical activity, which makes fewer cognitive demands.

The First Monster Black Holes
5: The First Monster Black Holes

In the very distant, ancient universe, astronomers can see quasars—extremely bright objects powered by enormous black holes. Yet it is unclear how black holes this large could have formed so quickly after the big bang. Dr. Priyamvada Natarajan, a theoretical astrophysicist focusing on cosmology, gravitational lensing, and black hole physics, explains how she and her colleagues have tried to solve this mystery by proposing a novel mechanism for black hole formation. Rather than being born in the deaths of massive stars, the seeds of the most ancient, supermassive black holes might have collapsed directly from gas clouds.
