This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid and lyrical style, he discusses many topics from astrophysics and solar system science, to colonization, terraforming and the search for extraterrestrials.
In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid and lyrical style, he discusses many topics from astrophysics and solar system science, to colonization, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were thirty years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions. Who knows what wonders this third millennium will reveal, but one thing is certain: Carl Sagan played a unique role in preparing us for them.Binding Type: Hardcover

Versatile sneakers. The upper makes the difference.
Size: 11, Color: Black/Smoke Grey/Medium Ash
Very good quality shoes for this price.
My impressions:
1. The Flyknit upper feels very soft and comfortable. I don't get the rough, scratchy feel of some lower-quality options. It also disperses heat very well.
2. The midsole is firm, but not overly hard. I find it well-balanced, as it has good shock absorption while still being soft enough to cushion the soles of my feet.
3. They're versatile. For me, especially the black ones with the dark gray sole, they work for casual wear, going to the gym, walking, and short, light runs.
4. I consider them very decent shoes for walking and short runs under 5k.

Offer lots of support and traction- perfect gym shoes
So comfortable- they offer a lot of support and I can tell they will last for a long time (and I’m hard on my gym shoes!). I’m actually a female but I sized down and they fit perfectly. I found them on sale and definitely recommend them as they are well worth the price.

Comfortable nike running shoes.
Size: 13, Color: Black/Summit White/Anthracite/Cyber, Size: 13, Color: Black/Summit White/Anthracite/Cyber
Nice and comfortable from the moment that I put them on my feet. Feels like you’re walking on memory foam. You have to buy comfortable shoes when you’re on your feet all day. I do Amazon Flex in. These will be perfect although I have several pairs so that way, the shoe lasts longer. Definitely would buy these in different colors very satisfied.

Good shoe, seems physically big
I really like these shoes. I’ve been able to wear them for about a week now and am really impressed with how they’re holding up. A lot of my shoes start to squeak in a similar amount of time and these still feel like they just came out of the box.
I especially like the heal support, it feels like it’s really gripping the heal nicely
My one complaint is that they seem physically larger than most size 11 shoes from Nike I buy. In spite of fitting the same inside, the actual shoe seems about an inch longer than my other Nike size 11s. It’s not a deal breaker and it doesn’t impact the comfort, it might even make them more comfortable, but they look a bit large on my foot. And if you have a narrow foot, you might be swimming in these.

Can’t Miss Shoe
Size: 11, Color: White/Blue Crystal/Total Orange, Size: 11, Color: White/Blue Crystal/Total Orange
Great looking shoe! Fit to form, I wear a size 101/2 or 11 and I ordered a size 11 and they fit perfectly. Soft and comfortable perfect for walking as I suffer from knee and back pain at 59 years old…. Don’t judge me. Normal width size for me so not sure about the wide fit but the toe room for me is comfortable. Great choice will definitely recommend.
