Is Einstein Still Right?: Black Holes, Gravitational Waves, and the Quest to Verify Einstein's Greatest CreationAlbert Einstein is often viewed as the icon of genius, and his theories are admired for their beauty and correctness. Yet the final judge of any theory is the rigorous test of experiment, not the fame of its inventor or the allure of its mathematics. For decades, general relativity has passed test after test with flying colors, including some remarkable new tests using the recently detected gravitational waves. Still, there are reasons for doubt.
Albert Einstein is often viewed as the icon of genius, and his theories are admired for their beauty and correctness. Yet the final judge of any theory is the rigorous test of experiment, not the fame of its inventor or the allure of its mathematics. For decades, general relativity has passed test after test with flying colors, including some remarkable new tests using the recently detected gravitational waves. Still, there are reasons for doubt. Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. Until recently, this was considered to be a purely academic affair. But as more and more data pour in from the most distant corners of the universe, hinting at bizarre stuff called "dark energy" and "dark matter," some scientists have begun to explore the possibility that Einstein's theory may not provide a complete picture of the cosmos. This book chronicles the latest adventures of scientists as they put Einstein's theory to the test in ever more precise and astonishing ways, and in ever more extreme situations, when gravity is unfathomably intense and rapidly churning. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this book takes the reader on a journey of learning and discovery that has been 100 years in the making.Binding Type: Hardcover

Like it
Color: Hot Pink/Smoke
The Speedo Kids’ Sunny G swimming goggles were very much liked by the child. They sit comfortably, do not leak and do not put pressure on the eyes. The soft strap does not pull the hair and is easily adjustable, so the child can put them on himself. They hold well during swimming and do not slip. The lenses do not fog up and provide good visibility underwater.

Good fit for my *almost* 9 yo
Color: Margarita Pink/Vermillion
Cute deign. Proper water protection. Great hold to the string and the clasp. Lenses are very clear and colors are bright and cute. I was kind of worried about the sizing for my almost 9yo, but these sit very well and I think will work for her for quite some time too.. not only size-wise but quality-wise too. These seem well made and durable.

Perfect Fit & Great Quality for Kids!
Color: Sky Blue/Celeste
These goggles are amazing for little swimmers! They fit my child perfectly without leaking or slipping, and the adjustable straps make them super easy to customize. The soft seal is comfortable around the eyes, and my kid actually enjoys wearing them , no complaints about water getting in. The lenses are clear and don’t fog up, even after long pool sessions. Great quality from Speedo as always!

so cool!
Color: Mariner Silver/Emerald/Silver, Color: Mariner Silver/Emerald/Silver
so cool!! they were a bit big on my 4 year old, but fit perfectly on my 8 year old! since it was a little wide, the water poured in, but my 8 year old really enjoyed it and they look like sunglasses!! he said they were comfortable and they were so easy to put on and take off, since the straps weren't rubber. the lens scratch a little bit and they don't come with a pouch to keep in. still, great value for the money.
