Description
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

Great price!
Color: Silver
For the price I'm extremely happy with this juicer! Easy to clean! I will say it's a little difficult to make large batches with this juicer. I just keep a pitcher beside me and dump the container when it gets full. I do find myself cleaning the grater a few times while I'm juicing because it does tend to get clogged. If you're new at juicing and want to try it...get this! Totally worth it! Gets the job done. I've used mine several times so far, but still can't see myself paying $300+ for a juicer.

Not that great
Color: Silver
Not bad for the price but it leaves a lot of pulp behind and I don’t like that it could be better but again decent for the price easy to use you just have to strain the juice a lot to get all the pulp out and once you do it’s like 60% pulp 40% juice when you go in the back to look at or throw out the juiced fruit you can feel how much juice is still in it

🍎🍐🍊🍋🍋🟩🍌🍉🍇🍓🫐🥭
Color: Silver, Color: Silver
Easy to use, fairly easy to clean if you don’t mind all the parts. I feel that the noise level was normal for a juicer. The juice pitcher doesn’t hold much, but if you are just juicing for 2 people it’s fine. I did have an issue with mine and had to order a replacement, but overall it was still a great buy. I’m new to juicing so I didn’t take the core out of a plum and ended up cracking my fruit/veggie pusher, but other than that I love it. I also like the fact that it comes with a juice recipe booklet to try different juices.
