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 charger. My new favorite.
Color: Blue
I am very happy with this Anker smart charger. It displays the current wattage, recognizes plugged-in devices, and charges my devices much faster. Its compact size is also great for travel, and the product seems well-built and durable.

Not bad
Color: Orange
It’s a cool charger. It seems to work as advertised, as in it trickle charges when needed or pushes the power hard when you need it. The only complaint I have is the animation lasts a little long and there seems to be no way to manually turn it off when you want to. When plugging in my phone at night, it’s annoying to have that much light for so long when trying to sleep. That all said, I’d buy it again if this one failed, I do like it, just that one annoying thing.

Best laptop sleeve on the market — and I've tried plenty!
Size: 13.3 inch, Color: Black, Size: 13.3 inch, Color: Black
As someone who reviews products regularly, I have pretty high standards and I don't hand out 5 stars easily. But this MOSISO sleeve? Completely earned it. I've tested a lot of laptop cases over the years and this one genuinely stands out from the crowd.
The quality is immediately noticeable right out of the box — the material feels premium, looks sleek, and has held up flawlessly through heavy daily use. No pilling, no wear, no disappointment.
The fit on my 13-inch MacBook is perfect. Snug without being tight, and sliding the laptop in and out is effortless every time. The zipper is smooth, the padding is substantial, and it slips into my bag without adding unnecessary bulk. I've gotten multiple compliments carrying it around at coffee shops and the office.
I also accidentally knocked my bag off a chair recently and my MacBook came out completely fine — so the protection is definitely real and not just marketing fluff.
For the price point, the value here is genuinely hard to beat. I've reviewed sleeves twice the cost that don't come close to this level of quality and finish. MOSISO really delivered with this one. If you're on the fence, trust me as someone who does this regularly — it's absolutely worth it.
