Astrophysics for People in a Hurry: Essays on the Universe and Our Place Within It

Product Information

Which is why “Astrophysics for People in a Hurry” is not only a book about people who don’t have enough time to learn more about the universe but want to. A century later, people developed technology powerful enough to see these waves, and humanity “would finally catch up with the prediction, just days before that gravity wave, which had been traveling for 1.3 billion years, washed over Earth and was detected.” Prhaps the battle for the scientific hearts and minds is as pitched as ever, with the sales of his book a sign not that the scientific worldview Tyson espouses in winning, but rather of the intensity of the fight.

Tiešām viss par kosmosu no Lielā sprādziena līdz kosmiskajam perspektīvam. Paskaidrots pēc iespējas vieglākā valodā. Astrophysics teaches us that we’re not the centre of the world… it teaches us to have a cosmic perspective” Even after it was conclusively proven that the Earth is not the center of the Universe, philosophers still believed in some divine presence, because some of the planets’ motions were inexplicable. Fourteen billion years ago the universe was teeny tiny, 'a trillionth the size of the period that ends this sentence.' It exploded in 'The Big Bang' and expanded at a phenomenal rate - one second after the big bang the universe was already several light years across (at least 18 trillion miles).Tyson is quite adamant in insisting that most of the things he talks about are undeniably true . “The power and beauty of physical laws,” he writes, “is that they apply everywhere, whether or not you choose to believe in them. In other words, after the laws of physics, everything else is opinion.” The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains spill out, making us susceptible to believing anything we're told. What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There’s no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day. Astrophysics for People in a Hurry by Neil deGrasse Tyson – eBook Details However, this is not Astrophysics for Dummies. There are assumptions made for the audience - you do need a bit of a working knowledge on particles and space to fully understand the significance of the text.

Tyson, though, keeps a little bit of attitude in the book. In a chapter about interplanetary space, he refers to a volume “large enough to contain the orbit of Neptune, the outermost planet” followed by a footnote: “No, it’s not Pluto. Get over it.” That is, thankfully, the only reference to the debate over Pluto’s planetary status that helped make Tyson famous—and infamous—years ago. Reading this book reminded me of things I'd forgotten and taught me a lot of new things. It had me wrestling with chemistry and physics which generally go over my head -- but it had me wrestling. He never lost me and I never gave up trying to understand parts that were hard for me to comprehend. As he showed in the two seasons of Seth MacFarlane's "Cosmos," Neil is the one you want as your guide to the basics of astronomy which among all the sciences has the most to discover. How exciting! Reading this been an educational, enchanting and uplifting experience. The book’ impressive sales would seem to support Tyson’s view that there is a “genuine increase” in interest about science. (Assuming, of course, people are actually reading the books they buy.) But there is a tremendous amount of pseudoscience out there as well, largely neglected in the book—remember all the claims that the world was supposed to end last weekend? So perhaps the battle for the scientific hearts and minds is as pitched as ever, with the sales of Astrophysics for People in a Hurry a sign not that the scientific worldview Tyson espouses in winning, but rather of the intensity of the fight. Everything started to cool off and make room for the matter to grow bigger and stronger than antimatter. Antimatter destroyed plenty of matter that existed in the universe at its inception (roughly between its first second to the first two minutes of its existence). During this time, helium and hydrogen grew abundant. About 13.8 billion years ago, when the universe started expanding from a very high-temperature and high-density state, creating space, time, physical laws and everything else.

Even more interesting, it took billions of years for the earliest plants to appear on the planet and almost a billion more for the earliest apes. Astrophysics for People in a Hurry] is not quite astrophysics for dummies; while it is simplified, it is not simple. It is more a collection of the best and most thrilling moments; astrophysics’ greatest hits." At first, a few Skittles get into your mouth and you can taste them. Awesome, you think. I love Skittles. He concludes, “The day our knowledge of the cosmos ceases to expand, we risk regressing to the childish view that the universe figuratively and literally revolves around us. In that bleak world, arms-bearing, resource-hungry people and nations would be prone to act on their ‘low contracted prejudices.’ And that would be the last gasp of a visionary new culture that could once again embrace, rather than fear, the cosmic perspective.” (Pg. 208) Neil DeGrasse Tyson, an American astrophysicist, is the Director of the Hayden Planetarium, and the host of 'Star Talk' and 'Cosmos: A Spacetime Odyssey.' Tyson is also a very funny guy, and his sense of humor lightens the 'lessons' in Astrophysics for People in a Hurry - which contains a brief overview of cosmology.

So galaxies that are now visible to our telescopes will eventually disappear from view. Tyson notes, "In a trillion years, anyone alive in the Milky Way may know nothing of other galaxies, and will see nothing but a dark, endless void." :(Although difficult to choose from, here are the lessons that are the most fun and useful for you to know: I borrowed this book through kindle unlimited. It is an excellent astrophysics book for the layperson. Since as much as we know – or, as in this case, have probably predicted well enough about the universe – there’s much more that we don’t know. The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains spill out, making us susceptible to believing anything we’re told. The” The book's conversational tone makes it easy to follow and provides insight into the way astrophysics works in our everyday lives."
