Dark matter and the dinosaurs : the astounding interconnectedness of the Universe. I now visualize the entire Solar System including its far flung halo of Oort objects moving through the galaxy. I actually laughed audibly while reading that section. We could call it a shot in the dark. From the far-flung reaches of space, the makeup of the universe and our solar system's place within it, to the mysterious and elusive stuff of dark matter and how it affects life here on Earth. Fascinating, intriguing, thought-provoking yet also confusing and complicated. The Edge of Our Existence Reach out and touch something.
The Speed of Dark, as any Terry Pratchett fan could tell you. Mas a explicação toda para chegar nesse ponto é boa, bem descrita e compreensível. Author by : John C. Here's my take-away from that. Space is far more empty than we realize. She is well qualified to talk about this being Professor of theoretical particle physics and cosmology at Harvard, but this is one book that might be beyond the general science reader, even though they should probably give it a go. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us.
While the science is fantastic, interesting and well informed as an evolutionary biologist I noticed a couple of glitches, nothing wrong, just misleading , but the very best part of the book is explaining how science is done. Dark matter interacts with ordinary matter and itself solely through gravity as far as we know. However, she is excited about the kinds of questions this new direction is taking her. The dinosaur chunks are not her area of expertise. Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes Bestselling author of Warped Passages and Knocking on Heaven's Door and one of today's most influential and highly cited theoretical physicists, Professor Lisa Randall once again effortlessly delivers fascinating science to the general reader.
Each drawing is accompanied by a brief description that educates as it entertains. Here's what I mean by that: though I am not a physicist, I have read plenty of books like this one, so my level of knowledge is definitely beyond rudimentary. In this book, Randall puts forward the argument that as our solar system passes through the central plane of the Milky Way galaxy every 30-35 million years, it passes through disc of dark matter, which leads to gravitational disruption of the Oort comet cloud at the edge of our solar system, leading some comets in the cloud hurtling towards the Sun and occasionally impacting with the Earth. To make her case she ties together diverse scientific disciplines including cosmology, particle physics, astronomy, geology and paleontology. She began her physics career at Stuyvesant High School in New York City. And what should the book have been called? Dark Matter By Blake Crouch — New — 1101904224.
In fact, she seems to have pared down the flourishes to a minimum. The most interesting part for me is in the middle of t Terrific tour of the latest ideas in physics about the evolution and structure of the universe and how it relates to the history of our solar system and life on earth. Turns out it wasn't my alley, it was a dead end. It's a great case study in how science works. It's impossible to read this book and look at either Earth or sky again in the same way.
Science Salon Archives Science Salon is a series of conversations between Dr. The period of this oscillation is about 32 million years. An oscillating bobbing solar system crossing the Milky Way- A comet existing far away might feel this disruption and at the same time the overheated Earth's core is sizzling due to the Dark matter clumps that entered and are waiting to erupt- Can this truly happen? I suspect the book is a wonderfully enlightening read, but due to the low wattage of my brain cells, I can only say I enjoyed the challenge of reading it. Even the discussion of dark matter is over-familiar, except for the minor and unconvincing twist in the tail. Randall is careful to craft her model so that it conforms to known measurements, but this hardly makes it true.
Randall examines the proposals that these impact events occur more frequently at regular intervals and settles on a period of 32 million years. I cannot wait to see what the telescope Gaia finds. A member of the National Academy of Sciences, the American Philosophical Society, and the American Academy of Arts and Sciences, she is the recipient of many awards and honorary degrees. In that one 90% of species were wiped out, including insects. When we think about our planet today, we might also want to better understand the context in which it developed. Mountains arose from tectonic plates that collided, and the molten magma that drives these movements is the result of radioactive material buried near the core of the Earth.
The current rate of species extinction is comparable to the one that took place 250 million years ago, the Permian-Triassic extinction. All in all, a noble effort. Randall has a mixed style of writing. My only complaint about the book, is that its organization seems to be a bit strange at times. Coloring the drawings helps reinforce the color, image, and shape of each dinosaur, improving your memory and perception while offering a pleasant and easy way to learn. National Academy of Sciences member Lisa Randall's book was published in 2015.
I heartily recommend this book to everyone who is interested in learning about how modern science is really done these days. I am not giving anything away by laying it out. Once everyone is in, the whole crew moves through space or circle in this instance as one. The main subjects of this book are dark matter and dark energy, and their potential effects on life on Earth as we know it today. She's best when she gets to particle physics and dark matter. The Cretaceous-Paleogene event of 66 million years ago that killed off the dinosaurs was caused by a comet. Ordinary matter—important as it is to us— does not tell the whole story.
