The disordered cosmos: a journey into dark matter, spacetime, and dreams deferred

Prescod-Weinstein, Chanda
"Dr. Chanda Prescod-Weinstein is one of the leading physicists of her generation, at work on the origins of spacetime at the intersection of particle physics and astrophysics. She is also one of the fewer than one hundred Black women to earn a PhD in physics. In The Disordered Cosmos, Prescod-Weinstein shares with readers her love for physics, from the Standard Model of Particle Physics and what lies beyond it, to the physics of melanin in skin, to the latest theories of dark matter - all with a new spin and rhythm informed by pop culture, hip hop, politics, and Star Trek. Prescod-Weinstein's vision of the cosmos is vibrant, inclusive and buoyantly non-traditional. As she makes clear, what we know about the universe won't be complete until we learn to think beyond the limitations of white-dominated science. Science, like most fields, is set up for men to succeed, and is rife with racism, sexism, and shortsightedness as a result. But as Prescod-Weinstein makes brilliantly clear, we all have a right to know the night sky. By welcoming the insights of those who have been left out for too long, we expand our understanding of the universe and our place in it. The Disordered Cosmos is a vision for a world without prejudice that allows everyone to view the wonders of the universe through the same starry eyes"--

Feynman lectures on computation

Feynman, Richard P.
From 1983 to 1986, the legendary physicist and teacher Richard Feynman gave a course at Caltech called “Potentialities and Limitations of Computing Machines.”Although the lectures are over ten years old, most of the material is timeless and presents a “Feynmanesque” overview of many standard and some not-so-standard topics in computer science. These include computability, Turing machines (or as Feynman said, “Mr. Turing's machines”), information theory, Shannon's Theorem, reversible computation, the thermodynamics of computation, the quantum limits to computation, and the physics of VLSI devices. Taken together, these lectures represent a unique exploration of the fundamental limitations of digital computers.Feynman's philosophy of learning and discovery comes through strongly in these lectures. He constantly points out the benefits of playing around with concepts and working out solutions to problems on your own-before looking at the back of the book for the answers. As Feynman says in the lectures: “If you keep proving stuff that others have done, getting confidence, increasing complexities of your solutions-for the fun of it-then one day you'll turn around and discovers that nobody actually did that one! And that's the way to become a computer scientist.”

Multiverse

M a Rothman
"Fast-paced prose, fit-for-Hollywood characterizations, science with a wow factor, and accessible descriptions of complex quantum concepts and experiments... hard science meets pop-science time-travel in this entertaining thriller." - Kirkus Reviews When the future ruins your life... From a USA Today bestselling author: After particle physics professor Michael discovers how to pierce time and space, he meets a student who has memories of her future - and the research they have yet to complete together... "You won't be disappointed" (New York Times bestselling author Kevin J. Anderson). ------ When Michael Salomon woke up Tuesday morning, he did so with a smile, knowing that today would be a positive turning point in his career. With his first child on the way, he couldn't shake the feeling that something bad was about to happen. As he drives into work, he feels a sudden wave of anguish wash over him, and he sees himself alone, at the gravesite of an unborn daughter. It feels like a crystal-clear memory, a waking nightmare that nearly sends him crashing into the car in front of him. The idea of faster-than-light particles has been a part of science fiction lore for fifty years, yet Michael had made a breakthrough discovery late last night. Tachyons do exist. Going back into the office, he hasn't even had a chance to tell anyone about what he's discovered when the men from DARPA came calling. The entirety of his research has suddenly become an object of national security. But it was only when a young college student intercepts him as he gets into his car that he knows the life he's looking forward to is over. The student has memories of her future self... a future where she's worked with Michael on extending his research. She knows things that he's only thought of as possibilities, and she speaks of them as if they'd already happened. And most chilling of all, she speaks of a future where they are both in hiding from the government that sees them as the enemy. MULTIVERSE is a story about a scientist who uncovers a way to pierce the veil of time and space, and has unwittingly opened Pandora's box. Is it even possible to undo what a future version of yourself has done, or is everyone doomed to the chaos that's been loosed on the world?

A serious man

Coen, Ethan
It is 1967 and Larry Gopnik, a physics professor at a quiet Midwestern university, has just been informed by his wife Judith that she is leaving him since she has fallen in love with one of his more pompous colleagues. His domestic woes accumulate: his unemployable brother Larry is sleeping on the couch, his son Danny is playing hooky from Hebrew school, and his daughter is sneaking money from his wallet in order to save up for a nose job. Also, a graduate student seems to be trying to bribe him for a passing grade while at the same time threatening to sue him for defamation, thus putting in jeopardy Larry's chances for tenure at the university. As if all this wasn't enough, he is tormented by the sight of his beautiful next door neighbor sunbathing nude. Larry's search for some kind of equilibrium is conveyed with the kind of humor, imagination, and verbal wit that have made the work of Ethan and Joel Coen so distinctive.

Einstein's Unfinished Revolution The Search for What Lies Beyond the Quantum

Lee Smolin
From Canada's leading mind on contemporary physics, a daring new vision of the universe, and the scandals controversies, and questions that will illuminate our future. Quantum physics is the golden child of modern science. It is the basis of our understanding of our world--atoms, radiation, elementary particles, basic forces and the behavior of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its inventors, strange paradoxes, and implications that seem like the stuff of fantasy. In Einstein's Unfinished Revolution , theoretical physicist Lee Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed our understanding of the universe, before wrestling with the puzzles and conundrums that the quantum world presents. Along the way, he illuminates the existing theories that might solve these problems, guiding us towards a vision of the quantum that embraces common sense realism. Vibrant and accessible, Einstein's Unfinished Revolution brings us a step closer to resolving one of the greatest scientific controversies of our age.

Dreams of a final theory

Weinberg, Steven
The Nobel Prize-winning physicist and bestselling author of The First Three Minutes describes the grand quest for a unifying theory of nature--one that can explain forces as different as the cohesion inside the atom and the gravitational tug between the sun and Earth. Wirting with dazzling elegance and clarity, he retraces the steps that have led modern scientists from relativity and quantum mechanics to the notion of super-strings and the idea that our universe may coexist with others. But Weinberg asks as many questions as he answers, among them: Why does each explanation of the way nature works point to other, deeper explanations? Why are the best theories not only logical but beautiful? And what implications will a final theory have for our philosophy and religious faith? Intellectually daring, rich in anecdote and aphorism, Dreams of a Final Theory launches us into a new cosmos and helps us make sense of what we find there.

Feynman's rainbow: a search for beauty in physics and in life

Mlodinow, Leonard
In the early 1980's, Leonard Mlodinow came to the California Institute of Technology to begin a postdoctoral fellowship. Mlodinow had written a groundbreaking Ph.D. thesis, but he was afraid he was simply not smart enough to be at Caltech. In danger of losing himself watching hours of Rockford Files reruns while waiting for one good idea, Mlodinow took his doubts and insecurities to Caltech's intimidating resident genius and iconoclast, Richard Feynman. So began a pivotal year in a young man's life and a year of awakening. In the funny, inspiring, and revelatory book, Leonard Mlodinow looks back at the time he shared with Feynman: the ideas they explored, the views of life and physics they exchanged, and what Mlodinow learned from a mentor who had not only helped shape the landscape of physics, but whose mind was drawn to all aspects of human experience. In a series of fascinating, sprawling exchanges, Feynman delved into the nature of science, creativity, love, mathematics, happiness, God, art, pleasures and ambition. And as the relationship between the older scientist and Mlodinow deepened - at one point the two crashed a wedding buffet together - their conversations took on a sense of urgency. For while Mlodinow was floundering, Feynman was battling cancer - and confronting his own mortality.

Our mathematical universe: my quest for the ultimate nature of reality

Tegmark, Max
"Max Tegmark leads us on an astonishing journey through past, present, and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and ground-breaking science, he not only helps us grasp his often mind-boggling theories (his website gives a flavor of how they might boggle the mind), but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last--here is a book for the full science-reading spectrum"--

The black hole war: my battle with Stephen Hawking to make the world safe for quantum mechanics

Susskind, Leonard
A mind-bending book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes. What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed it did--and in doing so put at risk everything we know about physics and the fundamental laws of the universe. Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics. This is the story of their united effort to reconcile Hawking's revolutionary theories with their own sense of reality--effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.--From publisher description.

Twenty years of A new kind of science

Wolfram, Stephen
"When Stephen Wolfram's groundbreaking A New Kind of Science was published in 2002, its exploration and analysis of the computational universe of simple programs launched a scientific revolution. Twenty years later, the ideas and results of the book have found countless applications across science, technology and elsewhere-including the recent Wolfram Physics Project and its breakthrough in fundamental physics-and the book has indeed spawned what can only be described as a new kind of science. Here Wolfram reflects on the first two decades of A New Kind of Science, discussing some of the major implications that have emerged so far, as well as his far-reaching new thinking building on the conceptual framework developed in A New Kind of Science. Written in Wolfram's popular and accessible style, the book provides a window into one of the most vibrant intellectual developments of our time. Recognizing A New Kind of Science's significance not only in science but also in the arts, the book includes a gallery of pieces created over the past 20 years by artists inspired by the book"--

Galileo and the Science Deniers

Mario Livio
Although Galileo Galilei lived and died centuries ago, his story is more relevant to our lives than we might realize. Today we face enormous challenges such as climate change that are disregarded or questioned by those who fear that their implications will damage business profitability. Others posit a false dichotomy between religion and science in order to reject scientific evidence whose implications they fear. Galileo confronted this problem 400 years ago. His discoveries were based on observation and experiment. His telescopes revealed previously unknown planets, moons orbiting other planets, and other discoveries that essentially confirmed the Copernican universe that the Church had rejected as heretical because Church theologians insisted on a literal reading of the Bible. Even St. Augustine in the fifth century maintained that the Bible pertained to the realm of faith, not reason. But when Galileo argued essentially the same position before an ecclesiastical court in Rome, he was forbidden from publishing any more books. Livio's life of Galileo shows us how the great thinker made his discoveries about the heavens and also formulated fundamental laws of physics. As an astrophysicist, Livio brings insight into how Galileo reasoned his way to his conclusions, which we know today were accurate. Along with Newton, Galileo remains one of the two great figures at the dawn of the scientific revolution. He insisted on reaching the widest audience possible, publishing his work in Italian rather than Latin as had been the case until his time, when vernacular languages were rapidly replacing Latin throughout Europe. Galileo believed that every educated person should know science as well as literature. Did Galileo actually say at the end of his trial when he was forced to recant his discoveries, as legend has it, And still it moves, referring to the motion of the earth around the sun? Not likely, says Livio, but Galileo nonetheless remains an inspiration to scientists and those who value open-minded inquiry, which as Livio reminds us, remains threatened even today.

A project to find the fundamental theory of physics

Wolfram, Stephen
'In many ways it s the ultimate question in natural science: How does our universe work? Is there a fundamental theory? An incredible amount has been figured out about physics over the past few hundred years. But even with everything that s been done and it's very impressive - we still, after all this time, don t have a truly fundamental theory of physics.' The Wolfram Physics Project is a bold effort to find the fundamental theory of physics. It combines new ideas with the latest research in physics, mathematics and computation in the push to achieve this ultimate goal of science. Written with Stephen Wolfram's characteristic expository flair, this book provides a unique opportunity to learn about a historic initiative in science right as it is happening. A Project to Find the Fundamental Theory of Physics includes: The announcement of the project; A technical introduction; A history section that outlines the backstory which led Wolfram to this point; Background information from computational essays published by the author in 2015 and 2017; Foundational information, including historical notes and an excerpt from Wolfram's; 2002 New York Times Best Seller A New Kind of Science; Hundreds of beautiful full-colour visualisations. Stephen Wolfram is a distinguished scientist and best-selling author, and the creator of some of the world's most respected software systems, including Mathematica, Wolfram|Alpha and Wolfram Language. For more than 30 years he has been the CEO of the global technology company Wolfram Research.
