Engineering Physics

Number theory is the branch of mathematics that is primarily concerned with the counting numbers. Of particular importance are the prime numbers, the "building blocks" of our number system. The subject is an old one, dating back over two millennia to the ancient Greeks, and for many years has been studied for its intrinsic beauty and elegance, not least because several of its challenges are so easy to state that everyone can understand them, and yet no one has ever been able to resolve them. But number theory has also recently become of great practical importance.

La théorie quantique validée par l'expérience...La naissance mouvementée de la théorie quantique a marqué la première moitié du XXème siècle. Validée par l'expérience, elle est aujourd'hui une théorie universelle qui régit les phénomènes physiques aux différentes échelles... Révolutionne notre vision du monde.Ses aspects radicalement nouveaux défient le sens commun et nous obligent à reconsidérer les rapports de la matière avec l'espace et le temps.

Dimension W: Book II expands a unified framework that rethinks physics, consciousness, intelligence, and life through the geometry of constraint space. Building on Dimension W: Foundations, this volume develops Dimension W as an ontological layer that interfaces with spacetime by structuring energy, information, and meaning at every scale.

Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public goods. His point of view is rationalist, realist, reductionist, and devoutly secularist.

This book is about science and how it works. It is about what it means for a paradigm to shift and what it really takes to shift it. And it is about the strange and unusual world of quantum physics and what it tells us about who we are. At the start of the 20th Century, a dramatic revolution in science occurred. Over the course of a few decades our most fundamental notions of time, space and consciousness were all being called into question. In undeniable ways, it became clear that the nature of reality is intimately interwoven with our experience of it.

Perhaps the greatest physicist of the second half of the 20th century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits.

How does soap know what's dirt? How do magnets work? Why do ice cubes crackle in your glass? And how can you keep them quiet? These are questions that torment us all. Now Robert L. Wolke, professor emeritus of chemistry at the University of Pittsburgh, provides definitive - and amazingly simple - explanations for the mysteries of everyday life.

Most of us don't actually understand quantum physics, and if we understood it we'd probably be rich and beautiful and happy, right? After all, there are plenty of people out there trying to sell you quantum crystals to align your quantum energy with your quantum destiny. Luckily, as pseudo-science takes over the internet and it's getting harder and harder to separate alternative facts from real science, Chris Ferrie (an actual quantum physicist!) is here to explain quantum physics in a way that makes sense, so you can see the hucksters and bullsh*tters coming from a mile away.

What if reality is not a branching forest of infinite timelines, but a single, irreplaceable world whose value becomes clearer the moment we strip away seductive myths? This book confronts one of the most persistent modern fantasies—the idea of parallel universes—by examining it through science, philosophy, and the psychology of human perception. It exposes how easily speculative models slip into pseudoscience, how cultural repetition creates the illusion of credibility, and how misused scientific language blurs the boundary between rigorous inquiry and imaginative fiction.

The universe is vast—unfathomably so. It stretches beyond our imagination, a seemingly infinite tapestry of galaxies, stars, and planets, each potentially harboring its own secrets. Among these cosmic mysteries, one question looms large over our species: Are we alone? For decades, scientists have combed the skies for signs of intelligent life—searching for radio signals, scanning the electromagnetic spectrum, and pointing laser arrays into the void. Yet, despite the most advanced technologies and tireless efforts, the silence has been deafening.

We all make mistakes. Nobody’s perfect. Not even some of the greatest geniuses in history, as Mario Livio tells us in this marvelous story of scientific error and breakthrough. Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein were all brilliant scientists. Each made groundbreaking contributions to his field - but each also stumbled badly. These five scientists expanded our knowledge of life on Earth, the evolution of the Earth itself, and the evolution of the universe, despite and because of their errors. As Mario Livio luminously explains, the scientific process advances through error.

Quantum theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.

The message of modern physics is that physical reality has, at its frontiers, all the aspects of a transcendent order. At the foundation of things, elementary particles can exert instantaneous long-distance influences on each other, can be meaningfully said to have mind-like properties, and can exist in states which are, as Heisenberg wrote, "not quite real, but between the idea of a thing and a real thing."

Throughout history, thinkers from mathematicians to theologians have pondered the mysterious relationship between numbers and the nature of reality. In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887.... This curious mathematical relationship, widely known as "The Golden Ratio", was discovered by Euclid more than 2,000 years ago. Since then it has shown a propensity to appear in the most astonishing variety of places.

Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light - the core of what we now know as quantum theory - than he did about relativity.

Utterly beautiful. Profoundly disconcerting. Quantum theory is quite simply the most successful account of the physical universe ever devised. Its concepts underpin much of the 21st-century technology that we now take for granted. But at the same time it has completely undermined our ability to make sense of the world at its most fundamental level.

From the contours of coastlines to the outlines of clouds, and the branching of trees, fractal shapes can be found everywhere in nature. In this Very Short Introduction, Kenneth Falconer explains the basic concepts of fractal geometry, which produced a revolution in our mathematical understanding of patterns in the 20th century, and explores the wide range of applications in science, and in aspects of economics.

Since the 1950s, scientists have attempted to harness nuclear fusion—the process that creates the Sun's energy—to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke.

The Physics of Life argues that the evolution phenomenon is much broader and older than the evolutionary designs that constitute the biosphere, empowering listeners with a new view of the globe and the future, revealing that the urge to have better ideas has the same physical effect as the urge to have better laws and better government. This is evolution explained loudly but also elegantly, forging a path that flows sustainability.

E=mc2: It may be Einstein’s most well-known contribution to modern science, but how many people understand the thought process or physics behind this famous equation? In this collection of his seven most important essays on physics, Einstein guides the listener step-by-step through the many layers of scientific theory that formed a starting point for his discoveries.
