Engineering Physics

When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories. But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories—relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang?

One of our great contemporary scientists reveals the 10 profound insights that illuminate what everyone should know about the physical world.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

How to Love the Universe is a new kind of science writing by an author truly enamored of the world around him. In 10 short chapters of lyrical prose - each one an ode to a breathtaking realm of discovery - Stefan Klein uses everyday objects and events as a springboard to meditate on the beauty of the underlying science.

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

Is there such a thing as a fundamental reality, something which was around before our universe came into existence and which will still remain when all matter, time, and space itself ultimately disappear? Something fundamental which, in turn, can make space and time and matter arise from seemingly nothing? Under most cosmological and physical models, the last known remnants of reality are the disembodied laws of mathematics - beyond which it is extremely difficult to probe further.

In this groundbreaking classic, investigative journalist Lynne McTaggart reveals a radical new paradigm - that the human mind and body are not separate from their environment but a packet of pulsating power constantly interacting with this vast energy sea, and that consciousness may be central in shaping our world. The Field is a highly listenable scientific detective story presenting a stunning picture of an interconnected universe and a new scientific theory that makes sense of supernatural phenomena.

Stephen Hawking’s worldwide best seller A Brief History of Time remains a landmark volume in scientific writing. But for those who have asked for a more accessible formulation of its key concepts - the nature of space and time, the role of God in creation, and the history and future of the universe - A Briefer History of Time is Professor Hawking’s response.

In When the Uncertainty Principle Goes to 11, physicist Philip Moriarty explains the mysteries of the universe's inner workings via drum beats and feedback: You'll discover how the Heisenberg uncertainty principle comes into play with every chugging guitar riff, what wave interference has to do with Iron Maiden, and why metalheads in mosh pits behave just like molecules in a gas.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

When and how did the universe begin? Why are we here? What is the nature of reality? Is the apparent “grand design” of our universe evidence of a benevolent creator who set things in motion—or does science offer another explanation? In The Grand Design, Stephen Hawking and Leonard Mlodinow present the most illuminating scientific thinking about these and other abiding mysteries of the universe, in nontechnical language marked by brilliance and simplicity.

How many people achieve a cult following because of their writing in mathematics? Only a handful, and Martin Gardner is among the most well-known and well-loved. Not only did he present a notoriously difficult subject in an engaging and accessible way, but in doing so, he attracted an incredibly broad readership. His “Mathematical Games” column in Scientific American ran nearly every month for 26 years and was one of the most popular in the magazine’s history.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

In Signposts to God, particle physicist Peter Bussey introduces listeners to the mysteries of modern physics and astronomy. Authored in clear, accessible prose, Bussey provides a primer on topics such as the laws of nature, quantum physics, fine-tuning, and current cosmological models. Bussey argues that, far from ruling out a divine creator, modern physics and astronomy present us with compelling signposts to God. The more we know about the cosmos and our presence in it, the more plausible belief in God becomes.

Whether it is true or not that not more than 12 persons in all the world are able to understand Einstein's Theory, it is nevertheless a fact that there is a constant demand for information about this much-debated topic of relativity. The books published on the subject are so technical that only a person trained in pure physics and higher mathematics is able to fully understand them. In order to make a popular explanation of this far-reaching theory available, the present book was written.

The atom, the big bang, DNA, natural selection - all are ideas that have revolutionized science; and all were dismissed out of hand when they first appeared. The surprises haven't stopped in recent years, and in At the Edge of Uncertainty, best-selling author Michael Brooks investigates the new wave of radical insights that are shaping the future of scientific discovery.

In this absorbing and frequently contentious book, Roger Penrose puts forward his view that there are some facets of human thinking that can never be emulated by a machine. The book's central concern is what philosophers call the "mind-body problem". Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness.

The Skeptics' Guide to the Universe is your map through this maze of modern life. Here Dr. Steven Novella and friends will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies, and conspiracy theories - from anti-vaccines to homeopathy, UFO sightings to N-rays. You'll learn the difference between science and pseudoscience, essential critical thinking skills, ways to discuss conspiracy theories with that crazy co-worker of yours, and how to combat sloppy reasoning, bad arguments, and superstitious thinking.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding.
