Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the 20th century. His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius.

Physicist and popular science author Simon Singh explores the numbers and concepts that lie at the heart of some of the trickiest problems in mathematics, revealing their history, significance and unique qualities. Beginning with zero - which, amazingly, wasn't invented until 400 BC and then took thousands of years to catch on - he goes on to serve up a slice of pi, uncover the hidden beauty of the Golden Ratio, reveal the reality behind the imaginary number and explain why some infinities are bigger than others.

In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

Are human beings immortal? Are apples conscious? Do our legal systems make assumptions about free will that are just plain wrong? Of all the terrific books on quantum physics—from Stephen Hawking to Brian Greene—the questions they never seem to satisfy are the implications of the science. We know that quantum physics is real—our phones and computers wouldn’t work if the science wasn’t right. But what does it all mean?

An epic story of science and technology at the very limits of human understanding: the monumental race to build the first atomic weapons.

Rich in personality, action, confrontation, and deception, The First War of Physics is the first fully realized popular account of the race to build humankind's most destructive weapon. The book draws on declassified material, such as MI6's Farm Hall transcripts, coded Soviet messages cracked by American cryptographers in the Venona project, and interpretations by Russian scholars of documents from the Soviet archives.

In Infinite Potential, physical chemist Lothar Schäfer presents a stunning view of the universe as interconnected, nonmaterial, composed of a field of infinite potential, and conscious. With his own research as well as that of some of the most distinguished scientists of our time, Schäfer moves us from a reality of Darwinian competition to cooperation, a meaningless universe to a meaningful one, and a disconnected, isolated existence to an interconnected one.

Quantum physics is the cornerstone of our world, offering a framework so expansive and precise that it underpins nearly every piece of modern technology. Yet, at the same time, it’s one of the hardest subjects to grasp. In Why Nobody Understands Quantum Physics, a leading scientist and a literary mind unite to explain the revolutionary discoveries and astounding phenomena at the heart of quantum physics. From the greenness of grass to the solidity of matter, they unravel why the universe behaves in the peculiar ways it does and why it's so important.

When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices - or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical.

Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

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.

In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe.

Nothing has had a more profound impact on the development of modern civilization than thermodynamics. Thermodynamic processes are at the heart of everything that involves heat, energy, and work, making an understanding of the subject indispensable for careers in engineering, physical science, biology, meteorology, and even nutrition and culinary arts. Get an in-depth tour of this vital and fascinating science in 24 enthralling lectures suitable for everyone from science novices to experts who wish to review elementary concepts and formulas.

During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering an easily understood and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics.

In 2003, Russian physicists Andre Geim and Konstantin Novoselov found a way to produce graphene - the thinnest substance in the world - by using sticky tape to separate an atom-thick layer from a block of graphite. Their efforts would win the 2010 Nobel Prize for Physics, and now the applications of graphene and other two-dimensional substances form a worldwide industry.

The ordinary atoms that make up the known universe - from our bodies and the air we breathe to the planets and stars - constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science - what is the universe made of? - told by one of today’s foremost pioneers in the study of dark matter.

Most of us would agree that Albert Einstein’s name is synonymous with “genius” and that his likeness is often used as a shorthand for all scientists, appearing everywhere from cartoons to textbooks. He has become more myth than man. That being the case, how best to capture his essence? In Einstein in Time and Space, talented young science journalist Samuel Graydon answers that question with an illuminating mosaic—99 intriguingly different particles that cumulatively reveal Einstein’s contradictory and multitudinous nature.

In researching one of history's greatest scientific quests, a mission to measure the Earth and define the meter, Ken Alder stumbled on a 200-year-old secret: The meter, it turns out, is in error. This is a story of two men, a secret, and a timeless human dilemma: is it permissible to perpetuate a small lie in the service of a larger truth?

Napoleon's Buttons is the fascinating account of 17 groups of molecules that have greatly influenced the course of history. These molecules provided the impetus for early exploration, and made possible the voyages of discovery that ensued. The molecules resulted in grand feats of engineering and spurred advances in medicine and law; they determined what we now eat, drink, and wear. A change as small as the position of an atom can lead to enormous alterations in the properties of a substance.

After the Apollo program put 12 men on the moon and safely brought them home, anything seemed possible. In this spirit, the team at NASA set about developing the space shuttle, arguably the most complex piece of machinery ever created.
