String Theory

In 2000, Martin Bojowald, then a 27-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a cunning combination of Einstein’s theory of gravity with quantum mechanics - to create a simple model of the Universe....

Modern physics studies the four “known forces” of nature: gravity, electromagnetic, weak, and strong nuclear forces. However, “known forces” is a misnomer because hundreds of years of investigation have not led to any clearer understanding....

In Astronomy’s Limitless Journey, astrophysicist Günther Hasinger takes the reader on a journey to the far reaches of the universe?an exciting time travel that begins with the incredibly hot fireball of the Big Bang roughly 13.8 billion years ago and ends in distant eons with its cold, dark demise. In between lie the times in which extensive structures, galaxies, stars, and planets form....

In the ever-fascinating Why? Mario Livio interviewed scientists in several fields to explore the nature of curiosity....

The "universe" refers to all "observable things", ranging in size from the entire cosmos to elementary particles. A guide for an enjoyable visit to the universe, this small tome on fundamental physics, cosmology, Higgs bosons, time travel, and all that is unlike any other analogous book....

Imagine time as the force driving existence, rather than just a procession of events. How can that concept enhance how we regard science, religion, philosophy, and our daily living? Review the possibilities presented in this audiobook. Then you decide....

In this audio summary of The Order of Time, theoretical physicist Carlo Rovelli explores the very nature of time, physics, humanity, and philosophy in a book that challenges our perceptions of the world around us....

For the past 15 years, acclaimed science writer Margaret Wertheim has been collecting the works of "outsider physicists"....

An accessible look at the hottest topic in physics and the experiments that will transform our understanding of the universe.....

In June of 1916, Albert Einstein published his ambitious paper proposing the existence of gravitational waves....

Alan Gross reveals the modern-day sublime in popular science. He tells how the great popular scientists of our time evoke the sublime in response to fundamental questions about the universe and the origin of life....

In 2013 scientists made a remarkable discovery that was hailed worldwide as a triumph of human ingenuity. Using a massive machine called a particle accelerator....

Why the Universe Exists takes you deep into the world of particle physics to explore how the universe functions at the smallest scales....

In recent years, scientists have hypothesized life-forms that can only be called "weird"....

The commonly held view of Albert Einstein is of an eccentric genius for whom the pursuit of science was everything. But in actuality, the brilliant innovator whose Theory of Relativity forever reshaped our understanding of time was a man of his times....

Covers everything from the nature of scientific inquiry, experimenter's regress, and why the dinosaurs were so big, to relativity, the Higgs boson, and the Rope Hypothesis....

On the night of March 26, 1938, nuclear physicist Ettore Majorana boarded a ship, cash and passport in hand....

Dark matter remains one of the most captivating mysteries of the universe, challenging scientists and enchanting the imagination of the public. ...

Even in the 21st century, the popular image of a scientist is a reclusive genius in a lab coat, mixing formulas or working out equations inaccessible to all but the initiated few....

For all of you who break out in a sweat at the thought of thermodynamics, or freeze up at the mention of quantum mechanics, like a bolt from the ...
