For many of us, the physical sciences are as obscure as the phenomena they explain. We see the wonders of nature but miss the symmetry beneath, framed as it is in ever stranger symbols and concepts. Roger Newton's accessible account of how physicists understand the world allows the expert and novice alike to explore both the mysteries of the universe and the beauty of the science that gives shape to the unseeable.

In What Makes Nature Tick? we find engaging discussions of solitons and superconductors, quarks and strings, phase space, tachyons, time, chaos, and indeterminacy, as well as the investigations that have led to their elucidation. But Roger Newton does not limit this volume to late-breaking discoveries and startling facts. He presents physics as an expanding intellectual structure, a network of very human ideas that stretches back three hundred years from our present frontier of knowledge. Where does our unidirectional sense of time come from? What makes a particle elementary? How can forces be transmitted through empty space? In addition to providing these answers, and a host of others at the very heart of physics, Newton shows us how physicists formulate the questions--a process in which intuition, imagination, and aesthetics have a powerful influence.

The history of science is replete with women getting little notice for their groundbreaking discoveries. Cecilia Payne-Gaposchkin, a tireless innovator who correctly theorized the substance of stars, was one of them.

It was not easy being a woman of ambition in early twentieth-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called “the most brilliant PhD thesis ever written in astronomy,” she was the first to describe what stars are made of.

Payne-Gaposchkin lived in a society that did not know what to make of a determined schoolgirl who wanted to know everything. She was derided in college and refused a degree. As a graduate student, she faced formidable skepticism. Revolutionary ideas rarely enjoy instantaneous acceptance, but the learned men of the astronomical community found hers especially hard to take seriously. Though welcomed at the Harvard College Observatory, she worked for years without recognition or status. Still, she accomplished what every scientist yearns for: discovery. She revealed the atomic composition of stars—only to be told that her conclusions were wrong by the very man who would later show her to be correct.

In What Stars Are Made Of, Donovan Moore brings this remarkable woman to life through extensive archival research, family interviews, and photographs. Moore retraces Payne-Gaposchkin’s steps with visits to cramped observatories and nighttime bicycle rides through the streets of Cambridge, England. The result is a story of devotion and tenacity that speaks powerfully to our own time.

A crystal-clear, scientifically rigorous argument for the existence of free will, challenging what many scientists and scientifically minded philosophers believe.

Philosophers have argued about the nature and the very existence of free will for centuries. Today, many scientists and scientifically minded commentators are skeptical that it exists, especially when it is understood to require the ability to choose between alternative possibilities. If the laws of physics govern everything that happens, they argue, then how can our choices be free? Believers in free will must be misled by habit, sentiment, or religious doctrine. Why Free Will Is Real defies scientific orthodoxy and presents a bold new defense of free will in the same naturalistic terms that are usually deployed against it.

Unlike those who defend free will by giving up the idea that it requires alternative possibilities to choose from, Christian List retains this idea as central, resisting the tendency to defend free will by watering it down. He concedes that free will and its prerequisites—intentional agency, alternative possibilities, and causal control over our actions—cannot be found among the fundamental physical features of the natural world. But, he argues, that’s not where we should be looking. Free will is a “higher-level” phenomenon found at the level of psychology. It is like other phenomena that emerge from physical processes but are autonomous from them and not best understood in fundamental physical terms—like an ecosystem or the economy. When we discover it in its proper context, acknowledging that free will is real is not just scientifically respectable; it is indispensable for explaining our world.
