This book is short, but dense. Squeezing the whole history of physics from antiquity to the present in a few pages makes it a whirlwind tour. As an educated layperson, but not a scientist, some of the actual science was beyond me. I blipped over the formulas. But this is the short version of the short history.
Physics began when people began asking questions about the nature of the world around them. What are the stars? What is water? What is air? How do things work the way they do, and why? The first physicist were the Greek philosophers. In the academies they did more thinking than experimenting, but they contemplated the elements, the heavens, motion and what caused it. Aristotle in particular tried to systemize knowledge about the physical world into his own Theory of Everything, for which he would be revered by intellectuals for years to come.
The Romans sought out the Greeks as sources of information. After the fall of Rome, the center of intellectual life shifted to the Islamic world, and many texts of philosophy were translated into Arabic, where they were called falsafa. The Muslims made progress studying astronomy and mechanics, and the invention of the astrolabe was one of their crowning achievements.
Europe began to emerge from the Dark Ages, and founded universities, and the great philosophical and scientific texts were translated again, from Arabic to Latin. Progress was made in astronomy, leading to Galileo's famous conflict with the church. (Islamic scholars had sometimes had a similar problem with their own religious leaders, as the skeptical, questioning basis of science has sometimes been seen as an affront to those who believe in an obedient faith.) Other gains in Europe had to do with the needs of navigation, and growing business and industry.
The Enlightenment set science free to experiment. The famous names of Descartes and Newton appear. Scientific societies were formed, giving public lectures, and public displays of electricity, magnetism, and the properties of gases.
In the 19th century, the famous names come faster and furiouser: Faraday, Maxwell, Kelvin, Rutherford, the Curies, Bohr, with the discovery of the properties of atoms, and the periodic table.
In the 20th century, the US becomes the center of physics, especially as many European scientists sought refuge from the war, including Einstein. More knowledge of atomic particles followed, and the development of quantum theory. Computers, big telescopes, particle colliders, and other big machines
became the drivers of physics.
In the last chapter Heilbron takes us back to the philosophical beginning. What does everything mean? What is the humanity's place in the grand scheme of things? It doesn't look good, as the universe is huge, and indifferent, and our sun will burn itself out, and we will all die, but if we search and ask questions we will see what we can do.
Some have complained that the writing style of this book is too difficult. Heilbron does have an above-average vocabulary, with words like adumbrated, congeries, stultification, and vituperation. But I have an above-average vocabulary, too, so I didn't mind. And within that wordy frame, the style is surprisingly jaunty. Heilbron packs in the facts, but often with a light touch, even making little jokes sometimes (which, unfortunately I don't have any examples of).
