he produced the special theory of relativity in 1905. Called “On the Electrodynamics of Moving Bodies,” it is one of the most extraordinary scientific papers ever published, as much for how it was presented as for what it said. It had no footnotes or citations, contained almost no mathematics, made no mention of any work that had influenced or preceded it, and acknowledged the help of just one individual, a colleague at the patent office named Michele Besso. It was, wrote C. P. Snow, as if Einstein “had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done.” His famous equation, E=mc2, did not appear with the paper, but came in a brief supplement that followed a few months later. As you will recall from school days, E in the equation stands for energy, m for mass, and c2 for the speed of light squared. In simplest terms, what the equation says is that mass and energy have an equivalence. They are two forms of the same thing: energy is liberated matter; matter is energy waiting to happen. Since c2 (the speed of light times itself) is a truly enormous number, what the equation is saying is that there is a huge amount—a really huge amount—of energy bound up in every material thing.*18 You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 x 1018 joules of potential energy—enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point. Everything has this kind of energy trapped within it. We're just not very good at getting it out. Even a uranium bomb—the most energetic thing we have produced yet—releases less than 1 percent of the energy
A Short History of Nearly Everything

Through hard work and Patti’s great love I have overcome much of this, though not all of it. I have days when my boundaries wobble, my darkness and the blues seem to beckon and I seek to medicate myself in whatever way I can. But on my best days, I can freely enjoy the slow passing of time, the tenderness that is in my life; I can feel the love I’m a part of surrounding me and flowing through me; I am near home and I am standing hand in hand with those I love, past and present, in the sun,

The Revolution Becomes a European War Howe’s triumph at Germantown and his seizure of Philadelphia gave satisfaction to the British government, but these events did not lift the depression that had set in when information about Burgoyne’s capture arrived. The term inevitably attached to that event was “disaster.” Just how disastrous the loss of Burgoyne’s army was could not be known immediately, and for several months there was hope in the cabinet that its worst consequence could be avoided. What the cabinet feared was the entrance of France into the war on the side of the American colonies. French action against Britain would transform a rebellion within the empire into a worldwide conflict whose spread would necessarily result in the dispersion of British forces—and almost inevitably the establishment of American independence. Since 1763 the French had husbanded their outrage and dreamed of revenge against the British for the defeat they suffered in the Seven Years War. Not surprisingly, the upheavals in the British colonies alerted the French government to the possibility of splintering the British empire. Choiseul, the foreign minister of Louis XV, recognizing that much of Britain’s strength lay in her colonies and trade with them, watched the rising American disaffection with hope that war would occur. Choiseul, however, also had other problems to think about, for example, how he was going to rebuild French naval and military power. This problem existed because of another—a treasury depleted by the Seven Years War. The agents he sent to America in the 1760s sent back opinions that rebellion would occur, but not immediately, an assessment Choiseul accepted without question.1
