...moving toward or away from a source of light, the speed of that light beam will appear the same, a constant 186,000 miles per second. But space and time will appear relative. As a train accelerates to near the speed of light, time on the train will slow down from the perspective of a stationary observer, and the train will get shorter and heavier. O.K., it's not obvious, but that's why we're no Einstein...
...Irish physicist George FitzGerald and the Dutch physicist Hendrik Lorentz were the first to suggest that bodies moving through the ether would contract and that clocks would slow. This shrinking and slowing would be such that everyone would measure the same speed for light no matter how they were moving with respect to the ether, which FitzGerald and Lorentz regarded as a real substance...
...others, to make them believe that if they pulled together, everything would turn out all right. The source of this remarkable confidence can be traced to his earliest days. "All that is in me goes back to the Hudson," Roosevelt liked to say, meaning not simply the peaceful, slow-moving river and the big, comfortable clapboard house but the ambiance of boundless devotion that encompassed him as a child. Growing up in an atmosphere in which affection and respect were plentiful, where the discipline was fair and loving, and the opportunities for self-expression were abundant, he came to trust...
When Gutenberg entered it, printing was a slow and laborious business. Each new page required the creation of a new printing form, usually an incised block of wood. He began looking for ways to make metal casts of the individual letters of the alphabet. The advantages of such a method were obvious, or must have been to Gutenberg. Equipped with a sufficient supply of metal letters, a printer could use and reuse them in any order required, running off not just handbills and brief documents but a theoretically infinite number of individual pages. There were technical obstacles to overcome, including...
Standing in an unstable universe where distances contract and clocks slow down, and time and space are plastic, Albert Einstein cast a wistful backward glance at Isaac Newton. "Fortunate Newton, happy childhood of science!" he wrote. "Nature to him was an open book, whose letters he could read without effort...
