Wilbur and Orville Wright also used the internal-combustion engine to free people from earthly bounds. Their 12-second flight in 1903 transformed both war and peace. As Bill Gates said in these pages, "Their invention effectively became the World Wide Web of that era, bringing people, languages, ideas and values together." The result was a new era of globalization...
During his spare time as a young technical officer in a Swiss patent office in 1905, he produced three papers that changed science forever. The first, for which he was later to win the Nobel Prize, described how light could behave not only like a wave but also like a stream of particles, called quanta or photons. This wave-particle duality became the foundation of what is known as quantum physics. It also provided theoretical underpinnings for such 20th century advances as television, lasers and semiconductors...
...matter were merely different faces of the same thing, their relationship described by the most famous equation in all of physics: energy equals mass multiplied by the speed of light squared, E=mc2. Although not exactly a recipe for an atomic bomb, it explained why one was possible. He also helped resolve smaller mysteries, such as why the sky is blue (it has to do with how the molecules of air diffuse sunlight...
...Einstein also continued his contributions to quantum physics by raising questions that are still playing a pivotal role in the modern development of the theory. Shortly after devising general relativity, he showed that photons have momentum, and he came up with a quantum theory of radiation explaining that all subatomic particles, including electrons, exhibit characteristics of both wave and particle...
Even now scientists marvel at the daring of general relativity ("I still can't see how he thought of it," said the late Richard Feynman, no slouch himself). But the great physicist was also engagingly simple, trading ties and socks for mothy sweaters and sweatshirts. He tossed off pithy aphorisms ("Science is a wonderful thing if one does not have to earn one's living at it") and playful doggerel as easily as equations. Viewing the hoopla over him with humorous detachment, he variously referred to himself as the Jewish saint or artist's model. He was a cartoonist...
