Despite Einstein’s amazing test scores, he had a hard time finding work after school. He ended up working as a clerk at a patent office in Switzerland by 1902. Einstein used this time to develop his theorems, which quickly became the principle of relativity. Unlike many scientists who follow the letter of the scientific method, Einstein’s work was written as a gedankenexperiment, or thought-experiment. This combined the scientific method with his own imagination. He used imagination to draw out a scenario and describe the motion of objects in vivid detail. Then he would use mathematic principles to label his imagined scene.

Einstein was able to consider the speed of light and energy in ways that his predecessors could not. Since the Scientific Revolution, many inventions presented new ways of seeing the world. Thanks to photography, X-rays, radium, uranium, and more, people were able to look more deeply into electromagnetism than ever before. These inventions and the discoveries they brought to the world allowed Einstein to rethink the world at its smallest and largest states—the atomic level and in outer space.

Einstein’s special relativity was confusing to many. But a famous physicist, Max Planck, backed Einstein’s assertions. Planck is known as the father of quantum mechanics. His endorsement allowed the young Einstein to continue working and publishing until his theories were proven true. And they continue to be proven true today.

Einstein’s predictions about relativity were first proven true in 1919 during a total solar eclipse. In those days— before digital technology—the scientists had to figure out where they’d be able to observe an eclipse from, needing to consider global positioning and the clearest weather. Overnight, the discovery that, as Einstein predicted, light did in fact bend along space-time as it neared a gravitational origin made him famous.

Stephen Hawking

One of the many phenomena Einstein predicted was the existence of black holes. Black holes were not discovered in Einstein’s lifetime. The famous physicist Stephen Hawking has been able to use Einstein’s work to continue proving the merits of relativity in the context of planetary motion, planetary creation, and other phenomena in space.

Stephen Hawking was born in England in 1942. As a child, like many prodigies, Hawking did not perform well in school. Though he cared little for the rules of school, he was constantly playing and inventing board games, pondering the sky, and generally engaging in introverted, intellectual endeavors. Hawking’s bright mind, despite his lack of studying, got him admission to Oxford by the age of seventeen.

Since Oxford didn’t offer a degree in mathematics at the time, Hawking chose to study physics. He considered himself a cosmologist—a scientist who uses astronomy and physics to study the development of the universe. He went on to Cambridge to get a PhD in cosmology.

At the young age of twenty-one, while at Cambridge, Hawking was diagnosed with amyotrophic lateral sclerosis— better known today as ALS or Lou Gehrig’s disease. The result of this disease is the inability to control or use your muscles. Hawking was given about two years to live.
