Was Albert Einstein A Space Alien?

Einstein's High School Diploma. Contrary to urban legend, Albert did well in school.

For example: the photoelectric effect. This was a puzzle in the early 1900s. When light hits a metal, like zinc, electrons fly off. This can happen only if light comes in little packets concentrated enough to knock an electron loose. A spread-out wave wouldn't do the photoelectric trick.

The solution seems simple - light is particulate. Indeed, this is the solution Einstein proposed in 1905 and won the Nobel Prize for in 1921. Other physicists like Max Planck (working on a related problem: blackbody radiation), more senior and experienced than Einstein, were closing in on the answer, but Einstein got there first. Why?

It's a question of authority.

"In Einstein's day, if you tried to say that light was made of particles, you found yourself disagreeing with physicist James Clerk Maxwell. Nobody wanted to do that," says Galison. Maxwell's equations were enormously successful, unifying the physics of electricity, magnetism and optics. Maxwell had proved beyond any doubt that light was an electromagnetic wave. Maxwell was an Authority Figure.

Einstein didn't give a fig for authority. He didn't resist being told what to do, not so much, but he hated being told what was true. Even as a child he was constantly doubting and questioning. "Your mere presence here undermines the class's respect for me," spat his 7th grade teacher, Dr. Joseph Degenhart. (Degenhart also predicted that Einstein "would never get anywhere in life.") This character flaw was to be a key ingredient in Einstein's discoveries.

"In 1905," notes Galison, "Einstein had just received his Ph.D. He wasn't beholden to a thesis advisor or any other authority figure." His mind was free to roam accordingly.

In retrospect, Maxwell was right. Light is a wave. But Einstein was right, too. Light is a particle. This bizarre duality baffles Physics 101 students today just as it baffled Einstein in 1905. How can light be both? Einstein had no idea.

That didn't slow him down. Disdaining caution, Einstein adopted the intuitive leap as a basic tool. "I believe in intuition and inspiration," he wrote in 1931. "At times I feel certain I am right while not knowing the reason."

Although Einstein's five papers were published in a single year, he had been thinking about physics, deeply, since childhood. "Science was dinner-table conversation in the Einstein household," explains Galison. Albert's father Hermann and uncle Jakob ran a German company making such things as dynamos, arc lamps, light bulbs and telephones. This was high-tech at the turn of the century, "like a Silicon Valley company would be today," notes Galison. "Albert's interest in science and technology came naturally."
