To visualize the unseen

According to renowned biographer, Walter Isaacson, when Albert Einstein’s younger son, Eduard, asked why he was so famous, Einstein replied by using one of his famed thought experiments to describe his insight that gravity was the curving of the fabric of space-time.

“When a blind beetle crawls over the surface of a curved branch, it doesn’t notice that the track it has covered is indeed curved,” he said. “I was lucky enough to notice what the beetle didn’t notice.”
