Albert Einstein developed his theory of special relativity in 1905, and then mentally mapped out his theory of general relativity between 1907 and 1915. For years to come, the rest of the world would try to catch up with Einstein, trying to understand the gist, let alone the full implications, of his groundbreaking ideas.
Above, you can watch one such attempt. Produced by Max and David Fleischer, best known for their Betty Boop and Superman cartoons, The Einstein Theory of Relativity used the power of animation to explain relativity to a broad, non-scientific audience in 1923.

In the weeks before he died, Stephen Hawking wrote what would be his final theory of the cosmos. Co-written with Belgian physicist Thomas Hertog, and now published in the Journal of High Energy Physics, “A smooth exit from eternal inflation?”asserts that “reality may be made up of multiple universes, but each one may not be so different to our own.” Or so that’s how the theory gets translated into colloquial English by The Guardian. You can read an abstract of the theory here, or the complete published version here.
As Japan marks the 70th anniversary of the atomic bombings by the United States, it’s well worth returning to the seminal article that laid the horrors of nuclear warfare before the world. John Hersey’s meticulous recreation of the moment the bomb hit Hiroshima, and his intertwined tales of victims,survivors and a shaken country, holds up 69 years after it was published.
