Einstein’s theory of special relativity

Special relativity, formulated by Einstein, describes how space and time are linked for objects moving at constant speeds. It states that the speed of light is constant for all observers, leading to time dilation (moving clocks run slower), length contraction (moving objects shrink), and mass-energy equivalence (E = mc²). This video breaks down how motion and time are fundamentally related.

Albert Einstein's equations predicted black holes decades before their discovery

For nearly 50 years, scientists dismissed black holes as implausible oddities, despite solutions to the equations indicating their existence. But the 1970s discovery of intense X-rays from Cygnus X-1 and its massive hidden companion flipped the consensus.

Einstein warned the president that splitting atoms could lead to powerful bombs

In a 1939 letter to Franklin D. Roosevelt, Albert Einstein explained that nuclear fission could produce immense energy—and devastating weapons. The warning helped spur the Manhattan Project, a role Einstein later deeply regretted.

Zurich's Cabaret Voltaire was the epicenter of early performance art

In early 20th-century Zurich, one nightclub was the epicenter of avant-garde art and performance: Cabaret Voltaire. Night after night, crowds of artists, writers, philosophers, and others would gather to watch—or participate in—wild, unrehearsed performances that could include anything from sound poems to traditional folk dance. The atmosphere at Club Voltaire was the ideal breeding ground for outside art movements, and it is thought to be the birthplace of Dada, a precursor to performance art.

Exploring the White City of Tel Aviv, the capital of the Bauhaus style

In 1933, around 60,000 German Jews fled the Nazi regime for what was then Mandatory Palestine. Among them were six Bauhaus students, who accommodated the influx by working with nearly 150 other architects to design over 4,000 buildings that reflected their alma mater's modernist style. This Smarthistory article on the area, now a UNESCO World Heritage site, allows you to see several of its buildings from the comfort of your couch.
