The Tetris Effect: Your Brain Can Get Addicted to Patterns

People who play Tetris for extended periods begin seeing falling block patterns in the real world — imagining how objects like books on a shelf or buildings on a street could be rearranged to fit together. This 'Tetris effect' is a broader phenomenon where repeated mental activities begin to unconsciously shape perceptions and thoughts. Lawyers begin seeing liability everywhere, doctors start diagnosing strangers, and accountants unconsciously look for numerical patterns in everyday life.

He oversaw the planning and construction of the city but died in December 1799 — before the federal government officially moved there in 1800. Washington spent most of his life at his plantation, Mount Vernon, located about 15 miles south of the city.

Beneath the U.S. Capitol complex runs a small, dedicated subway system known as the Capitol Subway System. It consists of two underground rail lines connecting the Capitol building to the House and Senate office buildings, allowing lawmakers and their staff to travel quickly between offices without going outside. The system has been in operation since 1909.

The Height of Buildings in Washington D.C. Is Strictly Limited by Law

A common myth claims that no building in D.C. can be taller than the Capitol dome, but the truth is stranger: the 1910 Height of Buildings Act limits most structures to no more than 130 feet (about 40 meters) on commercial streets. This law — not the Capitol's height — is why Washington D.C. has no skyscrapers, giving it one of the most distinctive, flat skylines of any major capital city.
