On this day in 1800, Alessandro Volta wrote a letter to the Royal Society of London describing a stack of metal discs and salty cloth that could produce electricity continuously. No sparks. No static. Just steady current, on demand. A thread 🧵

Today the bridge sits at the center of one of the most watched New Year's Eve celebrations on earth. It is 94 years old, still the tallest steel arch bridge on the planet, and was paid off by the time most of its builders were already dead. Not a bad run for a coathanger.

The bridge cost so much that tolls were collected for 56 years to service the debt, finally paid off in 1988, Australia's Bicentennial year. On hot days the arch expands and the top rises about 18 cm. Engineers knew this would happen and designed for it.

Leonov survived to command Soyuz 19 in 1975 and shook hands with American Tom Stafford in orbit during Apollo-Soyuz. The man who won the first lap of the Space Race helped close it. He died in 2019, aged 85. The first human to walk in space was also the first to make art there.

Soviet TV quietly cut the live broadcast mid-mission. The real story stayed hidden for decades. Leonov publicly said working in weightlessness was easy, the opposite of the truth. The near-disasters were so serious the Soviets wouldn't attempt another EVA for almost four years.

On this day in 1965, a Soviet cosmonaut climbed out of a spacecraft 500 kilometers above Earth and floated in open space for the first time in human history. It nearly killed him in three different ways. A thread 🧵

On this day in 1988, Apple sued Microsoft for stealing the look and feel of the Mac. It was the biggest copyright fight in tech history and Apple lost almost everything. A thread 🧵

@TodayInTechHist I have always wondered about that photo which part of it flies, which part belongs to the launching pad.

On this day 100 years ago, a physics professor launched a spindly rocket from a snow-covered farm in Massachusetts. It flew for 2 seconds and reached 41 feet. Nobody covered it. It changed everything. A thread 🧵
