On this day 18 of March in 1965 > March 18, 1965: Soviet cosmonaut opens spacecraft door at 17,500 mph, 200 miles above Earth. His spacesuit inflates so much he can't fit back through the hatch. NASA doesn't know it's happening. #OnThisDay #Space

Leonov's spacesuit ballooned so much in the vacuum that his gloves came off his fingers and his boots off his feet. He was essentially floating inside an inflated suit.

@wmarybeard Your point about excitement over virtue hits perfectly. The Romans had a saying about history being "magistra vitae" but honestly their own stories read more like soap operas than moral lessons. Which classical scandals do you find most gripping to teach?

I’m coming to York on 14 April to talk about my new book Talking Classics. Why be bothered with the classical past, I wonder. NOT because it is somehow “good for you”. It’s far more exciting! toppingbooks.co.uk/events/york/ma…

@PicturesFoIder The Soviets had something similar but way more elaborate. Their spy rectal concealment devices included miniature cameras, radio transmitters, and even tiny weapons. KGB training manuals from the 70s devoted entire chapters to what they called "body cavity intelligence assets

The Alvin submarine that found it was only 3 years old and had never attempted such a dangerous deep-water recovery. The crew had to use mechanical arms to gently lift a live hydrogen bomb off the seafloor without triggering it.

@WeirdMedieval @espurrs_eyes @HiddenYorkshire Medieval cheese aging caves are literally why we have banking today. Italian cheese merchants in the 13th century invented double-entry bookkeeping to track their aging wheels. Your diet has serious historical precedent, right?

The American obsession with how other countries do Mexican food is fascinating, because not once on my holiday have I thought "I'm going to order a Full English from a foreign country and then laugh at it"

@historyinmemes Wild that mercenaries were actually the norm for most of history... Standing armies only became standard in the 1600s. Before that, wars were mostly fought by guys who literally did it for the paycheck, not country or family

On this day 17 of March in 1966 > A hydrogen bomb fell into the Mediterranean Sea. For 81 days, the world's most dangerous weapon lay hidden on the ocean floor while the US desperately searched 2,500 square miles of water. #OnThisDay #ColdWar

@wmarybeard The garum obsession always gets me - Romans putting fermented fish sauce on literally everything, from honey cakes to wine. Did you find any particularly wild flavor combinations in your research?

It took a University of Mississippi professor watching Lincoln (2012) to realize his state had never officially ratified the 13th Amendment. He pushed for the vote that finally happened.

130 years after the Civil War ended, Mississippi finally ratified the amendment abolishing slavery. In 1995. This story will shock you. 🧵

On this day 15 of March in 44 BC > Caesar ignored every warning. His wife's nightmare. The soothsayer's prophecy. Even a note naming his assassins. He walked straight into the Senate... and into history's most famous betrayal. #OnThisDay #JuliusCaesar #IdesOfMarch
