- Shady & Shaky New Material Tangent: French astronomer Guillaume Le Gentil tried to observe the transit of Venus in the late 18th century for the Royal Academy of Sciences. He went to India to see the transit in 1761. However, he got held up in Mauritius for a year due to a war between Britain and France; he was blown off course for five weeks by monsoon winds; the place he wanted to go, Pondicherry, was conquered by the British so he could not land there; meaning on the day of the transit he was still at sea and he could not carry out precise measurements. He thus decided to stay in India for eight years so he could measure the next transit in 1769, but when that transit happened it was cloudy and could not observe it. After this he was in shock for two weeks, almost unable to speak, then he got dysentery.

In some states, it was illegal for women to be strip-searched, so they would provoke officers by telling them that booze was hidden in their bra, and then threaten to sue the officers if they searched them. Two prohibition agents, Isidor "Izzy" Einstein and Moe Smith, specialised in costumed disguises. They would arrive at the scene of the crime as German pickle packers or Hungarian violinists, and Einstein would sometimes as a double-bluff said he was a prohibition agent, which the barman thought was hilarious and let him into this bar.
