Rose de Freycinet – artist?
Rose de Freycinet was certainly no artist, to judge from the only drawing possibly by her that is readily accessible, but she did have many other qualities and abilities, as revealed in her letters to her mother.
Railroad Rand (5: The miner)
Ayn Rand believed that all government was evil. So evil, in fact, that even borrowing money from it to buy a business was a sin that deserved a death sentence.
A very smart scientist
One milligal is approximately one millionth of the Earth’s gravity field, so it would seem that the periods of pendulums used for measuring gravity would have to be measured to a few millionths of a second for the results to be useful. This was simply not possible in the early nineteenth century, but pendulums were being used then to obtain results accurate to a few tens of milligal. How was it done?
The Elder Brother
Louis de Freycinet had an elder brother, Henri,, and the two brothers joined the French navy on the same day in 1794. On the face of it, Henri had the more successful career, administering three colonies in succession, reaching the rank of Rear Admiral and becoming a baron. But it is Louis who is better remembered.
The armed libertarian
Ayn Rand thought that governments were not to be trusted, and the world would be a better place if they didn’t exist, but she still thought an army to be a necessity. More extreme libertarians disagree. They want lots of them.
Alejandro Malaspina and the first global gravity survey
Between April 1791 and January 1794, officers of Alejandro Malaspina’s mission to the Pacific measured gravity at no fewer than 17 different locations. It was the first truly global gravity survey, but how accurate was it?
