In the early 19th century, they tried selling soap as healthy. No one bought it. They tried selling it as sexy, and everyone bought it. – Rose George
The most popular song in the US in 1800 was Amazing Grace.
Anyone in England who unsuccessfully attempted suicide faced the death penalty.

“It is unworthy of excellent men to lose hours like slaves in the labour of calculation which could safely be relegated to anyone else if machines were used.
(Describing, in 1685, the value to astronomers of the hand-cranked calculating machine he had invented in 1673.)”
― Gottfried Wilhelm Leibniz
English scientist William Gilbert coined the word electricus after careful experiments.
Microsoft Windows Epoch time is set to start on January 1, 1601. The Gregorian calendar operates on a 400-year cycle, and 1601 is the first year of the cycle that was active at the time Windows NT was being designed. In other words, it was chosen to make the math come out nicely.
The word “computer” was first recorded as being used in 1613 and was initially used to describe a person who performed calculations or computations. The definition of a computer remained the same until the end of the 19th century when it began referring to a machine that performed calculations.
Frances Blaise Pascal invents the machine, called the Pascaline, that can add, subtract, and carry between digits.
Gottfried Leibniz demonstrates binary arithmetic, a discovery that shows every number can be represented by 0 and 1 only.
If you stop at general math, you’re only going to make general math money. – Snoop Dogg
Snoop is right. If I want to learn about computing and perhaps make some money on the side, I need to sharpen my math skills.
I have started a review of good old arithmetic. More on that later.
By about 2000 BCE, the Babylonians and the Egyptians were pretty good at arithmetic as well as geometry, and some proto-algebra, after all, the Egyptians build the pyramids. Although neither of these civilizations used our current base-10 system, they were practiced enough to turn out solutions to Pythagorean’s theorem referenced in the Plimpton 3221, a clay tablet dated to 1800 BCE. Interestingly, this document was written administratively for something like civil engineering and not something a mathematician would compose. Still cool though.
Mathematics is not something that you find lying around in your back yard. It’s produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle physics and astrophysics, areas of fundamental science that are very, very far removed from everyday affairs.” What does that imply? “It suggests to me that consciousness and our ability to do mathematics are no mere accident,no trivial detail, no insignificant by-product of evolution. – Paul Davies, “Are We Alone?”
