Jonas Moore

Laws of Sine and Cosine

By: Rachel Bruijns On February 8th, 1617 at Higher Whitelee in Pendle, Lancashire, Sir Jonas Moore was born. Jonas, though inclined to mathematics as a young boy, does not have a record of an education. Most likely he attended Burnley Grammar School, located three miles from his farmhouse. Jonas lived alongside his yeoman father on their humble farm until 1637, when Thomas Burwell appointed Jonas his clerk. In 1638 Moore married Eleanor Wren in Durham, he later became a father to two daughters and a son.

The events leading to the English Civil War flattened any hope left for Moore to attain a job in parliament. But Moore’s luck changed in 1646 when Charles I sent for him and granted him employment tutoring the Duke of York. Moore published his first book, Moores Arithmetick, as an established math teacher by 1650. Later that year Moore was appointed the Surveyor Earl of Bedford the 5th’s Fen drainage company where he worked for seven years draining the Fenland landscape of East Anglia. Moore later produced a 16 sheet map of the Great Level of the Fens. Providing a visual display of the company’s efforts and achievements to modify the Fenland landscape.

Moore being appointed Assistant Surveyor of the Ordnance 1665 became Surveyor General after the death of Nicholls 1669. Due to Jonas Moore’s growing wealth and influence as Surveyor General he became patron of the new Royal Observatory in Greenwich. During the third Dutch War many burdens were placed upon the office, and by meeting these requests Moore earned the privilege of knighthood in 1673. Moore later founded the Royal Society in 1675 alongside many other influential men. After being made governor of Christ’s Hospital in 1676, Moore subsequently became involved with the management of the Royal Mathematical School. After many fever fits during a land survey, Sir Jonas Moore died a leading mathematician, surveyor, cartographer, Ordnance Officer, courtier and patron of astronomy at the age of sixty-two in 1679.

Hey Rachel,
Great looking list of sources you got there…just curious as too which one is the magazine article…hope you didn't forget that requirement. Thanks for the critique, the verb "to be" is pretty much my english flaw. I like the articel but there are a couple things that I'm curious about:
1.) What do you mean when you say Moore can be "connected" to the cosine formula and sine ratio?
2.) What do you mean when you say Moore "Founded" cos, the abbreviation for cosine and sin, the abbreviation for sine? Is he responsible soley for their abbreviation?
3.) What is a Yeoman? I think I'll look it up and post it's deffinition as a reply to this comment for anyone else who is curious.
At the beginning of paragraph two you say "The events leading to the English Civil War flattened any hope left for Moore to attain a job in parliament" but prior to that you don't tell us that Moore is at all interested in politics.

heres a link to the definition of "yeoman" — The Thesaurus contains a good definition

The biography itself is very well written and easy to follow. You certainly succeeded in getting the feeling of some of his life across: "..War flattened any hope left.." Poor guy!

The only bobble I noticed as far as grammar goes is the sentence "Moore being appointed.." Weird tense. A nod to what Arend had to say.

Your equations look good - familiarity is great!

Good job, Rachel.

I was born in the fenlands of East Anglia :)

Like Jake, I'd like to know what you mean when you say Moore can be connected to the sine and cosine laws. Does that mean he came up with them?
