Colin Maclaurin:

Colin Maclaurin was said to be “…a kindly and approachable man…” He contributed to astronomy, cartography, and did actuarial computation for insurance companies.

**Background Information:**

Colin was born in Kilmodan, Argyllshire, February 1698. When his father died six weeks after his birth, his mother moved her and her two sons to Dumbarton where the boys would be able to attend school and have a good education. Colin attended Glasgow University at age eleven which was not unusual for young men in Scotland at the time.

**Career:**

At the age of 19, Colin was elected a professor at the University of Aberdeen. He taught there for a few years. Then, without notice, decided to tour around Europe for two years with a friend. After returning to discover that the University was very displeased with Colin’s actions, he decided to try to become a joint professorship with James Gregory at the University of Aberdeen. Newton, a friend of Colin, supported him personally and financially. Newton even sent him a letter and wrote:

"I am very glad to hear that you have the prospect of being joined with Mr James Gregory in the Professorship of Mathematics at Edinburgh, not only because you are my friend, but principally because of your abilities, you being acquainted as well with the improvements of Mathematics as with the former state of those sciences. I heartily wish you good success, and shall be very glad to hear of your being elected."

Colin began his appointment to the University of Edinburgh November 3, 1725 where he spent the rest of his career. The Treatise of Fluxions was the first logical and systematic exposition of the method of fluxions. In this book, Colin gave a proof of the theorem that:

(1)**Works:**

Colin's cheif works include Geometria Organica, which he published in 1720 while at Aberdeen. De in 1742, he published Treatise on Fluxions, which was “the first systematic exposition of Newton's methods”. Colin also wrote Algebra, and Account of Newton’s Discoveries, Linearum Geometricarum Proprietatibus,

He died in 1746 in Edinburgh and was “buried in Greyfriars Church where his grave can still be seen at the south-west corner”.

Very well written. Interesting mathmatician, the biography was well stuctured and organized. Another piece of info I found interesting

on your mathmatician was that he published the first systematic exposition of Newton's methods. A variety of different sources as well.

ReplyOptionsVery well done. I liked the use of the headings for each section and liked the quotes. I think you may have missed the bold text on the heading "Works:", other then this great job.

ReplyOptionsNice job on this. It was very well organized and written. It's interesting how young your mathematician was when he started studying at university, and how young he was getting his degrees. Another piece of information i found inteserting about your mathematician was that he was only 14 when he came up with a thesis that developed Newton's theories.

ReplyOptionsNice biography! It was very well organized. I liked how you used titles to separate the different sections of your biography. It's hard to believe that someone could be elected a proffessor at the young age of 19. Again, very nice biography.

ReplyOptionsNice biography. I want to read more about Mr. Maclaurin.

Fluxions are cool. We'll be studying them next—except they aren't called fluxions any more. Some more info on the equation would have been helpful.
