  1. Charles Lutwidge Dodgson By: Shakayla Lambert Algebra II P.10

  2. Charles Dodgson’s Background • He’s also known as Lewis Carroll • Born: January 27, 1832 • Died: January 14, 1898 • Birthplace: Cheshire, England, UK • Dodgson was the eldest son and third child in a family of seven girls and four boys. His dad was a Reverend in a church. • The Dodgson lived in a isolated country village. He mostly played with his brothers and sisters and created games for his whole family to play. • He was ordained as a deacon in the Church of England. • He is best known for writing “Alice in Wonderland.” Nonetheless, many don’t‘ realize that he was an accomplished mathematician.

  3. Education • When he was in elementary and middle school he was bullied. He didn’t have many friends because he was shy. Dodgson endured several illness as a child, one of which left him deaf in one year. • Dodgson attended at Church Christ College in Oxford, England. • He excelled in his mathematical and classical studies while he was in college. • Dodgson was nominated to a studentship, which is a scholarship that rewards you for getting good grades in school. • While at Church Christ College, he was appointed as a lecturer in mathematics.

  4. Mathematical Contributions • Dodgson worked in the fields of geometry, matrix algebra and mathematical logic. • Dodgson published many math books, which include: A Syllabus of Plane Algebraical Geometry (1860), The Formulae of Plane Trigonometry (1861), and Examples in Arithmetic (1874). • He also wrote a popular mathematics book known as the “Pillow Problems”- was a workbook and people would have to think about the problems as they were sleeping. • Dodgson developed new ideas in the study of elections and committees. • Charles Dodgson published pamphlets on voting theory.

  5. Equations and Examples • These are examples from the “Pillow Problems”: • Prove to be the sum of 2 different squares, multiplied by the sum of 2 different squares, gives the sum of squares in 2 different ways (x^2+y^2)(u^2+v^2)=(xu ± yv)^2+(xu ± yv)^2. • If a, b be to two numbers prime to each, a value may be found for n which all make (a-1) a multiple of b. • If an infinite number of rods be broken: find the chance that at least one of them is broken in the middle.

  6. How Dodgson’s accomplishments are used today in the real world? • In the world of today Dodgson’s contributions in the field of voting theory are used by people who study elections. • Even though Dodgson wrote a lot of books about elections, his most important ones are “Parliamentary Elections” and “The Principles of Parliamentary Representation.” • The principles in these books are used in Europe and other places that have parliamentary systems of government.

  7. Was Charles Dodgson a great mathematician or is he overrated? • I believe that Charles Dodgson was a great mathematician because he made a lot of contributions of mathematics and politics. Dodgson was not only a mathematician but he was a photographer and novelist, which I think is pretty awesome. He created a whole book of problems that I haven’t learned to solve yet.

  8. Trivia • Name another mathematician that lives in Cheshire, England. • Alan Turing was an English mathematician and computer scientist.
