Numerical Linear Algebra By: Tiffany McKnight Robert Chirwa Alice Lin
History of Linear Algebra Babylon ~1900 BC Had an advanced mathematical system Base 60 Developed tables to calculate formulas Simple Linear equations a x = b
History continued Father of Linear algebra Hermann Grassmann Showed how to apply vectors to important applications Vector spaces Forces (Physics)
Hermann Grassman
Grassmann’s Life Born in 1809 Died in 1877 Studied 3 yrs in berlin Never formally studied Mathematics School teacher
Grassmann’s Life Wrote Ausdehnunglsehre = Theory of Extension Drew the attention of Mathematicians from around the world 1842, 1860 Theory of Tides Textbooks Translations for Encyclopedia Brittanica
Hermann Grassmann Proved integer’s properties Proved Primary Decomposition Theorem Took a century to for his works to be recognized Had work stolen by Cauchy
Johann Carl Friedrich Gauss
Johann Gauss’s Life Born 1777 Died 1855 Extremely good at Mathematics since an early age Extensive Schooling Many discoveries by the age of 19
Johann Gauss’s Life Became interested in Astronomy Wanted to work on projects that were beneficial Created Gaussian Elimination around 1800 Created Gaussian Distribution Curve
Arthur Cayley
Arthur Cayley’s Life Born 1821 Died 1895 Gifted at Mathematics at an early age Became a Lawyer Finally got an University post
Arthur Cayley’s Life Developed Theory of Algebraic Invariance Applied to the study of Space-Time Continuem Worked on Matrices foundation for quantum mechanics Suggested Special Types of Geometry
Other Algorithms Cholesky Factorization/Decomposition
