1
The Putnam Exam During Year Zero USMA-Harvard Math Competition of 1933 Presented By: CPT Michelle Isenhour Western Michigan University

2
Putnam Mathematical Competition Conducted by the MAA Began in 1938 and has prospered since Named after the late William Lowell Putnam 12 questions in two three-hour sessions Individual and team awards

3
The Legacy of Putnam 1921 – Putnam suggested the development of academic competition 1928 – English competition between Harvard and Yale (Harvard won) Yale and Princeton declined further competitions in English Cambridge declined competition in Economics

4
The Trouncing… November 1932 – Army trounced Harvard in football 46-0 President Lowell proclaimed that Harvard could just as easily win any contest of a more academic nature

5
The Challenge… …I would very much like to test our method of teaching mathematics against that of your institution. I, frankly, think our method is superior to yours, and would like to try it out. - Major General Connor, Superintendent of the United States Military Academy in a 1932 letter to President Lowell

6
Preparations for the Competition Rules delegated to department heads –Lieutenant Colonel Harris Jones, USMA –Professor William C. Graustein, Harvard Exchanged information about curricula, pedagogy, and students

7
West Point Curricula Four semester core curriculum –Freshmen: 8 hours per week –Sophomores:4 hours per week Subjects –Algebra and Trigonometry –Solid and Analytic Geometry –Differential and Integral Calculus –Least Squares (upper 1/3 of class)

8
Harvard Curricula Freshmen –Met for 3 hours per week –Textbooks Osgood and Graustein, Plane and Analytic Geometry Osgoods Introduction to Calculus Sophomores –Under guidance of tutors –Subjects Analytic Geometry Algebra

9
Oscillation Begins… Resolved Issues –Topics examined: analytic geometry and calculus –Sophomores examined in May 1933 Unresolved Issues –West Point wanted 20-25 contestants, Harvard 10 –Home Team and Host –Length of Test

10
Continues… LTC Jones, USMA –Offered to lower the number of contestants to 15 and have his team travel to Harvard for the test on 20 May –Suggested one three-hour test claiming six-hours would convert and interesting contest into dull drudgery and kill the enthusiasm of the competition

11
Continues… Professor Graustein, Harvard –Established the number per side as 10 –No expectation that the Military Academy would bear any part of the expense –Two three-hour sessions with the second more challenging –Twice as much calculus as analytic geometry and include theoretical questions on test –Allow formula cards, logarithm tables, and Pierces Integral Tables as references –Harvard would be happy to travel to West Point

12
…and Ends LTC Jones, USMA –Agreed to two-part test and use of Pierces Integral Tables –Scoring would be that used in cross-country meets

13
Completing the Committee President of the MAA – the body which stands for collegiate mathematics in this country Professor Arnold Dresden seemed almost ordained for the job and accepted the invitation

14
Scope of the Examination (1 of 2) Plane Analytic Geometry –Distance from a point to a line –Conics – Derivation of equations in rectangular and polar coordinates –General equation of the second degree; simplification by translations and rotation of coordinate axes –Locus problems involving applications of the above Solid Analytic Geometry –Equations of straight lines and planes –Distance from point to a plane or line –Equations of spheres, cylinders, cones, surfaces of revolution –Elementary properties of quadric surfaces

15
Scope of the Examination (2 of 2) Calculus –Curve tracing –Velocity, acceleration, rates –Radius and center of curvature –Evolutes –Taylors Theorem, functions of one variable –Series – tests for convergence, expansion of functions, integration –Applications to mechanics, center of gravity, moment of inertia, radius of gyration, attraction, fluid pressure, work –Elementary differential equations, first order, linear equations with constant coefficients, orthogonal trajectories, simple equations of higher order

16
Preparations for Battle – West Point West Point Team Statement We are really series about this contest. We really mean it. Were just dyne to meet those dumb Harvard guys, and were determinant to win. We all hope to make our integral signs.

17
Preparations for Battle – West Point From March 15 – May 20 –Excused from parade 3 days a week –Excused from intramural athletics –Drilled in extra mathematics two afternoons a week

18
Preparations for Battle - Harvard Confident of Victory Took a lighter approach Met with coach about four times Assumed Harvard intellects would easily carry the day

21
Other Headlines Army meets Harvard in Mathematical Go Squads at West Point Begin Contest in Calculus and Analytic Geometry Harvard and West Point Line up on the Geometry Field

22
The Test Part I – Friday, May 19: 3 hours –11 problems: 6 analytic geometry, 2 differential calculus, 3 integral calculus –Part II – Saturday, May 20: 3 hours –11 problems: 1 logarithms, 3 analytic geometry, 6 differential calculus, 1 integral calculus Not as difficult, nor as challenging, as the first National Putnam Examination given on April 16, 1938

23
And the Winner is… Crimson Bow to West Point Mathematicians Harvard Mathematics Team Outfigured by West Pointers

24
The After Math All members of the Army team finished in the top 20 of their graduating class; seven of the ten spent over 20 years in the Army; most later became professors and obtained their Ph.D. None were mathematicians; all were engineers

25
Putnams Legacy Harvard-USMA competition was not repeated Putnams sons, George and August, consulted with George Birkhoff of Harvard to keep the dream alive Birkhoff and colleagues from the department wrote the first national examination in 1938 Set up continuing principles for the competition –Teams consist of three people –Tests are administered by the MAA –Prizes are distributed to several top teams and individuals

26
Conclusion Through the efforts of Birkhoff and many others, and the experience garnered from the Harvard-USMA Competition of 1933, the annual William Lowell Putnam Mathematics Competition came into existence in 1938 and has prospered in the 50 years since. -David C. Arney and George Rosenstein USMA-Harvard Math Competition, 2000
