Teaching this semester

MATH 1600. Differential Calculus

Mary Lou Zeeman
Functions, including the trigonometric, exponential, and logarithmic functions; the derivative and the rules for differentiation; the anti-derivative; applications of the derivative and the anti-derivative. Four to five hours of class meetings and computer laboratory sessions per week, on average. Open to students who have taken at least three years of mathematics in secondary school.

MATH 2208. Ordinary Differential Equations

Mary Lou Zeeman
A study of some of the ordinary differential equations that model a variety of systems in the physical, natural and social sciences. Classical methods for solving differential equations with an emphasis on modern, qualitative techniques for studying the behavior of solutions to differential equations. Applications to the analysis of a broad set of topics, including population dynamics, oscillators and economic markets. Computer software is used as an important tool, but no prior programming background is assumed.

Sir Christopher Zeeman turns 90Sir Christopher Zeeman turns 90. Send a Birthday Message

Sir Christopher Zeeman Archive celebrates two landmark birthdays. To mark the occasion of his 90th birthday in the year of the Society’s 150th Anniversary, the Zeeman family are producing an online archive of Sir Christopher’s lifetime work.  The Society is delighted to host an archive on one of its Past Presidents. The archive will be launched in March 2015.

Help celebrate Christopher Zeeman’s 90th birthday! The family invites you to send in your birthday greetings and well wishes, plus any personal stories and photos from time you spent with Christopher. These will be collated into a special one-off celebratory book for his birthday. It will be presented as a surprise to Sir Christopher and Lady Rosemary at the launch of the London Mathematical Society online archive of his work in March 2015, as part of the LMS 150th anniversary celebrations.
