**MSCS Colloquium – Writing Numbers as the Sum of Factorials
**Suzanne Doree, Professor of Mathematics Augsburg College

In standard decimal notation, we write each integer as the linear combination of powers of 10. In binary, we use powers of 2. What if we used factorials instead of exponentials? How can we express each integer as the sum of factorials in a minimal way? This talk will explore the factorial representation of integers, including historical connections to permutations, a fast algorithm for conversion, and the secret of the “third proof by mathematical induction.” Next we’ll extend this representation to rational and then real numbers, ending with some remaining open questions.

**MSCS Colloquium – ***A Universal Taylor Series
*

You perhaps learned in Calc II that the Taylor polynomials of a function can do a very good job of approximating the original function. For example, the Taylor polynomials of y = sin x are quite well-behaved.

In this talk, we will discuss the existence of a function whose Taylor polynomials behave in the worst possible way – its Taylor polynomials can approximate any continuous function whose graph passes through the origin! In other words, the Taylor series of such a function is as divergent as imaginable; its partial sums “travel everywhere.” Such a badly behaved Taylor series is called a universal Taylor series.

Time permitting, we will also discuss a function whose successive derivatives behave just as wildly, some new research on what such a function can look like, and how you can get involved in this research.

*Robert Roy, Ph.D.| Lead Toxicology Specialist

3M Medical Department

RNS 150 7:00 PM

This presentation will focus on various aspects of industrial/occupational toxicology including: an introduction to some of the basic, although very important, principles of toxicology, various pathways to a career in toxicology (including those in the industrial, governmental and academic fields), an general overview of what toxicologists do/are involved with and where they work, and will finish with a discussion of some currently “very active” areas of toxicology. There will also be time for questions and discussion.
