# Mathematics

Albright’s mathematics faculty are committed to giving students the tools and knowledge needed to achieve their goals. Faculty are available for extra help during office hours or individual appointments. They employ the latest technology—such as various iPad applications, Matlab, Excel with Visual Basic, Maple, Mathematica, and TI-89 and TI-200 graphing calculators—combined with traditional and experiential learning techniques to prepare students for success after graduation. Small class sizes benefit students from their first calculus course all the way through Abstract Algebra and Real Analysis. The most advanced classes offer even more attention, which helps students to understand complex subjects.

**Mathematics Mission Statement:**

Mathematics offers an important way of viewing, analyzing and interpreting the world. It allows us to observe patterns, develop conjectures and make predictions. We strive to nurture a mathematical point of view in our students at all levels whether they are pursuing a liberal arts education in the humanities, in need of mathematical skills to complement other fields of study or wish to study mathematics as a core discipline.

We also aim to provide a thorough undergraduate training in mathematics for those students who wish to pursue graduate study in mathematics, teach mathematics in the secondary school systems, or work in various fields of business and industry.

The mathematics department will attain these goals by:

- Providing an up-to-date curriculum that is both broad in diversity of subject matter and rigorous in content.
- Expand students’ mathematical reasoning, problem solving and communication abilities.
- Promote connections with other disciplines through the co-concentration program.
- Develop students’ use and appreciation of technologies relevant to the study of mathematics.
- Provide a curriculum of general education mathematics courses with substantive skill development in quantitative and abstract reasoning.

Albright Mathematics students learn to:

- become confident in their ability to do mathematics and statistics,
- become mathematical problem solvers,
- learn to communicate, reason, and function mathematically in a mathematical, statistical, and technological learning community,
- apply both qualitative and quantitative methods,
- demonstrate oral communication skills,
- demonstrate written mathematical communication skills.

### Mathematics Colloquium

**November 2017
Samantha Pezzimenti & Hannah Schwartz – Bryn Mawr College
“Introduction to Knot Theory”**

Abstract: Since the 19

^{th}century, mathematicians have studied knotted loops in space. Despite the concept of a knot being well-understood in artwork and culture, knot theory remains a rich field of topology with many unanswered questions. We will introduce some foundational ideas such as isotopy, invariants, and Seifert surfaces, in order to address some underlying questions in the field: When are two knots the same? When are they different? How can we distinguish them? This talk will be informal, interactive, and accessible.

**April 2017
Dr. Michael A. Jones – Mathematical Reviews
“A Voting Theory Approach to Golf Scoring”**

Abstract: The Professional Golfer’s Association (PGA) is the only professional sports league in the U.S. that changes the method of scoring depending on the event. Even without including match play or team play, PGA tournaments can be scored under stroke play or the modifed Stableford scoring system; these two methods of scoring are equivalent to using voting vectors to tally an election. This equivalence is discussed and data from the 2004 Masters and International Tournaments are used to examine the effect of changing the scoring method on the results of the tournament.With as few as 3 candidates, elementary linear algebra and convexity can be used to show that changing how votes are tallied by a voting vector can result in up to 7 different election outcomes (ranking all 3 candidates and including ties) even if all of the voters do not change the way they vote! Sometimes, regardless of the voting vector the same outcome would have occurred, as in the 1992 US Presidential election. I relate this to the question: Can we design a scoring vector to defeat Tiger Woods? And answer it, retrospectively, for his record-breaking 1997 Masters performance.

**October 2016
Dr. Eva Goedhart – Lebanon Valley College
“Minding My p’s and q’s: Using Continued Fractions to Solve Diophantine Equations”**

Abstract: After a friendly introduction to continued fractions and Diophantine equations, we show how continued fractions can be used to solve a family of Diophantine equations.

**March 2016
Dr. Hugh Denoncourt – CUNY
“Mathematical Oddities and Their Meanings”**

Abstract: Many familiar operations have a simple interpretation. For example, Multiplication is repeated addition and exponentiation is repeated multiplication. Yet, even as early as high school algebra, we find ourselves raising numbers to negative and fractional values and somehow making sense of it. Similarly, we understand what it means to sum a collection of finite numbers. Yet, in calculus, we are tasked with making sense of assigning values to infinite sums. Is this expansion of familiar operations into unfamiliar territories just a game that mathematicians play? If so, are there rules or is it all pure invention? In this talk, we explore these questions through a tour of such oddities as complex numbers and divergent sums. We explore modern ideas that may help remove some of the mystery surrounding these objects.

**November 2015
Dr. Tom Concannon – King’s College
“Understanding Gravity: Relativity, Black Holes, and Beyond”**

Abstract: Newton originally conceived of a universal gravitational law in a explicit mathematical form, stating that the gravitational force is an attractive force between two massive objects proportional to the product of their masses and inversely proportional to the square of the distance between them. But Einstein improved on his definition and, in the process, unified space and time into one entity, space-time. This powerful formulation gave birth to radical new ideas about how we perceive motion in space and our passage through time as well as gave validity to the idea of black holes, strongly gravitationally bound systems from which not even light, the fastest thing in the universe, can escape. In this talk, we’ll explore the foundations of gravity, from Newton to Einstein and beyond, from its cosmological implications to its quantum ramifications via string theory, a possible unified description of all known physical laws.

**April 2015
Dr. Stanley Ryan Huddy – Fairleigh Dickinson University
“An Introduction to Chaos Theory”**

Abstract: If a butterfly flaps its wings in Brazil does this set off a tornado in Texas? Why are weather reports often incorrect? Join me as we answer these questions and more through a visually interactive introduction to chaos theory.

**November 2014
Dr. Kathleen Ryan – DeSales University
“Non-Diplomatic Degrees!”**

Abstract: A

**graph**is a set of vertices together with a set of edges between some pairs of vertices. We say that the

**degree**of a vertex in a graph G is the number of edges incident to the vertex. If we create a list of integers consisting of the degree of each vertex in G, then the resulting list of integers is called the

**degree sequence**of G. Given a sequence of integers d=(d

_{1},d

_{2},…,d

_{n}), we explore the answer to the following question: When does there exist some graph whose degree sequence is d? We then explore a generalized version of this question for edge-colored graphs within certain graph families.
