George Cobb, Ph.D. Markov Chain Monte Carlo and the Integral:  A 2500-year Drama in Three Acts

More than any of us would like to admit, what we understand – more accurately, what we assume that we understand -- is both powered and narrowed by what we are able to compute.  Over the last 2500 years, as our capacity to compute has grown, so has our capacity to use what we can compute as a path to the concepts we rely on for understanding the world we live in.  For my argument, I rely on the history of the concept of the integral, which I take loosely to mean “how to add up a very large number of very small numbers.”

I plan to address my premise historically via the standard academic cliché of compare/contrast based on (a) chronology, (b) big questions, (c) available technology, and (d) mathematical theory.  In my planned talk I oversimplify shamelessly, reducing the stories supporting my premise to three acts:

Act I:   Classical Greece (around 350 BCE):  motion and area; infinite sums and adding

 a geometric series.

Act II:   Enlightenment (2nd half of the 1600s, after two millennia of dormancy):             

total net change and area; the Fundamental Theorem of Calculus tells how to

convert instantaneous rate of change to total net change, allowing Newton to

explain the universe.

Act III:  Computer age (Two-and-a-half centuries later, starting around 1950):  the

Ergodic Theorem tells how to compute the integrals that defeat calculus. Applications include robotics, computer vision, molecular biology, and the ecology of species distribution.  Don’t be put off by “Fundamental Theorem of Calculus” and “Ergodic Theorem”.                                        If the phrase “add up a very large number of very small numbers” makes sense, you have all the mathematical background you need for my talk.

Joint CS/Math/Stat Club Lunch

Wednesday September 21, 2016, 12:15-1pm, Clapp 407 : Turan's Problem

What is the maximum number of edges in a graph on n vertices without triangles? Mantel's answer in 1907 that at most half of the edges can be present started a new field: extremal combinatorics. More generally, what is the maximum number of edges in a n-vertex graph that does not contain any subgraph isomorphic to H? What about if you consider hypergraphs instead of graphs? We will explore different strategies to attack such problems, calling upon combinatorics, integer programming, semidefinite programming and flag algebras. We will conclude with some recent work where we embed the flag algebra techniques in more standard methods.  This is joint work with James Saunderson, Mohit Singh and Rekha Thomas.   


Wednesday, September 14, 2016, 12:15 - 1:00 pm Clapp 416: Welcome Meeting

This first meeting will be organizational.  You will meet math/stat faculty, hear about the student groups working on various types of problems, find out what kinds of activities the club usually has and brainstorm about what it might have.  We'll let you know what is already on the agenda, but bring lots of good new ideas with you.

How data drives internet marketing success
Have you ever seen a Facebook advertisement for something you recently searched on Amazon? Have you ever Googled 'food delivery', for example, and wondered how the websites from your search are ranked?
In this talk I will discuss the quantitative approach of problem-solving and decision-making in modern online marketing and the importance of data analytics in a startup world. I will also share my post MHC experience and am happy to answer questions about the mathematics curriculum, the dual-degree program, job hunting and/or interview preparation.

How do I know your knot is not my knot?
Take a piece of string, tie your favorite knot in it, then glue the ends together. Congratulations, you've made a mathematical knot! Now suppose your friend does the same thing. You both might have what now looks like a tangled pile of string, but it's possible that both of you really made the same knot. In this talk we will discuss some tools, known as knot invariants, that can help us decide if two knots are different. We'll see that we might be able to tell two knots apart simply by coloring them, or by keeping track of what happens when we "unknot" them carefully.

FRIDAY, MARCH 25, 3:00-4:00 pm, 305 Kendade--Speaker: Adelyn Yeoh '15, MSCF Student at Carnegie Mellon Tepper School of Business

An introduction to mathematical tools used in quantitative finance
Interested in a career in quantitative finance or pursuing graduate studies in the field?  Wonder what mathematical tools are used to develop financial instruments?  This talk will show how tools from probability, calculus and linear algebra directly relate to the models and tools used in quantitative finance.  In particular, we will use the popular Black-Scholes model which is commonly used in estimating the price of derivative instruments called options as a motivating example.  We will also discuss common interview questions and the required preparation to either pursue graduate studies or a career in the field.  Finally, we will round of with a discussion of the growing need for women to enter the industry.

Analyzing large-scale data: Taxi tipping behavior in New York City
Statisticians are increasingly tasked with providing insights from large streaming data sources, which can quickly grow to be terabytes or petabytes in size. In this talk, I explore novel approaches for applying classical and emerging techniques to large-scale datasets. The utility and insights garnered from these methods are shown through an application to an event based dataset provided by the New York City Taxi and Limousine Commission. I have joined these observations, which detail every registered taxicab trip from 2009 to the present, with external sources such as weather conditions and demographics. I then use the aforementioned techniques to explore factors associated with taxi demand and the tipping behavior of riders. My focus is on developing novel techniques to facilitate interactive exploratory data analysis and to construct interpretable models at scale.

TUESDAY, March 1, 12:15-1:00 pm, 416 Clapp--Speaker: Eva Goedhart, Visiting Assistant Professor, Smith College

Is Data Science Right for you?  Five Principles for thinking about it

I currently think of myself as a data scientist, but I've spent my life changing my mind: my childhood ambitions, in succession, were to be a herpetologist, a center for the Green Bay Packers, a surgeon, a chemist, and, by the end of my senior year in high school, aspiring ever upward, a mathematician.

In my talk I'll do my best to help you think about whether data science is a subject you might want to think about thinking about: What do data scientists - dare I say it - actually think about? What are the opportunities in data science? What do you need to know? How can you decide whether data science might be right for you? I'll offer five ways to think about thinking about it.

Monday, February 8, 12:15-1:00 pm, 416 Clapp--Speaker: Christina Hamlet

Mathematical and computational modeling of a swimming lamprey from activation to locomotion

Lampreys are vertebrates which serve as model organisms for both neurophysiology and locomotion studies, owing to certain properties of their nervous system and their manner of swimming. By modeling lamprey swimming we can gain insight into how a flexible body can swim rapidly and efficiently through a fluid as well as into physical constraints on biological functions. I will discuss the construction of a computational lamprey which combines mathematical models of neural activation, muscle mechanics, fluid dynamics, and sensory feedback. I will present how the different models are coordinated and then numerically solved to produce simulations of swimming behavior. I will show that we can then examine how properties of muscles, neural activation and sensory feedback can affect how fast and how efficiently the virtual organism swims. I will also illustrate how each model may be isolated to study the properties of individual systems, allowing us to compare the independent performance of each model to its performance when coordinating with other systems.

Friday, February 5, 12:15-1:00 pm, 416 Clapp--Speaker: Daniel Stroembom

Mathematical modeling of collective motion in animal groups

Animal groups, for example schools of fish and flocks of birds, often exhibit highly coordinated complex dynamics while moving together. How is this accomplished when each individual only interact directly with its immediate neighbors and no identifiable leaders, or coordinators, exist? Over the past few decades the use of so called self-propelled particle models have significantly improved our understanding of how coordinated collective motion arises from local interactions between the individuals in a group. For example, we can now generate a variety of artificial flocks that share both qualitative and quantitative features with real world flocks by specifying sets of biologically plausible individual interaction rules, e.g. attraction and repulsion. However, there are many unresolved issues that limit the utility of these models, both as theoretical devices for studying collective motion in general and in modeling collective motion in specific species. In this talk a brief introduction to collective motion in animal groups and self-propelled particle models will be provided, and current modeling challenges and ongoing research efforts to meet them described.

Wednesday, February 3, 12:15-1:00 pm, 416 Clapp--Speaker: Timothy Chumley

Random billiards with microstructure

Billiard models in mathematics consider the motion of a point particle traveling in a spatial domain, called the table, with piecewise smooth boundary. In this talk we consider a generalization of such models, called random billiards, where the usual law of specular reflection (equal angle of incidence and reflection) is replaced by a random reflection law. Of particular interest will be random billiard models whose random reflection law is constructed in a way that models a microscopic structure, such as roughness, on the boundary of the table. The resulting models are examples of Markov chains and our main focus will be on how geometric parameters of the microscopic boundary structure influence the dynamics of these Markov chains. We give a flavor for the probabilistic limit theorems of interest, such as ergodic theorems and central limit theorems, and the tools used, from linear algebra and analysis to numerical simulation, through a few examples.

The Teetotaler's Tour: using geometry to create chaos out of simple motion

A geodesic flow is an object that keeps track of all the "straight line" trajectories on a surface. Despite their innocuous sound, geodesic flows can exhibit a great variety of interesting dynamical properties-including chaos!-depending on the geometry of the surface. In this talk, I will describe mathematical machinery for studying the relationship between dynamics and geometry, show some pictures of surfaces with fascinating dynamical properties, and state some interesting open problems.

Possible Quantifications of Resilience

Quantifying resilience has become an important question in natural sciences such as ecology, biology, and climate science.  However the definition of resilience is ambiguous and there is room for multiple mathematical interpretations in the context of the question resilience of what to what?  We'll look at a couple of options for quantifications of resilience and consider the case of repeated state space perturbations to a system, as well as ideas for further inquiry into what it means for a system to be resilient.

Monday, January 25, 12:15-1:00 pm, 416 Clapp--Speaker: Jose Gonzalez

A tale of invariants

An invariant is a property of a class of mathematical objects that remains unchanged under a certain type of transformation.  Finding the correct invariant is frequently all that is needed to explain an otherwise perplexing mathematical situation.  We will consider some neat examples of both general and specific to current research projects with undergraduate students.

Friday, January 22, 12:15-1:00 pm, 416 Clapp--Speaker: Jesse Gell-Redman

Invariants of Singular Spaces

One of the fundamental distinctions in mathematics is that between the local and global invariants of a space.  A global invariant is a property of a shape that depends on how the space looks in its entirety, i.e. from far away. Examples include the number of sides a polygon has or the number of holes in a surface. (Does the surface look like a basketball, so zero holes, or like a doughnut, so one hold?) Local invariants come from the actual geometry itself, the main example being a numerical measure, called the Gauss curvature, of how much a space is curved at a given point.

As I will explain, local and global invariants of spaces are related in a profound way. Although this relationship has been known for a long time, it is not well-elaborated in the context of singular spaces, i.e. shapes like cones or horns which have a point or points that are not smooth. That would be fine, were it not the case that some of the most interesting geometries that arise in mathematics and physics are singular! I will illustrate the latter statement with simple examples and explain how progress can be made understanding invariants of these spaces.

From Circle Rotations to Interval Exchange Transformations

Dynamical systems is the study of the long term behavior of systems.  Today we will begin by learning about rotations of the circle.  These maps are very intuitive and we'll all be experts in no time.  Then, we'll move on to interval exchange transformations, which are a natural generalization of circle rotations.  We'll discuss some cool properties of these maps, and I'll leave you with an open question.

Causal Inference in Statistics: Comparing apples to apples in the absence of randomization

When units in a study are not randomized to treatment groups, they are not directly comparable.  We will discuss the basic ideas of causal inference in Statistics and one of the most fundamental adjustment methods to ensure comparability across units - propensity score matching.  The ideas will be presented through the lens of a case study to compare complication rates in routine angioplasty procedures resulting from differing surgical techniques.

The 2-dimensional harmonic oscillator problem and linear flows on the torus

In this talk we'll see how to solve the 2-dimensional harmonic oscillator problem by solving the differential equations (like you'd learn to do in Math 333).  But then we'll take it a step further and look at the problem from a dynamical systems perspective!  We'll take a look at the topology of invariant sets of solutions (tori!) in the phase space and what happens to the solutions on these sets for different harmonic frequencies, and eventually figure out how to get the coolest drawings on a real life 2-dimensional harmonic oscillator machine.

Big Data Literature Analytics for Disease Dynamics

Text summarization is important in guiding analysts in the so-called problem of 'storytelling'.  Storytelling entails quantifying complex relationships among entities within text for prediction of interesting stories or paths.  Here we present an automated framework of text summarization and visualization.  We focus on capturing and displaying entity relationships to aid in storytelling.  We break our algorithm into the processes of Reading, Assembling, and Interpreting entity-entity interactions.  This talk focuses on interpretation where we discuss how network science captures topological differences between disease topic areas.  We use case studies in biomedical (disease) literature to show how our approach provides summarization of chemical treatments, tracks the evolution of literature, and can be used to find latent links between research areas.  Finally, we adapt Stirling's (2007) framework for quantifying diversity and create a diversity heuristic to be used in science and technology policy for comparing research areas.

Wednesday, October 21, 12:15-1:00 pm, 416 Clapp--Speaker: Andrew Bray

Branch, Bound, and Kill: a family-friendly algorithm for statistical inference

Of central importance to statistical modeling is the likelihood function: the function that expresses all of information held in a data set in the context of a particular statistical model.  Despite its centrality to the statistical process, the likelihood is often frustratingly difficult to deal with analytically.  Of particular interest are the regions where these functions are high, and to find them statisticians often resort to general optimization algorithms that may fail to find the global optimum.  In this seminar we'll discuss a branch and bound style algorithm that evaluates the function to an arbitrary degree of precision within a given region of the parameter space, ensuring that no optima are excluded.


Wednesday, October 14, 12:15-1:00 pm, 416 Clapp--Math in the Movies and "The Great Math Mystery: Is Math Invented by Humans, or is it the language of the Universe?"

After a brief overview of the Math in the Movies websites, we will watch the recent (April 2015) NOVA Video on a mathematical mystery tour--a provocative exploration of math's astonishing power across the centuries.  We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral in the center of a sunflower.  Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars.  Astrophysicist and write Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond.  It all leads to the ultimate riddle: "Is math a human invention or the discovery of the language of the universe?"

The Power of a Ranking: Quantifying the Effects of Rankings on Online Consumer Search and Choice

In this talk I will tell you about my journey from a Math and Economics major at Mount Holyoke College to a PhD student in Economics at the University of Chicago. For my thesis, I study how consumers’ choices are influenced by the order in which products are presented to them. I focus on an experiment done at Expedia where consumers saw hotels ranked in a random order instead of Expedia’s proprietary ranking. This experiment is exciting because it allows me to identify the causal effect of a ranking on purchases, which was previously not possible, as well as study how consumers’ online search is influenced by the ranking they observe. As we advance in an era of information abundance that has to be summarized in order to be useful, understanding how rankings affect choices is paramount. I will focus on how I am using math to study consumer behavior, as well as venture back to my MOHO days and discuss relevant coursework and preparation for those of you who are curious about graduate school.

Segmenting salient objects: How does statistics bring African safari closer to cancer tumor?

Segmentation is a difficult problem in computer vision. Numerous methods have been developed over the last few decades to tackle this problem. However, there are only a limited number of available methods specially customized for tissue images, in particular ones of biopsied tumors. The biopsied tumors are crucial to treatment decisions for cancer patients. A key component of biopsied tissue analysis is to identify diagnostically relevant architectural elements in a tissue. Despite the significance of this task, most of the currently available segmentation methods are not sufficiently robust and scalable due to their ulitization of highly engineered features and requirements of extensive training data. Recent developments in segmentation of natural images (e.g. African safari) show that statistical representation has the potential to overcome the aforementioned challenges. I will demonstrate a new segmentation approach inspired by state-of-the-art computer vision methods using images of breast tissues.

Statistical programming-- past, present, and future
While statistics has been practiced for centuries, and computer-aided statistics for decades, we are still learning what makes it easy to do and understand statistics. Statistical computing tools have improved since the early days, but there are still features dreamed of in the 1970s that remain unimplemented, and many computational programs simply attempt to emulate what was done with pencil and paper. However, computers offer the possibility to go beyond just speeding up processes that could be done by hand, and data have changed since the time when many statistical packages were written. So, it is clear there is a need for new computational tools.
Furthermore, there is a gap between the tools we use to do statistics and those we use to learn and teach statistics. Often, there is no bridge to span that gap, which leaves users to struggle to make the connection. My research explores the qualities of a statistical programming tool that would support a user "from cradle to grave," taking them through the entire learning-to-doing trajectory. I will present my theory and an experimental prototype that shows some of the features I envision.

Translating Math into a Career
Navigating the roadmap from education to career is challenging in any discipline. As a Mathematics or Statistics major in particular, the opportunities are endless, but this does not make it any easier. My undergraduate education in Mathematics prepared me for a strong career in a way I had not understood until recently. I will be discussing my journey that led me to work in a biostatistics lab here at MHC, as well as some of the reasons I find biostatistical research to be interesting. I will also give a brief overview and example of the kind of data and challenges we deal with everyday that make positions like mine invaluable.

A brief discussion of interdisciplinary studies combining mathematical principles with life sciences

Biostatistics and bioinformatics are two overlapping fields of study that combine elements of mathematics, statistics, biology, public health and computer science.  Both involve building, applying and evaluating useful mathematical models, within the context of life and health science research. In this talk, I will discuss how I came to pursue degrees in both areas. I will introduce topics in genetics that illustrate the utility of a fundamental understanding of mathematics and statistics. Lastly, I will summarize some of the highlights of my own collaborative research, which seeks draw inference for association between genetic variation and the expression of specific traits.

Geometry and the complexity of computation

Algebraic geometers study curves, surfaces, and higher dimensional objects that are defined implicitly by systems of polynomial equations.  Manipulating polynomial equations on a computer can reveal interesting geometric properties of their solution sets. There are examples showing that such computations can be very costly in general.  However, in nice geometric situations, computations are often quite manageable. I will discuss joint work with Aldo Conca treating a special case of this phenomenon.

Using Randomization to Understand Neural Networks

The brain is comprised of millions of neurons, connected in particular patterns in order to send electrical impulses and messages between one another. These neurons and connections are often visualized as graphs comprised of points and lines, called vertices and edges. On the graph, vertices represent individual neurons and edges represent the connections between them.

While sleeping or resting, the hippocampus of the brain sends electrical impulses in a Sharp Wave Ripple (SWR) pattern which helps the brain form memories. Given a specific set of data which represents a neural network of the hippocampus of a rat brain, my research group used computer simulations to understand which particular aspects of the structure of the neural network were vital to have a functioning hippocampus, as determined by the presence of SWR. This was done using randomization processes on an adjacency matrix of the neural network in order to rule out one at a time which aspects of the network are not necessary to produce SWR.

Systems Simulation Modeling for Public Health Applications

Infectious diseases such as HIV, TB, malaria, and Ebola disproportionately affect certain populations. Though the how-tos of prevention are known, their implementations are challenging because of the complicated interactions between disease, socio-economics, and behavior. A holistic approach to disease prevention often includes interventions at the individual-level, such as testing programs to diagnose and treat infected persons, interventions at the population-level, such as awareness programs, and interventions at the systemic-level, such as timely updates to guidelines and policies. Interventions may also include continuing care at various stages of disease progression to minimize disease burden. Several of these interventions differ by population groups based on need.

Given these complicated interactions, techniques that can model the dynamics of these interactions, such as systems simulation models, are used to evaluate intervention scenarios so the limited resources can be allocated efficiently. Analyses of short- and long- term impacts and costs of alternative scenarios of combination intervention programs could inform the development of strategies for disease prevention. In this talk I will discuss two types of systems simulation modeling techniques, compartmental and agent-based, for application to public health decision making.

Euclidean proofs of the infinitude of primes in arithmetic progressions

Euclid's proof that there are infinitely many prime numbers is known for the simple yet elegant way it argues this classic result.  In 1837 Dirichlet proved the following generalization: if a and n are integers whose greatest common factor is 1 then there are infinitely many primes of the form a + nk for some integer k.  For example, if a = 1 and n = 4 then this means there are infinitely many primes of the form 1 + 4k where k is some integer.  That is, there are infinitely many primes like 5 = 1 + 4, 13 = 1 + 4(3), 17 = 1 + 4(4) and so on.  However, in contrast to Euclid's proof that there are infinitely many primes, Dirichlet's argument uses some deep results of analytic number theory.  In the course of this talk, we will give Euclid's classic proof, explain what we mean by a Euclidean proof of Dirichlet's theorem and then endeavor to answer the question: is it possible to provide a simple proof along the lines of Euclid's argument for Dirichlet's theorem?

Statistical Analysis of Real-World Networks

Network data representing complex phenomena in fields such as biology, physics, economics, finance and education is abundant today. Social online networks (e.g. Facebook, Twitter), brain networks, gene networks, financial networks, friendship networks of teachers in schools, etc. are some of the examples of such real-world networks. Researchers hope to understand underlying complex phenomena that form such networks in these fields by analyzing observed network data. A network consists of fixed nodes (e.g. social online users) and dependent edges (e.g. friendship relations). Many real-world networks are noisy and very large. Modeling stochasticity in such highly dependent complex structures poses challenges in existing statistical approach and is computationally harder. Most of the recent works in statistics to analyze networks has been on this front. In this talk, I will delve into the need to build consistent and interpretable statistical models to analyze real-world networks in a systematic and computationally feasible manner. I will motivate the talk by giving examples of networks from different domains, as well as the associated questions researchers in these domains attempt to answer. Next, I will give a general overview of the existing methods for network analysis. In particular, I will discuss ongoing work in the Hierachical Network Methods (HNM) research group in the Statistics Department at Carnegie Mellon University.

How do we get to the line at infinity?  An introduction to projective space.
In high school geometry we learn that any two lines in the plane must intersect unless they are parallel.  We may also observe that the sides of a long, straight road seem to meet at the horizon.  This suggests that we might be able to augment the plane with a line "at infinity," and that parallel lines will intersect at a point on this new line.  In this talk we will make these ideas rigorous by constructing the projective plane.

Perspective in Two Dimensions for Computer Graphics

Holding in mind a 2D projection of a 3D scene is easy; holding in mind the 3D scene is hard. According to recent research in perception the human brain deals more easily with 2D representations than with 3D ones. When perspective was re-invented in the Renaissance artists quickly discovered how to construct accurate perspective without having to work in 3D. Doing so they were able easily to combine perspective with composition, which is dominantly 2D. From this point of view, modern computer graphics seems gratuitously difficult in forcing its users to develop full 3D models.

The seminal construction in Renaissance artists' perspective is the tiled floor, the many constructions of which I will explain in detail. Having reduced it to 2D perspective geometry, I will show how other useful constructions can be similarly reduced, including the double projection required for accurate shadows. Artists did these computations geometrically, drawing lines to find their intersections. Using my formalism to reduce geometry to algebra, computers can reproduce the 2D perspective calculations used by artists.

If a tree grows in a forest, will a statistician count it?  An introduction to survey sampling

Surveys are fairly common in our society and allow one to make inferences about a population of interest based on sample. The sample data, collected using a complex sampling design, can often be supplemented with additional data.  In this talk I will discuss how to estimate a population quantity in the presence of both survey and additional data.  In particular, I will present an estimator I developed -- the LASSO Survey Regression Estimator -- and I will address how this estimator compares to other commonly used survey estimators when estimating tree canopy cover for a region in Utah. 

Monday, January 27, 12:15-1:00 pm, 416 Clapp -- Speaker: Andrea Foulkes

Statistical deception and the era of "big data"

The familiar phrase "Lies, damn lies and statistics" takes on new meaning in the era of "big data".  In this Math/Stat club talk, we will begin by exploring various ways in which statistics and statistical graphics have been used to persuade and, at times, deceive us. Focus will be on the thematic use of several important statistical concepts, ranging from misrepresentation of a mean to taking advantage of the presence of selection bias. We will then consider how big data applications present an entirely new opportunity to use these old tricks, as well as a few new ones. Students (and faculty) will learn to have a more discerning eye, as well as learn about why understanding and applying elementary statistical concepts is so important in the big data arena.

"Enabling Secure Computing through Fully Homomorphic Encryption"

Come join us for an very interesting cross-disciplinary talk by Kurt Rohloff of BBN Technologies. 

One of the major breakthroughs of theoretical computer science in the 20th century was the formalization and development of mathematically secure encryption technologies.  These breakthroughs have enabled people to securely share information over the Internet without prior interactions.  In this talk we'll provide an introduction to prevalent encryption technologies such as one-time pads, AES-based symmetric key encryption and RSA-based public key encryption technologies.  We'll particularly focus on practical trade-offs associated with building and using these technologies.  Building upon this prior work, we will also discuss the first major breakthrough of computer science in the 21st century - the demonstration of public-key Fully Homomorphic Encryption (FHE). FHE allows sensitive data to be encrypted such that arbitrary programs can be securely run over the encrypted data where the output, when decrypted, is equivalent to the result of running the original algorithm on the unencrypted data.  FHE is an area of high ongoing interest from both theoretical and practical perspectives.

Events for Spring 2013


The Problem Solving Seminar is an off-shoot of the Math/Stat club.  Students who intend to take the Putnam along with others interested in improving their problem-solving  abilities meet weekly on Friday for lunch noon to 1:00 in Clapp 416 (in the fall semester) with a faculty member to work on problems.  The seminar is not for credit, it is an extra-curricular activity.  Read this article about our problem solving group Some Truly Impressive Figures, May 2, 2011.

This year the club will hold its first meeting on Friday, September 28, problems get sent out on Sundays for group members to look over. We alternate weeks between solving problems one week and practicing our presentations the next week. On the first Saturday in December members from the Problem Solving Seminar take the Putnam exam.

Are you interested in learning to use mathematical methods to solve real world problems? The Mathematical Modeling Club meets weekly to discuss modeling strategies and work together on problems. Members of the Mathematical Modeling Club will elect a 3-person team to represent Mount Holyoke College in an international mathematical modeling contest that takes place in February. You do not need to be a mathematics or statistics major. Being able to think creatively about how to solve real problems is the most important thing, and the group benefits from having a variety of perspectives. People from other disciplines are welcome!

If you are planning to take the GRE Subject Test in Mathematics this fall (October or November), you should be working problems in as many sample tests as you can find.  You should also be giving yourself timed practice tests, since there is no substitute for that experience.  If you have questions about any aspect of this exam, whether about particular problems or particular topics, be sure to get those answered.

You're more than welcome to join the Mount Holyoke Actuarial Club if you're interested in becoming an actuary and want to learn a great deal about the insurance industry!

The Actuarial Club at Mount Holyoke College aims to help its members become strong actuarial candidates, to provide resources necessary for them to prepare for an actuarial career, and also to build a professional network with our wonderful alumnae actuaries.
