### From the Ham Sandwich to the Pizza Pie:

An Introduction to Topological Combinatorics

#### Steve Simon, Mathematics Program

Given any 3 shapes in R3 (e.g., a piece of ham, a hunk of cheese, and a slice of bread), does there exist a single plane that simultaneously cuts each shape into two pieces of equal volume? Can any shape in R2 be dissected into four pieces of equal area by some pair of perpendicular lines? By exploiting hidden geometric symmetries, we will show how equipartition problems such as these can be solved using powerful techniques from the seemingly unrelated eld known as algebraic topology. For instance, the positive answer to the rst problem above { the so-called Ham Sandwich" Theorem { ultimately reduces to a very deep result of Borsuk and Ulam: for any continuous map from a sphere to a plane, there must exist a pair of antipodal points on the sphere whose images coincide. While fairly advanced mathematics is not too far away, this talk requires only a familiarity with the intermediate value theorem to be understood. All are welcome to attend!

### Protein Folding: Seeing is Deceiving

*Once you eliminate the impossible, whatever remains, no matter how improbable, **must be the truth. -Sherlock Holmes*George RoseJenkins Dept. of BiophysicsJohns Hopkins University

We challenge the time-honored conviction that proteins realize their native folds via specific favorable interactions, proposing instead that an imprint of the fold is selected primarily by elimination of unfavorable interactions. Two types of energetically disfavored interactions are considered here: steric clashes and polar groups lacking hydrogen-bond partners. Both types are largely excluded from the thermodynamic population, winnowing that population progressively as the protein becomes compact. Compaction is accompanied by the entropically favored release of solvent shells around apolar groups. Remarkably, both solvent shell release and excluding interactions are somewhat non-specific, yet together they promote highly specific chain organization. For example, exhaustive conformational enumeration of a test hexapeptide reduces 1.5x1012 conceivable conformations to the experimentally-determined dominant population in aqueous solution – this despite deliberate neglect of attractive interactions.

### Is Empathy Necessary for Morality?

#### Dr. Jean Decety | University of Chicago

Empathy, the ability to perceive and be sensitive to the emotional states of others, motivates prosocial and caregiving behaviors, plays a role in inhibiting aggression, and facilitates cooperation between members of a similar social group. This is probably why empathy is often and wrongly confused with morality. Morality refers to prescriptive norms regarding how people should treat one another, including concepts of justice, fairness, and rights. Drawing on empirical research and theory from evolutionary biology, psychology and social neuroscience, I will argue that our sensitivity to others’ needs has been selected in the context of parental care and group living. One corollary of this evolutionary model is that empathy produces social preferences that can conflict with morality. This claim is supported by a wealth of empirical findings in neuroscience and behavioral economics documenting a complex and equivocal relation between empathy, morality and justice. Empathy alone is powerless in the face of rationalization and denial. It is reason that provides the push to widen the circle of empathy from the family and the tribe to humanity as a whole.

### Shining a Light on the Next Generation of Solar Cells

####
November 21

Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

A lecture by

David Coffey

Candidate for the position in Physics

Within the grand search for greener energy sources, several new classes of solar cells are being pursued. One particularly attractive candidate is the organic solar cell, which one day might be printed as easily and cheaply as newspapers are today. However, the same properties that give this promise of easy manufacturing lead to extreme material disorder in current devices. As a result, discovering the physics mechanisms operating in these solar cells remains an area of intense research. In this talk I will describe recent efforts to gain this fundamental understanding including, 1) building new microscopes that can map the efficiency of these solar cells with extremely high resolution, 2) determining surface engineering techniques to control nanoscale structuring, and 3) designing organic solar cells so simple that even physicists can understand them.

### Seeing Under the Surface with Diffusing Photons

November 18

Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

A lecture by

Soren Konecky

Candidate for the position in Physics

Optical methods involving light scattering, spectroscopy, and imaging are ubiquitous in the study of materials ranging from dilute samples of atoms or molecules, to condensed media such as metals, semiconductors, and complex fluids. They are also integral tools in biology and medicine, as they allow us to study both the morphology and molecular composition of living organisms. However, more than a few hundred microns beneath the surface, optical methods which rely on ballistic light transport cannot be used to examine biological tissues, because all of the light that interrogates tissues at these depths is scattered multiple times. Accordingly, my research involves the development of new instrumentation and analytical methods to quantitatively determine the spatially varying optical properties of highly scattering media from measurements of multiply scattered light. This branch of optics is often referred to as “diffuse optics,” due to the fact that under certain conditions multiply scattered light propagates in a manner analogous to diffusion. Almost all biological processes and disease occur beneath the surface, and optical techniques have the potential to study them non-invasively, quantitatively, with high temporal and/or spatial resolution, and at low cost. For this reason, the study of diffuse optics is not only of fundamental interest, but also of great practical importance. In this seminar I will begin with a basic overview of diffuse optics. I will go on to describe my work developing Fourier domain and hyperspectral methods for diffuse optics, and how I am applying these methods to image brain function and disease.

### Dark Energy and the Big Lurch

####
November 10

Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

A lecture by

Peter Skiff

Physics Program

The discovery of an unexpected acceleration of the expansion of the cosmos led to the awarding of the 2011 Nobel Prize to Saul Perlmutter, Brian Schmidt, and Adam Reiss. While cosmic expansion (the continuous separation of galaxies and clusters) is neatly described by the use of Einstein’s General Theory of Relativity and Gravity, this acceleration is not (quite). The most popular of the current speculations involves a mysterious “dark energy” that was somehow lurking undetected in the13.5 billion year old cosmos until about 7 billion years after the origin, inflation, and “big bang” events began the evolutionary track. Apparently this dark energy comprises about 75% of the total matter and energy of the universe. This talk will review the expansion models and the techniques used to measure the galactic motions that led to this discovery, including the theory and observation of type Ia Supernovae. It will be descriptive (no mathematics), in order to be accessible to a general audience.

### Pencil + Tape = Topological Quantum Computation? The New Two-Dimensional Universe of Graphene

**PLEASE NOTE ROOM CHANGE

LECTURE BEING HELD IN RKC AUDITORIUM**

A lecture by

Paul Cadden-Zimansky

Candidate for the position in Physics

From its isolation in 2004 to last year's Nobel Prize, the impressive material properties of graphene have been widely touted: it's a single atom thick, stronger than steel, a better conductor than copper, and more transparent than glass. But what has intrigued many condensed matter physicists is the unusual charge carriers that can exist in graphene, particularly when it is subjected to high magnetic fields. These "particles" that inhabit graphene's two-dimensional universe can be relativistic, have fractional charge or multiple spins, and may even obey new types of quantum statistics. This talk will present recent experiments demonstrating some of these properties, and explain why the topological nature of these high-field carriers make them a potential building block for quantum computation.

### Visualizing Cancer Morphology Over Time and Space: Understanding Breast Cancer Progression through Mathematical Biology

####
October 13

RKC 111

A lecture by

Kerri-Ann Norton, '04

Department of BioMedical Engineering

Johns Hopkins School of Medicine

Breast cancer is one if the leading causes of cancer deaths in women. While breast cancer is a dynamic disease that may change morphology (shape) over time and depending on its placement within the tissue, diagnosis of the disease is usually accomplished by examining 2D slices of stained breast tissue and assigning the sample a grade and morphology. Unfortunately, the correlation between grade (a way of evaluating how irregular the nuclei look) and patient outcome is poor, depends on details of the classification method used, and is complicated by the frequent presence of multiple morphologies within a single sample. Here, I show two examples of how using mathematical biology provides insights into

the mechanisms that drive the disease and provides possible explanations for the difficulties in correlating morphology with patient outcome. Specifically, I use mathematical modeling techniques to study the progression of breast cancer over time under different cellular conditions and I use image processing to visualize the 3D morphology of breast cancer as compared to corresponding 2D slices. I find that differences in breast cancer morphology can result from different cancers with different cellular features or from cancers with the same cellular features at different time-points. I also find that early breast cancers with similar morphologies in 2D exhibit very different 3D morphologies. This work demonstrates the benefits of using mathematical and computational tools for studying cancer.

### Overview of Knot Invariants

####
September 22

RKC 111

A lecture by

Georgi Gospodinov

Bard College

Knot theory is central to low-‐dimensional topology and has many applications to physics, chemistry, biology, etc. We study knots up to isotopies, i.e., deformations that do not tear the knot or pass it through itself. So isotopic knots are thought of as the same. The question arises, given two knots, how can we tell if they are isotopic or not? Knot invariants are functions that assign an object (usually an algebraic object such as a number, a polynomial or a more complicated structure) to a knot. We use knot invariants to detect knots that are different, by studying the algebraic objects associated with the knots.

### Styrofoam Worlds and Planet-Eating Stars: An Update on the Search for Extrasolar Planets

####
September 15

RKC 111

A lecture by

Laurence A. Marschall

Professor of Physics, Gettysburg College

Until 1995, we knew of no solar systems like our own in the universe. Yet in the past few years nearly 500 planets have been discovered orbiting stars other than our Sun using telescopes here on Earth, and, in early 2011 NASA announced the discovery of more than 1000 planets discovered from the orbiting Kepler mission. In this presentation I'll describe how this sudden flood of discoveries came about, explore some of the oddest and most noteworthy new worlds that have been investigated so far, and review what we have learned about the structure and history of our own planetary system from observing these far more distant planets.

### A Tour of Operator Algebras

####
April 28

RKC 111

A lecture by

Jan Cameron

Vassar College

In this talk we will introduce the ﬁeld of operator algebras, currently one of the most exciting and widely applicable areas of mathematics. Our main objects of study are collections of linear transformations on vector spaces with special properties. Operator algebras possess both a rich algebraic structure, and a meaningful notion of distance, and as such have seen many natural connections to ﬁelds as diverse as signal analysis, geometry, group theory, and dynamical systems. We won’t cover all this ground; but we will look at a few of the most important examples of operator algebras, and conclude, if time permits, with a glimpse at some current research problems.

### Living in a Quotient Space

####
April 14

RKC 111

A lecture by

Marisa Hughes

Cornell University

A manifold is a space that locally "looks like" R*n*. The surface of the earth, for example, is a 2-manifold. In times past, our civilization was unable to distinguish this surface from the side of a cube; sailors feared that they may sail off the edge of the earth. In this talk, we will discuss what life would be like in other 2-manifolds and venture into higher dimensions. We will then begin folding these manifolds along certain symmetries to get a new (and often stranger) spaces. What do these spaces look like? How can we, as mathematicians, quantify the properties of life in a quotient space?

### Morse Theory: Smooth, Polyhedral and Discrete

####
April 7

RKC 111

A lecture by

Ethan Bloch

Mathematics Program

Morse theory is an important tool in the study of smooth manifolds, which are the higher-dimensional analogs of surfaces. For example, Morse Theory is used in the proof of the higher-dimensional Poincare Conjecture. The idea of Morse Theory is to analyze a manifold by looking at the critical points of smooth maps from the manifold to the real numbers. This talk will provide an elementary introduction to the basic idea of Morse theory, and will discuss some recent analogs of Morse theory in polyhedral and combinatorial settings.

This talk should be accessible to students who have taken Calculus III.
