### 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.

### Seating Arrangements, Domino Tilings, and Graph Factorials

#### Amir Barghi, Mathematics Program

At a dinner party, each guest is assigned a seat along a long table, which seats 12 people. However, when all guests arrive, they decide to change things a little up by swapping seats. In order to minimize the amount of chaos, they have to follow the following three rules: a guest can keep their seat; two guests sitting next to each other or across the table can swap seats; three or more guests can swap seats in a cyclic

fashion, provided that each person is moving one seat to the left or to the right or across the table. Assuming that all guests have showed up, how many possible seating rearrangements are there? Now consider the graph on the left. We want to place dominoes along some of the edges of this graph so that each vertex is covered by exactly one domino. We call any such placement of dominoes a domino tiling. How many domino tilings of this graph exits?

In this talk, we will explore the connection between these two problems by defining what the factorial of a graph is.

Prerequisites: A familiarity with graphs and counting arguments is a plus, but not

required.

### Next-generation Atomic Clocks:

Harnessing Quantum Matter to Study Gravity and Search for Dark Matter

#### Edward MartiJoint Institute for Laboratory AstrophysicsUniversity of Colorado

The accuracy of atomic clocks has improved a thousandfold over the last 15 years. The latest generation of atomic clocks, called "optical lattice clocks", can detect changes in general relativity's gravitational redshift over a few centimers. These clocks use extremely stable lasers to count the "ticks" of an optical-frequency transition in atoms cooled to the nanokelvin regime, reaching 18 digits of accuracy in a few hours. In this talk, I will discuss how we achieve this accuracy through exquisite control of the quantum mechanical state of these ultracold atoms, and how we are using these clocks to search for dark matter and test relativity.

### Galactic Exploration with Invisible Light

#### Daniel Marlow, Princeton University

Radio astronomy has greatly enhanced the range of observable astronomical phenomena. Although a wide range of wavelengths are used in radio astronomy, one of the most important is 21 cm, which corresponds to the hyperfine transition in atomic hydrogen. Although the 21 cm signal from a small collection of hydrogen atoms is exceedingly weak, and the density of hydrogen in the Milky Way is very low, the Galaxy is a big place and contains enough hydrogen to produce a signal that can be detected with a modest terrestrial apparatus. In this talk, I will present results obtained at 21 cm with a recently refurbished cold-war-era 60-foot dish antenna. Data from the dish will be used to measure the Sun's velocity with respect to the average velocity of nearby stars and to infer the existence of dark matter. Time permitting, pulsar signals will be presented and schematic plans for a kit capable of detecting indirect evidence for dark matter for costing less than $1000 will be presented.

### Chaos and Network Synchronization

####
December 12

Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

A lecture by

Lucas Illing

Candidate for the position in Physics

Time-delayed coupling and self-feedback occurs in many systems and is particularly important at high speeds, where the time it takes signals to propagate through device components is comparable to the time scale of the signal fluctuations. A fascinating feature of systems with delay is that even seemingly simple devices can show exceedingly complex dynamics such as chaos. I will talk about the generation of high-speed chaos using optoelectronic time-delayed feedback oscillators and discuss a particularly intriguing form of collective behavior that arises when several such oscillators are coupled to form a network. Under certain conditions the entire network will oscillate in synchrony, in spite of the signal propagation delays in the coupling links.

### Collecting Electrons from Bacteria with Microbial Fuel Cells

####
December 5

Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

A lecture by

Emily Gardel

Candidate for the position in Physics

The energy for all forms of life comes from the flow of electrons in energetically favorable pairings of oxidation and reduction reactions. While humans can only use oxygen as an electron acceptor, bacteria have the ability to use a variety of compounds, including solid materials, such as metal oxides. This metabolic diversity makes these micron-sized organisms dominant members of our biosphere and opens possibilities for biotechnological applications, including electricity production, bioremediation, and wastewater treatment. In my research, I focus on bacteria that are capable of transferring electrons outside the bacterial cell to a solid-phase electron acceptor. I will discuss how this phenomenon can be studied by separating the locations of the oxidation and reduction reactions while providing an electrode as an electron acceptor for the bacteria. These microbial fuel cells (MFCs) produce an electrical current and there is interest in understanding the limiting factors governing overall power performance in these systems. Using an environmental MFC, I have found that current production decreases when the system is mass-transfer limited. By allowing the electrode to rest disconnected from electron flow, any necessary nutrients or electron donors diffuse to the bacteria on the electrode and allow for increased current production upon reconnecting the electrode. These findings demonstrate a method for determining an optimal way for operating MFCs used for electricity generation as well as raise additional questions about bacteria-electrode electron transfer.

### All I Really Need to Know I Learned from Triangles

####
March 15

Hegeman 308

Joshua Bowman

SUNY Stony Brook

Flat surfaces (such as a cube or tetrahedron with the vertices removed) show up in a variety of mathematical areas. Their structure can be studied using Delaunay triangles, which in most cases are uniquely determined by the surface. As a surface is deformed, its Delaunay triangles change, and the way in which they change can give us a surprising amount of information about the surface. The only prerequisites for this talk are knowing what a

2x2 matrix is, and a certain level of comfort with abstract constructions.

### Orthogonal Maximal Abelian Subalgebras of the n x n Matrices

####
March 8

Hegeman 308

A lecture by

Jan Cameron

Vassar College

Though the terminology may be unfamiliar, you have certainly seen a maximal abelian self-adjoint subalgebra (masa) of the complex matrices in your linear algebra course: the algebra of diagonal matrices. The notion of orthogonality for a pair of masas in M_n(C) is simple to describe, but surprisingly deep and relates to many areas of mathematics. In this talk, we'll consider the fascinating and important open problem of nding complete sets of pairwise orthogonal masas in the n x n complex matrices. We'll look at a few dierent ways to think about the problem, as well as why one might be interested in a solution, and an assortment of related questions. If time permits, I'll talk a bit about how orthogonal masas have come up in current research on structure theory of nite von Neumann algebras.This talk will be accessible to anyone who has had a course in linear algebra

### Making the Most of Euler's Formula

####
March 1

Hegeman 308

Kristin Camenga

Department of Mathematics

Houghton College

Most people remember working with polyhedra in elementary and high school: cubes, prisms, tetrahedra, pyramids, etc. Euler's formula states that if V is the number of vertices, E the number of edges and F the number of faces of a polyhedron, V + F = E + 2. This is a beautiful and useful formula - but can't we do more? Can we get a similar theorem if we change some of our hypotheses? How does Euler's formula change if we allow polyhedra to be in dimension 4 or 5 or n? What if we look at angles of polyhedra instead of the number of faces? We will look at a number of examples as we generalize Euler's formula in these directions and others. We will end with a glimpse of open questions about angles in polytopes. No specific math background will be assumed, but curiosity is expected!

### Symmetries of Julia Sets

####
February 23

Hegeman 308

James Belk

Mathematics Program

Bard College

A fractal is a mathematical shape that exhibits the same structure at a range of different scales. Among the most famous fractals are the Julia sets, which arise in a simple way from polynomials and complex numbers. In this talk, I will introduce Julia sets and discuss some of their basic properties. I will then indicate a connection between Julia sets and certain groups of functions on the unit circle. This talk should be accessible to students who have taken Proofs and Fundamentals. Some familiarity with groups would be helpful, but is not necessary.

### The History and Arithmetic of Legendre Polynomials

####
February 16

Hegeman 308

A lecture by

John Cullinan

Mathematics Program

The Legendre Polynomials are orthogonal polynomials that have deep connections to mathematical physics. For example, they arise when solving the Laplace equation in spherical coordinates. It is also the case that the Legendre Polynomials are extensively studied for their number-theoretic properties. In this talk we will describe some of these properties as well as discuss some open questions surrounding the Legendre Polynomials. This talk should be accessible to students who are currently taking Proofs and Fundamentals (though some group theory will be used at the end).

**MATH TEA**The weekly Math Tea will immediately follow the seminar. Join us for tea and refreshments at 4:30 in the Albee 3rd floor Math Lounge.
