Edmund R. Michalik has a long history with the University of Pittsburgh and the Department of Mathematics. He received his BA in education from Pitt in 1937 and went on to receive his MS in mathematics in 1940. After he graduated, Michalik joined the Navy to serve during WWII. The day after he was discharged in 1946, he met his future wife, Martha. He came back to teach at Pitt until 1951. Over the next few years Michalik worked for a variety of organizations, including the Army, Atlantic Research Corporation and the Department of Mathematics at the Mellon Institute, where he was the head of applied mathematics. In 1957 he worked for PPG as the head of the applied mathematics, and later as the senior engineer and head of computer research, when he retired in 1980. Throughout this time Michalik volunteered his time and taught as an adjunct professor in the Department of Mathematics. He was dedicated to the study of mathematics.
Thanks to the generosity of the Michalik family and in honor of Edmund R. Michalik, the Department of Mathematics this semester brought Professor Martin Nowak to Pitt for two exciting events that provided a mathematical connection with Pitt's "Year of the Healthy U" theme. Nowak is a Professor of Mathematics and Biology and the Director of the Program for Evolutionary Dynamics at Harvard University. He is a world expert on evolutionary game theory (e.g, including the evolution of cooperation and other altruistic-seeming behaviors), population structures, cancer dynamics and treatment, and a range of other topics. He has written several hundred articles and has published books on virology, evolutionary dynamics, and cooperation.
On Wednesday, March 21st, Dr. Nowak was joined by Dr. Gilles Clermont (Pitt Critical Care Medicine and long-time collaborator of several current Pitt Mathematics faculty), Dr. David Galloway (Pitt Public Health Dynamics Lab), and Dr. Wilbert Van Panhuis (Pitt Epidemiology/Biomedical Informatics) for a panel on "Computational Methods for Fostering a Healthy Community". This event was organized by the Department of Mathematics and was moderated by Dean Donald Burke from Pitt's Graduate School of Public Health. The panelists discussed mathematical modeling of the complex interacting feedback loops associated with the immune response, the use of the FRED (A Framework for Reconstructing Epidemiological Dynamics) agent-based modeling system to predict geographic spread of disease outbreaks, the Project Tycho open-access global database of disease-related information, and how mathematical analysis of cancer as an evolving system can be used optimize cancer treatments. They also took questions from an audience eager to understand how mathematics and data can combine to revolutionize how we study and improve community health.
On Thursday, May 22nd, Dr. Nowak gave the Edmund R. Michalik Distinguished Lecture on "Evolutionary Dynamics". Nowak outlined principles of evolution, listing familiar ones such as mutation and selection but also proposing that cooperation belongs on the list as well. He discussed how mathematical frameworks, such as Moran or birth-death processes, graph theory, and evolutionary game theory (related to the methods applied in economics by famed mathematician John Nash), can be used to study the selection process. In particular, his mathematical analysis illustrated how certain patterns of interactions among individuals can allow a population to gain maximal advantage from cooperation. The lecture was well attended, with faculty and students both well represented in the audience, and led to interesting discussions about language, artificial intelligence, and, of course, the role of mathematics in understanding the living world.

Prof. Frank Morgan
Soap Bubbles, Tilings, and Other Partitioning Problems
March 22, 2013 at 4 p.m.
Ballroom B, University Club at the University of Pittsburgh
Abstract: The Ancient Greeks proved that the circle is the least-perimeter way to enclose given area.Similarly the round soap bubble provides the least-perimeter way to enclose a given volume of air, although that was not proved until 1884 by Schwarz. Similarly the double bubble that forms when two soap bubbles come together is the least-perimeter way to enclose and separate two given volumes of air, although that wasn't proved until 2000 by Hutchings, Morgan, Ritoré, and Ros.
Lord Kelvin sought the least-perimeter way to divide all of space into unit volumes, and his conjecture stood for 100 years, until Weaire and Phelan found a better way in 1994. Whether their new candidate is best remains open today. Even the least-perimeter way to divide the plane into unit areas, using the bees' hexagonal honeycomb tiling, though conjectured by the Ancient Greeks, was not proven until 1999 by Hales. The most efficient tiling by pentagons remains open.
In many simple nonEuclidean possible universes, even the ideal shape for a single soap bubble remains open.
Prof. Shing-Tung Yau
Geometry: from Riemann to Einstein and on to String Theory"
October 5, 2012
Shing-Tung Yau has made fundamental contributions to differential geometry which have influenced a widerange of scientific disciplines, including astronomy and theoretical physics. Yau’s first major contribution to differential geometry was his proof of the Calabi conjecture, which concerns how volume and distance can be measured not in four, but in five or more dimensions. In 1979 Yau and Richard Schoen proved Einstein’s positive mass conjecture by applying methods devised by Yau. The proof was based on their work with minimal surfaces. In 1982 Yau was awarded the Fields Medal, the highest award in mathematics, and in 1994 he shared with Simon Donaldson of Oxford University the Crafoord Prize of the Royal Swedish Society, in recognition of his “development of nonlinear techniques in differential geometry leading to the solution of several outstanding problems.” In 2010 Yau published the book The Shape of Inner Space.
Sir Roger Penrose
"Can We See Through the Big Bang into Another World?"
January 24, 2011
Prof. Sir Roger Penrose has made many contributions to the fields of Mathematics and Physics. He proved that singularities (such as black holes) could be formed from the gravitational collapse of immense, dying stars and invented spin networks which later came to form the geometry of spacetime in loop quantum gravity. Prof. Penrose is also well known for his 1974 discovery of Penrose tilings, which are formed from two tiles that can only tile the plane non-periodically, and are the first tilings to exhibit fivefold rotational symmetry. He is the recipient of many awards and honors, including a Royal Medal from the Royal Society and a Wolf Prize, which he shares with Stephen Hawking. Prof. Penrose’s book "The Road to Reality" gives a comprehensive guide to the laws of physics. His latest book is "Cycles of Time."
