1/23/2023 --- A mathematical model of regeneration-depletion dynamics and catastrophic events Speaker: Dr. Horia Petrache (Email: hpetrach@iupui.edu) Sponsored By: Joe Abell (ID: 737)

Complex physical systems often reach steady, persistent states followed by catastrophic events. Examples include market crashes, environmental disasters, depletion of resources, and loss of quantum information. This behavior is often unpredictable even when relevant factors are known. I will describe a stochastic mathematical model based on group structures that captures this particular type of behavior. The model shows how relatively long periods of apparent stability emerge followed by a sudden depletion of resources. One possible application of this model is in the development of computation methods for quantum computers which are currently under various stages of development.

1/30/2023 --- What Becomes of All Those Recyclables - Plastics Recycling, Inc. Speaker: Chad Smith and Alex Ramion (Email: Chad@plastic-recycling.net) Sponsored By: Linda Karwisch (ID: 732)

Finally learn what is being done to those plastic tubs, take home containers, lids, water bottles etc. Plastic Recycling, Inc. was established in 1988 and they are one of the largest providers of recycled plastic. The company makes supplies for the building industry and also customize compound materials to fit different business needs. Polystyrene blends, colored pellets and resin are the main products made from Polystyrene, Polypropylene, Homopolymer and Polyethylene.

2/6/2023 --- Heinrich Schliemann: archaeologist, tomb robber, and citizen of Indianapolis. Speaker: John Langdon (Email: langdon@uindy.edu) Sponsored By: John Langdon (ID: 1823)

Heinrich Schliemann (1822-1890) is best known as the discoverer of Troy. It is much less well known that he lived for a short time in Indianapolis and loved it. This colorful character excited the world about archaeology and to accept a historical basis of the Iliad, but his science was poor and irresponsible.
