Advances in Timekeeping
The Academy’s 2017 Outstanding Scientist Innovation Award recipient, Kater Murch, Ph.D., along with Washington University Arts & Sciences graduate student Mahdi Naghiloo and theory collaborator Andrew Jordan of the University of Rochester use a superconducting quantum system to discover a quantum speedup in frequency measurement. The discovery in timekeeping has applications for enhanced MRI medical imaging devices, the analysis of light emitted from stars, and clock precision. Source: Washington University in St. Louis

Kater is the featured speaker at the Academy’s February Science Seminar, The Arrow of Time in Quantum Measurement, at the Saint Louis Zoo on Wednesday, February 7 at 7 p.m. The event is free and open to all.

The American Paradox: Rising Inequality in an Age of Prosperity

January 23 7:00 pm – 8:30 pm

Registration not required. FREE and OPEN to ALL. Middle and high school students welcome. Parking is free in the History Museum lots, on the street in Forest Park, or in the East and West lots across from the Judith and Dennis Jones Visitor Center. Featured Speaker: Mark R. Rank, Ph.D., Herbert S. Hadley Professor of Social Welfare, George Warren Brown School of Social Work, Washington University in St. Louis A fundamental paradox of American society today has been the rise of inequality and vulnerability within an overall age of economic prosperity. Mark Rank, the Herbert S. Hadley Professor of Social Welfare at Washington University in St. Louis explores the dynamics and consequences of this troubling pattern, and what it may mean for Americans in the future. The American Paradox is being presented in conjunction with the Missouri History Museum exhibition, #1 in Civil Rights: The African American Freedom Struggle in St. Louis on display at the Museum thru April 15, 2018.

The Arrow of Time in Quantum Measurement

February 7 7:00 pm – 8:30 pm

Free and OPEN to ALL. Junior Academy members and middle and high school students are welcome and encouraged to attend. Reservations not required. Parking is free in the Zoo North lot or on the street in Forest Park. Featured Speaker: Kater Murch, Ph.D., Assistant Professor, Department of Physics, Washington University in St. Louis; 2017 Outstanding St. Louis Scientist Innovation Award recipient, The Academy of Science - St. Louis What can quantum measurement tell us about the arrow of time? To answer this question, we use cutting edge techniques involving superconducting circuits cooled to near absolute zero to capture “movies” of quantum behavior. In this fascinating talk on our quantum world, physics professor, Kater Murch, shares these captured quantum movies and discusses how we can infer an arrow of time from quantum measurement alone.
