The universe is YUGE, but much of what makes it tick happens at an infinitesimally small scale. We will talk about how we can change what happens at the ultra-small scale simply by observing it, and about the impressive tools we use to observe the universe in action over massive distances. We promise that no real cats will be harmed, though some imaginary cats will have a very good AND bad time.
Observing and Understanding the Universe
Xianming Han, PhD, Professor of Physics, Butler University
Since ancient times, human beings have been observing the stars in the sky, and trying to understand the universe. In this talk, we will examine the tools that we have used in the past and tools that we will use in the future for astronomical observations and the various theories that we have developed about the universe.
To be and Not to be: Nine Lives of the Schrodinger Cat
Since the antiquities, the notion of realism — that there is a reality “out there”, with properties that are independent of an observer — is well established in the human thought. It is based on the unstated assumption that one can make observations without disturbing what is being observed. Quantum theory, which describes nature at micro- or nanoscale, upends this conventional wisdom. I will discuss the surprising effects that arise when the process of observation inherently affects the system.
Black Acre Brewing Company is a cornerstone of East Indy culture. They are a favorite partner because of their love of science and excellence in brewing. We will be talking science among the active fermenters and brightening tanks that bring us our Black Acre favorites. Cold brews will be available for purchase. Feel free to bring in food if you’re hungry from the nearby Jockamo’s Pizza or The Mug (just across the street -- try the tenderloin). Grab a pick-me-up on the way at Coal Yard Coffee right on Bonna Ave (NOT THE TAPROOM) in front of the facility before the event. Doors at 6:30, event starts at 7. 5529 Bonna Ave -- look for our signs and traffic director on Bonna.
