What Physicists Do
Physics 123 Spring 2018
(First 5 weeks) Fridays, 6a (3:30-4:30), Olin 141 1 Credit; S/CR/NC
The Department of Physics and Astronomy is pleased to announce this year’s Physics 123 Line-up. “What Physicists Do” is our annual series of five lectures by invited speakers, many of whom are Carleton Physics alumni. It is intended to introduce students to a broad range of real-world physics and to give some perspective on the kinds of work done by people with a physics background. The course is open to all interested students who have taken PHYS 151; those considering a major in physics are particularly encouraged to enroll.
The presentations are in OLIN 141 on Fridays during 6th period (3:30-4:30pm). The only requirement, beyond attending five talks, is to read an assigned article beforehand and then to submit a short (one page) typed essay afterwards commenting on both the talk and the reading. Speakers will be available for informal discussions over refreshments afterward. Questions: Arjendu Pattanayak, Olin 337, x7166, arjendu@carleton.edu
April 20 Emily Petroff ‘12 “Fast radio bursts: our newest cosmic mystery”
Most things in the universe happen over millions or even billions of years but some things change on the timescales of human life and can be seen to change in a matter of months, days, or even seconds. These sources are called transients and are some of the most extreme events in the Universe, things like the collapse of a dying star, or a collision of two massive objects. With recent advances in telescope power and technology, astronomers are observing more and more transients each year and even finding new types. In 2007 we discovered a brand new type of transient called fast radio bursts (FRBs), bright radio pulses that last only a few milliseconds. Their origin is one of the newest unsolved mysteries of astronomy but it is clear they are produced in tremendously energetic processes, possibly even billions of light years away. I will talk about some of the exciting new work happening in this area, where niche fields like this fit in the broader context of astronomy, and what it is like to use a physics degree in astronomical research specifically and academia more generally.
