- Bach's integration of complexity and simplicity
- Time: 12:05 pm - 1:00 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Trevor Stephenson, Harpsicord
- Abstract: Part of the miracle of Bach’s music is that no matter how contrapuntally layered and complex a piece becomes, the idea and the meaning are never lost. Using several examples from Bach’s The Well-tempered Clavier, I will bring play and discuss how Bach achieves clarity within extremely complex systems. I'll also look at how Bach deals with near-chaotic material, such as the fugue subjects that approach a-tonality; we'd look at how he breaks down a sense of key, and then rebuilds it. I’ll also show how the unique tuning (tempering) method for the The Well-tempered Clavier assists in giving each piece a unique acoustic color. I’ll bring my 17th-century Flemish harpsichord for the presentation.

- Hyperpolarized Spins in Nanodiamond
- Time: 10:00 am
- Place: 5310 Chamberlin Hall
- Speaker: Ewa Rej, University of Sydney
- Abstract: Nanodiamond is emerging as a platform for the development of nanoparticles for personalized medicine, based on its unique quantum mechanical properties, biocompatibility, and rich surface chemistry. Although diamonds have already been used for drug delivery of chemotherapeutics, and as optical sensors of sub cellular processes, a means of non-invasively detecting these nanoparticles in-vivo is still lacking.
I will present work towards developing nanodiamond as a new bioagent for MRI. By increasing the 13C nuclear spin polarization in diamond, we boost the detectable NMR signal by several orders of magnitude. These hyperpolarization techniques, combined with the long T1 relaxation times of up to an hour in nanodiamond, open the possibility of using standard MRI techniques to image small concentrations of nanoparticles over long time scales.
I will also present work examining T2 spin-spin relaxation times, demonstrating how T2 can increase by three orders of magnitude using hyperpolarization combined with dynamical decoupling sequences.

- Physical Conditions in the Cold ISM of Nearby Galaxies and Their Relation to Star Formation
- Time: 3:30 pm - 5:00 pm
- Place: 4421 Sterling Hall, Coffee and Cookies at 3:30 PM. Talk begins 3:45 PM
- Speaker: Adam Leroy, Ohio State University
- Abstract: I will present results from several new projects using ALMA, the IRAM mm-wave telescopes, and soon the Green Bank Telescope to map physical conditions in the molecular gas of nearby galaxies. Using multi-line spectroscopy we are able to constrain the gas density distribution in each part of the galaxy, while using high resolution CO imaging we can measure the structure (density, turbulence, and self-gravity) of the interstellar medium on the scale of individual star-forming clouds. The ability to make such measurements over a large part of a star forming galaxy is new in the last few years, thanks to the IRAM programs EMPIRE and PAWS, the beginning of ALMA operations (and our PHANGS CO survey), and upgrades to the GBT. I will show how the amount of dense gas changes across the disk of galaxies, and illustrate a more nuanced role for gas density in star formation than commonly asserted. I will also show how the basic cloud-scale structure of the cold interstellar medium changes from galaxy-to-galaxy, reflecting the local environment, and I will show how these local structural conditions relate to gas density and star formation in the best studied nearby galaxies. Finally, I will highlight first results several new surveys with ALMA (as part of the PHANGS collaboration) that promise to give us a sharp new view of cold gas in nearby galaxies over the next years.

- Physics Department Colloquium
- ****NOTE SPECIAL START AND END TIMES: 3:00 - 5:00 PM****
- Breaking the Bias Habit
- Time: 3:00 pm - 5:00 pm
- Place: 2241 Chamberlin hall
- Speaker: Jennifer Sheridan & Prof. Molly Carnes, UW Madison
- Abstract: This two-hour workshop introduces the concepts of unconscious biases and assumptions about gender by treating the application of such biases as a "bad habit." Attendees will uncover their own biases through use of an Implicit Association Test, will discover the underlying concepts and language used in the psychological and social psychological literature to describe such processes, and will be provided with proven strategies for reducing the application of these biases.
