- Graduate School Fall 2021: Fall degree window period deadline for doctoral students
- Time: 11:55 pm - 12:55 am
- Abstract: *Important Note: The “Window Period” is the time between the end of one degree period and the beginning of the next. You must have been registered for the previous semester (Fall, Spring, or Summer). If all degree requirements are met by the end of the window period, your degree will be granted for the following semester. However, you will not have to register or pay fees for the next semester.

- JAX MD: A Framework for Differentiable Atomistic Physics
- Time: 11:00 am - 12:15 pm
- Place: Online Seminar: Please sign up for our mailing list at www.physicsmeetsml.org for zoom link
- Speaker: Sam Schoenholz, Google Brain
- Abstract: I will talk about JAX MD, a software package for performing differentiable physics simulations with a focus on molecular dynamics. JAX MD includes a number of physics simulation environments, as well as interaction potentials and neural networks that can be integrated into these environments without writing any additional code. Since the simulations themselves are differentiable functions, entire trajectories can be differentiated to perform meta-optimization. These features are built on primitive operations, such as spatial partitioning, that allow simulations to scale to hundreds-of-thousands of particles on a single GPU. My talk will include an introduction to the JAX software package www.github.com/google/jax. If you are interested in trying out JAX MD, it is available at github.com/google/jax-md.

On November 8, 1895, Wilhelm Conrad Rӧntgen discovered a new invisible form of rays. He called them ‘X-Strahlen’ or X-rays. Since that day, X-rays have revolutionized medical imaging and science. Starting in the 1970s, powerful accelerator rings — the so-called synchrotrons — have dramatically advanced the scientific use of X-rays, by producing intense and highly-focused X-ray beams. Another quantum leap occurred in the late 2000s, when X-ray free-electron lasers came to light. These X-ray lasers produce ultra-short pulses with a brightness over one billion times larger than even the most powerful synchrotron sources. For the first time, scientists can study matter not just at the length scale of atoms and molecules, but also at the femtosecond (10-15 s) timescale of molecular motion. The dream of making molecular movies of a chemical reaction or a biological function in real time is becoming reality. We will describe these machines and present some of the most exciting examples of recent X-ray laser research.
The Discovery Building is at 330 N. Orchard St, Madison WI. Park for a small fee in Lot 20 at 1390 University Ave, Madison WI - Host: Department
Thursday, September 9th, 2021
- Astronomy Colloquium
- Show and Tell - One Slide to tell it all! Special Time: 3:00 - 3:45 pm, 4:00 - 4:45 pm.
- Time: 3:00 pm - 4:45 pm
- Place: 4421 Sterling Hall
- Speaker: Ellen Zweibel, UW Astronomy Department
- Abstract: This traditional "Show and Tell" colloquium is especially special this year because it will be the first in person since March 2020. Undergraduate researchers, grad students, postdocs, scientists, and faculty working in Astronomy are encouraged to introduce themselves in 2 minutes, accompanied by one (and only one) slide. This stringent format is necessary because there are so many of us. Even so, note the early start time and extra time alloted.
- Host: Ellen Zweibel
