Stuart D. Bale: The Origin and Structure of the Young Solar Wind: Parker Solar Probe ‘Touches the Sun

Dr. Stuart D. Bale of the University of California, Berkeley spoke to MSRI’s Math Lovers Forum (mathlovers.msri.org) in March 2022. This event was hosted by Ashok & Gita Vaish and David Eisenbud.

The Origin and Structure of the Young Solar Wind: Parker Solar Probe ‘Touches the Sun

The NASA Parker Solar Probe mission has now made 11 orbits of the Sun and currently has its periapsis at 13.3 solar radii; its Keplerian speed at periapsis is nearly 160 km/s (~360,000 mph), the fastest ever human-made object. Parker Solar Probe was designed and implemented to crack the outstanding problem of coronal heating and the acceleration of the supersonic solar wind. I will describe our latest advances, including insights to the discrete sources of solar wind and the recent entry into the solar ‘magnetosphere’, where the expanding wind is still in causal contact with the Sun.

Will M. Farr: Ringing Black Hole Bells and Other Exciting Results in Gravitational Wave Astronomy

Dr. Will M. Farr of Stony Brook University spoke to MSRI’s Math Lovers Forum (mathlovers.msri.org) in October 2021. This event was hosted by Ashok & Gita Vaish and David Eisenbud.

In the past few years, the exciting new field of gravitational wave astronomy has delivered many “firsts.” The first detection of gravitational waves—from a pair of black holes merging—in 2015; the first detection of gravitational waves from a merging pair of neutron stars—an event which also produced electromagnetic emission that was ultimately observed in various ways by ~30% of the global astronomical community—in 2017; the first detection of multiple gravitational wave “spectral lines” from a “ringing” black hole announced in 2019; and a number of “oddities” in 2020, including unusually massive black hole and neutron star mergers and a merger with one object larger than expected for a neutron star but smaller than expected for a black hole. 2020 also saw the first announcement of detections of a “mixed” merger between a neutron star and a black hole. Farr will discuss some of these exciting results in detail and explain the bright future of this fast-moving new field.

Benjamin Seibold: Traffic Waves, Vehicle Automation, and the Future of Traffic Modeling

Dr. Benjamin Seibold of Temple University spoke to MSRI’s Math Lovers Forum in February 2021. This event was hosted by Naren & Vinita Gupta, Ashok & Gita Vaish, and David Eisenbud.

Traffic Waves, Vehicle Automation, and the Future of Traffic Modeling

Vehicular traffic flow exhibits highly intriguing structural beauty (if one is not the one stuck in traffic): phantom traffic jams arise from dynamic instabilities; and traffic waves are mathematical analogs of detonation waves. We show how traffic models can expose these structures, and then present how existing vehicle automation can substantially reshape how traffic flows on our roadways.

Scott Aaronson: Quantum Computational Supremacy and Its Applications

Dr. Scott Aaronson spoke to MSRI’s Math Lovers Forum in October 2020.

Quantum Computational Supremacy and Its Applications

Last fall, a team at Google announced the first-ever demonstration of “quantum computational supremacy” — that is, a clear quantum speedup over a classical computer for some task — using a 53-qubit programmable superconducting chip called Sycamore. Google’s accomplishment drew on a decade of research in my field of quantum complexity theory. This talk discusses questions like: what exactly was the (contrived) problem that Sycamore solved? How does one verify the outputs using a classical computer? And how confident are we that the problem is classically hard — especially in light of subsequent counterclaims by IBM and others? Aaronson ends with a possible application that he’s been developing for Google’s experiment: namely, the generation of trusted public random bits, for use (for example) in cryptocurrencies.

Scott AaronsonScott Aaronson is David J. Bruton Centennial Professor of Computer Science at the University of Texas at Austin and director of its Quantum Information Center. He received his bachelor’s from Cornell University and his PhD from UC Berkeley. Before coming to UT Austin, he spent nine years as a professor in Electrical Engineering and Computer Science at MIT. Aaronson’s research in theoretical computer science has focused mainly on the capabilities and limits of quantum computers.

His first book, “Quantum Computing Since Democritus”, was published in 2013 by Cambridge University Press. He received the National Science Foundation’s Alan T. Waterman Award, the United States PECASE Award, the Vannevar Bush Fellowship, the Tomassoni-Chisesi Prize in Physics, and MIT’s Junior Bose Award for Excellence in Teaching.

David Eisenbud: How to Factorize (Almost) Everything / Jack McCauley

Dr. David Eisenbud and Jack McCauley spoke to MSRI’s Math Lovers Forum in November 2019.

How to Factorize (Almost) Everything

MSRI director and UC Berkeley Professor of Mathematics David Eisenbud recalls that most of us learn in high-school how to factor polynomials: for example, x2-y2 = (x+y)(x-y), and x2+2xy+y2 = (x+y)2. Some of us also learn that factoring y2-x3 is impossible.  However, it is a long tradition in mathematics that one can solve more problems if one widens one’s point of view. David will show how such a widening allows one to factor nearly any. He’ll also share an open problem in the area that touches on the very nature of complexity.

Random Walks and Gerrymandering

Markov chain Monte Carlo, or MCMC, is a powerful family of search algorithms that has applications all over science and engineering.  I’ll make the case that it gives us the material for a major breakthrough in the study of redistricting:  how do you decide when a map has been gerrymandered?

Math Lovers Forum at MSRI: Moon Duchin on “Random Walks and Gerrymandering” from MSRI on Vimeo.

DuchinMoon Duchin is an Associate Professor of mathematics at Tufts University and serves as director of Tufts’ interdisciplinary Science, Technology, and Society program. Her mathematical research is in geometric group theory, low-dimensional topology, and dynamics. She is also one of the leaders of the Metric Geometry and Gerrymandering Group, a Tisch College-supported project that focuses mathematical attention on issues of electoral redistricting.

Duchin’s research looks at the metric geometry of groups and surfaces, often by zooming out to the large scale picture. Lately she has focused on geometric counting problems, in the vein of the classic Gauss circle problem, which asks how many integer points in the plane are contained in a disk of radius r. Her graduate training was in low-dimensional topology and ergodic theory, focusing on an area called Teichmüller theory, where the object of interest is a parameter space for geometric structures on surfaces.

Duchin has also worked and lectured on issues in the history, philosophy, and cultural studies of math and science, such as the role of intuition and the nature and impact of ideas about genius. She is involved in a range of educational projects in mathematics: she is a veteran visitor at the Canada/USA Mathcamp for talented high school students; has worked with middle school teachers in Chicago Public Schools, developed inquiry-based coursework for future elementary school teachers at the University of Michigan, and briefly partnered with the Poincaré Institute for Mathematics Education at Tufts.

The least interesting philosophical theory of probability ever (but at least it makes sense)

I will present a new way to look at the scientific laws of probability. I will argue that:
(i) The existing philosophy of probability is a complete intellectual failure.
(ii) The two most popular philosophical theories of probability formalize
only those beliefs that were never disputed.
(iii) The non-formalized parts of probability are swept under the rug of absurdities.
(iv) Even the justifications of the non-controversial beliefs are nonsensical.
You can watch the event video below.
