Presidential Lectures are a series of free public colloquia spotlighting groundbreaking research across four themes: neuroscience and autism science, physics, biology, and mathematics and computer science. These curated, high-level scientific talks feature leading scientists and mathematicians and are designed to foster discussion and drive discovery within the New York City research community. We invite those interested in these topics to join us for this weekly lecture series.
Naturalist John Muir wrote, “When we try to pick out anything by itself, we find it hitched to everything else in the universe.” There’s no better illustration of Muir’s observation than the fluid Earth system.
In this Presidential Lecture, Brad Marston will discuss a surprising connection recently discovered between the atmosphere and quantum physics. Observations of the stratosphere reveal non-trivial topology, providing us with a new perspective on the origin of certain waves that travel around the equator and drive oscillations in the climate. The atmospheres of other worlds, he says, may likewise be viewed as topological insulators.
