Video Lectures

Recent observations by the Kepler space telescope have led to the discovery of more than 4000 exoplanet candidates consisting of many systems with Earth- to Neptune-sized objects that reside well inside the orbit of Mercury, around their respective...

The talk begins in 2005, with the unexpected discovery that massive early-type galaxies were extremely compact at redshifts z~2. It is now thought that the remarkable size growth of these galaxies from z=2 to z=0 is largely due to minor mergers; the...

In the last few years of the lives of massive stars, fusion in the core of the star produces a nuclear power that greatly exceeds the Eddington luminosity. This drives vigorous convection in numerous core and shell burning phases. I describe the...

Concinnitas is a collection of ten aquatints curated by Dan Rockmore and produced from the contributions of ten mathematicians and physicists in response to the prompt to transcribe their “most beautiful mathematical expression.” In this video from 2015, Robbert Dijkgraaf, Director and Leon Levy Professor, moderates a talk and Q&A with two contributors to Concinnitas, Enrico Bombieri and Freeman Dyson, as well as the portfolio curator, Dan Rockmore.

Environment plays a major in role in the evolution of galaxies. This is particularly true of low mass dwarf galaxies where more massive galaxies dramatically affect the local gravitational potential. Isolated galaxies offer a unique test bed for...

Cosmic rays comprise only about one billionth of interstellar particles in the Milky Way, but have as much energy as the thermal gas. Low energy cosmic rays affect the chemistry and thermodynamics of interstellar through collisional processes...
