Mysteries of the Higgs Boson, ABSTRACT: Thirty-five years after it was postulated as a key component of the theory of weak interactions, the Higgs boson was discovered at the CERN Large Hadron Collider in 2012. Since that time, the major couplings of the Higgs boson have been measured at the LHC, with results in good […]
TITLE: New perspectives on the cold neutral interstellar medium: from the Milky Way to nearby galaxies, ABSTRACT: The neutral interstellar medium (ISM) is a vital player in the star formation process, based on its major contribution to the ISM's mass, and bears the brunt of the stellar feedback. In particular, the diffuse ISM is not […]
Title: Precision measurements are having a moment: recent results in leptons and why they matter, Abstract: The past three years have seen three dipole-moment measurements of record-breaking accuracy – the magnetic dipole moments (aka “g-2”) of the muon and of the electron, and the electric dipole moment (EDM) of the electron. I will focus at first […]
TITLE: Looking for Fossils of the Big Bang 2025 Ferdinand G. Brickwedde Lecture in Physics
TITLE: Precision measurement in tabletop experiments, Abstract: Many theories of physics beyond the Standard Model predict small deviations from Standard Model behavior at low energy scales. We can search for such deviations by performing precision measurements in "tabletop" experiments. In this talk, I will describe some of the frontiers of research in this field. I […]
Hosted by JHU Gender Minorities & Women in Physics (G-WiP). Donna Strickland is a professor in the Department of Physics and Astronomy at the University of Waterloo and is one of the recipients of the Nobel Prize in Physics 2018 for developing chirped pulse amplification with Gérard Mourou, her PhD supervisor at the time.
Title: New Photo-galvanic effects, Abstract: The conventional device to convert light to electrical current uses two different kinds of doped silicon merged together known as pn junction or heterostructures. The current only flows one way in the pn junction due to a built-in electric field. Fabricating such heterostructures requires sophisticated thin film deposition methods. In […]
TITLE: A Physicist Following Faraday's Hint in the Search for Quantum Gravity, ABSTRACT: Faraday's discovery of electromagnetic induction occurred due to his inference that magnetic fields about wires must be as wheels about a spoke. This visualization led to understanding the physics of B-fields. Currently mathematically enabled research uses computers to augment this important tool. The speaker will discuss […]
TITLE: Learning to navigate complex environments ABSTRACT: Living systems face the challenging task of navigating complex natural environments. Notable examples include long-distance orientation using airborne olfactory cues transported by turbulent winds, the tracking of surface-bound trails of odor cues, and flight in the lowest layers of the atmosphere. Terrestrial animals, insects, and birds have evolved […]
TITLE: The Legacies of Hubble, Webb, and future NASA astrophysics flagship missions ABSTRACT: For the past four decades, the Space Telescope Science Institute has served as the bridge between NASA's flagship astrophysics missions and the scientific community through its role as the science operations center for Hubble, Webb, and Roman. The Hubble Space Telescope is […]
TITLE: The Impossible Man: Roger Penrose and the Cost of Genius, ABSTRACT: Patchen Barss will discuss his new biography of Roger Penrose, in conversation with Sean Carroll (JHU)
Hosted by JHU Gender Minorities & Women in Physics (G-WiP), TITLE: A new vision for the Center for Astrophysics | Harvard & Smithsonian ABSTRACT: I will present the latest discoveries and developments at the Center for Astrophysics | Harvard & Smithsonian (CfA). Our discoveries cover solar astrophysics, star formation and evolution, galaxy formation & evolution, extrasolar […]
