The Dirac Lectures is an initiative of Florida State University to celebrate the memory of Paul Dirac, late FSU Physics faculty member, Nobel prize laureate, and namesake of the Dirac Science Library. These lectures bring outstanding speakers to FSU to present physics topics of particular interest and notability.
2025 Dirac Lectures on Beyond the Λ-CDM Model
The 2025 Dirac Lecture series is dedicated to the subject of Beyond the ΛCDM Model with a special focus on tensions that have emerged between cosmological and astrophysical data and the standard cosmological model. The lectures will be held at the Department of Physics at Florida State University on April 16-18, 2025. You can find a printable version of the poster HERE.

Special Public Lecture
|
| Adam Riess |
| Johns Hopkins University |
On Thursday April 17th, 2025, Nobel Laureate professor Adam Riess will deliver the lecture The Surprising Expansion History of the Universe. This special lecture is open to the general public and will take place at 7:00pm in the Auditorium at the FSU Department of Earth, Ocean & Atmospheric Science (EOAS).
During the lecture professor Riess will describe how his team discovered the acceleration of the Universe and why understanding the nature of so-called "dark energy" presents one of the greatest remaining challenges in astrophysics and cosmology. He will also discuss recent evidence that the Universe continues to defy our best efforts to predict its behavior.
