Physics Colloquium : "Minkowski, Relativity and Einstein's Changing Attitudes to Mathematics"

Location: 
Levin building, Lecture Hall No. 8
Mon, 04/11/2019 - 12:00 to 13:30

Lecturer: Leo Corry - Tel Aviv University
Abstract:
Two years after Einstein’s relativity paper of 1905, Hermann Minkowski (1864-1909)
undertook the reformulation of the new theory in mathematical terms that were to
become its standard language, and that allowed its further development. Einstein’s initial
attitude towards Minkowski’s approach was rather unsympathetic, and it reflected a more
general attitude of him towards mathematics and its role in physics. Still, it was not long

Physics Colloquium : "The Origin of Gold (and other R-process elements)"

Location: 
Levin building, Lecture Hall No. 8
Mon, 28/10/2019 - 12:00 to 13:30

Lecturer: Tsvi Piran, The Hebrew University
Abstract:
The origin of the heaviest neutron rich elements has been a long standing puzzle. The
nucleosynthesis of these elements requires a neutron rich environment to enable the so
called rapid capture (r-) process. For years it was believed that these elements are
synthesized in supernovae. However in recent years evidence accumulated in favor of the
binary neutron star mergers as the dominant r-process sites. This was dramatically

Physics Colloquium : "Can physics help us understand cancer metastasis?"

Location: 
Levin building, Lecture Hall No. 8
Mon, 24/06/2019 - 12:00 to 13:30

Lecturer: Prof. Herbert Levine, Northeastern University
Abstract:
Until very recently, most cancer biologists operated with the assumption that the most common route to metastasis involved cells of the primary tumor transforming to a motile single-cell phenotype. This change allowed them to migrate individually to distant organs, eventually leading to clonal growths in other locations.

Physics Colloquium : "Room-temperature quantum memories from nanoseconds to hours"

Location: 
Levin building, Lecture Hall No. 8
Mon, 17/06/2019 - 12:00 to 13:30

Lecturer: Dr. Ofer Firstenberg, Weizmann Institute of Science
Abstract:
Warm atomic gasses are among the simplest quantum systems, offering real-life applications in deployable millimeter-size devices. They can strongly couple to optical fields and exhibit superb coherence properties at or above room temperature. Indeed, atomic gasses are at the heart of miniature atomic clocks and inside the most sensitive magnetometers and gyroscopes.

Physics Colloquium : "The physics of crushing and smashing"

Location: 
Levin building, Lecture Hall No. 8
Mon, 27/05/2019 - 12:00 to 13:30

Lecturer: Prof. Shmuel Rubenstein of Harvard University
Abstract:
Understanding the physics of irreversible processes that occur in far from equilibrium systems is of both fundamental and practical importance. However, these problems pose unique challenges as dynamic irreversible processes are far from steady and probing them requires keeping up with them as the system navigates across a complex landscape. Such challenges, as they manifest in turbulence, were beautifully portrayed by Richardson:
