Symmetries of Time Lecture - Professor Frank Wilczek, 2004 Nobel Laureate: Feb. 13, 2020. Garren Auditorium. Reception starting at 3:30.

Speaker:  Professor Frank Wilczek, 2004 Nobel Laureate.   Date: Feb. 13, 2020.  Garren Auditorium.  Reception starting at 3:30. Title: Symmetries of Time   Abstract: Time displays two fundamental symmetries: time reversal, T, and time translation, Τ (Tau).  They inspire fruitful questions: Why is T very accurate, but not quite exact?  Can Τ (Tau)  be broken spontaneously?   Those questions lead into axions and time crystals, respectively, two subject...

Surprising Beauty Found in Bacterial Mixtures E. coli and A. baylyi form intricate flower patterns under the microscope

Microbial communities inhabit every ecosystem on Earth, from soil to rivers to the human gut. While monoclonal cultures often exist in labs, in the real world, many different microbial species inhabit the same space. Researchers at University of California San Diego have discovered that when certain microbes pair up, stunning floral patterns emerge.   In a paper published in the a recent issue of eLife, a team...

The Life and Death of Turbulence - Lecture: Nigel Goldenfeld November 21, 2019

Roger Dashen Memorial Lecture November 21, 2019 Garren Auditorium UC La Jolla Campus - 4:00 PM Lecture The Life and Death of Turbulence Nigel Goldenfeld - Dept of Physics University of Illinois, Urbana-Champaign Turbulence is the last great unsolved problem of classical physics. But there is no consensus on what it would mean to actually solve this problem. In this colloquium, I propose that turbulence is most fruitfully regarded as a problem in non-equilibriu...

Borrowing from Astronomy to Rob the Twinkle from Brain Imagery

Neurophysicists make new recording of nerve signals by adapting tools of astronomers For decades, astronomers have solved the problem of removing the “twinkle” from images of stars in the night sky. They use a process called “adaptive optics” (AO) to correct for changes in the density and moisture of air in the atmosphere that scatters the incoming star light. Recently, UC San Diego Professor David Kleinfeld, along with postdoctoral fellow Rui Liu, realized how to adopt this same p...

Researchers Unravel Mechanisms that Control Cell Size

Working with bacteria, a multidisciplinary team at the University of California San Diego has provided new insight into a longstanding question in science: What are the underlying mechanisms that control the size of cells? Nearly five years ago a team led by Suckjoon Jun, a biophysicist at UC San Diego, discovered that cell size is controlled by a fundamental process known as “the adder,” a function that guides cells to grow by a fixed added size from birth to division. Yet mysteries remained about th...

Scientists Confirm Events that Occurred One Second after the Big Bang

One second after the Big Bang 13.8 billion years ago an abundance of invisible subatomic particles was released from the hot plasma that filled the universe, forming what scientists call the cosmic neutrino background. These neutrinos pass through great distances in matter without being impacted, yet they influence the enormous distances between galaxies. Now a team of international scientists, including researchers from UC San Diego, has produced a measurement that adds to the understanding of the universe within a second of its creation. T...
