Carver Mead is a pioneer of modern microelectronics. He proposed a new methodology, very large-scale integration (VLSI), that would make it possible for creating millions or billions of transistors on a single integrated circuit (microchip). His research investigated techniques for VLSI, designing and creating high-complexity microchips. This design process has advanced electronic technologies and transformed the lives of most of the people inhabiting our planet. Mead also paved the way to VLSI design automation and facilitating the revolutionary development of today's VLSI-based electronics a ..read more

The American Physical Society has designated UC San Diego’s Mayer Hall as a historic site in recognition of research conducted by physicists Walter Kohn and Lu Jeu Sham on density functional theory. Their development of the "Kohn-Sham equation" inside Mayer Hall became the foundation for the computation of the material properties of electrons and nuclei. Understanding the electronic properties of complex systems is essential to the design and engineering of new materials and drugs. Kohn and Pierre Hohenberg on sabbatical in Paris developed a theorem for the electron ground state energy to depe ..read more

The International System of Units (the SI), the modern metric system, has recently undergone its most revolutionary change since its origins during the French Revolution. The nature of this revolution is that all of the base units of the SI are now defined by fixing values of natural constants. Our measurement system is now, both philosophically and practically, strongly quantum. Nobel Prize recipient William Phillips, Ph.D., a Distinguished University and College Park Professor of Physics at the University of Maryland, talks about why this reform was needed and how it is done. Series: "UC Ber ..read more

Julio Barreiro Guerrero grew up in a public housing project in Acapulco de Juarez. Inspired by a junior high teacher, he found his passion for science. Through hard work and focus he found himself the recipient of scholarships that opened up a world of opportunity in physics. Today, he runs a lab at UC San Diego focused on quantum science and technology. He shares his story and a message of inspiration for young scholars starting on their academic journeys.

Proteins are nature’s machines, performing tasks from transforming sunlight into useable energy to binding oxygen for transport through the body. These functions depend on structural arrangement of atoms within the protein, which was, until recently, only possible to measure statistically, in easily crystallized samples via conventional X-ray diffraction. In the past decade, X-ray Free Electron Lasers (XFELs), a new type of X-ray source, have begun to come online. Using ultra-bright, ultrafast X-ray pulses of the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory, t ..read more

Particle accelerators have been revolutionizing discoveries in science, medicine, industry and national security for over a century. An estimated 30,000 particle accelerators are currently active around the world. In these machines, electromagnetic fields accelerate charged particles, such as electrons, protons, ions or positrons to velocities nearing the speed of light. Although their scientific appeal will remain evident for many decades, one limitation of the current generation of particle accelerators is their tremendous size, typically a mile long, and cost, which often limits access to t ..read more

Do complex systems exhibit fundamental properties? This talk looks at tradeoffs between robustness and fragility that occur in biological, ecological, and technological systems that are driven by design, evolution, or other sorting processes to high-performance states which are also tolerant to uncertainty in the environment and components.
