I am a theoretical physicist at University of California, Berkeley. Last month, I attended a very interesting conference organized by Foundamental Questions Institute (FQXi) in Puerto Rico, and presented a talk about making predictions in cosmology, especially in the eternally inflating multiverse. I very much enjoyed discussions with people at the conference, where I was invited [...]
The Institute for Quantum Information and Matter (IQIM) at Caltech invites applications for postdoctoral scholar positions in quantum science. IQIM investigators span Caltech’s departments of physics, applied physics, and computer science, and are interested in a wide spectrum of both experimental and theoretical research topics. These topics include, but are not limited to, quantum information science, [...]
Science evolves on Facebook. On Facebook last fall, I posted about statistical mechanics. Statistical mechanics is the physics of hordes of particles. Hordes of molecules, for example, form the stench seeping from a clogged toilet. Hordes change in certain ways but not in the reverse ways, suggesting time points in a direction. Once a stink [...]
Transforming the STEM Pipeline into a River The traditional metaphor of the “leaky pipeline” tracks the number of students entering the educational system and emphasizes points at which women and minority students leave the system. IQIM is working to increase diversity on our campus and more broadly in STEM by encouraging a [...]

This year marks the 50th anniversary of my first publication. In 1964, when we were eleven-year-old fifth graders, my best friend Mace Rosenstein and I launched The Pres-stein Gazette, a not-for-profit monthly. Though the first issue sold well, the second issue never appeared. Front page of the inaugural issue of the Pres-stein Gazette. Faded [...]
Last Friday the 13th was a lucky day for those who love physics --- The online html version of Volume 1 of the Feynman Lectures on Physics (FLP) was released! Now anyone with Internet access and a web browser can enjoy these unique lectures for free. They look beautiful. Mike Gottlieb at Caltech on [...]
The elementary school I attended hosted an annual book fair, and every year I went with my mother to browse. I would check out the sports books first, to see whether there were any books about baseball I had not already read (typically, no). There was also a small table of science books, and in [...]
Five years ago, I was staring out one of the few windowed cubicles in a cluttered office full of overambitious salespeople willing to throw their own father under a bus, if it meant a couple more dollars in commission and maybe a few more brownie points from the sweaty, beer-bellied sales manager. What was going [...]
Public Outreach In addition to educating a new generation of students and scientists, IQIM strives to engage the public’s fascination with the mysteries of the quantum realm. Follow our blog Quantum Frontiers with regular posts by IQIM graduate students, faculty, postdocs, and a few guest authors. Topics include discussion of recent breakthroughs in science, [...]
