If quantum computers, femtometer motions or laser alligators weren't enough, let's throw in fractionalized electrons, topological surfaces and strings that go to the end of time. To be honest, the idea that an electron can't be split hadn't even occurred to me before my conversation with Gil [...]

I often get suggestions for comics I should draw, which I welcome because A) I like to think of PHD Comics as a global collaborative effort and B) after 17 years, I'm almost out of ideas. This particular suggestion came from Chen-Lung [...]
[youtube=http://www.youtube.com/watch?v=pktWhH6m_DM?vq=hd720&rel=0&showinfo=0] by Jorge Cham What does it mean for something to be Quantum? I have to confess, I don't know. My Ph.D was in Robotics and Kinematics, so my neurons are deeply trained to think in terms of classical dynamics. I asked my siblings (two engineers and one architect) what comes to mind for them [...]
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 [...]
Sooner or later, most scientists are asked to deliver a public lecture about their research specialties. When successful, lecturing about science to the lay public can give one a feeling of deep satisfaction. But preparing the lecture is a lot of work! Caltech sponsors the Earnest C. Watson lecture series (named after the same Earnest [...]
Opportunities Membership in IQIM is through affiliation with an IQIM faculty member or research group participating in IQIM. IQIM is not a separate department; all members of IQIM are also members of the Physics, Applied Physics, Computer Science, or other associated department. The path to join IQIM is first to join the institute in [...]

Four different types of RA-SHG patterns found by performing local measurements within all of the domains mapped in Fig. 2b. Red lines are fits to the expressions described in the text. The large lobes are shaded pink to emphasize the orientation of each pattern. Schematics of the four degenerate magneto-electric loop-current order configurations are [...]
How many miles per gallon? Thoughts while watching the Olympics … My car gets about 30 miles per gallon of gasoline. Miles per gallon has the dimensions of inverse length squared, and the reciprocal of 30 miles per gallon is roughly the area of a circle whose diameter is 0.3 [...]
