After some soul-searching I figured there's no way to avoid that I come up with a video myself. Ideally one that a) leaves plenty of space to do better, and that b) makes it very clear I'm not the person to record or edit any video. So here it is:
There is nothing happening in this video, except me standing there and talking, so don't expect much action.
As you can easily see, I still haven't figured out how to turn off the automatic brightness adjustment. That's because it's not my video camera, I have no manual, and the menu description is cryptic at the best.
While I'm at it, I want to draw your attention to this nice blog run by Claire Thomas, physics graduate student at UC Berkeley, who collects videos of researchers explaining why they do what they do. So, get inspired, turn on your camera and tell us what you're working on!
