Making these videos is way easier than doing my chores.

Becoming Screen Literate
Kevin Kelly in The New York Times

I am not screen-literate. My first reaction to this article was to think the barrier to becoming screen-literate was still rather high – there’s a learning curve associated with using the video technology Kelly is writing about. Not all that many people are skilled at video editing, but nearly everyone can write. But then I realized that not that many people put much effort into becoming “screen literate”, whereas everyone in America is forced to write extensively in school for many years.

So what are the consequences of “visualcy” dominating over literacy? Is it a Brave-New-World-esque degeneration into overstimulation, short attention spans, and a intellectual hedonism, or a improvement in the efficiency with which we can absorb, process, and create new information that leads to higher levels of creativity, collaboration, productivity, and better life?

Garrett Lisi’s Exceptional Approach to Everything

They forgot to draw his hair. Also, this story would be more inspiring if Lisi’s work were broadly considered by other physicists to be a meaningful step forward in theoretical physics. His work has gotten far more media attention than attention from his colleagues.

Finally, a good reason to cut yourself.

Cool Things the Greeks Did in Astronomy
Dot Physics

How are you supposed to measure the distance to the Sun? Turns out it’s more than a million hot dogs end to end. Of course, hot dogs shrink a little as you cook them by putting them closer to the sun, but still, it’s a lot. How did they count that high anyway?

Self Control and the Prefrontal Cortex John Lehrer at The Frontal Cortex

Summarizes some research that indicates people only have a certain amount of willpower to ration out over the day. My first reaction to reading this article was to think, “yeah, but that’s only for weak people, not me.” My next reaction was to resist the temptation to check my email too frequently. My third reaction was to slaughter eight cats in a murderous frenzy, then to sit forlornly surveying the carnage I had wrought and wonder if this cycle would ever end.

Scott Belcastro’s Lonely Searching from Erratic Phenomena

I’ll admit I don’t know much about art, but I can tell when something looks cool. I saw how similar the paintings were, and felt surprised at first that people don’t get bored doing the same sort of thing over and over. But then I realized it must be because they’re refining, focusing down, and trying to work out subtleties and understand their subject more fully. Not that I see all the subtleties, exactly, but maybe if you read the text they actually talk about that stuff.

The Gallery of Fluid Motion
Videos of fluids being fluidy. Don’t get too excited, though. Despite what it sounds like, this is not a potty cam.

The Incredible Beauty of Hummingbirds in Flight RJ Evans at Webphemera

Small things can be pretty. They aren’t always pretty, which is sad news for your penis.

Is This The Oldest Eye On Earth? Tom Simonite on New Scientist

“It could be the oldest eye, or even human body part, still functioning or to have ever been in use for so long.” There’s a story for the grandkids.

The Laplace-Runge-Lenz Vector Blake Stacey at Science After the Sunclipse

A clever way to prove that orbits in a $r^{-2}$ potential are conic sections, without solving a complicated differential equation. I’m surprised we didn’t do this in ph1a, although I’m kind of glad we didn’t, because it makes me appreciate it much more now.

### New Problem: The Kepler Exhibit

October 17, 2008

At the Exploratorium in San Francisco, you can play with this exhibit:

What should the height profile of the bowl be so that balls that roll without slipping (or, so that blocks sliding without friction) would reproduce 2-D Kepler orbits when viewed in projection from above?
