Who's Got the Juice?

Compare the population density of the world, with the nighttime image, which should be some kind of proxy of electric power availability.

In most places, there is a reasonable correlation with high population density giving you bright lights. In some places, like the US, even low population density is noticeably lit up. Now take a peek at Nepal and Bangladesh, just above India. That’s scary to me; all those people living in close proximity without access to modern “conveniences.” Scary in a different way is central China, because one might suspect that electrification is going to be expanding there soon, with all the implications to carbon being dumped into the atmosphere.

“Imagine if the Tea Party Was Black”

Imagine that hundreds of black protesters were to descend upon Washington DC and Northern Virginia, just a few miles from the Capitol and White House, armed with AK-47s, assorted handguns, and ammunition. And imagine that some of these protesters —the black protesters — spoke of the need for political revolution, and possibly even armed conflict in the event that laws they didn’t like were enforced by the government? Would these protester — these black protesters with guns — be seen as brave defenders of the Second Amendment, or would they be viewed by most whites as a danger to the republic? What if they were Arab-Americans? Because, after all, that’s what happened recently when white gun enthusiasts descended upon the nation’s capital, arms in hand, and verbally announced their readiness to make war on the country’s political leaders if the need arose.

The Eyes Have It

Eye Cells as Light Pipes

The retina is at the rear of the eye and includes the light-sensing cells called photoreceptors. But across most of the retina, the photoreceptors are obscured behind three or four coats of additional retinal cells–networked neurons–and a carpet of cellular cables to the brain. Apparently, the retina processes an image by blurring it first. Biologists reference this odd “design” to illustrate that nature’s creations are not all so “intelligent.” Vision scientists have just tried to make sense of how it works as well as it does.
