refractin’ back atcha

A few of my Povray scenes include objects with negative indices of refraction; I’ve said of this one that three-quarters of it cannot exist in the real world. Now I read in The Economist that, because a negative-refractive slab could make a “perfect lens” (for obscure reasons), there’s an active effort on to create such a chimera; indeed the effect has been demonstrated but only with microwaves.

Plutinos, Twotinos, Cubewanos

John Baez gives (among other things) a handy summary of transneptunian objects.

how do you tell racism from diversity?

I’m watching a collection of Tom and Jerry cartoons, made by Joseph Barbera and William Hanna, who were later known for the much cruder animation of The Flintstones.

I’m puzzled by the opening disclaimer in which Whoopi Goldberg explains that while the ethnic stereotypes that appear in some early cartoons are wicked it would be wrong to falsify history by cutting them out. The sin, apparently, is that Tom’s owner, a woman of color known as Mammy Two Shoes (though her name is never mentioned in the toons, nor is her face shown), speaks in nonstandard grammar; she has no other stereotyped qualities that I can detect.

Whoopi makes the same disclaimer in a Looney Tunes collection, and there it makes more sense; I’ve had occasion to cringe at some early ones, though I have not seen such moments in this collection (yet).

possibly not one of my brightest ideas ever

If my new printer’s resolution is 1200 dots/inch, then a sheet of gringo-standard letter paper with half-inch margins can take an image of 9000 by 12000 pixels. As a test, therefore, I rendered one of my most complex Povray images at that size. It took 182 hours.

Now if I can find a program that will open an image that big . . . .

a catalog of what ain’t

Whatever it is (or isn’t), someone has made a list of it.

Here’s one that interests me a bit: once upon a time I started a (mental) list of persons ineligible who have portrayed a President of the United States, such as Peter Sellers (as Muffley) and Anthony Hopkins (as Nixon). (Found from a related page cited by the muted horn.)

creepy

Now class, who can tell us why this advertisement (The Economist, Nov.12, p.67) bugs me?

When you meet the men and women who serve America in the military and government, you find the strength and character of this nation. . . .
