It's really fun to play with black and white photography using various kinds of color filters and see how different you can get the same scene to appear. (Also fun to play with a polarizing filter.)

Maybe to be more precise, conformal projections like the transverse Mercator projection and the conformal conic projection were adopted by militaries after WWI, and the UTM system per se was created during WWII.

For a low-discrepancy sequence you are usually trying to generate one point at a time, up to some arbitrary number. Here the goal is to generate (roughly) a specific number of points that fill a whole region. So you probably could figure ou

That's not at all about fine detail, but is about relative amounts of absorption/reflection of the light between skin vs. vein. See https://en.wikipedia.org/wiki/Metamerism_(color)

I'd recommend reading the Federalist Papers. A large number of them are more or less explicit warnings that Trump-style actions and attitudes should not be tolerated, and explanations about how they should be prevented and countered. T

The so-called "Tea Party" was not a "populist movement". It was a billionaire-funded (notably by the Koch brothers, but also by fossil fuel and tobacco companies) astroturf operation.

Spaced en dashes – like this – are a correct and accepted typographical choice. Whether to use spaced en dashes or (spaced or unspaced) em dashes is a matter of taste or local convention, and varies from one publication to another. Other th
