From outside the US, the glaring problem with "prosperity gospel" thinking seems to be that the unfortunate (the "losers") are blamed for their misfortune. It seems like a case of selfish individualism being supported by

Usual official advice is not to start drinking purely for sake of health benefits -- they are outweighed by risks at any level of consumption.

Another angle is: do you want your kid's first encounter with the idea of Ukraine or Slovenia to be a disparaging/pejorative stereotype? Even if it was a real factual representation it might encourage the kid to pick up or repeat

One reason why GA hasn't caught fire in graphics is the complexity: for many tasks it is slower that the old way. AFAIK.

Aside from unfortunate aesthetic, and puzzling practical issues (like no attempt to replicate TeX's math support), something about the overall tone of the docs and Cozens' web presence would discourage me from making an investment

Cartridge is easily big enough to contain a camera (see phone tech) so I'm not sure it makes much sense to make a system which separates the two. A digital photo frame with built-in camera seems more plausible, cute as it is to emulate

Hmm, really it was more like a geometric progression. David Gelernter has commented on the lack of familiarity art/architectural historians have with terminology like "recursive" or "self-similar" (I prefer the latt

Easy and instant recognition is often a sign of triviality, accepted. But, like in written poetry, a command of the pop idiom is not enough to create a hit: there's got to be something convincing (and generally hard-to-pin-down) about

Come on, art is not measured by how complex or technically intricate it is. It's a matter of feeling and atmosphere. Techno is a sensibility and a culture, not a celebration of individual masterpieces by "geniuses".

Still, culture operates on a "hubs and authorities" basis -- there are people whose job it is to be hubs (curators, publishers, music programmers and promoters) and people who become known for their genius ("authorities"

Yes, as has been discussed here before, thinking in terms of proofs is a huge part of mathematical maturity, as required by university undergraduate mathematics. See "The Book of Proof" etc.

Though it can be thought of as varying with latitude in this case, it's much more complicated than that for eclipses in general. So latitude can work as a pragmatic proxy variable in this case but not for all eclipses: e.g. http:&#x2F
