It's a style or a sensibility in other words. Gorgeous rawness—not just accidental rawness. Don't ever try to convince an architect of that, though.

You're assuming a symmetry between sight and touch that is unlikely to hold completely. There is an interesting, if largely anecdotal, paper from the 60s. There may be more recent work. http://www.richardgregory.org/pap

This was for Zeus, the high-performance web server guys. So I guess it was a thing for them to optimize in general: a USP. If you specify that the files are way too big to fit in memory, well, that's a different story.

According to that page "Terra preta soils are found mainly in the Brazilian Amazon, where Sombroek et al.[18] estimate that they cover at least 0.1 to 0.3%, or 6,300 to 18,900 square kilometres (2,400 to 7,300 sq mi) of low forested Am

Yes, but this kind of HTML authoring is often accompanied by a puritanical dedication to "structural markup". It is often evidence of quite an opinionated, reductive, approach to the web, for better or worse.

Quaternions are an extension of the idea of complex numbers. Complex numbers have a real and an imaginary part, while quaternions have a real part and multiple imaginary parts (3). So the basic idea is that these richer types of number, whe
