Isn't it, in the end, just a notational issue? Quaternions are unit bivectors. Up to a slightly annoying sign change, quaternions which are noted as i, j and k correspond to bivectors jk, ki and ij, don't they? There should be a

We were talking about wilderness. Biosphere 2 is about way more than that, as it was a completely sealed environment (it had to produce its own oxygen, for a start).

It seems to me that the opposite assessment requires more justification. Ever since Neolithic, mankind has been domesticating most if not all species it consumed. And we've been deforesting like crazy. We're not hunter gatherer

Notice that such hedonistic trap has existed before, and still exists nowadays. Wise men have always been aware of the risks related to endless and effortless satisfaction. Even if there is no obvious adverse effect, they were pointing ou

Not an expert, but as I understand it most ground is sedimentary rock. It accumulates slowly with time, with things like dust, organic dead matter and yes, part of it comes from carbon sequestration.

I hate this kind of articles. I've clicked to read about some new, exciting scientific/tech discovery, and the first paragraphs I have to read have no relation whatsoever to what I was expecting. Those paragraphs look like an at

I actually was expecting a reference to bitcoin in the article, as this stone money was talked about on bitcoin forums as early as 2011 IIRC. It was considered quite a good analog.

Looking at software that uses Qt[1], I'd say I'll be impressed once they have compiled one of them, say for instance Stellarium, to Wasm. It'd be great to see how a full software, not just a toy demo, behaves in webassembly.
