Random question. Historically, why have Lead and Gold been so closely linked? Why did alchemist focus on turning lead into gold (and not start with iron, or a rock like quartz)? Is it just because they're two heavy soft metals?

> He stood on the shoulders of Persian, Greek, Indian, and Chinese precursors, while Renaissance inventors, in turn, stood on his.

This is the first time in my life where a western outlet doesn't try and obfuscate the fact that many of the "discoveries" made by europeans in the the renaissance period have taken inspiration from the close to 800 years of Islamic scientific research (who themselves never failed to credit their predecessors).

Typically, when you study the history of science in the west, it starts at ancient greece (who have no contemporaries) then there's a massive blackout of 800 years and poof ! The "light" is magically turned on.

Fair play to the author for not being biased.

So, as someone who has lived in regions with pretty severe internet censorship in the past and built circumvention software back in the day, I've always pondered the idea of whether one could build a fax-based thing like this for browsing the web. Kind of as like a "last resort" system.^

Could have a form that you fax in with, like a URL and session info (cookies and stuff), and then it faxes back the page, and you can circle stuff and fax the page back to interact and "click on" things.

Plus, since computers can ingest faxes, you wouldn't need to waste paper printing everything out, and could just do everything digitally. But you still had the option to use paper and a fax machine if you really need to.

^: Yes, I know faxes are unencrypted and phone lines can be tapped. But I've always found the idea intriguing. Plus having some emergency point-to-point communication to bootstrap things like key exchange could still be neat.
