FEEDBACK

Ranking internet search results according to how well they reflect "facts the web unanimously agrees on" (28 February, p 24)? What could possibly go wrong? Adrian Ellis wrote to ask about something the web is unanimous on: that glass is really a very thick liquid (14 March, p 54). Well before the ink was dry on his letter, a colleague asked a FWSE (famous web search engine) about this. It shot back: "Antique windowpanes are thicker at the bottom, because glass has flowed to the bottom over time... Glass is a supercooled liquid. Glass is a liquid that flows very slowly."
