Since even a phone has enough processing power to make Stockfish play better than a super-GM, the Faraday cage isn't enough to prevent, say, someone tapping the position into a computer on their person and feeling for some sort of vibration[1] in response. It takes very little information to represent a position, and commentators have pointed out that the minimum amount of information required to produce a decisive advantage is 1 bit ("A winning move exists").
The adjournments in The Queen's Gambit were rendered obsolete after chess engines became strong enough to be useful in analysis. The last year that they were permitted was 1996.
Match play at the World Championship (where the two players play each other repeatedly for many games) involves a ton of inter-game coaching and work as each player's team goes over what went well, what went wrong, and how the next game should be approached.

We don't make enough pasta at a time to use a full jar, (and in fact will usually use a small fraction of the jar) so I write the date that I opened the jar on the lid to plan its use a little better. "Hey, better find a use for this sauce, it's going to go bad eventually."
Inversely, I've also seen promotions where the gallon is heavily featured in the ads, and they're selling the half gallon for full price. Neat, you're paying extra to get less milk!
Grade school for me - teachers would say "8.5x11" instead of "letter size" or even just "printer paper." I don't know why they did it, and I assume it's for the same reason that I say it too. It's probably what their teachers said to them!
