The temptation to edit a Wikipedia page to make it correct, but would require nested parentheses, the other editors might think I just pasted in a page of lisp code.

You know someone is setting up for some serious physics when the 50mm thick lead wall comes out to play.

@Dtl One of these days there will be a particle that goes around corners and then everyone will be in trouble. Meanwhile I’d be worrying about radiation reflecting back off the far wall to come up behind the researcher πŸ˜‚

@Dtl I'd like to call it Shield-o-tron please.

Taking this out of a comment and into a thread of its own.

Is my heavy water still heavy? I have a bottle of 99% D2O, and it's hygroscopic, I don't know the history of it before I got it. It's about half full. It might have sucked in a lot of normal water from the air.

@Dtl You could make an icecube and see if it sinks in water. In theory Deuterium is stable contrary to Tritium. If it was 99% pure ten years ago and the lid was tight, it still is 99% now.

@Dtl that’s a blast from the past. Thanks for posting.

@Dtl I was going to say that you're venturing dangerously close to philosophy with those kinds of questions.

I love that if anyone asks "what geeky things can I do in London?" There are lots of replies saying Novelty Automation.

@Dtl Oh, that's fun. Been ages since I've been there, but was worth a visit.

Every warning label is a story someone tells somewhere.

@Dtl That's excellent. If there was anything that shouldn't be used as a handle in a circuit board, i don't think you could choose anything worse than a cap!
