@Printdevil @Fasgadh That's the one! Don't know exactly what the study was, but I was being monitored while seeing very brief snapshots of facial expressions. Hey, paid for a night out!

@13pt8plus I recently spent a weekend with friends I first met through stand-up comedy in the early 2000s.

That gag, and specifically the dry delivery, would have got a handshake from all of them.

@Printdevil @Fasgadh I volunteered as a parapsychology subject at uni in the 1990s, it was a thing in Edinburgh! All for it, if the cost to benefit ratio works. But that does seem to have slipped over the years...

@Fasgadh I'm in the sweet spot, technician rather than a teacher, and one who enjoys student interaction.

(Insert GIF pronunciation gag at your leisure.)

Me, walking into lab where teacher and 6th years (~17/18yrs) are talking. They stop.

Teacher: "OK, Geoff, do YOU believe in ghosts?"

Me: "Erm...I believe people *experience* them..."

Teacher: "But what about our energy, what makes us 'us'? Where does that go?"

Me: "What units are you measuring this energy in? How are you measuring it?"

Student, deadpan: "Ghost energy is obviously measured in Ghouls."

No notes, perfect, told student they should write next Ghostbusters film.

@alexisbushnell The other temptation is to recycle it into a pyrograph for burning patterns into wood. Again, not a good idea unless you're a qualified high voltage electrician. Of all reported [edit: US] injuries there's a 71% mortality rate.

@alexisbushnell I'm all for repair, reuse, maximise usage etc, and take great pride in fixing a lot of broken electricals/electronics. But the very specific hazard of the kilovolts transformer in microwaves over-rides that for me, worst case scenario is a corroded connection breaks and makes the casing live. Not 240V, but 3,000V. At that point touching the microwave while it's running has a good chance of killing you.

@alexisbushnell That'll provide surfaces for bacterial growth to an extent. I wouldn't worry too much about microwave leakage, you'd need an obvious hole in the casing for that. But it does make me twitchy in terms of electrical safety. Given that you can get a new one for £40 I'd recommend that.

@alexisbushnell If I had one at work (a school setting) I'd bin it and buy a new one, given the cost v safety ratio. At home, at my own risk, it would depend on where the rust was, how much etc.
Main risk is losing the Earth connection to the casing, the internal transformer works at lethally high voltages (a few kV) with easily enough current to kill. The Earth connection will blow the fuse if a fault makes the casing live. Rust on the outside may also mean rust on the inside.

@mcc One of my all time favourite games, the early thing with the sunbeam in the hallway is genius.

@HighlandLawyer @dillyd A friend has coeliac disease. Clinically diagnosed, rather than an intolerance to gluten. We ate together in a cafe where he asked for gluten free and they specifically asked how sensitive he was, and had some stuff intentionally made in a gluten-free bit of the kitchen.

All credit to "Deli In The Square" in Strathpeffer. Also awesome sandwiches.

Hivemind! Useful physics for a veterinary student to do at undergrad level? (For a vet student who wants to do more physics at undergrad...)
I'm thinking imaging/radiography/ultrasound stuff, biomechanics/ergonomics. Any other ideas?
