Donation 24 yesterday, first one where I've been able to snaffle a "My Dad Gave Blood" sticker non-ironically.
Didn't even have to plan it in advance, an ad hoc day into the office that I could tag the appointment on to. I remember when you could book appointments online, but not on-the-day, and it's really a good improvement. -

Depends on the riding you do and the chainring you choose, I don't think it would be that different to using a 1x on a touring bike. Reliability wise, 8spd is beefy but you'll have some huge jumps.
We have an 11-34 8spd cassette that is spaced to be usable across the range. The 11-34 used to jump 26 to 34 so I cobbled one together from a 11-34 and 11-32 (jumps 28-32). (See here.) They seem to sell this arrangement now which is useful https://bike.shimano.com/en-EU/product/component/claris-r2000/CS-HG50-8.html -
If they're that late on issuing the final bill they should give you an automatic 'standard of service' credit.

The manual says that for a 230 V installation on a single phase (what would come from a plug) it will draw up to 32 A. It doesn't look like it has an option to limit the total power draw as some units do, so to get the most from it you would want to run a 32 A radial circuit back to the CU.
the previous oven wasnt on a plug but was hooked in with the induction hob directly
This sounds like a Not Good set up, it's good that this has been found. IANAE

The "Required Fuse" entry on the datasheet is what you need to look at. That's saying 16 A, and so you will need that wired in directly. There are definitely ovens made that go into 13A sockets (they'll be sold with a plug on the flex, rather than a bare end) but you're right that they probably won't do pyrolytic cleaning.

I had a friend who did do it in Y1 UG, I'm not suggesting you didn't either. It threw me when they mentioned it, then I realised what they meant (the volume element) and it made sense again. I think it's down to who teaches that particular topic as to whether they get diverted by the Jacobian.
Personally, if I was teaching it and was just going to use the Jacobian determinant for the volume element then I wouldn't introduce the terminology. I don't think it would add depth, just jargon and confusion. -
As an aside for anyone who enjoys a bit of integration, I have really been enjoying the challenge of Integral of the day recently.
Ooo, now that looks fun! #nerd

I went through my entire physics undergrad without (explicitly) being introduced to the Jacobian, only to find I knew it as a different thing. I'd say its determinant naturally comes up with the introduction of multiple integrals and then the full Jacobian matrixis maybe introduced alongside vector calculus.
FWIW we don't explicitly cover it as part of our Y1 or Y2 maths courses in a STEM UG programme. Definitely not an A-level topic, even at further maths.
Not done it, but I live just off it. If you want a hot shower part way thru (near Sevenoaks) then dm me. I'm WFH those days so don't mind the time.
