Assume v. Presume

[EEPhil]

Are any of them still relevant?

I doubt it, they were hardly relevant at the time!

It's blatant discrimination (a postcode lottery) with the lucky ones being in Wales, Northern Ireland, Scotland,

You could say the same about prescription charges. How we managed, in England, to get them free from 60 I don't know - but am grateful! Fortunately I wasn't diagnosed (hypertension) until I was 60, otherwise I'd have needed a season ticket! Four items at £9.90 per item every 28 days = a lot (£514.80/year vs £114.50-ST vs free-over 60).

The micro- prefix is only generally needed for capacitors,

Or inductors. Microhenries are common at frequencies in the shortwave region and above.

Possibly conductance, if you are that way inclined.
