Yes - you've reminded me of my undergraduate place interview at Imperial College. "Sketch the curve for the function sin(x)/x" I was asked, not having encountered it before. Of course the natural place to start is at x = 0... (anyway I was talked through it using L'Hopital's rule an a plausible curve ensued. I can't have muffed that interview too badly since they offered me place - which I turned down and went to Bangor instead. One of the Profs there (Alwyn Owens) had a saying "Education is a process of diminishing deception", simply meaning that simplifications had to be introduced in order to get started. I also remember one of the school physics teachers saying something similar: "in the 2nd form we tell you that light always travels in straight lines; later on, when we study diffraction, we admit we were lying." Fair enough. Unlike our resident kook, I don't see that any subject is debased by being introduced in a simplified form to people at an earlier age.
Agreed.
That's always a pity. We had one useless teacher in the maths department (whom I managed to avoid getting). The others were very inspiring.
I could not agree more. "It is virtuous to be able to analyse a circuit in great detail. It is more virtuous to be able recognise when no such analysis is necessary" - the great Peter Baxandall, writing in Wireless World.
Yes, it just refers to presence of a larger heat exchanger surface area. Most manufacturer's data sheets quote an area in m^2.
True, but "I've done good" never used to be acceptable in speech. It's not idiom, it's just wrong, IMO.
Ooh, I loathe that expression "can't be arsed". It's of quite recent origin; where did it come from? And what's wrong with "can't be bothered?"
Ebso farkin' lootly, as HRHTPOW might have put it.
A very good thing. I turned down IC, Nottingham and Newcastle.
I remember him well, and that saying, but I don't think he invented it.
He did, however, have a remarkable sense of hearing and was able to detect an individual creeping late into the back of a lecture theatre of 100 students while writing on the board. He had a photographic memory as well, because he could identify the individual (wasn't always the same one) and tell them to leave.
Were you there before or after the counterweight incident?
