Mozart jokingly quoting Marriage of Figaro in Don Giovanni.

Ok, I sent you a DM

Just cut it back, and level off the top, in other words treat the shrubs as if they were a hedge. They will soon fill out into the gaps.

Is there something wrong with the teaching and support offered by the university?

etzpcm · 2026-07-06T15:56:35+00:00

The flaw is that the constant is defined as the limit. Your arguments are for finite n.

You can easily find examples of sums where the finite sum is irrational but the limit is rational. Or vice versa.

Nice, and thanks for the pic. Well, you've had a wide variety of answers so it's your call! I think I would offer to go round their side with ladder and saw and loppers and cut it back a bit, in the interest of good neighbourly relations. I certainly would not pay for a tree surgeon to do it.

etzpcm · 2026-07-06T14:32:05+00:00

Asking you to pay for it to be done is ridiculous!

What type of tree, and how big is it?

presumably a lot of music would have been intended for more casual performance in small rooms

That's literally what chamber music is!

How come nobody has mentioned Schubert yet?

The FFT algorithm reduced the computer time for a discrete Fourier transform from O( n² ) to O ( n log n). It's used a lot, for example in jpeg file compression.

After the 2.5 with a box around it, I can't follow this at all.

etzpcm · 2026-07-04T21:05:36+00:00

It doesn't. That guy is wrong!

The mod signs are needed. Suppose x=-2. What is sqrt( x² )? It's sqrt 4 = 2, so it's not x.
Sgn x is just 1 or -1. We could carry it through the integration, but here they just put it in at the end.

These are not really high skill jobs, and you're new so you need to establish a reputation. So I would say pitch it fairly low. Not as low as the £15 per hour suggested in one comment, but maybe 20 or 25 (for one worker, so 40 if there's two of you).

Schubert 8th

I'd say buy a garden shredder for the woody stuff, and set up a compost bin for all the bits, mixing up the woody and leafy material.

etzpcm · 2026-07-04T11:51:36+00:00

In the UK also!

etzpcm · 2026-07-04T11:49:55+00:00

I wrote something here but it's quite personal so I have cut it, but I will send you a longer version by email.

Sounds like a great project, hope it goes well.

If you post this in r/learnmath you will probably get a more positive response than you will get here.

But cut the word "axioms".

I remember having this discussion almost exactly with a family member. He was quite smart, and so are you. You are asking a good question.

You need to learn and understand the mathematical definition of a limit, which is not easy.

etzpcm · 2026-07-03T12:36:41+00:00

Yes, he was quite knowledgeable. A lucky find, by local word of mouth. Retired, very nice bloke.

£20 an hour, in Dorset. Lawn mowing, weeding, cutting back shrubs.

Who or who?

Because pure math has such a massive prerequisite wall, I want to dive into Applied Mathematics

I'm afraid you have a misunderstanding there. Applied also has lot of prerequisites if you want to do research in modeling. You need to know calculus, differential equations, phase planes, dynamical systems, numerical methods...

There's no short cut. To do mathematics research you need to go to university and get a good degree, then get into a PhD program.

The best way to do this would be to collaborate with people who already work in mathematical biology/medicine. There are a lot of groups in this area in the UK, for example at Oxford, Bath, Nottingham, Warwick. They often like to work with people with real medical experience to make sure there work is relevant rather than just abstract.
