re-learning maths

Surely in leeds there are enough hairy toed morlocks walking around that
you can count on their bare feet.

 

It was.

The only stuff I can properly remember is GCSE Electronics, because I've
applied it.

 

Yeah but that only takes me to 16

 

Any particular branch of mathematics?

 

Is sort of the right answer.

I have continued to do some sums I learned at school and learned some
new skills as well. Given that new skills are always an extension of
old stuff it hasn't been that hard. The key I think, is to have real
world reason enough to want to keep up the effort to do it and a bit of
revision before you tackle the new stuff.

 

I've got 'O'level Physics twice (only an 'O' level pass at 'A' level).
It was always the fancy maths that was my downfall. Didn't stop me
getting into the IoA in the end though. A lot of acoustics calculations
can be done on the back of an envelope using "rule of thumb", and those
that can't are fairly easily set up in Excel with the aid of textbook
and a rudimentary understanding of BODMAS.

It's much the same with languages.
I used to be fairly fluent in a couple, not now!

 

This is exactly what I've just started. I took a maths book on holiday
just before Xmas. Admittedly my progress has been both slow and
erratic, but at least I'm doing it. Not helped in any way by a new
Xbox game, a small stack of new books and my inherent laziness though.

 

I was expecting some to come back with "branch of mathematics" ...
.....it must be twignomatree.

Every now and then I get my pencil out and do some equations for the fun of
it but I've forgotten loads.

 

Yebbut could you derive it via completing the square?

 

Give it time. It is winter so most of ukrm don't think as fast this
time of year but now you have given them a hint one or to might be able
to root something out from one of their sub brains, probably the warm
one at the base of their spine.

 

Nope. TBH the whole area of equations == graphs left me cold, and
still does. One of the stats our users (statisticians) use is "area
under the curve" and I never understand why they don't want to simply
add up the values...

This is a Good Thing. Maths is a young persons game so get used to it
granddad. Anyway, if there is something specific that you need to know,
you will pick it up with willpower, experience and osmosis. Don't panic.

 

if I can't find anything online to suit, I may well take you up on
that - cheers.

 

Equations are pretty much the best bit for me as they're all about
solving problems. Stats on the other hand is the devil's work - to me
it's all hand waving and black magic. The only bit that interested me
was Student's t-test, or rather the origin of the test which really is
rooted in a bit of black magic if the rumours are true.

Although you could describe finding the area under a curve as adding
up all the values, in many cases (I think) it is pretty much
impossible to add up *all* of the values without using integration.

 

But in the case of clinical trial data, where you start by having all
the actual data values, why go through all the effort of changing them
into an equation and feeding it into some arcane black-box
calculation?

I have the same at O&A level plus some stuff for an electronics BTEC.

I have the same lapses in memory.

Fortunately my lad has no interest in maths/science stuff for his A
level/university aspirations, as I don't wish to relearn the theory &
methodology.
