Ummm ... maths is fun!

Here's my favourite formula derivation:

Women require time and money
(w = t x m)

But time is money
(t=m:   therefore w= m x m: w = m²)

We also know that money is the root of all evil
(m = sqrt(e): m²=e)

therefore
(w=e)
Women are evil

See what I mean. How is that fun?

2 x wX (x-2y) = Z bananas    oh my sides! hilarious!

Does look like the Indians have that one.

At school quadratic equations were a mystery. Once I started to encounter them at work it turned out I was quite good with them. I still think that all school taught me was how to teach myself stuff! Which, to be fair, is a skill not to be sneezed at.

Somewhat off topic, but since the Tiny Goblin is taking his Maths national 5, I've rediscovered some old school maths tricks.
My own school maths was a mixture of aceing things that could be visualised, and being utterly bewildered by simple things that were explained in a non-visual style.
A great example of a befuddler was Imaginary numbers - "What's the square root of -1".
I tended to hit around 80% in exams, because about 4 / 5ths of the curriculum lent itself to visualisation.

Anyway, there's a recent video by Lindybeige on music teachers.
His simple concept applies well to the teaching of many other skills.

Maths are not fun but Math is fun (to resurrect a oft recurring theme).

I actually, really enjoyed MATHS .....Sorry, Bill
I got a decent grade at that.

And what did I end up doing ?.........Pushing epoxy putty around.

I was fair at Calculuss (perhaps you know the subject as Fluxionss) and Differential Equationss. .

Stop bullying people from the USS. Some of them are quite pleasant...no, really, you'd be surprised....some of my best friends....

Mrs Westie says if she ever meets you, you better duck.... 

What constitutes a "better duck"? Longer bill? Greater wingspan? Cherry sauce? A bright blue sailor suit?

[d_Guy]

A better duck is one in which one achieves not being hit in the head.

I remember doing logarithms half a century ago.....Can't imagine those are still used for anything. I can only vaguely remember how to use them.

What about slide rules ?...I don't suppose they even exist, nowadays.

Why, when your mobile has a more powerful calculator installef than NASA had for the entire Apollo programme!


We have some on display in the museum...

Not used as they were in school Maths (Adding / Subtracting in place of long multiplication division), however they remain in many more advanced guises.

Examples:
1. Measurement over vast ranges: Richter or Decibel scales.
2. Big/small numbers (Scientific notation beloved of Professor Brian Cox and friends) "That has 32 zeroes after it".
3. Compound interest / growth.
4. Graphing trends where growth is exponential.
5. Atomic decay.
6. In everyday language: "Eight digit transfer fee".

Techno Logie  has progressed SO far.....(Too far ?)

I believe the first 'computer' that Von & I owned....(It was just a word processor, in truth)....Had more processing power than Voyager 1. The then height of computer sophistication.
The main frame computer, that Von worked 'with', decades ago, took up a room the size of two tennis courts....and was eventually sold for scrap....after originally costing more than a million quid....THEN !

This piece of poop that I'm typing on, makes THAT 'computer' look like a giant abacus.

First computer I used had programs typed onto punch cards.

They had to be given to computer services and they ran the program. Output was on big sheets of fanfold paper.
