There is an interesting BBC programme on Algorithms I have just watched on-line, which reminds me of a lot of the course work we did.
Perhaps not interesting to many, but I found the programme fascinating, not least because it is a subject I understand.
(I also like Horizon, even theoretical Physics & Quantum Theory, though less understood !)
The BBC Algorithm programme explained in quite good detail how the Google PageRank algorithm worked, the backbone of Googles Search Engine.
http://pr.efactory.de/e-pagerank-algorithm.shtml
Other algorithms were also explained.
I’ve always had an interest in Mathematics, and still find daily uses for that knowledge, not least of which is designing & using Spreadsheets, for business & personal use.
I wonder if anyone else loves Mathematics, and has put their knowledge to good use ?
One personal example, I can very quickly calculate the change required when purchasing an item for cash, invariably quicker than a shop assistant operating a till can show.
I think mental arithmetic is a skill sadly lacking in many “youngsters” these days, due to technology, and perhaps not being taught it these days ?
Some of my Sixth Form Grammar school classmates, who went onto University, still leave me in awe with some of the discussions we occasionally have, with their superior knowledge of the subject.
As I say, a fascinating programme, well worth watching, it really does stretch your mind.
Algorithms are everywhere…

Not involving me I hasten to add although I do enjoy mental arithmetic.

I haven't really used any of the stuff I learned many many years ago, but still remember being taught how to guestimate during my Higher maths. Still use that facility to this day. Trig now it has always eluded me.

It's certainly taught in primary and there is a mental maths test paper at the end of year 6.

So you don't need to be able to add or multiply to be a mathematician

But I agree that most school kids now are/were taught to use a calculator not how to count. This may have changed in the past 10 years but it was certainly true 10 years ago.

Quote from: Strat Isn't that semantics
I have always been under the impression that Arithmetic is +-*/ and Mathematics is everything else.
I'm please to say I do serious mathematics on a daily basis due to the nature of my work but catch me on an off day and I'd have trouble calculating my change at a shop!
But I agree with the OP, mathematics are beautiful; oh! has anyone spotted the mathematical theme in the Simpsons?

Just goes to show.. you can be good at maths but if you're not good at understanding the question...
