Clock Mathematics


I was completely unaware of (or had forgotten about) the concept of clock mathematics. We all use it every day and when used in applied mathematics it can apparently be very useful. Basically its working with a  limited series of numbers which rill over when you get to the end. So an example that we may use every day is that if you say that you will see someone in four hours at eleven o' clock you both know you will meet at three o' clock. Therefore 11 + 4 = 3 not 15 because after 12 we roll back to 1. Apparently it's useful in Elliptical Theory. This is another concept that I have been (re) introduced to in Simon Singh's brilliant "Fermat's Last Theorem" ,and another reason why I love reading books.

As I'm writing this the sun has really come out and it's looking like a definite walk into work today.

Yesterday I put Half Man Half Biscuit's "Trouble over Bridgewater" and it has some great titles that maybe the songs don't quite live up to such as "Uffington Wassail" ,  but "Irk The Purists" is good and then I got hit with the absolut classic "Gubba Lookalikes" which is followed by the excellent "Mathematically Say" but then we are hit with the totally brilliantly funny "With Goth On Our Side" plagiarising Bob Dylan's "With God On Our Side".

The opening line is:

"Oh my name it is Dai Young"

And that is a brilliant play on words when the song is based in Wales and it's subject matter.

But I will share "Gubba Lookalikes" with you before I set out for work.
