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.

Numbers and Men In Skirts

As a kid I used to wonder why we had to learn our "times tables". Learning things parrot fashion , is not useful, especially when you are talking mathematics. Fast forwrd to "some time later"  and I find I don't have to look up , work out , or use a calculator to work out this simple multiplications, I just know them. And applying thouse concepts I'm pretty quick on working out the product of any pair of two digit numbers, but up to twelve I just know them, so actually learning the "times tables" benefitted me.

I am learning quite a lot about mathematics and number from my latest book feast, "How Not to Be Wrong: The Hidden Maths of Everyday Life" by Jordan Ellenberg which is just going through the differences between large and small sampling operations which has thown a lot of interesting concepts.

Tomorrow is the last day of the month so this week has been a rest from walking though I have still hit more that 7K each day so I am not being average, and from Tuesday I will attempt to do 340K steps in August and repeat that each month.

The last two days I have felt incredibly drained, and really not up to actually walking , and today I had the added extras of changing the bedding, mowing the lawn , and refilling the bird feeders. Added to that I think my phone is going through one of it's phases of not recording steps (a couple of normally 1K walks clocked at 200 steps), but I still hit 9K today and am 70K over the million for the last quarter.

Yesterday I was totally drained but I got myself over to The Doll at The Black Bull to catch Woment In Revolt (they are the ones in skirts) and you can see the video evidence here from a great night, but I was done by ten o'clock. I came home went to post the video online and managed to screw my computer by plugging in a USB cable. It then took an hour to do a restore, but all is good now and all seems to be working well. I've just had a look at the demographics of my audience for youtube and only 20% are female, I am not sure why that should be, but you could say  "C'est La Vie" as Chuck Berry once said , and we got the Pulp Fiction Twist scene featuring John Travolta and Uma Thurman for you to enjoy.

So the weekend is over and Monday is upon us, I hope to feel a lot more energised tomorrow, so I am going to get some sleep.
