I'm glad you did not post that in the jokes section.

Meanwhile, I hope you're all as excited about tomorrow morning as I am:-

09:09:09 09-09-09

On second thoughts, perhaps we need to be worried about this!

But, there again (and on third thoughts), I shall be well out of it all by 2048, inshallah.

With regards to the significance of number 9 today - 09/09/09, it is also the 252nd day of the year - 2+5+2 = 9. Spooky eh!

Glad to someone can still do maths, maybe you could help Scott Barlow with his velocity problem!

Had some thoughts on that. Reckon he should have a friend with a stopwatch handy. Elbow a punchbag (or similar) 10 times then divide the friends stopwatch time by 10 for the time of 1 hit. If he knows the distance he can then work out the speed. Trying to use a stopwatch for 1 hit would not be accurate enough methinks. I reckon though, it is acceleration Scott needs, not velocity (F=MA).

Yes, acceleration comes into it. That's probably what he meant here, I should imagine:-


But velocity shouldn't be dismissed so easily! After all, that's what "high velocity" weapons (as in small arms, tank guns etc.) are all about. And then we're back do giving up it's kinetic energy, as it (the bullet, or projectile, that is) decelerates ...er, rapidly upon impact.

Kinetic Energy = (Mass/2)*(Velocity squared) ... I think I've got that right (?) ... and all that KE gets given up into the ribs (or wherever) ... plus the elbow! All in Joules, of course.

Meanwhile, back to 9's and *252's. It's nice to discover, Mike, that I'm not alone!

* That was (is?) the number given to the army charge sheet, by the way - AF-252. See, numbers do matter!

No, you are not alone on the numbers game Geoff! By the way the reason that the 252 fact caught my eye is because in my day it was also the number of the RAF's charge sheet. Been caught out once or twice myself there!

On the numbers issue I read a brilliant (and useless) fact about the number for pi some time ago, but it is probably not relevant for this forum. Can PM you if you want it. I think you would probably be impressed, I certainly was, (unless, of course you have heard it already).

PM by all means ... but since when has doubts about relevancy prevented folk from posting on this forum!

Darn it, I missed it! I wish someone had told me!

Today we had the rare numerical phenomenon when the time and date read 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

The event (which is known as a Sequential Day), occurred at 12.34 pm and 56.7 seconds today while the date completed the pattern with 8.9.10.

The phenomenon is so rare that the last "pure" sequence like this fell at 01.23.45 am on 6.7.89, and the next will take place at 00.12.3 am on 4.5.67. That is, in 2067. Somehow, I don't expect to be reporting that one, however.
