Winter wonderland? Depends on your point of view I suppose. This little traffic mishap had the whole east-bound public transitway on hold for a few hours. Luckily it wasn’t very cold out, so the 2km walk to work was almost enjoyable! Did anyone get a photo of the mass OC Transpo exodus and/or line of busses? Saw many taking pictures with their cell-phones. If you have a picture leave a comment with a link! (Thanks)
Needless to say, got to work almost two hours later than intended. By the time I was done my day’s work, it was well into the evening so I dropped by the Mayor’s Christmas party on the way home. Nice night for it, and there was some cool entertainment. A great event if you have a young family and like getting tons of free stuff.

fixed the template for this site, sort of stupid since it won’t be around for much longer… the new year will bring some changes (and a sweet new design to a much more professional site: jgarlough.ca ). tick tock O’6.
I’m blessed to have friends with more wit than I. From a discussion earlier this evening:
So the woman dumped me for her invisible friend. Turns out they were more than just ‘friends’.
You can’t live in the country without hearing at least a few cow-tipping stories, and it always bothered me that I never got a straight answer when I asked about said event. The British Times has published a story about some Canadian “academics” that has caught my eye:
Margo Lillie, a doctor of zoology at the University of British Columbia, and her student Tracy Boechler have conducted a study on the physics of cow-tipping.
A cow of 1.45 metres in height pushed at an angle of 23.4 degrees relative to the ground would require 2,910 Newtons of force, equivalent to 4.43 people, she wrote.
Dr Lillie, Ms Boechler’?s supervisor, revised the calculations so that two people could exert the required amount of force to tip a static cow, but only if it did not react.
‘The static physics of the issue say . . . two people might be able to tip a cow,’ she said. ‘But the cow would have to be tipped quickly – the cow’s centre of mass would have to be pushed over its hoof before the cow could react.’
Newton’s second law of motion, force equals mass multiplied by acceleration, shows that the high acceleration necessary to tip the cow would require a higher force. ‘Biology also complicates the issue here because the faster the [human] muscles have to contract, the lower the force they can produce. But I suspect that even if a dynamic physics model suggests cow tipping is possible, the biology ultimately gets in the way: a cow is simply not a rigid, unresponding body.’
Another problem is that cows, unlike horses, do not sleep on their feet – they doze. Ms Boechler said that cows are easily disturbed. ‘I have personally heard of people trying but failing because they are either using too few people or being too loud.’ Plus, ‘Most of these “athletes”? are intoxicated.’
So it seems that cow-tipping may not be possible. (I know some young farmers who have some explaining to do). The research also bring about two more questions: 1. Why weren’t there any field tests?!?!? and the second OBVIOUS question How many friends do I need to tip a horse?
