So today we discussed rounding in physics, and I have come to the conclusion that there is only one correct way to round: 0,1,2,3,4 always round down, and 5,6,7,8,9 always round up. The argument for this method is this: when you have a measured value of 0.0, the average actual value that comes to is 0.05, because each extra digit averages to 4.5 and adding them up you get 49999... which is 5. Therefore the average actual values for measured values are: 0 = 0.5 1 = 1.5 And so ...
First, read this news story. http://www.thestar.com/news/gta/article/637592 So today at my school which is pretty close to the bloor + christie intersection, we had a lockdown as well, which kept us in through our normal lunch hour until 1:40, at which point we got a 45-minute lunch break before two shortened evening classes. Honestly is it that hard for these morons to tell the police before a lockdown drill, in the same way that we tell the fire department when our fire drills are? Another ...
As some of you know, I live in Canada, and in Canada we use the metric system. The metric system eliminates fractions in conversions in favor of simple powers of ten. However, there are still things in this system that I loathe. First, the unit of length in the metric system is metres, abbreviated 'm'. The unit of area is square metres, an area of 1m by 1m. This is abbreviated m2. The next unit up in magnitude is square kilometres, an area of 1000m by 1000m. It is abbreviated km2. ...
Today my dad needed to extract the text from a pdf. Sounds easy, right, you would just click and drag, then ctrl-C/ctrl-V. Alas, no. Adobe Reader allows the pdf to make it impossible to copy stuff onto the clipboard. Similarly, a pdf can make it impossible to print it. When my dad explained this situation, I found it incredibly weird. You press ctrl-c and it goes 'boop'. You go to edit>copy, and the button is gray. To someone who uses Linux, it seems like a rebellion, as if a hammer said, "No, ...
So today I got thinking about the strange obsession our media has about "teens". No other subject seems to create as much worry as our "online safety", our "depression", our "anxiety", and so on. And yet, no word on any sort of cause other than "They're teens" "they don't think like adults" "they haven't matured". But still, let's check out the origin of the word "teenager".It first appeared, by most accounts, in the ...
