<p>The day after Christmas when prices for things go down in stores and everyone goes shopping. Everyone except me. I can’t deal with all that excitement.</p>
<p>Yeah, JB, seeing SI prefixes applied to liters is always weird. Silly attoliters and femtoliters.
In Canada, we’re required to know what all the prefixes mean.</p>
<p>We are too. For science. Well, we learn them, and then we never use them again. I never saw the word “exometer” after the matching quiz. I’m not really sure what the point of that style of teaching is.</p>
<p>In physics classes when we do calculations, if the answer is in scientific notation, we’re required to give it using the prefixes as well. I don’t know, it’s one of the few things I’ve ever had to memorize in my science classes, and it is kind useful. For my mentorship program, the scientists always use the prefixes. They don’t use all of them, obviously.</p>
<p>Prefixes just complicate things. If you don’t stick to meters and kilograms in physics, a lot of the other units can get messed up. I hate when problems have Imperial System units though, that’s the worst.</p>
<p>I really have no knowledge of the Imperial System. They don’t teach it to us here at all.</p>
<p>And yeah, prefixes do complicate things. You just have to convert everything back to the standard scientific notation when you do calculations and its stupid. I guess the only case in which it’s sort of useful is when actually talking. It’s easier to say “3 microliters” than to say “3 x 10^-6 liters” for example.</p>
