Linear algebra for game developers – Part 1 (2009)
I'm not sure how much someone who wasn't already familiar with vectors could get out of this. This seems to be a common issue with informal lessons like this[1].<p>The article starts seemingly assuming you have no idea what a vector is, but after showing a few graphs opines "As you can see, a vector by itself is just a set of numbers". I don't think someone who didn't already know what a vector was and how to recognize a vector on a graph would see that. Reading the next sentence about coordinate pairs and referring back to the graph might get you somewhere I guess. It doesn't seem to know who the target audience is supposed to be.<p>Trying to teach people things that you use every day and have throughly internalized can be an eye-opening experience. If you're trying to teach someone how to count in other bases and discover that they never learned about exponentiation, you're not going to get away with just saying "it's repeated multiplication and the top number is how many times you do it; oh also anything to the zero power is one (except zero itself...), and also negative numbers do this... and fractional exponents do that...". They're not going to suddenly "get" exponentiation the way you do from years of experience from three minutes of offhand remarks.<p>[1] <a href="http://hentenaar.com/dont-learn-c-the-wrong-way" rel="nofollow">http://hentenaar.com/dont-learn-c-the-wrong-way</a> (parts 3, 4, and 5 in particular have similar complaints)
