math quest

Ask MathaFilter: If I square 100 mm I get 10,000 mm. But, convert to .1 m, and square, we have .01, a smaller amount! Why can using a conversion like this give a nonsensical answer? If I want a length times itself why does it matter the metric?

What was this geometric creature builder website?

Several years ago, I saw a website with a fun little flash or javascript applet thingy where you could build little tensegrity structure creatures, then have oscillating movements applied to the pieces, so that the structures would seem to "walk". I don't remember what it was called! From memory, one of the simpler structures looked sort of like this. What was it? Is it still online? [more inside]

Some good books to re-learn math?

I'm teaching myself to code (Python, mainly), and it's going well, except I keep on running into one big problem: I haven't done any math since high school (6 years ago). I used to be top of my class, and now I can't do simple word problems anymore. This gets tough because they inevitably pop up in the books I'm using, and then I stop dead in my tracks. Could anyone recommend a couple of books or web resources to help me get back up to speed? I never took Calculus, so a good Calculus book would help, too. [more inside]

Linear Relationships in Real Life?

I am redesigning a high-school Algebra course so as to make it more meaningful to the students. To that extent, I am trying to gather as many examples throughout our world of linear relationships. I was hoping to tap into the collective wisdom of this group to come up with as long a list as possible of linear relationships that actually exist (not contrived stuff). I once knew a teacher who had a plant that grew at a linear rate. I don't know the type of plant, however. And there are so many other linear relationships around us. I don't want everything they see be about a car's distance from home or the amount of money they saved. What do you know of that exhibits a linear relationship? I'd love to have a long list for students so that they see that studying linear relationships in Algebra really does matter. Thanks for any help in making this course more worth while to the students!
