onClick also causes the browser to open a new Explorer window. I ask her if she happened to set an
a href to nothing. (Yes.) Then another student helpfully chimes in, “Yeah, you should just set it to #”. At this point, I’m pretty much irrelevant, so I say, “Hey, if you have any other questions, ask him.” I like this, because I get to step into the role of asking why things work or what they mean, rather than dispensing facts.
As I’m walking away, I hear her ask him, “OK, what’s the square root of negative 1?” And he says, “i.” And she yells after me, “He knows!”
