Why can't I make this work? LED angst inside

Using a AA battery, two pieces of speaker wire and an LED, I am trying to make a simple circuit. I am meeting with complete failure. Help!

I read books for a living. I do not program computers, wire electronics, play with oscilloscopes, or regularly work on projects that require modulating a radio frequency. That said, I'm bored for the summer and looking for new projects. Choice A is a neat LED nightlight, and so I find myself (once again) trying to teach myself simple electronics, and (once again) meeting with middling levels of success.
Basically, I'm trying to wire an LED to a battery. I am following this
instructable. I am using a 1.5V AA battery and a 1.7V LED, using a lower-level power supply on the assumption that I don't yet have to learn how to wire a resister. I realize that there are TWO steps to this process - making the connections, and putting the LED in one of two orientations. And yet...my LED fails to light.
I realize that this is possibly the most basic question I can be asking here, but does anyone have thoughts on what I might be doing wrong? Pictures here
