Instead of describing the science I'm seeing this week at the DAMOP meeting, I decided to do a couple of meta posts on conferences in general. This first one discusses what happens at a science conference and what to do while you're there.

I'm still amazed that we can measure relativity in such a simple way as putting clocks on airplanes.

For a couple of years I've been polishing up a classroom activity to demonstrate how quantum measurements work on a simple qubit system. Here I'd like to summarize the game in simple terms for non-experts.

Before I describe how we measure lead in drinking water, I want to discuss some of the new (to me) meta issues associated with this project. A lot of these things are uncommon for physics research, but will be familiar to folks in biology or medicine. I am a rank amateur on these issues, so consider this an imperfect discussion by someone still finding his way.

I found a different way of using a french press coffee pot that keeps the coffee from getting bitter if you don't drink it right away.

One of my major research projects is building an inexpensive handheld device for measuring the amount of lead in drinking water. This is the first of several planned posts on the project. Today, I'd like to introduce the problem we're trying to solve and talk particularly about lead in Pittsburgh's drinking water.

I read a lot. It's probably my biggest hobby. Here's what's sitting on my desk or in my ebook right now.

Most of us are familiar with the refraction exam done by optometrists to determine our eyeglass prescription. Here's a different method without the fancy equipment. The only tool we need is a tape measure and an object to look at, like a chart or point-source of light like an LED.
