Wire Like a Physicist

One of last year's physics majors is spending the year in rural Uganda working at a clinic/ school there. He's keeping a blog, which is intermittently updated by western standards, but remarkably up-to-date given where he is.

This week, he blogged about putting his physics education to use:

I have been doing a lot of electrical work the last two days. I connected a laboratory and rewired the whole system so that some safety switches would be in place and so that I would be the sole person with the knowledge and ability to decide who will have light. Actually, it is to break it up so that we don't destroy the inverter. It was a huge puzzle as I haven't ever wired something by myself before and almost every wire I picked up had a different color scheme. Blue/Black/Red, Purple/Blue/Green, Blue/Red/Green and more. I did all the wiring without testing anything and then, after three hours of darkness (I started at dusk) we flipped on the brand new master switch and all the new nooks and crannies had light. I was astonished that nothing was on fire.

I'm so proud...

Later in the post, he talks about his experiences teaching an advanced physics class at a regional school. The whole thing is worth a read. So, well, go read it.

One of our 2008 Physics majors is currently in Uganda, working at a clinic/ school in a place called Ddegaya (Google doesn't recognize it, but it's somewhere around here). He's there as part of a program started by the college last year, which sent eight students abroad to work in impoverished…
This year's "Flame Challenge" asks scientists to explain color in terms an 11-year-old can understand. The rules limit answers to either 300 words of text or a 6-minute video. 300 words is ridiculously short, so video is clearly the way to go. Of course, I'm not much of a video expert, but then,…
This is an early post of mine concerning the approaches to teaching science. It was first published on March 15, 2005. I have employed both of the methods described in this post since then. The jigsaw puzzle works much better as it is more fun. I have described how it actually went in the…
Days before the 12th anniversary of the 9/11 terrorist attacks, the New York Times published an article about respirators. This protective equipment was intended to protect response and recovery workers at Ground Zero, but often failed to do so because of discomfort, inadequate training, or…

When I went to high school, and dinosaurs walked the earth, we all had to learn wiring and wood shop and mechanical drawing. The use of appropriate technology in Africa and the underdeveloped world is extremely important, and the linked-to example is very good.

Because 3rd world has little sunk cost in 20th century infrastructure, 21st century and 19th century tech can be retrofit simultaneously. But only by people who know what they're doing.
