the last tarboush maker in Cairo! This hat is for Robin.

Robin in tarboush.

My brother wears hats.  My brother is the perfect Arab gentleman, albeit 40 years too late.  My brother desires peace, but questions the validity of the premises given by the current situation in my part of the globe.  At least, I hope he does.  I hope everyone does. Sympathize with a Palestinian if you can. 

I haven’t even been home a month yet. This is a picture from my scenic tour with Meredith. A benevolent-looking cow-beast.

Nothing like being a box in the corner. Back to the old, better-than-nothing routine!

After all of two days, my Scientific Ethics course only garnered one email of interest – from a graduate student wanting to TA or audit – so it got dropped.  Such is life.  It will be offered again in the fall, and listed/promoted well in advance of registration, so hopefully there will be more interest then.  Instead, I’ve been assigned CHEM 103, Chemistry and Society.  I am happy with that.  More so than if I got stuck with a general chem lab.  It is still a class full of non-science majors, but at least they actually chose the course as an elective that interested them in some way, as opposed to a course that is only meeting a strict requirement.

Scientific Thinking is already off to a great start.  After the rough time we had fall semester anything would be an improvement, but the students in my sections this term are already aces in my book.

I talked with Adam a while back about how neither of us had ever actually read any Feynman, so I made sure Six Easy Pieces was included in the small library Emily smuggled overseas for me.  It seemed like a good place to start, given that I am a chemist and not a physicist (as opposed to Six Not-So-Easy Pieces, among others).  I have only just started it, but included in our repository of Scientific Thinking-related document files was an excerpt from a talk he gave to the National Science Teachers Association in NYC in 1966, on the topic of What is Science?, so I decided to give it to my classes as the first reading assignment on Sunday.  Today I walked them through the whole thing with a slick powerpoint (sorry openoffice, I really like you and use you whenever I can, but presentation just doesn’t cut it).  You can read it for yourself, but the closest Feynman comes to an actual definition of science is the following:

Science is the belief in the ignorance of experts.

Everyone seemed to like that.  It only seemed fair, then, to talk a little bit about the expert/author of the reading, Richard Feynman.  By the end of the class I had everyone staring up at the light fixtures as I flicked the switch on and off, on and off, attempting to explain Feynman’s Quantum Electrodynamics (QED) to a room full of freshman business and mass communications majors.  Common sense tells us the light waves we perceive have travelled the shortest distance between the two points, the bulb and our eyes; QED tells us the path travelled is actually the sum of all possible paths between the points.  Absurd! And yet, the fundamental theory on which QED rests is the same on which all of modern chemistry depends.  What better way to illustrate the true nature of Science than to highlight a model which best explains the evidence and observations we have to date, and yet is so contrary to common sense that you can’t help but seek a better one?

I went 7 minutes past the end of class today, blabbering on about double slits and single particles interfering with themselves, and not a single person got up to leave when they rightfully should have.  Someone in the back wondered aloud if Relativity was not equally absurd, and I tried to keep my cool as a wave of goosebumps covered my body.  Not a single person even brought the overtime to my attention, and I eventually called an end to class, myself, with multiple enthusiastic hands still in the air.  In all my experience of teaching, this was a first.  No barkin from the dog, no smog; today was a good day.

Alie missed us

Brandon’s dad sent us this picture of Alie while I was still in Cairo. I think she is still harboring a bit of resentment. I never knew until now that it was her lifelong dream to ride a camel at Giza. I keep telling her that Marti didn’t get to ride the camel either, but it’s no use. At least she finally seems happy I’m home now, and thank goodness, because I would otherwise be pretty lonely. Too bad she doesn’t cook for me.
