In my first year Physics class (1965), they took a totally different approach. I was in South Africa which at that time still used imperial units. We studied Bernoulli's equation fairly early on - an equation that relates fluid flow, pressure, pipe diameter and fluid head. In our first test a problem was presented to us in a variety of inconsistent units. Unless you got your units right, you got the problem wrong. I never forgot that test.

Between that and grant-sponsored research, I think the only time I have real exposure to Imperial is at the hardware store Saturday morning.

Several people who had previously been opposing it saw how easy it was and now like it, and several people have agreed that even though it's not what they would prefer they'll use it "just for this one class". There were still a few diehards that were complaining about it but that number shrunk drastically from the original. Now if only the problems themselves would get more understandable. I have a feeling that this will be one of my more challenging courses this semester.

The first day in September we cover meter, kilogram, and second, along with uncertainty and significant figures. Imperial units are never mentioned, and never asked about in class.

Actually, my experience has always been that physics mostly uses metric. I think in all intro-level physics classes I had in college, the metric system was introduced at the beginning and used throughout. I went to school at the University of Texas at Austin... don't know if we're just special or what. Certainly, in my electrical engineering courses there wasn't an inch to be seen. My dad is a community college professor of biology. I didn't know if he had any particular feelings regarding metric units, but when I mentioned to him that I was interested in promoting US metrication, he responded supportively, quickly pointing out that in every bio lab he teaches, he has to waste time explaining metric units to his students. He added that he always makes it very clear to them that "the only reason we have to have this stupid section is because this is the only country in the FREE WORLD" [emphasis his] that refuses to use reasonable units. I think there is a lot of simmering, silent, but strong support out there, especially among educators, scientists, and engineers. It's just that what happened in the 70s kind of wiped out any feeling of enthusiasm among most people that the US could ever change, even if it wanted to. --- Patrick Moore <[EMAIL PROTECTED]> wrote: > I wonder if the professor was consistently hard core and used radians (not > degrees) for plane angles. > > > > From: Mike Millet <[EMAIL PROTECTED]> > Reply-To: <[EMAIL PROTECTED] > > Date: Wed, 16 Jan 2008 23:12:18 -0700 > To: "U.S. Metric Association" <[email protected]> > Subject: [USMA:40109] Metric in Physics class > > > By some random curse this semester the only science class I could take that > fit into my work schedule was Beginning Physics. > > I wouldn't have taken it except for the fact that it fulfills my goal for > the general credit and I figured I may as well give it a try.
