dimensional analysis: more important than you think!

A frequent KTM visitor wrote to direct me to this website , which contains important information about how the failure to learn dimensional analysis can negatively impact your life.

Just listen to this; the pathos is heart-rending:

"I was a Wilton High School student who dozed off while Mr. Laptick taught us dimensional analysis in physical science. I never quite got the hang of it. It irritated me... all of those fractions. I never really liked fractions. Although my grades had been pretty high, I got a D in physical science and subsequently dropped out of chemistry in the first quarter of my junior year. It was not long before I started on drugs, and then crime to support my drug habit. I have recently learned dimensional analysis and realize how simply it could have solved all of my problems. Alas, it is too late. I won't get out of prison until 2008 and even then, my self image is permanently damaged. I attribute all of my problems to my unwillingness to learn dimensional analysis." -- Jane

I was shocked. I think given the seriousness of these testimonials, we should redouble our efforts here at KTM to ensure that every child is taught dimensional analysis at the earliest opportunity.

(One more amusing little sidenote: the hit counter at the bottom of the page never increments.)

2 * pi * r

pi * r^2

Area is the one with r^2 (length * length)

Perimeter is the one with just r (length)

This helped me when I was young. Perhaps it will help keep somebody out of jail.
