Professor shoots ping-pong cannon in physics class

(6:49) Professor Harold Stokes at Brigham Young University demonstrates the effects of pressure with a ping-pong cannon. Do watch until the end, it's worth it.

14 pounds per square inch, still not SI units...

14 psi/inch^2 is approximately 96,526.64 pascals. Does that help you understand better? Not me because that's not a common measurement anywhere. I don't put air in my tires at the SI units -- just the simple PSI. Considering that he was referring to the atmospheric pressure, he should have just stated the pressure is at 1 atmosphere which is actually 14.6959488 pounds per square inch.

I believe the point is that when teaching a physics class at university level, it is counter productive to use the old Imperial units instead of the scientific standard SI units. You can still come across papers written by Americans using those units and that the requires a conversion to standard before it is usable. ...Oh, just saw "Brigham Young University (often referred to as BYU, or sometimes just the Y) is a private university located in Provo, Utah. It is owned and operated by The Church of Jesus Christ of Latter-day Saints (LDS Church)" Guess I wont be reading any science related papers by any students of his class anyway then ;-)

It is not uncommon for an academic to introduce an idea using words and measures familiar to his students, then to introduce more precise terms later. That is simply good pedagogy. Further there is no scientific journal I am aware of that uses non-SI units. The submission instructions implicitly state that SI must be used. By the way, Dr. Stokes has 96 publications in international, peer reviewed journals, and the scientific research database Web of Science has 16 publications in Nature from BYU, and 36 in Science. These are two of the most prestigious science journals in the world. Of course this is nothing compared to Oxford (whose motto is "The Lord is my Light") - 2,238 and 617 respectively. Still, Joe, if you read science papers you can't claim you won't be reading anything from BYU, unless you do that by choice.

Nicely done, glortman. JoeTaicoon's comment proves once again that the only thing that stinks as much as religious bigotry is anti-religious bigotry.
