Subject: Re: [Phys-L] Conceptual Physics Course
On a related note, what do you do to convince a person in a lasting
manner that the reciprocal of (1/x + 1/y) is not, in general, x+y?
The units will not agree.
Also, just give some values to x and y and test the two versions.

Subject: Re: [Phys-L] Conceptual Physics Course Regarding the
question about algebra conceptual physics course, the other
monkey wrench in the works is that some of the students, I
would estimate about a third of them, will already be quite
good at algebra.
On a related note, what do you do to convince a person in a
lasting manner that the reciprocal of (1/x + 1/y) is not, in
general, x+y?
