Re: HS math preparation correlation to college



- simple circuits, Ohm's law

What class that is not physics would have covered Ohm's law?

Ohm's law was covered in a general science course I took in grade 9.
It was also covered in some electricity/electronics I had, also in
grade 9.

And WHY??

I have no idea why it was covered in a grade 9 general science
course. In a basic grade 9 electricity/electronics course, it would
be a more natural place to cover Ohm's law.

Most of them were either mostly experimental and/or the math was
relatively simple. Covering something like Newton's 2nd law,
diffraction, interference, etc ... would be largely pointless at
earlier grades.

Covering diffraction and interference in high school at all is
utterly stupid and pointless anyway.

Diffraction and interference was covered in a relatively shallow
manner, via simple Huygen's principle type of arguments. That's about
the highest it can be taught at the high school or freshman college
physics level. (Anything further would require looking at solutions
to Maxwell's equations).
