This is also in the post above, addressed to Luis, Dick and Esteemed Writers:

Dr. Dick is PROVEN right on at least one point right here with a minor example, as follows:
Physical laws CAN be confused for conditional equations. I found one rightCheer in my Pre-Calculus Math book.
Paraphrased without ANY context shift, they said "A=1/2bh is a law of nature when the letters mean 'area = 1/2 times base times height.'"

But while that's true for triangles, it's not true for other geometric forms. So, on this SIMPLE level, this book let that little declaration pass for truth. Do you believe
A=1/2 b h when the letters mean "area=1/2 times base times height?" I don't agree that it's true without conditions...not true universally!
The triangle is an existing example for which it is true, and we love to cite it.

You see they CAN make that mistake!
If you doubt what I am saying, I can give you the book title and edition number, etc....
ISBN, or could post a photocopy of the page on my website if you want...
