Please refer to: > http://www.grc.nasa.gov/WWW/K-12/airplane/pressure.html > http://en.wikipedia.org/wiki/Pressure In three dimensional vector algebra, force(F) and area(A) HAVE TO be vector. Pressure(p) is a scalar quantity. p=F / A =(F dot A) / A^2 =| F | cos(theta) / | A | (where theta is the angle between F and A) Area has 2 directions; choose one of its directions to keep cos(theta)>=0.

"There is every reason to believe that evidence will surface in favor of the CBB/FS, evidence that will be powerful incentive for science to search for more evidence, leading to deeper intuitive extrapolations, leading to searching for more evidence, and so on."

E.g. you have the "length" of a string, a scalar quantity, a vector value by assigning it a direction. However you chose the + direction for no reason and the -direction works just as well. You stated this "k/<a,b,c>=[k<a,b,c>]/[<a,b,c>^2] " as an equality whereas it is not. The right side is a well defined vector whereas the left side is not a vector at all. Pete |
