I work with an engineer who thinks it's 1940. Previous companies I've worked at allowed solid models to define parts with only the critical or inspection dimensions required on the paper drawing. He wants every single dimension on the paper drawing, but that takes much longer, plus is less acurate because changes to the model don't always correctly update on the drawing. Does anyone have a book or magazine article showing that solid models are acceptable for part definition? Thanks in advance.

Sqrt = square root

Thank you very much in advance!

Absolute Zero (0K)(-273....C) is the Temp at which all elements, compunds etc. are in a solid state, so then why are nebulae and other things in space refered to as gas clouds????

1. Derivative of a constant function rule, 2. The power rule, 3. The constant multiple rule, 4. The sum and difference rules

f(x) = (x^2 + 4x + 3) / (x^(1/2))

Is it possible using only these rules? Or do I need to use the definition of the derivative to solve this?

My book says the answer is: 2/3√(x) + 2/√(x) - 3/(2x√(x))

Work out this problem:
pi x 0.000376^2/4

Then multiply the answer by 4.1758
When using pi, use the full number on a calculator, not just a few digits.

Intel to reveal 80-core supercomputer processor
DigiTimes - Feb 12, 2007
Intel on February 12 announced that its researchers have developed the world's first programmable processor to deliver Teraflop (one trillion calculations per second) performance from a single, 80-core chip.

I have a hard time imagining one trillion of anything. (Except maybe cells.)
