Does reading the text help us understand what Physics is all about?  
A Scientific Theory


Time
(seconds) Mass (kilograms) Distance (meters) 

We
are on the hunt for the Higgs
Boson. . .maybe then, we will know mass!

Dimensional Analysis  
Significant Figures. . .are important!!  
I, II, II  
The
use of significant figures in our measurements are very
important. 

For
example; I say I am 6 feet tall. Is this correct? 

Sure,
to one sig fig! But, I am really not being honest. I am really 5'7''. 

This too, is not exactly correct, if I measure my height with a tape measure, I can get as close as 5'6.75''! You see, I am exaggerating my height because I feel small!  
Sig. figs. are important. They tell us what the best measurement is at any certain time.You can't arbitrarily use as many sig. figs as you want!
