Two points regarding my recent mention of the Space Elevator article:
(1) As J. Ward pointed out (see below), the unit could have been specified in pascals (Pa) or one of the multiples of pascals (MPa or GPa). It is correct to use either N/m^2 or Pa, but I will bow to Mr. Ward on the matter of what is more common usage in the industry.
(2) I am embarrassed at having mistyped the symbol for newtons in the expression "N/m^2" (also see below). I apparently missed my shift key and so I typed a lower case "n" by mistake. Easy to do, but I should have proof read my msg better before sending it.

The author alternatively could have said 130 GPa, which is more consistent
with the common practice of stating tensile strength in MPa and GPa.
