No I didn't.

I did notice one part of the summary where they converted 100 km to 62 miles, and another where they noted that different groups define the edge of space differently, with some using 100 km as the boundary and others using 50 miles. However, at no point did I note someone trying to equate 100 km to 50 miles. Can you point it out for me?

Both of those options are stupid. If someone sends a text to your phone number, and that number is associated with an iMessage account then it should try to send the message via iMessage, and when it doesn't get delivered to your phone - regardless of if it gets delivered to any other devices - it should send a text to the phone number.

Sapphire is hard... 9 on the Mohs scale, and the only substance harder is natural and synthetic diamond.

Lots of things are harder then Sapphire, particularly carbides and borides. Examples include silicon carbide, titanium carbide, boron (the hardest element) boron carbide, and boron nitride.

I find it difficult to believe... so...do you have any references that says Gorilla Glass is cheaper and harder than Sapphire?

No one ever said it was harder, they said it was stronger.

Nobody seems to be asking what the definition of "50% of the time" is ?

Over what interval/time frame?

If the opponent throws scissors or paper on his first move is he then required to throw rock on his second move?

Probably because they read the link which describes how "50% of the time" is determined.

Ideal follows a very consistent color scheme. Grey outside, yellow instrument face.
Fluke also follows a very consistent color scheme. Yellow outside, grey instrument face. The only exceptions appear to be instruments designed for very specific environments where you want to be damn sure your meter isn't going to cause an explosion, which appear to be red on the outside.

If you showed me 50 meters from those two companies I'd have no trouble telling which belongs to each based on the coloring scheme.

All you seem to have shown is how exact a copy the sparkfun meters had to be to run into trouoble, because something as trivial as inverting the color scheme is enough to avoid it.

So I give up. What was the point you were trying to make?

Just say the Coulomb is 6.24150965e×10^18 * (the charge on an electron), and the amp is 1 C/s. The resulting 25ppb uncertainty in the definition of the Coulomb is probably better then anything you'll get out of trying to realize the current standard.

The current (early 2011) uncertainty in Avogadro number is about 30 ppb. The current uncertainty in the hunk of metal is about 20 ppb. I don't think the International Committee for Weights and Measures would consider making a switch unless it is one that would reduce uncertainty.
