2 sigma means a 95% certainty, and 3sigma means a 99.7% certainty.
So at just 2 sigma, 1 in 20 times you will get it wrong/fail. I would hope that in medicine and biochemistry, where it matters, that they do use 3 sigma certainty.
In particle physics, a 5 or 6 sigma certainty is usually used for confirming a new particle, which means that you're wrong only once in a couple of million times (although guessing at the errors is probably itself the most significant error.

No, nobody has ever considered the safety. Since you are so brilliant and have just thought of it by yourself, you should quickly write them a letter and tell them. I'm sure they'll be appreciative.
I want a president who surrounds himself with smart people and listens to them. That's a smart leader, not necessarily one who is the best at everything.
I'm sure that wheeled robots were around for a long long time before one was sent to Mars or the Moon. So just existing for ages without being used doesn't mean much
In reality, by the end of the project you are creating new backlogs as fast/faster than fulfilling them. There's always code that needs to be redone, newly found bugs to fix, performance testing that needs to be done, etc. You can't "create and agree" on performance, debugging etc backlogs ahead of time.
Actually if you do point red lights at a point, some (very few I admit, but still non-zero) of them will "turn blue", since blue is almost the same energy as two photons. It's called two-photon absorption. http://en.wikipedia.org/wiki/Two-photon_absorption
And have the private key downloaded completely everytime you swipe the card?
The only way it could work securely is if the card itself had the electronics built in to do the cryptography. Then when you swipe your card to pay for something, the device would require the card to OK the transaction.
I wonder if this will have any impact Ubuntu's recent announcement that they are switching to use Yahoo (which is Microsoft Bing underneath) as the default search engine in their next release.
Huh? Transcendental numbers can be real. In fact, almost all real numbers are transcendental. It just means that it can't be a solution of a polynomial (e.g. PI can't be written as the solution to 0 = ax^1 + bx^2 + cx^3... )
The problem isn't just that a few bad apples do bad things. That happens in every organisation.
The problem is that the rest of them tried to cover it up, were complacent about it, and wanted the 'punishment' to just be a bit of counselling by other priests. Read http://en.wikipedia.org/wiki/Catholic_sex_abuse_cases for a pretty chilling summary.
They also used the whole thing to ban gay men from becoming priests. Funny that.
It's really measuring current - as in how much current flows through a piece of metal. Strain can be derived from that, as the resistance depends on the strain the metal is under.
Consider when a typical application exits. It does something like:
* Write new config file to a temporary file * Rename the temporary file over the top of the old config file
This way if the computer crashes, applications expect the config file to always be valid. i.e. they expect the data to have been written to disk, completely, before the rename happens.
This worked in ext3 and other filesystems, but originally not in ext4. The result was that the config file could end up being empty.
Heh, I was thinking exactly the same thing - high orbit kinetic missiles.
Another option - teraform. They must have the technology to change the atmosphere. So they could do that to make the air breathable for humans and (presumably) thus not breathable for the Navi. Might take a while, but then you'll end up with a breathable planet with no life and just the rock that they want.

Uh, if there's a broken symmetry then it does matter.
Does it actually matter?

For such a long rant, you didn't seem to given any reason why it won't.
Huh?
Nobody can know, before hand, how long it is going to take to do the testing+fixing and performance increases.
If you have to acheive, say, 30fps, then how can you tell how long it is going to take to reach that? How much effort will it be?

Try to start a movement to call it Microsoft's OOXML. Or MooXML :-)
Okay let's see.
A mobile phone can emit about a 1 watt. So say you talk for t about of time, so 1 watt * t joules of energy.
The energy of each photon from a mobile phone would be, E = hf = h * 900 MHz.
So number of photons emitted is: t / (h*900Mhz).
The cross section area is about 10^50, so, roughly, you'd need to talk for .. about 10^18 years. Far far longer than the age of the universe.

Uh, two-photon absorption can, and does, happen.

Sure, I do condemn it everywhere else as well.
Indeed, I'm going "eh" because almost all real numbers are transcendental.

Urgh, I hope you really didn't say it out loud in the cinema.
