Comment Re:What will it take to reduce CO2? (Score 1) 961

Well, we know plants frigging *LOVE* the stuff... so if we don't we can probably anticipate higher crop yields.

Unfortunately, it's not that simple. For example, increased temperatures will stress food crops. More information is here.

They said the oceans would rise by 2009.

And, the oceans have been consistently rising.

But so far, the models created based on the presumption of the association keep breaking down and their predictions don't play out as expected.

Again, this assertion doesn't stand up to scrutiny. Models successfully reproduce global temperatures.

Comment Re:PI not TAU in Euler's identity (Score 1) 298

Time to read the article: e^(i \times \tau) = 1 + 0. The reason that e^(i \times \tau / 2) = -1 is because \tau / 2 = \pi corresponds to a half-rotation. So, you can get the same result, only with a more intuitive answer because the amount of rotation is built into the equation. This helps to understand that e^(i \times \tau / 4) = i because i corresponds to a quarter rotation.

Comment Re:Sunbeds, cause cancer, not this? (Score 1) 386

The fact that cosmic radiation is greater than backscatter radiation is a red herring. You need to compare cosmic radiation vs. cosmic + backscatter. Unless the backscatter radiation is zero, the latter is always greater than the former. All that matters is the absolute danger of backscatter radiation. In a purely utilitarian sense, the question is: does backscatter prevent more deaths than terrorism causes? Given the lack of planes dropping out of the sky, I'm convinced that the backscatter is causing more harm at this point than the "bad guys." Not to mention the time and money being invested in "security" that could be spent on something beneficial (say, cancer research?). Or, the intangible cost of abandoning privacy.

Comment Re:The price of easy and automatic (Score 1) 274

I find Autorun very convenient. I carry my personal files on an encrypted USB drive. When I plug the drive into a USB port, it's convenient to have the Truecrypt mounting software auto-mount the encrypted drive automatically (well, prompting for the password automatically). Navigating to Start, Computer, arrowing to the right USB drive, opening that drive, arrowing to the auto-run file, and entering a password is much more complicated than entering a password. This is an operation that I perform on average once or twice a day, but sometimes more if I'm moving from computer to computer.
