Comment Re:Fahrenheit: It's for telling temperature (Score 1) 1233

The advantage of Fahrenheit over Celsius is that it is bound to two very useful points: the temperature water freezes (32 Fahrenheit) and the temperature water boils (212 Fahrenheit). These can be used to predict things more easily, like is there a risk for icing on the roads, how does the frozen lake/sea hold weight and so on. Or just to know if a surface is above 212 degrees. Put some water on it and see if it vaporizes.

Comment Re:Measured data includes uncertainty (Score 1) 276

When a measurement is made, everything is expected to be done correctly operationally. It's not a measurement if someone misreads a yard stick, etc. What I mean is this: if you're sampling a small portion of a population, you can't assume that you selected a perfectly uniform, representative sample.

A good example of this is trying to find out the probability of a "perfect coin" to land heads. By perfect, we mean it is exactly 50% heads and 50% tails when thrown. If you throw it 20 times, you may very well not get 10 heads/10 tails. You counted everything perfectly, but since you had a limited sample, there was uncertainty in your measurement. Increasing the measurements decreases the size of the error bars.

Comment Freedom of assembly (Score 5, Funny) 630

You have the right to freely assemble, everyone knows that. But nowhere - in no so-called constitution - does it say you also have the right to hear when you're assembled. Nor do you have the right to leave the assembly retaining all your ability to hear.

Once we learn our civic rights, and what we're not entitled to, we'll be a much happier and easier people for the government to govern.

Comment Measured data includes uncertainty (Score 3, Informative) 276

Any measurement made requires two peices of information: the measurement and the uncertainty associated with that measurement. To present data as though its known with 100% certainty is misleading and incorrect. It seems pendantic to worry about uncertainty, but when you're dealing with small effects on the order of less than one percent, if the error bars are +/-2.5%, then it's absolutely incorrect to refer to the result as "jumping out".

"When cooled and squeezed very hard, the soft metallic element europium turns into a superconductor ... which, if harnessed, could make for more efficient energy transfer." After factoring in the cost of compressing and cooling a big long cable... In other words, not any time soon.

Superconductivity can be harnessed for efficient energy transfer. It's a boilerplate that is attached to any research associated with superconductivity to remind the general public whe they're spending millions of dollars on things which aren't available as direct dividends to their lives.
