I would define fuel input energy as the heat released by burning the used amount of fuel, and electrical input energy as the heat released by running the amount of electricity used (by the charger, not the motor) through a resistance heater.
So, you'd need to change your fuel energy definition. Otherwise, a car that blows half its fuel, unburnt, out the tailpipe would consume twice as much gas as its efficiency implied. Also, a fair amount of the heat gets dumped into places like tires, which is not easily-measurable. Typically one defines the energy of fuel as the heat energy it releases when burnt in a particular (and efficient) manner. Unfortunately, there are multiple definitions that fall under this, so there are a couple of different "energies" for fuel. Electricity is easy -- the heat emitted by an ideal resistance heater is simply the energy of electricity consumed, which we're already good at measuring.
I'd prefer a unit of heat energy to one that looks like electrical energy
Well, it's all energy. BTU is asinine and nobody knows what it is, calories are unused and Calories are for food (don't suggest that people should drink gasoline). You have either Joules, which nobody is familiar with, or kWh, which people are familiar with through electricity. Screwed either way.
They're not really talking about the Pioneer anomaly, just pointing to it to claim that relativity is "wrong". The inclusion of some legitimate questions in physics doesn't magically make the whole list respectable, though. I refer mainly to things like this: "The action-at-a-distance by Jesus, described in John 4:46-54."
Besides a few whoppers, the list consists mainly of already-solved problems and grossly misguided logic.
This boils down to doing a heap spraying attack, and those are in the general class of exploits that ASLR (and to a lesser extent, DEP) are designed to prevent. However, it's fairly well-known at this point that ASLR can be defeated (sometimes) by well-crafted heap-spraying attacks. (Likewise, DEP can be defeated by stack-smashing using return-oriented programming.)
Don't they essentially do that with the labels shown, except turn it into a more compelling number -- dollars saved (or spent) on fuel relative to the average?
You mean like the second label shown in TFA, which has a section (with a helpful little battery-shaped box to help you find it) that indicates the charge time?
That's weird, because the label they show in TFA is clearly for an electric car, and it lists the following figures: kW-hrs/100 miles, MPGe city, MPGe highway
As I'm sure you're well aware, kW-hr/100 mi is not a rating in miles per gallon. The other two figures are miles per gallon equivalent and are to facilitate comparison across fuel types.
To be fair, "historical facts" is a term generally reserved for human events that have been recorded in writing. In science, you typically call them "observations". A good set of terms is that the mathematics based on your observations that is supposed to predict future observations is a model or, if it's successful, a law. The explanation of why your model works and how that fits in to the rest of known science is a theory.
Which means for any reasonably complicated field that can be cast under one umbrella, "theory" is the word that will be applied to it, like "theory of gravity" or "theory of relativity" or "electromagnetic theory". It's a collection of models and some thoughts as to how it is they're all connected.
This is more intrusive than infrared imaging. In both methods, the user can "see" objects that they couldn't see without entering the house or searching the car. X-ray backscatter is an active method, though, sending X-rays at the target and measuring the results, rather than measuring radiation the target was emitting to begin with. I can't see how this will hold up in court, unless it's designed so that it can't "see" objects, but only "detect" very particular classes of objects (e.g., the presence of explosives) and is only used in particular situations where warrant protections are not as strong.
There is a background level of ionizing radiation that is more or less unavoidable, and there is an average yearly exposure level due to environmental exposure. As such, there are certainly quantities of radiation exposure that are negligible compared to environmental exposure.
For that matter, there are legally-defined acceptable levels of occupational exposure to ionizing radiation. (I worked at a synchrotron, where exposure to high-energy X-rays is unavoidable and carefully measured.)
The reason the dental technician leaves the room when she takes your X-rays is that medical X-rays are actually quite a respectably-large amount of radiation and the technician does quite a lot of X-rays per year.
Don't antennas generally need to be on roughly the same scale as the wavelength of the radiation they're interacting with? X-rays have nanometer-scale wavelengths.
With X-ray exposure, quantity is important. You don't need to be informed that you'll be exposed to X-rays when you fly in an airplane or turn on an incandescent bulb, but you are.
With the way DC is designed, if you drive around randomly, you'll probably run right in to the National Mall. The Lincoln Memorial is that big building pictured on the penny. It's across a reflecting pond from the building that looks like the Washington Monument. Sort of in the vicinity of the capitol building, the White House, all of the tourists, and a bunch of Glenn Beck fans.
I might add that on the Google map that comes up when you search for "Lincoln Memorial" and get the wrong answer, there's a dot a short distance away labeled "Lincoln Memorial". It's that one.
There is actually a distinction in Chinese between the written and spoken languages. Zhongwen, written Chinese, is largely the same everywhere. Hanyu, spoken Chinese, has many drastically different dialects.
It's more like saying someone's mass is 686 N. You can guess the correct answer if you make a reasonable assumption, but the statement's wrong. (As a minor difference, the acceleration due to gravity is much less variable than the voltage supplied to electrical devices.)

Newtons is force. Joules is energy. Although those bastard units, kWh, calories, and BTU, are also energy.
With gallons/mile, fuel efficiency is linear instead of inverse-linear.
It's equivocation.
Wow, that list is bad. I mean, painfully, horribly bad.

It's a shame metalworking and electronics don't have any applications other than building lightsabers.

If you measure the relative quantities of these, you can get a pretty good idea of the type of chemical an object is made up of.

I was wondering when someone was going to make a nonsense reference to 1984. You'd think Slashdotters had only ever read one book.
Most people have a hard time with Beowulf or Chaucer, though.

Just like how hydrogen stations blow up every day.
