Being a precise base ten integer suggests it is human derived. 982.000 MHz is the second harmonic of 491.000 MHz, which is the center of Channel 17, UHF Television. It is probably the local oscillator of a broadcast TV tower. Harmonics can

Simply replacing gas stations with chargers is a step back in electric's flexiblity. They don't need large underground storage tanks and special zoning. I think gas stations will simply vanish, and chargers will stay next to usefu

I think you have to look at the joint distribution with Alaska included to draw any conclusions. Just looking at separate marginals will be uninformative.

I'd argue negative correlation on conditionals distributions can be reasonable here. In that particular WA-MS example, if Trump suddenly took more liberal positions and somehow won WA (e.g., announces he's pro abortion), he would

That's a very interesting observation about what you're looking for in a car. The laggy slow acceleration of a Prius--while smooth--really bothers me, but I could imagine some seeing it as a plus. For me, in a Prius I feel unabl

Do the satellites impact more than a single pixel at a time for a brief moment? Can't the normal image stacking and pixel masking resolve this? Seems like a bigger threat to astronomy is clouds.

Another example would be forward error correction (adding parity bits to improve robustness at the expense of efficiency). But inefficiency isn't necessarally more robust unless the extra bits serve some purpose.
