The free space path loss from Earth to Alpha Centauri (4.4 ly) is ~345 dB at 100 MHz (FM broadcast). Our broadcast signals, with their relatively non-directional radiation patterns, are well below the thermal noise floor long before they re

Consider the standard long division algorithm. Would you rather students become fast and accurate in applying it or would you rather students have the skills to understand what's going on and derive it for themselves? Drilling will cer

It's not a matter of geography. It's a matter of language. In English, a period acts as the radix point and a comma acts as a separator. It's a common error for people who learned English as a second language to use the conve

You never vary aperture when taking bracketed exposures to merge to HDR. The depth of field would vary from exposure to exposure, making things inconsistent when you merge them. It's shutter speed you vary. My point is that with 2005-e

My experience has been that you can almost always find decent three star hotels at normal rates for under 125-150% of the GSA published rate. The exceptions tend to be when there's a major event that causes exceptional demand.

Silicon imagers don't work very well past 1 µm or so. To go out to 1.2 µm, you're using another semiconductor and that gets expensive rather quickly.

It's sad to see that they've harmed accessibility (no more transcripts) under some misguided notion that it helps keep secrets. The video of these talks is still available, of course. Maybe it's captioned?
