Angular resolution through the Atmosphere has been solved with adaptive optics and advanced mathematical techniques. Unfortunately, nothing can remove the temperature of the atmosphere (which affects infrared imaging), or the absorption of

Only maybe in the dense core of a galaxy because incident radiation falls off with the square of distance. The nearest star to us after the Sun is ~4ly away, or ~250k AU. The Sun would have to be ~63 billion times brighter to give the sam

Nobody who had to work with 6509's/7609's at an ISP is shedding a tear over this. Someone (Richard Steenbergen?) once made a joke that we should take the last 6509/7609 and launch it into orbit to celebrate. It's no

I remember Hale-Bopp in 1997. At it's peak it was so bright you could easily see it from inside a brightly lit restaurant, looking out a window 20 feet away.

I just had an idea that may be my worst technology idea ever. Assemble some unstable atoms (that decay into carbon) into the desired cubic structure. When they decay you have a diamond. The problem with this is that if it can decay fast eno

I did indeed mean a singe, byte-valued parameter indicating angle (similar to the single angle parameter of a mechanical polarizing filter) Full polarization and phase info would be great to have also but probably not necessary for reflecti

What we need is sensors that can scan polarization on a per-pixel basis (like 256 orientations per pixel per image. Then it would be much easier to detect and remove consistently polarized components of the image (as specular reflections fr

I have a personal theory about human intuition. It feels like answers come "from outer space" or "from God" but it's really just a highly optimized and efficient part of the brain for a very specific function. For t
