    It depends on the atmosphere. On earth, the average ‘size’ of the atmospheric distortion experienced by a photon over 15 miles would far exceed the angular resolution of any pupil-sized aperture. This is a very simple explanation which groups a number of propagation effects broadly under the term “distortion.” Even without atmospheric distortion, there is a limit to the “information” a given aperture can resolve due to purely thermal noise. In theory, if you have an aperture temperature of absolute zero, the thermal resolution is infinite, but also then there is no process by which information can be generated by an I cident photon.










  • And we are going to look back in ten years and realize that a ton of it was big oil misinformation about EV utility.

    Right now, an EV will add around 10 minutes of travel time per 300 miles over an average gas vehicle, and that’s if you are really working hard to minimize stopping time on the ICEV. For most people who can charge at home, this means they will save far more time by not visiting a gas station every two weeks than they will lose on occasional road trips.

    Yet if you go to any discussion on the internet, you will see tons of the same shit where people have this mistaken idea that their one 5+ hour trip per year somehow prevents them from having an EV.







  • Like half the thread, I quit smoking and legitimately feel like it was easy in hindsight. Once I really made up my mind to quit it was not hard. The most difficult part was breaking out of the rituals - smoking in the car, after meals, coffee and a cig…

    Honestly I still end up having one every few years when I’m drinking and it’s kind of nice, but I will never go back to being a smoker. Unless I ended up dating a smoker, which I would avoid. Unless they were like really hot. Or rich. I could totally fix them either way
