  • There are 2 parts at work. The focus reflex and the blink reflex. The window between them is the dangerous part. If the pulse is fast enough ( a few ms) then the eye can’t focus, and it’s fairly safe (unless you were already focused on the emitter). If the pulse is low enough power then the blink reflex kicks in and protects your eye.

    Hitting a mosquito is a hard task, tracking one is even harder. It’s better to use an ultra short pulse, with a bit more power. You can also shift the frequency. If it’s an infrared laser then the eye won’t lock onto it, and will struggle to focus it dangerously.





  • A lot of the big building companies, in Europe, treat solar panels as a premium option and so charge a larger profit margin on them. Installing solar, while constructing the house is a LOT cheaper and easier than retrofitting them later.

    The panels have gotten cheap enough that it’s no longer a real cost burden, Vs the cost of the house.









  • Not even playing lip service to supporting the open source stuff they built upon. They’ve also recently been trying to lockdown and paywall (or just drop) features. Including legal action against people trying to undo the damage.

    The general sniff test is they are trying to lock people in before milking them for all they can.




  • QM isn’t insane to understand. It’s main issue is that it doesn’t map well/at all to our normal experience. You need to dive into the maths, and accept what falls out.

    The main deeper level here is how the blurring happens. The photons explore all possible paths. The result is an integral of them all. In general, vast areas cancel out, leaving classical (ish) behaviour. This makes sense mathematically, but has no classical analogy to compare to.


  • It’s quantum mechanical, so the maths gets complex. It can be simplified in a useful way however.

    Basically, atoms can absorb photons and then re-emit them. You can think of the photon flying past at C, but getting absorbed and emitted along the way, adding delays. In QM however, neat particles don’t exist, it deals with quantised, probabilistic waves. The above effect gets blurred over the waveform. No one atom definitely absorbs it or doesn’t, it gets blurred together into a general slowing of the wavefront.
