  ooo, i never thought of using blue tape the way he does, to keep crumbs and shit off a surface i was going to be finishing/sealing later. that’s a good idea

  That makes sense. The specific heat of water is a real bastard to overcome.

  I’m personally skeptical of laser based weapons, given that they have one wavelength. once one is developed and deployed, it will be trivial to paint drones with a reflective paint specific for that wavelength.

  The results is a nation investing 100s of millions on a weapon, that once deployed will be countered by 1000s $ of spray paint.

  imagine if you could get a t-shirt that could deflect a any bullet. that’s what still happen with laser based weapons.

    I think that wouldn’t necessarily work once you get to the right wavelengths for it to start interacting with the organic bases of the paints. There’s only so much you can do when someone shoots an infrared laser at the resonant frequency of a C=C double bond.

      chemist was my weak point at uni. and I’m too tired to look that up, what’s the frequency. I want to check if there are materials that can reflect it.

      the coating doesn’t have to be organic, a thin metallic coating might reflect the laser.

      I’m not giving an expert opinions. but I’m personally betting that any laser weapon will be useless within weeks or days.

      Wasn’t that 1500 whatever-the-unit-was? Below 1000 whatever-the-unit-was was the fingerprint bands, 3400ish whatever-the-unit-was was the O-H bonds, 3100ish whatever-the-unit-was was N-H bonds, 2900ish whatever-the-unit-was was the triple-to-C-H bonds, etc.

      Ugh. The lab portion for that was so tedious. We would have to sketch the expected resonance patterns by hand for a bunch of different molecules. I loved the simplicity of the hydrogen bond nuclear resonance imaging so much more.

        uh, frequency is Hz (hertz) unit to my memory. if that’s what you’re using

        Honestly, I memorised the band once in orgo, and never looked at them again, so you’re more likely to know than I.

      I never knew a disintegration ray was possible.
