  • I trawled through your profile a bit, enough to see that you’re reasonably well meaning, but both steeped in biased propaganda and having issues from the many broken systems in the US.

    My question however is how you believe that Trump will make your life better?

    From my perspective (from Europe), you’re exactly the type of person Trump loves grifting off of. Last time he did a lot of killing off lower middle class jobs, plundering your workers rights, protections and wages, mismanaging or dismantling support systems like healthcare, infrastructure, disaster readiness, while also increasing taxes on you. Oh, and also bumbled through the pandemic and disaster responses causing more than a million unnecessary deaths.

    He also openly broke the law, got very questionable payments coinciding with odd policy changes, and leaked/sold national secrets not only betraying the institutions, but the nation itself.

    He’s also a known adulterer, liar, slanderer, prideful cheat.

    So that would seem to disqualify him as a good pick for either policy, statesmanship, patriotism, or moral reasons.

    The only remaining reason then seems to be feelings, no?

    Feel free to tell me what Trump does better than Biden, for your life and/or for the nation, or whatever other perspective is more important for you.


  • Heat is electromagnetic radiation - photons, sound is mechanical displacement - phonons.

    They mostly propagate the same due to being waves, in most other respects they are very different.

    Heat convection is an entirely separate process where heat radiation is aided by the movement of the surrounding medium. Where it would otherwise heat up it’s environment, convection keeps the environment from heating up. Compare coffee in a thermos (very little convection) to a cup you’re blowing on (significant convection); more air movement - more cooling.

    Also, destructive interference does not at all work like that.

    Maybe a more useful analogy could be that waves have like walking animations, where in part of the animation they go up, and in another part they go down. Destructive interference happens when a wave in its’ “up” phase crosses a wave in it’s “down”, meaning the resulting movement looks like nothing. The waves don’t however interact in any way, and will continue on their way and on their own animation cycles.

    The shifting and heating parts are technically true but require very specific circumstances, enough so that I’m more prone to believe it’s another misunderstanding of the physics behind this. But I’ll give you the benefit of the doubt.


  • Covid had plenty of travel restrictions, took less than a week to set them up. There’s already issue with people being falsely flagged as terrorist or other no-flight risk, and with some of the anti-leftist rhetoric it’s not a big leap to make. Also it’s entirely in line with Russia labelling LGBT as terrorists, which several GOP/MAGAts are breathing heavily over.

    I hope you’re right, I just don’t see anything but decorum stopping them, and they’ve repeatedly thrown that out the window.









  • @toboggonablaze is essentially correct, but let me try explain it in a slightly different way.

    Lasers do a bunch of things to basically shoot a stream of photons at something. There’s basically two ways you can affect how much energy comes out of a laser, you can make the stream denser (more photons per second) - called intensity, or you can increase the energy in each photon.

    The weird part about photon energy is that higher energy photons are of a different “color”, where red is lower than green, is lower than blue, is lower than gamma rays, etc.

    So changing the color of a laser already means you’ve changed how much energy it can output.

    Then there’s another part of your question: how lead gets heated up. Different materials respond differently to different types/wavelengths of light, an example you might be familiar with is that glass panes let through visible light, but not the heat from the sun, or that water also is see through, but can easily be microwaved (by microwaves - low frequency light).

    Basically, a material can be more or less “translucent” in certain frequencies. I’d like to look lead up for you, but Google isn’t cooperating today. But basically, there are frequencies that lead will be more and less susceptible to.

    That’s probably not what you meant with the question, but if that’s the application you want to use the laser for, you might want to take it into consideration.

    So, in summary: color is energy, intensity is energy, you can change both independently, so your question doesn’t quite make sense.

    Also, different targets will heat differently, also not making it a fair comparison.
