  • If we can reduce the shockwave from sonic booms that could directly lead to more efficient plane engines. The main current impediment they have is the tips of the turbine blades can only get so close to the speed of sound before they explode from the forces they’re experiencing.

    Which could have knock-on effects for anything involving an airfoil moving through a fluid. Helicopters, boats, wind turbines, hydro-power, etc.

    Better understanding and control of the physics / materials science at the sound barrier would be very good news.







  • The Honeywell ones are nice and simple and have instructions for whichever number of wires you already have. With stickers for easy labeling as your removing the old one. They have a few models for whichever network you prefer.

    The different wires can be intimidating, but they’re all standard colors. And your dumb thermostat is already wired with everything you need. The smart one mostly just adds a radio.

    The wires are basically: power to the thermostat, ground, and a number of different signal wires for “AC on”, “furnace on”, etc that when the respective wire gets 5v(?) that device turns on.

    Thermostats are very simple devices that just regulate when the high voltage devices should turn on. Things do get a bit more complicated if you have a bigger house with multiple HVAC zones and stuff but most people don’t have those. And even if you do, that’s mostly just more wires to connect that will already be there.







  • They’re joking, but most of the US are “Right to Work” states. Meaning, on paper, you have the ‘right’ to quit your job without reprisal, but in practice the company can fire you without compensation. They owe for anything you’ve already done, but that’s about it.

    I was thinking their package was pretty generous but you’re right it’s very basic for other places.





  • We are only ‘pretty sure’ of the mechanism of how Tylenol works biochemically as of 2025.

    You can test for effectiveness and dangers and everything else you need to prescribe something to get a good idea of whether its actually doing something or not.

    ‘Alternative medicine’ is largely, “I felt better after a bit”.
