  • I think people kind of ruined entropy with all that disorder crap. The simple conceptual explanation is that entropy represents the energy that is unavailable to do work. The more entropy a system has the less work it’s capable of doing, which ultimately means the less can happen within that system. Entropy always increases globally, because anything you do is something that happens and anything that happens means less energy available to make other things happen. The complex esoteric interpretations might have some conceptual value in specific circumstances, but like a lot of science communication the rigorous scientific definitions don’t get communicated, so now we have nebulous concepts like order and disorder floating around that just confuse people more than anything.


  • As an engineer this is a comically incorrect take. Absolute zero is useful as an absolute reference in the same way zero of anything is. Try doing anything more complex than high school physics and the practical necessity for an absolute temperature reference becomes obvious. For fucks sake they even bothered to make an imperial version. Rankine is just Fahrenheit shifted to have zero be absolute.








  • Fire is a natural and necessary part of many ecosystemsm. It keeps parasitic insect populations down, stuff like ticks and chiggers, and some plant species rely on fire to prepare the soil for seeds and even is required for some plants to release their seeds. In dry ecosystems like the western USA it also consumes old dead plant material, reducing the fuel available for future fires and reducing fire severity overall. Many foresters and fire fighters advocate for increasing prescribed burns, essentially forest fires that we light on purpose in cooler and wetter times of the year to consume the fuel without risking a catastrophic fire that is difficult to control. I just think that’s neat.





  • I’d just like to say this is categorically false advertising if there isn’t an actual hat inside. If they included extra foil for the hat the amount listed on the box would be incorrect. If they didn’t include extra foil, or the label said the correct amount of foil, then there’s no free hat. Those are completely mutually exclusive cases, so if there’s no hat, easy false advertising lawsuit. You deserve the free hat they said you were getting.
