  • 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.






  • Quantum mechanics works, no doubt about it. What I seriously doubt is the interpretation of what it means. When you get right down to it, it’s just our best most successful attempt to model physical systems we can’t observe with enough detail to tell exactly what’s happening. The whole uncertainty principle isn’t some magic truth about the nature of reality, it’s just a statement about measuring particles by bumping them with other particles. Wave particle duality is an interpretation of the math, it isn’t required for the math to work. Bell “disproved” hidden variable theories and we’ve been working with our hands tied behind our backs ever since, just so we can preserve the comforting fiction that have free will or that it means anything in the first place. It honestly pisses me off because so many scientists just accept the Copenhagen interpretation as truth, to the point that it’s become dogma and anyone suggesting otherwise is automatically wrong. It’s no wonder particle physics has hardly made any progress in the last few decades.


  • I understand why people always say things like this. It’s the not having a choice that ruins eternity. Fortunately it seems that such a fate is physically impossible in this reality. Even if you were made of the most durable possible material, you would still fundamentally be composed of baryonic matter, which means if you fell into a star, collided with a celestial object at relativistic speed, or fell into a black hole, you would surely die. There is always a way out for an enterprising immortal, and afterwards sweet nothing.


  • This is kind of a shit metaphor because if we extend it to how piracy actually works it highlights how stupid DRM is in the first place. A lock on your house has to be picked by each individual robber, unless they all show up on the same day. A cracked game would be like if only one person has to pick the lock on your house, but they don’t actually take anything they just make a perfect copy of your house without the draconian 12 step lock you installed and gives copies to whoever wants one. If you never noticed all the people sharing magical copies of your house with each other you would never know you lost anything, because you didn’t. Only your blind greed was injured by the thought that those people might have been willing to pay to use your house if only it had been locked down against those damn house copiers. On your next house you make the locks even more invasive and complex, to the point they block half the driveway or make the oven and bathroom unusable. Then that same one person spends an extra half day to pick it and makes a copy but without the crazy lock so they actually get a better house than you’re selling. Whether people like it or not, digital media has always been on the honor system, and always will be. DRM just punishes people for doing the honorable thing and paying.








  • 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.
