  • I try to do an activity that requires attention, both mentally and physically; for me that’s usually playing guitar, but it could also be cooking, organizing, some kind of craft, whatever. usually what’s keeping me stressed out is thinking about how stressed out I am, so if I can distract myself from that and force myself to think about something else, it breaks the feedback loop, and doing something physical gets some energy out. not sure if it works for everyone, but it often helps me


  • the simple forms of conservation you probably learned in school are not entirely accurate. you probably learned that neither energy not matter can be created or destroyed; whatever you do, the mass you begin with will be the same as the mass you end with, and the same is true, separately, for energy. that’s not actually true; mass can be converted into energy, and vice versa. the correct form of conservation is that the combined mass-energy is constant. mass can be destroyed, but only if a proportional amount of energy is created. the coefficient of that proportionality is the square of the speed of light. that’s what E=mc² means. that’s how nuclear weapons work, and why they’re so powerful. c² is obviously a pretty big value, so when a small amount of matter is destroyed, it creates a large amount of energy

    similarly, energy can be converted into mass, but doing so makes it much “smaller.” c² units of energy will become 1 unit of mass. and mass, of course, interacts with space-time












  • ok I see. my understanding of imperialism is that it encompasses both of those, meaning broadly, expansion of influence, especially (but not necessarily) by claiming areas of land, in order to gain control of resources currently held by others. but I agree, there are two types within that, and the distinction between them is whether the people currently occupying the land (or in particular their labor) are part of the resources that the empire is trying to claim
