  • Yeah, let alone inject it, or try to cure disease with a lightbulb suppository! I'm so glad americans are all rational people, and there's not a significant voting bloc of willfully misinformed dingbats ready to slurp down whatever obvious idiotic lie gets shat out in their general direction by their orange fuhrer!

  • To call the natural process of mutation, literally one of the requirements for any genetic evolutionary progress, "deteriorating" is, at best, short sighted. Most mutations do nothing, most of the ones that do something don't occur in the one sperm that makes it into the ovum, and most of those that do something and make it into the ovum cause an early termination before birth. Some of those that get through all of these hurdles are the ones that cause random genetic variation and increased diversity, without which we actually DO get things like Hemophilia or other sex-linked issues going rampant in any given gene pool. Evolution takes a LONG time to work, but it requires wet and moldable clay to sculpt.

  • I'm sorry, who said Meta was ever the good guy, let alone its shitstain of a CEO? Implementing too-little-too-late consolation fact-checking for a little bit doesn't excuse waving the flag as THE vanguard of misinformation-as-internet-discourse in mainstream social media.

  • fck yea

  • Suppose you are trying to determine the concentration of a solution. You could try to boil off the water and figure out how much solid stuff is left over, but what if it's a mixture, and you just want to know how much, for instance, "Hydrochloric Acid" is in the water. Or, alternatively, some chemicals (such as Hydrochloric acid) evaporate with the water. We need a way to figure out the concentration of this chemical ( we'll call it "Chemical X") without trying to pull it out of the solution.

    So, you need to know how much Chemical X is in your solution, but you can't really easily separate it from the solution. What do you do? You Titrate! You find some other chemical that reacts with Chemical X, so that this new chemical (which we will call Chemical Y) will get instantly destroyed as long as there is still more Chemical X in solution. So, as long as there is more Chemical X in solution, the Chemical Y will get eaten up instantaneously, reacting with Chemical Y.

    Finally, you just need to have some way of detecting whether any Chemical Y exists in the solution, since the moment you see it in solution, you know there's no more Chemical X to eat it up.

    Now, you titrate: take a specific volume of your sample solution, and add a known concentration of Chemical Y, drop by drop. Once there is any chemical Y left over, you know you have found how much Chemical X was in the solution to start. Congratulations, you now know the concentration of Chemical X in the sample solution.

  • I considered that when posting, though the play of prismatic colors which defines the diamond's unique lustre, in addition to that same tendency toward internal reflection, are both ultimately caused by the extraordinary refractory properties of the crystal structure, and the refracted light coming out of the diamond after internal reflection is the constituent of the "shine"

  • As a leftist chemistry teacher, I read it as "having attained union", rather than "not ionized", so YMMV with this heuristic

    ETA: (also, yeah, I have excellent job security until all public schools are abolished in the US)

  • Since an observer traveling through space at the speed of light experiences no time from the beginning of their journey until they decelerate (since their 4-velocity vector has non-zero values only in the 3 dimensions of space), photons don't just arrive precisely when they mean to, from the moment they are emitted, they have already arrived.

  • I mean, you could think of it like rain. Imagine that you have a bucket, and it's out in a rainstorm. There's a plant in the bucket with some soil, and a tiny little pinhole in the bottom that lets out a couple of drips at any given time. Now, let's say you want to make sure that the plant gets just the right amount of water, so that it still gets the right amount of rain, but it doesn't flood and overpower the leak out of the bottom. What's the simplest solution? Figure out how quickly the rain is coming down, and then cover part of the bucket so you only get the right amount of rain, right? Now imagine that some hooligan comes by and decides to muck with your bucket, because for the slightest moment, it will bring their sad, shriveled heart some measure of joy to make your life worse. They decide to move the cover. Maybe they take it off entirely, and that would guarantee the plant would die, but they're a sick, evil little gobshite, so they only move it off when you're out for the day, and then they put it back when you get home. When you go into your house, they take off the cover again, letting in the full torrent of rain. You look at the bucket, and wonder why the plant is getting flooded. Why isn't the cover working anymore? Because it's only there to help some of the time, and the damage that's done while it's missing is piling up faster than the drain can sink it away

    The plant is the entire world ecosystem, you are the careful equilibrium that has been in place since the Oligocene, the rain is sunlight, the cover is arctic ice, the little gobshite is the corporations and individuals that have decided that their personal aggrandizement is the only thing that matters.

    You want real trouble? Now imagine that when the level of water reaches high enough in the bucket, the cover doesn't even fit anymore. That's what happens when the permafrost and methane hydrates release their payloads in the coming years. That way lies the Permian mass extinction.

  • The problem here is that the snow will melt at some point. The reason this is happening is because the sea ice that existed year-round until now is nearly gone each summer. The lack of consistent ice covering means that there is a greater amount of energy being absorbed by the ocean, perhaps not year-round, but that it's happening so much more in the summer is sufficient to utterly outweigh any amount of temporary snowfall anywhere else on the globe.

  • But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government and provide new guards for their future security.
