      When I find a solvent on pubchem that has the taste characterized by some mad lad from the 1800s, it makes me want to try it.

      You say THF is spicy water? Now I’m curious. We must confirm this claim.

      I hear ether smells good. We must confirm this claim.

      These fancy new box cutters are safe and cannot cut your hand. We must confirm this claim.

      Like, so what if we store our tBuLi with other low-flash point flammables? And pyrophoric oxidizers? In the same bin? That’s stuck in a block of ice in the 30-year-old freezer because it hasn’t ever been de-iced?

      What if the power goes out for a long period of time and the tBuLi goes for a swim? Or we say you have to de-ice the freezer?

      Haha sounds crazy. And, I wouldn’t have to do the shitty quench before disposal. Or work on that project anymore.

      Because you’re injured or because PI fires you?

      Haha, yeah :)

      Oh, while you’re here, does this still smell like DCM? I can’t tell if I rotavapped it all off and the NMR tubes all need aqua regia (sorry my b).

        That’s just bad management and you shouldn’t store tBuLi that long anyway because it’ll decompose. You shouldn’t put it in freezer either

        Oh, while you’re here, does this still smell like DCM? I can’t tell if I rotavapped it all off and the NMR tubes all need aqua regia (sorry my b).

        just put it on high vacuum

        What are you working with that requires aqua regia to clean NMR tubes? I’ve only had to use piranha once in a decade, while cleaning things that acetone, DCM, and basic ethanol won’t touch, and this was just after moving to another lab

          Yes. The whole thing is satirizing the “Safety -> Against” bit. Each piece, though exaggerated for effect, has a basis in something I’ve seen over the years.

          Regarding NMR tubes though, the answer in my old group was precious metal complexes, which have a tendency to mirror out once they’ve done their bit. Or just existed for too long; a lot of them were touchy. The mirror tends to resist solvents and scrubbing. Nitric acid alone sometimes was enough to remove it depending on the metal, but often not. At some point the cost, effort, and danger are all supposed to outweigh just binning the lot and buying new tubes, but my PI was allergic to buying new things.

        Aqua regia isn’t even that scary. Try pipetting pure bromine while it shoots itself out from constantly evaporating

          Aqua regia ain’t no piranha, and also ain’t the most concerning thing in my post lol.

          Ah bromine. Super dense, low MW, and low bp, all making dosing accurate amounts a heroic feat. If you store your bromine cold, you can precool the pipette by sucking up and spitting out a few times before transfering, which helps cut down the vapor.

      Yeah but what if we imagine it’s real and convince everyone to believe it too. Surely nothing will go wrong!

      Of course a hexbear tankie would think that. Sincerely hope you’re joking, but maybe I shouldn’t hope to not get severely disappointed.

          Which is why it’s explained in economic courses beyond your baseless ideas that there are better models to calculate standards of living than GDP. But you’d never know that. Because you know nothing of economics.

          Did you know that’s just one possible economic model in the field of economics?

          • If you follow the flowchart and dive into most economics departments you will encounter what I’m talking about.

            What are you talking about Keynesian liberals or something? I do like to read Adam Tooze to see him close in on an interesting point only to veer wildly. Foreign Policy in general has some interesting writers if you want to mine the most advanced liberal cope.

            The model of economics I’m describing is the one which has been most heavily promoted by the west, neoliberalism, it has been used to dissolve the social welfare state which was set up to compete with the socialist bloc since defeating its chief rival and counterbalance in the USSR. It’s an ideological persuasion that works along with coercion and subterfuge to eliminate capital controls and suppress the masses with starvation and crackdowns, especially in peripheral countries which are starting to establish socialistic policies or nationalize natural resources. Look at Chile for a perfect example of liberal economics in practice.

            I am aware of plenty of different non-Marxist models of economics and none of them are great because they treat various sectors of production wrong. China and Vietnam have their shit all figured out that’s why finance capital and food aid can’t decimate their agricultural production and then extort them into unfavorable IMF deals.

      Economics just means studying how we distribute limited goods. It breaks down when goods aren’t limited (or rather, we have more of it than we can reasonably use), but we’re not quite at that level of post-scarcity for most things. Though we might be close enough to cover the first level of Maslow’s Hierarchy of Needs.

      Economics as a practical discipline tends to assume capitalism. Economics can still be valid without assuming capitalism. There are tons of non-capitalist modes of distributing limited goods.

          You’re confusing the study of economics with specific economic ideologies. Clearly you’ve never studied the subject and are very much biased.

          • I’ve studied economics as a discipline too much not to acknowledge its institutional biases. The statement “economics isn’t real bro” is a joke, but it’s a joke about how bad the state of the academy is in promoting neoliberal economics.

            If that weren’t true it wouldn’t be powerful enough to turn Argentina into a fourth world nation. Milei is a product of these academic institutions.

            If you actually went to or taught at a university that eludes these biases like the Braudel fans at Binghampton, you wouldn’t be scolding me for making a joke about how stupid most economics degrees render people.

    There could be one more to differentiate engineers from architects. Do you like to solve problems (engineer) or create them (architect)? Fun flowchart!
