    and then some bozo says that biology is just complicated chemistry and chemistry is just complicated physics and we can simulate physics

    curious thing is that i never hear biologists or chemists saying that, only some physicists and techbros. just trying to simulate your way out of small organic chemistry problems will make you even more hopelessly lost than you were before

      As a (micro)biologist, I totally support that notion. Biology is, indeed, chemistry, which is in turn physics, which is in turn mathematics.

      The problem is, good freaking luck simulating biological processes on a physical level. We do biology and not physics, because it’s a reasonable shortcut we have to make to work on what’s important without waiting another millenia for a decent enough physical simulation.

            That’s the thing: we do a bit of everything. I work in the development department for a very small city with a LOT of complicated development. We have a dozen employees for the wholencity, so having a wide skillset is necessary as I wear a lot of hats.

            I am the GIS department, half the Planning department, lanning, and code enforcement. I analyze stormwater discharge, review rainwater harvesting water treatment plans, Dark Sky compliance, and other plan review I’m needed for.

            If I have to get too deep into complicated engineering, construction code, or legal issues, I coordinate all third-party review services. I also handle any interlocal development-related issues (county and state compliance and water, fire, and school district).

            I also act as the recording secretary for most public meetings, handle non-police Open Records, and run the city website.

            I’m always stressed and super busy, but I’m also someone who thrives on spinning plates and chasing squirrels versus being bored doing the same thing day to day.

    A Story About ‘Magic’, from ESR’s “Jargon File”

    Some years ago, I (GLS) was snooping around in the cabinets that housed the MIT AI Lab’s PDP-10, and noticed a little switch glued to the frame of one cabinet. It was obviously a homebrew job, added by one of the lab’s hardware hackers (no one knows who).

    You don’t touch an unknown switch on a computer without knowing what it does, because you might crash the computer. The switch was labeled in a most unhelpful way. It had two positions, and scrawled in pencil on the metal switch body were the words ‘magic’ and ‘more magic’. The switch was in the ‘more magic’ position.

    I called another hacker over to look at it. He had never seen the switch before either. Closer examination revealed that the switch had only one wire running to it! The other end of the wire did disappear into the maze of wires inside the computer, but it’s a basic fact of electricity that a switch can’t do anything unless there are two wires connected to it. This switch had a wire connected on one side and no wire on its other side.

    It was clear that this switch was someone’s idea of a silly joke. Convinced by our reasoning that the switch was inoperative, we flipped it. The computer instantly crashed.

    Imagine our utter astonishment. We wrote it off as coincidence, but nevertheless restored the switch to the ‘more magic’ position before reviving the computer.

    A year later, I told this story to yet another hacker, David Moon as I recall. He clearly doubted my sanity, or suspected me of a supernatural belief in the power of this switch, or perhaps thought I was fooling him with a bogus saga. To prove it to him, I showed him the very switch, still glued to the cabinet frame with only one wire connected to it, still in the ‘more magic’ position. We scrutinized the switch and its lone connection, and found that the other end of the wire, though connected to the computer wiring, was connected to a ground pin. That clearly made the switch doubly useless: not only was it electrically nonoperative, but it was connected to a place that couldn’t affect anything anyway. So we flipped the switch.

    The computer promptly crashed.

    This time we ran for Richard Greenblatt, a long-time MIT hacker, who was close at hand. He had never noticed the switch before, either. He inspected it, concluded it was useless, got some diagonal cutters and diked it out. We then revived the computer and it has run fine ever since.

    We still don’t know how the switch crashed the machine. There is a theory that some circuit near the ground pin was marginal, and flipping the switch changed the electrical capacitance enough to upset the circuit as millionth-of-a-second pulses went through it. But we’ll never know for sure; all we can really say is that the switch was magic.

    I still have that switch in my basement. Maybe I’m silly, but I usually keep it set on ‘more magic’.

    1994: Another explanation of this story has since been offered. Note that the switch body was metal. Suppose that the non-connected side of the switch was connected to the switch body (usually the body is connected to a separate earth lug, but there are exceptions). The body is connected to the computer case, which is, presumably, grounded. Now the circuit ground within the machine isn’t necessarily at the same potential as the case ground, so flipping the switch connected the circuit ground to the case ground, causing a voltage drop/jump which reset the machine. This was probably discovered by someone who found out the hard way that there was a potential difference between the two, and who then wired in the switch as a joke.

      reminds me of this copypasta

      As someone who works on a big robotic mingun for the Navy you would not BELIEVE how close to home the Adeptus Mechanicus hits for me. For starters we have written procures that need to be followed to the letter like a ritual and deviating from it at all, especially during a spot check can get you in serious trouble… Technicians are also really goddamned superstitious and for good reason. If you accidentally cut yourself on the equipment, it will start to work as if it’s accepted your blood sacrifice. The mounts also all have names and their own personalities. If you do anything that displeases the machine spirit’s they will not work. My favorite story I was told by one of my instructors in school was the time a bunch of Aegis techs sacrificed a live chicken to their their radar and sealed its bones inside a metal box and attached it to the radar console, after which it started working flawlessly. That is until the CO came by and saw this box stuck to it and ordered it be taken down. THE MOMENT it was taken down, the radar cut off and REFUSED to work. After countless man hours of troubleshooting this thing and finding nothing wrong, they have to fly a tech rep out to figure out what the hells the matter with this thing. They tell him what happened and his response? He puts the box back on the console becuase he knows what sort of black magic runs this equipment and lo and behold it starts working again. Whoever originally made the Machine Cult got it spot on what kind of culture a bunch of technicians would develop if left on their own for a millenia

        Tom Knight and the Lisp Machine

        A novice was trying to fix a broken Lisp machine by turning the power off and on.
        Knight, seeing what the student was doing, spoke sternly: “You cannot fix a machine by just power-cycling it with no understanding of what is going wrong.”
        Knight turned the machine off and on.
        The machine worked.

      Is lab grade distilled water more guaranteed to be neutral pH? Because I tested some random distilled water from walmart and it was like 5.5. I then went down a rabbit hole and learned that distilled water is so pure that it just sucks up carbon from the air.

        it will vary, just after distillation (or RO/ion exchange) it should be closer to 7 then it goes down as carbon dioxide gets absorbed. that’s why it’s buffered everywhere where it matters

        Not only the CO2, but also the glassware you put the water in for measuring can very significantly alter the pH. Some scientists I know systematically screened different, presumably clean, containers because of this effect before progressing with their experiments.

        i remember reading recently that it was discovered that a lot of studies regarding microplastics are likely wrong. because nitrile gloves used to operate in the laboratory gives off microplastics, so there is basically no uncontaminated samples.

            Of all of the Apollo astronauts only one was a scientist.

            Out of the entirety of the Apollo missions we got one scientist on the moon. It’s pretty clear whether US governments intentions lay.

              Apollo, yes. I don’t think it’s for reasons you might be implying (what are they, that they’re going to space to kill stuff?). They have to have people who can endure high-gs and stress. Pilots are already proven for this. A civilian they have to test and train up from nothing. I don’t think it’s some kind of secret military plot. It’s just convenience and accessibility.

          That’s an interesting take. I worked in a pharma startup once and they were grinding cutthroat bitches, but yeah, they were very focused on what they wanted to achieve. The most unethical thing - apart from absolutely ignoring human decency and worker’s rights - was probably exploiting funding for Covid research for cancer research. To be fair tho, it was the early days of Covid and their initial cancer target was structurally similar to a molecule in sars cov 2. And the CEO slept like 3 hours a day and was always one of the first ones to turn in applications for some funding contest, which is why he often got them. You have to get the money for your work somehow. And we did use the money for the development of the covid drug, it is just that we also used it to run the same tests and get equipment/reagents for the cancer targets.
