    More nerds need to get into philosophy. Specifically CS nerds. I think there’s a tendency, when you get into programming, to start seeing the world in terms of discrete, quantifiable units and categorical rules. It’s a helpful counterbalance to also study something that uses logic to deconstruct that kind of objective physicalist assumption.

      Counterpoint, we get enough of that shit from people writing our design specs, and then give feedback like “it needs to pop more” or “this is good, but we need it to feel more modern”.

      So, discrete, quantifiable things make for an easier deliverable, thanks.

        There’s a quote that I’m having trouble sourcing, but it’s basically:

        Code is for humans to read, and only incidentally for computers to execute.

        I think a lot of things are like that, especially when it comes to defining and organizing work. It’s less about making the perfect requirements document and more about getting everyone to think about a shared goal in a similar way.

        Specifics are great because they make for solid landmarks. But abstract language is essential too, because it clues you into how you ought to navigate the terrain in between those landmarks.

        And there is always space in between the specifics. If you managed to nail down every last detail in your spec, congratulations on your new hand-compiled programming language.

          This is why I like strongly opinionated frameworks! People get hung up on whether they agree with the opinions themselves, which is valid, but I think kinda misses the point. The great strength of opinionated frameworks is the speed with which you can get “everyone to think about a shared goal in a similar way”, to use your phrasing. They do have their problems of course and if you ask me in 5 years, maybe I feel the opposite way about it.

            I also tend to like opinionated frameworks. On top of easing the onboarding process, they can also afford to have more detailed docs/support/stability because they don’t have to account for there being a million ways to do even a basic thing.

            I’m sympathetic, in theory, to the downsides noted by Rich Hickey in Simple Made Easy and Uncle Bob in Architecture The Lost Years… but IRL, I can’t say I’ve ever seen a project successfully lean into those principles at any significant scale. So maybe more of an academic appreciation there.

      I believe individuals choose the worldview that comforts/benefits one the most, and that is why programmers often think in discrete units. It helps them identify issues and handle them well. Is there a reason to introduce discomfort, when the worldview works quite well?

      they would also get that if they learned more math. eventually they tell you that a lot of concrete rules are more like conventions and assumptions that we have collectively decided are “reasonable”. don’t get me wrong, those conventions are still extremely useful. calculus, for example, has made a lot of problems way easier to solve. but it’s not like moses came down from the mountain with the fundamental theorem of calculus etched in stone. you still need to assume things in order to be able to do calculus, and the ways in which calculus is taught and understood has changed a decent amount over the years (infinitesimals to limits, riemann sums to measures, the introduction of differential forms, etc)

        For real. A few times, I’ve been like “What makes you think matter is more fundamentally real than consciousness?” and received an argument that you can measure matter and make mathematical proofs about it.

        And I’m just… dumbfounded by the lack of awareness that they’re essentially using a mere mention of math itself to dismiss the significance of axioms.

          my experience studying math has been that if someone uses the word “mathematical” when they’re trying to argue something, then there is a decent chance they don’t really know what they’re talking about. if they did, they would probably use a more specific term or cite a theorem or proof. math is not a monolith.

          your anecdote is a pretty spectacular example of that. how nice it would be if we could “mathematically prove” that ZFC is objectively true. and also how nice it would be if we could “mathematically define” what it even means for something to be “true” or “objectively true”.

          the incompleteness theorems are a part of this broader point as well, since they basically say we can’t choose a perfect system that has everything we want. but still, the incompleteness theorems themselves require making assumptions. you still need to assume some axioms for them to apply, in addition to picking a set of logical rules to follow. and those logical rules aren’t set in stone either. some mathematicians don’t subscribe to the law or the excluded middle, and it makes for some interesting mathematics. for example, it lets you define an infinitesimal as something that’s basically “not not zero”, while still being different from zero.

      Yep, and that goes for really nebulous things like relationships and mental health too, not just the physical world.

      This sentence hit me:

      seeing the world in terms of discrete, quantifiable units and categorical rules

      I wonder how many past situations I could remember where I had anxiety and panic over not knowing the rules to follow in a situation. But that’s like asking the wrong question if the reality is that there are no rules, and you need more of a guiding philosophy or purpose than a rule book. For me, I think you do what you can to make the unique experience of life things better for yourself and others. We nerds do have a tendency to focus on “number go up” which has its benefits, but has to be in moderation as with everything else.

    Remember kids that you don’t feel matter; you feel the electrostatic repulsion of electrons that occupy part of the 99+% of empty space of each atom is composed of. The vibrational frequency of those atoms create heat that radiates through that void to be detected by other atoms as more or less heat energy. Over 99% of you is empty space and radiant energy, which means that mathematically you barely even exist.

    “Because you have to wonder: how do the machines know what Tasty Wheat tasted like? Maybe they got it wrong. Maybe what I think Tasty Wheat tasted like actually tasted like oatmeal, or tuna fish.

    nothing is real do what you want

    That is a fallacious conclusion from this observation. Don’t use this philosophy as an excuse to act like an asshole.

    While everyone perceives reality slightly differently, apples do have a specific light absorption and reflection spectrum.

    Our limited perception of it doesn’t make it “not real”. Same is true for other senses as well.

        In the assumption that you are real, because you think and therefor you must exist in some form, but have limited control of your perceived reality through your actions, you should make choices that maximize your satisfaction but your longterm satisfaction is actually dependent on not being an asshole.

        Therefor, our lack of provable existence does not factor into whether you should or should not be an asshole.

        Fluorine (9 protons)

        • A highly reactive, poisonous, pale yellow gas
        • One of the most electronegative elements
        • Forms strong chemical bonds and reacts violently with many substances
        • Highly dangerous and corrosive

        Neon (10 protons)

        • An inert noble gas
        • Completely non-reactive
        • Safe and stable
        • Used in lighting and signs due to its stability

        That’s not just perception. Same with chlorine/argon. Etc. These chemicals would have different characteristics that react very differently with the chemicals around them even if we weren’t here to identify the differences.

          Nah dude, they’re basically the same thing. Both have a composition of protons/neutrons, both undergo a phase change to a plasma state at incredibly low temperatures, both interact with other atoms via the fundemental forces, both can (hypothetically, we can’t actually fuse anything above boron for complicated reasons I’ll pretend I remember) form one another via fusion, both are actually composites formed from tossing the fundemental particles in a blender, etc.

          The differences we see are, when considered within the scope of all the possible arrangements of particles and forces we could have gotten, impossibly minor.

            Look, I agree with everything you said, at the most fundamental level, they’re just different arrangements of the same cosmic lego pieces. But I think that’s exactly what makes their differences so fascinating. The fact that one extra proton, a particle so tiny we can barely comprehend its scale at ~1.67x10^-27kg, can transform a violently reactive gas into something completely inert is mind blowing.

            It’s like saying a single base pair mutation in DNA and the original sequence are “basically the same thing” because they’re both just nucleotides in a chain. Sure, you’re technically correct, but that tiny change can cascade into dramatically different proteins, cellular behaviors, and ultimately entire phenotypes.

            The beauty is in how these tiny quantum differences cascade up into the macro world. One proton’s difference doesn’t just change numbers on a page - it’s the difference between neon lighting up our cities and fluorine eating through your lungs. Their atomic radii differ significantly, their electron configurations lead to completely different bonding behaviors, their ionization energies vary markedly, and they even interact with electromagnetic radiation in distinct ways, absorbing and emitting entirely different wavelengths of light. All because of having 1 more of something 0.84 femtometers across. That’s crazy.

              Damn, you’re really good at identifying miniscule differences!

              Seriously though, I was attempting to highlight how truly unremarkable these changes are when viewed from a grand enough scale. That’s not to say I dont understand, I do, and nuclear/particle physics are fields absolutely filled to the brim with things worth waxing poetic about. And when viewed from a field that deals with meta-analysis of physical laws themselves, the differences that people are excited for start to appear… pretty mundane. Every person on earth is similar yet different, but we all avoid that guy who shares his life story at the drop of a hat because, to (badly) paraphrase Syndrome, “once everything is unique, nothing is.”

              The nihilist vs. absurdist meme is popular now and does seem to serve this example well - It’s not that these changes dont matter or aren’t cool, it’s that nothing matters and probably everything is arbitrary, and that is in of itself cool! It raises so many unanswered questions that string theorists would love to tell you the answers to but no! I cast you out, you and your vile “branes”! Back! Back in your caves you slime beasts! We shall not treat your physics fanfic this day! that we just don’t even have guesses as to what could maybe possibly be the answers yet! Hell, we’re not even sure the holographic universe theory is right, but more than half the physics community is convinced enough to get published in Nature while assuming it.

              There’s so much wild stuff being discovered right now, I guess it’s just sad to see people hung up on physical properties that were largely solved more than 50 years ago.

    To make it even crazier while we think of color blindness as a binary thing, it’s really (like most things) a spectrum.

    Everyone has a slightly different ratio of cones. And some have a different amount of cones than others. Then there’s the ratio of the different comes to rods.

    Take any two random people and they’ll likely agree what name a color is, but they both experience that color slightly differently.

        Yeah, I should have said:

        And some have a different amount of types cones than others. Then there’s the ratio of the different comes to rods.

        But it’s not really like there’s distinct type of cones, it’s about the wavelength the cones capture based on the angle of the cone.

        So while normally theyre: long, medium, or short

        They can also be at any point on that scale, and even so far that they’re essentially a new type of cone

        But every cone is going to be a little different based on its exact shape and everyone has different ratios. Think of it like snowflakes.

        If you measure exact enough, no two people will experience the same color, and you don’t even between your two eyes. It’s just very unlikely to be a noticable difference, and our brains like to do “post processing” stuff to make it similar.

      The longest standing argument between myself and my family is about the color of my mother’s very 1950’s bathroom.

      They say it’s battleship grey.

      They’re wrong. The tile and most of the fixtures are a dull, dusty light blue. Only the marble around the sink is a true grey color, which is why it looks so obviously out of place. The room gives me fits and no one else can see it.

    Shrimp have multiple color recptors because their brains are too primitive/rudimentary to combine input from more than a single receptor into a composite color. The result is that 12 colors (or however many receptors it is) is the total number of colors they can see.

      Just the span of wavelengths isn’t the only thing that’s important, the spectral resolution is also important. For example, theoretically with 6 different cones we would be able to tell the difference between the mixture of red and green wavelengths vs only seeing yellow wavelengths.

      Or the mixture of blue and red wavelengths vs violet wavelengths, which just happen to be at the furthest possible point from the red wavelengths. Human color perception is strange.

    Physicists: spend hundreds of generations empirically proving objective science

    Philosophers: yeah, well, that’s just like your opinion, man

      Philosophers: It is what it is.

      Physicians: We need to be a bit more specific than that. Can we measure it?

        Physicist: Who invited the medical doctor? He seems far too invested in applied physics! Who is next, a (retches) engineer?

      Fancy words for “there’s something and there’s nothing”. So, yes.

      I have come to think of it as all being probability fields.

      When studying a particle, one cannot know both the energy and position of that particle with certainty (Heisenberg’s Uncertainty Principle). When chemists think about the 3d “structure” of atoms and molecules, they represent the nucleus as a tiny little ball and the electrons as bubbles of probability: Atomic Orbitals Example (Hydrogen).

      The nucleus itself is in constant motion as well, and compared to the size of the actual protons and neutrons, there is much more empty space - kind of like planets in a solar system. And each of these protons/neutrons is composed of tiny particles called quarks, which again are in constant motion and thus make up probability fields that we call protons and neutrons.

      Yes, it’s where Janets go when they’ve not been summoned.

      And that one time when she had to hide those people.
