    Anybody else try to memorize the chemical elements? Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium. That’s as far as I ever got, the metals were too confusing.

    Kids love trivia. When I was a kid I had the characteristics of dozens of dinosaur species memorized. The whole Pokemon franchise is built on this.

      sqrt 2 = 1.4142135623730950884
      sqrt 3 = 1.732050808
      sqrt 5 = 2.236067978
      sqrt 6 = 2.664(?) i think
      sqrt 7 = ?
      sqrt 8 = 2.828
      sqrt 10 = 3.166

      recited from memory, remembered since i was 13 or sth idk, i was bored back then.

        At one time I knew pi to thirty places. Then I read somewhere that it really doesn’t need to be that precise. So for example, if you were measuring the circumference of the earth using π = 3.14159 vs π = 3.141592653589793 it only changes the circumference by fractions of a millimeter at this scale. I can’t measure a 24 inch piece of wood with that amount of accuracy.

          The circumference of the Earth is somewhat subjective at that scale anyway, since it also depends on where you decide the radius stops.

            Well yeah since we really aren’t a perfect sphere. Not to mention elevation, buildings, etc.

        Alpha Beta Gamma Delta Epsilon Zeta Eta Theta Iota Kappa Lambda Mu Nu Omicron? ? Rho Tau Sigma Upsilon Phi Chi Psi Omega

        Edit: Forgot about Xi and Pi, before and after Omicron respectively. Also swapped Tau and Sigma’s position.

    My grandpa (electrician) was telling me about electrons. I was so fascinated with things like current not being speed, and magnetic force, and batteries. I think I’ve learned now everything there is to learn about electrons - electronics, electrochemistry, magnetooptics, electron microscopy, positron tomography, xray generation, power generation, electrites, etc, etc.

    Still unemployed lol.

      Damnit, this is why the world needs some sort of universal basic income system. You might be the one to create effectively free energy or something but we’ll never know.

        I’ve done my share of science magic; and I’ll probably do more, I don’t need some state capitalists’ approval or anything for that. Would be nice if they just go to hell nicely and never bother me when I try to trade whatever I make with my community.

      there’s 2 types of electric current: electrons flowing through a wire, and protons flowing through water

      the second kind is also called a pH gradient (because pH value measures how many protons there are in water) and is the main theme of most of biochemistry. since biochemistry is all about moving protons (and other charged ions) around. so this opens up a whole new field (biochemistry) for you!

        Also, to be honest, there are way more forms of electric current. There is plasma conductivity, superconducting pairs dynamics, molecular conductivity through coupled orbitals, quasiparticle conductivity and other weirdness of solid state (Hall effect shows whether it’s electrons or holes where electrons are missing are charge carriers, for example). World is beautiful.

      Heh, I’m an electron microscopist. Also, ham radio operator. ‘Electricity’ is fascinating.

    Kids just want attention and love from their parents. They’ll take interest in your interests if you share them with them.

    I tried to bore my son to sleep by reading Dune to him. He now reads the books on his own.

    Young kids love the sound of your voice and can sense the enthusiasm probably. They will respond to that more than the content. My daughter was the same with stories about the ice age…

      Are you trying to say my daughter is obsessed with super heroes and Greek mythology because she got it from me and not just because she’s awesome?
