> Hiragana being far more useful to know starting out, if you had to pick one.

Before visiting Japan, I learned to read in both Hiragana and Katakana, but I didn't really know more than a dozen or so words in Japanese. While visiting Japan, I found Katakana to be a lot more useful, because it's commonly used and often is just English words converted to Japanese letters. I think all my Hiragana reading abilities were completely useless as I couldn't tell what I was reading.

Is it reasonable to view the Cosmic Microwave Background Radiation as being the limit of this? The remains of the big bang, maximally scaled up and red shifted as far as things can be today?

So essentially one giant blob of cosmic background radiation was at the time its light was emitted, the size of an atom or so?

How do people pay the bills when they start a company? I'd go start a company right now if I could figure out how to pay my car payment while doing it.

Maintain low expenses, be OK with going down in life quality, be willing to burn through your life savings and be OK if you lose it all.

I did it once, now doing it for the second time. I think most people will not bear it, but for me it feels like the only natural thing to do.

I can never imagine enjoying either running a hyper-growth VC funded company or being an employee, and I realize most people are not like that.

So on that end, maybe ask yourself if you were OK with cutting costs like losing the car, moving to a smaller apartment (even back with your parents) etc. and be happy about it even if your company flops.

Thank you! Not only I 100% agree with you, you've also managed to provide a few terms and phrases I've been missing, which could've cut my previous comment down to 1/4 of its size, without loss of meaning. Specifically:

- "chocolate covered broccoli"

- "catalyst for learning"

- "inspiration to learn"

> I learned and practiced most of my English from playing video games, and they were the catalyst to make me WANT to learn English, but they didn't exactly teach* me English.*

English is my second language, and I've also learned most of it from video games. Mostly from exposure, but initially through focused effort - I still vividly remember that time when I was maybe 10 or 12 years old, when I made screenshots from loading screens in Star Trek: Generations, and printed them out on paper, one by one, directly from MS Paint, to take back into my room and meticulously translate the story text on those screens, looking up every single word in an English->Polish dictionary. I also remember keeping that dictionary around when playing Fallout 1. The need to understand the stories and dialogues in games is what bootstrapped my English.

> I bet if you sample today's scientists and engineers at places like NASA, you'd probably find that a lot of them loved watching Star Trek/Star Wars as kids. So while sci-fi hasn't taught them how to work with Schrodinger's equation, it probably had a major part of what sparked their motivation to get started.

I agree. And Star Trek is, in fact, what got me interested in STEM. I owe my entire career and most of who I am as a person, to early exposure to captain Picard and the adventures of Enterprise-D.

(A lot of my early STEM self-education was driven by trying to understand the so-called "technobabble", which - at least in TNG - actually made sense. Probably because, in those days, they had proper scientific advisors.)

> Games probably do that too, and then some, thanks to interactivity.

Yup. I mentioned KSP for a reason - not only have I read the accounts of parents impressed by how much advanced math and physics their 8-12 years old kids can pick up, just for the sake of getting better at the game, but myself I also learned these things for the same reason. While Star Trek is what got me interested in space in the first place, KSP is what got me to finally grok how orbital mechanics and rocketry work in reality. It also made me no longer able to fully enjoy any space travel fiction, except for diamond-hard sci-fi.

:D

I should probably give KSP a try again. I guess there's an initial threshold I got to power through first, as I got a bit exhausted after the first mission hehe.

I'm actually working now on a game of my own, with themes of science, and it's indeed a game-first approach rather than an educational game, but I do hope to maybe inspire some ideas and motivation with at least a few players.

I totally believe there's a lot of untapped potential in this area, and advancing towards cracking learning motivation + capabilities could have a huge impact.

I'm sure someone actually working in ed-tech will correct me, or perhaps even laugh me out of the room, but I still believe in what I figured out around highschool: that edtech, particularly "educational games", have it all backwards.

Kids aren't stupid. If you take the usual boring curriculum with choreful exercises, and try to "make it more fun" by half-heartedly sprinkling in some colors, characters and cheesy stories, it will backfire spectacularly - kids will see you're just trying to trick them, and not even putting much effort into it.

The right way is the reverse: you need to make something honestly, inherently fun, but design it so that it educates users/players as a side effect. Take Kerbal Space Program: it's not designed to be an educational game, but it's fun, and models real-world physics well enough that you get 12 years old researching and understanding the math of orbital mechanics, all because they'd like to do better than "point roughly half-turn ahead of the Moon and go full throttle", and they'd like to not run out of fuel on the way. Or, look how Minecraft is tricking kids into learning electronics, boolean logic, low-level programming, etc.

(I'd mention Factorio, but I think it's a wash - any gains society gets from the game educating kids are cancelled out by the amount of productivity loss the mere exposure to this game inflicts on software devs.)

(EDIT: or, remember Colobot? A very simple third-person perspective game that had you find and refine resources to build robots, which then you used to kill some big bugs. The twist being, instead of controlling the robots like in a shooter, you had an option to program them in a Java-like DSL, inside the game. It was a great way to organically learn programming. The IP owners later made a "fork" of the game, Ceebot, that was pretty much the same, except it focused on teaching you to program robots instead of having fun exploring and shooting stuff. Predictably, that simple change of focus made the game flop.)

It doesn't even have to be a game: leave a kid in front of Google Earth, and they'll learn geography much faster and much more thoroughly than they would from a globe or a book. Not because the software is better at teaching, but because the kid is just messing around with a virutal model of Earth, and learning stuff along the way.

Etc. Etd.

I think it's a tough sell to adults, particularly parents and educators - that if you want to motivate kids to learn, you need to... stop trying to motivate them to learn. Give them something that's honestly fun, involving or benefiting from real-life knowledge and skills, but actually trying to teach them - and then trust that they'll pick that knowledge up on their own.

They call these kind of games "chocolate covered broccoli" and I totally agree.

I think games, have lots to teach, but that most of the time they are a catalyst for learning or inspiration to learn, but on their own, they will rarely actually teach you. It's hard to put the finger on it, as for example, I'm not a native English speaker, but I learned and practiced most of my English from playing video games, and they were the catalyst to make me WANT to learn English, but they didn't exactly *teach* me English.

Another part of it, is I bet if you sample today's scientists and engineers at places like NASA, you'd probably find that a lot of them loved watching Star Trek/Star Wars as kids. So while sci-fi hasn't taught them how to work with Schrodinger's equation, it probably had a major part of what sparked their motivation to get started. Games probably do that too, and then some, thanks to interactivity.

> I really struggle to learn anything which I can't see a practical use for.

That's a close-minded, ignorant world view. Much of the world's most important advancements were made before any practical use could be seen. Why do you think that way?

drorco · 3 years ago
It's just the way my mind works and motivated. Motivation is a very elusive feeling that I did not find easy ways to manipulate. It's not as if I'm totally blocked from learning stuff with no clear purpose, but it will require much more mental capacity that is often difficult to muster in the day-to-day routine. Another example, is I did try to learn what I perceive as totally theoretical math such as "prove that there are infinite primary numbers" which was a nice idea to entertain, but it didn't really make me want to dig in further. On the other hand, learning about linear algebra in the context of machine learning, suddenly got Linear Algebra a lot more interesting and easy to learn.

It's mindboggling to me that every teacher doesn't just debut the subject with videogames as a reference.

"Alright everyone, let's make a video game character out of triangles".

"Let's make a little cannon that you can change the angle of. How do you calculate the angle? Funny you should ask.."

"Now let's learn how you'd make the fireball move up and down as it travels. That's a sine wave!"

Every single student understands the basic concept of a game visually, even if they don't play them regularly. It's just a perfect frame of reference and context for applying the concepts in 2D, and then in 3D. And it's so easy to help the students understand how easily those concepts get extrapolated to other things (engineering, sports, whatever).

Totally! One of the first thing I did after learning Newton's law of gravity, was to write down a small simulation of planets in orbit and how they "dance" around each other. This little exercise totally blew my mind and the code was really simple to code.

There's probably an untapped opportunity here, but ed-tech is such a difficult industry.

I was the other way around. Only when I found utility in something could I finally grasp the subject properly. I remember how I was taught derivatives and integrals in HS, I knew how to do them but I was confused as hell. I asked the professor and once explained some uses it all clicked into place.
drorco · 3 years ago
Same. I really struggle to learn anything which I can't see a practical use for.

Just as an example, in high school learning trigonometry was really difficult for me, like why would I even care about finding an angle in a triangle, etc.?

Only once I studied physics or game dev, this has started to become relevant, and then studying it got SO MUCH easier.

amazing advances this year. Remember the guy who created the 2d platformer thats based on time, what was it called again? He spent around $100k+ just for the art, which I am pretty sure was a huge expenditure for him, with this software he could have done it virtually for free without much artistic talent at all.
drorco · 3 years ago
At the quality of the current output, I think players still easily differentiate between AI generated art and hand-created art. Maybe in future versions this will be less noticeable.

As a game dev, I think at this stage AI can be a helpful utility, but it does not replace a designer's touch for professionally looking games.

I'm no expert with LEDs' technical bits, but I purchased LIFX bulbs which were pretty expensive and they've lasted for almost a decade now.
