I don't know if that fits the sub, but if you're into that kind of thing (straight edge geometry) you might enjoy the game euclidea
Euclidea: A puzzle game where your tools are points, lines, and circles, and the goal is to complete the specified geometric constructions in as few moves as possible.
The first handful of levels are teaching you how to use the tools, then it pretty much immediately ramps up.
I have this game installed on my tablet, https://play.google.com/store/apps/details?id=com.hil_hk.euclidea
It's kind of super challenging really fast but also really engaging. I tried it on my phone, and I think the app could be written to handle it better, but it just doesn't work as well. Def needs a good size tablet. although the constructions on pen and paper are so fun to do.
Ehhh, I totally get your point, and in some contexts it's fine. Like, we don't KNOW there is a supreme being, we believe so. Until we meet one (or until we don't), there's no way to 100% know.
But the earth thing is straight mathematics. Understanding the concepts behind the calculations (and the fact that they should work on any scale, and therefore are testable on a smaller scale if you really want) leads to a good certainty that they're correct. If you want to see the certainty if mathematics, look to Euclid's 47th, or Euclidea.
Now. Having said that, you are still 100% correct that we do not literally know without sight. I agree with you. The math is rock solid and provable, but there's nothing like first hand viewing. I can't tell you the number of things I have understood intellectually (mostly really good advice about life and things in it), but didn't really get until I experienced them (usually through ignoring really good advice about life and things in it).
Not Masonic, as such, but this game "Euclidea" (https://play.google.com/store/apps/details?id=com.hil_hk.euclidea) involves compasses and straight edge geometric constructions.
It's a great way to learn about geometry.
Este jueguito de celular cambió mi visión de la geometría. Antes la miraba a huevo; ahora considero que es una herramienta hermosa para entender la lógica de las formas que aparecen en el mundo.

I will not try to promote any app, the link is just for the reference (https://play.google.com/store/apps/details?id=com.hil_hk.euclidea&hl=en&gl=US) to the possible controls in the game, which are used to solve different geometric problems. The controls are easy to understand and based on point to point approach (without a need of really drawing the line). Example: to draw a circle you just put 2 dots apart(center + the radius) Having the ability to specify the radius would be the cherry on the top.
There is an app called euclidia where you have to work out loads of the constructions. It's the only game that dosnt feel like a waste of time to me, definitely check it out. here's a link
In Danish it's a "passer" in daily speech, and more more specifically "passerben". Strange word. The origin is however German and French compass(legs).
Anyway if you have never encountered Euclidean geometry, you might find it interesting how many mathematical concepts have their origin in this specific tool. It was definitely not part of my curriculum, but in hindsight think it should have been, because it gives a completely practical approach to complex math.
There's a couple of apps for anyone interested in this. I'd recommend Euclidea
Euclidea is a geomerty puzzle "game" where you use basic forms (lines & circles at first, then expanding to perpendicular, bisectors and more) to reproduce geometric figures. Kept me interested quite some time for a mobile game.
euclidea. many times. and i keep going back after long whiles.
i love geometry above all forms of math, probably. and i love math, logic, binary, all things boring in that way.
but there's just something so annoying about this game...
this is my 5 star review:
annoyingly difficult game, part of a rare category today. there's close to no gamification or rewards. no holding hands. you have to read. and challenge yourself. and yet... wonderfully done! without ads!! for learning math!!! hope they can fix the payment issues soon, to open up the possibility of easing up the games with hints, for those who want to cover up ignorance with money or simply support such a great game.
You need to make various geometric constructions using just a compass and straight edge (you do unlock convenience tools, like bisecting a line or an angle, after you manage to complete those tasks using just the two basic tools).
There's IAP to unlock all the levels. You can also unlock the levels without paying, but you need to get perfect stars on every level (each level has challenges for doing it efficiently).
Check out the game Euclidea. This is basically the whole game
Here are some of my favorites
Geometry : Euclidea, Pythagorea, Pythagorea60;
Mental Math: Mental Math Master, Calculator the Game;
Not exactly math related but great for practicing problem solving skills: Circuit Scramble, Cell Lab;
Math for Fun: Golly, Visions of Chaos.
Reminds me of an app I have on my phone Euclidea. Fun but I'm awful at it.
If you enjoyed this you might like Euclidea.
Or this, loads more levels and it gets rather fiendish...

Not algebra or calculus, but for Geometry you can try Euclidea. There are two similar apps called Pythagorea and Pythagorea60.

Looks like a real-life version of the game Euclidea.
Euclidea can get pretty tough... Not logic. But great geometry puzzles..

If you'd like to gamify creating this kind of geometric shapes, I'd suggest you try Euclidea. It's great.
Now it is. Euclidea for Android: https://play.google.com/store/apps/details?id=com.hil_hk.euclidea
