Dimensions in math

Not a long time ago, I was talking with a mathematician who had created some 3+ dimensions objects using a program then he had 3d printed some of them. How is it possible? He explained to me something like these objects could be (not entirely) in 3D but their area explained that they couldn't entirely be in a three dimensional space.

What do you think?

Questions for my Cyberdeck

Hi I'm back with some questions on my Cyberdeck project.

First of all, where to begin after finding the idea of my project ? Finding parts (practically done) ? And then ?

As well I want to have speakers but I saw that I'll need to use HDMI or jack (?) ports so I wonder if there's another possibility.

I'm thinking of beginning to design the keyboard (because it's really compact) and I'd like to have one like the PiCalc of Clockwork.

Thank you.

First DIY project ever, first cyberdeck, first...

Hello Reddit, it's my first post ! Finally !

So I want to create a cyberdeck a bit like the well-known Nintendo Switch but... I know practically nothing. Well, just some tutorials, docs, things like that.

Well, things are said, so I'll present the project: it'll be a small and portable cyberdeck with a main part which has a 5" or 7" touch display, a Raspberry Pi (probably the 4B but I'm still hesitating because of the thickness it'll add to the case), a main battery, *and perhaps an NVMe SSD.*

Then we have the Bluetooth keyboard part, a part that I'd like to be as much as possible DIY, with Adafruit tactile switch buttons (the 3101), my own PCB, a nice!nano v2 as the microcontroller(if you have a better idea for a beginner, let me know), and finally another battery.

So with that I want to slide the keyboard part into the main part using a sliding rail mechanism similar to the Nintendo Switch's one, then if it's possible, charge the keyboard part as well but it appears to me like it'll be rather impossible without a factory doing this for you...

Thank you for your attention, and if you can help me make this project realisable it'll be great.

Open questions I'm still figuring out:

* Display: HDMI, DSI, other ?

* Battery format for the main board etc. and overall case thickness given the Pi 4B + extras

* If you have some tutorials to recommend to me...feel free

Thanks!
