I've been VERY public about the fact that 10 years on, I still wasn't over the loss of what FEZ II could have been. And I'm being VERY serious. I think this documentary was my way of letting go of my grief.

For most of my life I've had little to no trouble describing the 4th dimension. Now picturing it, that's a different story. When I was younger, about 11 years old, I was in my great grandmother's living room watching TV. Some science program was on and I was enthralled. The episode was about flatland. While it discussed the concept of a 2d world, something clicked in my head. I realized that beings in the 2nd dimension, or "flatland", would see things in the 1st dimension and could only differentiate distance with light or the 2d equivalent. I then realized that we are the same, just bumped up a dimension. Everything we see is a 2 dimensional image and distance is only determined by light and shadows, as far as our brains are concerned. So, for the 4th dimension, you just bump everything up a dimension. So a fourth dimensional being would see everything in the 3rd dimension. If a 2d resident was sitting in his room, looking out a window, a 3d resident could look at them and see their internal organs, their entire house, and even the space around their house. Of course, the distance visible depends on the size of this flatland in comparison to the 3d resident. Now imagine a 4d resident looking at us, the 3d resident. They would be able to see our organs, the entire building, every room, as well as the insulation in the walls, and the space around the building. Just like us looking at flatland, they would see every angle, of every being and object. All while staying completely invisible to us. I believe that humans are capable of picturing and understanding a 4d plane, if we had a reference for one. It's impossible to picture it if we don't have any idea as to what it looks like. There is absolutely no shape or image to give us an idea of it's true form. The situation reminds me of the king who had a pet tiger. He loved the tiger so much that when it passed away, he wanted it stuffed so it would remain with him. The taxidermist he gave the job to lied about knowing what a tiger looked like. So with only the skin and bones of the animal and no idea what it looked like, he attempted to recreate it. It looked very goofy and not really like a tiger at all. That's a true story and you can look up a picture of the stuffed tiger. My point is, even though the taxidermist had the skin and bones of the thing he needed to recreate, he failed miserably. So imagine if he didn't have the skin or bones of the tiger. He only had a confusing, vague, and sometimes contradicting description of what a tiger looked like. Now imagine the description of said tiger completely destroyed the laws of physics and simply couldn't exist in a physical form in our universe. It's nearly impossible to fully picture something if you've never seen it. It becomes definitively impossible when you have absolutely 0 references to go by. When literally everything you've ever experienced is from a 3 dimensional perspective, you can not imagine existing in a true 4th dimension.

I just realised something. The 3d games and software we play aren't actually 3d. The content exists in a 3d plane but its projected through a 2d camera. Our eyes work like that too. Depth perception isn't actually 3d. Even rotating the 3d object allows me on to perceive the surface a 2d. I cannot see behind it and in front simultaneously. I'd have to occupy all the space around it at once. To perceive 3d to me would mean you'd have to occupy the entire 3d space at once at the same time. I'm truly ignorant here but could that be something like the medium the 3d space exists in? Kinda like how a line imexists inside a paper, leaf, tree or anything that has a 2d surface? What comes into my mind and like i said i dont know anythibg and could never prove this, is that it is the medium which this 3d space itself occupies. So the issue to me isn't about perceiving the world in 4d, but what blows our mind is perceiving it in 3d. Perceiving it in 4d is just beyond our imagination. My mind tellse there's no way. That would be like bending space onto itself. Like i said i don't know what i'm saying. It just purely informed speculation

I am amazed that you captured so many of my favorite uses of 4D and 4D-like moments in games and media, seeing them all together and one video actually sent chills down my spine! Incredible work, thank you for all the time you put into this!

Hey Renaud! 🤩 Great to see the video somehow found its way to you! Contacting Polytron is ...surprisingly difficult! 🤣 I actually had a small section about Flatland, but it didn't make it into the final cut! I thought FEZ was already, in its own way, a sort of 3D flatland! And yes, this is indeed a love letter to FEZ. 💌 It's a game that didn't just inspire people, but one that actually changed lives. Mine included. So thank you for helping making that possible. 🙏 If you look at the comments, many are actually expressing their grief at the cancellation of FEZ II. And I think "grief" is the proper word to use here, because its loss is something many are not over yet. I think that in a kinder world, this documentary would have been about FEZ II instead. So in a way, this was my way of letting go of that grief, and making peace with the fact that no, we don't actually live in that kind world I long for.

Wow! Such a beautiful video, Alan. This really re-sparked my old interest in the topic of 4D. Thank you.

You’re welcome! I love the effort you put in your videos

You might call me crazy but I think I understand why we can't understand a rotation on a wx, wy, wx, wz axis, no and why we can't see 4d, but the factor of how our brain perceives shapes Geometrics always seeing in perspective even changing the shape of the object and therefore when we see a 4d object as a thesis we see the cube phase because we cannot understand that it is flat and to prove this, draw two squares without connecting them with canvases, you can see the square but connect one and you will see a cube our brain gets used to seeing everything as square rectangle cubes It is not a mental limitation but a practical one However, there may be a shortcut to this practice the touch without picking up any object, if a 1 year old child sees the 3d shadow of something and sees that something moving, he will think that it has changed the shape but if you give the cube to the child without touch, he can understand how the rotation works the d axis is just a blind angle in our vision that everything from all directions looks the same but if we hold it in our hand the progression of rotation w can be recorded We possibly do not understand the 4d of objects because we are not taught as children to visualize them now everything I said sounds like crazy nahh and it's just a reflection that I did with some experiments to visualize and project 3d leftovers from something 4d like tesranc lol

I guess this would explain how a 4D observer would also be able to see inside of you. If it was only 1 cube I think it would be turned inside out when its wrapping back around without the other cubes protecting those angles.

It's one of the many risks of being exposed to the fourth dimension.

It is not accurate to say that points on the Koch curve can't be described with a single coordinate. They can. The "topological dimension" (as it's known) of the Koch curve is 1. There is another notion of dimension, the "Hausdorff (or fractal) dimension," which puts it between 1 and 2.

Sure! What you're referring is known as SPACETIME. Basically, to identify an event in our universe you need FOUR coordinates: WHERE it happened (x, y, z) and WHEN it happened (t). So we live in 4 dimensions: three spatial ones, and one temporal. But Einstein's spacetime is still 3D when it come to space. What I'm talking in the video is imagining a universe where there are FOUR spatial coordinates: x, y, z and w.

Not necessarily. You can use time to show a 4D dimensional object: i.e. showing a 3D object changing over time. But it's like saying that the 3rd dimension of a 3D object is time, and you're showing 2D slices of our world. "True" 4D objects are different from 3D objects which are changing over time.

You were doing fine right up until the point where you decided to assume the two dimensional beings would only be able to see a slice of a three-dimensional object that intersects with their two dimensions. That's not how Imaging works. Already humanize essentially have a two-dimensional surface and the lens that casts a projection of the world around us onto that two-dimensional surface. If we used the same lens but only a one-dimensional slice of our retina, we would get pretty much the effect that you're talking about seeing only a one-dimensional projection of a two-dimensional slice of a 3D World from our point of view, but a different sort of lensing system could be used to project the 3D scene onto the linear strip of retina, and likewise a two-dimensional being able to see three-dimensional objects could do so properly if the three-dimensional scene were projected onto it's effectively one-dimensional retina. That's not a slice. It's a projection, but it's not a projection of a projection. It's a direct projection.

@AlanZucconi

Hi! That's an interesting point! I wasn't talking _directly_ about how eyes and retinas would work in 2D. Mostly because that would entail a lot of assumptions! My main argument is that only the 3D points that intersect the 2D plane would physically manifest in that 2D world. So those are the only points that can actually appear and be perceived by beings locked in a 2D slice. How they would physically "see" it, is not something I've really discussed!

We use four-dimensional objects every day (such as quaternions and homogeneous coordinates!). They're REAL, but they're not PHYSICAL! In a similar way numbers are real, but they're not physical.
