simply imagine another dimension whose axis is perpendicular with respect to the axes of the previous dimensions

For 4D I think most people just imagine something 3D and then have a mental slider that they push forth and back for the last dimension, alternatively you can use time.

do not bother to imagine anything higher than 3d. just treat it as 3 values, 4 values, 5 values, etc

what you will be doing is imaging 4 dimensions projected in 3d space

but fret not, because you can be perfectly content in this realm of 3 dimensions

Colours, friend. Whenever I have to visualize somethig in 4D, I give them colours and pretend different colours can't interact with each other. You can extend this to n dimensions by giving them other properties.

Our eye cells forms a '2D' array. '3D' is one more, that is, the least more than two dim. So we THINK that there is dimensions (and 3 of them). They are just a mirage.

My brains exploded when i realised that.

Its actually not but because you're too afraid of thinking for yourself you haven't discovered ways to think about 4d.

Reality isn't like that, rather this is uncharted territory in human knowledge. And by the way all humans do think in 4d given the fact that time exists and we all have memories...

Higher dimensions are obviously correlated with lower enjoyment
This is demonstrated by the well known law of 2D > 3DPD
In fact, we should be heading into the opposite direction and trying to imagine 3D structures (such as cute girls) in one dimension, which will surely be the pinnacle of beauty

Is it the same as valve actuator? And if so how to get that block, it's not in my library. Do I have to download a package or something?

Its actually easy. You do it by extending with rgb color as additional dimensions.

The only problem is that you cant observe even 3d in one go. You always get merely a 2d slice and then have to observe sliices to get a understanding of 3d form.

OP you should read pic related. It's not easy to visualise four dimensions but there are lots of tools for studying it.
A good warmup is starting with three manifolds. Can you visualise $S^3$ ? How about $S^2 \times S^1$ .

>>13480915
This is a very surface level approach. There's a lot of stuff that works very differently in dimensions three and four compared to higher dimensions so it's not always helpful to imagine n dimensions and set n to four. There's a reason low dimensional topology is its own entire field.

I can imagine extruding a 3d object into another dimension but rotating it is very difficult for me. I cannot let go of the notion that the 4th dimension is something separate from the first three, and so my rotations are only in the first three dimensions.

Well, no; just because your eyes view things 2-dimensionally doesn't mean you can't create a neural embedding of an object by walking around it. And people have, with ML models.
There's also no reason you couldn't do this with even higher dimensions, though it becomes impractical and returns diminish at some point.

False. Time is not a spatial dimension, rather a description of 3-D space’s movement. (Sun goes up and goes down that’s 1day) the only reason we had to invent the concept of time is because of movement.
Time is not the 4rth dimension

What's color? I keep reading and hearing this word but nobody has ever really been able to explain this object property to be adequately before. I just internally convert their RGB colour map name values to a triangle tree based on descriptive context vectors that apply to the object color presented to me.

I also have a few words clouds regarding colours but I'm still unable to fully comprehend that color is somehow an inherent trait to experience. Purely because I know that I've never been able to subjectively populate the word color or its variants in my own life thus far.
