It's actually a "physics" course which is actually about 50% math and 50% java programming.

We're using "Mathematical Methods for Physics and Engineering" (ISBN: 9780521679718) för the math part, IMO it's a pretty good book.

I'm taking calc III too, but we haven't looked at a gradient field once yet.

I just looked and it is literally the next section in my book though. I guess that explains it.

Also just noticed it was using a function of (x,y), so that makes sense.

Why java though? My "engineering programming" type class is in C.

That mashup does seem pretty interesting though.

I dunno, technically it's theoretical physics, perhaps java is more common in that field.

Can somebody explain me what a tesseract is exactly?

I understand how it's the visible "shadow" of a 4 dimensional cube in the 3D world, but how exactly did we come up to that specific form?

Would really appreciate if anybody could enlighten me on this matter

>>

>>852180

http://jazzeria.deviantart.com/art/How-to-Draw-a-Tesseract-28094461

>>

>>852180

we assume there is a geometrical pattern and try to continue it.

a 1d "cube" has 2 Points and 1 Line.

duplicate a 1d "cube" and move the second line into a second dimension (perpendicular to the first), tracing the points (so that what previously were the same point before duplication and moving are now connected with a line). we end up with a 2d "cube" with 4 Points, 4 Lines and 1 Face (aka a Square).

duplicate the 2d "cube" and move it perpendicularly into a third dimension, again leaving traces. now we have a 3d cube with 8 Points, 12 Lines, 6 Faces and 1 Volume.

now the thinking goes - what if we just repeat that pattern? we duplicated the 3d cube, move it perpendicularly into a fourth dimension and trace the path, so we end up with a 4d "cube" with 16 Points, 32 Lines, 24 Faces and 8 Volumes.

since we lack any sort of understanding what a fourth spatial dimension might look like and how to properly represent it, we just draw connections diagonally away from the previous vertices so the thing ends up looking like a small cube inside a large cube. but all squares are actually outside faces, we just can't draw it that way.

don't worry, the whole effort is stupid. it's quite natural to not follow this "logic". our brain is hardwired to deal with 3d stuff and 3d stuff only. that's why we can look at a 2d drawing of a cube and immediately make sense of it. we have absolutely no intiuitive concept and a severe lack of brainpower concerning anything 4d. and now trying to represent a 4d object in a 2d drawing (on paper or on screen) is just bound to fail. we would at least have to use 3d, the same way we can't represent a 3d cube properly in 1d.

Okay short summary:

To go from 1D to 2D, you take a line segment (red) you add two adjacent line segments on the two points (green) and add one final segment opposite the original (blue). You fold it through the second dimension so all the remaining points touch, and you get a square.

2D to 3D is the same; square (red) four adjacent squared on each side (green), one opposite square (blue). Fold so the remaining edges touch and, boom, cube.

A hypercube(tesseract) is exactly the same thing. Take a cube (R), add six more cubes on each face (G), and an opposite cube (B). Fold it so that the faces touch and you get a hypercube. To get the 3D imitation-hypercube like in the gif you deform it in 3D instead. You will notice on the fake hypercube that there are only two cubes; the small inner one and the (inside-out) outer one. The remaining six cubes have to be mushed into truncated-pyramids to get all the faces to touch.

This process continues on indefinitely. For example you can make a pentaract by adding eight more tesseracts onto each of the cubes of a base tesseract, plus the opposite tesseract and folding so the remaining cubes touch.

As for the 3D tesseract being the "shadow" of the real 4D thing, that's wrong; its just a... "metaphor" to help you visualize the real thing. No idea what a hypercube's shadow would look like, but by "shadow" I assume you mean what it would look like to us if we saw one IRL. We'd probably see a cubic or rectangular-prism cross section of it depending on at what angle it intercepts 3D space, similar to how a cube produces a square or rectangle cross section in 2D.

Do you not understand how gravity works? If they spawn outside the area the fall into the gravity well gives them enough speed to climb back out unless they get trapped. This is why orbits are ellipses and not spirals ending in collisions.

You do know that an attractor has a precise mathematical definition right? This has nothing to do with gravity.

Is this what old fags can do

>>859499

if i had to guess, it has to do with where the origin is. normally you "start" at x = 0 and let x increase when you're plotting a cartesian function, and normally you start at theta = 0 and let it increase when you're plotting a polar function.

i imagine that the first rotation has to do with the established conventions on how to translate between the two coordinate systems, and if it were not done the resulting polar graph would be shifted by half a period or something from the graph that has been established as the polar analog of that particular cartesian function.

>>859569

that being said, it's possible that with this particular function, it happens to look the same with or without the first translation and it was only included for correctness and not because it was visually necessary. that might not hold true with other functions.

Now here is my question.

We can illustrate 3d cubes in 2d easily, you do it in your image.

Also in your image you illustrate a 4d cube in 2d.

Can we not make a 3d representation of a tesseract?

>>

>>874446

>Also in your image you illustrate a 4d cube in 2d.

he really doesn't though. all areas defined by 4 points in a plane are squares and outside faces. all volumes defined by 8 points are non-intersecting cubes. all angles are 90°.

nothing of this is properly represented in the drawing, so it's really more of a cleaned-up artist's representation governed by how to neatly tuck everything away, rather than how it would actually look. doing a model in 3d based on that representation would just end up as a cube with the rest invisibly taking place inside. or visibly if you use translucent material.

so the trouble is twofold: 1) for an actual representation we need a fourth 90° perpendicular, but after three we've run out. 2) the 2d wireframe drawing cheats by showing us things that lie behind faces or inside volumes.

if you colour the faces of the 2d drawing, it'll look just like a cube, the same way an opaque 3d model would. which is not even a bad representation, since a 4d cube intersecting 3d space would indeed look like a 3d cube, just like a 3d cube intersecting 2d space looks like a square.

this concept is easiest shown with a sphere, so we don't have to care about orientation. if you take a 3d sphere and pass it through a 2d plane to an observer on that plane it would look like a dot growing to a circle and shrinking back to a dot. so a 4d sphere passing through our 3d space would start as a dot, expand to a sphere and shrink back do a dot before disappearing. spooky :-) i like the idea there is an infinitely larger 4d space outside of 3d space, the same way there is an infinite 3d space outside of a 2d plane and that space goes into a direction an inhabitant of the 2d plane could not hope to comprehend, because "up" or "down" is meaningless in 2d.

>>

>>874446

You will note that to a being in 2d space the cube drawing would look like an irregular hexagon (from the outside) and the tesseract drawing an irregular octagon.

Theoretically a 4d being could make a 3d drawing that to them looked like a tesseract, but to us it would just look like some weird 3d shape.

As I stated above and >>874504 also mentioned, the best we are getting (bar some advances in cyberbrains and 4d modeling software) is 3d cross segments of higher dimensional objects

The thing is that if you divide a number line into a lot of pieces you can get arbitrarily close to pi but you can never get exactly pi, you always will be off by just a little bit. Like, we define one u as 1/12th the weight of an atom of carbon, but if we try to get that with hydrogen atoms, you will find that putting 12 atoms of hydrogen together, they weigh just a little more than an atom of hydrogen.

The concept of infinity is a simplification of reality that is only used in math because it makes stuff easy. In reality, pi doesn't even exist because everything is quantized.

In that image, too, the dots/pixels/photons are limited.

So no, pi has no end digit, but it also doesn't really exist.

I don't believe that that counts as a steradian. I might be mistaken though. Last I learned, a steradian involved the 'chunk-angle' of the sphere itself, not just the surface.

>>884544

Taking a 3d sphere to 4d would be just like taking a circle to 3d. Inflate it through the 4th dimension till its spherical no mater which direction you look at it from (like how a sphere is appears circular no matter which direction you look at it from.)

For any of the platonic solids just follow the cube method: original, one on each face, opposite, fold closed. The 3d "metaphors" would (I assume) follow the 'small inner shape, truncated pyramids, large outer shape' pattern.

More complex shapes (what I assume you mean by 3d model) would follow a similar pattern (if somewhat harder to visualize).

Imagine, above your head, in a completely, perfectly flat square, is a 2d realm. Everything is just flat lines.

Imagine, if you will, that you poke your finger through this realm. Because there is no depth in this realm, your finger appears as a rough circle, changing in shape as your knuckles pass through, and finally changing shape completely as your hand passes through.

Does this make sense?

Oddly enough, anime helped me here. This is a scene from the remake of Evangelion. The story requires a shit ton of explanation and it will always be 2deep4everyone, so here's the important stuff:

This thing is a 4 dimensional creature. In our world, it appears as a big blue octahedron, but you see, only a slice of it appears in our world. when it moves in the 4th dimension, it moves in seemingly impossible ways in our dimension, but that is because it is not bound by our laws. In that way, it is similar to moving your finger and arm through that 2-Dimensional realm; if any creatures were alive in that 2D realm, your arm changing 2D shape and position would seem impossible to them, but looking at it from your perspective it makes perfect sense.

Does that make sense?

Doesn't work, that gif only works because the new shapes on the border created by the overlap are still triangles.

Or at least, it doesn't work the same way. You could makes something if you changed the method, but it wouldn't seems like a square equivalent of the pattern.

Honestly, that seems kind of dumb. Math isn't beautiful on its own, at least without reference to any real world applicability or foundation in phenomena that can be witnessed in some way. Like you can say some formula is right but if there is no way to relate that to anything can even be theoretically witnessed, then who the hell is going to think its a beautiful outside of gimmick pop-sci formulas like Tupper's self-referential formula.

I've always thought that this sort of animation is basically going from one number to the next number on the number line. I think this because it seems to show these brief moments of dots going (not really in this animation because it's slanted) parallel to each other. Moments where it's the two lines of dots giong paralel, other times more. I'm hypothesising that it's going through the number line and hitting the different fractions (1/3,1/2,1/4 etc.) on the way. Can anyone confirm/tell more about this?

You know what's really beautiful, though? Proving trigonometric identities like Pythagoras's using Euler's theorem.

Taylor's proof of Euler's theorem is the most beautiful thing I have ever seen in my life. When my differential equations professor first showed it to me, I was literally on the verge of tears.

>>

>>883936

>However, people so often forget that the math describes the reality. The reality has to come before the math, but people do enjoy creating reality out of math.

That's a debateable statement. It is a big unanswered philosophical question whether math preexists the universe or vice versa.

I personally disagree. I think math exists independently of the universe.

How we get this representation is from a 2d representation of a 3d cube. A 2d representation of a 3d cube is a large square with a smaller square inside of it, and all the corners are connected. A 3d representation of a 4d object is the same, a large cube with a smaller cube inside of it, all it's corners connected respectively. When you rotate it something interesting happens. Watch this gif and imagine that you can't see the 3rd dimension. One side of a square just seems to stretch, while the other side seems to shrink. In reality the lengths of the sides never change.

Except that they can, you fucktard. Literally any real number can be represented uniquely by base-10 Cauchy sequences, which are decimal expansions of the number.

I'd prove this fact to you but it seems like you haven't even gone through grade 6 arithmetic.

As you get farther from the center a longer section of perimeter is covered by each degree of rotation, so it moves faster near the corners.

Okay shorter summary:

Fold 4 lines in 2D, get a square.

Fold 6 squares in 3D, get a cube.

Fold 8 cubes in 4D, get a tesseract.

See image >>856022

The hypercube isn't a tesseract. (It only has 2 cubes, the other 6 volumes are truncated pyramids [or other configurations while moving].) However, if it might look like a tesseract to a 4D being depending on viewing angle. (Similar to how we can look at a 2D drawing and see a cube.)

This may not have worked, because I'm trying to explain a 4d object to someone who thinks in 3d through a 2d medium.

But essentially, each new spatial dimension is perpendicular to all existing spatial dimensions, so a hypercube is just cubes stacked in a direction perpendicular to X, Y, and Z.

>>926184

Don't really have a background in higher mathematics or geometry, kinda picked up shit here and there and reasoned out the rest. I'm also possibly autistic so it's possible my thinking about basically anything is fucked. I know there are other ways to demonstrate it, this one just makes the most sense personally.

Am I at least correct?

>>

>>926194

Yes, you are correct, its just that text doesn't demonstrate it particularly well, especially when you try to add the third and forth dimensions. I know what you are trying to say, so it makes sense to me, but I doubt the arrows make a lot of sense to someone who doesn't quite get it yet.

>>

>>926215

Yeah, I kinda had to improvise, drew up a picture but 4chan wouldn't let me upload it. This was the best I could do regarding visually demonstrating it. I find that just trying to explain it with words doesn't work, particularly for someone with adhd.

>>

>>926228

/wsg/ only lets you upload .gif or .webm images. You can post it if you convert it to a gif, though a mod might remove it for violating the "no static gifs" rule, but since the thread is autosageing I doubt they will bother.

>>

>>926230

I know, originally had it as a .gif, still wouldn't let me.

>>

>>926240

Huh. All I can think of is see if you managed to exceed the max file size or something, otherwise I have no idea what's wrong.
