berkan Posted February 28, 2004 Posted February 28, 2004 There are 10 proven dimensions mathematically. Can anyone visualize a fourth dimension? Is the reason why we can't visualize a fourth dimension that we live in a three dimensional world? How different do animals see the world? (Axis-wise x,y,z). There's a saying "a triangle would have a god with three sides" we visualize a god in 3d, how can every dimension have a god?!
YT2095 Posted February 28, 2004 Posted February 28, 2004 you`ve pressented no less that 4 individual questions there, which do you want answering as 3 are totaly unrellated to each other.
fafalone Posted February 28, 2004 Posted February 28, 2004 I wouldn't really say proven, since it's a part of string theory... some models of which also predict 11 or 26 dimensions.
berkan Posted February 28, 2004 Author Posted February 28, 2004 Sorry for the bombardment of questions. My main question is (another question): Why can't we visualize four dimensions?
YT2095 Posted February 28, 2004 Posted February 28, 2004 because that implies sight, and the 3 dimensions we can SEE can we SEE the 4`th? that`s probably the reason
Pinch Paxton Posted February 28, 2004 Posted February 28, 2004 I can visualise time in a 3D environment. I think that Dimension is a confusing word though. I would personally only allow 3 Dimensions. Then time would be just called time. The other dimensions are just patches covering a leaking innertube. Pincho.
fafalone Posted February 28, 2004 Posted February 28, 2004 well the 4th dimension is time... so we can indeed sense 4 dimensions.
berkan Posted February 29, 2004 Author Posted February 29, 2004 What exactly do you mean by sense? Can you (touch, hear, taste, smell, or VISUALIZE (see)) a fourth dimension? You can't, no one can. Let me put it this way: If I asked you to draw a 3 dimensional shape you would draw a sphere, cube... etc. Now let's see you draw a four dimensional shape. We don't sense 4 dimensions. We experiance its effects (time). And the effects of all the other dimensions even though we can't explain them yet.

We can see 4 dimensional objects, by creating perspective in 3D, similar to viewing pseudo3d objects in 2d. For instance, the university of warwick has a 3d imaging system that you can view a hypercube (for instance) in. I've seen one. Of course, some peoples' brains can't visualise 4D objects, or at least that's the theory.

The hypercube image is displayed in 3D space in reality?

Hades Posted March 1, 2004 Posted March 1, 2004 ignorant question perhaps, what would these other two dimensions ... be, basically? edit: other 22 dimenions look like? or their concepts?
neo_maya Posted March 1, 2004 Posted March 1, 2004 Hmm........This dimension stuff is always kinda confusing. Here is one question - someone once told me that the fourth dimension is arbitrary (not necessarily time). I mean u can pick anything u want ( don't have a clue what that anything could be ) and assign it 4th dimension. Is it true?
alt_f13 Posted March 1, 2004 Posted March 1, 2004 The name is arbitrary. There is no set 4th dimension.. just like dimension 1 is not up or sideways or whatever.

I do not have the glasses and can not see it, but had seen someone else post this elsewhere: http://dogfeathers.com/java/hyprcube.html
JaKiri Posted March 1, 2004 Posted March 1, 2004 That doesn't really show what it's like. It's like trying to show 3D perspective by drawing a line.
berkan Posted March 1, 2004 Author Posted March 1, 2004 Does a four dimensional shape (hypercube) represented as a 3 dimensional one always have to be in motion.
MishMish Posted March 1, 2004 Posted March 1, 2004 MrL: "That doesn't really show what it's like. It's like trying to show 3D perspective by drawing a line." Oh. Then perhaps is just as well I could not see it Unsure then what you are referring to
JaKiri Posted March 1, 2004 Posted March 1, 2004 berkan said in post # :Does a four dimensional shape (hypercube) represented as a 3 dimensional one always have to be in motion. What?
YT2095 Posted March 1, 2004 Posted March 1, 2004 I think he means in order to make it a more accurate a representation.
JaKiri Posted March 1, 2004 Posted March 1, 2004 Not in 3D, no. In 2D, you can't really do it, hence the way it changes all the time.
NSX Posted March 1, 2004 Posted March 1, 2004 MrL_JaKiri said in post # : You know 3D specs? That kind of thing. Wow, that's funky. Can the same program do vectors, planes, several variable functions, etc. in 3space?
JaKiri Posted March 2, 2004 Posted March 2, 2004 It's generally used for looking for 3D irregularities in the interiors of stars!
