10th (and other) Dimensions

[vexx]

Hi,

I saw this animation and thought it was interesting/awesome since i didn't know much about the other dimensions.

Headache.

Interesting though, haha.

[vexx]

haha, i know, i was kinda confused by dimensions 6&9 particularly.

The videos on this website have stunning graphics, and can also teach you a thing or two: http://www.dimensions-math.org/Dim_E.htm

^oooh thanks ahmad, i'll check this out soon.

It's pretty interesting. I think it's fascinating how an 11 dimensional space was proposed to combat some of the difficulties with String Theory.

This is very interesting.

Dimensions in physics is different to dimensions in maths. In physics the 4th dimension is time, whereas in maths it really isn't.

so in maths the 2nd dimension can be written as {(1,0),(0,1)}, i.e. I can use these points to represent any point in the 2nd dimension. You can also write it as {(1,1),(1,-1)} so you can look at the second dimension from different view points.

Anyway I hope to understand this much better by the time I finish my major.

^ oooh, how interesting, so are you doing a lot of dimensions in your mathematic physics major?

i'd love to do some quantum mechanics at uni, i wonder if it's possible to do, or would it be more integrated into a physics major & not a single subject


edit; Cthulhu- those notes look so confusing haha.

I think most universities offer quantum physics at 2nd and 3rd year, so you might be able to take the subject if you've studied 1st year physics and mathematics.

I <33333 quantum physics.

^ awesome. yeah it seems so interesting from what i've read. i'm not sure if it's available in biomed though even though theres physics/math core...

Something like that. One model of 3D space with time is Minkowski space, which is just with a very strange pseudo inner product.
In maths, it's pretty normal to work in dimensions, where is an arbitrary positive integer. The difference between mathematicians and physicists then is that physicists work in a fixed dimensional space (in this case, ), and that they put further structure on this space (such as pseudo inner products, norms, metrics, etc).

I only know of the super dimension.

I.e, SUPERRRR DIMENSIONALLLL FFORRRRRRRTRESSS.

lol I've noticed lately with LaTeX, you can't put it around single letters =.=

Fixed Weird though.
