Imagining the Tenth Dimension

I came across this site in my wanderings and think it's worth sharing.
Below is the introductory video, with annotations.  Probably best to just turn off the annotations the first time through, though. roflol

I started getting fuzzy in the 6th and really vague in the 7th then I was lost from the 8th on. I need to study this more. Thank you so much for sharing this.

I read the book. There was some interesting parts in it, but taking a positivist view renders most of this stuff a little obsolete in my oppinion. At best I would say it's a fanciful intereptation, perhaps if I were in a worse mood I would say pop science foo foo.

Aye, I don't know if his way of describing it is correct, but M-Theory currently posits there are 11 dimensions.  I'm looking for an excellent video about imagining things in 4 dimensions just for the hell of it, now.  Was really good, though it was long.  A series of videos, actually.

I wouldn't argue with you about that. Still, "pop science" is as close as most of us will ever get to this sort of stuff, and I think it's an intriguing subject, even if I'll never take a university level course on it.  Approaching it even at the pop science level is daunting enough, as it is.

...M-Theory currently posits there are 11 dimensions.

From the FAQ:

 

Doesn't science (M Theory) say there are really 11 dimensions?
This question was asked a lot more during the first few months of this project, when it was launched back in the summer of 2006. It still comes up from time to time. M Theory says there are 11 dimensions, but one of those is time. This framework for discussion says that time can be enfolded back into the ten spatial dimensions, and that time for whatever dimension you are examining is the way you move from one state to another. For we three dimensional creatures, we think of time as being in the fourth dimension. A two-dimensional flatlander would think of time as being in the third dimension. In any case, time is only a limited way of viewing the full dimension that it resides in.

Likewise, some people wonder why this project doesn't spend time talking about Calabi-Yau manifolds. There are some important tie-ins with this project to concepts from string theory that are worthy of note: for instance, string theorists are saying our reality is created by the interaction of a seven-dimensional brane and a three-dimensional brane. The idea from the Imagining the Tenth Dimension project that the basic laws for our three dimensional reality are defined at the seventh dimension could be thought of as a way to tie this in. Likewise, the idea that the higher dimensions are curled up down at the planck length and therefore invisible to us ties in quite easily: our "line of time" is being constructed from the available probabilistic choices at the fifth dimension, one planck length at a time. This means that, like the flatlander on the mobius strip, our line of time is actually twisting and turning in the fifth dimension but we are unaware. Imagining that the higher dimensions could also have a shape that we see as a Calabi-Yau manifold is really not that big a stretch: a Calabi-Yau manifold is just another way of visualizing the higher dimensions. It should still be noted, though, that string theory is not the main focus of this project, and the math tools that string theorists use are inherently vastly more complex than the way of visualizing the higher dimensions that we are playing with here.

Ah, I'm just used to calling time a dimension. I read a lot of stuff that doesn't neglect to call things "space-like dimensions" and "time-like dimensions."  But for simplicity's sake, time is a dimension.  It's easier to think of it as such because it can apparently be altered as one, and isn't experienced universally, just like space.  But I won't argue with the FAQ, time isn't a spatial dimension.
