The apple is an asshole.

Sagan's ability to explain higher concepts was marvelous.

But how was that shadow of a tesseract developed? From an imaginary perpendicular directional projection of a cube that constitutes a tesseract, how on earth did we derive its shadow? It seems even Sagan has failed to explain this to me. So far all the explanations I found were semantic and of little value. This too was that, even if slightly better worded.

Wow, something that is such an amazing interesting subject you are saying you'd not want to learn more about because of poor sound quality from the 80s when this was recorded? You're fucked up bud.

No, as Sagan says in this video, we can see a tesseract, but it figures in a third dimension. The same you can apply in a cube. When you see a cube in the 3 dimensions all the sides are equal, but when you draw it in a paper (second dimension material) it loses the proportionality. If we could see a tesseract in the fourth dimension, all the sides would be equal, but this doesn't happen when you see a tesseract in the third dimension.

This is a serie taped in the 80's, no wonder there's a terrible sound.

I have all Cosmos series on DVD, I bought them in 2006 and it's an amazing serie. The tesseract and 4th dimension are something that make me wonder why we are stuck in a 3rd world dimension, or how the 4th dimension works? Questions with no answers I guess...

Yeah people sometimes go on about how he isnt smart and such, who cares how smart Carl Sagan is or isnt.

Whats amazing is his ability to simplify stuff. I mean if teachers in schools had this ability, learning would not only be easier but more fun.

[Daxyl]

You just saw the shadow of the tesseract, duh. Weren't you even listening to Carl?

[Nubs926]

If I am grasping this correctly, I think the best way to think about directions in the 4th dimension would be "inward and outward".

my mind was just raped
