Nov 16, 2009 - anybody heard of the movie, the fourth kind? it reminded me of this, its like a creature from the fourth dimension interacting with people, from within.

Nov 17, 2009 - klober-- ironic to say "use your own brain" and promote religion in the same sentence. what religion exactly are you talking about here??? i wish being atheist was a lot "cooler", we could certainly use more critical thinkers on this rock.

MovieTheaterLad Says:

Nov 17, 2009 - So you're saying all people who follow religion are stupid? Way to be racist, there. Carl Sagan would be disappointed in you.

Nickopops Says:

Nov 17, 2009 - lol, how is that racist?

Nov 18, 2009 - This is the vid where I got introduced to carl sagan. It was as if he had moved onto a higher dimension and was picking me up and showing me around. =) R.I.P sagan!

Nov 18, 2009 - He's the uncle we wish we all had.

jackofclubz Says:

Nov 18, 2009 - I like the way he said "congenial square".

Nov 18, 2009 - Knowlege have nothing to do whit Believing...If we haved stuck to believing, a flat world will still be our flat world, but difficult to understand to the main human....

MovieTheaterLad Says:

Nov 18, 2009 - He's saying people who follow religions "don't use their brain" and implies that they aren't "critical thinkers". Judging people based on their faith is a form of racism as much as judging people based on their skin color or ethnicity.

Nickopops Says:

Nov 18, 2009 - i'm not sure you understand what 'racism' means. treating people differently in any fashion because of their race is racism. nothing else is racism. judging people based on their religion is prejudiced, but it's not racism.

Nov 18, 2009 - racism needs to involve race. you obviously know what you're talking about movietheaterlad

myysticranger Says:

Nov 19, 2009 - This guy sounds like agent Smith. He must be the Idea where Hugo weaving got his Agent Smith on

alexr29 Says:

Nov 19, 2009 - @MovieTheaterLad You are referring to religious prejudice not racism.

MovieTheaterLad Says:

Nov 19, 2009 - Meh. I was always told it counted as well. Oh well. Still mean, nonetheless.

Nov 19, 2009 - People just use racism as a blanket term for all terms of ignorance.

Nov 20, 2009 - Is there a next part to this video?

MrBlamemeforit Says:

Nov 21, 2009 - As he said.. if any human were "taken" by a fourth dimension creature into fourth dimension we wouldnt be able to understand what we see.. The flat creature couldn't explain where up was. Maybe i am dead wrong:P

Nov 23, 2009 - This is another mathematician's stupidity game. At 1:01 ... lol, lets ignore that!

callumnik117 Says:

Nov 23, 2009 - ok, you physically represent the 2D world in our 3D world. using physical objects.

jukawizard Says:

Nov 23, 2009 - Carl Sagan rocks!

psilocyberspaceman Says:

Nov 23, 2009 - Exactly. it is a stupid mind game. How can something in a 2D world even see ahead? Taking about 4th dimension et cetera -- is like hearing religious people rant about god. Unfortunately, mathematicians cannot even define a point, a line, or a plane.

rkyeun Says:

Nov 23, 2009 - You need to learn some math. We defined points, lines, and planes in like, first grade. A point is a particular coordinate in space, and ordered series with a single constant value for each mutually perpendicular line permitted in that space. A line is the straight path between points in two different places, continued infinitely in either direction beyond those points. A plane is the flat surface containing two lines that are in different places, extending out infinitely.

rkyeun Says:

Nov 23, 2009 - Something in a 2D world (if we assume such a thing exists) would see (if we assume the two-dimensional world has two-dimensional light) ahead of it by looking forwards. It can rotate in a circle to be facing any direction you could draw an arrow on paper. If it has two or more eyes it will be able to see depth to judge how far away from it on that sheet of paper other objects drawn on the sheet of paper are.
