1D - it's the new 3D!Tweet it - http://bit.ly/mP3FFoFacebook it - http://on.fb.me/qtTraRminutephysics is now on Google+ - http://bit.ly/qzEwc6 And facebook - http://facebook.com/minutephysicsMinute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute!In this episode we talk about dimensions and how we know that we live in 3D (or do we?).Music by Nathaniel Schroederyoutube: http://bit.ly/pakJLEmyspace: http://mysp.ac/qtmZQj

May 16, 2012 - Is it possible to fill a 4D area with 1D line?

May 17, 2012 - I thought the formula for the "volume" of a circle was (pi)r^2

May 18, 2012 - you cant tell depth(demension) when looking through one eye. it just that you taught yourself to determine how far something is. when looking through one eye, you are looking through one eye through a straight line. but when looking through two eyes, its TWO lines towards one object. thats why it looks three dimensional!

May 18, 2012 - fail1-length2-length+height3-length+height+depthif 2D were length+width, then it would be like living on a piece of paper and looking at it at an angle, sitting on a desk... which obviously can't exist in 2D.

May 18, 2012 - You are measuring 3D in 3D, that's why you know it is 3D. If you measure 3D in 2D, you will never know it is 3D because the 3rd dimension isn't exist in a 2D space. FAIL.
derek19062 Says:
May 19, 2012 - That's the area.
MysteryR000 Says:
May 19, 2012 - Ok. But then what is the "volume" of a circle. I thought 2D objects dont have a volume
Slowatia Says:
May 19, 2012 - The '~' means 'proportional to', so the constant of proportionality (the pi) can be left out
MysteryR000 Says:
May 19, 2012 - Thank you

May 20, 2012 - How can you have a one-dimensional curve? I would think that "one-dimensional" and "curve" are a contradiction.
cschumacr Says:
May 21, 2012 - If you're going to be a smart ass, do it right. "...the 3rd dimension ISN'T exist..." Fail.

May 22, 2012 - I believe that is a cello of sorts
derek19062 Says:
May 22, 2012 - No no no.... The 3rd dimension does exist, it is that you don't know *which* one is the 3rd one... so... SUCCESS? LOL

May 25, 2012 - i know how to watch a 4D movie..... A FUCKING PLAY! Or just somehow put someone in the movie following the main characters in their seat (i just mind raped and confused myself) :D
CeonDustrial Says:
May 26, 2012 - thats a little bit complicatedfor example a line can be one-dimensional too if you can describe every position of this line by 1 coordinatebut if this line is a curve with a repetive design so you can follow this curve unit after unit, you could describe every point in 2D by just one coordinateyou mustnt think in lenght/depth/high, merely in a mathmatical way of dimension
