Saturday, October 09, 2010 7:57:46 PM does this work? don't you have to separate with the units whole?

Tuesday, February 23, 2010 2:02:59 PM I Understand this. But 64 cant be 65, or 64 would be 65. But 64 is just 64. And thats all.

Monday, February 15, 2010 10:23:55 PM The easiest way to explain this is that in the final configuration, the two lines comprising the tops of the green and orange shapes do not together form a straight line. The slope of a line is the rise divided by the run. The line atop the green triangle has a rise of 3 and a run of 8, and therefore, a slope of 0.375. The line atop the orange shape has a rise of 2 and a run of 5, and therefore, a slope of 0.4.This results in a gap in the shape of a very thin parallelogram with an area, as MrRubik explains, of 1 unit. The width at its widest  in the center between the green and red triangles  is approximately 0.117 units. (1/sqrt(73))

Monday, February 15, 2010 5:24:24 PM whoever thinks this works is dumb, when you multiply something it wont make the same answer as something else, 8x8=64 5x13=65

Monday, February 15, 2010 12:53:31 PM this one works because its assumed that the lines are all perfectly straight, they aren't.
They are. That's not how this works. Read the comments.

Monday, February 15, 2010 10:31:50 AM @TKD master the gap in the middle DOES matter it's very thin, but long so it makes 1cm^2. check out murderous maths.co.uk if u dont believe me.

Monday, February 15, 2010 8:05:01 AM "The two "triangles" are slightly concave, so the second square has a minuscule gap in it."a gap in the middle wouldnt matter, it'd still be 5x13. they very slightly changed every slope, very very very freaking slightly. with many different slopes, they can change each one by just a hair and make it all fit.

Monday, February 15, 2010 5:56:48 AM Lolwut? Why do we even try to understand math?

Monday, February 15, 2010 5:54:25 AM 1/3*3 only = 1 when 1/3*2 is put to decimal places.i.e. 0.33333' + 0.33333' = 0.66666', which is deccmalised to 0.66667, so + 1/3 = 1 so this video is mathematically wrong as generalizations are being used to solve it.

Sunday, February 14, 2010 11:23:14 PM well .99 equals 1 because 1/3 equals .333 (repeated). 1/3*3=1 and .333(repeated) * 3 = .999(repeated).
Yep. 0.999(repeated) does equal 1. Its called math.

Sunday, February 14, 2010 8:01:27 PM Old geometry joke that requires you to assume precision that the experimenter is counting on you assuming. Slopes of those areas do not align.

Sunday, February 14, 2010 7:54:17 PM There is no sliver of a gap  It's because when the pieces are changed around, the slope gradually takes away more white space
No. Just no.

Sunday, February 14, 2010 6:43:03 PM There is no sliver of a gap  It's because when the pieces are changed around, the slope gradually takes away more white space (the space in the little squares)... Wasn't there another similar post like this one?

Sunday, February 14, 2010 6:31:51 PM again the slopes arent the same so it wouldnt match perfectly
