Then you started talking multi dimensions...reminding of my favorite physics trick:<BR/><BR/>a2 + b2 = c2 descibes a triangle that might well be in flatland.<BR/><BR/>Similarly, a2 + b2 + c2 = d2 describes the diagonal distance in a box (front left top corner to the back right bottom corner) - a <BR/>3 dimensional object.<BR/><BR/>If a2+b2=c2 and a2+b2+c2=d2, then <BR/>a2+b2+c2+d2=e2, discribing the fifth dimension. Abracadabra!

I was also thinking how people describe hearing God through a voice in the heart, and the Flatland idea makes it possible to think of that sort of literally.dancing dragonhttps://www.blogger.com/profile/01663876095374302735noreply@blogger.comtag:blogger.com,1999:blog-4003239.post-34998207768644530662008-02-07T19:31:00.000-08:002008-02-07T19:31:00.000-08:00We do live in a (macroscopically) four-dimensional...We do live in a (macroscopically) four-dimensional world: 3 space dimensions and one time dimension, or 3x1. Similarly, Flatland has three dimensions: 2x1. The difference between time and space is that time only goes forward. Mathematicians who study the partial differential equations modeling nature talk about boundary-value problems -- space can be bounded on both sides; and initial-value problems -- time can be given a boundary only at the beginning.<BR/><BR/>Thinking about how 3D objects move in time can give you some idea about how to think in 4D; just pretend that the usual rules of time don't apply.<BR/><BR/>Take Flatland and the safe, for example. The safe is a square, and the coin is a disc in the safe. Now add the time dimension. The square becomes a rectangular prism (the prism dimension being time), and the coin becomes a cylinder. Now, wiggle the safe all you want: you can't get the coin (the cylinder) to leave the safe (the prism) without going through the temporal wall of the safe. But if you break the rules of time, you can get the coin out. One way is to suppose the coin blinks in and out of existence as time passes (but it's in the same place whenever it exists). The 3D picture for this is a cylinder with chunks taken out of it. When the coin blinks out of existence, move the safe. (Now the rectangular prism is no longer a prism: part of it is sheared.) When the coin blinks back into existence, it's outside the safe. A second method is to go back in time. The coin ended up in the safe at some earlier time, so go back there, move the safe to a different location, and the coin ends up outside it (at the expense of breaking causality).<BR/><BR/>Once you see the picture for these scenarios in Flatland, you can transfer them to our macroscopic 3x1 world. And now you have a way of thinking in 4D.Anonymousnoreply@blogger.com
