Earth as Art

bravehamster writes "There's a new exhibit at the Library of Congress displaying images taken of earth by the Landsat satellites. The exhibit displays satellite photos that have an intrinsic aesthetic quality, showing the beauty of Earth as seen from really far away. There's an article about it on MSNBC here, and don't forget to check out those fjords!"

      Do not confuse computional/mathematical representation/aproximation/generation with the real world.

      Whoa!! Your crazy way of thinking seems so new and revolutionary to me.

      Seriously, though, fjords can be approximated by fractals. To show this, all one needs to do is implement a fractal box counting algorithm to the image in question. Fractal box counting will show that the fjords have a boundary that is approximately 1.4 dimensions (rather than the typical 1-dimensional boundary of a circle or square) and thus, can not be measured with a finite 1-dimensional measure such as length. Thus the coastline length can be approximated by infinity. Everybody knows that anything remotely close to infinity is still infinity (e.g. \infty - 1,000,000,000 is still infinity), thus the coastline is infinitely long, at least in 1-D.

    1. Re:Colours? by Remus+Shepherd · · Score: 3, Informative

      The colors are not 'artificial'. Landsat 7 takes data in 7 wavebands of light, only 3 of which are the red, blue, green we can see with human vision. In the Parana River scene, we used band 4 for green. That's our 'vegetation' band, and anything with chlorophyll shows up very bright in that band, thus looking very green in that image.

      So the colors are not artificial, they're just using frequencies of light that you normally can't see.

    Like the Earth would just happen to be that nice looking from space. This just goes to prove that we didn't land on the moon because we didn't even make it into space because if we did we would have ordinary ugly pictures of the earth rather than these that were obviously done by an artist. Now excuse me but my tinfoil hat is starting to get smelly and it's tiem to change it. Now don't think I'm paranoid or anything but I don't think the government is spying on me with satellites I mean they didn't even make it into space! I need it to protect me from cancer due to the radiowaves randomly bouncing off clouds the government filled with metals and chemicals to control the weather and bounce off signals to simulate satellites (they can't launch anything into space of course). Well goodbye I hope the intelligent immortal mainframes at the FBI logging my keystrokes don't decide this is unamerican or anything and steal my heart to put into Dick Cheyney!

    A short time ago the chief chicken-littles of the International Association of Environmental Alarmists and Extreamists (IAEAE) were collectively diving under their beds over a study showing how nearly every sq. inch of the planet has been hideously despoiled by nasty ol' humanity. Well, now comes a counter-study (partly funded by Gordon Moore) which claims "46 percent of Earth is still wilderness" - a salve sure to sooth the conscience of dollar sign-blinking land developers and construction workers everywhere.

    Thus proving that, like statistics, politicians can pick a study to prove any damn thing they want. Meanwhile the truth continues to elude the media manipulated public.
