Mathematical Lego Sculptures

    Lego people can walk sideways on buildings?? We must make them our leaders!

      THEY'RE NOT LEGO PEOPLE! The polically correct term is "MiniFig". Please refer to them as such since "Lego People" is a demoralizing term.

  2. Figure Eight Knot by abigor · · Score: 5, Insightful

    That is totally amazing. And for what it's worth, I think it's a worthwhile use of his time (not that my opinion on how someone uses their time matters, but whatever). I don't know, to me for some reason non-trivial acts of creation like this seem to touch whatever it is to be human -- our creative endowment is one of our signature traits, I think. What impulse would drive this sort of creative urge, to create beautiful mathematical shapes out of Lego, of all things? Whatever it is, it's mysterious, and it wasn't a waste of time. That figure eight knot is incredible.

    Very, very cool.

    Now show me a hypercube and I'll be really impressed.

      That's easy. Take a 4-cube. Pass it through 3-space, and what you'll see is an infinitely small cube at the point in the center of the 4-cube which will then grow to the cross-sectional size of the 4-cube, and shrink back down. Not too hard to wrap your head around. Tesseracts are a totally different matter...

      I disagree. That nicely describes what happens with a sphere, but not so much with a cube.

      I guess it depends on how it's passing through 3-space. The best way to imagine this stuff is to imagine a 3-D object passing through 2-space. If you pass the cube through corner first, you'll get something like what you describe, except the cross sections will be triangular most of the time. Edge on, you'll get rectangles.

      Face-on, your 2-space will see nothing until the 3-cube hits it, then the 2-space will see a square just sitting there until the 3-cube is all the way through.

      What's the difference between a tesseract and a 4-cube? According to Eric Weisstein, it seems they're the same thing.

  4. Other lego sculpture sites by Juhaa · · Score: 5, Informative

    I love Andrew Lipson's Math site, thought it was on slashdot for a while. If you like to see other such sites check out Eric Harshbarge's Lego page (cool stuff like wedding cakes and skyscrapers), Henry Lim's totally awsome lego sculptures, he's even got Natalie Portman (Not naked, and next to the petrified beethovan). BTW, Eric's got a very interesting page on on San Mononoke (more on those).
