I have seen many things in Lego. Batman, the entire Star Wars Saga, an inkjet printer (made by Google founder Larry Page). Well, if pop culture can be rendered in Lego, they might as well do something educational, hence the Large Hadron Collider!
Created by a physicist at the Niels Bohr Institute in Denmark, Sascha Mehlhase spent $2,600 of customized bricks and 33 hours to assemble 9,500 bricks into a model of the ATLAS detector, one of the seven particle detectors in the LHC. The ATLAS detector is 25 meters in diameter. Its Lego counterpart is .6 meters tall. The scale is 1:50, or perfectly life-sized for a Lego figure.
Now, if only someone can render the entire 27 km length of the LHC in Lego.

While we are on the subject of Lego (can you sense that I have a lifelong love for this toy?) here are 6 inventions made of Lego that actually work! http://www.tecca.com/pictures/lego-inventions/1/#TeccaPhotoID=6. I see a twin-lens camera, a robot arm and a 3D milling machine. Go Lego!
