School spirit comes in all sizes, it seems.

An engineer from the University of Utah has created what is possibly the world's smallest college logo. Measuring just 70 microns across, the medallion is gold-on-silicon and was made by Randy Polson, a senior optical engineer in the Physics and Astronomy department, using lithium-beam lithography. Essentially, Polson used a thin beam of electrons to meticulously etch gold onto the surface of the silicon.

This nanoscale display of school spirit is actually the width of a blonde human hair. (Blonde hairs tend to run smaller than brown, black, or red strands.) But is it really that small? Let's put it this way: That lightly colored fine line that encircles the emblem? That's 20 nanometers thick, equivalent to 75 gold atoms strung together.
