Mosaics can enchant humans with gestalt beauty, but for many other creatures, their worth transcends aesthetics. Repeating patterns of tilelike motifs adorn insect eyes, shark mouths, sunflower heads ...

A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self-repeating ...

In a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed Hofstadter’s butterfly — a fractal pattern in electron energy levels that was ...
