The images below represent just a tiny sampling of the marvels that scientists are discovering at the nanoscale. Many of them are from the online
gallery of Harvard physicist Eric J. Heller, who generates them in the course of studying wave behavior and chaos in the quantum realm. But they also include one example apiece from the work of Vincent
H. Crespi at Pennsylvania State University; Chad Mirkin at Northwestern University; and Ghim
Wei Ho and Mark Welland at the University of Cambridge. |
