A team of University of Michigan researchers has recently created a set of electron microscope images of carbon nanotube structures depicting images of US President-elect Barack Obama. John Hart, leader of the research team says it wasn’t a political statement, but an attempt to draw attention to what is possible these days with nanotechnology, and imaging at the very small scale. I’ll take him up on this invitation and share with you some other images of very tiny things in our world. For visualizing the scale, most measurements below are in microns – one micron is a millionth of a meter – human hair is approximately 100 microns thick. Rime on a columnar snow crystal. Contact between the snow crystal and the supercooled droplets in the air resulted in freezing of the liquid droplets onto the surface of the crystal. Observations of snow crystals clearly show cloud droplets measuring up to 50 microns on the surface of the crystal.

how does alan do it?
