A team of University of Michigan researchers has recently created a set of electron microscope images of carbon nanotube structures depicting images of U.S. 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 Squid Suckers 400 microns a weevil its snout is just over 100 microns wide a leaf from a Black Walnut protrusion at center is just over 50 microns A Microelectromechanical system (MEMS) gear train larger gear at center is about 80 microns Microalgae Rime on a columnar snow crystal Pollen largest one at center is nearly 100 microns wide brain cells melanoma cell |
