Seeing small objects is no simple task, but it is an essential one for scientists from fields as diverse as astronomy and nanotechnology. In order to see tiny things, we need to both magnify them and keep their fine details apparent. Which is more important, raw enlarging power or precise detail?To help me explain, I …
Zooming in on the Nano World: Limitations and Breakthroughs in Light Microscopy
The idea that an image is worth a thousand words applies just as much in science as it does in other contexts. Using images, scientists can convey complex information more quickly and often more clearly than is possible using words—which do you prefer: words (left) or a picture (right)? Today I want to talk about …

Nano-Koosh-balls: What They’re Good For and How I Made Them.
We talk a lot about nanoparticles, which are nano-sized and nearly spherical. But, the shapes accessible in the nano-world are plentiful! For example, I recently made these! (click for larger images... DO IT!) I like to call them “nano-Koosh-balls,” because of how closely they resemble the children’s toy of the same name. These nano-Koosh-balls are …
