Bacteria on the head of a pin
The subject is a pin with bacteria on it. Progressively the magnification increases to the point that resolution is exceeded with Scanning Electron Microscopes and we shift to the higher resolution of Transmission Electron Microscopes. We increase in magnification until we resolve columns of atoms in various crystal planes in the magnetosome of a magnetotactic bacteria.
