"Roger, at Cornell University they have an incredible piece of scientific equipment known as the Tunneling Electron Microscope. Now, this microscope is so powerful that by firing electrons you can actually see images of the atom, the infinitesimally minute building blocks of our universe. Roger, if I were using that microscope right now, I still wouldn't be able to locate my interest in your problem. "
Frasier

"Scan not a friend with a microscopic glass
You know his faults, now let his foibles pass"
Frank Crisp

"One story that the Prof.(Oakley) used to tell, is that when the SEM was being considered as a commercial product, a group of Marketing experts were sent out to make an evaluation of the number of SEMs that could be sold. ...they came back with probably between 6 (six), and 10 (ten) would saturate the market!"
Bernie Brenton

"I would like to try and impress upon you while I am talking about all of these things on a small scale, the importance of improving the electron microscope by a hundred times. It is not impossible; it is not against the laws of diffraction of the electron. The wave length of the electron in such a microscope is only 1/20 of an angstrom. So it should be possible to see the individual atoms. "
Richard P. Feynman
December 1959


"I believe that you have to take some intelligent risks to advance science."
Pratibha Gai

"In case there are people out there who still think TEM is just taking pretty pictures to fill up one's bibliography, please stop, pause...and digest the extraordinary intellectual demands required of the microscopist in order to do the job properly: crystallography, diffraction, image contrast, inelastic scattering events, and spectroscopy.""
Gareth Thomas

"We replaced the wave length of the light by the wave length of electrons at an accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging aperture of 2 X 10-2 rad...we came up with a resolution limit of 2.2 Å ."
Ernst Ruska
