We have no standard technique to do this now. But let me argue that it is not as difficult as it first appears to be. We can reverse the lenses of the electron microscope in order to demagnify as well as magnify. A source of ions, sent through the microscope lenses in reverse, ...
eld theory until the rather dubious (in my opinion) mathematical technique known as renormalization arrived on the scene to bail out the theory. I'm certainly not going to discuss renormalization in any detail in this simple write-up, but I can give you a taste of what the approach ...
