During the summer before medical school, I was working with the Zeiss EM 9A electron microscope at the Biological Labs in Cambridge. I had finished an honors project doing electron microscopy, and was allowed to continue working on the device. The bargain, however, stipulated that I keep the instrument aligned and functioning optimally. That was well nigh impossible. It had a poorly designed double cup condenser system that was always drifting out of mechanical alignment. Each day I toiled for 1-2 hours just to get the image on the screen.
While I was working in the darkened EM room, Dick McIntosh, my research project advisor, came into the room with a little blonde slip of a girl. He explained that she was coming to work as a technician, and that one of her chores would be to take over care of the Zeiss. She was lovely, and I stammered out something about being willing to help her to learn about the device.
They left, and continued their tour. I sat in the warm glow of the experience, but later chuckled to myself. I could not imagine that cute little blonde managing to deal with my microscope.
