Note the part where the biologists tell him to make an electron microscope that's 1000X more powerful. Then note what technology was used to scan these images.
I think it's actually "What you should do in order for us to make
more rapid progress is to make the electron microscope
100 times better" and the state of art at the time was "it can only resolve about
10 angstroms" or I guess 1nm. So 100x better would be 0.1 angstrom / 0.01 nm.
