GUEST HOST: PETER REGAN

Stone is cutting thin sections of Andromeda to prepare slides for the electron microscope. They watch the operation on a magnified screen.

“That’s a good slice,” says Stone as a small green square appears on the micro blade. “Too thick,” he adds.

More slices appear on the blade.

“I’m setting it at eight hundred angstroms, Hall,” says Stone, adjusting a few knobs on the device. “I’m going to a higher magnification.”

A rainbow of slices appears on the screen. “Now, we’re getting somewhere,” says Stone.

“Yeah,” says Hall. “A piece can’t be more than a few molecules in depth.”

“That’s the one! That silver one,” says Stone, as another slice appears on the screen.

“THIS IS A VELOVAC ALERT, ALL LEVELS,” says an announcement. “THIS IS A VELOVAC ALERT.”

Stone uses tweezers to put the slice into a small metal container.

“ELECTROMAGNETIC WAVES ARE NOT REGISTERING ON THE D-I-R,” says another announcement.

Stone puts a tiny cap on the container.
