Phase contrast was not discovered while working with a microscope, but in a different part of optics.

How quick are we to learn: that is, to imitate what others have done or thought before. And how slow to understand: that is, to see the deeper connections.

On April 8, 1982, I was alone in the electron microscope room when I discovered the Icosahedral Phase that opened the field of quasi-periodic crystals.

In the autumn, Bradley came out with his policy positions and we entered a compare-and-contrast phase. We're in that same position this week.

Fiber optics got slammed last week,

The refs are under a microscope. So we can't blame them.
