On the continuum line from basic to applied research, is it possible to identify an area at the point at which you're likely to be able to do that?
It seems to me that sometimes with basic research, and with discoveries in basic research, when you're trying to identify market opportunities, initially that may be difficult and it may take time for it to become clear.
One discovery that occurs to me in its development—where that may not be the case so much, I don't know—was the digital sensor for cameras. It took quite a while after it was first discovered—I think it was at MIT—before they started making cameras out of that. There may have been other discoveries that led to it that were key, but at that time were not.
That's the question about—
