"I've decided that what interests me most is that you can only capture the light at a certain time. But after that, five minutes after that, then it's a different thing. So if you don't have the right aperture, you've missed it. Of course, you can correct it in the lab. But not really."

In 1945 J.A. Ratcliffe ... suggested that I [join his group at Cavendish Laboratory, Cambridge] to start an investigation of the radio emission from the Sun, which had recently been discovered accidentally with radar equipment. ... [B]oth Ratcliffe and Sir Lawrence Bragg, then Cavendish Professor, gave enormous support and encouragement to me. Bragg's own work on X-ray crystallography involved techniques very similar to those we were developing for "aperture synthesis", and he always showed a delighted interest in the way our work progressed.
