"We've been working on semiconductor materials for years, gradually moving down the periodic table, looking for materials that behave well but also do interesting or unexpected things," said Ravichandran, the Philip and Cayley MacDonald Endowed Early Career Chair and associate professor in the Viterbi School of Engineering at USC.

“It became very clear very quickly that this was like watching a reality show like ‘Love Island’ or ‘Big Brother,’” said Cayley Christos, a field producer on “Penguin Town” and co-owner at production company Red Rock Films.

Cayley is a minor but not insignificant figure in the history of science and technology; but there is no doubt that our sense of his significance derives entirely from hindsight.

It is perfectly sensible to say that Cayley laid the foundations of modern aeronautics.
