By Dr Pieter Kok
Pieter started his talk by explaining the wave nature of light and the problems in resolving smaller and smaller features in distant objects. This involves using larger and larger telescopes, but he told us of other ways in which to get the resolution required.
He gave us a brief sketch of the development of quantum optics and showed diagrams explaining this. He touched on his research into quantum mechanics and said once the James Webb telescope was launched and up and running, our understanding would be greatly enhanced.
His talk was well received and he was given a tour of the observatory and was suitably impressed with our set up.
PS The James Webb telescope’s launch has been put back to 30 March 2021!!
