I gave this excellent little talk on light at the Odditorium in Brighton a couple of years ago and only discovered it to be online recently when a listener contacted me to ask about the tattoo mentioned in the talk. I sent him a picture of it and he sent me the link, which I now send to you. The curious events in their introduction occurred before my arrival so I cannot enlighten on that front.
The Mystery of Light with Gregory Sams
This episode starts with a crash, after an eclipse and power cut in the studio leave our presenters stumbling around in the dark while Mr Mounfield later reveals himself to be a Zoroastrian. It all proves however, to be a perfect link for their guest, Gregory Sams, who puts forward a compelling argument for the sun, stars and universe being far more intelligent than conventional science would have us believe.
