Summary
This week Richard looks at the history embedded in Hawaii's Keck Observatory. How could a sand-blaster, a Cold War spy gadget and the invention of refrigerators have led to the creation of this super telescope? And using just a satellite dish and some foil, is it possible to set fire to a boat? Richard experiments. (From the UK, in English) (Documentary Series) (Part 2 of 4) G CC WS
