Were any of the Christmas Lectures copied by BBC Enterprises for overseas sales in the sixties and seventies? Because that is the only realistic way these missing episodes could be recovered. If they weren't copied then there is very little chance of getting anything back unfortunately. It's really clutching at straws to presume people would have had a very very expensive video machine...and recorded Christmas Lectures episodes on very expensive tape! More likely might be audio recordings that could have somehow been recorded from TV and survived in that form.

They want these:It's definitely not likely, but technically possible on the CV2000 and over time, more models. They'd have done even better to specify audio tapes. Many people recorded TV audio at home; although more often with a microphone than a line-out, and lots must have simply been destroyed over time because no-one cared.

It's the sort of material a science teacher might want for reference, so there's a good chance of audio.
Did one of the George Porter episodes demonstrate a limited kind of time reversal using a spot of dye in a jar of thick liquid? The dye was smeared by rotating a paddle in the liquid, and then the spot was pushed back together by reversing the rotation. If that was a 1969 Christmas lecture, then I saw it in Australia.

Brilliant, Sue! I've found a friend used to audio record Julius Sumner Miller's lectures off television, so this looks like a great avenue.

Thanks, Martin. The fearsome Sumner Miller's show "Why Is It So?" was an unforgettable experience. And one which resulted in lots of milk bottles being returned with boiled eggs inside them.
The Royal Institution has several of the existing lectures available on line, including "Engineer Through The Looking Glass", the follow up to "Engineer In Wonderland".
