Cybernetics

Andy Farnell recently asked me, "Do you know about the work of the Barrons (Forbidden Planet) I'm trying to get hold of any research material on these kooky pioneers of "snuff audio". If you know of anyone who has schematics of their self-destructing synthesisers please gimme a shout."

If you can jump in here please do so.

Now, my knowledge of the Forbidden Planet soundtrack extended to knowing that it was a pioneering piece of work in electronic music and that it still sounds amazing today. Unfortunately I don't even own a copy, although I do have Jack Dangers brilliant reworking. After an initial google the first place to go looking is of course Wikipedia. Here I find a page about the couple, Louis and Bebe, and their work.

It's a fascinating story and by the time I'd read that I was just as interested to know about how they worked as Andy. I noticed the reference in there to a book Lewis took his circuit building inspiration from; Norbert Wiener's Cybernetics: Or Control and Communication in the Animal and the Machine (MIT Press, 1948). A quick search on this and I found that it is still in print, see Amazon link below. Wanting to keep it authentic (and cheep) I bought a second hand copy of the second edition (1961) and awaited its arrival. (In the mean time the Forbidden Planet DVD and OST CD were added to my wishlist.)




When it arrived I found a book absolutely packed with the level of mathematics I thought I'd left behind at university and nothing in the way of circuit diagrams. I still read it in the hope of finding some insight, and struggled through the maths, which although I could just about follow and found it difficult to derive meaning from. There is still interesting material in there but something aimed at a more novice audience would have been better.

Below I've typed up my notes from reading it. They will probably only be of interest to someone reading a copy of the book themselves, someone who wants to know how much it would tell them about electronics and audio, and myself as there are a few things I wanted to research further. Page numbers refer to the 1961 edition.

Blurb: "...as readable by the layman as the trained scientist..." John B. Thurston, The Saturday Review of Literature.
p72. "We now wish to define [the intergral from minus infinity to infinity of K(tor) d epsilon (t, gamma)] The obvious thing to do would be to define this as a Stieltjes' integral, but [epsilon] is a very irregular fuction of t and does not make such a definition possible." Ha. Of course! Why didn't I see that?
Do you see what I'm up against here?
p86. On electronic circuits: "The details of its construction are more for the specialist in electrical engineering than for the reader of this book. They may be found elsewhere.¹
"1. We refer especially to recent papers by Dr Y.W.Lee."
'Recent' in this case is thought to refer to 1948.
p98 "In this book, we have avoided mathematical symbolism and mathematical technique as far as possible" Lies!
p102. Fig 2 shows a block diagram of a simple feedback circuit, much as you would find in any analogue electronics textbook.
p112. Figs 3 & 4, as above.
p114. Fig 6, as above with addition of interesting filter system. [Will add scan, please check back]
p145. Explanation and definition of a minority report as a fault finding system within parallel computing systems.
p142 a. Reference to correspondence with Bristol University (also on p199)
p142 b. Contains a lobotomy joke! You don't hear those everyday.
p146. Quotes Lewis Carol.
p154. Section about people with red hair and stutters (would this by PC today!?) plus musing on extinction.
pp158-161. Thoughts on free markets and game theory (although it is not referred to as such), and the problem with capitalism.
p162. Refers to Western exploitation of the "flesh-pot of Egypt." Funny how things don't change.
p164 & 171. Notes on chess computers. Predictions seem to have been accurate.

Incidentally, I didn't only start taking notes half way through. There really wasn't anything worth noting in the first half apart from a disparaging remark about scientific fields becoming too specialised and acoustics given as an example.

Frequently used terms I decided I ought to look up:
Gestalt
A priori
A fortiori

And finally, a reference to the Rorschach Ink Blot test inspired me to have a look for the images, as even when studying psychology I can't recall actually seeing them. The disclaimer on the above site explains why (scroll down the images if you're still curious).
