How and why it works – a TV from the 1940s

A television receiver from the 1940s

Here is another book I found in a local car boot sale. Coming from a time when education and intelligence was assumed and the dumbing down disease hadn’t yet taken hold How and why it works is a book that does exactly what it says on the cover. It tells you how things work, and explains why they work that way using neatly labelled diagrams and paragraphs of text. Everything from how a coal mine operates to electricity generation.

The fascinating part is the section on the television receiver. According to Wikipedia, television was first transmitted in 1932 by the good old BBC but this was a mechanical system at first, eventually using an electronic scanning method by 1936. Then it all stopped during the war and wasn’t resumed until 1946. The book I have was published in 1948, and the television is introduced by relating it to a radio set and to a cinema, making it look to be a fairly new concept compared to the radio on the preceding pages which starts with “The programmes you listen to on the radio” where it’s assumed everybody knows what a radio is. I scanned the television section in as a series of images, and have also created a PDF from it.

The book is really interesting, it contains a mix of brand new technology such as the TV and very old more traditional technology like the plough, electric torch and ratchet screwdriver. It’s a snapshot of time before the transistor existed, everything electronic contains valves and there is no mention of computers whatsoever.

Tomorrow – Infantry Training and mortars in the attack.

  1. Is it me, or have you changed your theme of the diary so it looking like a newspaper now? I didn’t know that the “Daily Piku” was available in a super soaraway version..are you planning a fantastic giveaway for all your readers?

  2. Yeah, the theme I used to use was a bit old and didn’t support several new WordPress features. I like the new layout better too, it looks less like a normal WordPress blog.
