Invention of the magnetron -an essential component of radar and microweaceovens.

"In Britain the Royal Navy had for some time been aware of the importance of ultra-short wave radio for inter-ship communication and early in the Second World War had contracted with Birmingham University to conduct research into transmitting and receiving valves functioning at 10 centimetres. Research conducted by two young scientists assigned to the project, John Randall and Harry Boot, resulted in the creation of the cavity magnetron, which was small enough to be held in one hand, yet could produce 400 watts of power at the required 10 centimetre wavelength, over 100 times more than the most powerful valve then in existence, the klystron. In August 1940, at the height of the Battle of Britain, the cavity magnetron was taken to the USA by a small party of scientists and service officers, led by Tizard. The Americans were so impressed that production of the British cavity magnetron began within weeks." I'd say the US knows a gift when they see it? Cheers MC |

Congrats, MC!!!

I agree. MC's so dull that Brasso uses him for the 'before' picture.

I'd say that supports exactly what I've been saying. Given the timing, it was certainly a
huge improvement, but it was one of many necessary to create a workable system. Your link makes it sound like they invented the cavity magnetron, which is certainly not true. And don't forget, at this point in time, the US wasn't even in the war. We were spending billions of dollars developing Radar to save Britain.

Bwhahahahha. Who built the first radar array? Did the US even have an
array? Cheers MC Jeff Morris wrote: We were spending billions of dollars developing Radar to save Britain. |

You mean you didn't learn something not to your your liking?

How about this;
Boston 1873: A man about forty-six years of age, giving the name of Joshua Coppersmith, has been arrested in New York for attempting to extort funds from ignorant and superstitious people by exhibiting a device which he says will convey the human voice over metallic wires, so that it will be heard by the listener at the other end. He calls the instrument a "telephone", which is obviously intended to imitate the word "telegraph", and win the confidence of those who know of the success of the latter instrument without understanding the principles on which it is based. Well-informed people know that it is impossible to transmit the human voice over wires as may be done with dots and dashes and signals of the Morse Code, and that were it possible to do so, the thing would be of no practical value. The authorities who apprehended this criminal are to be congratulated, and it is to be hoped that it may serve as an example to other conscienceless schemers who enrich themselves at the expense of their fellow creatures.

No, I don't recall seeing one. But I did spend a lot of time in the "temporary buildings"
that housed the old RadLab - they were finally torn down a few years ago. This reminds of the 1952 British movie "The Sound Barrier" which sort of claims that Geoffrey de Havilland broke the sound barrier by "reversing the controls." In Chuck Yeager's words it was "utter shuck from start to finish." "Donal" wrote in message ... "Jeff Morris" jeffmo@NoSpam-sv-lokiDOTcom wrote in message ...

In 1940 the American technology was the equal of the British for the longer 1 meter
wavelength. But they were not deployed in the same numbers as the British. I'm not saying the British were not major players in this field. But you implied that Radar would not have existed without the British - this is clearly a myth! "The_navigator©" wrote in message ... Bwhahahahha. Who built the first radar array?
