Invention of the magnetron -an essential component of radar and microweaceovens.
http://www.marconicalling.com/museum...-i=64-s=6.html
"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 |

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

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

MC,
You fool. To garner the fat one's interest you should mention the magnetron is the most used device for cooking food (if you consider it "cooking"). Mention it is the quickest and most efficient for heating quantities of food. Lawrence Welk "The_navigator©" wrote in message ... You mean you didn't learn something not to your your liking?

What can you do if he doesn't know what a microwave is? He probably
thinks it's a mexican wave in his formarium. Cheers MC MC, You fool.

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.

Many ppl think that the atom bomb was the most significant hi-tech invention during ww2 but it was really the cavity magnetron which really made radar (and micro-wave ovens) practical. HOWEVER, I will sorta put up two quotes from the eminent brit physicist Lord Kelvin of the 1890's. "These so-called X-rays will be shown to be a fraud" this is my fav since I make x-ray optics. Kelvin also reccomended that young men not enter physics as "all important physics has been done except for a few minor problems in electromagnetic theory" (or something like that). It was those few problems in E&M theory that led to relativity theory (Equations for E&M waves were not invariant under Galilean transformation. Einstein used the Lorentz transform that had been suggested to explain the Michelson Morley experiment to make them invariant). In both cases, the Brit (Kelvin) was trumped by Germans. Kelvin was still one of the greats, in spite of being wrong. Now, how does this apply to sailing? |

Keep trying.

Do you have those X-ray specs, too? I've got some, and I've tried wearing them at Hooters, but everything is just blurry, and I get a headache. I don't think they really work. Hero@Horvath I don't spend my money on food. I spend most of my money on women, porn, booze, and recreation. The rest of it I just waste. |
