Two young men from up in Minnesota were looking at a Sears catalog and admiring the models.
Ole says to the Sven, "Have you seen the beautiful girls in this catalog?"
Sven replies, "Yes, they are very beautiful. And look at the price!"
Ole says, with wide eyes, "Wow, they aren't very expensive. At this price, I'm buying one."
Sven smiles and pats him on the back, "Good idea! Order one and if she's as beautiful as she is in the catalog, I will get one too."
Three weeks later, Sven asks his friend Ole, "Did you ever receive the girl you ordered from the Sears catalog?"
Ole replies, "No, but it shouldn't be long now. I got her clothes yesterday!"

Harry Boot

Born 29 Jul 1917; died 8 Feb 1983 at age 65.Dr Henry Albert Howard "Harry" Boot was an English physicist, who worked with John Randall developing the cavity magnetron, the microwave-generating device used in radar. This made a major contribution to winning WWII. Earlier magnetrons made in the 1920's gave low power output. By Feb 1940, advances by Randall and Boot in the design of the small-sized cavity magnetron, produced centimeter wavelengths at much higher power, which allowed radar to detect smaller objects. In turn, this more compact equipment with a smaller antenna permitted easy mobile installation of high-resolution radar in aircraft.«
