Radar worked by sending out a radio wave and analyzing the reflected wave after it bounced off any objects in the air. The rectifier's job was to translate the reflected signal into the direct current necessary for visualization on the screen.

Radar can detect a speeding car and track a satellite. Most importantly for meteorologists, radars can detect all sorts of atmospheric phenomena.]]> 2023-04-03 13:53:18 UTC https://padlet.com/2002070339/4yhz19rqvbdbes1i/wish/2542260809 Who invented radar?

Radar First Used:
Both the Allies and the Axis forces employed this ground-breaking new radio-based detection and tracking technology during World War II. This technology had independently developed in a number of countries throughout the middle of the 1930s. Radar systems were operational in both Germany and Great Britain at the start of the war in September 1939.]]> 2023-04-03 14:47:53 UTC https://padlet.com/2002070339/4yhz19rqvbdbes1i/wish/2542350979 How was RADAR IN WW2 created(Ashley) https://padlet.com/2002070339/4yhz19rqvbdbes1i/wish/2545099228 1940s radar relied on a semiconductor crystal, or "rectifier."

(Andy) https://padlet.com/2002070339/4yhz19rqvbdbes1i/wish/2546257108 When was AI invented?
1940-1960: Birth of AI in the wake of cybernetics
The period between 1940 and 1960 was strongly marked by the conjunction of technological developments (of which the Second World War was an accelerator) and the desire to understand how to bring together the functioning of machines and organic beings.
AI first use?
The earliest successful AI program was written in 1951 by Christopher Strachey, later director of the Programming Research Group at the University of Oxford. Strachey's checkers (draughts) program ran on the Ferranti Mark I computer at the University of Manchester, England.

From the outset, there were two competing approaches. One used formal rules to manipulate symbols, a logic-based approach not at all based on biology.
