Procedure




FANS FOR COMPUTER!

The fans are used in the cabinets of computers and other electronic devices for refrigeration. Usually the hot air is taken from inside the device with the coolers.

When a computer accumulates heat, a combination of fans and heat sinks is used to remove excess heat from the interior of this.

When the heat reaches a certain temperature, the fan turns on automatically and off automatically if it is not necessary to use as thermal regulators.

Before, fans were extremely loud, until cause a distraction, so now most fans are fairly quiet.



If before the computer has an overhead of heat, after it can damage the hardware

Robert Oppenheimer

Robert Oppenheimer was born on April 22, 1904, into a wealthy, New York, Jewish family. They lived in an apartment overlooking the Hudson River. As a 17-year-old, Oppenheimer went to Harvard where a classmate says he "intellectually looted the place." But it was after Harvard that Oppenheimer found his intellectual passion.


In 1941 Oppenheimer was brought into the atomic bomb project. His first task was to calculate the critical mass of uranium-235, i.e. the amount of uranium needed to sustain a chain reaction.

By July 1945, Los Alamos was ready to test its bomb. Oppenheimer sent a cryptic telegram to scientists back at Berkeley: "Any time after the 15th would be a good time for our fishing trip...As we do not have enough sleeping bags to go around, we ask you please do not bring anyone with you." The test, code-named "Trinity," took place on July 16. It exploded with a force equivalent of 18,000 tons of TNT.


After the war Oppenheimer achieved nation-wide recognition as the "father of the A-bomb," and he was widely quoted as the moral conscience of those who had worked on the project.


Oppenheimer returned to academic life, but as one colleague would say, the public ordeal had broken his spirit.
