No one person invented the vacuum tube. Thomas Edison, Eugene Goldstein, Nikoli Tesla, among others were responsible.
who made the vacuum tubes
Millman's theorem
the vacuum tube
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
He would not have had a barometer. He would have had a glass tube stuck into a bowl of Mercury, with nothing in it. Because once the hole was made the vacuum would be gone and the mercury would fall back down to the bowl.It takes the vacuum in the tube to create a barometer.
There were obvious differences between the trasisitor and the vacum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transmisor was the equivalent 40 vacuum tubes. They also didn't produce heat compare it to a vacuum tubes. Conduct electricity faster and better than vacuum tubes.
Although the discovery was made of the principles for the vacuum tube around 1873 it was not put into practice until the early 1900's.
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
Yes, vacuum tubes in computers burn out. Transistors are much better. Vacuum tube computers no longer exist except in museums. Vacuum tube computers were originally made in World War 2 to calculate the positioning of antiaircraft guns. It was not necessary to know where the airplane was but where it would be when the explosive arrived. That was especially true when the Germans developed the buzz bomb going 450 miles an hour. When hundreds of transistors could fit in the same area as one vacuum tube, the vacuum tube vanished.
an electron tube containing a near-vacuum that allows the free passage of electric current.
First invented by a British scientist named John A. Fleming, although Edison had made some dsicoveries while working on the lightbulb. The vacuum tube was improved by Lee DeForest.
J.J. Thomson is credited with creating the first beam of electrons in a vacuum tube in the late 19th century. This discovery led to the development of the cathode ray tube, which was integral to the development of television and other electronic displays.
