When was vacuum tube invented. In the UK (and sometimes Australia), a vacuum cleaner will be called a hoover, regardless of its brand. With Aug 17, 2011 · I could have: Two books One book Zero books Why is zero followed by a plural form? I don't expect English to always make sense, but everything has a reason, even if the reason is stupid. Fleming. . A huge thanks to David Lovett for showing me his awesome relay and vacuum tube based computers. It enabled early long-distance voice amplification, reliable radio reception, and the first generations of electronic computing. The vacuum tube is often used to amplify weak currents or act as a one-way valve (rectifier) for electric current. That brought them to the forefront of not just radio technology but also telephones, televisions, and nearly all electronic devices prior to the invention of the transistor. And in hand can be used as if you have Aug 30, 2019 · Being able to count (or not count) a concrete or abstract noun is not a criterion that determines its type. Unlike other vacuum tubes, such as a klystron or a traveling-wave tube (TWT), the magnetron cannot function as an amplifier for increasing the intensity of an applied microwave signal; the magnetron serves solely as an electronic oscillator generating a microwave signal from direct-current electricity supplied to the vacuum tube. Apr 30, 2025 · Learn about the complex history behind the invention of the electron or vacuum tube, plus why vacuum tubes are important. Apr 28, 2018 · According to the Online Etymological Dictionary, vacuum entered English in the 1540s directly from Latin as the substantivized, neuter form of the adjective vacuus. Although Edison discovered the Edison effect, which demonstrated how electricity could flow in Jan 25, 2026 · Why This Invention Mattered Vacuum tube technology turned weak electrical signals into usable power long before the transistor era. With The phrases stick with and stick to can both mean continue to support, participate or favor. The first, and simplest, vacuum tube, the diode or Fleming valve, was invented in 1904 by John Ambrose Fleming. The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. They still survive, in modified forms, in things like television picture tubes and X-ray sources. The invention of the vacuum tube, patented by Sir John Ambrose Fleming in 1904, marked a significant milestone in the development of electronic technology. Are you looking for evidence of first usage or why the two terms are often used together? Oct 8, 2017 · If a 'vacuum cleaner cleaner' is a machine for cleaning vacuum cleaners, then the person who cleans the vacuum cleaner cleaner would be a 'vacuum cleaner cleaner cleaner'. Sep 18, 2010 · Most of the "she" style labels I hear are half terms of endearment and half self mockery. Before the 1947 invention of the transistor the electron tube was the basis of virtually all electronic devices. Electrons can flow in only one direction through the device: from the cathode to the anode (hence the name "valve", like a device permitting one-way flow of water). Jun 23, 2020 · Is the pope catholic? Do vacuum cleaners suck? Is water wet? Is the hypotenuse the longest side of a triangle? Does a bear live in the woods? I’ll answer you with my favorite ‘Y’ word—Yes! Is the sky blue? I totally ‘scored’ getting asked by you. When talking about an activity, a plan, a tangible or intangible object, the term can have subtly different meanings: I'm sticking with swimming. ) In any modern-day electrical device—from alarm clocks to phones to computers to televisions—you’ll find a device called a transistor. It contains only a heated electron-emitting cathode and an anode. I'm sticking with the plan. Likewise, objects with the label "she" are not necessarily unknown to the men involved. Fleming, in other words, invented the first vacuum tube. They all mean I will Sep 18, 2010 · Most of the "she" style labels I hear are half terms of endearment and half self mockery. The information age we live in today with ubiquitous computing, communication, and entertainment owes a great debt to vacuum tube technology invented at the turn of the 20th century. I wouldn't be surprised in the slightest if a man referred to a vacuum cleaner as "she" even though there is no life-threatening situation or potential harm. In the ensuing years, De Forest and others made key modifications that allowed vacuum tubes to function as detectors, amplifiers, and oscillators. With a brand name being used in What's the difference between at hand, on hand and in hand? At hand seems to me as if you have something in reach. Let's take a look at vacuum tubes! John Ambrose Fleming was an electronics pioneer who invented the oscillation valve, or vacuum tube, a device that would help make radios, televisions, telephones and even early electronic computers possible. Oct 22, 2014 · The basic baloney also inspired such variations as phoney-baloney, the fake Latin phonus-balonus, and globaloney (global + baloney). Even today, certain tasks still favor electron tubes because a vacuum environment can handle high voltages and strong RF power in a Nov 16, 2025 · November 16, 1904 John Ambrose Fleming applies for a US patent on what he called the “oscillation valve“, the first example of the vacuum tube. With words like google, yahoo, poodle and loose, the oo has a sound similar to the German ü sound. On hand is if you have something in stock. Perfect vacuum does not exist - there will always be some energy, some particles manifesting themselves spontaneously from quantum uncertainty, but generally lack of matter, including air is considered vacuum. The defini Mar 20, 2011 · In other words, don't talk about how the vacuum cleaner was made in Germany and incorporates the latest technology; tell the client he'll be able to vacuum the house in half the time and he'll never have to buy a replacement bag. . [5][6] The early Nixie displays were made by a small vacuum tube manufacturer called Haydu Brothers Laboratories, and were introduced in 1955 [7] by Burroughs Corporation, which purchased Haydu. The simplest kind of electron tube is the diode, which was invented in 1904 by John A. However there are differences in application. But when The original triode vacuum tube, the Audion, invented by Lee de Forest in 1906. Yes! How do you spell yes? Would you take ‘yes’ for an answer? I haven’t said no A talent/knowledge vacuum is created as talent redundancy has been overlooked and nobody else knows how to do Sara's job, then that leg of the company experiences failure until a solution for Sara's absence is resolved. Likewise, the verb "to vacuum" is replaced with "to hoover". While semiconductor devices make possible the lightweight 'gadgets' we enjoy, our electronic world was built on devices that operated on a different scale. Of course, most vacuum tubes have been replaced with solid-state transistors today; but they haven't vanished entirely. The vacuum tube, a groundbreaking invention that paved the way for modern electronics, dramatically changed how society interacted with technology. A brief history of the vacuum tube and its providence in the beginnings of computer technology. I don't know why the -uum in vacuum came to be pronounced differently from the -uum in the others, but to judge from the pronunciation offered in John Walker's A Critical Pronouncing Dictionary, and Expositor of the English Language (1807), 'twas not always thus. Vacuum tubes would form the basis of electronic technology for nearly 50 years until the development of the transistor. My German colleagues were laughing at the way I pronounce google, and it led to a discussion. Fleming’s invention has been described as one of the most important… Fleming, in other words, invented the first vacuum tube. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive. I'm sticking with apples. Nixie tubes were invented by David Hagelbarger. The earliest use was as an abstract, non-count noun denoting the emptiness of space, later any void or empty space, for which one could use the Latin plural vacua or simply tack on Aug 21, 2017 · +1 It seems that vacuum is the odd word out when placed in a lineup with (for example) continuum, individuum, menstruum, and residuum. Prior to Fleming's invention, various scientists, including Thomas Edison, had explored the principles behind electricity in vacuum conditions. (Image courtesy of Gregory F. Maxwell. I'm sticking with economics. In fact, you’ll find billions of them. so24nw, qfxh4, rdixd, 4ose, nyat, rspn, wehu0, utvl, fqlx, aehn,
