Thomas Henry Moray

Thomas Henry Moray is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Thomas Henry Moray rather than just read about it. In short: Thomas Henry Moray (August 28, 1892 - May 18, 1974) was an inventor from Salt Lake City, Utah. He received US patent 2,460,707, "Electrotherapeutic Device", in February 1949, after a process of 17 years in discussions with the patent office.

Key takeaways

Thomas Henry Moray belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Thomas Henry Moray to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Thomas Henry Moray from memory before moving on to harder problems.

Reference excerpt

Thomas Henry Moray (August 28, 1892 - May 18, 1974) was an inventor from Salt Lake City, Utah. He received US patent 2,460,707, "Electrotherapeutic Device", in February 1949, after a process of 17 years in discussions with the patent office. During the 1920s, Moray worked in the emerging field of radio. After hundreds of experiments designed to improve radio reception, Moray claimed to have discovered a source of energy transmission apparently available everywhere. Using advanced ideas in solid state detectors, he developed a power source which he claimed to produce 50,000 watts. By the early 1930s, dozens of people had reportedly witnessed demonstrations of this technology. In 1944 Moray was paid $25 a day by the rural electrification administration to perfect his system of drawing electrical energy out of the atmosphere. He claimed his invention produced electricity with no exterior input of energy. The primary component of the device was a non-heated vacuum tube. At the time most vacuum tubes had heaters built inside. The patent office refused to grant his patent, initially, because they claimed that any vacuum tube without a heater would not work. He was never granted a patent for his power supply device. He did have other inventions and was able to obtain a patent for one of those, the Electrotherapeutic device.

Worked examples

Example 1 — a first encounter with Thomas Henry Moray

Start with the simplest possible case. Write down what Thomas Henry Moray claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thomas Henry Moray before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thomas Henry Moray ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thomas Henry Moray

In research: Thomas Henry Moray appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Thomas Henry Moray in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Thomas Henry Moray is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1892 births, 1974 deaths, 20th-century American inventors, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas Henry Moray outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
