Takeshi Nagata (永田 武, Nagata Takeshi; June 24, 1913 – June 3, 1991) was a Japanese geophysicist. He studied geomagnetism. He won the Gold Medal of the Royal Astronomical Society in 1987. Mount Nagata in Antarctica is named after him.

Takeshi Nagata
Takeshi Nagata is a astronomy 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 Takeshi Nagata rather than just read about it. In short: Takeshi Nagata (永田 武, Nagata Takeshi; June 24, 1913 – June 3, 1991) was a Japanese geophysicist. He studied geomagnetism.
Key takeaways
- Takeshi Nagata belongs to astronomy; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Takeshi Nagata to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Takeshi Nagata from memory before moving on to harder problems.
Reference excerpt
Worked examples
Example 1 — a first encounter with Takeshi Nagata
Start with the simplest possible case. Write down what Takeshi Nagata claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Takeshi Nagata 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 Takeshi Nagata 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 Takeshi Nagata
- In research
- Takeshi Nagata appears in astronomy 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 Takeshi Nagata 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
- Takeshi Nagata is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1991 deaths, 20th-century Japanese astronomers, so understanding it makes those chapters shorter.
- In everyday life
- Look for Takeshi Nagata 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.
