Katsuhiko Ishibashi

Katsuhiko Ishibashi 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 Katsuhiko Ishibashi rather than just read about it. In short: Katsuhiko Ishibashi (石橋克彦, Ishibashi Katsuhiko; born August 8, 1944) is a professor in the Research Center for Urban Safety and Security in the Graduate School of Science at Kobe University, Japan and a seismologist who has written extensively in the areas of seismicity and seismotectonics in and around the Japanese Islands. He also coined the term genpatsu-shinsai (原発震災), from the Japanese words for "nuclear power…

Key takeaways

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

Reference excerpt

Katsuhiko Ishibashi (石橋克彦, Ishibashi Katsuhiko; born August 8, 1944) is a professor in the Research Center for Urban Safety and Security in the Graduate School of Science at Kobe University, Japan and a seismologist who has written extensively in the areas of seismicity and seismotectonics in and around the Japanese Islands. He also coined the term genpatsu-shinsai (原発震災), from the Japanese words for "nuclear power" and "quake disaster". Katsuhiko Ishibashi has said that Japan's history of nuclear accidents stems from an overconfidence in plant engineering. He was a member of a 2006 Japanese government subcommittee charged with revising the national guidelines on the earthquake-resistance of nuclear power plants, published in 2007. His proposal that the committee should review the standards for surveying active faults was rejected and, at the committee's final meeting he resigned claiming that the review process was "unscientific" and the outcome rigged to suit the interests of the Japan Electric Association, which had 11 of its committee members on the 19-member government subcommittee and that among other problems the guide was "seriously flawed" as a consequence because it underestimated the design basis earthquake ground motion. In May 2011, he said: "If Japan had faced up to the dangers earlier, we could have prevented Fukushima".

Worked examples

Example 1 — a first encounter with Katsuhiko Ishibashi

Start with the simplest possible case. Write down what Katsuhiko Ishibashi 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 Katsuhiko Ishibashi 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 Katsuhiko Ishibashi 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 Katsuhiko Ishibashi

In research: Katsuhiko Ishibashi 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 Katsuhiko Ishibashi 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: Katsuhiko Ishibashi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, Academic staff of Kobe University, Japanese seismologists, so understanding it makes those chapters shorter.
In everyday life: Look for Katsuhiko Ishibashi 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.
