Reference excerpt

Mitsutaka Fujita (藤田光孝, Fujita Mitsutaka; August 16, 1959 – March 18, 1998) was a Japanese physicist. He proposed the edge state that is unique to graphene zigzag edges. Also, he theoretically pointed out the importance and peculiarity of nanoscale and edge shape effects in nanographene. The theoretical concept of graphene nanoribbons was introduced by him and his research group to study the nanoscale effect of graphene. He was an associate professor at Tsukuba University, and died of a subarachnoid hemorrhage on March 18, 1998. His posthumous name is Rikakuin-Shinju-Houkou-Koji (理覚院深珠放光居士) in Japanese.

Awards After his death, the original paper on graphene edge state and graphene nanoribbons was awarded the JPS Best Paper Award in March 2003 from the Physical Society of Japan.

Worked examples

Example 1 — a first encounter with Mitsutaka Fujita

Start with the simplest possible case. Write down what Mitsutaka Fujita 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 Mitsutaka Fujita 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 Mitsutaka Fujita 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 Mitsutaka Fujita

In research: Mitsutaka Fujita 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 Mitsutaka Fujita 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: Mitsutaka Fujita is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, 1998 deaths, Academic staff of the University of Tsukuba, so understanding it makes those chapters shorter.
In everyday life: Look for Mitsutaka Fujita 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.
