Hitoshi Murayama

Hitoshi Murayama 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 Hitoshi Murayama rather than just read about it. In short: Hitoshi Murayama (村山斉, Murayama Hitoshi; 21 March 1964 -) is a Japanese-born physicist with notable contributions in the fields of particle physics and cosmology. He is currently a professor at the Center for Theoretical Physics at the University of California, Berkeley, and was the Director of the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo.

Key takeaways

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

Reference excerpt

Hitoshi Murayama (村山斉, Murayama Hitoshi; 21 March 1964 -) is a Japanese-born physicist with notable contributions in the fields of particle physics and cosmology. He is currently a professor at the Center for Theoretical Physics at the University of California, Berkeley, and was the Director of the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo.

Biography Born in Japan in 1964, Murayama obtained his B.Sc. in Physics from the University of Tokyo in 1986. He completed his Ph.D. in Tokyo in 1991. In 1993, he moved to the US to join the Lawrence Berkeley National Laboratory as a post-doctoral research fellow. In 1995, he was appointed as an associate professor in University of California, Berkeley, where he became a full professor of physics in 2000. He is the founding director of the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) at the University of Tokyo since 2007. In addition, he has been a visiting scientist at CERN since 2016. In 2013, he was elected to the American Academy of Arts and Sciences and was chosen as a fellow of the American Physical Society. In October 2014, he delivered an invited lecture titled "Science for Peace and Development" at the Headquarters of the United Nations in an event honoring the 60th anniversary of CERN.

Scientific Work Professor Murayama is involved in the KamLAND neutrino experiment at the Kamioka Observatory, an underground neutrino detection facility near Toyama, Japan. The KamLAND collaboration won the Breakthrough Prize in Fundamental Physics in 2016. In 1998, Murayama, Gian Giudice, Markus Luty and Riccardo Rattazzi discovered "anomaly mediated supersymmetry breaking, a subtle quantum mechanical mechanism which contributes to the gaugino masses in supergravity".

Worked examples

Example 1 — a first encounter with Hitoshi Murayama

Start with the simplest possible case. Write down what Hitoshi Murayama 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 Hitoshi Murayama 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 Hitoshi Murayama 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 Hitoshi Murayama

In research: Hitoshi Murayama 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 Hitoshi Murayama 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: Hitoshi Murayama is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 births, Academic staff of the University of Tokyo, Fellows of the American Academy of Arts and Sciences, so understanding it makes those chapters shorter.
In everyday life: Look for Hitoshi Murayama 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.
