According to the Fields medal winner Cédric Villani, in the Japanese language
the word ' **analysis** ' is (I quote) " _the same word_ " as the word for '
**fine cuisine** '.

Such can be seen in [a video of a recorded lecture of him entitled "The
Extraordinary Theorems of John Nash" at the Royal Institution, published on 2
November 2016, about 22 minutes and 12 seconds through the
footage](https://www.youtube.com/watch?v=iHKa8F-RsEM&t=1332).

I assume that Villani has more knowledge of mathematics than of Japanese, and
we have to bear in mind this was not the focus of the speech but one of many
trivialities to (quite successfully in my opinion) spice up the
comprehensibility and inspiration of a math lecture.

Of further interest: is the Japanese word for ' **analysis** ' at least part
of the Japanese term for ' **mathematical analysis** ', or requires the second
specific mathematical meaning an exclusive expression instead?

Who can elaborate on, clarify, validate or debunk this please? In particular,
it is not clear what is insinuated by the usage of the expression " _the same
word_ ". Which word is being concerned here please?

question
translation homophonic-kanji terminology mathematics
Is [mathematical] 'analysis' in Japanese the same word as 'fine cuisine' in Japanese?
No. Japanese "haute cuisine" is called 懐石(料理). Mathematical analysis is 解析(学).
What is true is that 懐石 and 解析 are homophones, both pronounced かいせき and, in
context, both may be referred to as かいせき. However, they are not the same word.

By the way, there are more homophones for かいせき, so he could have also said
that "analysis" is the "same word" as _bizarre stones_ (怪石) or _dissection_
(as in dissected/heavily eroded plateau) (開析) or even _meeting place_ or
_party table_ (会席).

answer
While the pronunciation is the same, the words' etymologies are unrelated.

Mathematical analysis is 解析(kaiseki かいせき) while (Japanese) fine cuisine is
懐石(kaiseki かいせき).

Both 解 and 析 roughly stands for "understanding", "taking apart". For example,
解説(kaisetu) means "To orally explain", 分析(bunseki) means "To analyze". On the
other hand, 懐(kai) refers to the pocket-like space that is created above the
belt, around the belly button and 石(seki) means stone. It originally refers to
a technique used by Buddhists, where they would pack a warm stone in that
pocket to suppress hunger.

I.e. they are not at all the same word, but they do share the pronunciation.
