I started contributing to wikipedia on exactly December 31, 2002 HARRRRRRRRRRRRRRRR. The range of my interests is probably not much different from other geeks; they include computer science, particularly programming languages, the interpretation of them and designing (not implementing) operating system concepts, pure mathematics, especially set and category theories, TV cartoons, Japanese animations and manga such as the Simpsons, the Ghost in the Shell and Love Hina. My favorite podcast is In Our Time, a discussion program. I switched from ThinkPad to iBook G3 in early 2003 and bought a new G4 iBook in March 2005. I've been an iPhone user since 2008. I'm a reader of Wikipedia:Wikipedia Signpost.

Wikistress: comfortably numb?

• Ethnicity: Japanese
• Degree: Master's degree in mathematics from Hokkaido University
• Religion: Atheism
• Computers: MacBook, iPhone 3G and iPad

To do

• http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20030503a1.htm
• Correct Referential transparency
• Start Historical Japanese name
• Rework on History of calculus (I wish). The current article (as of Nov. 07) doesn't mention many key facts; e.g., difference between derivatives, differentials, Cauchy's contribution to the rigor formulation of differential calculus.
• Eliminate duplication in Fujiwara family
• Write about finalization issue at Object lifetime using [2]
• Mention NewGlobalRef at Java Native Interface (or maybe completely rewrite it by translating corresponding articles in other languages.)
• Reorganize Optimization (computer science)
• Write School Education Law, a very important topic
• Create Lie algebra action, special linear Lie algebra, simple Lie algebra, realization of Lie algebra, Lie group–Lie algebra correspondence. Redirects are not options.
• Add proofs to Tietze extension theorem and Stone's representation theorem for Boolean algebras.
• Rewrite the community section in Wikipedia after Wikipedia made the license switch. (Don't forget to check out http://blog.citizendium.org/. He knows Wikipedia, obviously.) Mention Wikipedia:School and University projects. Don't forget about knol, which is under cc-by-sa. Also, study the structure of Encyclopedia Britannica, which can be used as a prototype.
• Write symmetric operator; (in particular, a section on symmetric extension.) (see Extensions of symmetric operators)
• Translate French versions of (thereby expand) Wedderburn's little theorem and Quadratic field.
• Expand Augustin Louis Cauchy by translating the French version.
• In Banach algebra, discuss an application to abstract harmonic analysis (via multiplier algebra?) [3]
• Lelong number (Jean-Pierre Demailly can be used as a source. That is, [4])
• Write a sketch of proof to Weyl's completely reducibility theorem.
• Open mapping theorem: http://www.math.rutgers.edu/~sussmann/papers/paper-lindquist-Festschrift-2002.pdf
• Expand Carl Gustav Jacob Jacobi.
• Add to mean value theorem its Banach version. (For the proof, try proof by contradiction.)
• Data-dump knol.
• Translate the French version of Picard–Lindelöf theorem to expand it.
• Cite a strengthened form of Hartogs extension theorem from Demailly.
• Discuss complete reducibility in diagonalizable matrix
• In unbounded operator mention von Neumann's result that shows that the algebra of symmetric operators satisfying XXX is automatically an algebra of self-adjoint operators.
• Import Neoclassical_Schools_(1871-today) from CZ.
• Add a proof to the Borel fixed-point theorem, Peano existence theorem
• Create Morse lemma (see Hormander III for a proof)

Quotes

Most potential wikipedians "wash out" in a month. The rest get "killed in action" within a year. And the majority of the rest are quite happy to take an "honorable discharge" after a few "tours of duty". This is gruelling, stressful stuff. We don't have to run through the jungle, we have to "think" through it, which is a different but equally challenging task.
