Mar '26 Notes
2026年3月の個人的な学習ノート。主に代数的グラフ理論（Godsil & Royle、Biggsの教科書）の研究に焦点を当て、群論（置換、群準同型、群作用など）とグラフ理論の概念を探求。また、独立した個人ウェブサイトの「スモールウェブ」から興味深いサイトを推薦する分散型ウェブコンソール「Wander Console」の開発についても言及。

A Science paper and several other publications have incorrectly cited the compound Cr2Gr2Te6, which does not exist. The correct compound is Cr2Ge2Te6 (chromium germanium telluride), with Ge representing germanium. This typographical error has been copied across multiple scientific papers and a book chapter.
Evelyn Wood Reading Dynamics, launched in the 1950s, popularized speed reading despite scientific evidence questioning its claims of high-speed reading with full comprehension. The movement gained credibility through presidential endorsements but research shows it's essentially skimming with poor retention.
Dry ice (solid carbon dioxide) was commercialized in 1925 and became important for refrigerated transportation, reducing shipping costs by 50%. Northeastern New Mexico's Bueyeros field became a major source of pure CO2 for dry ice production. Today, much of the extracted CO2 is used for enhanced oil recovery, creating complex climate implications.
