ぎょーむ日誌 2003-11-23

2003 年 11 月 23 日 (日)

• 0950 起床． なんかひたすら寝てるな． 朝飯． コーヒー．
• そして時間が有効活用できない． 1330 自宅発北大構内走． 今日は晴． 昨日の雪はほとんど融けてしまっている． 45 分間ほど走ってもどる． 体重 71.0kg． 昼飯．
• 1520 自宅発． 晴． 1530 研究室着．
• ぢりぢりと統計学授業の準備． あと一回で終了． 「割算すんな」 講釈の予定．

• しかしその後に日曜日の夜なのに， このようなところでくすぶってる大学院生たちの持ちこむ面倒にまきこまれる． 本日の教訓: 締め切りがせまってくると人間だれしも理不尽になる．
• 今年最後のサロベツ往復を無事に終えた M2 西村さんと， その子分 M1 たちが戻ってくる． 道北はけっこう積雪してたそーで．
• 2340 研究室発． 2400 帰宅． 晩飯．
• 2500 消灯．
• [今日の素読]
  • Salsburg, D. 2001. `` The Lady Tasting Tea -- How statistics revolutionized science in the twentieth century''. Owl Book.
  • Chapter 20. Just A Plain Texas Farm Boy
    • Statistics and abstraction
  • The theories of mathematical statistics, once thoght by mathematicians to be too mired in messy practical problems, have become clarified and honed into mathematical beauty. Abraham Wald unified the work on estimation theory by creating a highly abstract generalization known as ``decision theory,'' wherein different theoretical properties produce different criteria for estimates. R.A. Fisher's work on the design of experiments made use of theorems from finite group theory and opened up fascinating ways of looking at comparisons of different treatments. From this came a branch of mathematics called ``design of experiments,'' but the papers published in this field often deal with experiments so complicated that no parcticing scientist would ever use them.
  • The mathematics departments of American and European universities missed the boat when mathematical statistics arrived on the scene. With Wilks leading the way, many universities developed separate statistics departments. The mathematics departments missed the boat again when the digital computer arrived, disdaining it as a mere machine for doing engineering calculations. Separate computer science departments arose, some of them spun off from engineering departments, others spun off from statistics departments. The next big revolution that involved new mathematical ideas was the development of molecular biology in the 1980s. As we shall see in chapter 28, both the mathematics and the statistics departments missed that particular boat.
