• 1350 自宅発北大構内走． いいぐあいの曇天． 1445 帰宅． 脚冷却． シャワー． 体重 71.2kg． 昼飯．
• 洗濯とかアイロンがけとか． 1630 自宅発． 曇． 1640 研究室着．
• また ぱいぷ樹木 にせ地下部づくりの続き． 三次元図をつくったりする都合上， にせ地下支配 FakeEarth の出力にまた手を加える …… っていうかっ， ostream& operator<<(ostream&, FakeEarth&) というような演算子オーヴァーロードはガマンできるとして， こいつが腐り腐れた friend 関数にしかなりえんってのがへっぽこ度 128% にまで強まった へっぽこすとりーむの正真正銘へっぽこぴー正体そのものだっ!! …… とキレたりしながら書き直すわけですよ． すかっと書けないので楽しくない． しかし <iostream> 使わざるをえない． ええ，ええ <cstdio> の sprintf つかいやす． だれが setf(ios::scientific) だの precision(3) などという気色わるいもん使うか．
• ぱいぷ樹木用 POV-Ray コード生成 Perl スクリプトに手をいれる． FakeEarth 試験運転プログラムはかなり直す．
• というところで本日はここまで， かな． 明日から別の仕事， ちょい面倒な統計モデリングやらんといかん． あ， それから水曜日は苫小牧まで行かねば．

[にせ地下ばとる開始 (予告編)]

このまま つぎの週末ぐらいまで両雄ニラみあったままでせう． 試験運転なんでにせ地下部のみ． 地上部なくても「エサ」だけやってれば育つ． てゆーか， 地上部ができることは 「自分が所有するにせ地下部の位置を決めて名前を教えてもらう」 「てきとーな量のエサをやる」 「水をもらう」． これだけ．

• 2100 研究室発． 2110 帰宅． 晩飯．
• [今日の素読]
  • Salsburg, D. 2001. `` The Lady Tasting Tea -- How statistics revolutionized science in the twentieth century''. Owl Book.
  • Chapter 4. Raking over the muck heap
    • Fisher versus Karl Pearson
    • Fisher the ``Fascist''
    • Statistical methods for research workers
    • Rothamsted and agricultural experiments
  • Despite, or perhaps because of, its lack of theoretical mathematics, the book was rapidly taken up by the scientific community. It met a serious need. It could be handed to a lab technician with minimum mathematical training, and that technician could use it. The scientists who used it took Fisher's assertions as correct. The mathematicans who reviewed it looked askance at its audacious unproven statements, and many wondered how he had come to these conclusions.
  • But all of this was still in the future in 1919, when Fisher abandoned his unsuccessful career as a schoolmaster. He had just finished a monumental work, combining Galton's correlation coefficient and the gene theory of Mendelian heredity. The paper had been rejected by the Royal Society and by Pearson at Biometrika. Fisher heard that the Royal Society of Edinburgh was looking for papers to publish in its Transactions, but that the authors were expected to pay for the publication costs. Thus, he paid to have his next mathematical work published in an obscure journal.
  • At this point, Karl Pearson, still impressed by young Fisher, came through with an offer to take him on as chief statistician at the Galton Biometrical Laboratory. The correspondence between the two men was cordial, but it was obvious to Fisher that Peason was strong-willed and dominating. His chief statistician would, at best, be engaged in detailed calculations that were dictated by Pearson.
  • Sir John looked at this vast collection of data and decided that maybe somebody might be hired to see what was in it, take a sort of statistical look at these records. He inquired around, and someone recommended Ronald Aylmer Fisher. He offered Fisher a year's employment at a thousand pounds; he could not offer more and could not guarantee that the job would last past that one year.
  • Fisher accepted Russell's offer. He took his wife, sister-in-law, and three children into the rural area north of London. They rented a farm next door to the experimental station, where his wife and sister-in-law tended a vegetable garden and kept house for him. He put on his boots and walked across the fields to Rothamsted Agricultural Experimental Station and its ninety years of data, to engage in what he was later to call ``raking over the muck heap.''
