…First, mineralogist CS Weiss focused on the anisotropy of crystals and studied crystal morphology using the concepts of crystal zones and crystal axes, but he did not consider the use of oblique axes, which left confusion in the interpretation of some phenomena. Soon, mineralogist F. Mohs pointed out that there are cases where oblique axes are necessary, and his student CF Naumann established the necessity. In 1830, mineralogist JFC Hessel succeeded in deriving 32 types of crystallographic point groups, but this important discovery remained unknown to the world for the next 60 years. … *Some of the terminology that mentions "Naumann, CF" is listed below.

…まず鉱物学者ワイスC.S.Weissは結晶の異方性に注目し,晶帯および結晶軸の概念を用いて結晶形態の研究を行ったが,斜交軸をとることに考え及ばなかったために,一部の現象の解釈に混乱が残った。斜交軸をとる必要がある場合もあることは,間もなく鉱物学者モースF.Mohsが指摘し,彼の弟子ナウマンC.F.Naumannがその必要性を確立した。1830年に鉱物学者ヘッセルJ.F.C.Hesselが32種の結晶学的点群の導出に成功したが,この重要な発見はその後60年もの長い間世に知られないままであった。… ※「Naumann,C.F.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
