1850年至1950年及以後的科學/數學主要語言是什麼


2

19世紀下半葉和20世紀上半葉是現代數學和科學的黃金時代,因為在此期間提出並發展了許多重要的思想和理論。我認為德語和法語是該時期發表的數學論文的主要語言。在第二次世界大戰之後,眾所周知,直到現在,英語已逐漸成為數學論文的主要語言。

我希望獲得更多統計數據,例如在1850年至1950年及以後的主要期刊上以德語/法語/英語/其他發表的文章。謝謝。

Here are plots using Jahrbuch for 1870–1940 and Zentralblatt after that. A glance at their detailed output suggests some unreliability (e.g. Zentralblatt counts a paper twice when both reviewed it), but hopefully not too much overall. Papers and books in other languages (Danish, Dutch, Hungarian, Japanese, Latin, Norwegian, Polish, Portuguese, Spanish, Swedish,...) are left out as only after 1980 does their sum total (slightly) surpass Italian.

1870-2009
