Selected Topics in History of Science Doing Science Internationally in the early 20th century Lecture 3 21 March 2024 Doing Science Internationally in the early 20th century Science communication  Polished pieces of thought – books and articles – periodicals  How do we know what scientists thought?  manuscripts (even fragments)  letters (if preserved)  How do we know who talked to whom?  mentioning them in letters, reports and other ephemerals  word of mouth Science done internationally?  What does it mean?  Letter Exchange  Translations  Universities as meeting places  Studying abroad  Obstacles to meeting in person:  Distance  Borders  … 1893: Columbian exhibition  Meeting of mathematicians: associated  Organised by Felix Klein  Two other participants from Europe:  Eduard Study  Norbert Herz  Compare: Antonín Dvořák (1892-1895)  Journey nine days (train, ship, train)  for a stay months, not days, long American mathematics: offspring of German and British mathematics?
