I know, I know, another meeting. But… it’s Goldschmidt time again!
conf.goldschmidt.info/goldschmidt/2024/goldschmidt/2024/meetingapp.cgi
The 2024 Goldschmidt conference (in Chicago) is named for Victor Goldschmidt- not just the eminent professor of geochemistry, but one of the very founders of that field. In particular, Goldschmidt’s work on meteorites (in relation to the Earth’s chemistry) is pivotal. All who speak of meteorites (well, not the basic cable channels) speak in language that comes to us through V. Goldschmidt. Our very understanding of the makeup of the new Earth from dust and gas in space, came to us through Goldschmidt. In fact, I’d say that anyone who doesn’t speak of chemistry/formation without having read (directly or indirectly) Goldschmidt’s words doesn’t speak our language.
