The groundbreaking «Russian-Crimean Tatar Dictionary of Special Lexicon for Chemistry and Associated Fields of Knowledge» by Candidate of Chemical Sciences Vadim Mireyev has been published. This unique work aims to modernize and systematize Crimean Tatar chemical terminology, which has remained largely unchanged since the 1930s. The dictionary, based on modern linguistic means and reintroducing forgotten pre-war terms into scientific circulation, will become an indispensable tool for translators, authors of scientific works, as well as future students and teachers in chemical specialties. The book can be purchased from the author and at the «Hazine» bookstore.
