In addition to chemical elements, I also “collect” foreign languages. I speak ten of them, most of which I taught myself. These languages range from English, French, Spanish, Portuguese, Italian, Danish, Dutch, Serbian, and Romanian (I should brush up on the last two) to Norwegian, Swedish, and Afrikaans, which I know how to read. I’m currently combining my passion for chemistry and languages by writing a handbook for industrial chemists. The book is about all of the elements and will be more than 1,000 pages long. It is scheduled to appear next year.
