dictionary for scientific and technological terms?

Question

As there are so many new words in english especially in specific aeras,so I wonder how native english speakers deal with them?Especially their pronounciation.Do you refer to a dictionary?If so,then British and American students must have a dozen of ditionaries.For examples ,a student majoring in biotechnology would have to own a dictionary on zoology ,botany,cell etc.A student in chemistry would have to own a dictionary to deal with the so many names of chemicals.And so it goes.I don't know whether my assumption is true or not ,but I really feel confused.If you do need dictionaries ,would you please recommend some to me on biology ,chemistry,medicine etc.If not ,then how do you deal with these problems.
Thanks a lot!

Answer 1

Besides Wikipedia.com there is also Wiktionary.com.

Native English speakers don't learn the pronunciation of every single word. They learn the rules of pronunciation and just learn the few exceptions. Many scientific terms, including nearly all biological classifications, are derived from Latin, which has simple and consistent rules. If you speak Italian, Spanish, or Greek, the Latin comes easy. Many non-scientific English words also come from Latin roots.

Answer 2

The McGraw-Hill Dictionary of Scientific and Technical Terms
