Candidate of Science

[Piak]

Dear teacher,

What does the phrase “Professor. Candidate of Science” mean? What is the meaning of Candidate of Science?

Thank you.
Kind regards,
Piak

It's similar to a PhD:
A note about Russian higher degrees. There are two levels: 'Candidate of Science' (roughly equivalent to a Ph.D) and 'Doctor of Science' (a higher degree, entitling the person to the Full Professor's position). All those listed below will be defended in the Institute of the History of Science and Technology's Scientific Council on the History of Geography and Geology
Doctorates in progress in the history of cartography

Your reply is so great, Tdol. It is very kind of you. I can not find this phrase in any dictionaries, such as Oxford, Langman, Cambridge, Cobuild, The Newbury House Dictionaries. Not all, not available in those dictionaries!

It is my new knowledge indeed.

Thank you.

Kind regards
Piak
