Scientist = 科学家 + 科学工作者

Call me a scientist, a.k.a. genius.
Cool to be a scientific worker!

Lots of Chinese words ending with 家 mean XX master/genius. So Einstein is a 科学家, but some guy working in NASA is only a 科学工作者, while both are scientists in English.

And 家 is a compliment, so you can't literally say "I'm a 科学家" in Chinese even if you're a world-famous genius. Otherwise, you'd sound arrogant or rude. You've got to be careful with this hierarchy in Chinese.

Here's some examples:

scientist
科学家／科学工作者

artist
艺术家／艺术工作者

writer
作家／作者

politician
政治家／领导干部 or 从政的人

revolutionary
革命家／革命分子 or 革命者
