Clever ideas for describing myself?

Are you sure you mean "scientific" and not "rarer/more cultural" words?

Also I think you mean describing your personality (you don't give too much info in your question and I can see that English isn't your first language) if so try saying :

I have an ambient-type of nature. I adapt easily to environments, giving thought before action and fitting in if needed with ease. Depending on the place and actions given at that time I might be caring or offensive as the situation dictates, I'm somewhat driven by the moment's expectations (street talk it would sound like this : man i'm chill but he pisses me off, then **** that- it's all about how you say it), of course as mentioned before the state of one's feelings and way of being differ as the present requires it. ( I'm not sure if you realize it but as smart as what you read sounded it's the same thing said 3 times over with different words, these are the things you should know, people are amazed by smart talk, you can tell them a sentence 10 times with other words then used previously and they will still be intrigued)

If that doesn't fit you then no problem:

Usually a mild-type of person (mild=calm/chill but using a fancier word) when with friends or acquaintances. Talkative if the situation requires it like during a gathering with friends or in a meeting with known people (see how I didn't use "acquaintances" again?! It's so it feels different and non-repetitive as well as something new that I haven't said before even though it's the exact same thing). I always like to be around people and them around me, the need to be in the center of attention is somewhat strange to me since I'm not a fan of it, only imagine all the people waiting for you to say something do something or entertain them. It's too difficult of a work for me.(What I just said sums up in "I'm relaxed and don't wanna be the center of attention, it's too much work-but instead of using simple words I dragged it on like it was tied to a speeding car, also don't use often heard phrases like :too much/ use "too difficult of a work" wow that sounds so much smarter and it's longer).

Hope that's what you are looking for.
