Imagine a new model is derived for a physical phenomenon and consider the following sentence:
A new formulation is derived for the phenomenon of X.
Is there any formal or technical word for "new"?
To me new seems to work best because its saying a new formulation (forming) is derived (obtained) for the phenomenon (existance) of X. so if they create something to obtain the existance it implize that it's new and purposly made for X. So if this wasn't new why would they create it to obtain it why don't they just buy it
I've been reading a lot of academic papers recently so the answer is that the word late is closest in meaning to the word new
Late research has shown that... And so on
However current and contemporary are used when the word late doesn't work in a certain context. But I assume that's not what you're looking for.
I don't really see anything informal using new either
One alternative I've seen in many academic papers is "novel".
