The word “things” should be replaced by something more specific in order to make the sentence more precise. You should avoid general words and imprecise vocabulary. You can also consider being more specific with the phrase “scientific subjects” (which ones are you referring to?). Thus, the sentence will be more precise and more interesting to read. It is worth mentioning that this type of “vague” words are not academic since they do not follow the precise register of an academic writing and can consequently generate obstacles and misunderstandings.
