Being charitable, "more scientific" means more rigorous, reproducible, reliable based on the consensus of that scientific community (if any consensus exists, which it usually does in math and hard sciences), transparent in methodology, and candid about authorities cited and limitations to the experimental approach. Science is not a style guide; the purpose of a research publication is to impart a result to experts in the field and make claims that can be rigorously scrutinized. The best way to make a claim credibly is to demonstrate full fluency with the tools and techniques of the academic community in applying them thoughtfully to the chosen problem. But the result of doing that often looks downright impenetrable to the general public; see, e.g., Niven 1947 (1-page proof that pi is irrational). It's not the point of science to make it accessible to everyone. The point is to convince experts in the field of the correctness of the claim. The audiences are often totally different, and the tone and qualities of the writings likewise must vary.
replyYou might prefer that, but journal editors might not.
replyI've never had any trouble publishing in a more conversational style and have read plenty of papers that do the same. Of course, this varies by field and venue and format (journal vs. conference) and even reviewer and it's difficult to understand what the true constraints are and what the state of the publishing system is in this regard.
replyBut I suspect that a lot of academic's feelings about it are informed by what others have told them and how they've been trained, rather than by what's actually permissible in the publishing system.
