Could you stop your mindless dictatorial attitude? The title says "work on Newton's Principia", which suggests at least minor original contributions to the work itself.
Who do you think you are to rudely lecture people who may be more qualified than yourself?
I changed the title after that comment was posted—first to "translation of", and then to "work on" because https://news.ycombinator.com/item?id=22199282 argued—apparently reasonably—that she made contributions beyond translation. "Working on X" is standard English for a scholar studying something. It doesn't imply that they're adding to X itself. Harold Bloom worked on Shakespeare, but not even he would say that he contributed to Shakespeare's plays.
I'm sorry to come across as rude, mindless, and dictatorial. That's definitely not the intention. The intention is to prevent HN threads from getting stuck in local flamewar states that tend to burn like garbage fires and give off fumes rather than information. That's a big problem on a site like this—in fact it's the biggest problem on a site like this. It doesn't, alas, mean that we make every call correctly. If you read lopmotr's GP comment in isolation and without the flamewar problem in mind, it is probably fine.

You are the one who is constantly rude here.
