Hello everyone!

This questions seems to interest a lot of people, which is a very good thing.

Unfortunately, it has also attracted a couple of answers that were not in accordance with our rules.

I want to remind everyone that answers in this subreddit should be comprehensive, informative, and in-depth and if possible rely on sources. Just a short sentence or just a link to some other website (e.g. wikipedia) will have to be removed. The reasoning for this can be found in our rules as well as in the relevant discussion thread.

Thank you for reading and taking the time to familiarize yourself with these rules.
