But not only is that not the case, we don't expect that to be the case for most topics. Most people expect to go to Wikipedia, type in Caligula, and get an article about Gaius Julius Caesar Augustus Germanicus that was titled "Caligula" and which mentions that he is commonly known as Caligula in the first paragraph.

If the people who edited the history subsections had the same attitude as the people who edited many of the math and science pages, there would be only an article titled "Gaius Julius Caesar Augustus Germanicus", which wouldn't use the name "Caligula" anywhere, but somewhere deep within the article would mention that he had the nickname of "little soldier's boot." Because, hey, you need to have the knowledge of the parent topic, and if you don't even know the guys name then why are you even looking up the article?

I'm sure the math and science people would go nuts if the articles for other topics were written in a similarly opaque fashion. But they seem to mistake the clarity others write with as evidence that those topics are inherently simpler.
