One way to look at it is that most college textbooks are bad. They are written by one person, who has limited time, and limited understanding. And then you have a teacher who knows even less than the textbook, trying to explain the textbook.
In contrast, Wikipedia editors have all the time they care to spend on the subject (which is a lot!). They often reproduce the original discoverer's words, when appropriate. E.g., https://en.wikipedia.org/wiki/Central_dogma_of_molecular_bio... uses Crick's words. Whereas in the case of Maxwell, the formulation "is credited to Oliver Heaviside". Long story short: Wikipedia has the best explanations, and if you don't think so then fix it!
