This raises the question of what level of knowledge should be assumed in Wikipedia articles Should we assume that readers are completely ignorant and write The Sun is the bright light in the sky or should we assume that they know a lot so we should discuss nuclear physics and the like  I used to work as a highschool math and science teacher so I tend to write in a way that would be appropriate for readers aged about  to  This does seem to be about right for most readers of Wikipedia Of course many readers are older but still want to learn things that highschool students learn and there must be some precocious infants wise beyond their years  So this would be my advice Dont try to impart knowledge that would already be known by an average yearold and dont write anything that would be incomprehensible to an average yearold  Does that sound reasonable
