Wicipedia

We can't just assume that wicipaedia, or any other, you know, sight really covers the full gamet in terms of scientific terms in major languages. And even terms as simple as i wouldn't necessarily be able to go on with capedian. Even if there's a good wicipedia page, which is very detailed, it might be beyond the the level of information that you can understand,. especially if didnt take a science in a high school.
