By having a conversation with it. Ask probing questions. Verify later with wikipedia. For instance I asked it about space time metrics, and I learned about the varying types and in what circumstances each are used.

Think of it like learning about things from mates at the bar. In the thick of it there may be bits of inaccuracy, but you'll certainly know more about a topic than before. Then you can verify bits of things later in papers or books, etc.
