Ask with a question mark.
Type ? and a question in the address bar and Apogee builds a board: a straight answer, facts with their sources, diagrams and small simulations you can play with. Follow-ups land on the same board, and ⇧↩ turns any search into one.
- The answer in about a second, the full board in five to eight
- Real photos from Wikimedia Commons, never generated ones
- Boards disappear when you close them
