It's really a little late for me to make this science page. The right diagram was originally showed on the door of a Stanford mathematics professor's office. The picture is ridiculous but if you don't know mathematics, you won't know what's wrong.
Science is fantastic.
Although I disagree with this crazy point, knowing more of unknowns is always the goal of science. Some of them have not been solved yet. Ruler Problem Rulers with few labels for reading many integer lengths. Some combination problems. Some integer problems.
