Correct me if I am wrong:

How about chemical formulas

The eternal battle of good versus evil

medical disease that needs cured, like cancer

The lineup of musical notes in a melody, if you change a note you change the melody

DNA

Sounds and syllables that make up a particular language

The reason for a the shape of a bird's beak. How does that affect it's diet?

Arranging pixels to make a picture.

writing code to build a computer program

If I am right about any of these, how does that affect the way history sees Benjamin Franklin?
