TED - What’s the difference between a scientific law and theory?

Chat with a friend about an established scientific theory, and she might reply, “Well, that’s just a theory.” But a conversation about an established scientific law rarely ends with “Well, that’s just a law.” Why is that? What is the difference between a theory and a law... and is one “better”? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

TED-Ed Original lessons feature the words and ideas of educators brought to life by professional animators.
