This morning my eight years old daughter asked me: "why is it so difficult to balance on my bicycle when it is not moving?". It was very embarrassing moment, I simply could not give her a convincing answer.Then I thought of other things which "I" can not explain without using mathematics. So I decided to ask you people for help.
As well as "wy daughter's bicycle" there is the "spinning top", the issue here "I believe" is how to explain the relation between stability & motion without math?
The other "more difficult" subject, I thought about, is explaining global & local gauge principles for people with no knowledge of group theory.
So if you ,like me, can not explain the above, can you list other similar subjects?
thanks
