My DS9 was playing with a soccer ball in our garden. Then, suddenly, he stoptted and asked me if a LASER can break an atom ....

He asked me while I was driving if a car can stop intentaneously. I started answering him with the concept of mass and kinetic energy. Then I told him that to stop a car you need to convert this energy to another kind of energy. I asked him if he has an idea on what kind of energy and how is the conversion done. He answered me : in heat by friction (not saying breaking)... Well may be, it is normal, I have no idea if other kids of his age would have answered the same way.
