While teaching a class on atomic structure I explained that everything is made of atoms. One of the students asked, “Where do atoms come from?”
I said, “They are just here.”
He then asked, “How are they made?”
“They are not made, they just change form.”
“Then how do things grow more atoms?”
“Atoms are just transfered from one place to another and added to growing things.” I replied.
He still had a puzzled look on his face.

I have continued to think about the concept that we are a bunch of atoms that were some where else and now they make up a body and mind. Everyday we are adding and shedding atoms. When we die the atoms that make up this body (I began to write our atoms and our body, but who really owns the atoms?) will join up with other atoms to make something else. Is this reincarnation?

This particular configuration of atoms will only last a blink of an eye in the history of the universe. The atoms that have come together in this particular form have been around since the beginning of the universe and will be around until the end of the universe.

So why do we think we have any control over anything? There is nothing wrong here.

Do you remember one of the physical constants you learned in school? Light travels at a constant speed and can not be changed -186,000 m/sec. Well now we have to teach students that is not true. Lene Hau of Harvard has been able to stop light, move an imprint of it, and start it again.

Listen to Dr. Hau on NPR here or go the web site for her lab to see a demonstration here.
