I was out walking with my 4 ye...

I was out walking with my 4 year old daughter. She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.

"Why?" my daughter asked.

"Because it's been laying outside, you don't know where it's been, it's dirty and probably has germs" I replied.

At this point, my daughter looked at me with total admiration and asked, "Wow! How do you know all this stuff?"

"Uh," I was thinking quickly, "All moms know this stuff. It's on the Mommy Test. You have to know it, or they don't let you be a Mommy." We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information.

"OH...I get it!" she beamed, "So if you don't pass the test you have to be the daddy."

"Exactly" I replied back with a big smile on my face and joy in my heart.

Born 9 Jul 1926.American-Danish physicist, born in Chicago, Ill., who shared the 1975 Nobel Prize for Physics with Aage N. Bohr and James Rainwater for "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection." This work determined the asymmetrical shapes of certain atomic nuclei and the reasons behind such asymmetries. Later research investigated the fact that nuclear matter has properties reminiscent of superconductors.
