One day on the way home from work, I stopped at the local Pharmacy and while I was checking out, I picked up some candy to take home for me and my 7-year old son. It was a bag of Gold Coins (Gold Foil-covered chocolate candy coins).
There were many sizes, from dime to dollar. I took the bag home, and me and my son opened the bag and ate all of the coins, my son taking the bigger dollar-sized ones and me taking the smaller ones.
The next day, my wife, my son and I stopped at the Pharmacy again to pick up a few things. While my wife and I were shopping, we noticed that my son had picked up a Gold Coin Condom. Before we could catch him, he took it up to the counter and asked the Pharmacist, "What's this?"
The woman, looking very serious, said, "That's a condom, son."
To which my son replied, "My daddy BOUGHT me some of these yesterday!"
With a disgusted look on her face, the Pharmacist replied, "Those are NOT for children, young man."
And finally, my son replied, "Then I'll buy this one for my Daddy. He likes the LITTLE ones!"

Discovery of hafnium announcedIn 1922, the discovery of hafnium by Dirk Coster and Georg von Hevesy was announced by Neils Bohr as he concluded his Nobel Prize lecture, 'On The Structure of Atoms.'. Bohr received the news by telephone from Coster, just a few minutes before he began his lecture, that the β1 and β2 lines of hafnium had been identified on a photographic plate. (Bohr had suggested to them that looking at an ore of zirconium, a homologue, could be a good place to find the new element.) The discovery of hafnuium was shortly afterwards published in the 20 Jan 1923 issue of the journal Nature. Bohr and Hevesy had liked the name danium (after Denmark) for the new element, but the name hafnium (after the Roman name for Copenhagen) suggested by Coster prevailed at the time of publication.« |
