A little girl was talking to her teacher about whales. The teacher said it was physically impossible for a whale to swallow a human because even though a whale is a very large mammal, its throat is very small. The little girl stated that Jonah was swallowed by a whale. The teacher reiterated that a whale could not swallow a human, it was impossible. The little girl said, "When I get to heaven I will ask Jonah".
The teacher asked, "What if Jonah went to hell?"
The little girl replied, "Then you ask him!"

John Walker

Born 29 May 1781; died 1 May 1859 at age 77.English chemist and inventor who invented friction matches. He made them from small wooden sticks which he coated with sulphur, then tipped with a mixture of potassium chlorate, antimony sulphide and a binder of gum arabic. After searching for a suitable mixture with the intent of making a useful way to start a fire, he was successful on 27 Nov 1826. Beginning on 7 Apr 1827, he sold them in boxes of 50 for a shilling, with a folded slip of sandpaper as a striking surface. He called them Congreves, to honour Sir William Congreve, known for his invention of military rockets. He declined to patent the matches, yet was still able to make a comfortable income from them.«
