A man went to his lawyer and told him, "My neighbor owes me $500 and he doesn't want to pay up. What should I do?"
"Do you have any proof?" asked the lawyer.
"Nope," replied the man.
"Okay, then write him a letter asking him for the $1000 he owed you," said the lawyer.
"But it's only $500," replied the man.
"Precisely. That's what he will reply and we will have the proof we need to nail him."

Helium ions from radium

In 1903, the journal Nature reported that helium gas is produced by the radioactive decay of the radium. This key discovery by William Ramsay and Frederick Soddy helped to reveal the structure of atoms. In 1908, Ernest Rutherford confirmed that alpha rays and these radium emanations were one and the same: the nuclei of helium atoms, bearing a positive electrical charge. Each were future Nobel laureates in Chemistry. Ramsey won the Nobel Prize in 1904 for his discovery of the noble gases. Rutherford was recognized in 1908 for his investigations into the disintegration of the elements. Soddy was honoured in 1921 for his pioneering contributions to understanding the chemical properties of radioactive elements such as radium and uranium.[Ref: Ramsay, W. & Soddy, F. Experiments in radio-activity, and the production of helium from radium. Nature, 68, 354 - 355, (1903)]
