Atomic nucleus recoil

In 1904, a letter in the journal Nature*, Harriet Brooks pointed out a peculiar type of volatility shown by an active deposit of radium immediately after its removal from the emanation. Hahn and Russ and Markower later showed (1909) that “the effect was due to the recoil of radium B from the active surface accompanying the expulsion of an alpha-particle from Radium A. This method of the separation of the elements by recoils ultimately proved of much importance in disentangling the complicated series of changes in the radioactive bodies,”according to Ernest Rutherford (1933). Thus, Harriet Brooks was probably the first person to observe the recoil of the atomic nucleus as nuclear particles were emitted during radioactive decay.(*vol. 70, p. 270)

Nice pigs sir

A Secret Service agent is standing at the bottom of the stairs as President Clinton is leaving Air Force One, and can't help but notice that the President has a pig under each arm.

The Agent salutes and says, "Welcome back, Mr. President. Nice pigs, sir."

Clinton smiles and says, "These aren't pigs. These are genuine Arkansas Razorbacks. I got this one for Hillary, and I got this one for Chelsea."

The Agent says, "Good trade, sir."
