Nuns Discussing Drinks

Arthur was sitting outside his local pub one day, enjoying a quiet pint and generally feeling good about himself, when a nun suddenly appears at his table and starts decrying the evils of drink.
"You should be ashamed of yourself young man! Drinking is a Sin! Alcohol is the blood of the devil!"
Now Arthur gets pretty annoyed about this, and goes on the offensive.
"How do *you* know, Sister?"
"My Mother Superior told me so"
"But have you ever had a drink yourself? How can you be sure that what you are saying is right?"
"Don't be ridiculous - of course I have never taken alcohol myself"
"Then let me buy you a drink - if you still believe afterwards that it is evil I will give up drink for life"
"How could I, a Nun, sit outside this public house drinking?!"
"I'll get the barman to put it in a teacup for you, them no-one will know"
The Nun reluctantly agrees, so Arthur goes inside to the bar.
"Another pint for me, and a triple vodka on the rocks", then he lowers his voice and says to the barman "... and could you put the vodka in a teacup?"
"Oh no! It's not that drunken Nun again is it?"

Transistor

In 1947, the transistor was first demonstrated by Walter H. Brattain and John Bardeen to their higher-ups at Bell Laboratories. A microphone and headphones were connected to the transistor, and the device was actually spoken over "with no noticeable change in quality" as Brattain wrote in his notes about that day. The name transistor came from its electrical property known as trans-resistance. The original device, which the researchers first had working on 16 Dec 1947 was a point-contact version, which was later improved by William Schockley as a junction transistor. The inventors shared the 1956 Nobel prize in physics for their work. The transistor replaced the bulkier vacuum tube, and was referred to as the electronic engineer's dream.Image: the first point contact transistor.
