Dog playing piano

It is World Piano Day!

A man walks into a bar with a small dog under his arm and sits down at the counter, placing the dog on the stool next to him. The bartender says, "Sorry, pal. No dogs allowed."
The man says, "But this is a special dog – he plays the piano!"
The bartender replies, "Well, if he can play that piano, you both can stay... and have a drink on the house!"
So the man puts the dog on the piano stool, and the dog starts playing. Ragtime, Mozart... and then he plays some rock 'n' roll. The bartender and patrons are amazed.
Suddenly, a bigger dog runs in, grabs the small dog by the scruff of the neck, and drags him out. The bartender asks the man, "What was that all about?"
The man replies, "Oh, that was his mother. She wanted him to be a doctor."

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.
