Joke Of The Day
Toilet Seat
A man decides to take the opportunity while his wife is away to paint the wooden toilet seat.
The wife comes home sooner than expected, sits, and gets the seat stuck to her rear. She is understandably distraught about this and asks her husband to drive her to the doctor.
She puts on a large overcoat so as to cover the stuck seat, and they go.
When they get to the doctor's, the man lifts his wife's coat to show their predicament. The man asks, "Doctor, have you ever seen anything like this before?"
"Well, yes," the doctor replies, "but never framed."
On This Day
Crystal rectifierIn 1874, a paper by Ferdinand Braun (1850-1918) was published in the Annalen der Physik und Chemie describing his discovery of the electrical rectifier effect. He observed that certain crystals of metal sulphides have a larger or smaller resistance to an electric current, depending on its direction of flow. He used a galena crystal, a semiconductor material composed of lead sulfide. He found the rectifying effect especially true if at least one of the electrodes was a pointed wire. Thus, he had discovered the point-contact rectifier effect, the first semiconductor device. This effect wasn't used until over 30 years later in the form of the “cat's whisker”crystal radio detector which ultimately led to the point-contact transistor first produced in 1948. |
