A husband died. A few weeks later the wife died. As she got to heaven she saw her husband. She ran up to him with tears in her eyes.
'Darling, how I've missed you!'
The husband extends his arms stopping her from embracing him and says, 'Whoa there woman, the contract was until death!'
Edison phonographIn 1877, Thomas Edison demonstrated his hand-cranked phonograph that recorded sound onto tinfoil cylinders. Although 12 Aug 1877, is often given as the date of this invention, it may have been only at the stage of a sketch, since Edison did not file for the patent until 24 Dec 1877. The idea came to Edison while working on a telegraph transmitter, when he noted that when the the tape of the machine was played at high speed, it gave off a noise resembling spoken words. After experimenting with a needle attached to the diaphragm of a telephone receiver to prick paper tape to record a message, his idea evolved to using a stylus on a tinfoil cylinder.«* |
