A pious man who had reached th...

A pious man who had reached the age of 105 suddenly stopped going to synagogue. Alarmed by the old fellow's absence after so many years of faithful attendance the Rabbi went to see him.
He found him in excellent health, so the Rabbi asked, "How come after all these years we don't see you at services anymore?"
The old man looked around and lowered his voice. "I'll tell you, Rabbi," he whispered. "When I got to be 90, I expected God to take me any day. But then I got to be 95, then 100, then 105. So I figured that God is very busy and must've forgotten about me, and I don't want to remind Him!"

Arago announces electromagnetism

In 1820, Francois Arago announced that a copper wire between the poles of a voltaic cell, could laterally attract iron filings to itself (Ann. de Chim. et de Physique., xv. p.93). His discovery came in the same year that Oersted discovered that an electric current flowing in a wire would deflect a neighbouring compass needle. Arago in the same publication described how he had successfully succeeded in causing permanent magnetism in steel needles laid at right angles to the copper wire. Arago and André-Marie Ampère, discussed and experimented with forming the copper wire into a helix to intensify the magnetizing action. However, it was not until 1825 that the electromagnet in its familiar form was invented by William Sturgeon.«
