The Monastery on a Cliff

There is a story about a monastery perched high on a cliff several hundred feet in the air. The only way to reach the monastery was to be suspended in a basket which was pulled to the top by several monks who pulled and tugged with all their strength. Obviously the ride up the steep cliff in that basket was terrifying. One tourist got exceedingly nervous about half-way up as he noticed that the rope by which he was suspended was old and frayed. With trembling voice, he asked the monk who was riding with him in the basket how often they changed the rope.
The monk thought for a moment and answered brusquely, "Whenever it breaks."

Francis William Aston

Died 20 Nov 1945 at age 68 (born 1 Sep 1877). English chemist, physicist and chemist who was awarded the 1922 Nobel Prize for Chemistry for his development of the mass spectrograph, a device that separates atoms or molecular fragments of different mass and measures those masses with remarkable accuracy. In 1910 he became an assistant to Sir J.J. Thomson at Cambridge, who was investigating positively charged rays emanating from gaseous discharges. Aston invented his mass spectrograph (a new type of positive-ray apparatus) after WWI, with which he showed that many elements are mixtures of isotopes. In fact, he discovered 212 of the 287 naturally occurring nuclides. The mass spectrograph is now widely used in geology, chemistry, biology, and nuclear physics.
