On 24 Sep 1501, Girolamo Cardano was born, an Italian physician, mathematician, and astrologer who was the first to give a clinical description of typhus fever. His book, Ars magna (“Great Art,” 1545) was one of the great achievements in the history of algebra. His mechanical inventions included a combination lock, a compass gimbal and a universal joint.

A book-length biography was written by Henry Morley, who also contributed a magazine article on the life of Girolamo Cardano to The Gentleman's Magazine in the same year (1854). His article is a verbose exposition of the personal life of Cardarno, titled Jerome Cardan.

Quotations for Today
Thumbnail of Philippus Aureolus Paracelsus
Every creature has its own food, and an appropriate alchemist with the task of dividing it ... The alchemist takes the food and changes it into a tincture which he sends through the body to become blood and flesh. This alchemist dwells in the stomach where he cooks and works. The man eats a piece of meat, in which is both bad and good. When the meat reaches the stomach, there is the alchemist who divides it. What does not belong to health he casts away to a special place, and sends the good wherever it is needed. That is the Creator's decree... That is the virtue and power of the alchemist in man.
— Philippus Aureolus Paracelsus, German-Swiss physician and alchemist (died 24 Sep 1541). quote icon
Thumbnail of Robert John Kane
To produce any given motion, to spin a certain weight of cotton, or weave any quantity of linen, there is required steam; to produce the steam, fuel; and thus the price of fuel regulates effectively the cost of mechanical power. Abundance and cheapness of fuel are hence main ingredients in industrial success. It is for this reason that in England the active manufacturing districts mark, almost with geological accuracy, the limits of the coal fields.
— Robert John Kane, Irish chemist (born 24 Sep 1809). quote icon
Thumbnail of Sir Howard Walter Florey
It is the technologist who is transforming at least the outward trappings of modern civilization and no hard and fast line can or should be drawn between those who apply science, and in the process make discoveries, and those who pursue what is sometimes called basic science.
— Sir Howard Walter Florey, Australian-English pathologist (born 24 Sep 1898). quote icon

On 24 Sep 1852, a new invention, the dirigible - a semi-rigid airship - was demonstrated in a flight from Paris to Trappe. Henri Giffard (1825-82) designed in the gondola of a 147-foot-long spindle shaped coal-gas balloon. An 11 ft propeller produced a speed of 5 mph on a 3 hour trip. This was the first powered and controlled flight ever achieved.
What form of power turned the propeller?
