Thumbnail of Srinivasa Ramanujan

On 22 Dec 1887, Srinivasa Ramanujan was born in India, where he taught himself mathematics to a level regarded as genius without formal training. He introduced himself by letter, with some of his mathematical work, to Cambridge mathematician G.H. Hardy, who recognized the talent shown in the papers he received. Ramanujan was invited to travel to England for a research scholarship at Cambridge. After three years of a productive collaboration with Hardy, Ramanujan took ill, and never really recovered. So he returned home to India, where he subsequently died on 26 Apr 1920, having reached the age of only 32. The cause has been commonly attributed, but perhaps misattributed, to tuberculosis. But some shrewd analysis of remaining documentation of Ramanujan's medical records studied by D.A.B. Young was published in Jan 1994. The detective work to come up with a more satisfactory diagnosis reads like a mystery story. In The Mystery of Srinivasa Ramanujan's Illness you can trace a possible answer to whether it was tuberculosis, or something else that could have been cured, and saved one of the most remarkably gifted mathematicians to complete more of the research that he had started. Ramanujan remains a national hero in India, and his death at an early age is mourned. It remains a mystery both tantalizing and sad.


Book of the Day
The Man Who Knew Infinity: A Life of the Genius Ramanujan

On 22 Dec 1887, Srinavasa Ramanujan was born in India, a remarkably gifted mathematician, who died at age 32, leaving rich lode of original mathematics that is still being mined today. He has since beome a folk hero in his native country. Today's book pick is: The Man Who Knew Infinity: A Life of the Genius Ramanujan, by Robert Kanigel, whose biography traces Ramanujan as a self-taught mathematical prodigy whose prowess was recognised and fostered by eminient English mathematician G. H. Hardy, after which his work was brought to the attention of the world.

Quotations for Today
Thumbnail of Srinivasa Ramanujan
Replying to G. H. Hardy’s suggestion that the number of a taxi (1729) was “dull”: No, it is a very interesting number; it is the smallest number expressible as a sum of two cubes in two different ways, the two ways being 1³ + 12³ and 9³ + 10³.
— Srinivasa Ramanujan, Indian mathematician (born 22 Dec 1887). quote icon
Thumbnail of Constantin Fahlberg
How did I discover saccharin? Well, it was partly by accident and partly by study. I had worked a long time on the compound radicals and substitution products of coal tar... One evening I was so interested in my laboratory that I forgot about my supper till quite late, and then rushed off for a meal without stopping to wash my hands. I sat down, broke a piece of bread, and put it to my lips. It tasted unspeakably sweet. I did not ask why it was so, probably because I thought it was some cake or sweetmeat. I rinsed my mouth with water, and dried my moustache with my napkin, when, to my surprise the napkin tasted sweeter than the bread. Then I was puzzled. I again raised my goblet, and, as fortune would have it, applied my mouth where my fingers had touched it before. The water seemed syrup. It flashed on me that I was the cause of the singular universal sweetness, and I accordingly tasted the end of my thumb, and found it surpassed any confectionery I had ever eaten. I saw the whole thing at once. I had discovered some coal tar substance which out-sugared sugar. I dropped my dinner, and ran back to the laboratory. There, in my excitement, I tasted the contents of every beaker and evaporating dish on the table.

Why should we look to the past in order to prepare for the future? Because there is nowhere else to look.

Grote Reber, born 22 Dec 1911, was a U.S. astronomer and engineer who built the first of a new type of telescope and was largely responsible for the early development of a new branch of astronomy, opening an entirely new research front in the study of the universe.

Thumbnail of Constantin Fahlberg
On 22 Dec 1850, Constantin Fahlberg was born, a Russian chemist who, while working for Ira Remsen on coal tar compounds, discovered saccharin. The compound is 220 times sweeter than sugar. The factory he established manufactured it by the the ton, making him wealthy.
In which country did Constantin establish his first factory for saccharin?

Thumbnail of William Hyde Wollaston
William Hyde Wollaston (1766-1828) was a British scientist whose original powder-metallurgy techniques served as a model for the modern industrial processing of platinum, tungsten, molybdenum, and other transition metals. His studies of platinum also resulted in his discovery of two related elements.
What were the two elements he discovered?

John Holter (1916-2003) was an American inventor a medical device used in the treatment of hydrocephalus. His motivation was the need to treat his son who had that conditin develop whortly after birth. He refined and patented the device, which subsequently helped millions around the world since the late 1950s.

On 22 Dec 1885, the first U.S. patent for a switchback railway was issued to L.A. Thompson. It began in 1884, when La Marcus Thompson, the “Father of the Gravity Ride,” opened a 600-foot switchback railway. With a top speed of six miles per hour, Thompson's ride was little more than a leisurely, gravity-powered tour of the beach.
Where did Thompson open his first switchback railway?
