William Jackson Humphreys
William Jackson Humphreys (February 3, 1862 – November 10, 1949) was an American physicist and atmospheric researcher. Biography Humphreys was born on February 3, 1862, in Gap Mills, West Virginia to Jackson and Eliza Ann (née Eads) Humphreys. He studied physics at Washington & Lee University in Virginia and later at Johns Hopkins University in Baltimore, where he earned his Ph.D. in 1897, studying under Henry Augustus Rowland. He worked in the fields of spectroscopy, atmospheric physics and meteorology. In the field of spectroscopy he found the shift of spectral lines under pressure. In atmospheric physics he found a very good model for the stratosphere in 1909. He wrote numerous books, including a textbook titled ''Physics of the Air'', first published in 1920 and considered a standard work of the time, though it was last published in 1940. He also held some teaching positions at universities. He concluded that the 1815 eruption of Mount Tambora was responsible for the ...

Year Without A Summer
The year 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by . Summer temperatures in Europe were the coldest on record between the years of 1766–2000. This resulted in major food shortages across the Northern Hemisphere. Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in April in the Dutch East Indies (known today as Indonesia). This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536), and was perhaps exacerbated by the 1814 eruption of Mayon in the Philippines. Description The Year Without a Summer was an agricultural disaster. Historian John D. Post has called this "the last great subsistence crisis in the Western world".Evans, RoberBlast from the Past ''Smithsonian Magazine''. July 2002, p. 2 The climatic aberrations of 1816 had their great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame". History Felix Klein and Georg Cantor are credited with putting forward the idea of an international congress of mathematicians in the 1890s.A.
