Scientific American is an American popular science magazine. Many famous scientists, including Albert Einstein, have contributed articles to it, it is the oldest continuously published monthly magazine in the United States. Scientific American was founded by inventor and publisher Rufus M. Porter in 1845 as a four-page weekly newspaper. Throughout its early years, much emphasis was placed on reports of what was going on at the U. S. Patent Office, it reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, the universal joint which now can be found in nearly every automobile manufactured. Current issues include a "this date in history" section, featuring excerpts from articles published 50, 100, 150 years earlier. Topics include humorous incidents, wrong-headed theories, noteworthy advances in the history of science and technology. Porter sold the publication to Alfred Ely Beach and Orson Desaix Munn a mere ten months after founding it.

Until 1948, it remained owned by Company. Under Munn's grandson, Orson Desaix Munn III, it had evolved into something of a "workbench" publication, similar to the twentieth-century incarnation of Popular Science. In the years after World War II, the magazine fell into decline. In 1948, three partners who were planning on starting a new popular science magazine, to be called The Sciences, purchased the assets of the old Scientific American instead and put its name on the designs they had created for their new magazine, thus the partners—publisher Gerard Piel, editor Dennis Flanagan, general manager Donald H. Miller, Jr.—essentially created a new magazine. Miller retired in 1979, Flanagan and Piel in 1984, when Gerard Piel's son Jonathan became president and editor. In 1986, it was sold to the Holtzbrinck group of Germany. In the fall of 2008, Scientific American was put under the control of Nature Publishing Group, a division of Holtzbrinck. Donald Miller died in December 1998, Gerard Piel in September 2004 and Dennis Flanagan in January 2005.

Mariette DiChristina became editor-in-chief after John Rennie stepped down in June 2009, stepped down herself in September 2019. Scientific American published its first foreign edition in 1890, the Spanish-language La America Cientifica. Publication was suspended in 1905, another 63 years would pass before another foreign-language edition appeared: In 1968, an Italian edition, Le Scienze, was launched, a Japanese edition, Nikkei Science, followed three years later. A new Spanish edition, Investigación y Ciencia was launched in Spain in 1976, followed by a French edition, Pour la Science, in France in 1977, a German edition, Spektrum der Wissenschaft, in Germany in 1978. A Russian edition V Mire Nauki was launched in the Soviet Union in 1983, continues in the present-day Russian Federation. Kexue, a simplified Chinese edition launched in 1979, was the first Western magazine published in the People's Republic of China. Founded in Chongqing, the simplified Chinese magazine was transferred to Beijing in 2001.

In 2005, a newer edition, Global Science, was published instead of Kexue, which shut down due to financial problems. A traditional Chinese edition, known as Scientist, was introduced to Taiwan in 2002; the Hungarian edition Tudomány existed between 1984 and 1992. In 1986, an Arabic edition, Oloom Magazine, was published. In 2002, a Portuguese edition was launched in Brazil. Today, Scientific American publishes 18 foreign-language editions around the globe: Arabic, Brazilian Portuguese, Simplified Chinese, Traditional Chinese, Dutch, German, Hebrew, Japanese, Lithuanian, Romanian and Spanish. From 1902 to 1911, Scientific American supervised the publication of the Encyclopedia Americana, which during some of that period was known as The Americana, it styled itself "The Advocate of Industry and Enterprise" and "Journal of Mechanical and other Improvements". On the front page of the first issue was the engraving of "Improved Rail-Road Cars"; the masthead had a commentary as follows: Scientific American published every Thursday morning at No. 11 Spruce Street, New York, No. 16 State Street, No.

As a family newspaper, it will convey more useful intelligence to children and young people, than five times its cost in school instruction. Another important argument in favor of this paper, is that it will be worth two dollars at the end of the year when the volume is complete, (Old volumes of the New York

The Théols is a 42.3 km long river in central France. Its source is in the Boischaut natural region, it joins the Arnon near Lazenay. The flow of the river was studied from 1971 to 1975 at Sainte-Lizaigne, located about 10 km from its confluence with the Arnon. At this point it drains 797 km2, over 90% of its watershed; the river has an average flow of 2.99 m3/s at Sainte-Lizaigne. There are seasonal fluctuations in the flow of the Théols; the highest flow rates are from February with average flows from 3.5 to 5 m3/s. From April, the flow rate decreases toward low water, which lasts from August to October. Floods are important; the daily maximum flow recorded at Sainte-Lizaigne was 32.3 m3/s on March 22, 1974. Its yearly drainage basin precipitation is 118 mm, just over a third of the national average of 320 mm, below the average of for the Loire basin and the Arnon; the discharge was hence 3.75 l/s per km² of basin. The river is rich in bleak, largemouth bass, pike, roach, rudd, tench and catfish
