Julius Erasmus Hilgard
Julius Erasmus Hilgard (January 7, 1825 – May 8, 1891) was a Bavarian- American engineer. Biography Julius Erasmus Hilgard was born at Zweibrücken, Rhineland-Palatinate, Kingdom of Bavaria on January 7, 1825. His father, Theodore Erasmus Hilgard, was for many years Chief Justice of the Court of Appeals, but on account of his liberal opinions was so dissatisfied with conditions in his native country that in 1835 he emigrated to America. The journey from his native place to Havre was made in wagons. After a voyage of 62 days, the family landed at New Orleans at Christmas, and journeyed up the Mississippi to St. Louis, and thence to a farm at Belleville, Illinois. As the oldest son, Julius gave valuable help by his practical talents. His education was carried on at home. Music, chemistry, ancient and modern languages and mathematics (the higher branches of the latter being studied without outside help), occupied his attention until 1843, when he went to Philadelphia to study en ...

Zweibrücken
Zweibrücken (; ; , ; literally translated as "Two Bridges") is a town in Rhineland-Palatinate, Germany, on the Schwarzbach (Blies), Schwarzbach River.

Balfour Stewart
Balfour Stewart (1 November 182819 December 1887) was a Scottish physicist and meteorologist. His studies in the field of radiant heat led to him receiving the Rumford Medal of the Royal Society in 1868. In 1859 he was appointed director of Kew Observatory. He was elected professor of physics at Owens College, Manchester, and retained that chair until his death, which happened near Drogheda, in Ireland, on 19 December 1887. He was the author of several successful science textbooks, and also of the article on "Terrestrial Magnetism" in the ninth edition of the ''Encyclopædia Britannica''.

Geomagnetic Storms
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere that is driven by interactions between the magnetosphere and large-scale transient plasma and magnetic field structures that originate on or near the Sun. The structures that produce geomagnetic storms include interplanetary coronal mass ejections (CME) and corotating interaction regions (CIR). The former often originate from solar active regions, while the latter originate at the boundary between high- and low-speed streams of solar wind. The frequency of geomagnetic storms increases and decreases with the sunspot cycle. During solar maxima, geomagnetic storms occur more often, with the majority driven by CMEs. When these structures reach Earth, the increase in the solar wind pressure initially compresses the magnetosphere. The solar wind's magnetic field interacts with the Earth's magnetic field and transfers an increased energy into the magnetosphere. Both intera ...

Photography
Photography is the visual arts, art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who operates a camera to capture or take Photograph, photographs is called a photographer, while the captured image, also known as a photograph, is the result produced by the camera. Typically, a lens is used to focus (optics), focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed Exposure (photography), exposure. With an electronic image sensor, this produces an Charge-coupled device, electrical charge at each pixel, which is Image processing, electro ...

American Journal Of Science
The ''American Journal of Science'' (''AJS'') is the United States of America's longest-running scientific journal, having been published continuously since its conception in 1818 by Professor Benjamin Silliman, who edited and financed it himself. It was initially called the ''American Journal of Science and Arts'' until a name change in 1880, but its focus was always on natural sciences and especially on geology and related subjects. In early years, the journal was often referred to as "Silliman's Journal", and the publication became associated with Yale University due to his long tenure there (1804–1853). The editorship long remained in the family of Professor Silliman, as he was assisted by his son, Benjamin Silliman Jr., from 1838. On the death of the elder Silliman in 1864, he was succeeded as chief editor by his son-in-law, James Dwight Dana, and then from 1895 till 1926 by Dana's son Edward Salisbury Dana.
