Solar Eclipse Of June 8, 1918
A total solar eclipse occurred on Saturday, June 8, 1918. The eclipse was viewable across the entire contiguous United States, an event which would not occur again until the solar eclipse of August, 2017. The path The path of totality started south of Japan, went across the Pacific Ocean, passing northern part of Kitadaitō, Okinawa and the whole Tori-shima in Izu Islands on June 9 (Sunday), and then acrossed the contiguous United States and British Bahamas (today's Bahamas) on June 8 (Saturday). The largest city to see totality was Denver, although many could theoretically see it as the size of the shadow was between across as it traveled across America. The longest duration of totality was in the Pacific at a point south of Alaska. The path of the eclipse finished near Bermuda. Besides the path where a total solar eclipse was visible, a partial solar eclipse was visible in the eastern part of East Asia, northern part of Northern Europe, eastern part of Micronesia, Hawaii I ...

Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Moon ...

Lesser Antilles
The Lesser Antilles ( es, link=no, Antillas Menores; french: link=no, Petites Antilles; pap, Antias Menor; nl, Kleine Antillen) are a group of islands in the Caribbean Sea. Most of them are part of a long, partially volcanic island arc between the Greater Antilles to the north-west and the continent of South America."West Indies." ''Merriam-Webster's Geographical Dictionary'', 3rd ed. 2001. () Springfield, MA: Merriam-Webster Inc., p. 1298. The islands of the Lesser Antilles form the eastern boundary of the Caribbean Sea where it meets the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles make up the Antilles. (Somewhat confusingly, the word Caribbean is sometimes used to refer only to the Antilles, and sometimes used to refer to a much larger region.) The Lesser and Greater Antilles, together with the Lucayan Archipelago, are collectively known as the West Indies. History after European arrival The Spanish were the first Europeans to arrive on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yerkes Observatory
Yerkes Observatory ( ) is an astronomical observatory located in Williams Bay, Wisconsin, United States. The observatory was operated by the University of Chicago Department of Astronomy and Astrophysics from its founding in 1897 to 2018. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May 2020, which began restoration and renovation of the historic building and grounds. Re-opening for public tours and programming began May 27, 2022. The observatory, often called "the birthplace of modern astrophysics," was founded in 1892 by astronomer George Ellery Hale and financed by businessman Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the early-20th-century concept of observation equipment integrated with laboratory space for physics and chemistry analysis. The observatory's main dome houses a doublet lens refracting telescope, the largest refractor ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jakob Kunz
Jakob Kunz (November 3, 1874 – July 18, 1938) was an American physicist who pioneered the development and application of photoelectric cells. Born in Brittnau, Switzerland, he earned his bachelor's degree in 1897 and his Ph.D in 1902 from the Eidgenossisches Polytechnikum in Zurich, and was active in the Baháʼí Faith from 1921. Physics department Kunz arrived at the University of Illinois in 1909 as a theoretical physicist. He taught most of the graduate courses and supervised half of the Ph. Ds up to 1929. Larazus notes that “He was clearly the intellectual leader of the department.” One of his students was E. Frances Seiler who became the first woman to earn a Ph.D in physics at Illinois for her thesis on the color-sensitivity of photoelectric cells. Kunz also wrote papers on and gave public lectures on relativity. Photoelectric cells and astronomical photometry Kunz made significant contributions to construction of photoelectric cells improving on the methods intro ...

Joel Stebbins
Joel Stebbins (July 30, 1878 – March 16, 1966) was an American astronomer who pioneered photoelectric photometry in astronomy. He was director of the University of Illinois Observatory from 1903 to 1922 where he performed innovative work with the selenium cell. In 1922 he became director of the Washburn Observatory at the University of Wisconsin–Madison where he remained until 1948. After 1948, Stebbins continued his research at Lick Observatory until his final retirement in 1958. Stebbins brought photoelectric photometry from its infancy in the early 1900s to a mature technique by the 1950s, when it succeeded photography as the primary method of photometry. He used the new technique to investigate eclipsing binaries, the reddening of starlight by interstellar dust, colors of galaxies, and variable stars. Biography Joel Stebbins was born in Omaha, Nebraska, on July 30, 1878, the son of Charles Stebbins, an office worker at the Union Pacific Railroad and his wife Sara Ann né ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Baker City, Oregon
Baker City is a city in and the county seat of Baker County, Oregon, United States. It was named after Edward D. Baker, the only U.S. Senator ever killed in military combat. The population was 10,099 at the time of the 2020 census. History Platted in 1865, Baker City grew slowly in the beginning. A post office was established on March 27, 1866, but Baker City was not incorporated until 1874. Even so, it supplanted Auburn as the county seat in 1868. The city and county were named in honor of U.S. Senator Edward D. Baker, the only sitting senator to be killed in a military engagement. He died in 1861 while leading a charge of 1,700 Union Army soldiers up a ridge at Ball's Bluff, Virginia, during the American Civil War. The Oregon Short Line Railroad came to Baker City in 1884, prompting growth; by 1900 it was the largest city between Salt Lake City and Portland and a trading center for a broad region.
