Vicksburg is a historic city in Warren County, Mississippi, United States. It is the county seat, and the population at the 2010 census was 23,856. Located on a high bluff on the east bank of the Mississippi River across from Louisiana, Vicksburg was built by French colonists in 1719, and the outpost withstood an attack from the native Natchez people. It was incorporated as Vicksburg in 1825 after Methodist missionary Newitt Vick. During the American Civil War, it was a key Confederate river-port, and its July 1863 surrender to Ulysses S. Grant, along with the concurrent Battle of Gettysburg, marked the turning-point of the war.

Texas School For The Blind And Visually Impaired
The Texas School for the Blind and Visually Impaired (TSBVI) is a Texas special public school, in the continuum of statewide placements for students who have a visual impairment. It is considered a statewide resource to parents of these children and professionals who serve them. Students, ages 6 through 21, who are blind, deafblind, or visually impaired, including those with additional disabilities, are eligible for consideration for services at TSBVI. Founded in 1856, the school is currently located at 1100 West 45th Street in Austin and serves not only the local community but also most of the blind children in other schools across the state. The school has special equipment and classroom routines tailored to blind students, and according to a 2008 ''Texas Monthly'' article, blind students who previously attended ordinary public schools had a positive reception to TSBVI after enrolling there. It is the subject of a documentary, ''The Eyes of Me''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braille Typewriter
Braille (Pronounced: ) is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era. Braille characters are formed using a combination of six raised dots arranged in a 3 × 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Vicksburg, Mississippi
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
