Place of birth

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
 Metamorphosis is iodothyronine-induced and an ancestral feature of all chordates.
 Some insects, fishes, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior.
 Animals that go through metamorphosis are called metamorphoses .
 Animals can be divided into species that undergo complete metamorphosis ("holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis ("ametaboly").
Metamorphosis is the name of a stage illusion invented by John Nevil Maskelyne, but most often associated with famous escape artist Harry Houdini and performed to some renown (for speed) by The Pendragons, among others.
 It is also known amongst magicians as the Substitution Trunk (often abbreviated to Sub Trunk).
Müller was born in 1740 or 1742 in the Habsburg Empire.
 While the "Allgemeine Deutsche Biographie" gives 1 July 1740 and Vienna as date and place of birth, the "Neue Deutsche Biographie" prefers 4 October 1742 and the small town of Poysdorf in Lower Austria.
 The much older works "Neuer Nekrolog der Deutschen" and "Oesterreichische National-Encyklopädie" do not give a place of birth and only the year 1740 for his birth.
 Even articles by Mary Elvira Weeks on the discovery of tellurium, published in the Journal of Chemical Education in 1932, and 1935 quote two different locations of his birth: one in Vienna and the other Hermannstadt (Sibiu) Transylvania, present day Romania.
 A newer biography on the topic makes clear that date and place of birth are not definitely known.
Whipple's index (or index of concentration), invented by American demographer George Chandler Whipple (1866–1924), is a method to measure the tendency for individuals to inaccurately report their actual age or date of birth.
 Respondents to a census or other survey sometimes report their age or date of birth as a round number (typically ending in 0 and 5), or to be more culturally favorable, for example, so that they appear younger or to have been born on a date considered luckier than their actual date of birth.
Swans Reflecting Elephants (1937) is a painting by the Spanish surrealist Salvador Dalí.
 This painting is from Dalí's Paranoiac-critical period.
 Painted using oil on canvas, it contains one of Dalí's famous double images.
 The double images were a major part of Dalí's "paranoia-critical method", which he put forward in his 1935 essay "The Conquest of the Irrational".
 He explained his process as a "spontaneous method of irrational understanding based upon the interpretative critical association of delirious phenomena."
 Dalí used this method to bring forth the hallucinatory forms, double images and visual illusions that filled his paintings during the Thirties.
 As with the earlier "Metamorphosis of Narcissus", "Swans Reflecting Elephants" uses the reflection in a lake to create the double image seen in the painting.
 In "Metamorphosis", the reflection of Narcissus is used to mirror the shape of the hand on the right of the picture.
 Here, the three swans in front of bleak, leafless trees are reflected in the lake so that the swans' necks become the elephants' trunks and the trees become the legs of the elephants.
 In the background of the painting is a Catalan landscape depicted in fiery fall colors, the brushwork creating swirls in the cliffs that surround the lake, to contrast with the stillness of the water.
Hilary Duff: All Access Pass is the first video album by American recording artist Hilary Duff, released on November 4, 2003 by Buena Vista and Hollywood Records.
 Directed and produced by Virgil P. and Tess Gallagher Thompson, the hour-long DVD features the music videos for Duff's songs "So Yesterday", "Why Not" and "I Can't Wait".
 "All Access Pass" also features behind-the-scenes videos of the former two music videos and her second studio album "Metamorphosis" (2003), and a live performance from Duff at Sessions@AOL.
 Duff has stated that the DVD also documents her two-year musical journey leading up to the release of "Metamorphosis".
 To date, it has been certified double platinum in the United States and five-times platinum in Canada.
Harry Houdini (born Erik Weisz, later Ehrich Weiss or Harry Weiss; March 24, 1874 – October 31, 1926) was an Austro-Hungarian-born American stage magician and stunt performer, noted for his sensational escape acts.
 He first attracted notice in vaudeville in the US and then as "Harry Handcuff Houdini" on a tour of Europe, where he challenged police forces to keep him locked up.
 Soon he extended his repertoire to include chains, ropes slung from skyscrapers, straitjackets under water, and having to escape from and hold his breath inside a sealed milk can with water in it.
John Ramsay (13 March 1877 – 19 January 1962) was a Scottish magician.
 He has been described, by Alex Proctor, former President of the Scottish Conjurers' Association, as a "magician's magician, who loved to trick fellow conjurers".
The California Birth Index (CABI) is a database compiled by the California Office of Health Information and Research.
 The index contains birth records of all registered births in California between 1905 and 1995.
 Each record is an abstract of a person's birth certificate, including date of birth, full name, county of birth, gender, and mother's maiden name.
 People who have been adopted are sometimes listed by their birth name, sometimes listed by their adopted name, sometimes by both and sometimes not listed at all.
 The CABI is considered a valuable genealogy tool but is also criticized for privacy issues.
 California began statewide civil registration of births on July 1, 1905.
 Earlier birth records may exist in the county where the birth took place or at the church where a baptism took place.
The place of birth (POB) is the place where a person was born.
 This place is often used in legal documents, together with name and date of birth, to uniquely identify a person.
 As a general rule with respect to passports, the place of birth is determined to be country that currently has "sovereignty" over the actual place of birth regardless of when the birth actually occurred.
 The place of birth is not necessarily the place where the parents of the new baby live.
 If the baby is born in a hospital in another place, that place is the place of birth.
 In many countries, this also means that the government requires that the birth of the new baby is registered in the place of birth.
