Gold

Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Gold's atomic number of 79 makes it one of the higher atomic number elements that occur naturally in the universe. It is thought to have been produced in supernova nucleosynthesis from the collision of two neutron stars and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was just formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is present today in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the late heavy bombardment, about 4 billion years ago.

Hello

Hello is a salutation or greeting in the English language. It is first attested in writing from 1833.

First use

Hello, with that spelling, was used in publications as early as 1833. These include an 1833 American book called The Sketches and Eccentricities of Col. David Crockett, of West Tennessee, which was reprinted that same year in The London Literary Gazette.

The word was extensively used in literature by the 1860s.

Etymology

According to the Oxford English Dictionary, hello is an alteration of hallo, hollo, which came from Old High German "halâ, holâ, emphatic imperative of halôn, holôn to fetch, used especially in hailing a ferryman." It also connects the development of hello to the influence of an earlier form, holla, whose origin is in the French holà (roughly, 'whoa there!', from French là 'there'). As in addition to hello, halloo,hallo, hollo, hullo and (rarely) hillo also exist as variants or related words, the word can be spelt using any of all five vowels.

Telephone

The use of hello as a telephone greeting has been credited to Thomas Edison; according to one source, he expressed his surprise with a misheard Hullo.Alexander Graham Bell initially used Ahoy (as used on ships) as a telephone greeting. However, in 1877, Edison wrote to T.B.A. David, the president of the Central District and Printing Telegraph Company of Pittsburgh:

Hello (magazine)

Hello (stylised as HELLO!) is a weekly magazine specialising in celebrity news and human-interest stories, published in the United Kingdom since 1988. It is sister magazine to ¡Hola!, the Spanish weekly magazine launched in Spain in 1944. ¡HOLA! Spanish, Hello UK, and ¡HOLA! Mexican – launched in 2006 – make up the magazines published by HOLA, S.A and distributed in over 100 countries. Local editions of the magazine are also published in Argentina, Bulgaria, Canada, Colombia, Dominican Republic, Ecuador, Estonia, Greece, India, Indonesia, Malaysia, the Middle East, Morocco, Nigeria, Pakistan, Peru, Puerto Rico, Russia, Serbia, Thailand, Turkey and Venezuela.

History

Hello was launched in 1988 by publisher Eduardo Sánchez Junco, owner and chairman of Spain's groundbreaking ¡HOLA! magazine. ¡HOLA! was created in 1944 by husband and wife Antonio Sánchez Gómez and Mercedes Junco Calderón. They wanted to create a light-hearted magazine that focused on weddings, new babies, new loves, and other people-centered, personal stories. Antonio Sánchez Gómez felt that "things of human interest would have pride of place in the magazine, and people more than things." From the beginning, ¡HOLA! regularly sold out and built a reputation for elegance and good taste.
