This song gained immense popularity after being used in a trailer for Assassin's Creed: Revelations.

Iron

Iron is a chemical element with symbol Fe (from ) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where the production of nickel-56 (which decays to the most common isotope of iron) is the last nuclear fusion reaction that is exothermic. Consequently, radioactive nickel is the last element to be produced before the violent collapse of a supernova, which scatters this precursor radionuclide of stable iron into space.

Like the other group 8 elements, ruthenium and osmium, iron exists in a wide range of oxidation states, −2 to +6, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly known as rust. Unlike the metals that form passivating oxide layers, iron oxides occupy more volume than the metal and thus flake off, exposing fresh surfaces for corrosion.

Iron metal has been used since ancient times, although copper alloys, which have lower melting temperatures, were used even earlier in human history. Pure iron is relatively soft, but is unobtainable by smelting because it is significantly hardened and strengthened by impurities, in particular carbon, from the smelting process. A certain proportion of carbon (between 0.002% and 2.1%) produces steel, which may be up to 1000 times harder than pure iron. Crude iron metal is produced in blast furnaces, where ore is reduced by coke to pig iron, which has a high carbon content. Further refinement with oxygen reduces the carbon content to the correct proportion to make steel. Steels and iron alloys formed with other metals ( alloy steels) are by far the most common industrial metals because they have a great range of desirable properties and iron-bearing rock is abundant.

Iron chemical compounds have many uses. Iron oxide mixed with aluminium powder can be ignited to create a thermite reaction, used in welding and purifying ores. Iron forms binary compounds with the halogens and the chalcogens. Among its organometallic compounds is ferrocene, the first sandwich compound discovered.

Iron plays an important role in biology, forming complexes with molecular oxygen in hemoglobin and myoglobin; these two compounds are common oxygen transport proteins in vertebrates. Iron is also the metal at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals. A human male of average height has about 4 grams of iron in his body, a female about 3.5 grams. This iron is distributed throughout the body in hemoglobin, tissues, muscles, bone marrow, blood proteins, enzymes, ferritin, hemosiderin, and transport in plasma.

Iron (golf)

An iron is a type of club used in the sport of golf to propel the ball towards the hole. Irons typically have shorter shafts and smaller clubheads than woods, the head is made of solid iron or steel, and the head's primary feature is a large, flat, angled face, usually scored with grooves. Irons are used in a wide variety of situations, typically from the teeing ground on shorter holes, from the fairway or rough as the player approaches the green, and to extract the ball from hazards, such as bunkers or even shallow water hazards.

Irons are the most common type of club; a standard set of 14 golf clubs will usually contain between 7 and 11 irons, including wedges. Irons are customarily differentiated by a number from 1 to 10 (most commonly 3 to 9) that indicates the relative angle of loft on the clubface, although a set of irons will also vary in clubhead size, shaft length, and hence lie angle as the loft (and number) increase. Irons with higher loft than the numbered irons are called wedges, which are typically marked with a letter indicating their name, and are used for a variety of "utility" shots requiring short distance and/or a high launch angle.

Usage examples of "iron".

Hence the sulphuretted hydrogen must be boiled off and the iron removed as basic ferric acetate by the method described on p.

The small quantity of white flocculent precipitate which may be observed in the acetic acid solution before titrating, contains the whole of the iron as ferric arsenate.

The iron is reduced to the ferrous state and phosphate of alumina precipitated in an acetic acid solution.

In the case of ferric salts, half the quantity of acetic acid will be better, as then the ferric iron will be precipitated, and a colourless solution will be left, in which the end reaction is more readily distinguished.

He had been with Mwynwen frequently, either in his own chambers or her house, resting and leaching out of his body the subliminal aches and slight sickness that extended exposure to iron caused .

Vesta resembles a kind of meteorite called a basaltic achondrite, while 16 Psyche and 22 Kalliope appear to be largely iron.

Venerian lives upon the bottom of an everlasting sea of fog and his thin epidermis, utterly without pigmentation, burns and blisters as frightfully at the least exposure to actinic light as does ours at the touch of a red-hot iron.

Sheets of immeasurable fire, and veins Of gold and stone, and adamantine iron.

The specific treatment, which should not be omitted, consists in administering doses of ten drops of the tincture of the muriate of iron in alternation with teaspoonful doses of the Golden Medical Discovery, every three hours.

Mourzoufle, an iron mace in his hand, visiting the posts, and affecting the part and aspect of a warrior, was an object of terror to his soldiers, at least, and to his kinsmen.

Juss, enforcing his half frozen limbs to resume the ascent, beheld a sight of woe too terrible for the eye: a young man, helmed and graithed in dark iron, a black-a-moor with goggle-eyes and white teeth agrin, who held by the neck a fair young lady kneeling on her knees and clasping his as in supplication, and he most bloodily brandishing aloft his spear of six foot of length as minded to reave her of her life.

Broken stone and iron gashed her bare feet as she plunged into the black arch of the gate, but the pain was swallowed in icy fear as thin, aimless winds tugged at heras she sensed, rather than saw, something move in the utter blackness over her head.

A squalid alameda where there stood a rotting brushwood gazebo and a few old iron benches.

The largest of those was taller than Alayne, with iron bands girding its dark brown staves.

Twenty minutes later, Jake sat waist-deep in a steaming galvanized iron bath, set out alfresco under the mahogany trees.
