Alchemy or alchymy is the art which in former times occupied the place of and paved the way for the modern science of chemistry (as astrology did for astronomy), but whose aims were not scientific, being confined solely to the discovery of the means of indefinitely prolonging human life, and of transmuting the baser metals into gold and silver.
Among the alchemists it was generally thought necessary to find a substance which, containing the original principle of all matter, should possess the power of dissolving all substances into their elements. This general solvent, or menstruum universale, which at the same time was to possess the power of removing all the seeds of disease out of the human body and renewing life, was called the philosophers stone, lapis philosopherum, and its pretended possessors were known as adepts. Alchemy nourished chiefly in the middle ages, though how old might be such notions as those by which the alchemists were inspired it is difficult to say. The mythical Hermes Trismegistus of pre-Christian times was said to have left behind him many books of magical and alchemical learning, and after him alchemy received the name of the hermetic art.
At a later period chemistry and alchemy were cultivated among the Arabians, and by them the pursuit was introduced into Europe. Many of the monks devoted themselves to alchemy, although they were latterly prohibited from studying it by the popes. But there was one even among these, John XXII, who was fond of alchemy. Raymond Lully, or Lullius, a famous alchemist of the thirteenth and fourteenth centuries, is said to have changed for King Edward I a mass of 50,000 lbs of quicksilver (mercury) into gold, of which the first rose-nobles were coined.
Among other alchemists may be mentioned Paracelsus and Basilius Valentinus. With the growth of chemistry, the recognition of the chemical elements as forming a large number of distinct substances, and the conception of the fixed unalterable nature of the atoms, attempts to transform the base metals into gold were largely abandoned as being unscientific.

In mathematics, altitude is the perpendicular height of the vertex or apex of a plane figure or solid above the base.
In astronomy it is the vertical height of any point or body above the horizon. It is measured or estimated by the angle subtended between the object and the plane of the horizon, and may be either true or apparent. The apparent altitude is that which is obtained immediately from observation; the true altitude, that which results from correcting the apparent altitude, by making allowance for parallax, refraction, etc. Research Altitude
An anvil is an instrument on which pieces of metal are laid for the purpose of being hammered. The common smith's anvil is generally made of seven pieces, namely, the core or body; the four corners for the purpose of enlarging its base; the projecting end, which contains a square hole for the reception of a set or chisel to cut off pieces of iron; and the beak or conical end, used for turning pieces of iron into a circular form, etc. These pieces are each separately welded to the core and hammered so as to form a regular surface with the whole. When the anvil has received its due form, it is faced with steel, and is then tempered .in cold water. The smith's anvil is generally placed loose upon a wooden block. The anvil for heavy operations, such as the forging of ordnance and shafting, consists of a huge iron block deeply embedded, and resting on piles of masonry. Research Anvil
The Apollo Project was the US space project to land a person on the moon in order to prove to the world the ideological superiority of the American system over that of Communist Russia. It was reportedly achieved by Apollo 11 in July 1969. The three-stage vehicle to carry the astronauts to the moon was code named Saturn, and the contract to develop the Apollo three-man spacecraft was awarded to North American Aviation Incorporated in 1961 by NASA. The first launch into orbit of an Apollo command module was made by Saturn SA-6 on May the 28th 1964, and the first manned flight was made after a fire during ground tests killed the three astronauts - Virgil Grissom, Edward White and Roger Chaffee - on January the 27th 1967.
Controversy surrounds the supposed moon landing, with theories abounding that in 1969 it was technically impossible to land on the moon, and as a result NASA faked the moon landing, filming the 'landing' at the top secret military base, Area 51, in the Nevada desert while the astronauts actually orbited the earth for eight days before returning. This theory was later illustrated in the film 'Capricorn One' which told the fictional story of a faked landing on the planetMars. Research Apollo Project
Auto da fe (Act of Faith) was the ritual execution of heretics by the Inquisition after a confession had been extracted. The ceremony always took place on a Sunday, but not at regular intervals, maybe once every two, three or four years. The victims were walked in procession wearing the sanbenito, the coroza, the rope around the neck, and carrying a yellow waxcandle in their hand. The sanbenito was a penitential tunic of yellow cloth reaching to the knees and painted on it was a picture of the person who wore it, burning in flames with figures of dragons and devils in the act of fanning the flames. The costume indicated to the watching crowds the wearer was to be burned alive as an incorrigible heretic. If the person was only to do penance, then the sanbenito had on it a cross, and no painting or flames. If the victim was converted just before being led out, then the sanbenito was painted with the flames downward (known as fuego resuelto) and indicated that the wearer was not to be burned alive, but to be first strangled before burning.
At one time the sanbenito were hung up in the churches as monuments to the Inquisition. The coroza was a pasteboard cap, one metre high, ending in a point. On it were likewise painted crosses, flames and devils. Gags were kept on hand in case a victim insulted the tribunal or revealed what had occurred to them as they were led along to the place of execution where a large scaffold was erected.
The stake where the victim was to be burned varied in form, and was either a simple stake mounted in the ground, or was about three metres tall, with a small board near the top where the victim sat and was chained to the stake. Following prayers and attempts to convert the victim to the Roman Catholic faith, burning furzes were thrust into the face until the victim's face was burned before furzes around the base of the stake were ignited and the victim burned to death.
Victims were burned, because the inquisitors were forbidden to 'shed blood', the Roman Catholic church maintaining the line that it is untainted with blood. Research Auto da Fe

The chinook is the warm dry wind at the eastern base of the Rocky Mountains, and presents the same features as the fohn winds of Switzerland. The chinook winds descend from the Rockies, and while they are chiefly found in Montana and Wyoming, they also extend from the southern part of Colorado up into Canada as far as the Arctic circle. The high temperatures are confined to the valleys, and occur in streaks or pockets so that a traveller frequently passes suddenly from a very warm to a very cold atmosphere. Research Chinook
Enamel is a vitreous glaze of various colours fused to the surface of gold, silver, copper, and other substances. The art of enamelling, which is of great antiquity, was practised by the Assyrians and by the Egyptians, from whom it may have passed into Greece, and thence into Rome and its provinces, including Great Britain, where various Roman antiquities with enamelled ornamentation have been discovered. The enamelled gold cup given by King John to the corporation of Lynn, in Norfolk, proves that the art was known among the Normans. The Byzantines of the 10th century produced excellent cloisonne enamels on a gold base, the cloisonne process consisting in tracing the design in fillets of gold upon the gold plate and filling up the small moulds thus formed with enamels the design appearing in coloured enamels separated by thin gold partitions or cloisons. In some cases, however, the enamels were filled into hollows beaten out in the gold plate, which formed part of the field.
In the 12th century the town of Limoges acquired the high reputation for inlaid enamels which it held until the 14th century, aud re-acquired in the 16th for its painted enamels. The costliness of the sculptured ground had led the Italians early in the 14th century to substitute the practice of incising the design on the face of the plate, and then covering it with a transparent enamel. The further step, which made the Limousin workshops famous, consisted in the method of superficial enamelling, in which opaque colours or colours laid on a white opaque ground were used. The Limoges school degenerated greatly in the 17th century, but its method with certain modifications in detail is still employed.
The basis of all kinds of enamel is a perfectly transparent and fusibleglass, which is rendered either semitransparent or opaque by the admixture of metallic oxides. White enamels are composed by melting the oxide of tin with glass, and adding a small quantity of manganese or phosphate of calcium to increase the brilliancy of the colour. The addition of the oxide of lead, or antimony, or oxide of silver, produces a yellow enamel. Reds are formed by copper, and by an intermixture of the oxides of gold and iron. Greens, violets, and blues are formed from the oxides of copper, cobalt, and iron.
In the middle of the 18th century enamelling was largely applied to the decoration of snuff-boxes, tea-canisters, candlesticks, and other small articles. Of later years it was extensively applied to the coating of iron vessels for domestic purposes, the protection of the insides of baths, cisterns, and boilers, and the like. Enamelling in colours upon iron was common, iron plates being thus treated by means of various mixtures, and words and designs of various kinds being permanently fixed upon them by stencilling, for advertising, signboards, etc.
