Because of their softness, coinage metals are easily fashioned into coins. Their comparative rarity and attractiveness, along with their resistance to corrosion, make them compact stores of wealth. However, pure copper is too soft to have structural value, but copper alloys with zinc and tin to form harder brasses and bronzes. Brass and bronze were essential components of the earliest metal tools. Copper is the most heavily used of the coinage metals due to its electrical properties, its abundance compared to silver and gold , and the properties of its brass and bronze alloys. Until aluminum became commonplace, copper was second only to iron in production among the metals.

Das Grab im Busento. Mythical Concepts of Human Ages. There are many attempts to bring order into human history by defining "ages" or periods that have some common denominator. It goes without saying that whoever made that attempt was biased by his or her own culture and history. That's why I and everybody else from the "western" world have usually only heard about " ages of man " as defined by western guys and by western thought.

As usual in Western culture , one starts with the ancient Greeks. People and Gods lived together in harmony, nobody had to work, and peace prevailed. Hesiod obviously was a writer of "fantasy" stuff. Silver Age. Men in the Silver age lived for one hundred years under the dominion of their mothers and not quite as peacefully and harmonious as in the golden age.

As much as I love my mother, I tend to agree. Can't be all that harmonious and peaceful. Bronze Age. Things are more modern. War was common, arms, tools and even houses were forged of bronze. People after death went to "Hades", a kind of hell. Heroic Age. Things improved partially. Demigods and heroes did noble deeds. Humans died and went on occasion to "Elysium", a kind of paradise.

Iron Age. The age Hesiod lived in. Complete disaster, everything goes down the drain. A bit like modern Greece today In other words: Things were always better in the past, also known as "the good old times". This viewpoint wasn't new in BC. You may laugh at this but Hesiod's "ages" was influential to the way people perceived themselves and to the arts for a long time. After the old Greeks we look to the old Romans.

He also ties the remaining four ages a bit more to the development of civilization and technology. Like all elderly persons he shared Hesiod's opinion that things became worse as he grew older. The early Christians certainly had to say something about this too.

Of course, the less you actually know about what you are writing, the more you tend to give numbers with many digits and thus supposed precision. Saint Jerome started a time-honored tradition here that is still alive and thriving.

Saint Augustine - begged to differ. He conceived Six Ages that actually had some roots in the Jewish tradition. His ideas became central to the church. Augustine's six ages of history, with each age lasting approximately years, were widely believed to be factual and thus dominated the writing of history in the Middle Ages. Here they are: First Age : from the beginning of the human race; i.

Second Age : from Noah to Abraham. Third Age : from Abraham to King David. Fourth Age : from David to the captivity of the Jews in Babylonia. Fifth Age : from Babylonia to the advent of Jesus Christ. Sixth Age : coming of Christ to now.

Tough luck that the sixth age lasts already more than 2. What we learn from this is that medieval history, including art and sword lore, is often deeply rooted in wishful thinking or plain nonsense. One should bear that in mind when contemplating old stories about iron, steel and swords. In stark contrast to Augustine's years per age, the Indians allow a grant total of 4. Interestingly, as far as metals are associated with ages, there seems to be a general agreement that a golden age is the best, and an iron age is the worst.

Considering that gold is utterly useless except for displaying wealth and power, while iron is extremely useful to all of us who must work for a living, it becomes clear what kind of people came up with those "human age" concepts. Not the kind like you and me that had to work for a living, but the kind who took away the fruits of our and our forebears labor in exchange for letting us live. Once more it is important to bear in mind that history in general was written by the winners. Be it the winners in a war or just in the race for social settings, ranks or class.

Scientific Concepts of Human Ages. Just to be clear: the scientific concept of Human Ages is not all that scientific either.

The idea was to classify general human development by the progress made in material development for tools. In reality, the concept of Human Ages served mainly as a battle ground for various budding scientists in the 19th century. Untold pages to the topic can be found in the Net. Take this quote from the very entertaining wikipedia page " Three-age system ":. Bertrand that no distinct age of bronze had existed, that the bronze artifacts discovered were really part of the Iron Age.

Hans Hildebrand in refutation pointed to two Bronze Ages and a transitional period in Scandinavia.

The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A. They are sometimes called the d -block elements , since in this region the d -orbitals are being filled in, and are also referred to as B-group elements since in most numbering systems of the columns on the periodic table the numerals of these groups are followed by the letter B. The period 7 transition metals are the naturally-occurring actinium Ac , and the artificially produced elements rutherfordium Rf , dubnium Db , seaborgium Sg , bohrium Bh , hassium Hs , meitnerium Mt , darmstadtium Ds , roentgenium Rg , and the as-yet unnamed ununbiium Uub. In the transition metals, the five d orbitals are being filled in, and the elements in general have electron configurations of n -1 d ns 2 , although there are some exceptions when electrons are shuffled around to produce half-filled or filled d subshells.

An alloy is a material made by melting one or more metals together with other elements. This is an alphabetical list of alloys grouped according to base metal. Some alloys are listed under more than one element, since the composition of the alloy may vary such that one element is present in a higher concentration than the others. Share Flipboard Email.

Pustak Mahal Editorial Group. It is a common sentiment expressed by many students from time to time. The answer to this is simple. Taking an exam is an art and only he who approaches the task in a more systematic and scientific manner comes out a winner. One common aspect of the exam-taking strategy is revision.
