The Beginnings Of Jewelry

The Beginnings Of Jewelry Jewelry is as old as the history of man, dating back from cave–dwelling times in South Africa some 100,000 years ago in the form of seashells being tied about the neck. Man's original jewelry was also composed of teeth, carved stone, wood and bone. Function follows form as this type of jewelry was most likely used to tie loose clothing to the body and progressed to an aesthetic type of adornment. In much of the history of jewelry, the wearer displayed status and wealth by ornamenting the body with jewelry. Cro–Magnon man began making jewelry when migration to Europe from the Middle East transpired, 40,000 years ago. Metallurgy, the use of metals for jewelry making, appeared 7,000 years ago in the form of copper adornments.

The Ancient Egyptians along the Nile Delta began using gold for thousands of years, dating to 5,000 years ago. Jewelry was symbolic of authority and religious supremacy for many kings, queens and empires. The Egyptian men and women began wearing scarab beetles as sacred articles and protection from evil spirits. Scarab beetles represented rebirth, from the behavior of the dung beetle rolling its dung and incubating its young in this dung ball. The Egyptians used jewelry to adorn dead bodies which helped the dead in journeying into the afterlife, providing comfort and protection. Many tomb–raiders recycled jewelry by plundering tomb jewelry and adorning new kings. Pharaoh Tuntankhamen (King Tut) stands in history as the most famous jewelry–clad king although his 9 year reign from 1336–1327BC was fairly insignificant and most likely his tomb was forgotten when the Egyptians cleaned out the gravesites of other kings. Egyptians ascribed symbolic meaning to the color of gemstones. Green glass or gemstones were the symbols of fertility and was used to ensure the abundance of new crops. In the Book of the Dead it is written that the God Isis must be represented by a red stone or glass, worn as a figurative ornament on a necklace to provide Isis with blood. The Egyptians imported silver and lapis lazuli from Afghanistan, which was used in many forms of jewelry. Queen Cleopatra was enamored with emeralds which was mined in the area of the Red Sea.

In the ancient city of Ur, located in southern Mesopotamia between the Tigris and Euphrates rivers, jewelry became a significant product to craft and trade. The people of Ur created amulets, necklaces, ankle bracelets and cylinder seals made of fine gold leaf and set with brilliantly colored agate, carnelian, lapis lazuli and jaspter stones. This jewelry was very popular and both men and women elaborately bejeweled themselves. Gem carving or glyphic art was popularized as children and women wore rings with beautifully carved stones. Mesopotamian jewelers invented some of the techniques still used in jewelry making and metal work today such as granulation, filigree, cloisonné and engraving. The motifs and designs depicted on Mesopotamian jewelry included cones, spirals, grapes and leaves. The jewelry of the times was worn by humans and used additionally to embellish idols and statues in reverence.

History of Welding and Metallurgy - Part 1

History of Welding and Metallurgy Part 1 For you students out there doing a report on the history of welding, let me first say this…I have always found the earliest history of welding to be kind of boring. But I remember back to high school when my ears perked up in history class at the first mention of longbows. So I will try to make this interesting by talking about swords and airplanes.

This is actually more like the history of metallurgy. I will save the history of welding for Part 2

Let's get the boring stuff out of the way first. None of these dates are hard facts and I am probably going to omit some important terms like «Paleolithic» but that's how we roll up in here. So Here goes.

From the very beginning of mankind, up until about 8000 BC, was known as the Stone age.

Up until about 8000 BC, stone was used to make cutting tools and spear heads and things like that. Even though copper was discovered during the stone age, it was too soft to use for tools and weapons.

Around 3500 BC, someone discovered that adding tin to copper produced a much harder metal than pure copper and that began what is known as the Bronze Age.

Bronze swords and knifes were used until around 1500 BC when the process of refining iron ore into useable iron was discovered. Then began the iron age.

So this timeline gives a basic view of what makes up the stone age, bronze age, and iron age.

Boring right? Well think about this… not every country, tribe, or race discovered iron at the same time.

Let's say you are living in the city of Troy. You are a foot soldier and you have the latest and greatest bronze sword at your side. You think you are high tech. Your shield is also made out of bronze and easily stops the strongest of blows from other bronze swords .

You are making ready for battle when you get a report from a scout that the neighboring Trojans have developed a magic metal sword that will cut your sword in half and that will penetrate your shield.

You shrug it off as war propaganda but that little tidbit of information lingers in the back of your mind.

It's time to go to war now. Your adrenaline is pumping, war cries are heard, horns are blown and you rush the enemy. You expect certain victory but when you start tripping over your own soldiers and notice they are holding shiny bronze swords that have been cut in half, you remember the story about the magic metal. Oh snap!

It's a bad day for the guys with the bronze swords when they go into battle against iron swords.

I hope things are becoming a little less boring…

Now Fast forward to 2009. A fighter pilot flying an F 22 raptor is about to engage in a dogfight. He knows there are limits to how much throttle he can give to out maneuver his enemy. Too much throttle under the wrong conditions will overtemp the turbine blades and make them soft and unstable and maybe even blow up the motor.

And what if his enemy is flying a fighter jet that uses a new alloy that would allow for an increase of several hundred degrees before they reached overtemp condition? He could put the hammer down without worrying about overtemping.

Would that give a pilot a distinct advantage? It might be just like a bronze sword against an iron sword.

The more things change the more they stay the same.

Expectations of an Ordinary Person

Expectations of an Ordinary Person The way one lyrist has written, «Hum logo ko samajh sako to samjho dilbar jaani; jitna bhi tum samjhoge utni hogi hayerani»…in a nut–shell we Indian's are most «unpredictable». When the expectations are low…we have performed really well and contrary to that when expectations were very high…most of the time we have failed to live up to those expectations.

As we are going to complete 58 yrs of independence on 15th August 2005, it is a pleasure to share with you the facts about India, Vision India 2025 (From Ordinary person's point of View), and India in 21st Century.

From Independence…till now

India was a British colony. It earned its independence from the British on 15th August 1947. Day before that Pakistan which was created as a result of partition of British India was established and flanked on two sides of India: West Pakistan which is called today Pakistan, and east Pakistan, now an independent state called Bangladesh. After its independence, the political leaders of India adopted the liberal democratic system for the country.

Since its independence, India has transformed a lot. When India attained independence in 1947, its population was around 400 million people. Now there are billion people in India. India is the largest democracy in the world. It has the biggest number of people with franchise rights and the largest number of Political Parties, which take part in election campaign.

Before its independence, India was never a single country but a bunch of different entities. Many predicted that India, because of diversities in its cultures, religion, languages, castes, manners, local histories, nationalities and identities, would not survive as a single democratic country, but would break up into smaller countries.

Since independence, India had many political problems. During independence the most burning issues were the riots between the Hindus and Muslims while the Sikhs were siding with Hindus. Another issue was convincing the Princely states not to declare independence or join Pakistan but to join the Indian Union. India also had a few wars with its neighbors on border issues.

India also has many internal problems. Different communities with different identities – regional, language, caste, religion – demanded different rights for their communities. Some communities demanded more autonomy for their cultures within the Indian states. Others demanded autonomous states within the Indian Union, while the others demanded to be independent from India.

With all its problems India survives as a single state with democratic character.

How much do you know about India? (India – Fact File)

Location: Southern Asia, bordering the Arabian Sea and the Bay of Bengal, between Burma and Pakistan

Population: 1,080,264,388 (July 2005 est.)

Population Growth Rate: 1.4% (2005 est.)

Life expectancy: 64.35 years

Sex ratio: 1.06 male(s)/female (2005 est.)

Composition of Religion: Hindu 80.5%, Muslim 13.4%, Christian 2.3%, Sikh 1.9%, other 1.8%, unspecified 0.1% (2001 census)

Languages: English enjoys associate status but is the most important language for national, political, and commercial communication; Hindi is the national language and primary tongue of 30% of the people; there are 14 other official languages: Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Malayalam, Kannada, Oriya, Punjabi, Assamese, Kashmiri, Sindhi, and Sanskrit; Hindustani is a popular variant of Hindi/Urdu spoken widely throughout northern India but is not an official language

Administrative Break–up: 28 states and 7 union territories

Executive Heads: President A.P.J. Abdul KALAM (since 26 July 2002); Vice President Bhairon Singh SHEKHAWAT (since 19 August 2002)

Head of government: Prime Minister Manmohan SINGH (since May 2004)

Economic Overview: India's diverse economy encompasses traditional village farming, modern agriculture, handicrafts, a wide range of modern industries, and a multitude of services. Services are the major source of economic growth, though two–thirds of the workforce is in agriculture. The UPA government has committed to furthering economic reforms and developing basic infrastructure to improve the lives of the rural poor and boost economic performance. Government controls on foreign trade and investment have been reduced in some areas, but high tariffs (averaging 20% in 2004) and limits on foreign direct investment are still in place. The government has indicated it will do more to liberalize investment in civil aviation, telecom, and insurance sectors in the near term. Privatization of government–owned industries has proceeded slowly, and continues to generate political debate; continued social, political, and economic rigidities hold back needed initiatives. The economy has posted an excellent average growth rate of 6.8% since 1994, reducing poverty by about 10 percentage points. India is capitalizing on its large numbers of well–educated people skilled in the English language to become a major exporter of software services and software workers. Despite strong growth, the World Bank and others worry about the combined state and federal budget deficit, running at approximately 9% of GDP. The huge and growing population is the fundamental social, economic, and environmental problem. In late December 2004, a major tsunami took at least 60,000 lives in India, caused massive destruction of property, and severely affected the fishing fleet.

GDP: purchasing power parity – $3.319 trillion (2004 est.)

Important Years for India, since independence

  1. 992: India's worst financial scandal, involving state–owned commercial banks, leads to a major slump on the Bombay stock market.

Sectarian violence erupts after Hindu extremists level the 16th century Babri mosque at Ayodhya on Dec. 6. The violence is the worst seen since Partition. The government's offer to build a mosque and a Hindu temple at the site fails to appease both sides.

  1. 993: Hundreds are killed when bombs go off in Bombay public buildings. Four days later, a bomb ignites in Calcutta. Pakistan denies complicity.
  2. 995: The World Bank allocates a $980 million loan, its largest ever, to aid Indian bank reforms.

Vision India, 2025 (From an Ordinary Person's Point of View)

  1. ) Ensure dignity, Self–Respect and Pride for each individual, irrespective of age, gender, region or religion.
  2. ) Drinking Water, Food, Cloth, Shelter and education for all.
  3. ) World Class infrastructure: roads, airports and railways.
  4. ) Every year there is a loss of billions of rupees due to flood; only solution is «Unification» of all rivers.
  5. ) Only one caste (Brotherhood) and one religion (Humanity), across the length and breadth of the country.
  6. ) No «reservation„, no subsidiary, no “special privilege» and no discount, on the basis of Region, Religion, Community, Profession and Community.
  7. ) Minimum education (Graduate), Minimum Administrative Experience (7–10 yrs) and retirement age (67 yrs) for all politicians. Also, annual appraisal system for all ministers.

(These are the few points, I am able to pen down; however I have not mentioned anything about security and foreign policy…because as an ordinary person above mentioned things are of more importance than anything else)

India in 21st Century

Everyone recognizes that the twenty–first century is the Century of Knowledge. Nations, which have mastered the production of knowledge, its dissemination, its conversion into wealth and social good and its protection have assumed a leadership position in the world today. But it must be recognized that knowledge without innovation is of no value. It is through the process of innovation alone that new knowledge can be created. It is innovation, which converts knowledge into wealth and social good.

India was a leader in innovation several centuries ago. In fact, our innovations were diverse and pioneering. They included

  1. Remarkable town planning,
  2. The use of standardized burnt bricks for dwelling houses
  3. Interlinked drainage systems
  4. Wheel–turned ceramics and solid–wheeled carts.
  5. The dockyard at Lothal in Gujarat is regarded as the largest maritime structure ever built by a bronze–age community.
  6. The discovery of zero and the decimal place value system by Indians dates back to the Vedic period.
  7. Our pioneering work in algebra, trigonometry and geometry was truly outstanding.
  8. Indian innovations in medicine, especially in Ayurveda, not only aimed at the cure of diseases but, more importantly, on the preservation of health.
  9. The innovations in surgery included pioneering efforts in laprotomy, lithotomy and plastic surgery.
  10. 0. The iron pillar at Delhi, which testifies to the achievements in metallurgy some 1500 years ago, is truly inspirational even today.

Indian civilization was characterized by scientific thought, capabilities and techniques at levels far more advanced than others.

In spite of this great heritage and record of accomplishments, why did India fall behind in the ensuing centuries? When the scientific and industrial revolutions took place in the West a few hundred years ago, there was a period of stagnation in India. The lack of development over this period was a result of a hierarchical approach, irrational subjective thinking, and build up of superstitions and superficial ritualism. We have lost the leadership position. This cannot continue into the twenty–first century. We must regain this position with determined action.

Our confidence in building the new innovative India of our dreams stems from our major successes in the arena of many technological innovations that have made such a difference to the nation. Some prominent examples include

the blue (space), green (agriculture), white (milk) and gray (software) revolutions. Let us just take one example.

  1. The Indian space program, for example, has designed and sent into space a series of satellites that, among other things, comprise the largest domestic communication system in the Asia–Pacific region.
  2. It has also developed a range of launch vehicles, the most recent being a geo–synchronous launch vehicle with an 1800 kg payload. These developments have helped in the application of space technology for national needs in communication, meteorology, broadcasting, and remote sensing. All of this has been achieved in a relatively cost–effective manner. The Indian space programmer's current annual budget is equivalent to US $450 million while NASA's budget, in comparison, is over $15 billion.
  3. Other innovations serving specific Indian needs include C–DOT digital switches, CorDECT cost–effective wireless–local–loop products, the Simputer, which is a low–cost computer and the Param supercomputer.
  4. The last is an example of "denial–driven innovation," illustrating that India has the potential to tackle highly advanced technological issues, given the proper motivation.
