Earth is approximately 4.6 billion years old and according to scientists, modern humans did not exist until approximately 200,000 years ago. During this brief “flash-in-the-pan” of existence, they have managed to dominate the Earth in a way that no species has ever done before. This is due to the fact that as the human race expands, it demands an ever-growing amount of fuel, water, land, food, shelter, technology, and the energy necessary to produce, deliver, and operate these goods and services. Recycling not only reduces the burden that modern society places on the planet when population numbers grow, but also provides many benefits, such as: reducing or eliminating municipal, industrial and commercial waste; reducing litter; reducing energy consumption by limiting the need for mining, transporting, and converting of raw materials into goods; limiting pollution via lower energy consumption, less waste, reduced emissions, and the conservation of precious, natural resources; and stimulating the economy with new jobs, increased savings, and higher profit margins for commercial, industrial, and agricultural production. All forms of production require large amounts of electricity and the mining of raw materials from the Earth for new products and services.
In 3500 people began smelting together tin and copper to create a new more resilient metal, Bronze. Though this is barely chemistry these early roots of understanding purification, melting, and bonding of metals pave the way of understand we have today.

Stanislao Cannizzaro began to practice Avogadro’s theory in front of groups of people and stated alkali metals and the alkaline earth metals are two different formulas so anomalies that occur when treating them as one would cease. William Crooke was credited with the cathode ray which helped us to understand and actually see chemistry.

In fact, the Analytical Engine required so much power and would have been so much more complex than the manufacturing methods of the time, it could never be built. No more than twenty years after Babbage¹s death, Herman Hollerith designed an electromechanical machine that used punched cards to tabulate the 1890 U.S. Census. His tabulation machine was so successful, he formed IBM to supply them. (Constable 11) The computers of those times worked with gears and mechanical computation. Unlike today¹s chip computers, the first computers were non-programmable, electromechnical machines.
As the earliest extinct human relatives to become known to science, the Homo neanderthalensis have snatched a relatively iconic influence in human evolutionary investigations. A significance that has been enormously reinforced by the substantial behavioral and fossil record that has expanded since the original Feldhofer Cave skullcap and partial skeleton were unexpectedly uncovered in 1856, by miners working in Germany’s Neander Valley (Tattersall & Jeffrey 1999: 7117-7119). ‘The Neanderthals’ is the informal classification of a particular group of large-brained hominids whom inhabited Europe and Western Asia between 130,000 to around 35,000 years ago. Complementary human populations lived at the same time in Africa and Asia. The Neanderthals were a highly successful race for a substantial period of time, but this situation chang... ... middle of paper ... ...IV burials are known to have had some 'traditional' medical uses, even among comparatively recent 'modern' populations.
Origins of the Watch making Industry The production of watches was a major industry of Great Britain for hundreds of years. Watch making originated in Europe in the early 16th century, when coiled springs were first used to power clocks. Clocks were powered by weights originally, and therefore remained stationary. The springs meant that clocks could be moved for the first time, and soon, German clockmakers started to make very small clocks, which are considered as the earliest watches made. Watch making was the most advanced line of the clock making industry, which developed when Blacksmiths started introducing their skills with metal to clock making.
(N/A,N/a, p1) The Bronze age starts about 2700BC when bronze is discovered. 2400BC in Babylonia the first calculator the abacus is invented. (N/A,N/a, p1) The Iron age starts about 1200BC ends around 587Bc and in this period the use of iron was used to make tools and weapons. (N/A/N/A) 350BC is the start of mechanical gearing like the pulley, lever and screw developed by the Greeks and/or the Egyptians. 300BC the binary number system is invented by Pingala.
Engineers have shaped our world as we know it. There are many different kinds of engineers from chemical, mechanical, textile, civil, agricultural and structural engineers. Our civilization would be as advanced as the Stone Age without these people. This career demands a wide education of math and science. It is an ever-changing career with new advances in materials and the way products are produced.
In today’s society, it’s nearly impossible to open a newspaper, fire up a computer, or hold a conversation that isn’t someway related to energy. Since the beginning of the industrial revolution over a century and a half ago, nothing has been more pivotal to mankind’s rise to power as the apex species of planet earth. Had our ancestors not discovered the potential of using million year old plant and animal remains to create combustible power, the world would look very different. There is no denying that energy production is one of, if not, the most important developments in human history. After a hundred and fifty years of recklessly burning oil and coal, we find ourselves having to deal with the literal mess unforeseen by our industrious forefathers.
And is there any other kind of evidence that might shed a bit of light on how people lived in those times? It is generally acknowledged that starting with our ancestor Homo erectus, humans began to use their hands to make tools (Ponting, 18). This knowledge is based on dating techniques of archaeological findings such as skeletons and early tools, and the rough estimate of the appearance of this tool-using human is around 2 million years ago. In case it is not obvious, that is a very long time. Even in the last 4000 years, the amount of change that human culture and society has undergone is enormous, and at least that much is historically documented by at least some cultures in varying intervals.
