Dating Back To Science In Olden Days

scienceIt was the invention of the Electric Bulb. This bulb is still in use today even after more than hundreds of years in its original form without much change. Edison worked hard on this invention that, he tried hundreds and hundreds of filaments before he came up with the tungsten filament. As the filament has to be stable even under constant temperature of the Celsius of thousands of degrees, the problem of finding the right filament was a particularly tedious job. After all, the thirst to know is what separates us from other animals! Teaching science to kid will ensure our kid grow as a intelligent one and also create interest in science. Science still continues to be the most fascinating field of mankind and keeps opening doors for the human civilization to grow and prosper.

If everything that is happening today can be based on one single word, then it must definitely be Science. The modern form of Science is the technology. Chemistry, which involves the study of various chemicals and substances present around the globe. Physics is the study of all the physical laws and their meanings. Science today comprises of various fields such as Biology, pertaining to the study of plants and animals. The History of science can be dated back to as far as the B.C or Before Christ period, where there existed great philosophers like Aristotle, Theophrastus and others. Basically, Science means knowledge or to know, derived from Latin word ‘scientia’. Mathematics, a particularly unique branch of science is where various equations and number systems are considered.

An example of how great discoveries happen by accident was illustrated by Sir Isaac Newton as he thought of the law of gravity when an apple fell on his head when he was sitting under an apple tree. One of the greatest ever scientific discoveries which form the basis of the world we live in today came from the man called Thomas Alva Edison. Einstein was awarded the Nobel Prize in Physics. Einstein is considered one of the greatest scientists of all time and he was the man of the 20th century with the publications of several of his papers on the theory of relativity, wave-particle duality and several other physics breakthroughs which were accepted only a little later because of the apprehensions of all the scientists of that time to digest several new concepts.

The major part of the ancient science period consisted of many personalities from Greece. This trend slowly started subsiding and the concept of science started spreading. It was considered to be the temple of knowledge. Many countries like India also had its fair share of philosophers and scientific inventions through the form of Aryabhatta and others. The most greatest of scientific discoveries have come up in this period and includes the discovery of the law of gravity by Sir Isaac Newton, Theory of relativity by Albert Einstein and the invention of the electric bulb by Thomas Alva Edison. After the sixteenth century came the scientific revolution and with it started the creation of the modern science. But, this was not advocated widely as the means of communication between the countries were not established.

The first Neanderthal fossil was identified in 1856 in the Germany’s Neander Valley (although an earlier 1829 find was subsequently recognized as belonging to Neanderthal). But how do we know what’s in our DNA – or for that matter, where it came from? Not much is known about the Denisovans – except, of course, for their entire genome, which was sequenced from a single pinky bone discovered in a Siberian cave. They were found throughout Europe, where they apparently interbred with humans regularly. People with ancestry in these areas are likely to carry both Denisovan and Neanderthal DNA. Scientists do have evidence that the Denisovans occupied much of the area that is now east Asia, Siberia, Indonesia and New Guinea. First found in 2008, these hominins were also contemporaries of early modern humans, disappearing sometime between 30,000 and 15,000 years ago. Today, most people of European descent have some Neanderthal genes. The Denisovans are a less well-recorded group compared to Neanderthals.
