The field is not limited to geometry, but its usefulness has been proved in every field of human intelligence. This method of reasoning is called deductive reasoning. The use of this method is to find a solution to a problem using already accepted facts. In general, every detective story is an example of a method of inference. Thus science is one of the biggest detective stories. Conan Dial in his Imagination quoted the famous detective Sherlock Holmes as saying at one place that “from a drop of water one might logically imagine the Atlantic Ocean or Niagara Falls, though he has seen neither the ocean nor the falls.” Only roar is heard. In the same way, life is basically a vast series, with a single glance of which one can understand its entire nature. The science of inference and analysis, like any other art, can be learned only by long study and patience.
Euclid compiled material written by Thales, Pythagoras, Plato, and other Greek and Egyptian scientists. The solution of various problems of geometry is not due to Euclid. Arranging the known facts in such a way that by adding the existing facts, the information of new ideas and their evidence is also available, this is the gift of Euclid. Euclid combined general definitions (axims) with propositions (theorems) that could be proved logically.
Plato knew the importance of geometry. Knowledge of geometry was mandatory for admission to his academy. He said that those who do not know geometry should not be given admission in his institution.
Abraham Lincoln also accepted the importance of geometry. At the age of 40, he studied the works of Euclid. This study was not for the knowledge of mathematics, but for gaining proficiency in reasoning. The study of all branches of science and industry, such as mechanics, acoustics, optics, navigation, nuclear science, biology and medicine, is based on Euclid’s conclusions. And new discoveries of science will also depend on this logic system.
Euclid was a Greek mathematician and teacher from Alexandria. Nothing is known regarding his personal life. Till date, no such documents have been found, which would have given information about Euclid’s date of birth or his place of birth. We only know that he was a teacher of mathematics in the state school of Alexandria and that the number of copies of his book have been sold till date, probably no other book except the Bible has been sold.
Euclid is called the father of geometry, and rightly so. He collected all the known elements of geometry. He organized these generally inconsistent elements developed due to practical needs in a comprehensible, coherent and beautiful method, so that one proof becomes the basis of the next proof. Euclid did all this with the quality that one theorem went on to become the basis of another mathematical proof. And it was proved that what a man cannot do if he uses his power!
Egypt is called ‘the gift of the river’. Much of the fame of ancient Egypt was due to this river. Ninada breaks its banks every year in flood and brings black fertile soil from distant hills. This is the secret of Egyptian agriculture. Floods brought wealth, but many problems also came to the fore. The Nile River changes its course every year. Due to this the boundaries of the land change and become unclear. It is difficult to collect land tax, because the extent of land that is entitled to each person is not fixed. This is essential for tax purposes.
Today, more than two thousand years have passed since this book was written, yet high school students still read it today.
Einstein’s reference is to Euclid’s well-known book called ‘Elements’ (Geometry-Basics). Translate it in every language of the world have paid Its first edition in English came out in 1570. This English translation is based on the Latin translation and the Latin translation is based on the Arabic version of the original Greek. The original Greek book was composed around 300 years before Christ.
The root meaning of the word geometry is – ‘measuring the ground’. Geometry was developed only to measure the land. It seems that the Egyptians did not pay much attention to the theoretical side of geometry. However, for years he was following the same principles and doing his job well. There were also deficiencies in his knowledge of geometry. The uneven land was divided into small triangular pieces. By adding their area, the area of the whole land was calculated. The result was that many small landlords used to pay more amount to the government treasury every year. The helplessness was such that the land surveyors used wrong methods to calculate the area of the land.
The Egyptians used to make right angles without land surveying instruments. We do the same even today while building a playground or laying the foundation of scaffolding on the farm. To make right angles, he used a triangle made of rope. Its sides were 3:4:5 respectively. When this rope was stretched with the help of knots on the sides, then the angle formed between the lengths of 3:4 became a right angle. For this reason the land surveyors of Egypt were called ‘tow pullers’.
When the Greek mathematician Thales heard about these geometrical rules of the Egyptians, he was surprised how their experiment was so accurate. This curiosity proved to be the first step to develop geometry as a science. For the solution of his curiosity, Thales made a rule that to reach any theory / conclusion, only the known facts should be supported and as far as possible, with the help of these, we should move forward in our thinking process. Thales knew that geometry was a practical science, which could be used in navigation and astronomy in the same way as in measuring land or building pyramids. The next step in the development of geometry was taken by Pythagoras and his disciples. He separated geometry from its practical side. He continued to search for logical proofs of geometrical facts. He developed this system in such a way that it is still stable after so much time and its
