Research in Science, Engineering  and Technology

     Research is the use of appropriate methods in attempting to discover new knowledge or to develop new applications of existing knowledge or to explore relationships between ideas or events. Scientific discoveries, technical/ technological (1) achievements and scholarly publications are all fruits of research.            Every discipline develops tools and technology/techniques (2) appropriate to its subject mater, but whether undertaken by a scholar, technician/technologist (3) or a scientist, research always involves three basic steps: the formulation of the problem, the collection of relevant information and a concerted attempt to discover a solution or otherwise resolve the problem in a manner dictated by the available evidence.

   In the field of science and technology/techniques (4) fundamental (or properly scientific) research aims at enlarging man’s understanding of observable phenomena; the search is for general explanatory principles. Unlike applied or technological research fundamental research is not explicitly directed to the solution of a practical problem, although its results may, and usually do, suggest new technical /technological (5) possibilities. Knowledge of the atomic structure is a goal of fundamental research; possible applications of this knowledge − nuclear power plants and weapons − demand technological research and development. In practice, however, the distinction is less clear-cut: accidental scientific discoveries are often done by research workers pursuing a practical goal in industry and engineering.

Newlands and Mendeleyev

  In March 1866, an English sugar refiner and amateur chemist named John Newlands presented a paper to the Chemical Society with his own idea for bringing order to the elements. He … (1) that when elements were arranged in order of increasing atomic weight, every eighth element was … (2) – or had properties similar to the first element in the group. Elements, he … (3), were multiples of 8, like notes in an octave. He therefore …(4) his system the ‘Law of Octaves’.

Perhaps it was the manner of his presentation, or the fact that he was an amateur, but sadly for Newlands, his idea was (5) with general derision and mockery. One chemist sarcastically commented that he might just as easily have … (6) the elements alphabetically – implying that his system was based on coincidence. His system had its faults, but given time and encouragement he could have (7)  them out. However, he was so disheartened by his reception that he gave up the idea and … (8) from chemistry for good.n 1867, as he … (9) on his Principles of Chemistry, Mendeleyev was unaware of the efforts of Newlands. He simply was trying to solve the    D.I.Mendeleyev       problem with the structure of his book. He … (10) if there might be a relationship between the atomic weights and the properties of elements. He … (11) ordering them by atomic weights in groups of seven, and began to notice a pattern; he saw that the properties … (12) themselves periodically, which was how the Periodic Table got its name. In 1869, it was formally … (13) to the Russian Chemical Society.

In 1870, Julius Lothar Meyer (1830-1895), a German chemist, who independently  from Mendeleev drew up the periodic table, … (14) his version, showing the periodicity of chemical properties.
