Communications technology was able to make huge advances before World War II as more specialized tubes were made for many applications. Radio as the primary form of education and entertainment was soon challenged by television, which was invented in the 1920s but didn’t become widely available until 1947. Bell Laboratories publicly unveiled the television in 1927, and its first forms were electromechanical.

The basic definition of the work an engineer is to apply the principles of science and mathematics to develop economical solutions to technical problems. Put another way, such an appraisal determines whether the pre-requisites of a successful project have been covered and good choices have been made in regard to (i) location, (ii) plant capacity, (iii) raw materials requirements and (iv) other such factors as availability of required professional, technicians and workers. In addition, project costs are estimated and subsequently manufacturing costs are worked out. Adverse environmental impact, if any, is also visualized and efforts are made to reduce it through a better project design incorporating treatment of effluents and noise abatement. Yes, the waves from the cell phones are harmful to our physical body such as our heart, but most of us cannot avoid it. It can affect our heart and internal organs. Recent study tells that even reproductive … Read the rest
