In government exams like SSC, Banking, Railways, etc we find many questions from the General Science section. This is a very broad section and sometimes questions are very factual. we will cover the General Science section comprehensively so that students can learn and get most of the questions correct in this section. In this article, we will provide a complete list of Scientific instruments and their Use.
Scientific Instruments: An introduction
- The history of the use and development of this tool helps to show that science is not just a theoretical endeavour, but also activity based on an instrumental base, which is a cocktail of tools and techniques, embedded in a social environment within a community by practitioners.
- The eudiometer was one of the elements in this mix that held a whole community of researchers together, even when they disagreed on the meaning and proper use of the thing.
- The definition of a scientific instrument has varied according to usage, laws, and historical period. Before the mid-19th century, these tools were referred to as “natural philosophical” or “philosophical” apparatus and instruments, and older tools from ancient to medieval times (such as the astrolabe and grandfather clock) defy a more modern definition. of “a tool designed to study nature qualitatively or quantitatively.
- Scientific instruments were made by instrument makers near a centre of learning or research, such as a university or research laboratory. Instrument makers would design, build, and refine instruments for specific purposes, but when demand was sufficient, a tool would go into production as a commercial product.
- The demand for improved analysis of war products such as drugs, fuel, and weapons-grade agents led to new heights in instrumentation. Today, the instruments used in scientific endeavours are changing rapidly, particularly analytical instruments, and connections to computers and data management systems are becoming more necessary.
