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 discuss the importance of scientific instruments.
Importance of Scientific Instruments:
- Scientific instruments vary in size, shape, purpose, complication, and complexity. These include relatively simple laboratory equipment such as scales, rulers, stopwatches, thermometers, etc. Other simple tools developed in the late 20th or early 21st century include the foldscope (an optical microscope), the SCALE (KAS periodic table), the Mas Spec Pen (a pen that detects cancer), and the blood glucose meter, etc. However, some scientific instruments can be quite large and of considerable complexity, such as Particle accelerators or radio telescope antennas.
- micro- and nanoscale technologies are advancing to such an extent that instrument sizes are shifting by the minute, including nanoscale surgical instruments, biological nanobots, and bioelectronics.
- In the age of science and technology, Instruments increasingly rely on computer integration to enhance and simplify control. improve and expand instrument functions, conditions, and parameter settings; and optimization of sampling, collection, resolution, analysis (both in-process and post-process), and data storage and retrieval. Advanced instruments can be connected directly or through middleware as a local area network (LAN) and used as part of an information management application such as a Laboratory Information Management System; be further integrated.
- Instrument connectivity can be further enhanced by using Internet of Things (IoT) technologies, allowing, for example, widely separated labs to connect their instruments to a network managed by a workstation or a mobile device in another location.
