The scientific method refers to a process of thought based on integrating previous knowledge, observing, measuring, and logical reasoning.
“If it disagrees with the experiment, it’s wrong. In that simple statement is the key to science.”— Richard Feynman
Hello guys welcome back again in the new video. Hope you all are good, the question What is science fascinated mankind throughout the ages.
Science is the study of how the natural world works. Technology is the application of science to solve problems and to do useful things. However, the everyday world makes no crisp distinction between science and science-based technology, seeing science as both the investigation of the natural world and the development of technology, with the latter aspect being considered far more important. Such an undifferentiated understanding does a disservice both to basic and to applied science.
Everything that happens in the physical world must comply with the scientific principles that govern the world. Therefore, the more we know about these physical principles, the more useful technology we can create, and the more practical problems we can solve. Applied science is nourished by basic science. If this nourishment were to stop, applied science would become a shadow of its former strength. Basic science is driven by pure curiosity. Most modern technological advances that have proved to be economically important sprang from curiosity-driven research. For example, computing is based on abstract mathematical principles. In 1847, George Boole (1815-1864), the first professor of mathematics at University College Cork, built a bridge between mathematics and formal logic through a new form of algebra, known today as Boolean algebra. Boolean algebra now underlies all programming of digital computers, but Boole had no idea of this future use of his invention when he quietly developed it in Cork.
There are many other examples. For example, genetic engineering and modern biotechnology all flow from the curiosity-driven discovery of the structure of DNA in 1953 by Francis Crick and James Watson. The most interesting thing about science is that it’s never finished. Every discovery leads to more questions, new mysteries, to something else that needs explaining. It’s a case of ‘the more we know, the more we know we know nothing at all’
Even within the ‘body of knowledge’ that science has garnered, nothing is ever ‘proven’. While we may have a lot of data to support the theory that yes, gravity does exist or that humans evolved over millions of years, we are constantly refining and reassessing the data. Because of Einstein, gravity today is not what it was for Newton or Laplace. Any new evidence may support this theory but it doesn’t prove it. While we accept certain theories as ‘true’, we do this provisionally. ‘Truth’ today does not guarantee we will not tomorrow find evidence to the contrary. Science is constantly gathering additional evidence concerning known theories … just in case.
Science can help us to understand ourselves and our world, to recognise how it works and where we fit within it. There will always be questions to be answered. What happens after we die? What causes us to dream? What is consciousness? It is this search for answers, humanity’s innate curiosity and drive to know ‘why’, that pushes scientific discovery forward. It’s possible science may one day find the answers, but if not it won’t be for lack of trying.
