Science

Science is the methodical investigation of the natural world and the knowledge it yields. It entails the study of phenomena by observation, identification, description, experimental inquiry, and theoretical justification. Physics, chemistry, biology, Earth science, and astronomy are just a few of the many subfields of science, each of which focuses on a different aspect of the natural world.

Understanding the natural world in its current state, as opposed to how we might prefer it to be, is the aim of science. To achieve this, scientists apply the scientific method, which is a methodical approach for looking into events and learning new information. Making observations, developing hypotheses to explain those observations, and then putting those hypotheses to the test through observation and experimentation are all parts of the scientific method.

Scientific research has produced a wealth of significant discoveries and technical advancements that have greatly enhanced our quality of life. Many of the problems facing humanity, like climate change, disease, and the security of food and water, can only be solved with the help of science.

science in 20th century:

The 20th century saw a great deal of scientific advancement and discovery. Among the significant advancements in science at this time are:

• DNA, which contains the genetic instructions for all living things, was first discovered to have a double helix shape by James Watson and Francis Crick in 1953. This finding transformed how we understand genetics and has profound ramifications for industries like agriculture and health.
• The advent of quantum mechanics: The early 20th century saw the advent of quantum mechanics, which describes the behaviour of subatomic particles. This theory has had a significant influence on our comprehension of the nature of matter and energy.
• The theory of relativity: Einstein's theory of relativity, which explains the connection between n  space and time, was first published in 1905 and has had a significant influence on how we perceive the cosmos.

• Antibiotic discovery and development: The 20th century saw the discovery and development of antibiotics, which allowed for the treatment of formerly fatal infections.
• The 20th century saw advances in space travel and solar system exploration, including manned expeditions to the Moon and the founding of permanent human settlements on other planets.

These are just a few of the numerous important scientific breakthroughs that occurred in the 20th century. Science has made and will continue to make significant contributions to our knowledge of the world and our capacity to address issues that face humanity.
