Science is the study of the physical and natural world through observation and experimentation. It is typically divided into natural science, physical science, and biological science. Natural science deals with matter, energy, and their interactions, while physical science studies non-living systems. Biological science involves the study of living organisms, including their structure, function, development, and evolution. Some benefits of science include helping humans gain knowledge, assisting those with disabilities, making travel more efficient, increasing agricultural production through fertilizers and new farming methods, and bringing electricity which has provided great services.
