科学 (Science) is the systematic study of the natural world through observation and experimentation. It aims to understand how things work, from the smallest particles to the vast universe. Scientists use the scientific method, which involves forming hypotheses, conducting experiments, and analyzing data to draw conclusions. 科学 encompasses various fields, including 物理学 (Physics), 化学 (Chemistry), and 生物学 (Biology). Each field focuses on different aspects of the natural world, such as the laws of motion, chemical reactions, and living organisms. Through scientific research, we gain knowledge that can lead to technological advancements and improve our quality of life.
