Science involves the systematic study of the natural world through observation and experimentation. It seeks to understand how things work, from the smallest particles to the vast universe. Key fields include biology, chemistry, and physics, each contributing to our knowledge of life, matter, and energy. Engineering applies scientific principles to design and build solutions to real-world problems. It encompasses various disciplines, such as civil engineering, mechanical engineering, and software engineering. The arts, including visual arts, music, and theater, enhance human experience and creativity, often intersecting with science and engineering to inspire innovation and expression.
