Science is 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. History, on the other hand, is the study of past events and societies. It examines how people lived, what they believed, and how they interacted with one another. Important topics in history include ancient civilizations, wars, and cultural movements, which help us understand the development of human societies over time.
