1. Science as a Human Endeavor
Science is a product of human curiosity and the collective effort to understand, explain, and influence the natural world. Throughout history, humans from diverse cultures have observed nature, asked questions, and developed explanations about how things work.
Scientific knowledge is cumulative. Each new discovery builds upon previous observations, experiments, and theories. For example, the development of modern physics emerged from centuries of work by scientists such as Aristotle, Galileo, Newton, and Einstein. These contributions were shaped not only by individual insight but also by the historical and cultural context of their times.
Science also evolves as new technologies and methods emerge. The invention of the telescope allowed astronomers to observe distant galaxies, which transformed our understanding of the universe. Similarly, advances in DNA sequencing revolutionized biology and medicine.
