Quote of the day by Carl Sagan : Whether ordering groceries with a smartphone, consulting a doctor through a video call, or using GPS to navigate unfamiliar roads, most people interact with science and technology countless times each day. These innovations have transformed the way the world works, making communication faster, healthcare more advanced, and information more accessible than ever before. Yet the convenience of modern life often means people rarely stop to consider just how deeply civilization depends on scientific knowledge and technological systems.
