Science and Technology

Science and Technology is a vast and dynamic field that encompasses the systematic study of the natural world and the application of knowledge for practical purposes. 

1. Science:
   
   • Science is the pursuit of knowledge about the natural world through observation, experimentation, and theoretical explanation. It is divided into various disciplines like Physics, Chemistry, Biology, Earth Science, and more.
   • The scientific method involves making observations, forming hypotheses, conducting experiments, and drawing conclusions based on data.
   • The goal of science is to understand the underlying principles governing the universe, from the behavior of subatomic particles to the vastness of space.

1. Technology:
   
   • Technology refers to the practical application of scientific knowledge to solve problems or create tools that make life easier. It includes everything from simple tools like the wheel to complex systems like computers, medical devices, and space exploration equipment.
   • Technology evolves rapidly, and innovations in one field often drive advancements in others (e.g., developments in material science leading to better electronics).

Key Areas of Focus:

1. Scientific Research:
   
   • Ongoing research in various fields of science, such as biotechnology, quantum computing, artificial intelligence, and nanotechnology, plays a crucial role in shaping the future.
   • New discoveries lead to advancements in medicine, energy, environmental protection, and other critical areas.

1. Technological Innovation:
