Science uncovers principles of nature through observation, experimentation, and theory to develop models and extend human understanding. Invention applies scientific discoveries to produce useful effects, devices, and processes. Engineering makes inventions practical for manufacture and widespread use through efficient and cost-effective designs that consider safety, durability, and mass production.
