Science and technology, while often closely related, are two distinct subjects: Science, a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about nature and the universe.
Science: the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -loggia) is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.
Technology: the application of scientific knowledge for practical purposes, especially in industry.
In its purest sense, “invention“ can be defined as the creation of a product or introduction of a process for the first time. “Innovation,” on the other hand, occurs if someone improves on or makes a significant contribution to an existing product, process or service.
