Difference between Science, Engineering & Technology

Science:

• Science is the body of knowledge of the physical and natural worlds
• Science seeks to describe and understand the natural world and its physical properties.
• Science uses varied approaches - scientific methods such as controlled experiments or longitudinal observations studies- to generate knowledge.
• Scientific knowledge can be used to make predictions.
  

Engineering:

• Engineering is  the application of knowledge in order to design and maintain technologies.
• Engineering seeks solutions for societal problems, needs and wants.
• Engineering approaches - for examples, engineering design processes or engineering analyses - to produce and evaluate solutions and technologies.
• Engineering aims to produce the best solutions given resources and constraints.

Technology: 

• Technology is the body of knowledge, systems, processes and artifacts that results from engineering.
• Technology can be used to describe almost anything made by humans to solve a problem or meet a need.
• Technology results from the process of engineering.
• Technologies are anything made by humans to fill a need or desire.
