Discovery, Innovation and Invention – Know the difference!

Few definations which I came across-

An invention is a new composition, device, or process. An invention may be derived from a pre-existing model or idea, or it could be independently conceived in which case it may be a radical breakthrough.

Discovery can lead to invention. A specific, tangible application of discovery. What is discovered already existed; what is invented did not exist before. Invention results from creativity applied to discovery.
Discovery can also lead to innovation. Innovation is based on something already existing. Innovation is the novel application of something. It can be an idea, or a tangible thing . . . again, commercial or not. Much of the time innovation is the extension of invention. Innovation is also a product of creative behavior.

If you didnt get any of above sentences, lets make it simple.

Discovery is of something that is already present but not in knowledge of humanity whereas innovation is creation of something which doesn’t exist.

Thus, Invention: Creation of a new item.  Discovery: Find something new that was otherwise already present, but not known to be present. Innovation: This is a change in the thought process for doing something or “new stuff that is made useful”.

All what this topic wonder around is understandability of concepts and creative mind.

Intro to Science, Engineering and Technology

Basics are something which are and has to be concentrated before going on for further studies.   Lets have a look at defintions of Science, Engineering and Technology.


Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal  world by employing formal techniques such as the scientific method.   Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result.  Thus, Engineering = application of knowledge gained via science to solve a problem or meet a need.   Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety. Thus, Technology = utilization of processes and products made via engineering, or the specific processes or products themselves.   Wraping in one line- Engineering is cause and Technology is the effect.  

To me engineering is designing and the structure/function of something… While technology is the usefulliness of that object in an applied world sense like in society….
