Instantaneous
The word instantaneous is derived from the word instant that means at the moment. Any thing when termed as instantaneous indicated towards something that is occurring at a moment or at that point of time. There are times when we are trying to find out a solution of a problem or a situation, but we are not able to find the solution, inspite of the effort, then suddenly at one point of time, the solution might appear. This is called the eureka moment. This is different from instantaneous solution. We can tell a person has solved something instantly when he or she utilizes the presence of mind and gives the solution of a novel problem on spot. This construct has a correlation with both, creativity as well as intelligence. Apart from this, instantaneous decision are often decision made without proper thought or consideration of the situation. This might therefore lead to a certain kind of catastrophe in future.
