Thinking outside the box (also thinking out of the box [1] [2] or thinking beyond the box and, especially in Australia, thinking outside the square [3]) is a idiom that means to think differently, unconventionally, or from a new perspective. The phrase also often refers to novel or creative thinking.
“Make every effort to change things you do not like. If you cannot make a change, change the way you have been thinking. You might find a new solution.”
Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business and technical fields.
A problem whose solution requires a great number of people to change their mindsets and behavior is likely to be a wicked problem. Therefore, many standard examples of wicked problems come from the areas of public planning and policy.
Houston, we have a problem" is popularly quoted as a phrase spoken during Apollo 13, a NASA mission in the Apollo space program and the third meant to land on the Moon.
Creative problem solving (CPS) is a way of using creativity to develop new ideas and solutions to problems. The process is based on separating divergent and convergent thinking styles, so that one can focus their mind on creating at the first stage, and then evaluating at the second stage.
Poincaré and the Three-Body Problem is a monograph in the history of mathematics on the work of Henri Poincaré on the three-body problem in celestial mechanics.
It is possible to use trial and error to find all solutions or the best solution, when a testably finite number of possible solutions exist. To find all solutions, one simply makes a note and continues, rather than ending the process, when a solution is found, until all solutions have been tried.
Hilbert's problems ranged greatly in topic and precision. Some of them, like the 3rd problem, which was the first to be solved, or the 8th problem (the Riemann hypothesis ), which still remains unresolved, were presented precisely enough to enable a clear affirmative or negative answer.
This article is a list of notable unsolved problems in computer science. A problem in computer science is considered unsolved when no solution is known, or when experts in the field disagree about proposed solutions.
