{{Color-box|11|Welcome to the Science Portal|Science, as a body of knowledge as we know it today, is remarkably young, not more than a few hundred years old. And what we know also as science largely relates to the facts and explanations of everyday life. There is a need to examine what constitutes science as a process, the discipline of doing science. What are those elements of study and practice that distinguish science as an endeavour? What are the social dynamics that influence the practice of science? What are the limits of science itself? These are questions that have to be considered by a student of science. Science is also often understood as learning science as a subject and this involves the teaching and learning science and the pedagogy that must be adopted to develop a scientific bent of mind and to prepare the learner for doing science. This is a portal for students and teachers to understand and share resources on both these areas. }}

The student appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbitrator to decide the case.
The arbitrator judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to show a minimal familiarity with the basic principles of Physics.
