On Why-Questions in Physics
نویسنده
چکیده
In natural sciences, the most interesting and relevant questions are the socalled why-questions. What is a why-question? A why-question is nothing else than a question in the form “Why P?” (or “Why is P true?”) where P is an arbitrary statement. There are several different approaches to why-questions and explanations in the literature, see, for example, [5], [6], [7], [15]. However, most of the literature deals with why-questions about particular events, such as “Why did Adam eat the apple?”. Even the best known theory of explanation, Hempel’s covering law model, is designed for explaining particular events. Here we only deal with purely theoretical why-questions about general phenomena of physics, for instance “Why can no observer move faster than light?” or “Why are Kepler’s laws valid?”. Here we are not going to develop a whole new theory of why-questions in physics. We will just touch upon some ideas and examples relevant to our subject.

متن کاملThe Effect of Teaching History of Physics on Student-Teachers’ Understanding of the Process of Model Construction in Physics
To improve student teachers’ understanding of the process of model construction in Physics, it was hypothesized that teaching the history of Physics may be of help. To test this hypothesis, two groups of senior year female student-teachers in Teaching of Physics at one of the campuses of Farhangian University in Tehran were chosen: One group had passed a course on the history of Physics, while ...
متن کاملBeating the Standard Model *
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersy...
