(남의 글 인용하는거 별로 안좋아하지만..) ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ It will take you some time to understand what should happen in different circumstances. You will have to solve the equations. Each time you solve the equations, you will learn something about the character of the solutions. To keep these solutions in mind, it will be useful also to study their meaning in terms of field lines and of other concepts. This is the way you will really "understand" the equations. ******>>>>>> That is the difference between mathematics and physics. <<<<<<****** Mathematicians, or people who have very mathematical minds, are often led astray when "studying" physicsbecause they lose sight of the physics. They say: "Look, these differential equations - the Maxwell equations - are all there is to electrodynamics; it is admitted by the physicists that there is nothing which is not contained in the equations. The equations are complicated, but after all they are only mathematical equations and if I understand them mathematically inside out , I will understand the physics inside out." Only it doesn't work that way. *****>>>>>> Mathematicians who study physics with that point of view - and there have been many of them - usually make little contri bution to physics and, in fact, little to mathematics. <<<<<<***** They fail because the actural physical stuations in the real world are so complicated that it is necessary to have a mush broader understanding of the equations. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ * lead astray : 타락 시키다. < Phoenix ( 불새 ) > * 항국가하권 학부과정 물리과 '93 * |
