思维方法是解题的关键,往往思维方法的转换能使人茅塞顿开,突破思维定势,从“山穷水尽”之困境,步入“柳暗花明”之坦途.一、顺与逆顺与逆是相对的,逆向思维即从与常规顺(正)向思维相反的方向思考问题,也即倒过来想一想,它是一种创造性的科学思维方法.在物理学史上,法拉第由“电生磁”逆思“磁生电”,这就是具有划时代意义的电磁感应定律.再如麦克斯韦电磁场理论的基本观点——变化的磁场产生电场,变化的电场也产生磁场等,都是逆向思维的示例.同样,我们在解物理题时,若能适时而巧妙地转换思维方向,往往能出奇制胜,获得解题的成功.
The method of thinking is the key to problem solving. Often, the transformation of thinking methods can make people feel at ease, break through the mindset, and go from the dilemma of “extremely diligent” to the candid path of “willow blossoms”. First, Shun and reverse are opposite, and vice versa. Reverse thinking is to think in the opposite direction from normal (orthodox) thinking, that is, to think about it in reverse. It is a creative method of scientific thinking. In the history of physics, Faraday’s thought was reversed by “electromagnetic magnetic resonance.” “Magnetism,” this is the epoch-making law of electromagnetic induction. Another example is Maxwell’s basic point of view of electromagnetic field theory - changing magnetic fields to generate electric fields, changing electric fields to generate magnetic fields, etc. are all examples of reverse thinking. Similarly, we In solving physical problems, if you can timely and cleverly change the direction of thinking, you can often surprise and win the success of problem solving.
