“Most people want to feel issues are simple rather than complex, want to have their prejudices confirmed, want to feel that they ‘belong’ with the implications that others do not, and need to pinpoint an enemy to blame for their frustrations.” J.A.C. Brown Techniques of Persuasion.
“大部分人都希望面对简单的东西,而不是复杂的东西,希望能让自己的成见得到证实,希望看到自己‘适合于’别人不适用的推论,还需要把自己的失意归咎于某个敌人才行。” J.A.C. Brown 的 Techniques of Persuasion 一书如是说。
“The Untrained mind will usually take the path of least resistance.” Robert J. Gula Nonsense
“未经训练的头脑常常选择那条阻碍最小的路径。”Robert J. Gula 的 Nonsense 一书如是说。
“The tendency to avoid challenge is so omnipresent in human beings that it can properly be considered a characteristic of human nature. But calling it natural does not mean it is essential or beneficial or unchangeable behavior. It is also natural to defecate in our pants and never brush our teeth. Yet we teach ourselves to do the unnatural until the unnatural becomes itself second nature.” M. Scott Peck Road Less Traveled
“逃避挑战的倾向在人类中无所不在,完全可以看作是人的一种天性。但说它是天性并不意味着它就是必须的或有益的或无法改变的行为。把大便拉到裤子上,从来不刷牙,这也是天性。但我们教会了自己去做违反天性的事情,直到这种违反天性的行为变成了自己的第二天性。” M. Scott Peck 的 Road Less Traveled 一书如是说。

等于多少?学生答
,一堂课下了也都没有异议…下课后访问学者耐心教上课老师正确的方法…几个月后访问学者恰好又听到那位老师的课,课堂上还是有学生说
,下课后访问学者就问上课的老师,“我不是告诉过你这样计算不对吗?”老师很无奈,“我知道,可是大家都喜欢这样计算。”
),下半场罚球三罚一中(
),整场就是五罚两中(
吗,看来人家老美课堂是按照NBA的算法。
的形式,我们想能不能有
的等式,或是
的运算规则呢?(就如罚篮的例子)


,假定串联的两个电阻材料(电阻率
相同,横截面积S相同,电阻的区别仅仅反映在程度L上。
,所以有
。更一般的情况是,
。而对于n个相同的电阻串联,等效电阻
,这也可以理解为有限的电阻值是由无限的无限小电阻串联累加的,就如1是由2个1/2、3个1/3、4个1/4…n个1/n串联的。
与
,也可以考虑成
。就是通常的的分数加法运算。
,假定并联的两个电阻材料(电阻率
。所以有
。更一般的情况是,
。
,这样有限的电阻可以看成是无限多个无限大并联而成。比如1是有2个2、3个3…n个n并联。
并联等效电阻,方法为
。再如3和6两个电阻并联,
(并联中3相当于2个6)。由此我们可以给出这样的电阻并联公式
;
,再如某热水器单独烧水一壶水的时间为30分钟,另一热水器单独烧开同一壶水的时间为15分钟,并联两热水器后共同烧水的时间计算可以按照
分钟。具体的可以参考以前的一篇
