苏州府的初冬依旧妩媚，薄雾就像是炊烟铺在河面上，然后小船若隐若现。龙腾小说ltxsba.com
“力的方向能改变物体的运动轨迹，你们看。”
船舱里，高景琰轻轻推动茶杯，说道：“我这里从侧面给了茶杯一个力，然后茶杯就克服了重力和摩擦力，向着力的方向滑动。”
一群年轻人正在边上看着，有人甚至在记录。
“这里出现了两个概念。”
高景琰解释道：“茶杯有重量，滑动的时候实际上是和桌面产生了摩擦力，当然，这也是阻力的一种，我说散一些吧，比如说咱们水车，若是轴和套之间能尽量的润滑，那么是不是阻力减少了？运转起来更加的轻便。”
高景琰随即把茶杯推到比较光滑的那一处，说道：“你们看，在光滑的地方，移动茶杯就能省力，所以力的三要素大家要记牢，不但要记牢，而且还要从生活中去观察，观察到力在其中起到的作用。”
“至于摩擦力，这个更是无处不在，大家把手放脸上搓动，手与脸之间就产生了摩擦力，用力搓动，摩擦会产生热量……”
高景琰看到边上的师弟曾光在整理书籍，就说道：“至于摩擦力，这个让曾光给你们说说，记住了，这些都是在我们的身边无时不刻不在发生的奇妙现象，但它并不神秘，只是以前没人去总结而已。”
说完高景琰就出了船舱，随后船主，也是科学的狂热爱好者王辅也跟了出来。
“景琰兄，这些都是贫家子弟，出来一趟不容易，所以还是尽量教，多教些。”
高景琰是富家子弟，喜欢科学后，每次书院的学生来授课大多是在他家，而且食宿，包括那些赶来学习的学生的食宿都是他家在开销。
前方雾气弥漫，就像是此时的科学，前途迷茫。
“山长对科学的传播深信不疑，他说过……”
高景琰面露景仰之色，说道：“山长说科学是自然之学，不高大，不形而上，学了就能知道道理，切身相关的道理。而且还能用，学以致用，这是科学的最大优点，所以我会尽力，让科学在南方播下更多的种子。”
“这次山长亲自安排我们出来，这就是正式开始了，台铮，你学了这几年也差不多了，咱们一起走下去，山长在看着咱们，以后殿下也会看着咱们。”
台铮这个字让王辅有些汗然，这是他老爹，一位渴望家中出高官的老头的手笔。
“景琰兄，自从学了科学之后，小弟就再也看不下那些书了，若非家父开明，小弟肯定会离家出走，到书院去就读，所以你放心，科学……小弟还想着哪天能成为……那种能改变世界的人。”
高景琰笑道：“你以为我不知道吗？当初你可是绝食了好几日，你母亲闹了许久，伯父才改口的。”
王辅汗颜，说道：“我喜欢科学，喜欢那种知道我走一步是用了什么力的感觉。”
高景琰笑道：“谁都喜欢这种感觉，儒学好，也要学，只是偏重不同，这是山长说的。儒学铸就了底蕴和民族气度，而科学会让国强，给那个底蕴和气度镀上一层强硬和自信。”
“要分清主次，分不清，观念混淆，以后还会有风波，那些学生会起争执。”
其实家中已经给高景琰找了生计，甚至金陵的几个衙门都说可以敞开接受书院的学生，可却无一人去，因为大家都知道，自己是播撒种子的人。
“船来！”
这时对面一声喊，这边的船马上靠边。
雾气被破开，一艘船缓缓驶过来。
“……所谓齐其家在修其身者……”
船舱里传来了一个稚嫩的声音，船夫在船尾摇撸，雾气下如仙境般的让人陷入空灵之境。
“……增加压力可以增大摩擦力……”
“……之其所贱恶而辟焉，之其所畏敬而辟焉……”
“……还可以让物体的表面粗糙些，这样也可以增强摩擦力……”
