性爱大师影音 他商榷出“天下最佳的学习法”,亦然“史上最不郑重的天才”:别闹了,费曼先生!

  最近总听到有东说念主推选什么“费曼学习法”,出于好奇性爱大师影音,我就去搜索了一下。

  原来,费曼学习法被称为“天下上最佳的学习法”,轻佻来说,等于以教的方法,通过我方的谈话,用轻佻的话把学到的事情讲廓清。

  这样一来,你就要确保我方领先领略这些学问,然后以教代学,用“输出”倒逼“输入”,临了进行回来反念念,并好意思满学问的简化和领受。

  年青时的费曼

  这个学习法的创造者,是好意思国闻明物理学家理查德·费曼(Richard Feynman)。

  他1918年缔造于好意思国的一个犹太家庭,幼年时就热衷于不雅察、念念考和作念实验,可爱开顽笑。他接踵就读于麻省理工学院和普林斯顿大学,获表面物理学博士。

  他曾经参加研制原枪弹的曼哈顿霸术,与爱因斯坦等伟大的物理学家和数学家同事;二战后接踵执教于康奈尔大学和加州理工学院,深受学生宽容。

  要是想要了解一下费曼的生平,有一册最值得推选的回忆录《别闹了,费曼先生》(Surely You're Joking, Mr. Feynman)。

  这本回忆录里,记叙了费曼精彩有趣的东说念主生片断,他对物理和我方感风趣的领域的专注执着的追求令东说念主动容,他东说念主生中像老顽童似的开顽笑令东说念主捧腹,他对科学的严谨与真知卓见也令东说念主获益匪浅。

  费曼为什么要商榷物理?是因为奔着某个方针去作念的吗?先来读读下文费曼的郁闷,你当然就会光显,一切皆源于这是他可爱作念的事,与其他无关。

  在康奈尔,我除了备课,还频繁跑到藏书楼去读《一千零整夜》,顺带“观赏”一下从我身边经过的女孩子们。而到了作念商榷的时候,我却无法职责。我有点儿累,我莫得风趣,我作念不了商榷了!那时我以为这种景况抓续了有好几年,但当我回及其去猜度时期时,却发现不可能有那么久。约略现时我也不会以为有那么久,但在那时,那种景况让我以为好像抓续了很长一段时期。

  At Cornell, I'd work on preparing my courses, and I'd go over to the library a lot and read through the Arabian Nights and ogle([ˈəʊɡl] 挑逗地防御;对……送秋波) the girls that would go by. But when it came time to do some research, I couldn't get to work. I was a little tired; I was not interested; I couldn't do research! This went on for what I felt was a few years, but when I go back and calculate the timing, it couldn't have been that long. Perhaps nowadays I wouldn't think it was such a long time, but then, it seemed to go on for a very long time. 

  我等于无法运行入辖下手商榷任何问题:我铭刻有一次我商榷对于伽马射线的某个问题,刚写了一两句我就没法写下去了。这让我服气,因为干戈(编注:指二战)和其他扫数事情(包括我妻子的升天),我依然饱胀意态消沉了。

  I simply couldn't get started on any problem: I remember writing one or two sentences about some problem in gamma rays and then I couldn't go any further. I was convinced that from the war and everything else (the death of my wife) I had simply burned myself out(使……力倦神疲).

  在这时期,我总会收到来自不同地方的邀请,其中有大学也有企业,而且薪水都比我那时的高。每次我收到那样的邀请时,我就会变得更颓靡少许。我会对我方说:“瞧,他们给我开出了这样好的要求,但他们却不知说念我依然困窘不胜了!我虽然弗成领受这些邀请。他们盼望我有所配置,但我却什么也作念不成!我脑子里一派空缺……”

  During this period I would get offers from different places—universities and industry—with salaries higher than my own. And each time I got something like that I would get a little more depressed. I would say to myself, "Look, they're giving me these wonderful offers, but they don't realize that I'm burned out! Of course I can't accept them. They expect me to accomplish something, and I can't accomplish anything! I have no ideas ..."

  然后我有了另一个想法:现时我有点儿气愤物理,但我以前很可爱商榷物理。我以前为什么可爱它呢?我昔日把物理应成游戏。我那每每常是想商榷什么就商榷什么,与这个问题是否对核子物理的发展很要紧绝不联系,而是看它是不是有趣、好玩,能否让我玩起来。上高中时,我看到水龙头里流出来的水越流越细,就会想我是否能弄廓清水流的这种曲线是由什么决定的。我发现这很容易,我正本都没必要这样作念,它对科学的远景又不要紧,而且其他东说念主依然作念过这方面的商榷了。但这些对我莫得任何影响:我照旧会发明创造、游戏科学,只为自娱自乐。

  Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics. Why did I enjoy it? I used to play with it. I used to do whatever I felt like doing—it didn't have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with. When I was in high school, I'd see water running out of a faucet( [ˈfɔːsɪt] 水龙头) growing narrower, and wonder if I could figure out what determines that curve. I found it was rather easy to do. I didn't have to do it; it wasn't important for the future of science; somebody else had already done it. That didn't make any difference: I'd invent things and play with things for my own entertainment. 

  就这样,我有了这个新的心态。既然我依然意态消沉,长期也作念不出任何获利来了,同期我依然有了这份在大学教书的好职责,而且我也很可爱这份职责,那么就像我为了消遣而读《一千零整夜》一样,我筹办把物理也当成游戏来玩,什么时候想玩就玩,无用挂牵任何要紧性之类的问题。

  So I got this new attitude. Now that I am burned out and I'll never accomplish anything, I've got this nice position at the university teaching classes which I rather enjoy, and just  like I  read the Arabian Nights for pleasure, I'm going to play with physics, whenever I want to,  without worrying about any importance whatsoever.

  而后不到一周,我在学校餐厅里时看到,某个干蠢事逗乐的东说念主将一个餐盘抛到空中。当盘子进取飞时我看见它在舞动,我珍重到盘子上红色的康奈尔校徽也在旋转。我看得很廓清,校徽的旋转速率杰出了盘子的舞动速率。

  Within a week I was in the cafeteria and some guy, fooling around(装傻相逗东说念主笑), throws a plate in the air. As the plate went up in the air I saw it wobble( [ˈwɒbl]  摇晃而行), and I noticed the red medallion([məˈdæliən] n. 大勋章,大奖章) of Cornell on the plate going around. It was pretty obvious to me that the medallion went around faster than the wobbling.

  我刚巧闲着没事儿,是以就运行猜度这个转盘的畅通。我发现当角度很小时,校徽的旋转速率是餐盘舞动速率的两倍,即2:1。这是从一个复杂的方程式推算出来的。然后我想:“有莫得更基础一些的要领能让我发现这少许呢,比如从力学或能源学的角度来看,为什么这个比例是2:1呢?”我现时不铭刻我那时是奈何算出来的了,但临了我算出了各质点的畅通,以及扫数的加快度是如何相互均衡使得转速与摆速比达到2:1的。 

  文

  I had nothing to do, so I start to figure out the motion([ˈməʊʃn] n. 畅通;出动) of the rotating( [rəʊˈteɪt] vi. 旋转;动弹) plate. I discover that when the angle is very slight, the medallion rotates twice as fast as the wobble rate—two to one. It came out of a complicated equation! Then I thought, "Is there some way I can see in a more fundamental way, by looking at the forces or the dynamics, why it's two to one?"    I don't remember how I did it, but I ultimately worked out what the motion of the mass particles is, and how all the accelerations([əkˌseləˈreɪʃn] n. 【物】加快度) balance to make it come out two to one.

  我还铭刻我跑到汉斯·贝特那边去说:“嘿,汉斯!我发现了些有趣的事情。餐碟是这样旋转的,转速与摆速之比为2:1是因为……”我向他展示那些加快度。他说:“费曼,这很有趣,但有什么风趣吗?你为什么要作念这事儿?”“哈!”我说,“什么风趣也莫得。我商榷这个等于以为好玩长途。”他的反映并莫得让我气馁,我依然下定决心,我要享受物理,可爱作念什么就作念什么。

  文

  I still remember going to Hans Bethe and saying, "Hey, Hans! I noticed something interesting. Here the plate goes around so, and the reason it's two to one is ..." and I showed him the accelerations. He says, "Feynman, that's pretty interesting, but what's the importance of it? Why are you doing it?"    "Hah!" I say. "There's no importance whatsoever. I'm just doing it for the fun of it." His reaction didn't discourage me; I had made up my mind I was going to enjoy physics and do whatever I liked.

  我无间商榷,算出餐盘舞动的那些方程式。然后我又念念考电子轨说念在相对论框架里是如何运行畅通的,接下来是电能源学里的狄拉克方程,再接着是量子电能源学。在我刚毅到之前(因为这一切发生在一段很短的时期里),我就依然在“玩”——现实上应该说是在商榷——那些我曾经兴趣、但来到洛斯阿拉莫斯之后就罢手商榷了的相通的老课题:我的那些论题式问题,还有扫数那些很逾期却有趣的事情。

  I went on to work out equations of wobbles. Then I thought about how electron( [ɪˈlektrɒn] n. 【物】电子)orbits start to move in relativity([ˌreləˈtɪvəti] 相对论). Then there's the Dirac Equation( 狄拉克方程,1928年英国物理学家狄拉克建议的一个电子畅通的相对论性量子力学方程)in electrodynamics(电能源学). And then quantum electrodynamics(量子电能源学). And before I knew it (it was a very short time) I was "playing"—working, really—with the same old problem that I loved so much, that I had stopped working on when I went to Los Alamos: my thesis-type problems; all those old-fashioned, wonderful things.

  这绝不深邃。“玩”这些事情很消弱,就像开瓶盖一样,一切坚苦贵重就流了出来。我那时还差点儿试图造反它!我那时作念的事莫得任何风趣可言,但到头来却特地要紧。那些图表和助我赢得诺贝尔奖的通盘商榷都是因为我把时期花消在了阿谁舞动的餐盘上。 

  文

  It was effortless. It was easy to play with these things. It was like uncorking(拔去……塞子;掀开瓶子)a bottle: Everything flowed out effortlessly. I almost tried to resist it! There was no importance to what I was doing, but ultimately there was. The diagrams([ˈdaɪəɡræm] n. 图表;图解。这里指费曼图,是费曼所创立的一种用形象化的要领简单地科罚量子场中多样粒子相互作用的图。)and the whole business that I got the Nobel Prize for came from that piddling around(把时期花在不要紧的事情上)with the wobbling plate.

  提到“物理学家”,只怕许多东说念主起首料到的是深不可测的严肃外在、不吃烟炊火的孤介性格以及两耳不闻窗外事的职责狂。

  然则,诺贝尔物理学奖赢得者理查德·费曼涵养的回忆录《别闹了,费曼先生》却透彻颠覆了东说念主们对物理学家的印象。

  从他的书中,咱们看到的不是一个日日千里浸在实验室里正刚直当的科研职责者,而是一个会解密码锁、会敲饱读、会画画、爱搞开顽笑、令东说念主忍俊不禁的年青东说念主。

  难怪物理学家弗里曼·戴森涵养在康奈尔大学初见费曼时对他的印象是“半是天才,半是滑稽演员”,自后跟着对费曼的了解加深,戴森又把原来的评价修改为“饱胀是天才,饱胀是滑稽演员”。     

  《别闹了,费曼先生》以一个个有趣纯确凿平淡故事告诉咱们这位大物理学家是若何真金不怕火成的。

  童年期间的费曼热衷于创新收音机,却仅仅为了抢先听完播送节目给小伙伴剧透以泄露我方的“断事如神”;上学时他自学三角函数,自创数学标志妥协题要领,还平正防盗铃,以便有东说念主参预时提前报警……

  到了大学时期,他依然乐此不疲地进行着独具费曼特质的开顽笑实验:他用物理学问讥刺餐厅做事员,把手浸在苯里然后燃烧,和别东说念主争论尿液是不是由于地心引力向外排出时竟现场扮演倒立撒尿以示事实胜于雄辩,为了泄露注解同期食用阿司匹林和可乐不会让东说念主我晕而切身实验了数次……

  他的一世似乎充满了乐趣和开顽笑,令东说念主忍俊不禁又倍觉新奇。

  费曼对许多领域都充满了好奇,况兼乐于尝试:他花了一年多的时期商榷密码锁,在原枪弹研发基地那样严实的安保系统下消弱破解密码锁,成为连锁匠都要向他求教的开锁群众;

  他去学习敲弗利吉得拉(一种金属打击乐器),假借艺术家的身份为跳舞配乐公演时还赢得了好评;他跟一又友学画画,最终举办了个东说念主画展,有些作品还卖得了好价格……

  他坦率而又不无赋闲地告诉咱们他的特立独行:在酒吧茅厕里和醉鬼大打入手;在赌城中与做事赌徒商榷赢输机率;当他常去的酒吧以妨碍风化遭到取缔时,他上法庭为之辩白……

  费曼先生等于这样一个好奇心极强而又纯粹而为的东说念主,他一世幽默机智、几近顽童的言行堪与他在表面物理领域的成就王人名。     

  如同在幼年时发明了属于我方的三角函数标志一样,费曼在看待和领略天下方面也有着独到的方法——他靠追赶风趣来提示糊口的地点。

  他可爱在平淡糊口的点滴中,在狂妄的时期、随便的地点,切身施行考证册本上的定理定律,筹商这个天下他感风趣而又未知的领域。

  他的有趣和他的成就都来自于他对天下长期保抓的孩童般的好奇之心,以及不惮违背常理去探索的纯粹而为。群众都预防的他巧合预防,群众不预防的他却可能穷追不舍,因为在他看来,一切都是游戏,都是为了好玩、取乐。

  看到水龙头里流出的水,读高中的他会去猜度水流的曲线;看到出来觅食的蚂蚁,当了涵养的他仍会兴高采烈地商榷蚂蚁的出动道路。费曼满怀好奇探索着天下的奥妙,他享受着这个经由,随心随心。他的资历在很猛进度上颠覆了咱们传统的得胜不雅。

  一直以来,咱们认为伟大的成就往往等同于为了某一特定方针而进行的繁重卓绝的鼓吹,但费曼却告诉咱们,单纯地追求我方的风趣也不错成就伟大的行状。即使在取得一定成就之后,他仍能找回自我,不忘应允。

  正如节选中所述,费曼在资历无法作念商榷甚而运行气愤物理的瓶颈之后光显:莫得必要去忧虑课题对物理学、对东说念主类发展是否要紧,只为了好玩就好。

  在费曼眼中,物理成了游戏,不错什么时候想玩就什么时候玩,不再挂牵这样作念有什么风趣。这是一种摈弃了实用认识、功利认识的魄力,亦然一种开脱灵动、龙飞凤舞的性格。也恰是这样的魄力让他取得了紧要的成就。      

  在费曼身上,天才的气质和滑稽演员般的风趣绝妙地王人集起来,成就了他清秀多彩的东说念主生。他以特立独行的方法享受着糊口,以孩童的眼睛来探索着天下的奥秘,是以天下将遗迹赠还给他。

  其实,摈弃功利心和实用认识,单纯的可爱和景仰亦然一种当作的原理和得胜的路子,而且这样的嗅觉必当愈加高明,难说念不是吗?
