Mathemetics Illuminated

Mathematics Illuminated is a 13-part multimedia learning resource for adult learners and high school teachers in math and other disciplines. The series explores major themes in the field of mathematics, from mankind's earliest study of prime numbers to the cutting edge mathematics used to reveal the shape of the universe. Rather than a series of problems to be solved, mathematics is presented as play we engage in to answer deep questions that are relevant in our world today. Mathematics also provides us with a powerful language for uncovering and describing phenomena in the world around us. The groundbreaking videos, interactive Web exploration, text materials, and group activities included in Mathematics Illuminated reveal the secrets and hidden delights of the ever-evolving world of mathematics.

1. The Primes
The properties and patterns of prime numbers — whole numbers that are divisible only by themselves and one — have been a source of wonder across cultures for thousands of years, and the study of prime numbers is fundamental to mathematics. This unit explores our fascination with primes, culminating in the million-dollar puzzle of the Riemann Hypothesis, a possible description of the pattern behind the primes, and the use of the primes as the foundation of modern cryptography.

VOD2. Combinatorics Counts
Counting is an act of organization, a listing of a collection of things in an orderly fashion. Sometimes it's easy; for instance counting people in a room. But listing all the possible seating arrangements of those people around a circular table is more challenging. This unit looks at combinatorics, the mathematics of counting complicated configurations. In an age in which the organization of bits and bytes of data is of paramount importance — as with the human genome — combinatorics is essential.

VOD3. How Big Is Infinity?
Throughout the ages, the notion of infinity has been a source of mystery and paradox, a philosophical question to ponder. As a mathematical concept, infinity is at the heart of calculus, the notion of irrational numbers — and even measurement. This unit explores how mathematics attempts to understand infinity, including the creative and intriguing work of Georg Cantor, who initiated the study of infinity as a number, and the role of infinity in standardized measurement.

VOD4. Topology's Twists and Turns
Topology, known as "rubber sheet math," is a field of mathematics that concerns those properties of an object that remain the same even when the object is stretched and squashed. In this unit we investigate topology's seminal relationship to network theory, the study of connectedness, and its critical function in understanding the shape of the universe in which we live.

VOD5. Other Dimensions
The conventional notion of dimension consists of three degrees of freedom: length, width, and height, each of which is a quantity that can be measured independently of the others. Many mathematical objects, however, require more — potentially many more — than just three numbers to describe them. This unit explores different aspects of the concept of dimension, what it means to have higher dimensions, and how fractional or "fractal" dimensions may be better for measuring real-world objects such as ferns, mountains, and coastlines.

VOD6. The Beauty of Symmetry
In mathematics, symmetry has more than just a visual or geometric quality. Mathematicians comprehend symmetries as motions — motions whose interactions and overall structure give rise to an important mathematical concept called a "group." This unit explores Group Theory, the mathematical quantification of symmetry, which is key to understanding how to remove structure from (i.e., shuffle) a deck of cards or to fathom structure in a crystal.

VOD7. Making Sense of Randomness
Probability is the mathematical study of randomness, or events in which the outcome is uncertain. This unit examines probability, tracing its evolution from a way to improve chances at the gaming table to modern applications of understanding traffic flow and financial markets.

VOD8. Geometries Beyond Euclid
Our first exposure to geometry is that of Euclid, in which all triangles have 180 degrees. As it turns out, triangles can have more or less than 180 degrees. This unit explores these curved spaces that are at once otherwordly and firmly of this world — and present the key to understanding the human brain.

VOD9. Game Theory
Competition and cooperation can be studied mathematically, an idea that first arose in the analysis of games like chess and checkers, but soon showed its relevance to economics and geopolitical strategy. This unit shows how conflict and strategies can be thought about mathematically, and how doing so can reveal important insights about human and even animal behaviors.

VOD10. Harmonious Math
All sound is the product of airwaves crashing against our eardrums. The mathematical technique for understanding this and other wave phenomena is called Fourier analysis, which allows the disentangling of a complex wave into basic waves called sinusoids, or sine waves. In this unit we discover how Fourier analysis is used in creating electronic music and underpins all digital technology.

VOD11. Connecting with Networks
Connections can be physical, as with bridges, or immaterial, as with friendships. Both types of connections can be understood using the same mathematical framework called network theory, or graph theory, which is a way to abstract and quantify the notion of connectivity. This unit looks at how this branch of mathematics provides insights into extremely complicated networks such as ecosystems.

VOD12. In Sync
Systems of synchronization occur throughout the animate and inanimate world. The regular beating of the human heart, the swaying and near collapse of the Millennium Bridge, the simultaneous flashing of gangs of fireflies in Southeast Asia: these varied phenomena all share the property of spontaneous synchronization. This unit shows how synchronization can be analyzed, studied, and modeled via the mathematics of differential equations, an outgrowth of calculus, and the application of these ideas toward understanding the workings of the heart.

VOD13. The Concepts of Chaos
The flapping of a butterfly's wings over Bermuda causes a rainstorm in Texas. Two sticks start side by side on the surface of a brook, only to follow divergent paths downstream. Both are examples of the phenomenon of chaos, characterized by a widely sensitive dependence of the future on slight changes in a system's initial conditions. This unit explores the mathematics of chaos, which involves the discovery of structure in what initially appears to be randomness, and which imposes limits on predictability.

Video Lecture Series on Annenberg Media

Annenberg Media was formerly known as Annenberg /CPB when it was a project contracted by the Annenberg Foundation located at the Corporation for Public Broadcasting. At the conclusion of the contract with the Annenberg Foundation in 2004, Annenberg/CPB left the CPB and became a part of the Foundation. Shortly after, the name was changed to Annenberg Media.

The mission of Annenberg Media is claimed to advance excellent teaching in American schools through the development and distribution of multimedia resources for teaching and learning. Now, their web site, www.learner.org, is streaming various video programs for public, and it is free.

Bookmarking www.learner.org are highly recommended. Many of its video programs are very previous for many of Chinese students who are looking for opportunities to study abroad in the future, for these video programs can help students build a solid foundation of knowledge for future leaning in USA, as well as in other western countries. Most of the resources are conveying common sense of accumulated human knowledge, and perhaps are most qualified learning material for advanced ESL students.

This is indeed a very useful and generous web site. I began to love it as soon as I watched merely a short part of a video about the prime number. Nearly every aspect of knowledge can be found in the website as the form of video. At the same time, the contents are also from elementary ones to complicated ones( e.g.: in Mathematics Illuminated, you can find videos from easy prime numbers to the concepts of chaos.).

杨佳,一路走好。

已经走了,就没什么可说的了。虽然有腐败的司法,黑暗的政府和心知肚明却必须致人于死地的国家,但是同样还有我们,有那么多支持你,关注你,默默为你祈祷,为你默哀的人们。正义已经无足轻重,因为这个词在政府,在独裁统治中已经失去了本身的含义。
感谢那些试图帮助他的人们,因为是你们捍卫了正义的尊严。但是时间无法回流,人死不能复生,但是我仍想在你被毒液侵蚀之后的身影后面说,杨佳,一路走好。







附:杨佳26日上午在上海被以注射方式执行死刑(新华社报道)

对于受到社会广泛关注的杨佳袭警杀人案,中国最高人民法院经过复核,日前依法作出核准杨佳死刑的裁定。上海市第二中级人民法院按照最高人民法院下达的执行死刑命令,于26日对罪犯杨佳以注射方式执行了死刑。

  最高人民法院经复核确认,被告人杨佳因对2007年10月5日晚在上海市受到闸北公安分局芷江西路派出所民警的依法盘查及公安机关对其投诉的处 理情况不满,经精心预谋和周密准备,于2008年7月1日上午闯入闸北公安分局办公大楼,持刀行凶,致6名民警死亡、2名民警轻伤、1名民警和1名保安员 轻微伤。

  最高人民法院复核该案认为,被告人杨佳为泄私愤而报复杀人,犯罪手段特别残忍,犯罪情节特别恶劣,后果和罪行极其严重,社会危害性极大,应依法 惩处。第一审判决、第二审裁定认定的事实清楚,证据确实、充分,定罪准确,量刑适当,审判程序合法。据此,最高人民法院依法作出核准杨佳死刑的裁定。

  执行死刑前,杨佳同其母亲王静梅进行了会面。

杀吧,不要以正义的名义 08.11.26 (转载)

爱杀就杀吧,可以痛快点,多大点事啊,没有人会在意的,放心大胆的做吧。灭掉个吧生命,既不是第一千一万次,也不是最后一次,当战车碾过年轻人的身体时,你们一个都没犹豫来着。

既然你们早已清楚地知道罪恶不会带来丁点的惩罚,既然谎言是唯一的方式可能延缓死亡,既然在这片荒原上永远长不出正义的草来,那就再没有什么理由可以真正 阻挡住你了。想通过“合法的渠道”与最高人民法院要“事实真相”,谈“公平与正义”,那是与虎谋皮令人耻笑。今天有谁能够说出,国家与贼有何区别,如果说 公检法是婊子,那是对卖身服务行业的污蔑。

你拥有全部的权力和财富,河流山脉,拥有这块土地上可以看得到摸得着一切,一切的光荣和欢乐都属于你,你不会郁闷的。为了百年千年天荒地老的宏图大业的长治久安,痛快地抓,痛快的杀吧,不要再告诉人们你释放了多少西藏人,不要再说分赃大了点,几万个亿就 “一定要有透明的民主程序”。还有谁会相信废话。在这里除了十恶不赦的权力,剩下的皆是傻逼,这是一个关于共和国的完整的版本。

杀吧,不要用正义的名义,那是在羞辱一切。没有一个政权会在意它将会被轻蔑地记住。

杨佳死刑 08.11.25 (转载)

王静梅今天下午七时接待了上海来的徐法官和蒋法官,向王静梅通知了最高人民法院审核杨佳案的结果:维持原判,死刑。

刘晓原:刚才王静荣给我打电话来说你马上给王静梅打电话,我正要给王静梅打电话的时候,王静梅已经给李律师打电话来了,她们说最高法院来了两个法官向他宣布最高法院核准了杨佳死刑。

艾未未:什么时间来的?

我给他打电话时候大约是720左右,她们说刚走没多长时间,是从上海过来的。

为什么是从上海过来的?

上海市高级人民法院受最高人民法院委托来宣读,这个在法律上没有多大问题,法律上这种宣读是可以的。

这个核准不是最高法院来宣布的是上海市高级人民法院来宣读的?

这个宣读法律上是没有问题的。

我知道这个程序是合理。那么原话怎么说呢?就是最高人民法院审核已经核准。

对,就是核准了杨佳的死刑。

那么他们来是什么意思?

就是来通知家属核准了死刑。这个高法是可以委托下级法院来宣读核准意见,在法律上是合法的。

那问题在哪?

问题就是我们过去说过的,这个案件还有很多事实不清楚的地方,还有很多违法的地方,最高人民法院居然不发回重新审核,就这样核准了,那么法治社会的进程我是完全无法理解的。

好了,我知道了。

最高法院核准上海袭警案主犯杨佳死刑

2008年11月26日06:51 京华时报

本报讯(记者 沈佳音)昨晚7点,上海袭警案被告人杨佳的母亲王静梅收到了最高人民法院11月21日签发的刑事裁定书。该裁定书核准了上海市高院维持杨佳死刑的二审判决。据悉,死刑判决将在7日内执行完毕。前天,杨母王静梅亦曾获准赴沪与杨佳见面。


杨佳母亲回家

  昨天下午,记者在其家中见到王静梅时,她正在收拾冰箱里腐烂的蔬菜。她称:“4个月没回来了,冰箱里的菜都坏掉了。”

  王静梅称,杨佳出事后,她就被带到大屯派出所做笔录。第二天深夜,她被派出所工作人员送到了北京市公安局直属的精神病医院安康医院接受治疗。“我自己单独住一间。他们给我一些治精神病的药吃。”

  7月16日,王静梅在医院给上海来的律师谢有明签了委托书,使其成为杨佳一审的辩护律师。她解释说,“当时是为了孩子好。我在这里帮不上忙,总得让孩子有个律师。”

24日曾会见杨佳

  王静梅称,10月31日,她收到了二审“驳回上诉,维持原判”的裁定书。“11月23日上午,医院领导问我想不想见儿子,我当然想了!他们就着手安排,给我拿来了合身的衣服,换掉我身上的病号服。当天下午,医院领导,还有居委会的人,就陪我坐飞机去了上海。”

  24日上午,在上海提篮桥监狱,王静梅见到了儿子杨佳。她称,“他(杨佳)精神状态还好,不怎么说话。我也克制住自己的情绪,免得他担心。我一直叮嘱他,要好好配合警方的调查”。“整个过程不到二十分钟。不过,不管怎样,见到我,对杨佳的情绪也是一种安慰。”

  王静梅称,临走前,她还给杨佳留下了1000元钱,托狱警代收。随后,应她的要求,她又在饭店见到了杨佳案二审的审判长徐伟,询问了案子的情况。王静梅表示,她告诉徐伟,由于一二审自己都缺席了,希望回去写点材料,以有利于杨佳案的审理。

  王静梅还表示,她正在准备材料申诉。

7日内执行死刑

  昨晚7点30分左右,记者突然接到王静梅的电话称:“告诉你一个事,最高法的死刑复核已经下来了。”

  她称,7点左右,来了两个上海高级人民法院的法官,向她送达了最高法的刑事裁定书。该文的签发日期是11月21日。文中核准了上海市高级人民法院的二审判决。

  “他们说,7天之内执行,可以要求见最后一面。”王静梅称,“我想再见儿子一面,但不知道还能不能见着。”

  昨天,死刑复核阶段的辩护人吉剑青律师表示,自己尚不知道这个消息,今天上午等上海高院上班就去问问。

【共同社上海11月15日电】来自日本山形县鹤冈市的富樫史生在中国历时两个月骑自行车行走约3000公里,于15日顺利抵达目的地上海。富樫在中国旅行 期间相继与他曾经照顾过的中国赴日留学生会面重叙友情。富樫曾就职于国际交流基金日中交流中心,负责邀请中国高中生前往日本学习生活一年的工作,期间与 74名学生建立了友谊。

  受中国产饺子致人中毒等事件的影响,日本社会的对华感情恶化。一些留学生悲观地表示“尽管我们想成为交流的桥 梁,但仅凭借自己的力量什么也无法改变”。富樫听后倍感吃惊,于是决定前往中国鼓励已经回国的学生。富樫9月21日从长春出发,途经沈阳、北京、南京等 地,途中与曾经留学日本的40多名大学生和高中生再次会面,加深了交流。

  学生们对再次见到富樫感到很高兴,表示“还想再去日本”。富樫说:“为了加深相互理解,希望更多的日本年轻人能前往中国,接触普通民众。”

  【共同社9月9日电】(记者 古畑康雄)一位名叫富樫史生的日本男子将于14日开始从长春到上海约3千公里的骑车游中国之旅。现年40岁的富樫生于山形县,长期以来一直致力于日中民间 交流。他此次“千里走单骑”的主要目的是看望曾在其供职的国际交流基金会邀请下赴日本留学的中国学生,再叙友情。他期待“骑着自行车悠闲地环游整个中国, 同时结识不同的中国人”。

   截至今年春天,富樫一直在国际交流基金会的日中交流中心任职,负责2006年启动的“心连心中国高中生长期访日”项目。他专为远离亲人赴日本高中留学一 年的中国学生提供帮助,并与许多中国年轻人成为朋友。富樫表示“非常想了解他们回国后的发展情况”,此次借离职之机他终于决心一圆骑车环游中国的夙愿。

  富樫计划14日到达长春,以日中交流中心设在长春的“日中交流之窗”为起点,途径沈阳、北京、天津、济南、南京、苏州,最终抵达目的地上海。途中他将与约40名曾留学日本的朋友相聚。预计富樫将于11月中旬到达上海。他将通过博客记录下旅途中的见闻。

  此次的旅费将由富樫自己负担,自行车将由他在环游台湾时结识的知名自行车制造商免费提供。

  富樫说旅行是他最大的兴趣,此前他曾游历了约60个国家和地区。2004年他徒步环游台湾,并参观了当地的约50所小学。这一壮举动引来台湾媒体的大幅报道。

  富樫说:“对于40岁的我来说,长途自行车之旅确实充满了艰辛。但我想告诉中国的年轻人,无论年龄有多大,重在勇于挑战。如果大家在路上看到我,请给我加油吧。”富樫旅行中的邮箱地址是net_fumio@yahoo.co.jp。

很多时候,接受惩罚往往是积累经验的起点,甚至是唯一的起点


  1. 做任何事情之前,花上一定的时间分析完成任务所需的种种技能;
  2. 诚实面对自己,正视自己相对于这些技能上的熟练程度;
  3. 如果自己在某些技能上有所欠缺,那么1)短期:求助于他人;2) 长期:求人不如求己——开始学习;
  4. 测算时间,把自己擅长的部分放到后面可能是优势策略;
  5. 养成记录的习惯,以便自己随时监督自己;
  6. 按部就班完成计划。
以上是一个人自我管理之时必备之策略。如果,你是个团队的管理者,那么你的策略可能就要做出一点点的调整——如果把你的整个团队比喻作一个人的话,那么你就是这个团队的“头”。于是,你就要花很长时间分析每个人真正擅长的是什么(并非他声称擅长的)以及真正不擅长的是什么;而后花很长时间分析每个拆分出来的小任务所需之技能,之后的事情就不言而明了。


其实,受到奖励之后,原本有两个选择:1) 再次来过;2) 见好就收。好玩的是,绝大多数人会自动忽视第二个选项(这就是为什么“庞兹骗局”生生不息的根本原因)。受到惩罚之后,同样有两个选项:1) 从此碰都不碰那件事情;2) 挣扎着找一个出路。同样好玩的是,这次绝大多数人还是会自动忽视第二个选项。


很多人实际上根本不知道自己所谓的“喜欢做某件事情”实际上更可能只不过是因为那件事情相对简单、容易获得奖励而已。


A做了一件事情,即,A有一个动机,而后为了实现这个动机(Motivation)而实施了行为(Action)。而现实生活中,A之外其他的人很可能会 基于种种原因评价A的动机与行为。然而,每个人做出评价的方法、目的、手段、角度、出发点、以及能力等等都各不相同。于是评估结果自然常常大相径庭,甚至 天壤之别,更甚至“黑白颠倒”。


如果A感觉自己真的被非议了,那么其实A已经在假定一件事情:自己的所作所为,从动机到结果及其行为的过程中都是合理合法的;是因为别人理解错了、判断错了,所以才对A不满,或对A的动机、行动、行动结果不满。

如果A真的确定自己没错,那么最佳的策略就是“继续走自己的路”,而不去理会所谓的“非议”。道理也特别简 单:1) 既然对A进行非议的那些人已经理解错了、判断错了,说明他们的理解力、判断力都有问题,于是A的进一步的解释、辩解还是会被理解错、判断错——争辩是徒劳 的;2) A还要做更多的事情,而时间是“排它性”资源;所以,与其花时间去争辩,还不如花时间去做更多事情。

当然,很多的时候,我们会发现很多所谓的“非议”其实不见得真的是“非议”,相反,是非曲直很可能真的需要大家议论才更加清楚。人真的需要常常自省,否则就会做到“自残不已”,然后“死而后已”。

在我教书多年的过程中,亲眼看到相当数量的学生仅因为所谓的“非议”而干脆放弃前行。这是一种与智商没关系的下意识的愚蠢——用别人的错误惩罚自己,给别人机会去印证他们的错误

事实上,很多事情回头看会变得更加清晰。历史也是如此,有的时候历史越远越清晰。当A前行许久,回头再看的时候,他也许会因自己当时问心无愧而又坚持至今而甚感坦然。当然,不能排除另外一种可能性,那就是,当A回头再看的时候,发现自己当初确有谬误而不自知;不过还好,毕竟走过来了,就算当初错了,现在却还有机会清醒,并且因为走得更远而可以做到清醒得更彻底;并且还可能更有能力去改过——这不是人生可庆之大幸是什么呢?

如果自己确实没错,有人愿意说,就让他们说吧,谁都应该有言论自由——哪怕说的是不对的。但是,要知道行动永远比言论更有力量。在言论与行动中做出选择,本质上来看很多的时候是“选正确的还是选容易的”之间的选择。我想埋头做事,且做正确的事,相对更容易活得坦然罢。还有最后一条,也很重要:要坦然承认自己的缺点——这有什么坦然不了的呢?但凡一个人正常,他肯定有缺点、弱点。谁要永远“伟大、光荣、正确”,那我就知道他肯定不是人了。

羊 狼 狮子

上帝把两群羊放在草原上,一群在东,一群在西。上帝还给羊群找了两种天敌,一种是狮子,一种是狼。上帝对羊群说:“如果你们要狼,就给一只,任它随意咬你们。如果你们要狮子,就给两头,你们可以在两头狮子中任选一头,还可以随时更换。”

这道题的问题就是:如果你也在羊群中,你是选狼还是选狮子?

很容易做出选择吧?好吧,记住你的选择,接着往下看。

东边那群羊想,狮子比狼凶猛得多,还是要狼吧。于是,它们就要了一只狼。西边那群羊想,狮子虽然比狼凶猛得多,但我们有选择权,还是要狮子吧。于是,它们就要了两头狮子。

那只狼进了东边的羊群后,就开始吃羊。狼身体小,食量也小,一只羊够它吃几天了。这样羊群几天才被追杀一次。西边那群羊挑选了一头狮子,另一头则 留在上帝那里。这头狮子进入羊群后,也开始吃羊。狮子不但比狼凶猛,而且食量惊人,每天都要吃一只羊。这样羊群就天天都要被追杀,惊恐万状。羊群赶紧请上 帝换一头狮子。不料,上帝保管的那头狮子一直没有吃东西,正饥饿难耐,它扑进羊群,比前面那头狮子咬得更疯狂。羊群一天到晚只是逃命,连草都快吃不成了。

东边的羊群庆幸自己选对了天敌,又笑西边的羊群没有眼光。西边的羊群非常后悔,向上帝大倒苦水,要求更换天敌,改要一只狼。上帝说:“天敌一旦确定,就不能更改,必须世代相随,你们唯一的权利是在两头狮子中选择。”

西边的羊群只好把两头狮子不断更换。可两头狮子同样凶残,换哪一头都比东边的羊群悲惨得多,它们索性不换了,让一头狮子吃得膘肥体壮,另一头狮子则饿得精瘦。眼看那头瘦狮子快要饿死了,羊群才请上帝换一头。

这头瘦狮子经过长时间的饥饿后,慢慢悟出了一个道理:自己虽然凶猛异常,一百只羊都不是对手,可是自己的命运是操纵在羊群手里的。羊群随时可以把 自己送回上帝那里,让自己饱受饥饿的煎熬,甚至有可能饿死。想通这个道理后,瘦狮子就对羊群特别客气,只吃死羊和病羊,凡是健康的羊它都不吃了。羊群喜出 望外,有几只小羊提议干脆固定要瘦狮子,不要那头肥狮子了。一只老公羊提醒说:“瘦狮子是怕我们送它回上帝那里挨饿,才对我们这么好。万一肥狮子饿死了, 我们没有了选择的余地,瘦狮子很快就会恢复凶残的本性。”羊群觉得老羊说得有理,为了不让另一头狮子饿死,它们赶紧把它换回来。

原先膘肥体壮的那头狮子,已经饿得只剩下皮包骨头了,并且也懂得了自己的命运是操纵在羊群手里的道理。为了能在草原上待久一点,它竟百般讨好起 羊群来。为羊群寻找水源和草场,甚至为了保护羊群不被前来骚扰东边的那头狼吃掉,去恐吓威胁殴打东边的狼。而那头被送交给上帝的狮子,则难过得流下了眼 泪。

西边的羊群在经历了重重磨难后,终于过上了自由自在的生活。东边的那群羊的处境却越来越悲惨了,那只狼因为没有竞争对手,羊群又无法更换它,它 就胡作非为,每天都要咬死几十只羊,这只狼早已不吃羊肉了,它只喝羊心里的血。它还不准羊叫,哪只叫就立刻咬死哪只。更可恨的是,那匹狼为了不让它肯定打 不过的西边那头狮子来寻它的晦气,竟定时向西边的狮子提供从东边羊群里精挑细选出来的肥羊,讨好从来吃不到活羊的狮子。东边的羊群只能在心中哀叹:“早知 道这样,还不如要两头狮子。”

Peter Paul Rubens's copy of The Battle of Anghiari


The Battle of Anghiari (1505) is a lost painting by Leonardo da Vinci at times referred to as, "The Lost Leonardo", which some commentators believe to be still hidden beneath later frescoes in the Hall of Five Hundred (Salone dei Cinquecento) in the Palazzo Vecchio, Florence. Its central scene depicted a fierce battle between two men riding raging war-horses.

A painting by Peter Paul Rubens in the Louvre, Paris, known as The Battle of the Standard, is believed to be a copy of a copy of the actual painting by Leonardo himself. Rubens made the painting in 1603, based on an engraving by Lorenzo Zacchia from 1558. There are several differences from the original, but Rubens succeeded in portraying the fury, the intense emotions and the sense of power that were present in the original painting. Similarities can also be noted between this Battle of Anghiari and the painting Hippopotamus Hunt he made in 1616.

...

Maurizio Seracini, an Italian expert in high-technology art analysis, believes that behind one of these murals by Vasari, the "Battle of Marciano in Val di Chiana" (1563), is hiding the original fresco of Leonardo da Vinci. On top of Vasari's fresco, 12 meters above the ground, a Florentine soldier waves a green flag with the words "Cerca trova" ("He who seeks, finds"). These enigmatic words seem to be a hint by Vasari, who always spoke highly of the fresco of Leonardo da Vinci.

Seracini believes it is unlikely that Vasari would have destroyed the work of his predecessor during his renovation of the Hall of Five Hundred. Using non-invasive techniques, such as high-frequency, surface-penetrating radar and thermographic camera, Seracini made a survey of the hall. Among other conclusions, he found out that Vasari had built another wall in front of the east wall where the original fresco of Leonardo da Vinci was reported to be located. He found a gap of 1 to 3 centimeters between the two walls, large enough for the older fresco to be preserved.

Early 2007, the city council of Florence and the Italian Minister of Culture have given the greenlight for further investigation. However, they did not find anything else yet.



(from wikipedia)

Maurizio Seracini

Maurizio Seracini is a diagnostician of Italian art. A '73 UCSD Alumus, graduated in bioengineering from the University of California, San Diego (UCSD), he founded, in 1977, the first company in Italy for diagnostic and non-destructive analyses on art and architecture, the Editech srl, Diagnostic Center for Cultural Heritage in Florence.Adapting technologies from the medical and military fields and other technical measuring instruments he has made possible diagnostics of art and search for art without destroying the artwork itself.

Seracini has been well known for his search for the Leonardo da Vinci mural, The Battle of Anghiari in the Salone dei Cinquecento, Palazzo Vecchio, Florence and for his diagnostic survey on Da Vinci's Adoration of the Magi.

Adoration of the Magi Leonardo da Vinci, 1481



The Adoration of the Magi is an early painting by Leonardo da Vinci. Leonardo was given the commission by the Augustinian monks of San Donato a Scopeto in Florence, but departed for Milan the following year, leaving the painting unfinished. It has been in the Uffizi Gallery in Florence since 1670.

The Virgin Mary and Child are depicted in the foreground and form a triangular shape with the Magi kneeling in adoration. Behind them is a semicircle of accompanying figures, including what may be a self-portrait of the young Leonardo (on the far right). In the background on the left is the ruin of a pagan building, on which workmen can be seen, apparently repairing it. On the right are men on horseback fighting, and a sketch of a rocky landscape.

The ruins are a possible reference to the Basilica of Maxentius, which, according to Medieval legend, the Romans claimed would stand until a virgin gave birth. It is supposed to have collapsed on the night of Christ's birth (in fact it was not even built until a later date). The ruins dominate a preparatory perspective drawing by Leonardo, which also features the fighting horsemen, but were relegated to the background in the final painting. The palm tree in the centre has associations with the Virgin Mary, partly due to the phrase 'You are stately as a palm tree' from the Song of Solomon, which is believed to prefigure her. Another aspect of the palm tree can be the usage of the palm tree as as a symbol of victory for ancient Rome, whereas in Christianity it is a representation of martyrdom--triumph over death-- so in conclusion we can say that the palm in general represents triumph. The other tree in the painting is from the carob family, the seeds from the tree are used as a unit of measurement. They measure valuable stones and jewels. This tree and its seeds are associated with crowns suggesting Christ as the king of kings or the Virgin as the future Queen of heaven, also that this is nature's gift to the new born Christ. As with Michelangelo's Doni Tondo the background is probably supposed to represent the Pagan world supplanted by the Christian world, as inaugurated by the events in the foreground.

Leonardo develops his pioneering use of chiaroscuro in the image, creating a seemingly chaotic mass of people plunged into darkness and confusion from which the Magi peer towards the brightly lit figures of Mary and Jesus, while the pagan world in the background carries on building and warring unaware of the new revelation.

Due to Leonardo's inability to complete the painting the commission was handed over to Domenico Ghirlandaio. The final altarpiece was painted by Filippino Lippi and is now also at the Uffizi.

In 2002 Maurizio Seracini, a technical specialist on art diagnostic, was commissioned by the Uffizi to undertake a study of the paint-surface to determine whether the painting could be restored without damaging it. He concluded that it could not and he argued that only the underdrawing was done by Leonardo da Vinci, the paint surface having been added by another, weaker, artist. He stated that "none of the paint we see on the Adoration today was put there by Leonardo". To demonstrate the results of his diagnostic survery on the Adoration of the Magi, Seracini completed more than 2400 detailed infrared photographic records of the painting's elaborate underdrawing, and scientific analyses. Many art historians are currently unconvinced by Seracini's interpretation of his own results.

The painting is the central item in the Andrei Tarkovsky's final film The Sacrifice.

很多情侣看了后,晚上再不关机了!(感人故事)

毕业时,女孩子对男孩子说:我要去北京,北京的中关村有中国硅谷之称,那里机遇多,以后容易发达。
男孩子说:那我就回四川老家,那里是天府之国,美女多,以后你发达了不要我,我容易再找。

女孩子的小拳头在男孩子厚实的胸前轻敲,嘟起了小嘴儿,说你就知道想美女,哼,就算以后我不要你了,你也只能想着我爱着我,不许你找别的女孩子。

男孩子握住女孩子的手,深情的在她的额头印上一吻,说,傻丫头,咱们的父母都在四川呢,你去北京了,我这个好女婿,当然得回去照顾岳父岳母啦。

女孩子的星目里闪着泪花,投进男孩子的怀里,再也不起来。

两人异地相隔但是情愫不减,浓浓的相思当然只能靠无线电波来传递,发短信,打电话,两个人向祖国通讯事业的营业额尽心尽力的贡献着。

一天,女孩子在网上读到一个故事,说的也是一对情侣的故事,每次打电话,那个男孩子都会等女孩子先挂电话,当女孩子经历了世事沧桑之后,她才发现,原来这个世上最爱自己的男人,就是那个每次打电话都等自己先挂的男孩子。

女孩子记住了这个让她唏嘘流泪的故事,那天晚上打完电话,她对男孩子说:你先挂电话。

男孩子一愣,说,傻丫头,打电话还分什么先后啊。

女孩子撒娇,说,不嘛不嘛,就得你先挂电话,不听我以后不理你了,让你找不到老婆。

男孩子停了几秒钟,轻笑了下,说知道了傻丫头,为了以后我不打光棍儿,我就先挂了哦,就知道浪费电话费。

女孩子听见男孩子挂断电话后传来的第一声线路忙音,她开怀的一笑,在心里对男孩子说:亲爱的,我爱你,比你爱我的还要爱。

从那以后,两个人打电话,每逢说到再见,她便握住手机静静的听,等男孩子先挂。而男孩子总会笑着亲昵的叫她一声傻丫头,便挂断了电话。

时间久了,女孩子渐渐的感到一丝淡淡的委屈:你知道吗你,哼,每次我都等你先挂电话,我这么默默的爱你,你却一点也不知道。她想让男孩子也看看那篇文章,让他知道自己多么爱他,哪天他也能等自己先挂一次电话,自己能切切实实的感受下什么叫被爱,该多好啊。

女孩子忍住了,她的幸福中既有甜蜜又有酸涩,她想:能这么一辈子以一个独特的方式深切的爱一个男人,也是一种幸福吧。

跟所有的北漂一样,女孩子的日子过的并不舒适,但是能住在筒子楼里,相比那些住地下室的北漂们,女孩子的生活条件算不错的了。初时的雄心壮志已经被磨的只剩下一个小小的尾巴,但是好强的女孩子并没有向男孩子抱怨过什么,她只是更习惯于对男孩子说那句我爱你。

筒子楼所在的那个社区治安不太好,甚至还有一个专偷女性内衣的变态狂。以前有同租的女孩儿陪伴,女孩子并没有感觉怎样,但是那个女孩儿因为家里有事告假回家了,留下女孩子一个人住在两室一厅一厨一卫的房子里,她很自然的感觉到孤单害怕。

那夜,女孩子在睡梦中被一阵窸窸窣窣的声音惊醒,仔细的听了下,是房门口传来的声音。她抓紧被角,浑身抖作一团,大气不敢出,无助的泪水无声的从眼中涌出来。

突然,她的手碰到枕下的手机,仿佛抓住了救命稻草,立刻给男孩子发了一条短信:亲爱的,我怕。
其实男朋友远在四川,就算一个信息能起什么作用呢?更何况大半夜的,男孩子可能早关机睡觉了。女孩子忘记了要先报警,在这个最害怕的时刻,她只想起了男孩子。

令女孩子惊喜的是,信息发出后几秒钟,男孩子的电话打进来了。她轻轻的接通,听见里面传来男孩子关切的声音:傻丫头,是不是想我了?

女孩子尽量压低自己的声音,向男孩子说现在她一个人住在房子里,门外可能有贼,她好害怕。

男孩子安慰女孩子别怕,他想了想,对女孩子说:把你的手机外放喇叭打开,把声音开到最大,你慢慢去门口,别怕,亲爱的,相信我,别怕。

女孩子冰雪聪明,男孩子一说,她就想到了男孩子的意图:男孩子大声喊话,让外面的人知道,屋里有男人,偷东西或者打别的主意的人,识相的就快走。

女孩子战战兢兢的梛到门口,把手机的外放喇叭打开,声音开到最大后,她轻轻的对话筒说:好了,我在门口了,外放小喇叭也打开了。

这时候女孩子确认外面有人,而且不是一个,可以听见他们微微的对话声。

正当女孩子的身体抖的将要站立不住时,手机里突然大喊一声:***,谁在外面搞我的门啊?屋里的哥儿几个都起来,有客人来了。

男孩子的声音高亢而粗犷,在寂静的黑夜了把女孩子吓了一大跳。不过门外的人可能被吓得跳的更高,女孩子只听见一阵扑通扑通的脚步声由近而远,看样子是被吓走了。

女孩子舒出一口气,腿一软,摊在地上。

男孩子等了一会儿,轻轻的问:外面的人走了吗宝贝?

女孩子终于哭出来,对着手机说,亲爱的,我想你。

女孩子惊魂未定,男孩子便一直安抚女孩子,那一夜,两个人捧着电话说到天明,女孩子说快挂断吧,打了这么久长途,得花多少钱啊。

男孩子笑着说真是个傻丫头,女孩子说就傻,傻才会看上你啊,挂了吧亲爱的,今天上班小心睡着被老板K哦。

挂断电话后,女孩子心里一团甜蜜,她享受男孩子给她的安全感,不过美中不足的是,男孩子似乎已经形成先挂电话的惯例了,这次也不例外,女孩子心想:他虽然很好,但是到底不像那个故事中的男孩子爱女孩子那样深的爱我,他都没有让我先挂过电话。

天开始热了,女孩子的很多单衣上面都没有口袋,所以很多时候她都忘记带手机,比如下班吃饭时手机忘在办公桌上,比如跟室友出去玩时手机忘在租房里,每次她 回来都会收到男孩子的未接电话和信息,也只有这些时候,她才会感觉公平点:哼,每次都先挂我电话,不能及时接你电话,就算是小小的惩罚吧,不许委屈啊,笨 猪。

五月十二号,普通的不能再普通的一天,女孩子在那个小公司里兢兢业业的做着自己的事,为自己的那点小小的梦想不懈的拼搏着。

快下班时,办公室里传起来一个消息:发生了大地震,四川汶川是震中,据说震级跟唐山大地震差不多。

女孩子心里一惊,下意识的向口袋里掏手机,忘记带!

她立刻拿起办公室里的座机给男孩子打电话,但是拨过去信号就断,再拨家里的座机号码,还是不通,看来四川的通讯设施也被地震破坏殆尽了。

一种不祥的预感涌上心头,心急如焚的女孩子再等不及下班,从写字楼里冲下来,招了一辆出租车就向自己租住的筒子楼赶去。

打开手机,竟然有五十多条未接电话,全部是男孩子打来的,她一翻,还有一条未读短信:

宝贝,亲爱的,傻丫头,用尽我今生所有的爱叫你,我爱你,比你爱我还要爱。
自从那次你坚持让我先挂电话,我就知道,你肯定也看过了那个故事,可是,亲爱的,我想告诉你,我爱你,比你爱我还要爱。
其实我也看过那篇故事,很早就看过,那是一个美丽的故事,因为有所憾而美,但是那不属于我们,我不要那种美,那种缺憾的美,我不要!刻骨铭心必将伴随着撕心裂肺,我宁愿两个人平平安安的过一辈子,也不要那种刻骨铭心,我只想伴你过一生,携子之手,与子偕老。


我不要那种凄惨的美,我只要实实在在的幸福。我从来不敢忘记带手机,我怕哪天你会想我,如果我没带手机,我怕你也会同我一样沮丧,很多时候,即使是上厕 所,我也要把手机揣兜里;我晚上从来不关机,每晚睡前我都更换一次电池,再把铃声调大,我怕你哪个夜里会害怕想跟我说话,如果我关机,你在异乡会更加孤 独。
你每次都让我先挂电话,我知道那是因为你爱我,我很开心,想起来总是眼里潮潮的;我的电话从来不关机,你却不知道,那是因为我更爱你,别怪我没告诉过你,我的宝贝,我是想等到咱们都老成妖怪时再说。
傻丫头,看样子我是没有那个陪伴你一生的福气了,我背上的那块预制板,已经压了我两个多小时,我的整个胸部背部都撕裂般的疼痛,我还能闻见自己流出血的腥味儿,宝贝,我可能无法再陪你继续走下去了。
亲爱的,我想听听你的声音,我一遍遍的打你的手机,你为什么不接啊?亲爱的,你听见我在呼唤你吗?亲爱的,这里好黑,我好冷,我想让你抱着我。
亲爱的,我的亲爱,我的宝贝,我爱你,我此刻是如此怯懦如此怕死,因为那意味着我再不能吻你疼你。我更担心的是你会因为我而伤心欲绝,别那样,亲爱的,我 走了,你在北京再找一个人照顾你,那里成功人士多,机遇多。你是天堂里最圣洁的天使,没有人在你身边保护,我怕你会受到伤害。
答应我,亲爱的,如果还有一个男人像我这样爱你,千万别不接他的电话,我知道他那时会有多痛。

我不能呼吸了,宝贝,再见了,来世,我一定要做你老公!
宝贝,亲爱的,傻丫头,再次用尽我今生所有的爱叫你,我爱你,比你爱我还要爱。

女孩子的泪水似江水决堤,哭到来不及呼吸,她仰头向天,紧闭着双眼发出撕心裂肺的呼喊:
亲爱的,下辈子我还做你的老婆,我再也不会关机了。




札幌的雪,真的很漂亮很漂亮。。。
(在学校照的)

沈阳的第一场雪

今天,沈阳下了入冬后的第一场雪。

从小就很喜欢雪,雪中有我的很多记忆,很多美好的瞬间,很多很多。。。

相比之下更喜欢札幌的雪,因为它太静,太纯,太白,太美了。。。

昏暗的灯光中飘落着雪花,让我想起了一封她的信。

亲爱的,你在那里,还好吗?。。。

toefl

尽管在打开成绩单之间祈祷了一下--结果还是那么惨。没有上次高,挺让我惊讶的一个成绩。口语竟然出奇的低,事实上什么都不高。

晚上又报了一个十天后的,反正最后的一下子了,不过100的话也必须硬着头皮上了,因为没有时间和精力和金钱让我再去试试了。求你了,满足我的愿望吧。

烧高香。。。sat过2000, toefl过110,お願いします~~~

MIT 1

When we admit a class of students to MIT, it's as if we're choosing a 1,000-person team to climb a very interesting, fairly rugged mountain - together. We obviously want people who have the training, stamina and passion for the climb. At the same time, we want each to add something useful or intriguing to the team, from a wonderful temperament or sense of humor, to compelling personal experiences, to a wide range of individual gifts, talents, interests and achievements. We are emphatically not looking for a batch of identical perfect climbers; we are looking for a richly varied team of capable people who will support, surprise and inspire each other.

......

By the same token, some applicants struggle to turn themselves into clones of the "ideal" MIT student - you know, the one who gets triple 800s on the SAT. Fortunately, cloning is still for sheep. What we really want to see on your application is you being you - pursuing the things you love, growing, changing, taking risks, learning from your mistakes, all in your own distinctive way. College is not a costume party; you're not supposed to come dressed as someone else. Instead, college is an intense, irreplaceable four-year opportunity to become more yourself than you've ever been. What you need to show us is that you're ready to try.

网飞三体 第一季观后感

 之前看过b站的动画三体,然后是腾讯的三体剧,最后看的才是这个网飞的三体。 动画三体里面对角色外形之类的设定比较追随原著,剧情上面也还好,虽然我没看完。腾讯的三体剧我好像也没看完,但是观感就是除了大史跟想象不一样之外其他的内容比较忠于原著。但是由于审查限制,一到关于警察就神乎其神...
