今天在《卫报》上看到一则新闻,关于加拿大发生的一起严重交通事故,标题是加拿大:“卡车与小型曲棍球队巴士发生碰撞后造成多人死亡”。随后加拿大总理在推特上写到:“我无法想象遇难者的父母正在经历经历怎样的场景,这场严重的事故牵动着我和所有人的心……”

世界上每天都发生着各种各样的事情,充满着不确定性,就像这则新闻中的一群年轻人,可能安全抵达比赛场地,尽情比赛后获得大奖,然而, 一场交通事故夺去了他们的生命。

我们经常谈论的“命运”是一个永恒的话题,她到底存在吗?是什么决定的一个人的“命运”?我理解的狭义的命运就是过去的人生对现在的反应,以及决定自己的未来。

A sad news reported  from The Guardian  today thatCanada: multiple deaths after truck collides with junior hockey team bus”.The Prime Minister of Canada Justin Trudeau said  “I cannot imagine what these parents are going through, and my heart goes out to everyone affected by this terrible tragedy…”in Twitter .

There are many different things happens in the world every moment, And it is full of uncertainties. Just like this group of  young people  above the news, they will arrive  at the playground on time and enjoy the match, However, they lost their life due to the serious traffic accident .

We usually talk about the “fate” is an everlasting topic, Does the fate really exist? And what determines the “fate” for one ? In my view, the “fate” is the reaction of past life to present and it is the influence of  future on  one’s life in the narrow sense .

A Short Discussion On Spoken English and Written English

As a English beginner since I graduated from the primary school,and my major is English in the college,”Do you speak English?”,this is far more commonly asked by other people  whom they come into contact than “Do you write English?”,they perhaps laugh at the idea of having studied  English for years without being able to speak it,the sense of  shame comes for me…

Nor do I mean that one’s aim in learning English is simply to speak it,but good speaking leads good writing and that language is essentially something spoken.To learn to speak is a good way to write,and the nature of the English sentence is simple and concise and avoid the chinglish as possible.

Honesty 、modesty and rigour are the most important quality for one no matter what kind of work ,especially in learn a language.

The city  suffered a massive dust  today.

I stay in the laboratory  whole day corrected my thesis based on other’s suggestions.the problems still existent and in particularly it was lack of the logic .thus, the logic is a key  factor whether  in Chinese or English article. an American professor used to emphasize a written skill for his students that “spend 45 minute everyday reading Washington Post,and you will be cruising with your written  English in two years ”,the written and reading is closely related for each language.

I want to speak fluent English and  write the accuracy article…this is a simple sentence that does not have any meaning,I must to put my decision into practice, it takes a lot of practice to write the article well.

As a Chinese poem reads no matter how high the mountin is, one can always assend to its tops.(华山再高,顶有过路)

A new day has come! the night is peaceful,and my heart is also quiet with the english songs from computer.

I was working  to finish my thesis whole day ,I felt the time is fast vanished,in particular these days,and that day I will never forgot in my life. I have no patience before,however,I am changed so much now,as long as existing some disadvantages,I know my potential power and patience is the key factors to obtain the achievements belongs to me.

“If you haven’t an ability that is to sit on you desk for a long time,” if you are inconformity to study or do research”,this word from a Taiwan’s scholar who died in last mouth,he is a famous thinker and writer,especially as a critic.he is a legend for an age,I am worship him in some sapect.

I solved a final problem today in my thesis today ,so excite now ,but the work is not prefect,it needs further improved next.and another good news from Marinia that she may come to here this summer,miss her day and night, It’s a strong power that I keep energy every moment.

She stay late these days for her paper,working in CAS could foster one’s self-dependence and improve work and study efficiency .

It was a Sunday evening in theApril,and today is my father’s birthday at 16th January of lunar calendar.he was 59 years old this year and will retire soon.

my father working in the local government department for many years,he is hardworking for his job,but he is lasy in my impression,he like sleep in daytime and have a bad temper,always express his dissatisfaction surrounding us , and we usually suggests he change this behavior,however,it’s difficult for him.

He sent his self-photograph by wechat today,I felt he becomes old ,the time is equal for every person, I hope he still keep health in the future.

Beijing is the capital of China and located in the north of the chinese mainland,Beijing became the country’s capital at the start of the Ming dynasty in 1421 ,and  bacame the new capital of the P.R.C in the year 1949,

It’s my first time went to Beijing in summer last year, the journey from Lanzhou to Beijing takes about 15 hours by train. Marinia arrived train station wait for me in advance,then we take the subway came back to her institute.

The Summer palace,Tien an men Square  and the Great Wall are the most famous sight spot in Beijing, Marinia and I visited the first two spot in second day,excited for me ,I felt a strong history and cultural in summer palac,I am looking foreword to climbing the Great Wall with Marinia at the next time.

My first English note 2018

It was around 8 o’clock p.m.,  I was sitting at my desk and preparing for a diary with computer .

I have had a haircut after dinner, a short haircut as usual ,it seems to be spirited for a young person in Chinese culture,and short haircut represent a simple principle and higher efficiency in daily life in my view. My girl friend Marinia (sweetheart muqi)also have had a short haircut a few days ago, I still remembered muqi with a long hair when I meet her in September 2014, that was fascinated for me, she was a girl of great beauty now and forever in my eye and  bottom of my heart .

The weather was terrible whole day with a light fog and haze ,I know every season has it’s characteristics,but human’s activity may causes the poor air pollution now,such as industry emissions excessively,the clear air was the most valuable resources for each person today.

Adhere to write an English dairy or a composition everyday is necessary ,and I hope marinia  modified  and supervised me in her spare time.

“Letters to a young scientist”– By E.O. Wilson

What I’m going to do is to just give a few notes, and this is from a book I’m preparing called “Letters to a Young Scientist.” I’d thought it’d be appropriate to present it, on the basis that I have had extensive experience in teaching, counseling scientists across a broad array of fields. And you might like to hear some of the principles that I’ve developed in doing that teaching and counseling.

So let me begin by urging you, particularly you on the youngsters’ side, on this path you’ve chosen, to go as far as you can. The world needs you, badly. Humanity is now fully into the techno-scientific age. There is going to be no turning back.

Although varying among disciplines — say, astrophysics, molecular genetics, the immunology, the microbiology, the public health, to the new area of the human body as a symbiont, to public health, environmental science. Knowledge in medical science and science overall is doubling every 15 to 20 years. Technology is increasing at a comparable rate. Between them, the two already pervade, as most of you here seated realize, every dimension of human life.

So swift is the velocity of the techno-scientific revolution, so startling in its countless twists and turns, that no one can predict its outcome even a decade from the present moment.

There will come a time, of course, when the exponential growth of discovery and knowledge, which actually began in the 1600s, has to peak and level off, but that’s not going to matter to you. The revolution is going to continue for at least several more decades. It’ll render the human condition radically different from what it is today. Traditional fields of study are going to continue to grow and in so doing, inevitably they will meet and create new disciplines.

In time, all of science will come to be a continuum of description, an explanation of networks, of principles and laws. That’s why you need not just be training in one specialty, but also acquire breadth in other fields, related to and even distant from your own initial choice.

Keep your eyes lifted and your head turning. The search for knowledge is in our genes. It was put there by our distant ancestors who spread across the world, and it’s never going to be quenched. To understand and use it sanely, as a part of the civilization yet to evolve requires a vastly larger population of scientifically trained people like you. In education, medicine, law, diplomacy, government, business and the media that exist today.

Our political leaders need at least a modest degree of scientific literacy, which most badly lack today — no applause, please. It will be better for all if they prepare before entering office rather than learning on the job. Therefore you will do well to act on the side, no matter how far into the laboratory you may go, to serve as teachers during the span of your career.

I’ll now proceed quickly, and before else, to a subject that is both a vital asset and a potential barrier to a scientific career. If you are a bit short in mathematical skills, don’t worry. Many of the most successful scientists at work today are mathematically semi-literate.

A metaphor will serve here: Where elite mathematicians and statisticians and theorists often serve as architects in the expanding realm of science, the remaining large majority of basic applied scientists, including a large portion of those who could be said to be of the first rank, are the ones who map the terrain, they scout the frontiers, they cut the pathways, they raise the buildings along the way.

Some may have considered me foolhardy, but it’s been my habit to brush aside the fear of mathematics when talking to candidate scientists. During 41 years of teaching biology at Harvard, I watched sadly as bright students turned away from the possibility of a scientific career or even from taking non-required courses in science because they were afraid of failure. These math-phobes deprive science and medicine of immeasurable amounts of badly needed talent.

Here’s how to relax your anxieties, if you have them: Understand that mathematics is a language ruled like other verbal languages, or like verbal language generally, by its own grammar and system of logic. Any person with average quantitative intelligence who learns to read and write mathematics at an elementary level will, as in verbal language, have little difficulty picking up most of the fundamentals if they choose to master the mathspeak of most disciplines of science.

The longer you wait to become at least semi-literate the harder the language of mathematics will be to master, just as again in any verbal language, but it can be done at any age. I speak as an authority on that subject, because I’m an extreme case. I didn’t take algebra until my freshman year at the University of Alabama. They didn’t teach it before then.

I finally got around to calculus as a 32-year-old tenured professor at Harvard, where I sat uncomfortably in classes with undergraduate students, little more than half my age. A couple of them were students in a course I was giving on evolutionary biology. I swallowed my pride, and I learned calculus.

I found out that in science and all its applications, what is crucial is not that technical ability, but it is imagination in all of its applications. The ability to form concepts with images of entities and processes pictured by intuition. I found out that advances in science rarely come upstream from an ability to stand at a blackboard and conjure images from unfolding mathematical propositions and equations. They are instead the products of downstream imagination leading to hard work, during which mathematical reasoning may or may not prove to be relevant. Ideas emerge when a part of the real or imagined world is studied for its own sake.

Of foremost importance is a thorough, well-organized knowledge of all that is known of the relevant entities and processes that might be involved in that domain you propose to enter. When something new is discovered, it’s logical then that one of the follow-up steps is to find the mathematical and statistical methods to move its analysis forward. If that step proves too difficult for the person or team that made the discovery, a mathematician can then be added by them as a collaborator.

Consider the following principle, which I will modestly call Wilson’s Principle Number One: It is far easier for scientists including medical researchers, to require needed collaboration in mathematics and statistics than it is for mathematicians and statisticians to find scientists able to make use of their equations. It is important in choosing the direction to take in science to find the subject at your level of competence that interests you deeply, and focus on that.

Keep in mind, then, Wilson’s Second Principle: For every scientist, whether researcher, technician, teacher, manager or businessman, working at any level of mathematical competence, there exists a discipline in science or medicine for which that level is enough to achieve excellence.

Now I’m going to offer quickly several more principles that will be useful in organizing your education and career, or if you’re teaching, how you might enhance your own teaching and counseling of young scientists. In selecting a subject in which to conduct original research, or to develop world-class expertise, take a part of the chosen discipline that is sparsely inhabited. Judge opportunity by how few other students and researchers are on hand.

This is not to de-emphasize the essential requirement of broad training, or the value of apprenticing yourself in ongoing research to programs of high quality. It is important also to acquire older mentors within these successful programs, and to make friends and colleagues of your age for mutual support. But through it all, look for a way to break out, to find a field and subject not yet popular.

We have seen this demonstrated already in the talks preceding mine. There is the quickest way advances are likely to occur, as measured in discoveries per investigator per year. You may have heard the military dictum for the gathering of armies: March to the sound of the guns. In science, the exact opposite is the case: March away from the sound of the guns.

So Wilson’s Principle Number Three: March away from the sound of the guns. Observe from a distance, but do not join the fray. Make a fray of your own. Once you have settled on a specialty, and the profession you can love, and you’ve secured opportunity, your potential to succeed will be greatly enhanced if you study it enough to become an expert.

There are thousands of professionally delimited subjects sprinkled through physics and chemistry to biology and medicine. And on then into the social sciences, where it is possible in short time to acquire the status of an authority. When the subject is still very thinly populated, you can with diligence and hard work become the world authority.

The world needs this kind of expertise, and it rewards the kind of people willing to acquire it. The existing information and what you self-discover may at first seem skimpy and difficult to connect to other bodies of knowledge. Well, if that’s the case, good. Why hard instead of easy?

The answer deserves to be stated as Principle Number Four. In the attempt to make scientific discoveries, every problem is an opportunity, and the more difficult the problem, the greater will be the importance of its solution.

Now this brings me to a basic categorization in the way scientific discoveries are made. Scientists, pure mathematicians among them, follow one or the other of two pathways: First through early discoveries, a problem is identified and a solution is sought. The problem may be relatively small; for example, where exactly in a cruise ship does the norovirus begin to spread? Or larger, what’s the role of dark matter in the expansion of the universe? As the answer is sought, other phenomena are typically discovered and other questions are asked.

This first of the two strategies is like a hunter, exploring a forest in search of a particular quarry, who finds other quarries along the way. The second strategy of research is to study a subject broadly searching for unknown phenomena or patterns of known phenomena like a hunter in what we call “the naturalist’s trance,” the researcher of mind is open to anything interesting, any quarry worth taking. The search is not for the solution of the problem, but for problems themselves worth solving.

The two strategies of research, original research, can be stated as follows, in the final principle I’m going to offer you: For every problem in a given discipline of science, there exists a species or entity or phenomenon ideal for its solution. And conversely, for every species or other entity or phenomenon, there exist important problems for the solution of which, those particular objects of research are ideally suited. Find out what they are. You’ll find your own way to discover, to learn, to teach.

The decades ahead will see dramatic advances in disease prevention, general health, the quality of life. All of humanity depends on the knowledge and practice of the medicine and the science behind it you will master. You have chosen a calling that will come in steps to give you satisfaction, at its conclusion, of a life well lived. And I thank you for having me here tonight.

(Applause)

Oh, thank you. Thank you very much. I salute you.

如果没有机会进行联合培养,没有机会参加全国学术会议,也没有机会参加培训班,还有一个间接的方式,就是多参加学术报告会。大学或学院或实验室,每年都会邀请一些各个领域的专家来做学术报告和学术交流。对于研究生,这也是一个提高的机会,加深对科学的理解。同时,多读科学文献,读上档次的文献,也是一个提高自己的途径。

研究生需要有眼光,有谋划,有行动。要走出去,走高一点,去看看外边的世界,了解外边的发展,清楚自己的现状。在信息时代,更不能做井底蛙。

作为同时代的研究生,学校条件不好,科研氛围不好,导师学术水平也不高,这些都不是自己对待学问糊弄、将就和凑付的理由,也不是自己不上进安于现状的理由。

做学术,就应该到有条件的地方去。

读研究生,就应该到有利于自己发展的地方去。
