After secretly old 80 ( rpm)

 Like stealth, and not very loving to speak in the group are beginning to call their own children
uncle or aunt of the

not so cynical, and when faced injustice, will tell themselves, our society is This
I have found each ~ I know, I'm old ... ...
80 after the unspoken rules of life:
can not watch TV, but the computer is a necessity jumped out
up to three treasures: cell phone, keys, loose change
dozens of pieces never know where the money is spent, not how to eat, not how to wear


negative, refuse to grow up . Do not like to be that mature.
Acquaintance in front of a word chatter, before the silent stranger
there must be a hobby is sleeping
all day long soak in the Internet, do not know what to do. 80 most frequent word is



topic of weight loss is constant and action
hungry, eat regular breakfast, lunch and eat together
typing was quite inaccurate, but still playing Soon before 12am
sleep


rarely anything can be reason for pride. Think that other people can not understand themselves and others as a reason for disdain



80 after we have a lot of dreams, some realized, some shattered.
80 after us, some famous, some unknown.
80 after we had struggled a loss, or survive.
80 after we withdrew the wisdom of youth, young and tender, began to adapt to the community of nations.

our hearts are well aware, we have experienced too much.

family love and cooperation in the sub-sub-sub friendship and cooperation and cooperation

was desperate to have sought, and later becomes worthless too. Blocking things parents had, until his injury,
came to understand, the parents turned out to be right.
have asked yourself many times why alive? Later, have been too lazy to think about the meaning of life.
had for love can not be properly read, and later left to work for love.
now Remember the first dream? Or, how many people have stuck to their youth when the dream.
at home, the parents of our obedience, out of the house, our social obedience.
could not understand things will gradually get used to, do not know this habit is good or bad?
I do not even know my dreams to be?
But one thing is certain, will not make some wild teenage dream.

I care to see it!

A first quad-core server industry want to go beyond domestic manufacturers

 A first quad-core server industry want to go beyond
domestic manufacturers before, with the AMD and Intel quad-core Barcelona quad-core Tigertown new release, indicating that four nuclear war, while an official war, the industry entered into multi-core to quad-core based era. The first cut is the quad-core server industry. so quad-core can widely used in the server industry, will determine the future quad-core can really proliferate.
as early as November last year, Intel's quad-core debut since server vendors have already begun to roll out quad-core server products. just because when Intel introduced the dual quad-core, server vendors also introduced dual quad-core servers. such was the wave of domestic server makers to simultaneously launch the world's first quad-core server products NF380D. Then, in April 2007, the tide in the IDF and Intel jointly announced the world's first quad-core virtualization performance test report, based on the wave of NF380D the overall efficiency of quad-core servers to dual-core server 1.91 times .8, SPEC announced the completion by the tide, the world's first quad-core platforms based on Intel SPECjAppServer2004 benchmark test results, results for the 1538JOPS (the number of transactions per second), not only set a record of the test the best two-way servers, but beyond a certain brand of international minicomputer. on the other server vendors in the country is still competing in the dual-core server market, when the wave of the domestic leader in server vendors have begun to join hands to promote the Intel quad-core applications, the process of industrialization.
in After the wave of domestic server manufacturer Lenovo, Pao, also have launched a quad-core platforms based on Intel's quad-core server, and foreign manufacturers of IBM, HP, Dell and Sun, also joined the race in the quad-core server. quad server market began to horizon.
a time when the September of this year, AMD quad-core release, and more server makers to quad-core camp. dawn clear that performance will be in their future fleet used in AMD's quad-core Barcelona, at the same time, the mainstream server vendors abroad IBM, HP, Dell, Sun, etc. in the original Intel quad-core server also said to be based on the AMD quad-core Barcelona launch with the server. From this quad-core server, the time has come.
is well known, both Intel and AMD have emphasized four core + multi-core virtualization is the future application of industry best in the server mode. And, according to a survey conducted by Forrester Research, IT spending accounts for operations Enterprise IT's total budget 80% m90%. only energy consumption as an example, Google engineer Luiz Andr Barroso after careful calculation of the result is that energy costs have accounted for 40% of hardware cost. In addition, the scale of expansion brought with electricity, heat and other hardware issues, and various software problems, making the system stability suffered increasingly severe challenges, a consulting firm for the customer TCO study shows that enterprises, especially SMEs in the cost of downtime up to TCO of server system 16.7%. To this end, four quad-core + implementation of virtualization is undoubtedly the also allows users, in particular, its difficult for Chinese users across the application threshold.
fact, for the user in terms, virtualization is not a new application of new technologies, and now most customers do not understand virtualization, as a new technology to treat, trust is not enough to virtualization. As the value of server vendors is to integrate industry resources to provide customers with highly available, easily managed virtualization solution, through the free trial, technical support and training to help users across the Yingyong threshold, to make it more quickly adapt to the new application model.
this end, Intel recently invested $ 218,500,000 acquisition of a stake in software company VMware is its emphasis on virtualization best proof of this. As for the server vendors, who can virtualization to conduct extensive cooperation with industry and applications will no doubt be in the future competition in the server industry, living in a favorable position. wave of domestic server makers once again walk in the forefront of other server vendors. When Intel releases new quad-core Tigertown time the first wave of expansion in the domestic and XenSource, SWsoft virtualization software vendors such as strategic cooperation, which makes the wave of quad-core can provide easier deployment of the virtualization market, manageability and cost of better solutions that help customers across the threshold of virtualization to help users to achieve high-performance multi-core applications.
support in addition to server vendors, the Intel dual-core in order to account for the absolute mainstream quad-core market share of the rapid increase, the use of a high-end quad-core products and dual-core pricing policy overlap, This pricing strategy at the Intel processors, the server vendors to quad-core server and dual-core server, pull the spread is very small. the world's top three brands IBM, HP and Dell as an example, Dell PowerEdge 2950 quad-core and dual-core configuration price Like, HP Proliant DL380 G5 dual-core and quad-core configuration only 6% of the price difference, IBM X3650 spread of 8%. In this pricing strategy, the user will naturally select quad-core server.
and as a domestic server companies, and Intel has taken the wave synchronization TTM, the first listing, and high-volume supply market, first cover market strategy, while the rapid completion of full line of server products to switch to quad-core platform. In view of earlier, the tide has been achieved in the four core areas more than the first, such as publishing the world's first quad-core server, the world's first quad-core platforms based on virtualization test, quad-core server SPECjAppServer2004 test world record and so on. coupled with the wave of quad-core strategy around the , the industry believes that the wave of domestic server companies represented in the four core strengths to further enhance the market leader.
waves recently with the simultaneous release of Intel's new quad-core and quad-core server virtualization solution whether it is domestic server makers beyond start?
even more concerns of the industry, in the recently released Intel's new quad-core Tigertown the same time, the wave of synchronized release of two new quad-core servers are based on a grasp of the needs of domestic customers, independent definition of design. and released at the same time innovative technology, launched its own product, and application level integration of industrial action initiated by the system, which is the first time in the domestic server makers.
this mark after many years of accumulated experience and technical resources to integrate with the upstream vendors matures, particularly technical cooperation from Intel PSR blood transfusion, as represented by the wave of domestic server makers have been satisfied with the international vendors to follow, and begin to try to transcend it? Let us wait and see!

Empirical science of economics is so lucky to become far more than two people

 Shocked to learn of contemporary liberal banner of Friedman economics professor at November 16, 2006 death in the United States. I read my September 2004 biography of Frederick the old onwards, but changed the subject to mark the mourning.
as empirical science of economics is this: the lucky far more than two people?
Zhang
Last week, I graduate course on Let the students begin to feel a waste of time. You need a little performance, but also can not charge so much. All in all, a Good course to really, you need well-designed and well-prepared, and the scene should always pay attention in class changes in the expression of students. requirements of their own so the students will eventually win the enthusiasm and patience. With such a design and ideas, all these years, not only face the graduate students, and the face of those who pay high tuition fees of veterans EMBA gentlemen, I can always remain optimistic and confident.
different from the past, this time, my opening of rather than an explanation on the theory of human behavior. To make a landmark contribution to modern economics, a well-known axiomatic mathematician Debreu's book is not called the The economics of science today is part of the experience. I want to choose the first class described in this and related issues of scientific research topic.
scientific problem is always fascinating. read on science and philosophy of science The book is 20 years ago when I was a college preference. Now think about it, read a lot of that time, may not understand much. now read less, but understand more. I guess this may be a person to obtain to increase knowledge of a biological laws bar. Unlike in the past, the past always have a book to see information on the boundary can not be exceeded, and today will be those who can not consciously pick up the boundaries of the book and enjoy more. before the beginning of the week Friedman, I sneak in to read the memoirs of his wife New point. In particular, the
economics class we just teach the achievements of modern economics, but the textbooks are rarely involved in the development of an important stage on the economic history of the story. economics today is the economy we see today Studies like that, what is now the mainstream, although some people do not like this is called. There is no doubt that many people become mainstream economics today made an outstanding contribution. in the ranks, no one can deny that Jeffrey Goldman completed in 1947 and in 1953 as a this paper and from the discussion it caused lasting changes in the descendants of the economics of this 50 years ago, Friedman's bold views on the methodology of economics of the new generation of economists had a lasting influence. and Facts have proved that this epoch-making This paper before actually giving a very high rating. He said: This one is more important, although in this foreword is only subsidiary in the corpus content. It caused controversy after 40 years in not showing signs of subsiding. As Daniel. Hammond said in the article: l that Milton. Friedman's article ...... ...... is the classic reference is nothing new. This article has been published since 1953 has been a tremendous impact on many people ...... generations of graduate students (the majority of people have this) to understand the economics, what it means to become a science. philosopher and methodology scholars regard it as the philosophy of science into economics, Friedman will sign l or r as the marker of the Chicago School. r businessmen do interviews or survey research shows that: l these businessmen making decisions did not actually refer to the chart, curve, multi-variable function shows the marginal cost and marginal revenue r. book, they pay wages equal to those drivers who the driver on the marginal special wrong wrong, Assuming the equilibrium condition established itself, the theory is not explanatory. For example, according to the maximization of static equilibrium theory (state of the business was the best, but in fact only a corporate value judgments rather than the interpretation of choice behavior. And to this on the From this empirical science, or that of empirical science into economics. When we say that when empirical science, its meaning has two basic properties of, first, the theory of economics, there is a rebuttable proposition consisting of the second, It's these propositions can be verified with the facts.
in the interpretation of human behavior, the economics of the variables that can not be observed or treated as assumptions constant, the variable will be observed as a bound variable or explanatory variables. In this way, can simply be defined in the methodology of economics as a Suen in their textbook, > However, the need to especially emphasize that I (for students, which is particularly important to remind), the assumption that the cause or influence people's behavior in many variables, the lack of sufficient empirical information, economics can refute their propositions examination or test only The changes in direction. Therefore, in the comparative static analysis, we have to do is often the determination of derivative (ie rate of change) of the called The fundamental assumption of the business, but also in the value system of microeconomics in business to maximize profits given the strict condition that the whether the enterprise really achieve profit maximization, it is because we do not know business profit maximization means that we experience can not be directly measured and tested to maximize profits on the assumptions and propositions, but the economics are a function can be inferred from the assumption that the proposition to be refuted (which is a comparison of static analysis of the meaning), and can be used to determine the number of observed changes in the number mode, or determination of the relationship between the marginal amount. For example, we can add the profit maximization model rate parameters, and can maximize profits by enterprises under the conditions of logical the number of production parameters on the rate of change in the direction of change made, resulting in a > Today, the comparative statics or But in half a century ago, to look at the economics that people are still very few, and on the methodology of economics can easily cause such a discourse of criticism and controversy. Obviously, the situation today is the idea that people look at the progress of science makes The.
of natural science epistemology or methodology of systematic and creative research, the London School of Economics Popper book, written in German Party 1959 by of economics, is not statistically positive science experiment into the most important component. Mr. Zhang Wuchang once told me that Friedman's work is the most important statistical aspects. Freed Man is a statistical genius. and Friedman's own admission, on the empirical methodology of the most important is that he began a strong interest in statistics. this time, the empirical methodology of thinking, the philosophical basis of statistical also undergoing a is to address the differences between economists are surprisingly similar. Such a statement published in 1957, in Friedman's person not only statistics and quantitative methods to become a member of the family economist, and theoretical explanation of the construction work into a full spiritual activities. as the empirical science of economics, it certainly requires wisdom, reason and emotion. may not This means more experience than Friedman. He wrote half a century ago and remains below this discourse makes food for thought. He said: hypothesis that the existing and improved, and the need to continue to construct new hypotheses. For this problem, people have not reached a final conclusion. tectonic hypothesis is a need inspiration, intuition, creativity and innovation, its essence is to be in people the materials used to find new ideas. This process must be discussed in the areas of psychology, rather than discussing the category of logic; autobiography and biography must be studied, rather than research monographs; must promote justice and examples, rather than by inference or theorem to promote. describes my husband's personality, this is what made his seminal contributions to economics, and its great impact on students.

to two weeks before his death, Charles. Darwin also wrote a short paper, described the discovery in central England, and clamp the legs in a little water clam worm. This is his last post. sent to the Darwin water bug who is a young shoemaker, amateur naturalist named Walter. Delaunay Bridge. Creek. Then the shoemaker married, had a son named Harry; Harry grew up, he called his son in Francis .1953 , Francis. Crick and James Young Americans. Watson made a joint found evidence for the theory of evolution has brought indisputable, so that Darwin made in this area almost all the inferences are given the final victory. This evidence is neither
from fossils, specimens or living organisms, not from organ anatomy, but from a cells carrying a chemical code, recording the life of their own information. This record is used in biosphere mm simple common language, constituted by the four-letter DNA code. Charles Darwin wrote: in all organic life on earth the body, are from the original form of a single pass from Yan. Darwin's successors do not need to guess. They go directly to access to genetic Some very long, others short and small. After he concluded that, despite these differences, but all are close relatives of the Galapagos finch. class insight into the structure of living organisms and the diversity gradient, Later, toward the direction of the evolution of different. breeding species from (bird exist in the world, and the ancestor species genetic color from the latest of which was blunt finches).
as subjects of guppies are constantly close to the glass cylinder wall, after which they will be set free Trinidad streams, ponds scattered in the river cruise.
DNA not only used to confirm the authenticity of biological evolution, but also from the most basic level, it demonstrated biological remodeling of the way. Recently, Al Hart of Harvard University. 阿布扎诺夫 and Harvard Medical School, Cliff. Tabin locked responsible for some of the aforementioned genes beak shape. the so-called genes, that is, a string of DNA letters in the sequence, activated by the cell after that they can guide the synthesis of a particular protein. 阿布扎诺夫 and Tabin found in bird embryos gradually formed in the jaw, when BMP4 protein that is responsible for synthesis of genes is activated (scientists the term expression Sparrow, a calmodulin gene expression make to become thin and long beak. The large cactus finch gene (Gconirostris) the most active, so that they can be stuck with a long beak for seeds cactus fruit eat.
offshore in the Gulf Coast, Florida, a group of islands, the beach mouse's coat color of mice than the continental United States to light. This gives them access to the beach in a better light camouflage mm grown too high-profile mice more likely to be owls, eagles and herons caught, the survivors to reproduce. also worked at Harvard Phi Huo. Hoekstra and colleagues, the source of this difference comes down coat to a gene in a letters change. a mere reduction of the mouse DNA letters to Mao Zhongsheng into pigment. the gene mutation from the beach island 5,000 years ago during the formation of the group is created. Darwin's greatest idea is that a variety of species, between close relatives Most feature a variety of differences caused by natural selection. Now, we finch beaks and fur mice into, you can literally see that natural selection at work, it changes the shape and the DNA sequences of various genes and its expression, so that organisms adapt to specific environments.
Darwin originally conceived, the pace of biological evolution as slow flow of glaciers, and only in the fossil record can get a glimpse of clues. Today, a discovery will make him happy . Among those Galapagos finch Darwin's modern followers see the evolution occurring in real time In 1973, Peter, Rose Mary. Grant, his wife (now at Princeton University) began to observe the annual Dove over the island (of the Galapagos) land birds group. They soon found that with the island back and forth between wet and dry climate change, to the evolution of birds from year to year in the rapidly advancing. For example, the first island only two long-term in this breeding ground finch, one of which is the medium ground finch (G. fortis), with small seeds for food .1977 severe drought in coming years, the island, the little seeds become scarce, medium to bird pecking forced to turn to larger, more hard seeds, which birds an advantage that the larger bill, can survive having children, the mouth pass along genes.
biologists wear dimension. Rizzi Nick regulation of guppies here the level of threat by predators, and then tracking the changes in fish stocks.
1982, a group of large ground finches mm competitors came to the island, they are also big and hard to seeds for food, and later on led to another turn of events. The two species coexisted for many years, the two groups in 2002 have become abnormal growth. Then, drought hit again, by 2005 only 13 of the island only the large land birds, 83 of the medium ground finch. rare is that birds do not survive the medium to longer follow the old path mm 28 years ago to eat larger seeds to adapt to drought, but produced a significantly smaller beak trend Lots of competition with the large ground finch in the process, by eating the seeds and trying to keep a very small chance of survival. beak narrowing of the medium ground finch still not a new species, but Peter. Grant that again as long as the natural evolution of this on several occasions, maybe there will be a new species of dreams of coming out.
Galapagos finch differences exist between starting a common ancestor, evolved their own unique technique for a particular food. Another famous case occurred in a species radiation into water bodies mm Great Rift Valley lakes and rivers have brought up about 2,000 species of cichlids, which are derived from just a few ancestral species, and its evolutionary and geological time span of only a few compared to the changes of this moment. For example, the largest of these lakes, Lake Victoria, also a drop of water in 1.5 million years ago did not, and now Lai lake no less than 500 species of fish, all during this time from several species of unknown origin evolved. and to birds, as cichlid species have adapted to their different foraging habitat, such as rocky or sandy lake bed. Some species eat algae, so the fine tooth mouth, scraping and tearing plant for foodstuffs, as well as post-eating snails, they have a thick powerful jaws that can crunch crustaceans. Guess what genes are responsible for thickening of their articulate? BMP4 protein gene is encoded, that is, that the Galapagos finch beak deepening widening of the gene. the same gene, in the distant mountains and seas of the two places, fish and birds, respectively, as the same duties. to prove that all the species of Darwin believe that common, there is better evidence than this you?
adult zebra finches (who left in the red beak) in the song to teach young birds.
in the . If we told him that there is a gene called FOXP2, the human language, the normal development of song birds are critical, he must be very happy to .2001, Simon. Fisher and colleagues at the University of Oxford found that mutations in this gene can cause defects in human language. Later, he also confirmed that the FOXP2 gene in mice to learn the essential combination of fast action, without it, the brain can not form a record of this learning process the neural network. basis of this speculation, FOXP2 gene is the human need, we should declare their own ideas of the mouth, we have to learn the delicate tongue rippling action.
Then, the Berlin Free University of Constance. Schaaf found young zebra finches learn song, when somewhere in the FOXP2 gene in the brain becomes more active. Schaaf's team to a devil's cutting-edge technology, with a special virus infected finch brain, the virus carrying part of the FOXP2 gene in the reverse sequence, inhibit the natural expression of the gene. The results, in a move called up to the bird off the mark, and in mimic birds will sing out of tune mm as FOXP2 mutations in children suffering from babbling aloud, not learn to speak.
competition and environmental changes to survive the pressure like the process of creating new species, Darwin's contemporary followers have observed a clear picture. But Darwin also proposed another evolutionary impetus mm sexual selection. vision of Lake Victoria cichlids compatible with the surrounding environment: in deep water, through the rays of the red end of spectrum bias, so the cichlid visual receptors more sensitive to red light; and near the surface where they blue things more clearly. Bern University Ole. Ze Stockhausen observed, male cichlids have evolved bright body colors to attract females favor, usually in the bottom of the lake area activities to turn red, while the shallow water in becomes blue. red and blue fish seems to occur from the genetic differentiation, suggesting the formation of two separate species is.
FOXP2 gene is the key to young birds learn voice, neurobiology Home Constance. Schaff (on), if that failure of this gene, the birds will sing aloud of Hu.
If natural selection is the survival of the fittest (those who create the word philosopher He is Bert. Spencer, not Darwin), then sexual selection is the decorative parts, such as the stag horns, is in the same-sex melee, fighting for females. Others, such as the peacock tail and the like, is used to The argument put forward as said: on one side, also led to a slight mocking: the natural world that is actually active female choice of spouse, and not shy to accept the male's a romance. even the biologists to reject this theory for almost a century because they were All thoughts are used to prove the biological characteristics obtained through the evolution for the entire species, rather than individual organisms. But now we know that Darwin's guess is always correct. from fish to birds, from insects to frogs in a variety of all sorts of species, females are close to the most blatantly male fancy, invite them to have sex.
As for why females choose males look more handsome, Darwin did not make too much thinking. biologists even today a great time on this issue, because they have two equally beautiful answer. One is a simple fashion: When the number of females selected Yingwei male, other females have to follow suit, or have to worry about their son will not move home girl welcome. some Another explanation is more subtle: to grow a gorgeous big tail, but one of the male peacock is both laborious and dangerous tasks, until only the most well mm healthy male parasites, starvation, or combing focus will be detrimental to the tail feathers not the CLS. Therefore, the bright tail feathers form the so-called evolutionary biologists Best opposite sex is even a female peacock, they unknowingly passed on to future generations the best genes.
Darwin also thought, maybe it is sexual selection created a racial distinction. individual species has its own beauty standard hh within a tribe, strong men choose attractive women, average level, the more children will be nurtured, handed down many generations, it will change the whole to some extent tribal face. University of Copenhagen Hans. Yibei Ge and his colleagues announced that it has found in common among all pure-bred blue-eyed gene mutations. this place is just a mutation change in mm from the letter A into G, at 15 the long arm of chromosome. its existence hinders OCA2 gene expression, and the genes involved in eye color to darken the pigment synthesis mechanism. Ai Beige to Danish DNA with the Turks and Jordanians of DNA compared This mutation is calculated in 6000 to 10,000 years ago occurred only much later in the invention of agriculture, and the first mutation is somewhere around the Black Sea people. Darwin was on the blue eyes, perhaps have since the Neolithic farm during the child's DNA in a mere letter of a misspelled.
why this mutation was so wide spread it? no evidence that blue eyes can help the survival of mankind. perhaps because human skin has blue eyes Comparison of white, and white skin absorbs more sunlight, the synthesis of vitamin D. This is not too much to enjoy the sun from the north is particularly important because grain in their diet increasing the proportion of vitamin D levels are very low. Another On the one hand, it may be that the geographical area of the opposite sex is just a soft spot for blue eyes, with this feature it easier to many children and grandchildren. no matter which one is true, the two are nothing more than Darwin's theory of natural mm selection and sexual selection.
Interestingly, this error makes blue eyes are not part of the letter pigment gene itself, but in the vicinity of the gene expression of a control DNA. This phenomenon supports the nowadays popular in genomics and a theory in evolutionary biology: the mechanism of evolution is not only to change the genes, gene activation and also to change the way off. University of Wisconsin, Sean. Carroll said: genetic changes, but to control developmental gene regulation by different. ; soul of the Most genes are related to them is no different. It is as if writers of different books, but it is used the same set of words, nature is also not necessarily need to create new genes, new species mm as long as the operation of changing the order of genes and pattern on the line.
stands to reason scientists should be aware of this earlier. After all, not the animal's body like a machine assembled, but to growth, development, so the evolution of the growth mechanism of the process is always changing, not required to be the result of growth. In other words, there is no specific length of a giraffe neck gene, growth of their neck and head of the same gene, and mice; Perhaps these genes is only open a long time to create a longer neck. < br> As Darwin's fossils from the armadillo, who the American ostrich and inspiration to birds, he inherited the mantle of scientists have a combination of genetic research and the study of fossils to understand the history of life .2004, Neil University of Chicago. Shubin and colleagues in the Canadian Arctic found a fossils 375 million years ago, this animal just right to make up the fish and terrestrial animals, the space between. They called it fins in the terrestrial animal bone and upper arm, forearm and even the wrist-one correspondence. escape predators can climb up the shore when the mudflats.
Shubin obtained in the genetics laboratory findings are also striking. But with fossils, scientists began to study its survival inspired the world the birds, mammals and other terrestrial animals, the limbs of embryos when building the model are similar. only difference is that gene expression in fish in the open time is short. The discovery broke a long-standing misconception that land animals limbs is a major evolutionary events experienced was obtained. occur during the development, but the original old tricks again with a new routine play. knowledge of the mechanisms of genetic mess. He first considered the characteristics of biological parents would mix inherited, and later came to believe that it will get its own new features of life to future generations. He has never been in this area did not reach Bangladesh Dell's high degree of awareness, is not biological parents do not understand the mix of the various features of its heritage, its parents, grandparents and even the ancestors of all of the above characteristics, in order to select the reorganization of certain laws result from generation to generation. Mendelian inheritance laws explained paper published in 1866 in Moravia, a membership journal unknown nationality, this time from the did not cause any concern. Mendel rough priest lives for the better, that the significance of the findings until many years after his death was only the world know. but his legacy as Darwin, as unprecedented in modern glow with vitality.
