On March 26, 1999, I became a new staff member of the Los Alamos National Laboratory. I co

mmitted the rest of my scientific future there despite the allegations of espionage leveled at one of its weapons scientists, Wen Ho Lee, who, notably, has never been and may never be officially charged. I valued the accomplishments of its distinguished scientists and was confident its able leaders would receive the political support they needed from Washington to cope with the potential damage to its programs arising from the scandal.

But in the months since then that support has come into question—and the damage has become real. Washington's reaction to the incident has created an atmosphere of suspicion, which, coupled with efforts to restrict scientific interchange and reduce funds for key research, threaten the essence of the lab—its ability to provide the kind of science-based security that has made it a national treasure.

Los Alamos burst upon the national consciousness on Aug 6, 1945, the day it was announced that the atomic weapon dropped on Hiroshima had been developed by scientists working at the lab under the direction of Robert Oppenheimer. The secret of their success was an almost magical mix of three key ingredients: the quality and dedication of the researchers, an open scientific environment that promote collaboration and Oppenheimer's brilliant leadership.

That excellence, openness and leadership have largely been maintained in the ensuing 54 years under the enlightened management of the University of California. During the cold war, when national security demanded that we have a competitive edge over the Soviets in nuclear weapons and weapons-related research, Los Alamos led the way. When it became evident that science-based national security depended on world leadership in science, the lab rose to the challenge. It developed an outstanding program to attract the best young researchers and established world-class trans-disciplinary centers for pure and applied scientific research. Indeed, what brought me to Los Alamos was the new Institute for Complex Adaptive Matter, established to work on what promises to be the most exciting science of the new millennium— the search for the higher organizing principles in nature that govern emergent behavior. in matter.

But in the past six months members of Congress and the Washington bureaucracy have put the scientific environment at Los Alamos seriously at risk. With the laudable goal of improving the security of classified research, they have attempted to impose inefficient micromanagement strategies while decreasing funding for vital research. As Sen. Pete Domenici, Republican of New Mexico, wrote recently to a Horse colleague, "The House action is irresponsible." The damage, he said, "would be as serious and more assured than the suspected damage that may have been caused by Wen Ho Lee."

Some of that damage has already been done. By my count there's been a 60 percent drop in the number of top researchers accepting postdoctoral fellowships at the lab. Promising young staffers are leaving for university and industry jobs, while leading university scientists have refused to be considered for key administrative positions at Los Alamos. Then, too, there's the loss of the young scientist from China who wanted to come to the lab to work with me this fall. Despite his outstanding record of scientific publication and glowing letters of recommendation, I felt obligated to discourage him from entering the postdoctoral competition. In the current atmosphere, I felt his every move would be monitored. But I wonder whether we've lost a chance to attract to America a major contributor to science—and a potential Nobel laureate.

Washington must never forget that science is done by scientists, not by computers. It is vital to build security barriers in physical space and cyberspace to protect classified information. But science is not don

A.he appreciated its scientific environment

B.he esteemed its distinguished scientists and treasured their accomplishments

C.it obtained support from Washington

D.its leaders were all able to cope with the potential damage to its programs.

The Chinese written language is of conservation type that assigns a single distinctive symbol, or character, to each word of the vocabulary. Knowledge of 3000 to 4000 characters is needed to read newspapers, and a large dictionary contains more than 40,000 characters (arranged according to sound or form). Like other scripts of ancient origin, Chinese is derived from picture writing. It grew into a word-by-word representation of language when it was discovered that words too abstract to be readily pictured could be indicated by their sound rather than their sense. Unlike other scripts, however, Chinese still works pictographically as well as phonetically. Moreover, its sound indications have not been adapted to changes of pronunciation but have remained the key of pronunciation of 3000 years ago. The building blocks of the system are several hundred pictographs for such basic words as man, horse, and axe. In addition, expanded, or compound, pictographs exist. For example, a symbol of this type representing man carrying grain means "harvest," and thus "year"(nian).

Phonetic loans are pictographs of concrete words borrowed to indicate abstract words of the same or similar sound. The principle here is that of the rebus, or visual pun. Thus, the pictograph for dustpan (ji) was borrowed for this, his, her, its (qi or ji). Through the Zhou period (11th century to 3rd century BC) many characters had such a dual use. If at that time the scribes had agreed that only the "dustpan" pictograph would stand for any syllable pronounced ji, they would have discovered the principle of the phonetic syllabary, precursor of the alphabet. Because of the great number of homonyms in Chinese, however, scribes instead retreated to picture writing. The picture of the dustpan came to be used exclusively for his, her, its. In the rarer instances when scribes actually meant to refer to a dustpan, however, they avoided ambiguity by employing a compound symbol in which "dustpan" had added to it the pictograph for "bamboo", representing the material from which dustpans were made. This process for reducing the ambiguity of phonetic loans became in time a process by which any pictograph, borrowed for its sound, could be joined to any other chosen to indicate the meaning, forming a phonetic compound. Thus, "dustpan," with the addition of "earth" instead of "bamboo," indicated ji, " base, foundation. " Today simple and compound pictographs continue to be used for some of the most basic vocabulary — home, mother, child, rice, fare. Perhaps 95 percent of the words in the dictionary are written with phonetic compounds, however.

To express modem concepts, Chinese generally invents equivalents from its native stock of meaningful syllables or renders such terms in phonetic spelling. Thus, chemistry is expressed in Chinese as "study of transformations. "

Shihuangdi (Shih-huang-ti), first emperor of a unified China, suppressed many regional scripts and enforced a simplified, standardized writing called the Small Seal. In the Han Dynasty (206BC-AD220) this developed into the Clerical, Running, Draft, and Standard scripts. Printed Chinese is modeled on the Standard Script, Cursive or rapid writing (the Running and Draft scripts) introduced many abbreviated characters used in artistic calligraphy and in commercial and private correspondence, but it was long banned from official documents. The printing of abbreviated characters is still forbidden in Taiwan but has become the normal practice in the People's Republic of China.

If one wants to read newspapers, knowing______words would be the minimum requirement.

A.1,000

B.2,000

C.3,000

D.40,000
