Wen Ho Lee

Wen Ho Lee is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wen Ho Lee rather than just read about it. In short: Wen Ho Lee (Chinese: 李文和; pinyin: Lǐ Wénhé; born December 21, 1939) is a Taiwanese-American nuclear scientist and mechanical engineer who worked for the University of California at the Los Alamos National Laboratory in New Mexico. He created computerized simulations of nuclear explosions for the purposes of scientific inquiry, as well as for improving the safety and reliability of the U.S. nuclear arsenal.

Key takeaways

  • Wen Ho Lee belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Wen Ho Lee to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Wen Ho Lee from memory before moving on to harder problems.

Reference excerpt

Wen Ho Lee (Chinese: 李文和; pinyin: Lǐ Wénhé; born December 21, 1939) is a Taiwanese-American nuclear scientist and mechanical engineer who worked for the University of California at the Los Alamos National Laboratory in New Mexico. He created computerized simulations of nuclear explosions for the purposes of scientific inquiry, as well as for improving the safety and reliability of the U.S. nuclear arsenal. A federal grand jury indicted him on charges of stealing secrets about the U.S. nuclear arsenal for the People's Republic of China (PRC) in December 1999. After federal investigators were unable to prove these initial accusations, the government conducted a separate investigation. Ultimately it charged Lee only with improper handling of restricted data, one of the original 59 indictment counts, a felony count. He pleaded guilty as part of a plea settlement. Lee filed a civil suit that was settled. In June 2006, he received $1.6 million from the federal government and five media organizations as part of a settlement for leaking his name to the press before any charges had been filed against him. Federal judge James A. Parker eventually apologized to Lee for denying him bail and putting him in solitary confinement. He excoriated the government for misconduct and misrepresentations to the court.

Early life Wen Ho Lee was born on December 21, 1939, to a Hoklo family in Taiwan during Japanese rule. He graduated from Keelung High School in the northern part of the island in 1959, after which he attended National Cheng Kung University in Tainan, where he graduated with a Bachelor of Science in mechanical engineering in 1963. In My Country Versus Me, Lee describes life as being harsh. His father died when Lee was very young. His mother suffered from asthma and eventually committed suicide so that she would not 'burden' the family. He was a young boy in Taiwan when Republic of China (ROC) forces violently suppressed the February 28 Incident of 1947. Taiwan was placed under martial law; his brother died when he was a conscript and his commanding officers allegedly would not allow him to take medicine. Lee overcame steep odds. He had what he describes as a wonderful teacher in the 6th grade who encouraged his intellectual abilities. Eventually, he made his way to university, where he became interested in fluid dynamics and studied mechanical engineering.

Graduate education and career Lee came to the United States in 1965 to continue his studies in mechanical engineering at Texas A&M University. He received his doctorate in mechanical engineering with specialization in fluid mechanics in 1969 and was naturalized as a U.S. citizen in 1974. He was employed at industrial and government research firms before he moved to New Mexico in 1978. He worked as a scientist in weapons design at Los Alamos National Laboratory, in applied mathematics and fluid dynamics, from that year until 1999. He created simulation software for nuclear explosions, which were used to gain scientific understanding and help maintain the safety and reliability of the US nuclear weapons arsenal.

Government investigation Lee was publicly named by United States Department of Energy officials, including Secretary of Energy Bill Richardson, as a suspect in the theft of classified nuclear-related documents from Los Alamos. Richardson was criticized by the Senate for his handling of the espionage inquiry because he had not testified sooner before Congress. Richardson was less than truthful in his response by saying that he was waiting to uncover more information before speaking to Congress. On December 10, 1999, Lee was arrested, indicted on 59 counts, and jailed in solitary confinement without bail for 278 days. On September 13, 2000, he accepted a plea bargain from the federal government. Lee was released on time served after the government's case against him could not be proven. Part of his defense rested on a graymail strategy, which tried to compel prosecutors to release large amounts of classified material related to nuclear weapons. He was ultimately charged only with one count of mishandling sensitive documents, which did not require pre-trial solitary confinement. The other 58 counts were dropped. President Bill Clinton issued a public apology to Lee over his treatment by the federal government during the investigation. Lee filed a civil lawsuit to gain the names of public officials who had leaked his name to journalists before charges had been filed against him. It raised issues, similar to those in the Valerie Plame affair, of whether journalists should have to reveal their anonymous sources in a court of law. Lee's lawsuit was settled by the federal government in 2006 just before the Supreme Court was set to decide whether to hear the case. The federal judge who heard the case during an earlier appeal said that "top decision makers in the executive branch...have embarrassed our entire nation and each of us who is a citizen."

Worked examples

Example 1 — a first encounter with Wen Ho Lee

Start with the simplest possible case. Write down what Wen Ho Lee claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wen Ho Lee before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wen Ho Lee ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wen Ho Lee

In research
Wen Ho Lee appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Wen Ho Lee in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Wen Ho Lee is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, American people of Chinese descent, Espionage in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Wen Ho Lee outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
