Xiangzhong Yang

Xiangzhong Yang is a biology 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 Xiangzhong Yang rather than just read about it. In short: Xiangzhong "Jerry" Yang (simplified Chinese: 杨向中; traditional Chinese: 楊向中; pinyin: Yáng Xiàngzhōng; July 1959 – 5 February 2009) was a Chinese-American biotechnology scientist, and stem cell research advocate. In 1999 he was credited with creating the first cloned farm animal in the United States – a cow called "Amy".

Key takeaways

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

Reference excerpt

Xiangzhong "Jerry" Yang (simplified Chinese: 杨向中; traditional Chinese: 楊向中; pinyin: Yáng Xiàngzhōng; July 1959 – 5 February 2009) was a Chinese-American biotechnology scientist, and stem cell research advocate. In 1999 he was credited with creating the first cloned farm animal in the United States – a cow called "Amy". Born on July 31, 1959, and raised in Wei County, Handan, Hebei, China, Yang attended Beijing Agricultural University (currently China Agricultural University). Upon graduation, he took the entrance exam for graduate study and ranked number one among all applicants in his field. He was therefore awarded a prestigious scholarship from the Ministry of Agriculture to study in the US. He emigrated to the United States in 1983 where he received his PhD under Robert Foote in 1991. Yang became a research faculty member at Cornell University and received multiple grants from the Cornell Biotechnology Center and Easter AI (Genex; http://genex.crinet.com/). In 1996 he joined the faculty at the University of Connecticut as an associate professor, and in 2001, was appointed founding director of the University's Center for Regenerative Biology. In November 2017 Yang was honored with the naming of the street that leads to the University of Connecticut Dairy Bar from Route 195 as Jerry Yang Road. That same road is the location of the Agricultural Biotechnology Laboratory, where Yang performed countless hours of research that brought international fame to the University University Honors Memory of Research Great Jerry Yang. In 1996 Yang was first diagnosed with salivary gland adenocarcinoma, a condition that would eventually claim his life. On February 5, 2009, he died at the Brigham and Women's Hospital in Boston, Massachusetts, aged 49. An obituary was published by the scientific magazine Nature.

Worked examples

Example 1 — a first encounter with Xiangzhong Yang

Start with the simplest possible case. Write down what Xiangzhong Yang claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Xiangzhong Yang 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 Xiangzhong Yang 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 Xiangzhong Yang

In research: Xiangzhong Yang appears in biology 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 Xiangzhong Yang 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: Xiangzhong Yang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, 2009 deaths, 20th-century American biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Xiangzhong Yang 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.
