Hao Yichun

Hao Yichun is a astronomy 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 Hao Yichun rather than just read about it. In short: Hao Yichun (Chinese: 郝诒纯; 1920–2001) was a Chinese paleontologist and a member of the Chinese Communist Party. She is known as a pioneer in bringing paleontology to China, co-authoring the first Chinese textbooks in paleontology and micropaleontology.

Key takeaways

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

Reference excerpt

Hao Yichun (Chinese: 郝诒纯; 1920–2001) was a Chinese paleontologist and a member of the Chinese Communist Party. She is known as a pioneer in bringing paleontology to China, co-authoring the first Chinese textbooks in paleontology and micropaleontology. She made significant contributions to stratigraphy, petroleum exploration, and palaeoceanography.

Life Hao was born in the Wuchang District of Hubei Province, China. She was first enrolled in the history department of National Southwestern Associated University, China, but eventually transferred to the geology, climate, and geography department, graduating in 1943. She went on to do postgraduate studies at Tsinghua University, graduating in 1946. From 1946 to 1952, she taught at Beijing University, later becoming an associate professor at the Beijing Geological Institute and the Beijing Branch of Wuhan Geological Institute. In 1980, she became an academician in the Academic Division of Earth Sciences of the Chinese Academy of Sciences. She died from cancer in Beijing in 2001.

Research Hao and her research group established the standard stratigraphy for northeast and southwest China. Her work on micropalaeontology, especially Foraminifera, was important to the national exploration and exploitation of marine energy resources. She co-wrote the first Chinese textbook on paleontology with Yang Zunyi and Chen Guoda in 1956.

Major publications "Paleontology Textbook" (1956) "Cretaceous–Tertiary Ostracods of the Songliao Plain" "Middle Jurassic–Tertiary Strata and Ostracod and Charophyte Fossils of the Minhe Basin, Xining" "Late Cretaceous–Tertiary Strata and Foraminifera of the Western Tarim Basin" "Cretaceous System of China" "Foraminifera"

Career in the Chinese Communist Party Hao was heavily involved in the Chinese Communist Party, first joining the party in 1936, which was retroactively officially recognized in 1979. Prior to her undergraduate studies, she was part of student movements and organizations, including the Chinese National Liberation Vanguard (Minxian). She was especially active in the scientist-based Jiusan Society, becoming vice chairperson in 1983. Same year, she was recognized as a National March 8th Red-Banner Holder. Her history in the party included: member of the Standing Committee of the Chinese People's Political Consultative Conference, member of the Standing Committee of the People's Congress of China, vice chairwoman of the Standing Committee of the People's Congress of Beijing, and vice chairwoman of the Women's Federation of China. In 1993, commissioned by the Standing Committee of the National People's Congress, she represented China in the Asian Forum of Parliamentarians on Population and Development of the United Nations Population Fund (AFPPD), later becoming the executive vice-chairperson of the AFPPD. Same year, she organized the 10th International Conference on Population and Development in Asia, where she presented a speech on the relationship between activist movements for Chinese women rights and the Chinese population.

Legacy In 2020, the China University of Geosciences (Beijing) hosted the 100th anniversary memorial conference.

Worked examples

Example 1 — a first encounter with Hao Yichun

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

In research: Hao Yichun appears in astronomy 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 Hao Yichun 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: Hao Yichun is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 2001 deaths, All-China Women's Federation people, so understanding it makes those chapters shorter.
In everyday life: Look for Hao Yichun 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.
