Hogan Yu

Hogan Yu 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 Hogan Yu rather than just read about it. In short: Hua-Zhong "Hogan" Yu (于化忠) is presently a professor of materials and analytical chemistry at Simon Fraser University in metro Vancouver, Canada, where he leads a research laboratory working on Surfaces and Materials for Sensing. He is also an associate editor for Analyst, the journal for Analytical and Bioanalytical Sciences from the Royal Society of Chemistry in UK, and an adjunct professor in the College of Biomed…

Key takeaways

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

Reference excerpt

Hua-Zhong "Hogan" Yu (于化忠) is presently a professor of materials and analytical chemistry at Simon Fraser University in metro Vancouver, Canada, where he leads a research laboratory working on Surfaces and Materials for Sensing. He is also an associate editor for Analyst, the journal for Analytical and Bioanalytical Sciences from the Royal Society of Chemistry in UK, and an adjunct professor in the College of Biomedical Engineering, Taiyuan University of Technology in Shanxi, China.

Education Born and raised in countryside China, Yu obtained his B.Sc. (Chemistry) from Shandong University in 1991 at an age of 20. He then received his joint M.Sc. from Shandong University and Dalian Institute of Chemical Physics (Chemical Physics) in 1994, and his Ph.D. from Peking University (Materials Chemistry, with Prof. Zhong-Fan Liu) in 1997. He did his postdoctoral research with Nobel Laureate Ahmed Zewail and electrochemist Fred Anson at the California Institute of Technology from 1997 to 1999.

Career After short stays at NRC and Acadia University, Yu was appointed to the Department of Chemistry at Simon Fraser University in 2001 as an assistant professor and promoted to a tenured full professor in 2009. He is now a principal investigator of the CFI-funded Centre for Nanomaterials and Microstructures (4D LABS) and an associate member of the Department of Molecular Biology and Biochemistry, both at SFU. Yu has been pursuing his cutting-edge research on solving fundamental problems that have direct impact on applied analytical science and technology. His innovation of adapting mobile electronics (office scanners, disc players, and now smartphones) for portable molecular analysis and his contribution to the de novo construction of ultrasensitive electronic biosensors for disease markers, lead to the possibility of performing many quantitative chemical analysis on-site and biomedical diagnostic tests at point-of-care settings. He has published more than 160 peer-reviewed articles and holds/filed 14 national/international patents.

Lash Miller Award (ECS Canadian Section) 2012 Tajima Prize (ISE) 2015 W.A.E. McBryde Medal (CSC) 2021 Fellow, Royal Society of Chemistry

Worked examples

Example 1 — a first encounter with Hogan Yu

Start with the simplest possible case. Write down what Hogan Yu 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 Hogan Yu 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 Hogan Yu 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 Hogan Yu

In research: Hogan Yu 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 Hogan Yu 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: Hogan Yu is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Simon Fraser University, Analytical chemists, Educators from Shandong, so understanding it makes those chapters shorter.
In everyday life: Look for Hogan Yu 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.

Frequently asked questions

What is Hogan Yu in simple terms?

Why does Hogan Yu matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Hogan Yu?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
