Junseok Chae

Junseok Chae 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 Junseok Chae rather than just read about it. In short: Junseok Chae (Korean: 채준석; died 25 March 2020) was a South Korean engineer and academic administrator specialized in microelectromechanical systems. He was a professor at the Arizona State University (ASU) School of Electrical, Computer, and Energy Engineering and associate dean of research and innovation at ASU Ira A.

Key takeaways

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

Reference excerpt

Junseok Chae (Korean: 채준석; died 25 March 2020) was a South Korean engineer and academic administrator specialized in microelectromechanical systems. He was a professor at the Arizona State University (ASU) School of Electrical, Computer, and Energy Engineering and associate dean of research and innovation at ASU Ira A. Fulton Schools of Engineering.

Life Chae completed a B.S. in metallurgical engineering at Korea University in 1998. He earned a M.S. (2000) and Ph.D. (2003) in electrical engineering and computer science at University of Michigan. His dissertation was titled High-Sensitivity, Low-Noise, Multi-Axis Capacitive Micro-Accelerometers. Chae's doctoral advisor was Khalil Najafi. He was a postdoctoral researcher at the Engineering Research Center for Wireless Integrated Microsystems. Chae joined Arizona State University (ASU) in 2005 as an assistant professor of engineering. On August 15, 2017, Chae became associate dean of research and innovation at ASU Ira A. Fulton Schools of Engineering. He was a professor in the School of Electrical, Computer, and Energy Engineering. Chae received a National Science Foundation CAREER Award on MEMS protein sensor array.

Murder Chae went missing after work on 25 March 2020. Police officers in Shreveport, Louisiana contacted Maricopa County Sheriff's Office on 30 March after locating three individuals in possession of Chae's vehicle. Police officers found that Chae was killed in Phoenix, Arizona near the intersection of 7th Street and Arizona State Route 74. On 15 July 2020, police charged 18-year-old Javian Ezell and 18-year-old Gabrielle Austin with first-degree murder, armed robbery, and theft of means of transportation. Chae's remains were found on 17 July 2020 in the Northwest Regional Landfill. He was bludgeoned to death. Gabrielle Austin entered a plea of guilty to charges of murder in the second degree and abandoning or concealing a dead body on November 2, 2021; subsequently, her co-defendant, Javian Ezell, also entered his plea of guilty to the same charges, on February 25, 2022. They were sentenced on March 25, 2022, in the Maricopa Superior Court. Austin was sentenced to 20 years incarceration for the murder, while Ezell was sentenced to 25 years incarceration.

Worked examples

Example 1 — a first encounter with Junseok Chae

Start with the simplest possible case. Write down what Junseok Chae 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 Junseok Chae 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 Junseok Chae 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 Junseok Chae

In research: Junseok Chae 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 Junseok Chae 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: Junseok Chae is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020 deaths, 2020 murders in the United States, 21st-century South Korean scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Junseok Chae 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.
