Tracianne Neilsen

Tracianne Neilsen 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 Tracianne Neilsen rather than just read about it. In short: Tracianne Beesley "Traci" Neilsen is an American physicist whose research concerns the use of machine learning in acoustics for source localization and source characterization, both in undersea applications and for aircraft. She is a professor at Brigham Young University (BYU) and associate chair of the BYU Department of Physics and Astronomy.

Key takeaways

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

Reference excerpt

Tracianne Beesley "Traci" Neilsen is an American physicist whose research concerns the use of machine learning in acoustics for source localization and source characterization, both in undersea applications and for aircraft. She is a professor at Brigham Young University (BYU) and associate chair of the BYU Department of Physics and Astronomy.

Education and career Neilsen was a physics major at BYU, graduating in 1992. She went to the University of Texas at Austin for graduate study in physics, and completed a Ph.D. there in 2000. Her dissertation, Normal Mode Extraction and Environmental Inversion from Underwater Acoustic Data, was supervised by Takeshi Udagawa and Evan K. Westwood. She continued at the University of Texas at Austin for postdoctoral research from 2000 to 2003, and as a part-time research scientist from 2003 to 2007, while taking a part-time adjunct faculty position at BYU from 2004 to 2010. In 2010 she shifted to a regular-rank assistant professorship at BYU; she was promoted to associate professor in 2018 and full professor in 2024. She has also served the Acoustical Society of America as chair of the Women in Acoustics Committee from 2018 to 2021 and as Chair of the Committee on Outreach and Education beginning in 2024.

Recognition Neilsen was elected as a Fellow of the Acoustical Society of America in 2022, "for applications of machine learning to inverse problems in ocean acoustics".

Worked examples

Example 1 — a first encounter with Tracianne Neilsen

Start with the simplest possible case. Write down what Tracianne Neilsen 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 Tracianne Neilsen 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 Tracianne Neilsen 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 Tracianne Neilsen

In research: Tracianne Neilsen 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 Tracianne Neilsen 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: Tracianne Neilsen is common in secondary-school and first-year university syllabi. It links to neighbouring topics American physicists, American women physicists, Brigham Young University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Tracianne Neilsen 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.
