Founder, Owner & Editor of Explained How
Duc Nguyen is a Vietnamese founder, editor, and explanatory writer who researches and analyzes how things work.
He is the founder and owner of Explained How, an independent educational publication built around one central question:
How does it actually work?
Rather than focusing on only one narrow subject, Duc explores the mechanisms behind a wide range of systems, technologies, natural phenomena, living things, machines, and everyday objects.
His work may move from animal senses and weather to aircraft, artificial intelligence, the Internet, refrigeration, transportation, energy systems, or the human body.
The subjects may change.
The method does not.
For Duc, understanding something means going beyond its definition and examining what happens between the input and the outcome.
About Duc Nguyen
Duc Nguyen is from Vietnam and is the founder, owner, primary editor, and primary explanatory writer behind Explained How.
His work is driven by curiosity about the systems people encounter every day but do not always fully understand.
That curiosity can begin with a simple question:
- How do birds fly?
- How does rain form?
- How does the human heart pump blood?
- How does a refrigerator keep food cold?
- How does radar detect an object?
- How does a jet engine produce thrust?
- How does Wi-Fi carry information?
- How does artificial intelligence process input?
- How does the Internet move data around the world?
Although these subjects may belong to very different fields, Duc approaches them through the same editorial lens:
What is happening inside the system, and why does one step cause the next?
That question is at the center of Explained How.
What Duc Does at Explained How
As founder and editor, Duc is responsible for the overall editorial direction of Explained How.
His work includes:
- researching new subjects;
- identifying the core mechanism behind a question;
- finding authoritative sources;
- comparing multiple explanations;
- reconstructing cause-and-effect relationships;
- identifying important assumptions and limitations;
- developing article structures;
- reviewing technical explanations for clarity;
- maintaining Explained How’s editorial standards;
- developing concepts for explanatory visuals;
- reviewing and correcting published content when necessary.
The goal is not simply to collect information about a subject.
It is to turn that information into an explanation a curious non-specialist can understand.
A Mechanism-First Approach
Explained How follows what Duc calls a Mechanism-First approach.
Whenever useful, a system can be examined through five basic stages:
INPUT → PROCESS → OUTPUT → FEEDBACK → LIMITS
Input
What enters the system?
This might be:
- energy;
- information;
- matter;
- force;
- money;
- biological signals;
- electrical signals;
- human decisions.
Process
What happens inside the system?
Which components, forces, reactions, protocols, rules, or participants transform the input?
Output
What result does the process create?
Feedback
What regulates, monitors, corrects, or changes the process?
Limits
When does the mechanism change, become inefficient, fail, or stop applying?
This framework is not forced onto every article.
It is a way of making sure an explanation goes beyond naming components and actually shows how they interact.

These are areas of research and editorial coverage, not claims that Duc holds professional credentials in every field.
Research Before Authority
Duc does not claim to be an expert in every subject Explained How covers.
That distinction is important.
No single person can realistically be a specialist in physics, biology, engineering, medicine, artificial intelligence, economics, aviation, weather, and every other subject the publication may explore.
Instead, Duc’s role is to research carefully and explain responsibly.
Depending on the topic, research may involve:
- government publications;
- scientific agencies;
- official technical documentation;
- standards organizations;
- academic institutions;
- peer-reviewed research;
- engineering specifications;
- manufacturer technical documentation;
- legislation;
- regulatory documents;
- recognized professional organizations;
- reputable specialist publications.
Where practical, primary and authoritative sources are preferred over recycled summaries.
The aim is to trace important claims as close as possible to the underlying evidence.
How Duc Approaches a Topic
Research usually begins by identifying the actual mechanism the reader needs to understand.
That means asking questions such as:
What happens first?
What causes the next step?
Which component is actually responsible for the result?
What regulates the process?
What changes when conditions change?
Where can the system fail?
What part of the mechanism is commonly oversimplified?
Duc then works backward and forward through the process until the causal chain makes sense.
The purpose is not to include everything ever written about a subject.
It is to include the information necessary to understand how the system works.
The Part Most Explanations Miss
One of Duc’s recurring research questions is:
What important part of this mechanism is usually left out?
Sometimes the missing piece is:
- a causal step;
- a feedback loop;
- a necessary condition;
- a system limitation;
- a trade-off;
- a misleading analogy;
- a distinction between two processes people often confuse.
For example, a simplified explanation of GPS might say:
Satellites tell your phone where it is.
That is convenient, but incomplete.
A more accurate explanation is that GPS satellites continuously transmit precisely timed signals, and the receiver uses those signals to calculate its own position.
That distinction changes the reader’s mental model.
Finding these kinds of distinctions is an important part of the Explained How approach.
Clarity Without Distortion
Duc writes primarily for curious readers who may not have specialist training.
That does not mean avoiding technical terminology.
When a technical term is necessary for accuracy, Explained How uses the correct term and explains it in plain language.
The goal is not to make every topic sound simple.
The goal is to make complicated mechanisms understandable without making them wrong.
Analogies may be used when they help, but they are not substitutes for the real mechanism.
When an analogy has important limitations, those limitations should be explained.
What Duc Does Not Claim
Transparency is part of Explained How’s editorial model.
Unless clearly stated and supported by actual work, Duc does not claim that he or Explained How:
- performed laboratory experiments;
- conducted original scientific research;
- personally tested a product;
- performed clinical studies;
- collected proprietary customer data;
- performed engineering measurements;
- gathered private datasets;
- personally witnessed an event being described;
- holds professional qualifications that have not been disclosed and verified.
Research-based explanations should remain research-based explanations.
Explained How does not turn research into fictional first-hand experience.
Accuracy and Uncertainty
Not every subject has a perfectly simple or completely settled answer.
Duc aims to distinguish among:
- established facts;
- generally accepted explanations;
- technical models;
- estimates;
- interpretations;
- disputed claims;
- unknowns.
If reliable evidence is uncertain, incomplete, or contested, the language of the article should reflect that uncertainty.
Explained How would rather present a qualified answer than create false confidence.
High-Stakes Topics
Some topics require a higher level of editorial care.
These may include:
- health;
- medicine;
- financial decisions;
- investments;
- legal issues;
- public safety;
- elections;
- government benefits.
For these subjects, Explained How prioritizes authoritative sources and applies a higher research threshold.
When professional review is necessary and available, the reviewer should be clearly identified.
Explained How content is educational and informational.
It is not individualized medical, legal, financial, or other professional advice.
Editorial Responsibility
As founder and primary editor, Duc is responsible for maintaining Explained How’s editorial direction and standards.
These standards include:
- sourcing;
- factual accuracy;
- authorship transparency;
- research methodology;
- corrections;
- AI-assisted workflows;
- commercial independence;
- explanatory clarity.
Explained How documents these standards publicly so readers can understand how its content is created.

AI-Assisted Tools
Duc may use AI-assisted tools during parts of the editorial workflow.
These tools may help with tasks such as:
- organizing research;
- identifying terminology;
- generating preliminary outlines;
- identifying questions requiring verification;
- language editing;
- formatting;
- developing visual concepts.
AI output is not treated as factual evidence merely because it sounds convincing.
Important factual claims should ultimately be checked against appropriate sources.
Explained How does not knowingly use AI to fabricate:
- sources;
- studies;
- experts;
- quotations;
- statistics;
- technical specifications;
- credentials;
- URLs.
Editorial responsibility remains with Explained How.

Duc Nguyen and Explained How on YouTube
Duc is also the creator behind the Explained How YouTube channel.
The channel follows the same editorial mission as the website:
Explain how things actually work.
Video allows Explained How to visualize mechanisms that can be difficult to communicate through text alone.
These may include:
- movement;
- flows;
- component interactions;
- sequences;
- scale;
- cross-sections;
- cause-and-effect relationships.
The website and YouTube channel therefore complement each other.

From Vietnam to a Global Audience
Duc Nguyen is Vietnamese.
Explained How is primarily written for an international English-speaking audience and uses American English for most English-language content.
The subjects explored by Explained How are not limited by geography.
Natural phenomena, physical mechanisms, biological processes, machines, technology, and many everyday systems operate across national boundaries.
The goal is to explain these subjects in language that curious readers around the world can understand.
Why Duc Created Explained How
Explained How grew from a simple idea:
Knowing what something is does not necessarily mean understanding how it works.
A person may know that:
- an engine burns fuel;
- a refrigerator uses refrigerant;
- Wi-Fi uses radio waves;
- GPS uses satellites;
- artificial intelligence uses neural networks;
without understanding the mechanism connecting those facts to the final result.
Explained How focuses on that missing middle.
Instead of stopping at:
What is it?
the publication asks:
What happens inside it?
Why does that happen?
What controls the process?
What are the limits?
Those questions define Duc’s work at Explained How.
A Note From Duc Nguyen
I created Explained How because I believe that understanding becomes much easier once you can see the mechanism behind the result.
My goal is not to pretend that every complicated subject has a simple answer. It is to research the process carefully, identify the relationships that matter, and explain them clearly enough that a curious reader can build a useful mental model.
The subjects may range from animals and weather to machines, aircraft, artificial intelligence, or the Internet.
What connects them is always the same question:
How does it work?
— Duc Nguyen
