Teaching as the Ultimate Test of Understanding
In the world of engineering and knowledge,
true strength is not about defeating others.
True strength lies in how deeply you understand your field.
Do you truly understand the principles?
Can you explain them clearly?
Can you see through the essence of the problem?
This is why I strongly advocate the Feynman Technique.
At its core, it is a simple but powerful learning loop:
First, study a topic.
Second, ask yourself questions:
What do I still not understand? Why does this work?
Third, try to explain the idea in the simplest and clearest way.
Fourth, teach it to someone else.
When you begin explaining, you will inevitably stumble.
Those moments of hesitation reveal exactly where your understanding is incomplete.
Then you return to the material and refine your understanding.
This creates a closed loop of learning.
Through this loop, knowledge becomes truly yours.
But many people ask:
What if there is no one around to teach?
My answer is simple:
Record a video and explain the topic.
When you try to clearly explain a concept in a video,
you are effectively testing your own understanding.
If you can explain it clearly,
you have likely grasped the core of the idea.
More importantly, your audience will ask questions.
Those questions will reveal the gaps in your understanding,
and the learning loop begins again.
In this sense, social media is not merely a broadcasting platform.
It is a powerful tool for learning.
By sharing what you learn, you:
• deepen your understanding
• build your digital assets
• accumulate influence and audience
• connect with the world
That is why I often encourage engineers and learners:
If you want to truly understand something,
teach it to the world.
在工程與知識的世界裡，
真正的強，從來不是打敗別人。
真正的強，是你對自己所在領域的理解有多深。
你是否真正理解它的原理？
你是否能夠清楚地解釋它？
你是否能夠看透問題的本質？
這也是我一直推崇 費曼學習法（Feynman Technique） 的原因。
它其實是一個非常簡單但強大的循環：
第一步，學習一個主題。
第二步，對自己提問：
哪些地方我還不理解？為什麼是這樣？
第三步，用最簡單清楚的方式解釋它。
第四步，試著把它教給別人。
當你開始解釋時，你會發現自己卡住的地方。
這些卡住的地方，就是你還沒有真正理解的地方。
然後你再回去重新理解它。
於是，你形成了一個學習的閉環。
透過這個循環，你可以真正把一個知識吃透。
但很多人會問：
如果身邊沒有學生、沒有可以教的人，怎麼辦？
我的建議是：
把你的理解錄成影片。
當你嘗試在一個影片裡清楚地解釋一個 Topic，
其實就是在測試自己是否真的理解它。
如果你能夠清楚地講明白，
那代表你已經初步掌握了這個知識。
更重要的是，
觀眾會提出問題。
這些問題會再次幫助你發現
哪些地方你其實還沒有完全理解。
於是，學習的循環再次開始。
因此，自媒體不只是傳播工具。
它其實是一個非常強大的學習工具。
透過分享，你會：
• 更深地理解知識
• 建立自己的數位資產
• 累積內容與影響力
• 與世界建立連結
所以我一直鼓勵工程師與學習者：
如果你想真正理解一個領域，
那就試著把它講給世界聽。
