How do you teach important subjects to others?

Occam's razor is a principle in physics that, in philosophical terms, means that the simplest explanations are the best.

The following quote is often attributed to Albert Einstein:

'If you can't explain it simply, you don't understand it well enough.'

We should teach others as if we are teaching a five-year-old.

If the basic questions underlying a complex problem are explained succinctly, the teacher has already conveyed the desired message.

This teaching method must be followed by the multiple-choice question-and-answer method, which involves explaining why the wrong options are wrong in the first place.

In this way, the learner's foundation would strengthen, and the correct answer would be engraved in his memory.

But, how to make the topic interesting so the student is curious?

This involves invoking the learner's emotions.

It is incorrectly assumed that logic is the only factor in understanding complex subjects such as physics and coding.

Strong emotions make a more profound impact than pure logic.

So, a combination of emotions leading to logical thinking has to be strived for. For example, storytelling by invoking history, fiction, and real-life examples.
