I read this essay just before.

[Situation 1]
...
학문에서 진실을 탐구하는 행위는 논리로 이루어진다. 진실을 탐구하는 행위라 하더라도 논리화되지 않은 체험에 의지하거나 논리적 타당성이 입증되지 않는 사사로운 확신을 근거로 한다면 학문이 아니다. 예술도 진실을 탐구하는 행위의 하나라고 할 수 있으나 논리를 필수적인 방법으로 사용하지는 않으므로 학문이 아니다.
...
논리를 어느 정도 신뢰할 수 있는가 의심스러울 수 있다. 논리에 대한 불신을 아예 없애는 것은 불가능하고 무익하다. 논리를 신뢰할 것인가는 개개인이 자유롭게 선택할 수 있는 기본권의 하나라고 해도 무방하다. 그러나 학문은 논리에 대한 신뢰를 자기 인생관으로 삼은 사람들이 독점해서 하는 행위이다.

The last sentence of first graph makes me regret that I said in front of my friend.
I told him while discussing his concerns which made him unconfortable thses days.
...
Minhee : "Is it possible that people love someone who doesn't reply?"
Friend : "What is difference between one-sided love and your persuit of physics study?"
            "Are you sure that you will be happy even though it gives back to you nothing?"

I cannot remember exact words we used But it may be like above sentences.
But I remember what I said to him.
Minhee : "It is possible because it is stadard of beauty for me."

I though about my word after read this essay. It makes me doubt about myself and my persuit. I don't know why I have to study except I want to. Some people ask me the reason why I have an imperative idea that I have to good at science, especially physics. I though equation is most clear explanation for all and equation possibly work for all cases. That is why science is logical.

But we frequently observe that most of people cannot understand what equation means and sometimes I do.
In this case, is it still posslble to say that eqatuion is most obvious way to describe nature? Even for me, physics cannot think indipendently from my emotion. I conduct some experiment because it SEEMS like important for me and I BELIEVE it will be needed in short time.

Beauty of clear explanation is kind of art for me.
And agreement comes from fully understanding makes me happy.
Harmonious description of equation (which covers general situation) with charactic of nature is the technic I regard.

I am not sure the unconscious reason I conduct physics experiment
as an artisan makes a piece of work
or as a scientist makes something worthy to human being.
logically I am the latter but I cannot refuse there is some reason based on the former case.
Because it is somewhat true for me.

The truth is this. Then is it possible to be scholar. I am already illogical.
(But Paul Dirac did either! Hm!)

[Situation 2]
Right after finishing discussion about physics problems with my study group members,
I told them

"Today is great for me !!!
 because I improve the way of explanation based  more on equation rather than just feeling.
This is the way of study what I have wanted to."

But one of member indirectly made me realize I have prejudice. He told me approach comes from feeling can be considered as intuition. Feeling is kind of intuition. However, at least until now, I need to know exact truth and numerical formulas since I am not confident with my physics knowledge. Yes it is! After I have confidence I will respect that more. I need more room for other ways of approachs. I agree with him :)

Also I have to accept the truth I am using illogical approach either.
