We like to make a show of how much our decisions are based on rational considerations, but the truth is that we are largely governed by our emotions, which continually influence our perceptions.
What this means is that the people around you, constantly under the pull of their emotions, change their ideas by the day or by the hour, depending on their mood.
You must never assume that what people say or do in a particular moment is a statement of their permanent desires.
Yesterday they were in love with your idea; today they seem cold.
This will confuse you and if you are not careful, you will waste valuable mental space trying to figure out their real feelings, their mood of the moment, and their fleeting motivations.
It is best to cultivate both distance and a degree of detachment from their shifting emotions so that you are not caught up in the process.

Internet activist Eli Pariser noticed how online search algorithms encourage our human tendency to grab hold of everything that confirms the beliefs we already hold, while quietly ignoring information that doesn’t match those beliefs.
We set up a so-called “filter-bubble” around ourselves, where we are constantly exposed only to that material that we agree with.
We are never challenged, never giving ourselves the opportunity to acknowledge the existence of diversity and difference.
Creating a difference that others don’t have is a way to succeed in your field, leading to the creation of innovations.
In the best case, we become naive and sheltered, and in the worst, we become radicalized with extreme views, unable to imagine life outside our particular bubble.
The results are disastrous: intellectual isolation and the real distortion that comes with believing that the little world we create for ourselves is the world.

The best way in which innovation changes our lives is by enabling people to work for each other.
The main theme of human history is that we become steadily more specialized in what we produce, and steadily more diversified in what we consume: we move away from unstable self-sufficiency to safer mutual interdependence.
By concentrating on serving other people’s needs for forty hours a week — which we call a job — you can spend the other seventy-two hours (not counting fifty-six hours in bed) relying on the services provided to you by other people.
Innovation has made it possible to work for a fraction of a second in order to be able to afford to turn on an electric lamp for an hour, providing the quantity of light that would have required a whole day’s work if you had to make it yourself by collecting and refining sesame oil or lamb fat to burn in a simple lamp, as much of humanity did in the not so distant past.

In one example of the important role of laughter in social contexts, Devereux and Ginsburg examined frequency of laughter in matched pairs of strangers or friends who watched a humorous  video together compared to those who watched it alone.

The time individuals spent laughing was nearly twice as frequent in pairs as when alone.

Frequency of laughing was only slightly shorter for friends than strangers.

According to Devereux and Ginsburg, laughing with strangers served to create a social bond that made each person in the pair feel comfortable.

This explanation is supported by the fact that in their stranger condition, when one person laughed, the other was likely to laugh as well.

Interestingly, the three social conditions (alone, paired with a stranger, or paired with a friend) did not differ in their ratings of funniness of the video or of feelings of happiness or anxiousness.

This finding implies that their frequency of laughter was not because we find things funnier when we are with others but instead we are using laughter to connect with others.

고등수학개념공식총정리.pdf

대한민국 수험생 중 10명 중 5명이 수학 포기자라는 사실 알고 있나요?

모평이나 학평, 수능 시험에서의 등급컷을 살펴보면 100명이 시험이 봤을 때 약 4.5 등급 약 50명 정도의 학생들이 수학 과목에서 원 점수 50점을 넘기기가 쉽지 않은 것으로 조사되고 있습니다. 결국 수험생 두 명 중 한 명은 50점 이하의 점수를 가지게 된다는 것입니다.

이렇게 국포자, 영포자도 아닌 수포자가 생기는 원인은 무엇일까요? 아마도 제 생각에는 중학교 3학년에서 고등학교로 진학하는 과정에서 오는 수학의 난이도로 1차 수포자가 생기고, 각 학년별로 그 진도에 맞추지 못해 생기는 2차 수포자, 그리고 해도 안되서 차라리 다른 쪽에 더 공부를 하자는 수능을 앞둔 고3 3차 수포자라고 생각합니다. ^^

사실 저 역시도 수학=대입합격이라는 절대 공식 속에 단순히 수학을 포기하지말자라고 하기엔 무리가 있는 듯 보입니다. 따라서 조금이나마 수학 공부에 도움이 되기위해 예비 수포자들을 위해 준비한 고등수학 124가지 기본 개념표를 제공해 드립니다. 사실 이 표는 (예비)고1 학생들을 위해 만든 자료인데, 아직 고등 수학에 대한 기본 개념이 안 잡혀 있다거나, 빠르게 공식 암기를 통해 정리하고 싶은 학생에게도 상당히 도움을 줄 수 있다고 봅니다.

앞서서 항상 말씀 드리는 내용이지만, 수학만큼은 단순히 난 포기할래라는 빠른 수포자가 되기 보다는 차근차근 인내심을 가지고 공부를 한다면 남보다 더욱 유리한 대입 합격의 길을 찾을 수 있을 것입니다!
