"Window period" you don't necessarily Know

 You can't tell where you've been all your life; Where you've been for half a day, you can say forever.

A few days ago, my friend Dachen invited us to jiuquan Satellite Launch Center to watch the satellite launch. The "base trip" was enough for us to reminisce for most of our lives. In the middle of winter in the desert, minus 20℃, thousands of people waiting in the open air playground, eagerly waiting for the launch window: at 23:44, the Long March 4C carrier rocket, quasi-second ignition, lift-off, lifting remote sensing 33 satellite and micro-nano technology test satellite successfully......

TV more than once watched the live broadcast of the satellite launch, but listen to 5-4-3-2-1, watching the fire, absolutely different shock. Another achievement is that, in the past, we often glimpsed the "window period" in media reports, but we chose to skip it. Only by observing the scene can we know the concept of the satellite launch window period: It is not the date of opening school, opening business or starting work, can be determined randomly, can be arranged artificially, can choose an auspicious date, but a group of science and technology workers meticulous, rigorous, scientific calculation.

I was suddenly in awe of the "window period". Friends in the space department say that the launch window period is a more appropriate time range for launching carrier rockets. The window period, wide in hours, narrow only tens of seconds, or even zero. The selection of the window period is mainly determined according to the special requirements of the energy equipment and measuring equipment on the spacecraft and the tasks performed after liftoff. Specific to Mars launch, mainly considering the distance between the Earth and Mars, July-August is a good window period. On this basis, the launch time is finally determined according to the meteorological conditions, the airspace control of the launch site and other factors.

"Window period" is a broad term. An online search shows applications in medicine, agriculture, forestry and fisheries, and social management. In fact, in addition to these "Windows" known to the public, people are constantly developing, cultivating and utilizing another kind of "window period" in their political, economic and cultural life.

The "window" for concerts or important football matches is usually on weekend evenings. Why is that? The vast majority of urban working class only have disposable time in the weekend, also have the mood to appreciate, watch.

Cinema line discount, "window period" generally set on Tuesday. Ordinary viewers can also think of reasons why attendance is lowest on Tuesday, and the only way to attract traffic is to offer discounts. Industry insiders analysis, Tuesday as a discount day, there are two big advantages: one is Thursday and Friday to release the film, the weekend is the peak, next Tuesday discount, can form another peak film; Second, if the discount increases the number of audiences, it may indicate that the first round of the film is priced high, which is conducive to grasp the market dynamics.

Some typical reports, achievement reports, not all in the eve of festivals, anniversaries, sometimes deliberately arranged in some places or departments to review the key moment of promotion. This is called a promotion window? An official mark time for many years, a heart for promotion, internal learning the organization department is to promote sex, immediately instructed the subordinate section organization concludes a series of typical reports (pictures, video), highlight the main leadership, work, and multi-channel, multi-platform distributing push up, create a harmonious, strong public opinion atmosphere. At the same time, repeatedly reminded the relevant departments to strictly control negative public opinion, outcrop on "pounce". -- The "window" for a promotion, the "overtime season" for a group of people.

For the purpose of scientific evaluation of communication effect, some critical reports now often avoid the weekly topic congestion peak, and set the "window period" for their manuscripts to be pushed at weekends, or even late at night or early in the morning. Why choose this "sleep time"? Holidays and nights are the "golden time" for public leisure and entertainment, which is conducive to the smooth reprinting and diffusion of manuscripts on portal websites and new media terminals in advance. The parties or departments criticized are often unable to respond in the middle of the night or at weekends. By the time the information is spread phenomenally, the parties or departments concerned have been criticized for a whole night or even a whole weekend. For successful communication, there must be some specific and precise "window period".

Everywhere you look, the world is a window: skylights, transom, rear Windows, portholes, shop Windows, French Windows... Those that can be studied, calculated and publicly released are the "bright Windows", while those that are unspeakable, hidden and unpredictable are the "dark Windows". "Dark window" is not always a wrong way, sometimes it is a survival strategy, emergency handling skills, and even the magic of surprise.

A "window period", you can peek into the real society. One more thing, is it also necessary to choose the right "window period" when examining the ecology of an organization and the state of a person?

Moroccan football team: "The most familiar stranger"

   When I was still in college ten years ago, I led a sightseeing group of more than 30 Moroccan students. Before meeting them, my general impression of the Moroccans was that they are from North Africa but closer to the Arab world. They have religious beliefs, are used to worship, and are inextricably linked with France.   When I saw the real person, I realized that the North Africans in front of me were actually a group of children playing with each other and having fun in time. They were about the same age as me at the time. I have all kinds of nicknames and nicknames. During the process of taking them to Badaling, the Summer Palace and Houhai, two classmates and I, together with more than 30 Moroccan students, realized "cultural integration" and "world unity" in the small group to some extent.   During the World Cup in Qatar, I was surprised to find that the little-known Morocco team, which was eliminated in the group stage of the last World Cup, after miraculou

Zeigarnik effect

  As a freelancer, you have to fight procrastination every day. "I've made up my mind many times, but I just can't change it. Is it because I'm slow or slow?". In fact, many procrastinations are irrational. Many obstructions are imagined by myself. So distract, postpone, avoid confrontation. It's cool to procrastinate, and it's cool to procrastinate all the time, so I can't do it. Concentration is also related to physical strength. When the physical strength is exhausted, it is even more difficult to concentrate. You’ll tell yourself: I’m too tired to do this—okay, another perfect procrastination.   In 1927, Bruma Zeigarnik's senior research found that people are more likely to care about unfinished and interrupted work than completed work. This is the Zeigarnik effect. For example, we often don't care much about what we have got, but we will especially cherish what we have worked hard but haven't got. Therefore, the TV series will tell you
