Chain Asia blockchain summit Zhengzhou station
On 19, 2018, "global media blockchain summit" was held in the financial hall of the Hong Kong stock exchange. The summit gathered more than 100 global media and dozens of top experts in the instry. At the meeting, we witnessed the establishment of the global media blockchain Alliance (bimg) and the release of bimg Hong Kong initiative, and discussed in depth the development prospect and instry trend of blockchain
member of the journalism and communication discipline evaluation group of the Academic Degrees Committee of the State Council Professor Yu Guoming, executive director of School of Journalism and communication of Beijing Normal University, delivered a keynote speech entitled "the value of mainstream media in the tide of technology" at the "2018 global media blockchain summit"
Yu Guoming said: "for the whole social communication in China and other major countries and regions in the world, including the process of blockchain construction, development In terms of the communication ecology in the process of evolution, the value of traditional mainstream media should also be indispensable. Although its share has really declined worryingly, such responsibility and value bearing are still very important. "
Yu Guoming further pointed out that traditional mainstream media's professional adherence, social status conferring function and local advantages are its great advantages. At the same time, with the development of social development and Internet technology, blockchain is not only a technology, but also a way to reorganize the society to a greater extent. Yu Guoming said: "in the words of Marx a hundred years ago, it is a technological form on top of such a new Internet technology as" Free Alliance of free people. ". To a large extent, it is a new form of social evolution after the Internet technology activates the indivial. Such a new form needs the mainstream media to play an important role in it, because in the process of such a new social evolution as blockchain, it is embodied in the so-called emergent evolution in system science, that is to say, the micro force and micro value released by Internet technology is a qualitative change in the development process and direction, which is a kind of social development A qualitative turning point in the development of the field, instry and market. "in the presence of all guests, the global media blockchain Alliance (bimg) was officially established at the meeting. Ding Laibin, Secretary General of the alliance, pointed out in his speech that the blockchain is really using the mechanism to let people see some changes that may occur in the future, and these changes may subvert the current state and make the social efficiency leap forward. In this process, the media function can not be absent, should play a supervisory role, exert a strong media supervision role, let investors distinguish right from wrong
Ding Laibin said: "the media is the public knowledge and conscience of the society and the supervisor of the development of the instry. To play this role well, we should be close to the game and stand where we can hear the gunfire. Therefore, if there is still a little distance between traditional media and blockchain before, let's eliminate this distance at today's summit. The listing of any enterprise is not the end, but the starting point. It is the same for many blockchain projects. From the beginning to the development, it also needs a lot of disclosure and planning, so that the enterprise can be presented to all the public and investors without reservation. It should be open and transparent, from the beginning to the end. Only in this way can the instry grow more healthily and more rapidly. "in the bimg Hong Kong initiative released at the event, Ding Laibin called on the media to join hands and make joint efforts to create a fair, just, honest, dynamic, harmonious and orderly instry public opinion environment; At the same time, the media should be encouraged to be open and inclusive, advanced in communication, and ecological innovation in information dissemination in the blockchain field, so as to continuously provide high-grade, high-quality information and services

If the time is t, the landing velocity is V, and the impact force is f. It can be calculated by the formula ft = MV
objects that fall only under the action of gravity without any resistance are called & quot; Free fall & quot;. An object, such as one that begins to fall from a static state under the action of the earth's gravity. The sky near the earth's surface can be regarded as a constant gravitational field. If the atmospheric resistance is not taken into account, the motion of the free falling body in this region is uniformly accelerated linear motion. Its acceleration is equal to the acceleration of gravity G
extended data:
the main characteristics of free falling body
the characteristics of free falling body motion are reflected in the word "free", which means that the object is stationary when it begins to fall, that is, the initial velocity v = 0. If the initial velocity of the object is not zero, even if it falls vertically, it cannot be regarded as a free falling body
(2) in the process of falling, the object is not affected by any other external forces (including air resistance) except gravity, and the resultant force of external forces is 0
(3) the falling time of any object is the same when it falls freely at the same heightsource of reference:
