Mining machinery flood
25000 mining troops in Sichuan: a flood cost hundreds of millions, most afraid of power failure and loneliness
these computing power are scattered along the Da River, a tributary of the Minjiang River. They inlge in the night of Dalate Banner in Ordos, and sleep soundly in a small city in Yili Kazakh Autonomous Prefecture of Xinjiang
today, bitcoin's total network computing power has reached about 30 billion hash collisions per second, equivalent to about 600 tianhe-2 supercomputers, and it is still growing at a high speed. " Wu Jihan, the founder of bitcontinent, wrote in the beauty of computing power
he preached a set of infinitely beautiful "computational aesthetics", but behind the aesthetics is the cruel computational world and interests. Mining is moving towards instrialization step by step and becoming a game of capital
at this time, decentralized mining machines and pools began to appear. They called themselves revolutionaries and wanted to change the extremely monopolized bitcoin world
"cloud computing power mining" is one of them
their way of playing is to establish a number of distributed mines and provide computing power leasing services with tens of thousands of real mining machines
"the current computing power is too concentrated, and some decentralized play methods are difficult to change the current pattern and ecology." Li Ke said
but the essence of blockchain is decentralization. The miners still have the belief that eventually the mining instry will be broken by the decentralized mining pool
this may be the only belief that keeps them going
how long will it take
"5-10 years, slowly nibbling at the giant's territory." Li Ke said
but will giants wait for the revolution? Will they fight back
the battle of computing power and the spark of revolution have just been ignited

3M China was registered in China in November 1984. It is an early wholly foreign-owned enterprise established outside Shenzhen Special Economic Zone. So far, 3M has invested more than US $1 billion in China, established 9 proction bases, 27 offices, 4 technology centers and 2 R & D centers, and has more than 8200 employees
as one of the first wholly foreign-owned enterprises to enter China, 3M China has always closely grasped the pulse of China's economic development in the past 30 years, adhering to the localization development strategy of "taking root in China and serving China", and actively supported China's economic construction and development with diversified technologies and solutions. From infrastructure construction to the rise of manufacturing instry, from made in China to created in China, from export driven to promoting domestic demand, 3M closely connects the development strategy of enterprises with the development pace of China, and helps the rapid development of Chinese market. This also makes 3M one of the most successful localization enterprises in China.
for example, according to bishop Usher's genesis, the creation of the world is set at 9:00 a.m. on October 23, 4004 B.C. On the other hand, the natural environment, such as mountains and rivers, changes little in human life cycle. So people usually think of them as unchanging backgrounds. Either as an empty landscape has existed for an infinite time, or it is created at the same time as human beings< But not everyone likes the idea that the universe has a beginning. For example, Aristotle, the most famous Greek philosopher, believes that the universe has existed for an infinite time. Something eternal is more perfect than something created. He pointed out that the reason why we see development in this situation is that floods or other natural disasters have repeatedly brought civilization back to its infancy. The motive of believing in the eternal universe is to avoid resorting to the interference of God's will in order to create the universe and start its operation. On the contrary, those who believe that the universe has a beginning regard the beginning as an argument for the existence of God and God as the first cause or motive force of the universe
if people believe that the universe has a beginning, the obvious question is, what happened before the beginning? What was God doing before he created the universe? Is he preparing hell for those who ask such questions? Immanuel Kant, a German philosopher, is very concerned about whether the universe has a beginning. He felt that whether the universe had a beginning or not, it would cause logical contradiction or antinomy. If the universe has a beginning, why wait for an infinite time before it begins. He called this the main point. On the other hand, if the universe has existed for an infinite time, why does it take an infinite time to reach the present stage. He called this the antithesis. Whether the topic or the antithesis is based on Kant's hypothesis, and almost all people do the same, that is, time is absolute, that is, time passes from the infinite past to the infinite future. Time is independent of the universe. In this background, the universe can exist or not. To this day, in the minds of many scientists, such a picture remains. In 1915, however, Einstein proposed his revolutionary theory of general relativity. In this theory, space and time are no longer absolute and the fixed background of events. Instead, they are dynamic forces, the shape of which is determined by matter and energy in the universe. They can only be defined in the universe. It's meaningless to talk about the time before the beginning of the universe. It's a bit like looking for something south than Antarctica. It is undefined
if the universe is essentially unchanged with time, as was generally believed before the 1920s, there is no reason to prevent the definition of time at any earlier time in the past. In this sense, any so-called beginning of the universe is man-made. So it could be that the universe was created last year, but all the memory and physical evidence suggests that it is much older. This leads to profound philosophical problems about the meaning of existence. I will adopt the so-called positivist approach to deal with these problems. In this method, the idea is that we interpret our sensory inputs according to our model of constructing the world. People can't ask whether this model represents reality, they can only ask whether it works. First, a simple and elegant model can explain a large number of observations; Secondly, if the model makes a clear prediction that may be observed, tested or falsified, it is a good model
according to the positivist method, people can compare two models of the universe. The first model is that the universe was created last year, while the other is that the universe has existed for a long time. A pair of twins were born earlier than a year ago, and the model of the universe that has existed for more than a year can explain things like twins
on the other hand, the model of the creation of the universe last year cannot explain such events, so the second model is better. One cannot question whether the universe really existed a year ago, or whether it just seemed that way. In the positivist approach, there is no difference between them
in an unchanging universe, there is no natural starting point. However, in the 1920s, when Edwin Hubble started using a 100 inch telescope on Mount Wilson, things changed fundamentally. Hubble found that stars are not evenly distributed in the whole space, but a large number of clusters called galaxies
Hubble measures the light from galaxies, and then determines their velocities. He predicted that as many galaxies would fly to us as they would fly to us. This should be in a universe that does not change with time. But to Hubble's surprise, he found that almost all the galaxies flew away from us. In addition, the farther away the galaxy is from us, the faster it flies away. The universe doesn't change with time, not as everyone thought. It's expanding. The distance between galaxies increases with time. The expansion of the universe is one of the most important intellectual discoveries of the 20th century or any century. It changes the debate about whether the universe has a beginning. If galaxies are moving apart now, they must have been closer in the past. If their speed had been constant in the past, then about 15 billion years ago, all galaxies would have landed on one another. Is this the beginning of the universe
many scientists still don't like the beginning of the universe. Because it seems to mean that physics is collapsing. People have to turn to the role of the outside world. For convenience, we can call it God to determine how the universe started. So they put forward some theories. In these theories, the universe is expanding at the moment, but there is no beginning. One of them is the steady state theory proposed by Bondi, Gould and Hoyle in 1948. In the theory of steady state, the idea is that as galaxies leave, new galaxies will be formed from the hypothetical matter created continuously in the whole space. The universe will exist forever, and it will appear the same all the time. This final nature, from a positivist point of view, has great advantages as a clear prediction that can be tested by observation. The Cambridge Radio Observatory astronomy group, led by Martin Lyle, investigated weak radio sources in the early 1960s. These sources are fairly evenly distributed in the sky, indicating that most of them are located outside the Milky way. On average, weaker sources are farther away
the steady state theory predicts that the number of sources corresponds to the shape of the graph of source intensity. However, observations show that there are more weak sources than predicted, which indicates that the density of sources was higher in the past. This is in conflict with the basic assumption that everything in the theory of steady state is invariable in time. Because of this, and for other reasons, the steady state theory has been abandoned
another attempt to avoid the beginning of the universe is to suggest the existence of an earlier contraction phase, but e to rotation and local randomness, matter will not fall to the same point. On the contrary, different parts of matter will stagger, the universe will expand again, and the density will remain limited. Two Russians, livschitz and kharanikov, actually claim that they have proved that a general contraction without strict symmetry always causes a rebound, while the density remains limited. This result is very convenient for the materialist dialectics of Marxism Leninism, because it avoids the intractable problems about the creation of the universe. Therefore, it became an article of faith for Soviet scientists
I was a 21-year-old graate student when livschitz and haranikov published their assertions, and I was looking for a problem in order to complete my doctoral thesis. I didn't believe what they called proof, so I started to work with Roger Penrose to develop new mathematical methods to study this problem. We proved that the universe can't rebound. If Einstein's general theory of relativity is correct, there is a singularity, which is a point with infinite density and infinite curvature of space-time, where time has a beginning
a few months after I got the first singularity result, in October 1965, people got observational evidence to confirm that the universe had a very dense beginning, which was the discovery of a weak microwave background throughout space. These microwaves are the same as those of the microwave oven you use, but they are much weaker. They can only heat the pizza to minus 270.4 degrees Celsius, and they can't even thaw it, let alone bake it. You can actually observe these microwaves yourself. Tune your TV to an empty channel, and what percentage of the snowflakes you see on the screen are e to the microwave background. The radiation left by the early very hot and dense state is the only reasonable explanation for this background. As the universe expands, the radiation cools down until we see its faint remnant today
although Penrose's and my own singularity theorems predict that the universe has a beginning, they do not tell the universe how to start. The general relativity equation collapsed at the singularity. In this way, Einstein's theory can't predict how the universe starts, it can only predict how it will evolve once it starts. There are two attitudes to Penrose and my results. One is God's choice of the way to start the universe for reasons we can't understand. This is the view of John Paul. At a cosmological conference at the Vatican, the Pope told delegates that it was possible to study the universe after it had begun. But they should not explore the beginning itself, because this is the moment of creation, this is the body of God. I congratulated myself that he didn't realize that I had published a paper at the meeting, which just mentioned how the universe started. I don't want to be presented to the inquisition like Galileo
another explanation for our results, which is also agreed by most scientists. This result shows that in the very strong gravitational field of the early universe, general relativity collapsed and must be replaced by a more complete theory. Because general relativity doesn't pay attention to the small-scale structure of matter, the latter is
