1. Hello, the fastest running computer in the world is the blue gene / L of Lawrence Livermore National Laboratory, which is used for nuclear weapon research and development. It is composed of 131072 processors, and its computing speed reaches 280.6 teraflops per second, that is, 280.6 times 10 to the 12th power (280 trillion floating-point operations). The concept of this number is equivalent to that if each of the 6.6 billion people on earth takes a calculator and makes a simple calculation every five seconds, the calculation that people on the whole planet spend 60 hours doing is equivalent to that of blue gene / L in one second. The development of supercomputers in China is very rapid, represented by "Tianhe-1", "mole-8.5", "Rubik's Cube" and "ShenTeng 7000", which has reached the world's leading level. I hope you can click "adopt the answer" in the lower right corner, thank you!
2. Take the free computing power jointly launched by the tenth power and computing earth, which mainly provides free computing power support for projects that need a large amount of computing power output. The computing power bank can provide idle computing power for personal devices around the world and provide computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields.
3. The Japanese supercomputer "K" made by Fujitsu ranks first, becoming the fastest supercomputer in the world
the running speed of supercomputer K is 816 million floating-point calculations per second (petaflops), which is composed of 68544 sparc64 viiifx processors. Each processor has 8 built-in cores, and the total number of cores is 548352. According to Fujitsu, the supercomputer is still under construction and will be put into operation in November 2012, when the number of processors will increase to 80000<
previously, China's Tianhe-1A ranked first, and ranked second in the latest list, with an operation speed of 257 million floating-point calculations per second. At the same time, China is also improving the computing speed of Tianhe-1. In third place is the United States "Jaguar" (Jaguar), the speed of 1759 million floating-point calculations per second.

4. We need the mass m, angular velocity W, radius r of the earth and the distance between the latitude and the earth's center line r
G = GM / RR RWW
G = GM / RR RWW
5. It's not like this.
in the interior of the earth, the law of universal gravitation should also be obeyed, just like in the interior of a star, it is the universal gravitation that proces the fusion reaction.
because the height of the earth's surface is different, That is to say, the gravity you calculate on the eastern plain is actually equivalent to the gravity below the horizon of the Qinghai Tibet Plateau.
in fact, it is not clear under what circumstances the formula of gravity can be used. But generally, Newton's formula of gravity should be used in our calculation problems.
if your question is an option of multiple-choice questions, Then you can think it's right

7. In fact, people will not let such a thing happen, because once someone controls 51% of the computing power of the whole network, the security and non tamperability of the system will be invalid, then the decentralization system of bitcoin will collapse, and the price of bitcoin will plummet or even return to zero, which is bad news for the participants of the whole network. Therefore, we will spontaneously control the distribution of computing power in the whole network, so as not to let one company dominate. Even when many people find that the computing power of a certain mine is too large, they will take the initiative to withdraw from the mine. Now the most powerful mining pool in the whole network accounts for about 25% of the whole network.

Supercomputing Center's computing services are generally charged. You can go to the 10th power to learn about it. At present, the 10th power has launched free computing services
the tenth power cooperates with computing earth to launch the world's largest distributed computing resource computing power supply platform, providing free computing power support for projects requiring a large amount of computing power output. The computing power bank can provide idle computing power of personal devices worldwide, providing computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields
so far, the peak computing power is as high as 100p, which is equivalent to the computing power of tianhe-2, the world's fourth largest supercomputer, and can meet the needs of all computing power projects on the market

10. The problem is that gravity decays faster with distance. As like as two peas as like as two peas, we first use the economic principle of the oak razor, assuming that the other universe's other parameters are exactly the same, and the laws of physics adopted are exactly the same. So how fast does gravity decay? Let's assume that gravity decays twice as much as it does now, as in four-dimensional space, every time the distance doubles
