How does Pai participate in mining
1. It is essentially like an e-commerce platform
2. He said that making money is to earn money, which is worth one yuan of consumption power
3. After asking, can't I cash the money
however, because of its consumption value, if it can circulate, it can still play well
you can also become a business like Taobao. The function of paipai coin is to download the novels you want to download. It's a local download and doesn't need any download tools
you can also have a pet or add a skill, and the rest is useless
paipai coin can also be used for writing or exchanging prestige. Some sectors, such as tanmei, need prestige 20 to enter
hope to help you.
First of all, you need to download a mining app from the official website of pinetwork on Android:
note: after clicking lightning, you need to click again after 24 hours. If you don't click lightning, you will stop mining. OK, the mining process has been completed< br />
you have to do it yourself in the fortress<
the retinue can be put into the level 2 building, which needs corresponding professional skills, for example, the mine needs retinue with mining skills
retinue can be put into the fortress to increase the proction of Fortress building orders,
when you go to the fortress building to receive goods every day, put the retinue into the building,
after receiving goods, pull the retinue out and continue to upgrade the retinue task.
In different historical periods, it was constrained by the development level of proctive forces and science and technology, π The calculation method, efficiency and accuracy are different. PI π The exploration of the calculation method mainly includes experiment period, geometry period, analysis period and computer era
1, experimental period -- estimation of PI:
a Cuban Babylonian stone plaque (about 1900-1600 BC) clearly recorded that pi = 25 / 8 = 3.125. Ancient Egyptian relics of the same period, Rhind mathematical papyrus, also show that Pi is equal to the square of fraction 16 / 9, about 3.1605. Egyptians seem to have known PI earlier
The Great Pyramid: why was it built, and who built it The pyramid of Khufu, built around 2500 BC, is related to PI. For example, the ratio of the perimeter to the height of a pyramid is equal to twice the PI, which is exactly equal to the ratio of the perimeter to the radius of a circle. Satapatha brahmana, an ancient Indian religious masterpiece written in 800-600 BC, shows that Pi is equal to the fraction 339 / 108, about 3.1391. We can use the special symbols of all kinds of input methods to enter the special symbols of input methods
1 π The transcendence of PI denies the possibility of turning circle into square, which is an ancient problem of ruler drawing, because all ruler drawing can only get algebraic number, and transcendental number is not algebraic number
π It is an irrational number, that is, it can not express the ratio of two integers. It was proved by Swiss scientist John Heinrich Lambert in 1761. In 1882, Ferdinand von Lindemann proved it π It's transcendental, that is π It can't be the root of any polynomial with integer coefficients
International PI2 π Japan:
in 2011, the International Mathematics Association officially announced that March 14 of each year will be the International Mathematics Festival, and the source is the Pi of ancient Chinese mathematician Zu Chong
International Pi Day can be traced back to March 14, 1988. Larry Shaw, a physicist at the San Francisco Science Museum, organized the staff and participants of the museum to make 3 and 1 / 7 circles around the museum Monument (22 / 7, π One of the approximations) of circular motion, and eat fruit pie together. After that, the San Francisco Science Museum inherited this tradition and held celebrations on this day every year
