The main advantage of offline education lies in the shaping of learning atmosphere and interactivity. For most ordinary students who are not very interested in learning, have low self-discipline, and are easily distracted, offline Panama Phone Number List education is still the best solution (during the suspension of classes, Dingding was graded by many students in stages. The five-star thing once again proves the problem). The main advantages Panama Phone Number List of online education are convenience, resource sharing of famous teachers, and it is easier to automatically complete the push of personalized teaching resources by relying on big data analysis and AI technology. For students who are more motivated to learn, online education Panama Phone Number List provides a more luxurious boost at a relatively low cost. Therefore, purely from the perspective of learning effect, the best combination is: the main course is conducted offline; the assessment and auxiliary courses (preview, review, extension courses, etc.) are delivered online. At present, many students (especially K12 students and students receiving language training) have begun to use both online and offline Panama Phone Number List training products to solve this problem. However, due to the reported offline and online tutoring The classes do not belong to the same institution, so the content, progress, teaching Panama Phone Number List methods and standards are often incompatible; the student's learning burden has doubled, but the learning effect of 1+1>2 has not been achieved. How to use the same set of products to provide a complete closed loop of students' online and offline learning needs at the same time is the core of the educational product OMO. 0 From the perspective of customer acquisition Panama Phone Number List First, make a minimalist classification of common customer acquisition channels. Common online customer acquisition channels: SEM, SEO, online media promotion (traffic procurement), corporate self-media matrix, small programs/gadgets, etc. Common offline customer acquisition channels: offline media promotion, ground promotion, exhibitions, etc. Customer acquisition channels that can be done individually or online and offline together: BD, distribution, community marketing, etc. When the Internet was just emerging, the cost of online customer acquisition was much lower than offline customer acquisition, and the first batch of online educational institutions became pigs in the wind with an Panama Phone Number List extraordinary expansion speed. Afterwards, as waves of traffic dividends such as Weibo, WeChat, Mini Programs, and short videos were continuously divided up by homogeneous but wealthy education companies, the cost of acquiring customers through online channels was catching up. Finally Panama Phone Number List today, the online and offline promotion costs are basically the same, and no one has a clear advantage. The customer acquisition channels are all network-wide integration, and the competition can only be who can identify the "bullseye" and balance of their own channel group faster and more accurately, and constantly promote their "North Star Indicator".

It has communicated with Ali, and the other party has also adjusted, so The outer chain has been restored." Before this incident, on February 28, the “Feishu Documents” just released by ByteDance was stopped by WeChat from sharing links, indicating that access was stopped due to “induced sharing”. Afterwards, the official website of “Feishu” and “Feishu Conference” were blocked by domain names. After ByteDance appealed for a period of time, WeChat revised the ban prompt, and it became possible to copy the link into the browser for access. This is a relatively large-scale ban since WeChat changed its strategy last year. On October 18 last year, WeChat announced an upgrade to the "WeChat External Link Content Management Specification" to clarify the new types of violations. The upgraded "WeChat External Link Content Management Specification" has been officially implemented since October 28. On the evening of the 28th, WeChat officially announced the first batch of ban lists, which have quite a weight in the role. They are: Pinduoduo, JD.com, Tencent News, Meituan, Yunji, Mengtui, Weishi, Fanxiang Life, Tencent Games, Xiaomi Youpin, etc. In this list, there are not only big names, but also Tencent's stakeholders, as well as its own apps, to show severe Phone Number List punishment. It stands to reason that it is understandable to block the external links of competitors, but why not let go of their own related parties? In this regard, Jingdong CEO Xu Lei replied from the perspective of stakeholders: " Although WeChat is blocked from the perspective of user experience. External chain sharing, but it is good in the long run.” As for whether it is really good, it is hard to say, but at least Xu Lei said the reason why Tencent is so sensitive - Tencent wants to maintain the user experience of WeChat, which is an excuse and a means. It is generally judged that the backbone of social applications is young people, and the behavior of young people is more susceptible to environmental changes, and social applications are inherently insecure.

Laplace, a famous astronomer who was born in France in the 18th century, believed in the latter. He believed that objective laws and causal connections exist universally in nature and human society. Anything or event in the universe is and will always be the result of natural laws. In other words, everything has a cause and an effect. Mechanical determinism shrouded classical mechanics until quantum mechanics emerged, showing that elementary particles in the universe collapsed into a definite position of a probability wave at the moment of observation, and the determination of this "position" was considered to be a truly random event. But Einstein still believed that quantum mechanics, which exhibited pure randomness, was only a part of another, higher-dimensional, deterministic theory. As a rebuttal, the world remembers the phrase "God doesn't play dice." The story goes back to the dice. In fact, even if the dice is abstracted from the physical world and turned into an infinite polyhedron with a uniform mass and a shape close to a perfect sphere, it cannot be a counter-example for breaking through mechanical determinism. But even so, this does not prevent an object with such a simple structure from having such profound metaphysical meaning. It is itself an imperfect random number generator. Today, from modern cryptography, industrial design to artificial intelligence, the need for random numbers is everywhere. With the development of classical computers and the emergence of quantum computers, more random number generators continue to appear, and then the laws are exposed under more powerful computing power and become ineffective. The search for a closer to perfect random number generator has been moving forward in parallel with the breakthrough of cutting-edge technology. A research team from the Australian National Observatory recently published a new Phone Number List study on ELSEVIER. A completely new method of random number capture has emerged and passed the NSP800 standard. This random number generator is located 510 light-years from Earth and is a pulsar. Will the pulsar be that perfect dice? 1. Pulsars create random numbers A pulsar is a high-speed rotating neutron star, so named because it continuously emits electromagnetic pulses. Because of its extremely fast rotation speed (millisecond pulsar speed can reach 1000 revolutions per second) and extremely high celestial density (up to 1 billion tons per cubic centimeter), it has extremes that cannot be reproduced by laboratories on Earth. physical properties. One of the most well-known properties is that the rotation of pulsars has a very stable periodicity, which is the most accurate astronomical clock in nature. Although the process of consuming the rotation energy to make up for the outward radiation energy will cause the rotation to gradually slow down, this slowing down is very small, and the cycle stability can reach the minus 19th power of 10 - in other words, a pulsar The rotation period of the atomic clock will change by 1 second every 317 billion years, which is more than 10,000 times higher than that of the most stable hydrogen atomic clock.
