British Prime Minister Boris Johnson was transferred to intensive care because of the deterioration of the virus. Johnson’s “receiver” has also become the focus of British public opinion. When asked by the media whether Dominique Labu, the British foreign minister who deals with affairs on behalf of Johnson, has obtained the “nuclear codes”, British Cabinet Secretary Michael gove refused to disclose who should be responsible for the “nuclear codes” of the UK, the Guardian reported Monday.

Code scanning of public places in Wuhan


At present, the epidemic prevention and control work is in the most arduous critical stage. In order to further cut off the transmission chain and reduce the infection rate, in accordance with the provisions of the law of the people’s Republic of China on the prevention and control of infectious diseases, we hereby announce the following matters related to further strengthening the prevention and control of epidemic situation in public places:
1、 Strict management of public places closure. Public places (including movie theater, entertainment hall, Internet bar, chess and card room, music hall, swimming pool, gym, beauty salon, training institution, exhibition hall, museum, art gallery, library, gymnasium, park, etc.) in the city are temporarily closed; all religious places are temporarily closed to the public.
2、 Strictly manage the opening of public places. The public places that must be open shall be managed by code scanning in and out. Hotels, hotels, supermarkets (shopping malls), agricultural (fair) markets and other crowded places should establish a daily health monitoring system. The entry personnel must take temperature and wear masks, keep a certain distance, and do a good job of self-protection. Those who do not wear masks are not allowed to enter. In case of abnormal body temperature, the patient shall be sent to fever clinic as required, and the prevention and control work such as registration, information reporting and environmental disinfection shall be done well.
3、 The registration system for purchasing drugs in retail drugstores shall be implemented. When purchasing cough, fever and other drugs, the personnel shall fill in the ID card number, personal contact information, contact information of emergency contact person, detailed address and other information, and the pharmacy shall register and report to the superior.
4、 Strict sanitation management in public places. Strengthen indoor ventilation and air exchange in public places, adopt natural ventilation to ensure air circulation. If the central air conditioning system is adopted, the return air channel shall be closed to ensure the operation of fresh air, and the cleaning and disinfection shall be done regularly as required. The business units of public places shall regularly clean and disinfect indoor areas and public facilities, especially elevators, door handles, faucets and other articles. Public goods and appliances shall ensure health and safety, and the articles and appliances that can be used repeatedly shall be disinfected one by one. It is forbidden to reuse the disposable articles and appliances.
5、 Strictly handle the epidemic situation in public places. The main person in charge of the public place business unit is the first person in charge of the epidemic prevention work in the public place. Measures such as appointment service and quota management should be taken to reduce the crowd gathering in the business place. Customers without masks are not allowed to enter. All citizens should consciously abide by the regulations on epidemic prevention and control. Novel coronavirus should be strengthened by the competent departments of the city and district authorities. The offenses against the administration of public security should be punished. If the offenses are violated, the Supreme People’s court, the Supreme People’s Procuratorate, the Ministry of public security and the Ministry of justice shall transfer the judicial organs’ treatment to the provisions of the law on punishing the crime of obstructing the infection of new coronavirus and preventing and controlling the epidemic of pneumonia (FA 2020 [7]). And make it public.
This Circular shall go into effect as of the date of promulgation, and the time of cancellation shall be announced separately.

8 days of non Hubei new consecutive drop


According to statistics from the national health and Health Commission, 377 new confirmed cases were found in areas other than Hubei Province from 0-24 on February 11, with a downward trend for the eighth consecutive day. In the past, there were 890 cases (3 days), 731 cases (4 days), 707 cases (5 days), 696 cases (6 days), 558 cases (7 days), 509 cases (8 days), 444 cases (9 days) and 381 cases (10 days).

NASA sweeper challenge


I believe that many people’s circle of friends have been swiped by such a message recently.
“February 7 (maybe 8, 9, 10, 11, or some other time) is a special day. NASA once said that the earth has the least gravity, so the broom can stand up.”
Sounds like science fiction, doesn’t it? After a lot of people tried, exclaimed: really can!
But what is the real situation?
We searched the Internet for information related to “NASA broom”, but this is only the information on the forum, there is no official NASA information. Well, if NASA really said that, there would be English materials.
But the results of the search are more about the broom nebula and the use of laser brooms to remove space debris.
It’s related to an old joke in the United States, which believes that spring starts with the least gravity, allowing the broom to stand upright. Other research results on reddit show that the strange behavior of brooms is related to the solar eclipse in 2017, that is to say, there are different days and different explanations for the upright brooms.
So, what is the reason for the broom to stand upright?
First, it’s not because of the alignment of the planets or the rotation of the earth. The United States’ Wired magazine once calculated that Venus, the nearest planet to the earth, and Jupiter, the largest mass in the solar system, exert far less gravity (10-8n) than the earth’s gravity (about 10N) on the broom, which is impossible to make the broom stand upright.
So what makes a broom stand upright?
In fact, the problem is very simple, because the center of gravity of the broom is closer to the broom hair than the high point of the broom handle. You can test the center of gravity of the broom by placing it horizontally on your fingers, like a seesaw.
So when you split the broom hair, the center of gravity is naturally close to the bottom, and it’s not hard to find a stable point. If the broom is new and the hair is straight and hard, it’s easier to support the center of gravity.
Because everything falls, the reason is that the center of gravity has no support. As long as the center of gravity has support, all problems will be solved.
So, the so-called broom challenge is just a test of your ability and patience to find the center of gravity. It has nothing to do with NASA.
