There is no end to practical development or theoretical innovation. The practice of the Party and the people is constantly advancing, and so must the theory that guides this practice. We have made strenuous efforts to explore a path of socialist construction suitable for China's conditions.

Under the guidance of Marxism, the Communist Party of China has united and led the people in ushering in the great leap of the Chinese nation from standing up, becoming rich and becoming strong.

The great practice of socialism with Chinese characteristics has proved to the world that Marxist "action" is a powerful theoretical weapon to guide China to prosperity and great national rejuvenation.

4.Draw vitality from open development

"Marx repeatedly warned people that Marxist theory is not a dogma, but a guide to action, and must be developed with changes in practice." The reason why Marxism can always stand in the forefront of The Times is because of its open theoretical characteristics.

Marxism is the product of history, with different forms and contents in different times. Engels said, "Marx's whole world view is not a doctrine, but a method. It provides not a ready-made dogma, but a starting point for further research and a method for such research."

Marxism inherently has the fundamental requirements of emancipating the mind, seeking truth from facts and advancing with The Times. It opposes conformism and conformism, and adheres to the unity of subjectivity and objectivity,

of theory and practice, and of inheritance and innovation. It provides us with a scientific position, viewpoint and method for understanding and transforming the world. The openness of Marxism is also reflected in its critical attitude towards all theories,

ideas and doctrines, including its own. Marxism has the courage to deny itself and constantly develops and grows in denial, which is not only the theoretical quality and practical characteristics of Marxism,

but also the correct attitude held by Marxism. In constantly exploring the new issues raised by the development of The Times and responding to the new challenges facing human society, Marxism is open to the present and the future, which fully demonstrates why Marxism "does".

Compared with Marx's era, great and profound changes have taken place in the development of human history. However, from the perspective of the development of human history, the world is still in the great era of moving from capitalism to socialism as pointed out by Marxism.

How to use Marxism to analyze and solve the problems of The Times, which inevitably requires Marxist theory itself to remain open, and constantly realize the transformation and innovative development of the theory itself.

This is the theoretical summary of Marxism and the expression of The Times by Chinese Communists in a scientific attitude in the new era, especially the original contribution made to the innovation and development of Marxism in answering the major issues raised by The Times and practice.

It has made scientific socialism full of strong vitality in China in the 21st century, and profoundly demonstrated the open character of Marxist theory. In the positive interaction between theoretical innovation and practical innovation, it vividly interprets the true meaning of why Marxism "does".September "Science" myth list: Who says that eating bamboo charcoal food can detoxify and nourish the face?

The latest edition of the "Science" myth list is here! After X-ray found pregnant, the child really can't want? Eating "bamboo charcoal food" can absorb toxins in the body and achieve detoxification and beauty? None of this is true.

The "Monthly 'Science' Rumor List" is jointly released by Beijing Science and Technology Association, Beijing Cyberspace Administration Office and Capital Internet Association under the guidance of Beijing Science and Technology Journalists and Editors Association and Beijing area website joint rumor refuting platform. Let's take a look at the "pseudoscience" debunked by September's myth list.

X-rays have a great impact on human health, especially for pregnant women, babies and fetuses. So after taking the X-ray found pregnant, the child can not want, to timely abortion.

Scientific research has confirmed that there is a threshold for the adverse effects of X-rays on all mammals and young animals, including humans, and even embryos. For both adults and fetuses, radiation exposure must reach a certain level to cause damage. Therefore, damage cannot be talked about in isolation from the radiation "dose".

For the fetus, different gestational age corresponds to different safe doses of radiation. In 2017, the American College of Obstetricians and Gynecologists issued guidelines: 0 to 2 weeks of gestation,

teratogenic dose threshold is 50 to 100mSv (millisieverts), the main impact is fetal death; From 2 to 8 weeks of gestation, the teratogenic dose threshold is 200mSv, and the main effect is congenital malformation.

At 8 to 15 weeks gestation, the teratogenic dose threshold is 60 to 310mSv, and the main effects are intellectual development and malformation. Therefore, the minimum influence dose threshold for the fetus is 50mSv, which is theoretically safe as long as it is not exceeded.
