My daughter is now 7 years old, just like a little adult, and often remark to make adults laugh and cry. One of my students with a girlfriend to my house to deliver wedding, said the National Day They married.
Students girlfriend suddenly blushed.
I quickly snapped daughter, let her out to play. Pro go out, she pulled the girls hand about, proudly said: "Auntie, I want a little brother to play with. You help me birth to a brother?" Then it bounced out of play . The girl was embarrassed to head down, students are very good grace that they have something good-bye I left hastily, leaving dumbfounding me and I blame my daughter straight talking nonsense.
Jing Xiaxin think that little girls words are really funny, she wanted a little boy play with her, told people to give her students a little brother, like a boy or girl depends on her familys idea. Think again, a lot of boy or woman on the topic of how hot the Chinese secret court that the climate in Greece is said, and so saying, it seems that this knowledge, you want to have male to male students, would like a girl to Health women. And Recently, I read a Russian scientist on the fertility research articles, suggests that the sun affect human fertility gender perspective, which I extracted the essence of some of the readers.
Over the years, Russian scientists have been on the vagaries of the sun in the end what will study the impact of human-induced, and now obtained some unexpected results, that is: the sun also affects the human boy or girl. When solar activity is strong, magnetic field intensity on the large, high probability of Health and girls, contrary to Health and boys.
St. Petersburg and the Leningrad scientists state conducted a survey of 600 residents. In order to achieve perfect results, have to consider two main factors: the survey of the birthday and sex. Geomagnetic activity index is also very important, otherwise unable to carry out investigations.
Since 1914, about Earths magnetic field has been observed on the results of the electromagnetic, Ionosphere and Radio Wave Propagation Institute of St. Petersburg branch of the offer. Only those remaining with the data of geomagnetic observations Index – held in the hands of scientists, the situation of those who cozy up to the line together.
The researchers will honestly out of a particular persons birthday minus the 280 days ahead, this should be the days of fetal development, followed by books according to various people between 1914-1979 found fertile day of the geomagnetic field situation.
Results are very surprising. Survey results show that the magnetic field strength decrease in the case of boys than girls in the birth rate birth rate. This means that the magnetic perturbation in the days of pregnancy reduced, 9 months more than boys, boys with girls, the proportion of 16:10. The perturbation of the local magnetic field to the highest limit curve, the proportion of girls born with the boys is 15:10.
Although these studies with a medical nature, but absolutely can not do without the knowledge of geophysics. Scientists can only be viewed as a bystander of our planet.
As we all know, the Earths magnetic field is a very complex structure, which acts as the role of Earths protective shield. By the way, many researchers believe, precisely because of the geomagnetic field and its variants, have a life on the planet.
In fact, the formation of one sex chromosome X, Y not just accidental combination, but the body of a person in order to survive as organisms and smooth development of the complex process.
For example, the process generally biased in favor of pregnancy gave birth to female embryos. The reason why is there such unbalance, is that men and women in human evolution is given the mission is different: women wanted stability, men change, often want to be innovative.
This means that whenever the external conditions are not so good, like the rising level of magnetic field perturbation, the germ cells will provide the students a prerequisite for woman; the other hand, if the reduction in the level perturbation, that is in good condition , increase the probability of male students. The mechanism of these prerequisites is not clear there. But scientists have speculated that with the blood cells related to the number of free radicals in particles.
Perhaps that is because the change in blood components determine boy or woman, biologists have also discovered an interesting fact: When the winter is not an ordinary tough, and simply enjoy being miserable year, such as the temperature suddenly dropped, the snow instead of Rain, dramatic changes in atmospheric pressure, each organism will start its protection mechanism. Mankind is trying to maintain their fertility which the number of women. Now understand why the past 50 years women more than men? It was during this period, solar activity was significantly strengthened, the number of storms occurring over the earth also significantly increased.
