The scientific basis of human blood buns

In Lu Xun's article, eating human blood steamed buns referred to a plot in " The Madman's Diary." In this novel, the protagonist "Madman" was persecuted by the feudal forces and trapped in a secret room. In order to survive, he began to eat human blood buns to maintain his life. This kind of behavior was described as extremely cruel and disgusting. It was one of the cruel means of the feudal forces. This plot reflected Lu Xun's criticism of the feudal forces and the exposure of the darkness of society. It also provided an important theoretical basis for the later anti-feudal movement.

No. There was no scientific basis at all. It was just a misinterpretation of the Mayan calendar.

No. In biological terms, the female and male sexual organs develop from different embryonic precursors and have distinct structures and functions. There is no natural process where a clitoris turns into a penis.

No. In scientific terms, the concept of 'egg pregnancy' as it's presented in such a story is not based on any known scientific facts. Pregnancy in living organisms follows specific biological mechanisms, and this doesn't include an egg being 'pregnant' in an unusual way.

The gravitational slingshot was a sci-fi concept that used the gravity of an object to launch a projectile. In the Mars Rescue novels, gravity slingshots were used to launch projectiles to save humans trapped on Mars. However, the gravitational slingshot was not a real scientific concept and had not been proven by science or experiments. Therefore, the gravity slingshot plot in the Mars rescue novel did not conform to modern scientific knowledge.

No, currently there is no scientific basis for pre life stories. The idea of pre life memories is more in the realm of the spiritual and philosophical. Scientists deal with facts that can be measured, observed, and replicated. Memories of pre life, which are often anecdotal and vary greatly from person to person, don't fit into the scientific method. However, that doesn't stop people from believing in them on a personal or spiritual level.

Absolutely not. A girl's life is sustained by things like eating a balanced diet, getting enough sleep, and having a normal physiological function. Sperm has no connection to these aspects of a girl's life. Scientifically, the female body has its own set of mechanisms to maintain life, and sperm is not one of them. Reproduction is a separate process that occurs when a female and male decide to have a child together, but it is not related to a girl's day - to - day survival.

Wormholes are mostly science fiction. There's no solid proof they exist in reality.

" Tempered into steel " was a literary term based on the chemical composition of iron. The chemical composition of iron is iron, which contains impurities such as silicon, carbon, sulfur, etc. When heated, iron will react with oxygen to produce iron dioxide. When heated further, the iron dioxide will be decomposed into iron and oxygen to obtain purer iron. This process was known as " smelting iron." Therefore," Tempered into Steel " meant that the impurity content of iron was reduced to less than one percent through repeated smelting to obtain purer iron. This pure iron usually had high strength and was used to make various weapons, tools, and buildings.

There was no conclusive scientific explanation for the humanoid shadow. Although there were some theories that tried to explain the appearance of these shadows, there was not enough evidence to support these theories. One explanation was that these shadows might be an optical phenomenon, a darker area formed by objects blocking the transmission of light. However, this explanation could not completely explain the specific shadow humanoid phenomenon that people saw under the light. Therefore, the scientific explanation for the humanoid shadow remained an unsolved mystery.
