Analyze jokes from a scientific point of view

Our world is being changed step by step by the power of science, but the process of being changed is not always smooth. At many critical moments in history, scientific discoveries and inventions were criticized and opposed at that time. Therefore, a scientific discovery and invention may take years of experiments, experiments, improvements and proofs before it can finally be accepted correctly by everyone, even before it was considered absurd and stupid.

1. continental drift theory

191265438+1October 6th, Alfred Wegener, a 32-year-old German geophysicist and meteorologist, dared to put forward an unusual idea based on his previous observations: all the land on the earth was once a single supercontinent, just like a jigsaw puzzle. Many plant and animal fossils spanning many continents have been found in Wei Gena, and mountains and rock formations matched with each other between plates have also been found.

But because of this scientific thought, he was accused of "mobile crustal disease, wandering polar plague" and his scientific discovery was regarded as "paranoia". Because geologists at that time insisted that continents were connected by land bridges and mountains were caused by the contraction of the earth, Wei Gena's scientific thought was completely despised. It was not until the 1960s that a new generation of scientists discovered the evidence of seafloor spreading and tectonic plate movement. However, Wei Gena did not live to that day.

2. Theory of species evolution

When biologist Charles Darwin published his book The Origin of Species in 1859, the world scientific community was in an uproar. Darwin's proposition that "life on earth has a common ancestor" is considered absurd. Although his science is very solid, for a time, his theory of evolution was ridiculed and criticized by powerful religious institutions. Until the 1970s of 19, evolution was considered as the mainstream of science.

3. Sun-centered theory

Although "Heliocentrism" and the earth's orbit around the sun were put forward to varying degrees in ancient history, many theoretical knowledge was lost in the Middle Ages. When astronomer Nicholas Copernicus put forward the concept of "Heliocentrism" in the first half of16th century, But before long, he was criticized by religious leaders such as Martin Luther and the Catholic Church.

Most educated people in the world believed in "geocentric theory" until Italian astronomer galileo galilei accepted "Heliocentrism" in17th century. It put forward the so-called Copernicus theory by using observational evidence. However, his evidence attracted the attention of the Inquisition to his heretical views, because in the Bible, our world will not move. 16 16 February, Copernicus was banned. 1633, Galileo was convicted of heresy and placed under house arrest.

4. Modern preservatives

Our world is full of many invisible microorganisms. Joseph lister, a surgeon, spent many years applying Louis Pasteur's microbiology work to hospital environment to develop a preservative to reduce postoperative mortality.

However, his idea was condemned by the organization, and the famous medical magazine The Lancet even warned Liszt's practice. Later, after he was able to prove the effectiveness of anti-corrosion technology through conclusive evidence and teach it to a new generation of students unaffected by old ideas, his research was widely recognized by the medical community all over the world.

5. Space flight

If you are interested in space exploration, you may know the name Goddard in the United States more or less. It appears in the name of NASA Goddard Space Flight Center Research Laboratory and Goddard Space Research Institute. Today, he is regarded as a revolutionary in space flight, and he started the world space race.

In the 1920s, Goddard was derided as an ass. Why? Because he thinks he can send a bow into space. 1920, an editorial of The New York Times even condemned his innocence and ignorance. At the same time, he was also opposed by the dean of the college and the Smithsonian institution.

But Goddard was not intimidated. Despite repeated failures, he persisted. On March 1926, he made his first successful flight with a liquid propellant rocket. Although this historic flying height is only 13 meters, its duration is 2 seconds. But it proves that flying into space can be done. The first space shuttles landed on the moon. Three days ago, The New York Times secretly withdrew his editorial about him.
