Who gave his life for scientific exploration? Give specific examples.

From 65438 to 0896, Nobel himself suffered from angina pectoris and heart disease, which were very serious. Ironically, the doctor advised him to take nitroglycerin (which was proved to be effective by experiments at that time, but there was no theoretical support), but he ignored it until his death.

Until 100 years later, three scientists who won the 1998 Nobel Prize in Medicine found that nitric oxide in nitroglycerin is a signal molecule produced by the body, which can relax blood vessels and promote blood circulation.

Theoretically, it is good for the cardiovascular system. 1896 65438+February 10 Nobel died in San Remo, Italy, at the age of 63.

2. Peng

18 May 1980 to17 June 1988, Peng was the leader of a scientific expedition in Lop Nur, China. He crossed Lop Nur Lake Basin for the first time and collected many biological and soil samples and mineral fossils in the lake basin.

A large number of first-hand scientific research materials have been collected, which has made forward-looking preparations for the comprehensive development of Lop Nur in China. But unfortunately, this great scientist has disappeared. The country has sent more than a dozen planes, dozens of cars and thousands of people to search four times.

Facing the sandbags, sand beams and sand dunes blown by the black storm, there is no trace. People finally know that this great scientist has turned into a "robbery" and has been buried in Lop Nur.

3. Columbus

Columbus remained optimistic even in this difficult adversity. In order to find a passage to another ocean, he explored a bay and a river, but without success.

Perhaps because he learned from the Indians near Panama that there was no waterway or strait connecting the two oceans, Columbus gave up his search for the passage and began to look for gold again.

However, the situation of the fleet is getting worse and worse. At first, in mid-April, a light sailboat ran aground on the sandbar. Then, another ship was eaten by maggots. In this tropical heat, the other two ships are also in danger of being eaten by worms.

In this case of necessity, Columbus ordered the ship to dock on a sheltered beach, and the crew barely lived, because it was completely impossible to return to Hispaniola by such a ship.

Later, Columbus sent two men back to Santo Domingo by canoe for help, but they never came back. Columbus was bedridden with arthritis, and about half of him couldn't bear to wait for his crew to get up and make trouble.

1504 65438+1At the beginning of October, they left without Columbus' permission and wanted to return to Hispaniola. However, how could their canoes stand the rough sea? Soon they were all blown back to Jamaica by strong winds.

1 On June 29th, 504, the ship that had been waiting for1years finally arrived here, and Columbus and his crew returned to the island of Hispaniola. Columbus, his son, brother and 22 other members returned to Spain on a chartered ship.

The date of arrival in Spain is1504165438+1October. 1506 On May 20th, Columbus died. Until his death, he always thought that he had been to Asia.

4. Madame Curie

/kloc-in June, 1934, I was admitted to the Sanceromo sanatorium in Haute Savoie province. On July 4th, he died of pernicious anemia (caused by radium) in a nursing home. Dr Toby wrote this report: "His illness is a secondary anemia, which develops rapidly and is accompanied by fever.

There is no hematopoietic reaction in bone marrow, which may be due to damage caused by long-term cumulative radiation. Hearing the bad news, George Fanil, one of her favorite students, wrote, "We lost everything." Cai Yuanpei was also very sad after listening.

1on July 8, 934, he sent a message of condolence in French: "Mr. President of Paris University: I was shocked to learn that Madame Curie passed away. On behalf of Academia Sinica, I would like to express my condolences! I deeply feel that her death is a great loss to the French scientific community. Please give my regards to her family. Cai Yuanpei. "

On July 6th, he was buried in Curie's tomb in Paris. Her brother (Joseph Scollo Dovski) and sister (Bronis Lava de Luska) spilled dirt from Poland on the grave.

5. Hideki Noguchi

Hideki Noguchi is the first scientist to isolate syphilis pathogens from the central nervous system of patients who are thought to be paralyzed by syphilis. Perfecting the technology and theory of Wasserman reaction; Wasserman's skin test for syphilis has improved.

The pathogen of Oroya fever was also cultivated. In addition, a method of cultivating microorganisms that have never grown in test tubes in the past was designed, and Treponema pallidum was successfully cultivated. Vaccines and antiserum against polio, trachoma and yellow fever were also studied.

Hideki Noguchi, regardless of his age, went to Africa to inspect "yellow fever" in person. Unfortunately, he contracted the disease and died on May 2 1928. In June 65438+May of the same year, his body was transported back to a cemetery in the northern suburb of new york for burial.

Mr. Noguchi's inscription is: "He devoted his life to science. He was born for mankind and died for mankind. " Mr. Noguchi is highly respected in Japan, and many Japanese, especially teenagers.
