2. Madame Curie: studying radioactive elements, suffering from cancer (leukemia).
3. Deng Jiaxian: Two bomb dads, who suffered from rectal cancer due to radiation, died at the age of 62.
4. hippasus: The irrational number root number 2 was discovered, which could not be expressed as the quotient of two positive numbers, thus leading to the first mathematical crisis in the history of western mathematics. ? The discovery of irrational numbers expands the concept of numbers. Hippasus himself was punished for violating the principle of proportionality and was thrown into the sea and drowned.
5. Galileo: Agree with Copernicus' claim, be interrogated without restriction, not be under house arrest, and lose your freedom.

Madame Curie's knowledge expansion;
Marie Curie (1867165438+1October 7th-1July 4th, 934), born in Warsaw, is called "Madame Curie" and her full name is Marie Sklodowska Curie (Maria Sk? Odowska Curie), a famous Polish scientist, physicist and chemist in France.
1903, Mr. and Mrs. Curie and becquerel won the Nobel Prize in physics for their research on radioactivity.1910/year, they won the Nobel Prize in chemistry again for their discovery of polonium and radium, thus becoming the first person in the world to win the Nobel Prize twice. Madame Curie's achievements include initiating the theory of radioactivity, inventing the technology of separating radioactive isotopes, and discovering two new elements: polonium and radium. Under her guidance, people used radioisotopes to treat cancer for the first time. Due to long-term exposure to radioactive substances, Madame Curie died of malignant leukemia on July 3, 1934.
