1. Bruno: Expanded Copernicus’ heliocentric theory and was burned at the stake.

2. Marie Curie: studied radioactive elements and suffered from cancer (leukemia).

3. Deng Jiaxian: The hero of the two bombs. He was exposed to nuclear radiation and suffered from rectal cancer. Unfortunately, he died at the age of 62.

4. Hippasos: Discovered that the irrational number root 2 cannot be expressed as the quotient of two positive numbers, which led to the first mathematical crisis in the history of Western mathematics. ?The discovery of irrational numbers expanded the concept of numbers another step. Hippasos himself was punished for violating the creed of "proportionality" and was thrown into the sea and drowned.

5. Galileo: Agreeing with Copernicus’s proposition, he was interrogated without restrictions and was not placed under house arrest and lost his freedom.

Extension of Marie Curie’s knowledge:

Marie Curie (November 7, 1867 - July 1934) 4), born in Warsaw, known as "Madame Curie" in the world, her full name is Maria Sk?odowska Curie (Maria Sk?odowska Curie), a famous French Polish scientist, physicist, and chemist.

In 1903, the Curies and Becquerel won the Nobel Prize in Physics together for their research on radioactivity. In 1911, they won the Nobel Prize in Chemistry again for the discovery of the elements polonium and radium. Thus becoming the first person in the world to win two Nobel Prizes. Marie Curie's achievements include pioneering the theory of radioactivity, inventing technology for separating radioactive isotopes, and discovering two new elements, polonium and radium. Under her guidance, radioactive isotopes were used for the first time to treat cancer. Due to long-term exposure to radioactive substances, Marie Curie died of malignant leukemia on July 3, 1934.
