Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium.

the french revolution main idea was to give power to the people. the revolution was influenced by the enlightenment ideas, reasoning and skepticism pushed people to revolt against standards and norms in french society.

the problem was that the revolution caused political turmoil, and napoleon saw this as an opportunity and launched a coup d’état in november 1799. he became the first consul of france and later named french emperor.

some people see napoleon as a hero of the revolution and others see him as a traitor.

people see him as a traitor because he noticed the political turmoil and used this moment to rise to power. others see him as a hero of the revolution because he had some political and military achievements - in which he was committed to promoting the achievements of the french revolution - he had extensive public constructions, made a civil reform.

in a bigger picture, napoleon had some huge achievements in france which made him very important, but the fact that he seized power to himself makes him an undeniable traitor to the revolution since the main idea of it was to remove people from power and give power to the people.
