Marie challenged authority by leaving Poland and traveling to France to enter the Sorbonne because, at the time, women were not allowed to attend universities in Poland. Despite this societal barrier, Marie was determined to pursue her education. Instead of accepting the limitations placed on her due to her gender, she defied the educational and social constraints of her homeland and took the bold step of moving to France, where she could study at the prestigious Sorbonne. This act of independence and determination challenged the prevailing norms and expectations for women at the time, reflecting her drive for knowledge and her refusal to accept restrictions based on her gender.
