Summary

TLDRDimitri Mendeleev, born into poverty in Siberia, overcame adversity to become a renowned chemist. His dedication led to the creation of the periodic table, arranging the 63 known elements by atomic weight. His insight identified gaps, predicting elements yet to be discovered, showcasing his genius and the importance of gaps in scientific discovery.

Takeaways

🌍 Dimitri Mendeleev was from Siberia, a remote region of the former Zaris Empire.
👨‍👩‍👧‍👦 He was the last of 17 children and his family lived in extreme poverty.
👀 His father went blind and died, leaving the family in a dire situation.
👩‍🏫 His mother made great sacrifices to ensure Mendeleev received an education.
🎓 Through his mother's efforts, Mendeleev was eventually accepted into a university in St. Petersburg.
🧠 As a young man, Mendeleev was known for his quick mind, quick temper, and determination.
🔍 He was dedicated to understanding the relationships between the 63 known elements at the time.
🃏 He used a deck of cards to organize elements by atomic weight and tried to find a pattern.
💤 Mendeleev had a dream that helped him see the pattern, leading to the creation of the periodic table.
🔑 He arranged the elements in order of increasing atomic weight and grouped them into families.
🔮 Mendeleev predicted the existence of elements that would fill gaps in his table, which were later discovered.
