Difficult start

Difficult start

Dmitrij was born in 1834 and was raised in Siberia with more than 10 brothers and sisters.

His mother after compliting her mission, promptly died. Undeniably, Dmitrij felt a tremendous debt to his mother and wanted her to be proud of him. Maybe this is one of the reasons why

When he was 13 years old his father passed away leaving the family destitute. His mother, in order to support family, decided to re-open abandoned glass factory, which burnt down a few years later.

Dmitrij Ivanowich Mendeleev became one of the crown jewel of russian science

His mother was the only one who saw his potential.

One day she packed his belongings, left the family on their own and rode 1200 miles with him on the horseback to he university in Moscow. Unfortunately he was rejected. Then they rode another 400 miles to S.Petersburg to the school where his father had graduated and he was accepted this time.

Massive slab of human genius

Mendelejew with few other scientists found out that the relationship between elements is periodic. They created a table where list of elements characteristic repeat every seven elements. But it wasn't perfect either. Other scintists said nothing is perfect and we should accept this.

At 1860 only about 60 elements were known to a mankind. It was sorted in order their atomic weights. But soon it was realized that the most significant relationships between elements has nothing to do with their atomic weights.

But not Mendelejew

Mendelejew inserted gaps into the table (elements which hadn't been discovered yet). When he did it suddenly everything fell perfectly into place. He created a periodic table which we now use

Mendeleev's genius

Suprisingly, he didn't make a list of all known elements because many other scientists had done this before him. What is more, he wasn't the first one who arranged elements with similar properties togeher. So what setss him apart from many other scientists?

He actually knew the data better than anyone else. He was so certain that was even able to predict properties of missing elements

He was the only one who realized that the idea of periodicity had far reaching consequences

He was obsessive. He never gave up ene when everyone else did. Mendeleev spent a ton of time working on his theory and had a deep belief of importance of what he was doing.

Invaluable reward

Scientists from UC Berkeley discovered previously undiscovered element and it filled an empty spot at number 101. In 1963 this element was oficially named Mendelevium

Mendeleev never really got win the Nobel Prize. More suprisingly, during his lifetime six scientists were awarded. He was nominated in 1905, 1906 and 1907 but lost because a committee member thought his work was too old and well-known.

There have been over 800 Nobel Prize winners

but only 15 of them have an element named after them

Why do we need it?

The periodic table which we know and use it's a represantation of reality, way of understanding and sorting the universe

We can think of a universe as a collection of puzzle pieces. For centuries humans have tried to discover what makes up the world around them. It's fair to say that the discovery of these pieces revolutionalized our understanding of the world.
