🎓Последний (так принято считать) ученый-энциклопедист поражал диапазоном своих талантов. Химия, физика, география, метрология и метеорология, педагогика — сложно перечислить всё, что интересовало Менделеева.

Однако было в жизни Менделеева то, что он считал главным. Почти 40 лет жизни гения (5 лет учебы и 33 года преподавания) связаны с Императорским Петербургским университетом. Конечно, образование и преподавание были очень важны для сына директора Тобольской гимназии.
Отметим, что именно в университетских лабораториях сделаны главные открытия Менделеева в области химии и физики.

На памятном блоке известный портрет русского ученого размещен на фоне здания Императорского Петербургского университета и библиотеки, расположенной в университетском кабинете Менделеева.

Кстати, в 2024 году, помимо 190-летия Д.И. Менделеева, научный мир отмечает и 155-летие открытия Периодической системы химических элементов.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
