Einstein's genius preserved in a blackboard at Nottingham University

In the United Kingdom, a unique blackboard holds significant historical value as it features both scientific notations and the signature of Albert Einstein. This blackboard is the only known one of its kind in the world, representing a personal touch from one of history's greatest scientific minds. It remained untouched since 1930, when Einstein visited Nottingham University to deliver a speech. This event was notably shaped by his relationship with the university's head of physics, Henry Brose, who had previously been interned with Einstein in a camp during World War I. On the day of the event, Einstein was delayed as he visited Isaac Newton's birthplace, causing a large crowd to gather. After his speech, the blackboard was intentionally left partially un-wiped to preserve the marks of Einstein’s chalk writing, making it a direct link to the genius's thoughts. Additionally, someone took the piece of chalk he used, which is now wrapped in string to prevent it from being touched. This blackboard emphasizes the importance of recognizing scientists as real individuals with personal stories behind their ideas. According to Antonio Padilla, a professor of physics at Nottingham, understanding the people behind great ideas is vital for young scientists. He believes that students should learn about Einstein not just as a figure but as a person who overcame significant challenges to achieve his status. Almost 95 years later, this remarkable artifact is kept under glass in a meeting room at Nottingham University's physics building, although very few people, including students, are aware of its existence and significance.
