Experiment Series concludes with insights on London’s monument
The Lord Mayor of the City of London, Michael Mainelli, has closed his Experiment Series, a set of scientific trials that reflect his mayoral theme, “Connect to Prosper.” These experiments, which foster collaboration between academic researchers and industry experts, highlight the City’s status as a knowledge hub where academia and business unite to tackle complex challenges.
One notable experiment, “Measuring the Monument,” investigated the suitability of the Monument to the Great Fire of London as a giant telescope. While the pillar was erected to celebrate London’s recovery from the 1666 fire, it was also designed by Robert Hooke to observe the stars and measure their movements. However, findings reveal that the structure, despite its rigid design, is too susceptible to vibrations caused by wind and its height, making accurate astronomical measurements impossible.
Historically, it was believed that road traffic was the main hindrance to Hooke’s astronomical ambitions. Yet, advanced measurement techniques have shown that even moderate gusts of wind present a more significant challenge. Thus, the Monument cannot fulfil its secondary purpose as a telescope.
“The theme of this mayoralty is Connect to Prosper, celebrating the many knowledge miles that flow through our Square Mile—the world’s coffee house,” stated Mainelli. “With over 40 learned societies, 70 higher education institutions, and 130 research institutes, the City of London boasts the world’s most successful concentration of interconnected knowledge networks, where science and finance converge to tackle global challenges.”
Professor Philip Thomas, Past Master of the Worshipful Company of Scientific Instrument Makers, remarked on the collaboration among scientific instrument makers, which has clarified why Hooke abandoned his ambitious experiment.
Dr Adebayo Ogunjimi, CEO of City Optotech, emphasised the project’s alignment with the Lord Mayor’s focus on advancing scientific innovation in the City. Meanwhile, Elisabeth Jarvis from Imetrum expressed excitement over using modern measurement technologies to revive a scientific inquiry dating back over 350 years.
Enrique Gaztanaga, Professor of Astrophysics at Portsmouth University, concluded, “After 350 years, we have solved the mystery of its failure as a telescope, but the Monument stands as a testament to the scientific revolution and our quest for understanding the universe.
