As architects, builders and historians begin the process of rebuilding Notre Dame, Brian Katz, an acoustics researcher at CNRS, the Centre National de la Recherche Scientifique, and Sorbonne University in Paris, is on a mission to help restore the building’s sonic signature.
Temporary roof cover on Notre Dame
Eric Wirth, vice president of the Guild of French Architects, declared that it would be a grave mistake to rebuild the roof in anything but same wood used in its original construction. He noted its natural fire resistance. “Notre Dame has been there for 800 years. If the structure had been made of steel, there would be no cathedral to speak of today,” he said. In a fire, “iron holds for half an hour, an hour, and then writhes, pulls on the walls and collapses everything.”
Scientists with the French national research organization CNRS are embarking on a multimillion-euro effort to study the 850-year-old building and its materials with the goal of illuminating how it was constructed.
The simple answer is that we don’t know yet.
The news comes two months after the Archbishop of Paris, Monsignor Michel Aupetit, announced that a final evaluation of the damage would be concluded in Spring 2020. “We will have to encircle the scaffolding, then put a second scaffolding over it,” he said. “From this new scaffolding, workers will descend by rope and cut it bit by bit into small pieces and this will take a long time.”
You won’t find anything about Notre Dame in my podcasts (yet), they are simply poems by the late Marriott Edgar, hopefully funny. I’ve just done a new one.
A fire took hold of Notre Dame in April last year and it left an immense mess but nobody was killed. Right now in Australia bush fires are burning the country. Some people are dying and tens of thousands of people are displaced.
Climate change is happening, and happening right now.
Some people know the 1920s as the roaring twenties but for many people the 1920s were years of little money and depression. So what will the 2020s bring?
I don’t know of course, but as long as it’s not as bad as 2019 when, in April, a massive fire almost destroyed Notre Dame and later Boris Johnson was made UK Prime Minister, it might be better.
But of course as climate change takes hold, it might be worse.
