Paolo Giordano, the author of the best-selling book "The Solitude of Prime Numbers", a theoretical physicist, decided to do what he does best in quarantine: to fix the moment after which our world will most likely not be the same. The result: an essay about the virus that will help each of us calm down.What is the coronavirus, where did it come from, how can we resist it, why are we all uneasy – and how do we keep calm? And, most importantly, what can this disease tell us about ourselves? These are the questions that a writer from the heart of the pandemic, Rome, answers."I'm not afraid of getting sick. What am I afraid of? How our lives can change. That the building of the civilization I know will collapse like a house of cards. I am afraid that our familiar world will be swept away without a trace, but at the same time I am afraid of the opposite: that my fear will be in vain and nothing will change in the world."
