The Order of Time is a brilliant book on quantum physics explained in a simple and beautiful way. Professor Rovelli not only guides us through a complex theme that is quantum, as he quotes poetry that is somehow related with the concepts of the book. The main subject, as the title indicates, is time. How time behaves, what is time, how it affects us, how we perceive it, ultimately, how it affects reality.
Some of the most interesting points that Professor Rovelli brings up are:
-
The relativity of time towards a body mass: how time passes differently in the mountains and at sea level due to the proximity to the Earth’s core.
-
The relativity of time towards movement: how moving around affects the perception of time.
-
How the world is made of events and not of things. It is made of something that occurs, not of objects or the shape of a thing at a specific moment.
-
Why present is relative and it only exists on Earth.
-
Our perception of time and reality, past and future, and how these are not a straight line.
-
How language affects our perception of time, past and future and, consequently, our difficulty to understand its relativity.
-
What entropy actually means in terms of time/reality/energy and its importance.
It really is a very clarifying book with an interesting light on the subject. Professor Rovelli is not only an outstanding physicist, as he has the soul of a poet and he is able to connect with the reader from the first line.
For all these reasons, The Order of Time was one of the most brilliant books I’ve ever read. I highly recommend it to anyone who wishes to understand more about who and what we are as human beings experiencing life on Earth in this form and why time is an undeniably huge part of it.
