Reality is not what is seems

is an excellent book by Carlo Rovelli (isbn 978-0-141-98321-9)
As usual I'm going to quote from a few pages.

It doesn't describe where there is a particle but how the particle shows itself to others.
It isn't things that enter into relations but, rather, relations that ground the notion of 'thing'.
An object is a monotonous process. [Nelson Goodman]
The sun bends space around itself, and the Earth does not circle around it drawn by a mysterious distant force but runs straight in a space that inclines.
What is conserved is the sum of mass and energy, not each separately. Processes must exist that transform energy into mass, or mass into energy.
Take the equations of quantum mechanics that determines the form of the orbitals of an electron. This equation has a certain number of solutions, and these solutions correspond exactly to hydrogen, helium, oxygen ... and the other elements!
On Mars, there are events that in this precise moment have already happened, events that are yet to happen, but also a quarter of an hour during which things occur that are neither in our past nor in our future.
Time is not universal and fixed, it is something which expands and shrinks, according to the vicinity of masses.
Suppose we want to observe a very, very, very small region of space. To do this, we need to place something in this area to mark the point that we wish to consider. Say we place a particle there. Heisenberg had understood that you can't locate a particle at a point in space for long. It soon escapes. The smaller the region in which we try to locate a particle, the greater the velocity at which it escapes. This is Heisenberg's uncertainty principle.
It isn't true that we 'do not see' Faraday lines. We only see vibrating Faraday lines. "To see" is to perceive light, and light is the movement of Faraday lines.
