Summary of Carlo Rovelli's Seven Brief Lessons on Physics

Please note: This is a companion version & not the original book. Book Preview:

#1 Einstein was a scientist who spent a year loafing around. He was in Pavia, Italy, reading Kant and attending occasional lectures at the University of Pavia. He eventually sent three articles to the most prestigious scientific journal of the period, the Annalen der Physik.

#2 Einstein’s theory of general relativity is the most complex explanation of how the world works, but it is also the simplest. It states that the gravitational field is not diffused through space; the gravitational field is that space itself.

#3 Einstein’s theory of relativity described how space curves around objects, and how time passes more quickly at higher altitudes than lower altitudes. It was a prediction that was later verified by the 1919 measurement of the sun’s deviation from straightness.

#4 The theory of relativity describes a colorful and amazing world where universes explode, space collapses into bottomless holes, time sags and slows near a planet, and the unbounded extensions of interstellar space ripple and sway like the surface of the sea.
