#1 I grew up reading books in my father’s bookcase, and while I was never forbidden to read them, I never saw anyone take one down. The books were massive tomes that seemed almost fused to the shelves. But the one that stood out was The Myth of Sisyphus by Albert Camus.

#2 I found it difficult to believe that scientific progress could make any difference to our assessment of life’s worth. If our experiences only paint a paltry portrait of reality, our appraisal of life would be thoroughly compromised.

#3 Modern science has shown that human experience is often a misleading guide to the true nature of reality. The most important and influential of these revisions is the understanding of space and time, which has been shaped by modern physics.

#4 Space and time are the two most important concepts in physics. They are the raw material underlying reality. Through his theories of relativity, Einstein revealed the principal role they play in the evolution of the universe.

#1

I grew up reading books in my father’s bookcase, and while I was never forbidden to read them, I never saw anyone take one down. The books were massive tomes that seemed almost fused to the shelves. But the one that stood out was The Myth of Sisyphus by Albert Camus.

#2

I found it difficult to believe that scientific progress could make any difference to our assessment of life’s worth. If our experiences only paint a paltry portrait of reality, our appraisal of life would be thoroughly compromised.

#3

Modern science has shown that human experience is often a misleading guide to the true nature of reality. The most important and influential of these revisions is the understanding of space and time, which has been shaped by modern physics.

#4

Space and time are the two most important concepts in physics. They are the raw material underlying reality. Through his theories of relativity, Einstein revealed the principal role they play in the evolution of the universe.

#5

The modern scientific age began with the work of Galileo Galilei, René Descartes, and Isaac Newton. They synthesized everything known about motion on earth and in the heavens, and in so doing, they composed the score for classical physics.

#6

The classical Newtonian worldview was pleasing. It described natural phenomena with striking accuracy, and the details of the description aligned tightly with experience. But it was not until the 1860s that the Scottish scientist James Clerk Maxwell extended the framework of classical physics to take account of electrical and magnetic forces.

#7

The relativity revolution, which addressed the first of Kelvin’s clouds, dates from 1905 and 1915, when Albert Einstein completed his special and general theories of relativity. While struggling with puzzles involving electricity, magnetism, and light’s motion, Einstein realized that Newton’s conception of space and time was flawed.

#8

The second anomaly is the quantum revolution, which was caused by the discovery that quantum laws are the only ones capable of resolving a host of puzzles and explaining a variety of data acquired from the atomic and subatomic realm.

#9

The weirdness of quantum mechanics does not stop there. It also implies that something that happens over here can be instantly linked to something that happens over there, regardless of distance.

#10

The most basic property of time is its direction, which is the opposite of forward. However, the laws of physics do not show any sign of treating one direction in time differently from the other. This is at odds with everything we experience.

#11

The big bang theory is the leading cosmological theory, which explains the origin and evolution of the universe. It was developed in the late 1960s and early 1970s, and it explains many features of astronomical observations. However, it does not explain why the universe might have been highly ordered near the very beginning.

#12

Theoretical physicists have long known that an accurate theoretical analysis of small objects, such as the observable universe when it was a mere fraction of a second old, requires the use of quantum mechanics. However, when the equations of general relativity commingle with those of quantum mechanics, the result is disastrous.

#13

The conflict between general relativity and quantum mechanics is the central obstacle to developing a unified theory. When the two theories are used in conjunction, their combined equations produce nonsensical answers.

#14

Superstring theory starts off by answering an old question: what are the smallest, indivisible constituents of matter. It claims that matter is made up of particles that are not dots but strings, and that these strings vibrate in different patterns to produce different particle properties.

#15

Superstring theory is a theory that combines general relativity and quantum mechanics into a single, consistent theory. It has revealed the breadth necessary to stitch all of nature’s forces and all of matter into the same theoretical tapestry.

#16

If superstring theory is proven correct, we will be forced to accept that the reality we have known is but a delicate chiffon draped over a thick and richly textured cosmic fabric. The discovery of extra dimensions would show that the entirety of human experience has left us completely unaware of a basic and essential aspect of the universe.

#17

The arrow of time, which is the defining feature of our everyday lives, is also central to the universe’s origin. As such, the question of time’s arrow is a common thread that runs through many of the developments in this book.

#18

I was a teenager when I read The Myth of Sisyphus, and I was hooked on the search for the deepest understanding of the cosmos. I wanted to experience life on all possible levels, not just those that were accessible to my human senses.

#19

The history of science shows that the rock of our collective scientific inquiry does not roll down the mountain. Instead, each generation takes over from the previous one, pays homage to its predecessors’ hard work and insight, and pushes up a little further.

#20

The experiment of a spinning bucket of water was performed by Sir Isaac Newton in 1689. It is still unexplained why the water’s surface takes on a concave shape as it spins. It is one of the most important steps toward understanding the structure of the universe.

#21

The concept of relativity is associated with Albert Einstein, but it goes much further back than that. It is based on the fact that velocity, the speed and direction of an object’s motion, is relative.

#22

Newton’s work on motion was met with the wrath of the Inquisition, but he was able to explain it in a way that avoided the pitfalls of previous thinkers. He introduced the bucket to explain how objects stay motionless unless something forces them to move.

#23

The water’s surface takes the shape of a concave shape when it is spinning, because the water is pressed against the side of the bucket when it spins. The only place for the pressed water to go is up.

#24

Newton explained the terrestrial bucket experiment
