MORE PRAISE FOR THE BIG PICTURE 01
02
‘A nuanced inquiry into “how our desire to matter fits in with the nature of 03
reality at its deepest levels,” in which Carroll offers an assuring dose of what he
04
calls “existential therapy” reconciling the various and often seemingly contra-
05
dictory dimensions of our experience.’ Maria Popova, Brain Pickings
06
‘True to the grand scope of its title...anyone who enjoys asking big questions 07
will find a lot to consider.’ Booklist 08
‘A tour de force that offers a comprehensive snapshot of the human situation 09
in our infinitely strange universe, and it does this with highly accessible lan- 10
guage and engaging storytelling.’ Salon.com 11
12
‘Carroll is the perfect guide to this wondrous journey of discovery. A bril-
13
liantly lucid exposition of profound philosophical and scientific issues.’
Kirkus (starred review) 14
15
‘From the Big Bang to the meaning of human existence, The Big Picture is
16
exactly that – a magisterial, yet deeply fascinating, grand tour through the
17
issues that really matter. Blending science and philosophy, Sean Carroll gives
18
us a humane perspective on the universe and our place in it. As gripping as it
is important, The Big Picture can change the way you think about the world.’ 19
Neil Shubin, author of Your Inner Fish 20
21
‘Until now you might have gotten away believing modern physics is about
22
things either too small or too far away to care much about. But no more. Sean
Carroll’s new book reveals how physicists’ quest to better understand the fun- 23
damental laws of nature has led to astonishing insights into life, the universe, 24
and everything.’ 25
Sabine Hossenfelder, Frankfurt Institute for Advanced Studies 26
27
‘Weaving the threads of astronomy, physics, chemistry, biology, and philosphy
into a seamless narrative tapestry, Sean Carroll enthralls us with what we’ve 28
figured out in the universe and humbles us with what we don’t yet understand. 29
Yet in the end, it’s the meaning of it all that feeds your soul of curiosity.’ 30
Neil deGrasse Tyson, host of Cosmos: A Spacetime Odyssey 31
32
‘Instead of feeling humbled and insignificant when gazing upward on a clear
starry night, Carroll takes us by the hand and shows us how fantastic the in- 33
animate physical universe is and how special each animate human can be. It is 34
lucid, spirited, and penetrating.’ S35
Michael Gazzaniga, author of Tales from Both Sides of the Brain N36
