Your Brain Is a Time Machine

The Neuroscience and Physics of Time

By: Dean Buonomano

Narrated by: Aaron Abano

A leading neuroscientist embarks on a groundbreaking exploration of how time works inside the brain.

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. The brain was designed to navigate our continuously changing world by predicting what will happen and when.

Buonomano combines neuroscience expertise with a far-ranging, multidisciplinary approach. With engaging style, he illuminates such concepts as consciousness, spacetime, and relativity while addressing profound questions that have long occupied scientists and philosophers alike. What is time? Is our sense of time's passage an illusion? Does free will exist, or is the future predetermined? In pursuing the answers, Buonomano reveals as much about the fascinating architecture of the human brain as he does about the intricacies of time itself. This virtuosic work of popular science leads to an astonishing realization: Your brain is, at its core, a time machine.

Time was I knew what time was.

I look forward to re-listening to this book to remember the enjoyment I feel now.
Great topic with excellent execution.

Author drowns in the flow of time

The author presents very interesting facts and data about the physics and neuroscience of time, but in the that's all the reader is left. The author fails to adequately draw a conclusion

Great book on an underrated subject

I feel obliged to admit that, like the author, I am a scientist working on the neuroscience of timing. There are not many non-fiction books about time, behavior and neuroscience and therefore I simply had to read this book. And I am glad I did.

The book begins with a summary of the psychology, philosophy, pharmacology and physiology of time. The author has an excellent grasp of the issues at stake and the importance of doing research on these topics. How do humans measure short and long time intervals? What is the shortest time interval that we can detect? How does our body know when to go to bed and get up again, and how accurate is this circadian clock? How do drugs affect our time perception, and what does that tell us about the brain? How can neurons or neural networks detect measure time? I don’t agree with everything he says about the neuroscience of timing. However, it was a joy to read these chapters and, on their own, these six chapters justified the time and money spent on this book. During my own studies, I have read tons of studies on timing employing a broad spectrum of different techniques. This book helped me connect the dots and get a bird eyes view which is something that can get lost in science.

The book sidetracked a bit in chapter seven where Buonomano takes on the physics of time and the philosophical implications. Does time even exist, or is it (like many other things), a persuasive illusion that the brain construes to give us an advantage in evolution? Is presentism (only the ‘now’ exists) or eternalism (time is another dimension and ‘now’ is to time what ‘here’ is to space) the correct model of the universe? What does our subjective sense of time tell us about time itself? These more philosophically oriented questions are taken on, at depth, and Buonomano even gets into the ‘shooting particles in moving trains’ thought experiments to explain the implications of Einstein's theory of relativity. I, perhaps naively, did not expect to encounter so much of Einstein in this book, but in the author's defense, he does an excellent job of explaining the implications of relativity, and he even manages to link it back to the psychology and neuroscience of timing.

In the last chapter, the author returns to the core issues. He discusses whether animals plan for the future (they clearly do) and whether they reflect on the future in the same way that we do (debatable). We also get to meet the Pirahã tribe who, according to an anthropologist/missionary who lived with them, lives in the here and now. They were, for instance, quite unimpressed with Christianity when they realized that their visitor had never actually met Jesus. In the last chapter, the author also takes on free will. If time is just another dimension that we can, at least in theory, travel across, then that should logically mean that everything that is going to happen has already happened which presumably means there is no free will. Free will, the author suggests may only be the feeling associated with making decisions - just like we feel pain when we get painful stimulation.

All in all, if you are interested in time and its relation to human behavior - then this book is the book is for you.

Another way to interpret thinking

Great concepts to reflect on and perhaps even act on as we become aware of how the mind works.

Comprehensive

I really appreciated the way the author addressed time from multiple perspectives and acknowledged what we don't know about the nature of time. The book is definitely accessible to the non-scientist. Would probably be best, though, to have had some introduction to the notion that all of what we perceive as "real" is a construction of the mind/brain, before wading into this book, because there is little "breaking in" of this idea, other than to acknowledge that much of our perception is an "illusion" created in/by the brain (eg, pain, color, etc.). I would definitely recommend the book to anyone who wants to wrestle with the concept of time.

Especially

interesting! Why? Because the author, just like the rest of us, really doesn't know what time is. But he did have some very interesting ideas to what makes us think we know...

Well done research, interesting topic, but...

Well done book, but it becomes one of the most repetitive books I've ever read a he must rehash the same story and concept, one specific part in at least 15 different chapters. it's a good story he keeps rehashing, but the same point/story over and over just becomes too redundant (story of how black tar heroin came to the states ). take that one point out and it's excellent. terrific writing, great investigative journalism.

amazing book!

a must listen! very complete and enticing. I highly recommend it. combines science and biology.

A '10' for Cognitive Science, a '0' for Time

Score:
Time and the Philosophy of Time: Zero
At several points I wondered how long the author could talk without saying anything of significance. You get mountains of twaddle. The author also has no clue as to what time is (a tool for tracking change). He comes close once or twice, but falls back into popular misconceptions (that time is a component of the physical world - it is not, change is).
Cognitive and Neuroscience: Ten
He does present some interesting experiments in cognitive and neuroscience, but again, weaves in the unnecessary mysticism born of not realizing what time is (a tool, and not something 'mysterious' or 'an illusion').

great research but useless for the real life

I gave 3 stars bc the author did a great job in researching, but forgot to link it to how we can use it in real life. voice is fine.
