Today on EconTalk, physicist and author Alan Lightman joins host Russ Roberts to discuss his latest book, “The Miraculous from the Material: Understanding the Wonders of Nature.” This marks Lightman’s third appearance on the show, with his previous visit in April 2020 focusing on stardust, meaning, religion, and science.
In the interview, Lightman clarifies his distinction between miracles and the miraculous. While he does not believe in miracles, which he defines as events that contradict our current understanding of natural laws and often involve supernatural intervention, he does believe in the miraculous. By the miraculous, Lightman refers to the awe-inspiring beauty and order found in nature, such as rainbows, flowers, shooting stars, and spider webs.
Lightman emphasizes the importance of paying attention to the natural world and fostering a sense of awe in children and grandchildren. He notes that in today’s digitized and fast-paced society, many people are more focused on technology and communication devices than on the natural world around them. Encouraging children to spend time in nature and to pay attention to their surroundings can help cultivate a sense of wonder and appreciation for the beauty of the world.
In response to the argument that scientific explanations have diminished the sense of awe in the natural world, Lightman offers a different perspective. He believes that understanding the scientific principles behind natural phenomena, such as the formation of Saturn’s rings or the distance of stars, does not diminish their beauty or the emotional reactions they evoke. Despite our knowledge of how these phenomena occur, we can still experience awe and appreciation for their magnificence.
Lightman suggests that our emotional responses to the beauty of nature stem from a primitive part of the brain, the amygdala, which has evolved over millennia to respond to stimuli in the environment. This ancient part of the brain still allows us to feel wonder and awe when we encounter the wonders of the natural world, even when we understand the scientific explanations behind them.
Overall, Lightman’s book and discussion with Roberts highlight the importance of maintaining a sense of awe and appreciation for the beauty and order found in nature, even as scientific knowledge advances. By taking the time to pay attention to the world around us and to marvel at its wonders, we can cultivate a deeper connection to the natural world and experience the miraculous in our everyday lives.
Desimone believes that it is a computing challenge and that eventually, with enough data and processing power, we could potentially predict such things. He believes that the brain is ultimately a machine that follows certain rules and patterns, and that given enough information about a person’s brain and their environment, we could predict their future actions and feelings.
However, I personally feel that there may be a philosophical barrier to truly understanding and predicting human emotions and experiences. While science has made tremendous progress in understanding the physical world, there is still so much about the human mind and consciousness that remains a mystery.
There is something inherently mysterious and ineffable about human experiences like falling in love or feeling awe when looking at the night sky. These are deeply subjective and personal experiences that may not be reducible to mere data and algorithms.
It’s possible that there are aspects of human consciousness that will always remain beyond the reach of science, no matter how advanced our technology becomes. The human mind is a complex and enigmatic entity, and there may always be aspects of it that elude our understanding.
Ultimately, I believe that while science can provide us with valuable insights into the physical world, there are limits to what it can fully explain when it comes to the complexities of human experience and emotion. And perhaps, that is a good thing. The mystery and wonder of our own consciousness may be one of the things that make life truly beautiful and meaningful.
In a recent conversation between Russ Roberts and Alan Lightman, the topic of artificial intelligence (AI) and neuroscience was brought up, specifically in relation to the ability to predict human emotions and consciousness. Lightman explained that with advancements in technology and neuroscience, it may be possible for a neuroscientist working with AI to predict with a high level of probability who a person may fall in love with, based on interviews and brain examinations. He mentioned that as technology and neuroscience progress, these probabilities may become more accurate.
However, Lightman raised an important question about whether computers can truly capture the essence of human emotions, known as qualia. He referenced philosopher Thomas Nagel’s work, “What Does it Feel Like to Be a Bat?”, which argues that it is impossible for one organism to truly know what it feels like to be another organism. While computers may exhibit behaviors associated with consciousness, such as self-awareness and future planning, it does not necessarily mean they are conscious in the way humans are.
The conversation then shifted to the topic of whether computers can ever be truly conscious. Lightman shared his view that while computers may exhibit all the attributes associated with consciousness, it does not guarantee that they truly experience consciousness. He emphasized the importance of understanding what it feels like to be a computer in order to determine its level of consciousness.
Roberts brought up the example of his experience in a driverless car, pondering whether the car has any regrets or desires given its lack of consciousness. He also discussed the complexity of defining love and how it evolves over time, highlighting the challenge of quantifying such deeply personal experiences.
Ultimately, Lightman agreed that certain phenomena, such as love, may be beyond the scope of scientific explanation. He emphasized the value of consulting experts in various fields to ensure accurate and well-rounded explanations, acknowledging the limits of his own expertise. The conversation underscored the intricate relationship between science, technology, and the human experience, raising thought-provoking questions about the nature of consciousness and emotions in the age of AI.

Despite various theories surrounding ball lightning, its exact nature remains a mystery, adding to its intrigue and wonder.
The conversation also touches upon the rarity of ball lightning, as highlighted by a legal case in Tennessee where Lightman was consulted as a witness due to his expertise on the subject. The loud bang produced by the explosion of ball lightning is discussed, with Lightman noting that while it was loud, it did not leave any physical marks or scars in his house. He was alone during the incident, but his wife, who was in the house at the time, also witnessed the phenomenon, confirming his experience.
Overall, the article emphasizes the curiosity and wonder that writing a book can bring, particularly when delving into unknown or little-understood phenomena. The process of research and exploration that comes with writing allows authors to uncover new knowledge and insights, leading to a greater appreciation and understanding of the world around us. “Close Encounters of the Third Kind” is a classic Spielberg film that delves into the mysterious world of UFO sightings and encounters with otherworldly beings. In a recent conversation between Alan Lightman and Russ Roberts, the topic of the film came up, sparking a discussion about the nature of supernatural phenomena and the conservative approach of science in accepting such events.
The film revolves around the idea of encountering beings from another world and the challenges faced by those who claim to have witnessed such events. One of the key points raised in the conversation was the frustration and disbelief that often accompanies such encounters. The idea that people would not believe you if you claimed to have seen aliens adds a layer of complexity to the narrative, highlighting the skepticism and cynicism that often surrounds these types of events.
Lightman and Roberts also touched on the scientific approach to these phenomena, emphasizing the need for reproducibility and evidence in order to validate such claims. While science has brought about many advancements and technological innovations, it also imposes strict criteria for accepting new ideas and experiences.

The idea that animals use color to signal their poisonous nature and deter predators was also examined, shedding light on the intricate mechanisms of natural selection and evolution.
Overall, the conversation between Lightman and Roberts provided a thought-provoking exploration of the themes and concepts present in “Close Encounters of the Third Kind,” offering a deeper understanding of the film and the broader implications of supernatural encounters. If it works that well, it must be fascinating. Alan Lightman, a renowned physicist and writer, delves into the intricacies of nature and science in his discussions with Russ Roberts. From the limitations of mountain heights to the astonishing number of lightning strikes on Earth, Lightman sheds light on the wonders of the world around us.
One of the most intriguing topics discussed is the height limitations of mountains, particularly Mount Everest. Lightman explains that as a mountain gets higher, the pressure at its base increases, eventually liquefying the ground underneath it. This phenomenon restricts the height of mountains, as the mountain loses its solid foundation. Planets with lower gravity, like Mars, can have taller mountains due to less pressure at the base.
The conversation then shifts to hummingbirds, known for their rapid wing flapping. Lightman discusses how their high metabolism and energy needs limit their lifespan. The movement of their wings generates heat, which their bodies must efficiently dissipate. This efficient heat dissipation is crucial for their survival in warm climates.
Lightning strikes are another fascinating topic, with Earth experiencing about 9 million strikes per day. While this number may seem implausible, it is based on visible lightning bolts recorded by weather stations worldwide. Lightman explains that extrapolating data from well-recorded areas allows for an estimation of lightning strikes in other regions.
Saturn’s 146 moons spark curiosity, with Lightman revealing that Earth’s moon is not the largest. The abundance of moons around Saturn is attributed to the formation of planets from a gas cloud during the early days of our solar system. Collisions between fragments and varying conditions around each planet contributed to the diverse moon populations.
As Lightman and Roberts explore these scientific marvels, they provide a glimpse into the complexity and beauty of the natural world. Their discussions highlight the interconnectedness of various phenomena and showcase the mysteries waiting to be unraveled by curious minds. If it works that well, the world truly is a remarkable place. Saturn, the beautiful planet known for its majestic rings, has always captured the curiosity of astronomers and space enthusiasts. The rings of Saturn, made up of debris from the formation of the solar system, have long been a subject of fascination and study. But what about Saturn’s moons? Are they just as intriguing as the planet itself?
One interesting fact about Saturn’s moons is that our very own moon is not the largest moon in the solar system. In fact, Saturn’s moon Titan holds that title. The classification of moons and planets is somewhat arbitrary, with moons generally being smaller bodies that orbit larger planets. And if a planet grows large enough, it can even become a star. For example, Jupiter, the largest planet in our solar system, could have potentially become a star if it had been 10 times more massive.
In a recent discussion between Russ Roberts and Alan Lightman, the topic of consciousness and intelligence in the universe was brought up. Lightman expressed his belief that consciousness is a graded phenomenon, with varying levels of awareness and mental capability across different species. While animals like crows and dolphins exhibit a high level of consciousness, smaller organisms like amoebas likely do not possess consciousness in a meaningful sense.
When it comes to the universe as a whole, the idea of a collective consciousness or group intelligence was also explored. Some people believe that human civilization, with its art, science, and culture, constitutes a form of group consciousness. However, Lightman argued that the strong sense of individuality that humans possess suggests that true independence and separateness exist among individuals, despite any perceived connections or shared experiences.
Ultimately, the discussion delved into the philosophical and metaphorical implications of consciousness and interconnectedness in the universe. While the idea of a collective consciousness may hold a certain romantic appeal, the reality of individuality and independence remains a fundamental aspect of human existence. As we continue to explore the mysteries of the cosmos, the questions of consciousness and intelligence in the universe will undoubtedly remain a source of fascination and contemplation for years to come. The discussion between Alan Lightman and Russ Roberts delves deep into the human need for belonging and the desire for order in the universe. Lightman, reflecting on our evolutionary past, highlights the importance of interdependence in early human communities for survival. The sense of connection to others and the need for belonging were crucial aspects of our ancestors’ lives, ensuring that individuals stayed close to their group for protection and sustenance. This inherent need for social connection and community has been ingrained in our brains through natural selection, shaping our relationships and interactions with others.
Lightman’s perspective offers a scientific explanation for the human desire for belonging and the appreciation of beauty. He emphasizes that these feelings and values have evolutionary origins, rooted in our animalistic nature. Despite our capacity for art, science, and philosophy, we are ultimately animals connected to other species on Earth. Lightman’s insights provide a unique perspective on the human experience, highlighting the interconnectedness of all living beings.
Roberts adds a personal touch to the conversation, reflecting on his upbringing in Memphis and the influence of his parents’ accents on his own speech. He draws parallels between the need for belonging and the desire for order in human society, pointing out our fascination with causation and explanation. Roberts mentions the Sistine Chapel as a prime example of human creativity and intention, showcasing the beauty and complexity of human artistry.
The conversation touches on the inherent human desire for order and predictability, while also acknowledging the importance of unpredictability and spontaneity in life. Lightman and Roberts explore the balance between structure and chaos, highlighting the complexity of human existence and the mysteries of the universe. As they discuss the interconnectedness of all living beings and the beauty of creation, they offer a thought-provoking reflection on the nature of humanity and our place in the world. When discussing the intricacies of the human mind, one cannot ignore the fascinating aspect of our preference for a balance between order and chaos. Just like in art, where a perfectly symmetrical painting might not hold our attention for long, our minds seem to crave a touch of asymmetry or unpredictability to keep things interesting.
