The Earth's atmosphere is good for some things, like providing something to breathe. But it does get in the way of astronomers, who have been successful at launching orbiting telescopes into space. But gravity and the ground are also useful for certain things, like walking around. The Moon, fortunately, provides gravity and a solid surface without any complications of a thick atmosphere -- perfect for astronomical instruments. Building telescopes and other kinds of scientific instruments on the ...

Complexity scientists have been able to make an impressive amount of progress despite the fact that there is not universal agreement about what "complexity" actually is. We know it when we see it, perhaps, but there are a number of aspects to the phenomenon, and different researchers will naturally focus on their favorites. Today's guest, David Krakauer, is president of the Santa Fe Institute and a longtime researcher in complexity. He points the finger at the concept of agency. A ba...

Welcome to the July 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic. We're experimenting with a new benefi...

Last year's Nobel Prize for experimental tests of Bell's Theorem was the first Nobel in the foundations of quantum mechanics since Max Born in 1954. Quantum foundations is enjoying a bit of a resurgence, inspired in part by improving quantum technology but also by a realization that understanding quantum mechanics might help with other problems in physics (and be important in its own right). Tim Maudlin is a leading philosopher of physics and also a skeptic of the Everett interpretation. We disc...

It's somewhat amazing that cosmology, the study of the universe as a whole, can make any progress at all. But it has, especially so in recent decades. Partly that's because nature has been kind to us in some ways: the universe is quite a simple place on large scales and at early times. Another reason is a leap forward in the data we have collected, and in the growing use of a powerful tool: computer simulations. I talk with cosmologist Andrew Pontzen on what we know about the universe, and how s...

There is an image, especially in Western cultures, of the rugged, authentic, self-made individual choosing how to navigate the intricacies of the social world. But there is no mystical soul within us, manifesting as the immutable essence of self. What we think of as our "self" is shaped by our environment and our genes, and most of all by our interactions with other people. Psychologist Brian Lowery argues for a strong version of this thesis, positing that our sense of self is largely a social c...

Modern computers are somewhat more secure against being hacked - either by an inanimate virus or a human interloper - than they used to be. But as our lives are increasingly intertwined with computers, the dangers that hacking poses are enormously greater. Why don't we just build unhackable computers? Scott Shapiro, who is a law professor and philosopher, explains why that's essentially impossible. On a philosophical level, computers rely on an essential equivalence between "data" and "code," wh...

The modern world is large and interconnected, and there are a lot of systems that might be important to how it functions but about which most people are barely aware. One of these is the offshore wealth management network, which wealthy individuals can use both legitimately (to invest and plan their money) and less legitimately (to avoid taxation or hide questionable practices generally). Brooke Harrington is a sociologist who has studied offshore wealth management, including by training to be o...

Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today's guest, Thomas Hertog, is a physicist and longstanding collaborator of S...

What is the mind, and what does it try to do? An overly simplified materialist view might be that the mind emerges from physical processes in the brain. But you can be a materialist and still recognize that there is more to the mind than just the brain: the rest of our bodies play a role, and arguably we should count physical artifacts that contribute to our memory and cognition as part of "the mind." Or so argues today's guest, philosopher/cognitive scientist Andy Clark. As to what the mind doe...

Eukaryotic cells manage to pull off a number of remarkable feats. One is packing quite a long DNA molecule, with potentially billions of base pairs, into a tiny central nucleus. A key role is played by histones , proteins that provide scaffolding for DNA to wrap around. Histones also appear in archaea (one of the other domains of life), but until recently there wasn't evidence for them in bacteria (the final of the three domains). Todays guest, Tobias Warnecke, is an author on a rece...

Here at the Mindscape Podcast, we are firmly pro-reason. But what does that mean, fundamentally and in practice? How did humanity come into the idea of not just doing things, but doing things for reasons? In this episode we talk with cognitive scientist Hugo Mercier about these issues. He is the co-author (with Dan Sperber) of The Enigma of Reason , about how the notion of reason came to be, and more recently author of Not Born Yesterday , about who we trust and what we believe. He a...

If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage. Economist Amy Finkelstein is an expert in this phenomenon, as well as...

Human beings are small compared to the universe, but we're very important to ourselves. Humanism can be thought of as the idea that human beings are themselves the source of meaningfulness and mattering in our lives, rather than those being granted to us by some higher power. In today's episode, Sarah Bakewell discusses the origin and evolution of this dramatic idea. Humanism turns out to be a complex thing; there are religious humanists and atheistic anti-humanists. Her new book is Humanl...

Every time our brain does some thinking, there are associated physical processes. In particular, electric currents and charged particles jump between neurons, creating associated electromagnetic fields. These fields can in principle be detected with proper technology, opening the possibility for reading your mind. That technology is currently primitive, but rapidly advancing, and it's not too early to start thinking about legal and ethical consequences when governments and corporations have acce...

God is dead, as Nietzsche’s madman memorably reminded us. So what are we going to do about it? If there is no powerful force out there to guide us and give meaning to our lives, how are we supposed to live? Do we have to come up with meaning and purpose ourselves ? Apparently so, and how to pull it off was a major question addressed by the existentialist movement. Skye Cleary turns to Simone de Beauvoir, in particular, for thoughts on how to construct an authentic life. Her recent book is&...

Most of us strive to be good, moral people. When we are doing that striving, what is happening in our brains? Some of our moral inclinations seem pretty automatic and subconscious. Other times we have to sit down and deploy our full cognitive faculties to reason through a tricky moral dilemma. I talk with psychologist Molly Crockett about where our moral intuitions come from, how they can sometimes serve as cover for bad behaviors, and how morality shapes our self-image.

Cities are incredibly important to modern life, and their importance is only growing. As Geoffrey West points out, the world is adding urban areas equivalent to the population of San Francisco once every four days. How those areas get designed and structured is a complicated interplay between top-down planning and the collective choices of millions of inhabitants. As the world is changing and urbanization increases, it will be crucial to imagine how cities might serve our needs even ...

Human beings have developed wondrous capacities to take in information about the world, mull it over, think about a suite of future implications, and decide on a course of action based on those deliberations. These abilities developed over evolutionary history for a variety of reasons and under a number of different pressures. But one crucially important aspect of their development is their social function. According to Michael Tomasello, we developed agency and cognition and even mo...

So you have some information — how are you going to share it with and present it to the rest of the world? There has been a long history of organizing and displaying information without putting too much thought into it, but Edward Tufte has done an enormous amount to change that.

There are few human impulses more primal than the desire for explanations. We have expectations concerning what happens, and when what we experience differs from those expectations, we want to know the reason why. There are obvious philosophy questions here: What is an explanation? Do explanations bottom out, or go forever? But there are also psychology questions: What precisely is it that we seek when we demand an explanation? What makes us satisfied with one? Tania Lombrozo is a psychologist w...

Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it’s only inspiration, not detailed guidance. So it’s easy to “do research on quantum gravity” and get lost in a world of toy models and mathematical abstraction. Today’s guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world. We talk...

One of the most powerful of all human capacities is the ability to imagine ourselves in hypothetical situations at different times. We can remember the past, but also conjure up possible futures that haven’t yet happened. This simple ability underlies our capability to organize socially and make contracts with other people.
