Wilfrid Sellars described the task of philosophy as explaining how things, in the broadest sense of term, hang together, in the broadest sense of the term. (Substitute “exploring” for “explaining” and you’d have a good mission statement for the
Quantum mechanics and general relativity are the two great triumphs of twentieth-century theoretical physics. Unfortunately, they don't play well together -- despite years of effort, we currently lack a completely successful quantum theory of g
Change is scary. But sometimes it can all work out for the best. There's no guarantee of that, however, even when the change in question involves the introduction of a powerful new technology. Today's guest, Daron Acemoglu, is a political econo
Welcome to the July 2024 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 n
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 q
Evolution has equipped species with a variety of ways to travel through the air — flapping, gliding, floating, not to mention jumping really high. But it hasn’t invented jet engines. What are the different ways that heavier-than-air objects mig
I’ve been a professional physicist since the 1980’s, and not once over the course of my career has a particle-physics experiment produced a completely surprising new result. We’ve discovered particles (top quark, Higgs boson) and even phenomena
The possible existence of technologically advanced extraterrestrial civilizations — not just alien microbes, but cultures as advanced (or much more) than our own — is one of the most provocative questions in modern science. So provocative that
Time! It doesn’t stop, psychological effects of being under lockdown notwithstanding. How we experience time depends on our situation, but time itself just marches forward. Unless, of course, it’s possible to travel to the past, as countless sc
I recently saw an estimate that if you took all the novel coronaviruses in the world (the actual viruses, not patients), you could fit them into a bucket no more than a couple of liters in volume. A huge impact has been wrought by a very small
There are some problems for which it’s very hard to find the answer, but very easy to check the answer if someone gives it to you. At least, we think there are such problems; whether or not they really exist is the famous P vs NP problem, and a
There are many mysteries surrounding quantum mechanics. To me, the biggest mysteries are why physicists haven’t yet agreed on a complete understanding of the theory, and even more why they mostly seem content not to try. This puzzling attitude
For something of such obvious importance, money is kind of mysterious. It can, as Homer Simpson once memorably noted, be exchanged for goods and services. But who decides exactly how many goods/services a given unit of money can buy? And what m
It’s not easy, figuring out the fundamental laws of physics. It’s even harder when your chosen methodology is to essentially start from scratch, positing a simple underlying system and a simple set of rules for it, and hope that everything we k
If one of the ambitious goals of philosophy is to determine the meaning of life, one of the ambitious goals of psychology is to tell us how to achieve it. An influential work in this direction was Abraham Maslow’s hierarchy of needs — a list of
The human mind loves nothing more than to build mental boxes -- categories -- and put things into them, then refuse to accept it when something doesn't fit. Nowhere is this more clear than in the idea that there are men, and there are women, an
For the first full episode of Mindscape, it's an honor to welcome social psychologist Carol Tavris. Her book with co-author Eliot Aronson, Mistakes Were Made (But Not By Me), explores the effect that cognitive dissonance has on how we think. W

The germ theory of disease is a crowning achievement of science, up there with modern physics, continental drift, and evolution via natural selection. (Even if there will always be cranky skeptics.) But the road to widespread acceptance isn't a
Questions about consciousness range from the precise and empirical -- what neurons fire when I have some particular experience -- to the deeply profound -- does consciousness emerge from matter, or does matter emerge from consciousness? While i

Cosmologists were, let us be honest, pretty stunned in 1998 when observations revealed that the universe is accelerating. There was an obvious plausible explanation, the cosmological constant proposed by Einstein, which is equivalent to a const
Consciousness is easier to possess than to define. One thing we can do is to look into the brain and see what lights up when conscious awareness is taking place. A complete understanding of this would be known as the "neural correlates of consc
We often study cognition in other species, in part to learn about modes of thinking that are different from our own. Today's guest, psychologist/philosopher Alison Gopnik, argues that we needn't look that far: human children aren't simply undev
