Ned Hall is a very good communicator. I am pleasantly surprised when a guest (yet again) does not talk at ten kajillion miles per hour. Everything is right on with this guy. He's great. I appreciate Sean stopping at times to explain. I noticed that I really needed this explanation. I also got the sense that i could get more out of the author's ideas by listening a second time. His words are nicely full of information and it's difficult for me to form an internal mental model fast enough. I find this a somewhat pleasant and slightly surprising state. This is a really good podcast. Thank's Sean! Cheers!

Thank you so much both Professors for your in-depth, scientifically meaningful and inspiring -as always- discussion. Yes !!!!! This is the real name of the game Sir Carroll... how to struck a balance between/among mindsets and senses-scapes and imagination and intuition. Happiness is pursued by the westerners, occidental folks, intellectuals if you will- like me and you both gentlemen. While how to oppose pressure of time while tackling poverty and misery is the crucial issue for Hindu people for example, for Japanese citizens and for me for instance finding a balance in life is fulfillment and joy in my idiosyncratic/spooky and agnostic world. I love versatility in people. That s why I love da Vinci/ Rennaissance type of people... I mean Gene Kelly, Judy Garland, or a concert pianist of Russian descent who is also a mathematician by profession... his name has just slip my mindscape... sorry for that. On the other side of the same coin Newton was a lonely genius so were Tschaikovsky and Balzac the writer. Being a specialized genius or a versatile guy fluent in many languages dancer and an actor may be important or not to the very person involved... all that seems much more important to the observer or/and to the audience. You have poked me Sir- so to speak- to write another sort of essay.... life cannot be boring anyway dear Professor Carroll. Have yourself a merry little Christmas... Aloha !!!!

Hume was wrong about induction because he never had the chance to read the excellent textbook Li and Vitanyi (1993) on algorithmic information theory. Modern philosophers, on the other hand, have no such excuse. Algorithmic information theory answers a huge amount of our questions about induction - its justifiability, the role of simplicity, and the number of Isaac/Scmisaac (grue/bleen) type choices we should expect to get wrong.

@@dylan9966 Let's start off with a surprising but simple fact: if you have an infinite number of things that could happen, it's mathematically impossible to expect them all equally. If you try to spread your expectation infinitely thin, it becomes equal to zero everywhere, which is equivalent to not expecting any of the options at all, which is a contradiction. Therefore, whenever you have an infinite number of things that could happen, and you try to predict the future, you're placed in this very unusual situation where if you want to predict the future at all, you have to arbitrarily pick some things as more likely than others, because assigning them all equal probability is inconsistent. This arbitrary choice is sort of like Hume's non-rational basis for induction. It's something that we didn't understand very well, and we thought we just sort of made it and hoped that *mumble mumble divine grace* or *mumble mumble evolution* steered us well. What we learned from the branch of math called algorithmic information theory is that there's a lot of structure to this choice that Hume didn't know about. If we "arbitrarily" choose to predict that simpler things are more likely than complex things, this turns out to be really good at predicting the future, and we can can quantify how good. There are an infinite number of definitions of simplicity, and we can quantify how different they are, and explain why they all suffice to produce induction. This is the sort of a priori justification for induction that Hume didn't know about because he lived before the math that makes it possible was even invented.

There is a difference between imagining that something could happen and that something actually happening. The project of science is the distinguish between the imagination and the actual. There may be an infinite number of ways of imagining that something could happen. I don't think there is an infinite number of ways that something actually could happen.

@@jjjccc728 AFAIU algorithmic information theory boils data down to strings of bits, and universes/laws of physics/models of reality to algorithms that generate those bits. I haven't checked, but it seems easy to prove that, given any finite string of bits, you can construct an infinite number of Turing machines that produce it in their output.

The main point for me is defining causality in trickier ways in terms of "possible worlds" doesn't really help with endeavors in physics but maybe helpful in social "sciences" and other quasi-scientific fields that are removed from the fundamental laws of reality by the cause-and-effect chain that is too long to be of any utility.

The Neyman-Rubin causal model (also called potential outcomes model) seems pretty strong. It's worth mentioning since it's the industry standard in some fields. Also, maybe early 20th century statisticians weren't thrilled about the concept of causality because they didn't have the statistical tools to talk about it. Someone (Fisher) had to invent the randomized trial first, right? Then people had to analyze and generalize the notion.

Hi Sean, I'm a new subscriber, but I'm familiar with your activity as a science popularizer. I have a question. We hear a lot about incompatibility of GR and QM and I'd like to know more about it. Is there a 'situation' where predictions of one cannot be reconciled with those of the other, or is it an issue of esthetics - one, GR, being essentially a classical theory (continuous, deterministic and all that) and the other being discrete and probabilistic. ,
