Scott Alexander uses three fictional stories to illustrate principles of non-empirical scientific reasoning, ultimately applying them to support the many-worlds interpretation of quantum mechanics. Longer summary
This post presents three fictional stories to illustrate important points about non-empirical arguments in science. The first story shows that even when two theories make identical predictions, it's important to choose the simpler one. The second story demonstrates that determining which theory is simpler isn't always straightforward and requires philosophical understanding. The third story ties these concepts to quantum mechanics, arguing that the many-worlds interpretation is preferable to single-world interpretations based on these principles. Shorter summary

Scott Alexander reviews 'Quantum Computing Since Democritus' by Scott Aaronson, sharing insights gained despite the book's complexity and his own mathematical limitations. Longer summary
Scott Alexander reviews Scott Aaronson's book 'Quantum Computing Since Democritus', admitting he struggled to fully understand it due to its mathematical complexity. Despite this, he gained insights into quantum mechanics, computational complexity, and the nature of information in physics. The review highlights key passages and ideas from the book, including Aaronson's perspective on quantum mechanics as a generalization of probability theory and his views on artificial intelligence and consciousness. Alexander also reflects on his own mathematical limitations and the book's impact on his understanding of various scientific and philosophical concepts. Shorter summary
