Isn’t that what comments in the code are for?

  1. Are some categories (“whales as mammals”) more useful than others (“whales as fish”) in understanding the universe?

  2. If we categorize many different kinds of phenomena as “religion”, we might arrive at “religion is universal - present in all human cultures”, and we might then seek brain/neural mechanisms that provide an “explanation”. Whereas another approach to categorization (e.g., Lthis phenomena is no more religion than philosophy is physics”) might lead to “religion is far from universal; many cultures exist/have existed with no religion”. We mi

Yes, some categories are more useful than others for understanding the universe. Or for various other purposes. Categories more useful for one thing are not always more useful for another. (E.g., Scott's example of hypothetical-Solomon's Ministry of Dag and Ministry of Behemah; hypothetical-Solomon would not have been well served by trying to have a Ministry of Mammals instead.) The fact that some categories are more useful than others doesn't stop it being true that "the categories were made for man". It just means that our choices of categories aren't 100% arbitrary. And that's OK, because Scott is not claiming that they are.

“My soul as a computer programmer cries out against the idea of representing N particles with N^2 distances between them; it seems wasteful”

Given 3 non-collinear points on a plane, any other point is fixed by its distances from these three points; and similar results hold in higher dimensions. You need O(N) numbers, not O(N^2) numbers to describe N particles.

I have imagined that the key to scientific progress is to focus on problems that are “within reach”. If that is valid, not sure Harry has good reasons to think that solving death is within reach.

How would "within reach" be defined? One of the themes of HPMOR is Harry using the scientific method to come up with solutions that the non-scientific wizarding crowd haven't came up with. If the Laws of Thermodynamics can be transgressed in this world, solving death might not be that far-fetched of an idea.

Actually Mahatma Gandhi was very much against cowardice, not against violence. The highest courage was to resist non-violently; but if you could not do that, Mahatma Gandhi wanted you to stand your ground. Regarding WW2, he would not have India fight the Empire’s war without Independence. Not after the experience of WW1. https://arunsmusings.blogspot.com/2013/10/broken-promises-parallel.html

Agreed that the 9/11 hijackers see themselves as the heroes of their own story. But about “hating freedom”, they very likely thought that:

  1. Western influence on their cultures, regarding women’s right to dress, drive, work etc., is destructive.
  2. It is wrong that the legislatures can make laws that violate those given to them by the Prophet. (Even the alleged moderate Imam Rauf of the Ground Zero Mosque proposes that a bench of religious scholars be instituted to review decisions of the US courts).
  3. Christians and Jews must live within the limits prescribed

The Banach Tarski Paradox is a plausible way in which 1 = 2, and thus 3 = 2 + 2.

Various industry and government estimates tell us that Americans watch an unbelievable 8 hours of TV every day. Even if this a gross overestimate, what is the cost of a few days of lottery fantasy compared to that?

You might want to cite the "8 hours of TV a day" bit - if you look into houses' living room windows, you won't see TVs blaring through anywhere near a third of them. (note: this experiment is not endorsed by the author) In response to your main question: being unproductive isn't a good reason to be more unproductive.

“In many cultures, ....it is important to understand that stories are not explanations. They are neither true nor false because they do not describe ‘factual’ events; they do not claim that they do either. “

Any comments on the above?

2jeronimo196
"Neither true nor false..." Not so. We gather such stories and treasure them. But at the end of the day, we label them fiction (or mythology, if some portion of humanity believed them to be true at some point) and know better than to go looking for Hogwarts. We know fiction is not corresponding with reality, not part of the map, in other words - not true. In every sense that matter, we treat fiction as false. All that is good and proper - as long as such works don't claim to describe factual events.

Are you looking for an explanation or opinions?

I thought “emergence” talked about properties of a system which could not be localized to any of its parts.

Is “how to play the piano” part of the public, reproducible pool of knowledge of humankind?

Sayyid Qutb, who was a supplier of ideology for the terrorists who perpetrated 9/11, did see the US as evil for, among other things, the freedom of its women. (E.g., to quote Qutb via Wiki, he noted the “animal-like" mixing of the sexes (which "went on even in churches")). So “hate our freedom” has truth to it.
