I came in the comments section with the intent of asking HN about generalized divisibility rules for any number N with any base B. Looks like you provided the goods.

I will believe that the market is truly free when I see multiple start-ups attempt to upend Apple's business model and fail to do so.

I completely agree with this. Ancient philosophers debated the existence of atoms for centuries; then Boltzmann took the theory up to second gear by discovering the implications on temperature and entropy, and then Einstein proved their exi

I am not a fan of these types of proofs. Baez didn't explain how one would go about searching for this proof, he just happened to know that repeatedly using the differential operator on a seemingly random differential equation would cr

I'm in the exact same boat as you are. Right now, I'm doing my best to work with FreeCAD, but Blender3D has an interesting precision-modelling plugin that makes for a somewhat complicated but reliable alternative. You're goin

Journals are where scientists present any sort of evidence that is backed by sound reasoning, meta-studies are where overwhelming evidence tends to be presented. If it were any other way, then where would scientists publish underwhelming ev

I think the parent comment meant to say that once you see the answer to one of the questions, the question seems easy and simple in retrospect (i.e. the questions are NP hard, in a certain respect). That's the fact that is usually tout

Exactly. Just imagine the quantum world as a bunch of liquids floating around carrying their associated particles, and you have an intuitive grasp of (the debroglie bohm interpretation of) quantum physics.

1. My link stated that in certain areas, such as Connecticut, traffic fatalities went up. 2. My overall point is that a certain number of excess deaths are atrributable to the lockdown itself, rather than Covid. IIRC, the total number of re

But then we get to the question of whether those deaths were caused by COVID or other causes. We know that traffic fatalities in some areas have risen drastically due to the lockdowns: https://abc7.com/traffic-fatalities-cal

Thermal power requires a reservoir of cold temperature; your car's engine would do nothing if the incoming air was just as hot as the post-ignited air.

The supply chain makes no distinction between people who buy hand sanitizer for $2 in Tennessee, and people who buy hand sanitizer for $2 in New Jersey, but are desperate enough to pay $20 for it. The supply chain has no incentive to redire

So by your own admission, the carbon cycle contains producers. So it is not a lie to point out that human emissions are a small percentage of total emissions. Bringing up the rest of the information about the carbon cycle does not turn the

I don't know what the original commenter said, or whether it deserved to be flagged, but it's undeniably true that human emissions only account for 5% of the planet's total emissions.

The economy cannot be modelled as a linear system; it is a pseudo-chaotic system. If one poorly-chosen element is labelled as a "non-essential business", it can cause all the other metaphorical Jenga blocks to collapse.

My next project: 1) gather SEC income statements sorted by industry, sector, and year. 2) gather death statistics, sorted by cause and year. 3) create a model of deaths as a function of parts of the economy shutting down. 4) create a model

The rate you're referring to must be (number of deaths)/(number of cases). That rate is low, but the denominator grows at astronomical speed; evidence of the high numerator is going to show up eventually.

Hmmm. If only there was a way to incentivize food producers to produce more food while disincentivizing consumers from buying too much food. Something like what economists refer to as a "price", that can be raised during shortages

I'm not the OP, but the world just lost hundreds of trillions of dollars of wealth over the past month. When people start going hungry because of a lack of income, then we can really start comparing the harm of containment to the harm
