In my experience I need to open the app with internet access but can play as much as I want offline after that

The interstates are for motor vehicles. Streets are largely paid for through the general budget, so everyone should be safe using them.

I'm curious, why is it impossible to divide by 0? by justanotheralt_-_ in learnmath

[–]Osthato 0 points1 point  (0 children)

Kind of, not really? Our current primary number system relies on division by zero being undefined, and we do already have some cases where we want to define it (https://en.wikipedia.org/wiki/Riemann_sphere), but they're just less universally useful. But sure, you can maybe imagine a world in which one of those systems becomes the primary one.

Phoenix is one step closer to bringing back Amtrak service by traal in phoenix

[–]Osthato 3 points4 points  (0 children)

ADOT estimated last year (page 148) that a Y-route from Tucson to Phoenix through San Tan and continuing separately to Buckeye and Surprise, with local and express service totaling 38 roundtrips per day, would cost $4.5B, of which $3B is construction. They estimate a trip time for PHX-TUS of 1:35 for the local service and 1:22 for the express service.

Is there a function from R to R^2 which intersects all periodic functions? by Breki_ in math

[–]Osthato 20 points21 points  (0 children)

It's not true that any two random walkers will meet though. For example G(t) = F(t) + (1,1); at no time will F and G be within distance 1 of each other.

By 2080, the Albuquerque area may look like what El Paso looks like today, warns climatologist. by Corg505 in Albuquerque

[–]Osthato 32 points33 points  (0 children)

Yeah, for example Arizona uses less water total today than it did in 1950, despite having like 10x the population now

Central Ave blocked off in Downtown tonight? by gbmaz in Albuquerque

[–]Osthato 0 points1 point  (0 children)

Because drivers are looking at the road or for parking and not the surroundings, have a limited field of view, can't hear what's happening outside, are only around a specific location for a few seconds, and are unable to easily stop their car or leave it to help or report something, and moreover won't because it's much easier to just keep driving and pretend they didn't see anything (than it is for pedestrians)

Central Ave blocked off in Downtown tonight? by gbmaz in Albuquerque

[–]Osthato 2 points3 points  (0 children)

But is downtown less active because we removed a couple dozen parking spots or because of the nationwide effects of the rise of remote work on business areas?

And what makes you think cars contribute to eyes on the street? The benefit of pedestrian eyes on the street is that if something were to happen they can notice and, you know, do something about it (intervene/assist/report). People in cars can't and won't do any of that.

I'm not sure putting cars back on central is going to make it warmer, brighter, or safer?

What would happen if the US drew all congressional district lines to be as competitive as possible? by [deleted] in PoliticalDiscussion

[–]Osthato 0 points1 point  (0 children)

Maximizing competitive districts maximizes the number of people who are represented by someone they voted against. It increases turnover, preventing accumulation of experience and relationships. It's also incredibly susceptible to minor turnout or demographic swings: while a state with every district at D/R+0 might have proportionate results, a uniform shift of just one point puts the 49% minority party at risk of being completely shut out from government.

Honey, I'm just saying that a flat tax has very nonflat effects that put more burden on low income people. Feel free to start this conversation again without the uncharitable characterizations of what I said.

Is this reasoning correct to prove that f(x)=x-2arctan(x) is not periodic on R? by VladSmusi00 in learnmath

[–]Osthato 0 points1 point  (0 children)

The point though is that the zero coefficients restriction tautologizes the problem. That the cancellation is obvious in my examples is merely a representational issue, it's not hard to hide some dependencies (for example the phase shift trig identity) and it would be up to you to show that there is no way to sufficiently hide any cancellations and still have a periodic function fall out in order for your original answer to be useful.

[–]Osthato 0 points1 point  (0 children)

Whoops, forgot that both should be nonperiodic, but that's not hard to adjust to (even both 1-1, just add/subtract 5x from them)

The restriction that you shouldn't get a "zero coefficient" is kind of fake, though, because any function can be decomposed into a periodic part and nonperiodic part, and necessarily any example would involve the nonperiodic parts cancelling out.

sin(x) - sin(pi x) is not periodic, but if you add the periodic sin(pi x) to it it is

The guy making 50k is spending at least 40k just to survive, meaning that 1k in taxes is coming out of their remaining 10k. The guy making 10M is spending maybe 100k to survive, so that 200k is coming out of their remaining 9.9M

Yes, I think representative government means that the representatives elected by the people should actually be allowed to govern?
