@0celouvsky there is no suspend button. If the post gets enough valid flags, it gets squishes and sometimes triggers builtin suspends. (In this case, the post out of context while I was looking at it on the flags list, I accidentally hit the "Valid" button, stupid phone, so it triggered a suspend and delete. Whoops.)

@0celouvsky @0celouvsky does "accidental misclick on the buttons" answer the question?

0celouvsky

@ThomasWard Clicking flag is basically a surefire suspend button.

@0celouvsky (I didn't click flag, I was reading the active flags list. Mistakes happen, it's why you're not suspended)

Rail transport in Brazil

Rail transport in Brazil began in the 19th century and there were many different railway companies. The railways were nationalised under RFFSA (Rede Ferroviária Federal, Sociedade Anônima) in 1957. Between 1999 and 2007, RFFSA was broken up and services are now operated by a variety of private and public operators, including América Latina Logística, Companhia Paulista de Trens Metropolitanos and SuperVia. == Track gauge == The rail system in Brazil operates on four rail gauges: Broad gauge: 4,932 km 1,600 mm (5 ft 3 in) gauge Metre gauge: 23,773 km 1,000 mm (3 ft 3 3⁄8 in) gauge Dual gauge: 396...

@BernardoMeurer "Although Brazil has one of the largest rail network, it lacks passenger transportation. Passenger trains were controlled by state-run companies until a mass privatisation occurred in 1996-1999, by then most tracks and rolling stock were in a very poor condition and most trains would not run over 60 Km/h even on broad gauge, forcing the now private-run railway companies to shut down almost every single regional and long-distance services in the entire country in the next 5 years."

Bernardo Meurer

Eh, okay, go back to the 50's. Brazil is a democracy again, after some (30?) years of a widely accepted as good or very good dictatorship (Getúlio Vargas was the guy). A little after that we elect this joker called Juscelino Kubitschek. His plan was called "50 years in 5" (Ciquenta anos em Cinco), and was basically to do a speedrun of making a proper capitalist country. One of his main points was to bring the large international car manufacturers into Brazil. (Continued)

So he did so, Ford, GM, etc, all came, mostly through Brazil-USA deals, and Kubitschek did his part and built roads fucking everywhere

Really, highways everywhere

Ok the reason is basically a crazy guy who ruled Brazil a few years back

Bernardo Meurer

4:52 PM

That was, even at the time, regarded as a bad strategy since Brazil's geography and aggressive flora didn't do well for the asphalt roads, and even the concrete ones were high maintenance. But, since he was lobbied by the US, Kubitschek held onto his plan and introduced cars in mass into the country, creating a car culture on the population

With that the trains got pushed back to industrial applications, where trucks didn't work, like transporting lots of very heavy materials, and wheeled vehicles took over all the other transport necessities

And that's basically why

Because some asshole took money to make the country be ran by cars

do u mean like $\sqrt{\nabla}$

Anonymous

@BernardoMeurer Yeah, teach me...I find most girls quite boring =P

0celouvsky

@Slereah for instance

I think that's just $p(x,\xi)=\sqrt{-i\xi}$

that's not very well behaved, is it

Slereah

it's alright

it pops up in QFT

ACuriousMind

I don't think I've ever seen it :P

Slereah

since it's the operator associated with $p$

@ACuriousMind It's in the schrodinger wavefunctional formalism

0celouvsky

5:15 PM

One takes $p$ from a so-called "symbol class" that has nice regularity and growth conditions

ACuriousMind

@Slereah Ah, yes, that would explain why I've never seen it

Slereah

$$\Psi_0[t, \Phi(\vec{x})] \propto e^{-\frac{1}{2\hbar c}\int d^3x\Phi(\vec{x}) \sqrt{-\nabla^2} \Phi(\vec{x})} e^{-\frac{i}{\hbar}E_0t}$$

0celouvsky

One also takes $p(x,\xi)$ to have compact support in $x$

So it's a bit limiting for $\Bbb R^n$ applications

it was made for compact manifolds

@Slereah Oh, $\sqrt{-\Delta}$ has a Fourier meaning

you don't need $\psi$do's, although those generalize the Fourier stuff

ACuriousMind

@Slereah $\sqrt{-\nabla^2}$ is pretty different from $\sqrt{\nabla}$ :P

@Slereah You can have $\sqrt{-\Delta}$ acting on $H^{1/2}$
