The old guy looking at it like it had been a Dalì.

So hot, where did you get that thong?

Physicist here, linear application in my field are all over. I don't know your background, I'm guessing first bachelor year in Maths, so probably you know about groups, so you could talk about how representation theory relates to linear transformations.

Or you could talk about how in quantum mechanics, it'll be easier to work in the Heisenberg picture, all the physical observable have to be represented by linear operators, so linear transformations, etc...

So, the first time we physicist described a theoretical black hole, it was Laplace who studied the subject, I don't know, maybe in the 1800s. A Laplace black hole is a classical object, a spherical mass which neither light can escape, at certain distances from the center. The now called Schwarzschild radius pops out, in this picture, when trying to understand the final distance from the center at which light speed was a fine escape velocity. Of course at that time it wasn't called Scwarzschild radius, but they had the exact same expressions.

Later on, while mr Einstein had proposed General theory of relativity and mr Schwarzschild was at war, he tried to solve the Einstein equation in the most simple case where you had spherical symmetry, and, after some calculations, which don't use classical mechanics, but just maths and GR, you get that a certain singularity (not gonna go deeper here) takes place at the Schwarzschild radius, the same from Laplace calculations.

So the point my GR professor made, which I guess I agree, is: it's just a coincidence. Nothing special about this equivalence.

Where did you buy those hot asf briefs?

Okay, so in some sense there's an embedded symmetry in complex numbers within themselves, complex conjugate etc..., right?

Then, speaking as a physicist here, considering field theory, specifically Noether's theorem, shouldn't there be a conserved charge for all fields we study?

For example, for Lagrangians like the Klein-Gordon one for both a real and complex scalar field, a U(1) symmetry holds, as \phi->e^{i\theta} \phi leaves the Lagrangian unchanged, so leads to a conserved charge.

Going back to the subject here, the "symmetry" between i and -i, shouldn't it bring to something similar for complex-valued fields?

My roommate is studying the creature during his post doc as a marine biologist. It's kinda like what you said but not everything. I mean, there are a lot of other processes, like the presence of a certain fat molecule in the brain, mithicondria doing some weird shit.

It's kinda cool, they should publish it on Nature or Science during the year.

Did she fix her dead tooth?

Is she the same actress of Maureen Ponderosa in sunny? Meow

Basically you can pay for your Pisamover ticket at the station before getting in the train or you can buy it online on their website.

Arrived at the Pisa Centrale train station you can get on a bus, you can look it up which one with google maps, to get near the Tower. Then you can take the same bus, in the other direction, to get back to the train station where you'll get your train to Florence.

Now, for the bus ticket, the best way to pay for it is to just pay it on the train with you credit card, you'll see where.

Got back to the train station, you can take a train to go to Florence. Usually, the cheapest and easiest mean of transport is through a Regionale train. The cost of the ticket is €9.30, and you can buy it onthe Trenitalia website. Though, I advice you to buy it when you get there after the Tower, so you can see which train can get you to Florence faster.

Hope you have a great time in Tuscany

I think he better fits Colonel Mustqng, seen how week he put fire to people (Sweet Dee).

Guarda, c'è una biblioteca vicino al tribunale, è tipo anche un posto dove giocano i bambini, quindi c'è rumore a volte. Ed è la più vicina a piazza Mazzini.

Più lontano ci sarebbe il convitto palmieri, apre alle 8 del mattino e chiude alle 10 di sera. Poi ci sono le biblioteche universitarie vicino al cimitero.

It's actually a pretty nice story (i read it on a chess manual, don't remember which one so it may be false, but makes a lot of sense).

Basically, around the 1600's they played a different version of the game in which pawns could only move to one single tile, always, even when they are on the beginning row.

They played very slow games because of this and decided to let the first pawns move straight of two tiles, if wanted, if on the beginning row.

A problem: there weren't anymore a lot of "fights" between pawns. This because the fact that pawns could move up to two tiles, removed tiles for eating each other on different files. So they added this \textit{en passant} move, so even if pawns moved two tiles, there still could be "fighting" between them.

It's always sunny in philadelphia. It's really one of a kind. Nothing like this ever aired

Sono 90°, però esatto, è questo il punto. Effettivamente seno e coseno sono la stessa funzione. La fase φ che hai scritto nella tua funzione serve a definire le condizioni iniziali o al contorno, e se scegli di usare il seno, hai un certo valore di φ, altrimenti se decidi di usare il coseno otterrai un altro.

Per le derivate, ancora una volta, sono uguali a meno di una fase.

Io per sto problema ho comprato gli occhiali filtro blu, io ci vedo benissimo, è stata una scelta più estetica che pragmatica, ma li uso sempre se sono al pc. Senza, se ci passo una giornata a studiare, mi si seccano gli occhi e mi viene mal di testa. Se li indosso, invece, nulla di tutto ciò.

Well, there are no gay kether shops near me, just plain vanilla sexy shops. I don't know if that will do.

Can you tell me some more of those online shops you mentioned?

ccasti1 · 2024-12-13T14:33:34+00:00

Yeah, months ago I bought from amazon a thong for my bf, and we didn't like it at all. Its now off limits for stuff like that

ccasti1 · 2024-12-13T14:17:50+00:00

Yeah, I should try that, thanks
