Math is not based on reality, it is not a science in fact.
Chemistry has a lot of rules and exceptions to those rules.
This is because most of the knowledge in chemistry is empirical, thus you get theories that work for some molecules and not with others.
This is done to simplify the knowledge.
You could for example treat everything through the quantum physics theory, which works quite well all around; however that is extremely complicated and requires a bunch of time and calculations.
Thus we use simpler theories that do not generalise so well but work in specific applications so that will make it easier for a person to predict what's going to happen.

Then again, a lot of research in chemistry is basically "let's try synthesizing this molecule in a bunch of different ways to see which one works best and then hope that it is actually useful"

The smallest thing chemists are concerned of are electrons.
Electrons however are very important in chemistry: whatever you're doing you have to consider what electrons are going to do since that is what determines the outcome of a chemical reaction.

I hope nobody is going to actually use this recipe to make meth.
Information is there and you could actually do it, but a lot of different things can happen you should be aware of.
It is not a game and you might very easily injure yourself during the production process or by producing some impure stuff which you're then going to consume.

If you really want to make methamphetamine look online, there is a bunch of serious recipes that will explain the process in a detailed way; it's quite easy and it can be accomplished by non chemists, but you should be aware of the dangers *before* starting.
Moreover, I would advise against using a microwave to heat up the solution: heating a glass container while constantly stirring the liquid will provide a much better heat distribution and you won't get heat pockets that might produce side products.

#tasse #residenza #spagna
Mi sto trasferendo in Spagna e porterò qui la mia residenza.
Ho visto che la residenza fiscale viene trasferita dopo 183 giorno che vivo qui.
Sapete se questo vuol dire che quest'anno dovrò pagare metà delle tasse in Italia e metà in Spagna oppure che a settembre 2023 quando dovrò fare la dichiarazione dei redditi sarò già considerato residente in Spagna e quindi pagherò tutto in Spagna?

In più ho delle azioni e vorrei sapere se c'è qualcosa da fare per trasferirle alla tassazione spagnola o se basterà poi dichiararle quando dovrò pagare le tasse.
Grazie

#email #mutt #neomutt #mbsync #linux
I'm using neomutt to manage my emails since a few years.
I sync with my mailbox through mbsync running it every few minutes with a cron job.
The only annoying thing is that when I make some local changes these are not immediately propagated to the server but I have to wait for the next call of the cron job.
This is annoying if I move or delete some mails and switch off my computer immediately after because I will then have my local mailbox out of sync with the server.
Do you know a way to sync local changes with the server as soon as I perform them?
I'd like deleted mails to be marked as deleted on the server as soon as I delete them in mutt rather than waiting for the next mbsync activation.

Thank you very much.

Too large memory sticks sometimes are not properly read by the bios and cannot be used to install an operating system.
Try with a 4G usb drive.

Ti consiglio di esercitarti a calmarti allora.
Prendermi uno schiaffo per un motivo così futile mi farebbe adirare parecchio.

Are you talking to me?

Nel nord Europa da qualche anno si sta cominciando a recuperare il fosforo dalle acque degli scarichi. In questo modo si riutilizza il fosforo riducendo la quantità che deve essere minata. L'estrazione di fosforo è un processo molto inquinante e produce scarti inutilizzabili che rendono sterili i terreni dove vengono gettati. Inoltre questo ha il vantaggio di ridurre la manutenzione degli impianti di purificazione in quanto diminuisce la quantità di sedimenti e dunque vanno puliti meno spesso.
Il fosforo viene ottenuto in una forma già adatta a fertilizzare i campi, tuttavia non essendo idrosolubile rilascia i nutrienti nel terreno molto lentamente.
