Are there any advantages of being bilingual beside being able to communicate with more people? Most anglo-countries are monolingual, and they are doing quite well.

People from Switzerland and Luxembourg are usally trilingual, and they have the highest HDI in the world. However, you can probably find many examples that prove the exact opposite also. People in India usually speak many language, but it doesn't seem to be of any advantages to them. The examples I gave are extremely binary, and there are other variables to take into account of course.

I think that is debateable and difficult to ascertain. You could argue that the education back then was probably more rigorous, but they didn't really have the life circumstances to shine. My dad was pretty smart, but he went into the military rather than into further education and eventually got commissioned as an officer, but he left and was basically a criminal until his death (selling illegal things). I reckon he probably killed a few people as well.

>I think that is debateable and difficult to ascertain. You could argue that the education back then was probably more rigorous
Same thing for my case. My father is monolingual, but he took an university education. The education was much more strict and rigorous back in the days, and it was mostly focused on being "difficult". Not difficult in the positive way, but they needed to memorize a lot, and you were not able to use aids or sheets during exam. People mostly memorized stuff instead of actually focusing on understanding and implementation.

I entirely agree with this. I believe that I have a completely different view of the English than an Anglo monolingual speaker. The con is that I sometimes struggle to find the right words in my native language.

Well, either we prevent the negative effects of smoking in the first place by basically turning it into pure nicotine (the problems usually come from the tar in the cigarette and the carbon monoxide from it not being burned completely) but nicotine itself has negative effects like addiction and heart problems, and removing everything else would basically change the 'taste' of the cigarette. Or, you could prevent the effects by some sort of lung enhancement which prevents the chemicals from the smoke from accumulating in the alveoli, perhaps a filter of some sort, but that wouldn't help with the carbon monoxide and nicotine issue,

>discussing economics in any way that doesn't present "fallacies"
The economic system we employ can be looked at as an antidote to the glaring problems that have arisen from the past model.
Any economic you employ will inevitably have problems because humans want paradoxical things as whole, and because humans change/evolve, whatever you want to call it.

It's more like what do we need to put on the stage now for the sake of generative movement and development
In culture right now, we're going a bit more bottom up than top down. This will likely continue for some time, I'm just presenting an economic system that works in accordance.

No model is without flaws because it's a distribution of human energy and finite resources, and economic structures are put in place around the values of the people, which always change.

If one burns ethanol in an indoor fireplace, how much oxygen does get used, or even better; how much volume of air is depleted (at like 24°C) oxygen-wise per litre (or 100ml) of burned ethanol?

You would break entanglement by doing that.

Example:
Two photons with opposite spins are created like in my post. They are entangled so if you know the spin of one you can deduce the other. If you take one photon and run it through a polarized filter, it is no longer entangled with the other photon. It is now entangled with the filter, and you can deduce it's spin based on the properties of the filter. You can no longer say the spin of the other photon is the opposite of the polarized filter photon.

FTL communication? not quite. when you measure your photon, you have no idea whether it has already collapsed or whether you were the one who caused it to collapse. there's no non-destructive way to observe whether or not an entangled particle has been observed already. that's the reason that information can't be conveyed this way.

How do you calculate the work done by an ideal gas when pressure is dependent on both the volume and temperature of the gas? I've looked through Wikipedia and Fundamentals of Physics, but both of them gave formulas for work when at least one of the variables in pV = nRT was constant.

There are a variety of relationships between volume and pressure for a given total work done depending on the application.

In practice, to find the relationship between pressure and volume at each temp is no more or less experimentally difficult than just measuring the work done directly. So given that you want the total work done, just measure it.
If it is for a project that is too huge to do experimentally, your best bet is >>12272114 for the closest configuration.

Nothing in the real world is adiabatic or polytropic and both still require you to know n.

There's plenty.
Einstein wouldn't accept the results of what is now known as quantum entanglement, saying somethingalong the lines of "are we to expect t o particles can have a 'spooky action at a distance'?" (The term, which was originally dismissive, is now how popsci documentaries call the phenomenon).
There are other ideas which are quite debatable about our interpretation of some results. The idea that the universe is expanding, or that there ought to be some 'dark matter' causing our calculations to differ from observed data are a couple questionable ideas in current physics.

Publishing in the prestigious journals is impossible without political connections and when prizes are awarded for work that was done by many people, the one who gets the money is usually chosen politically. Usually even getting into a position where you might generate a result deserving of being in a great journal means you already made those political connections. However, it's just the same political bullshit about who gets post docs and professorships.

When I was doing my PhD at Georgia Tech, in my first year the faculty was about 100% white men. There was a Brazilian and a couple of Chinese, one of which was a woman. The faulty that got hired during my four years there were two women, a Thai, two latins, and one white man. I don't think the statistics that had led to the ~100% white man faculty suddenly changed so that 2008-2011 all the best qualified applicants had superficial appearance statistics which suddenly diverged from the previous trend. The same thing that got those women hired is what controls who gets to publish in the great journals and who gets the good post docs.
