First Incompleteness Theorem: “Any consistent formal system F within which a certain amount of elementary arithmetic can be carried out is incomplete; i.e. there are statements of the language of F which can neither be proved nor disproved in F.” (Raatikainen 2020)

These are 50 cm wide half spheres. If you find that comparable to the situation in the picture your appetite must be enormous.

I sadly don’t understand these units and your point is drained in it. The point I want to make is that the “force” of vacuum is limited by the difference of pressures.

You say it changes “drasticly” with area or suction but that is untrue. It changes linearly with area (not drastically) and pressure difference has a maximum. The maximum is defined by the pressure of the vacuum(=0) and the pressure of the ambient air (1 arm). Both are constant so the maximum is constant and actually not that big.

The difference between ambient pressure and inner pressure is always smaller than ambient pressure. Delta p is therefore limited. The force comes from Delta p times contact area which is constant.

I sadly don’t know your units of mass but as I said a perfect vacuum over an area such as the Bowl is as strong as a muscle. The Ravioli will in no world produce a strong vacuum so muscle will win in most cases.

It’s delta p and not fraction p. The difference between ambient pressure and inner pressure (at least zero) is always smaller than ambient pressure. Delta p is therefore limited.

The pressure acts over the area of contact. For a perfect vacuum it would lead to ~1kN of force. This is the same order of magnitude our muscles produce. If you take into account that the vacuum results from cooling over such a small temperature interval the force can’t be too high.

The power of suction is physically limited. That means it either isn’t suction or op is crazy weak. My guess is that the plastic melted (probably not from boiling Temp) or op is strongly exaggerating.

The normal lead we know but still special. Is the last stable element in the PSE and there is the theory that it’s actually radioactive (unstable) but the decay is so slow that we probably never see a single atom of it decaying.

Yes. Every now and then we get a paper claiming that they found a HTSC. It always is a big deal because they are considered the holy grail of solid state physics. Later we find that it’s a mistake.

We are pretty good though. Records are in the area of −135 °C (138K, -211°F) but the phenomenon was thought to be at a few Kelvin max in the last century.

The big BUT is that it’s science. Meaning that it is not granted that such a material (superconducting at ambient temperature and pressure) even exists

I would say “High Temperatur Superconductor”. If they can be made cheaply, they solve our Energy Problems in almost every way. Turbines will become more effective, Transport of Energy cheap and lossless and storage crazy effective. They will also revolitionize meassurement of magnetic fields witch will have a huge impact on medicin and other fields.

Cant you get chicken cooked in it’s own blood in Portugal? Why ist this your favourite?

Not if you are a toddler. Are you a toddler?

Correct but if the effects are severe we could already say that it’s bad. If they are harmful the effect of currently normal levels is on the milde side.

The toxicity of micro plastics is very minor. To get to the point where it is a problem you need to be exposed to it for a very long time.

I think our asbestos is halogenated organic chemicals like PFAS. They are toxic in every way and we are addicted to their use in food chemistry. Not to eat or anything but to make the packaging look nice.

Because they are indestructible by any natural way their dose in the water supply is ever rising. The cost of health issues is already in the hundred billions.

Micro plastics might be a problem for our children when the dosage in clean water gets to extreme levels.

This question is as American as it gets. No mention that it has no interest to everybody that is not from the US. The topic is about unhealthy food that is made almost similar in an anti human economy that only cares for price reduction. It’s also very Reddit.

In similarity to coffee: Consider very small producers. The problem with coffe and chocolate is that the real taste only results from the last production steps (after fermentation and roasting). That means that companies that buy from many small farms (sometimes hundreds) have no clue which farm did it the best and thus the farmers also don’t know it.

But because only the farmers have a really strong influence on the quality of the chocolate they need to know if what they did was right.

Now a small company might have their own farms or work with very few suppliers they can give feedback about the quality. The farmers can produce better raw chocolate beans and the chocolate tastes best.

Also because the farmers learn their worth we westeners can’t exploit them so nicely and we avoid slavery.
