New Theories / Re: Is alzheimer a concequence or a cause ?

It's a consequence of a buildup of odd proteins in the brain.

And you know that the production of the proteins responsible of the death of the cells is not a mechanism used by the brain to delete unused cells ? Or you prefer to think that those proteins are the initial cause of the disease ?

While education can  often postpone the symptoms, it can't prevent them, so the analogy with losing muscle tone is not reliable.

How do you evaluate the effectivness of the "education" ?

People who keep exercising maintain muscle mass, but people who stay educated and informed still get Alzheimer's.

Probably because they think that they stay educated, but in fact the effectivness of the education was bad.

Its like people who try to train their brain using sudoku and other more sophisticated training sessions : The effectivness is almost null.
A brain with good fonctionning sensors (eyes, ears, touch etc) in a natural environment is perhaps what permit to the brain "to remain young".
Repeating the knowlegde you have acquired (the more you have, the more you can learn...because there is less change in the brain...) is not very efffective.

the chain in the video is acting with ferrofluid, not with water !

Thank you for the clarification, i was wondering about.

Conservation of energy is the reason why this device won't work in the first place.

Is the reason why this device wont work is not equal to this device is not working..
You dont have any device in front of you so you can only speak about theory, not about facts (thats how science work).

In the case of this device, that can't happen.

What "cant happen" ? That the potential energy is turned into kinetic energy ?
Of course, because this is not how this device is supposed to work.

The total amount of chain that is submerged would not change at any point of the rotation cycle: as much chain is being submerged below the water's surface at any given time as is being brought out at the same time. That means that the potential energy of the system is constant at all points in time. If the potential energy cannot be changed into kinetic energy, then the chain cannot move. So the device won't work.

I dont understand what you mean.

I only know that if i put more volume into water i got more buoyancy.
Thats what happen here : More length of the chain in water equal more buoyancy.
I dont think this part of the process is so difficult to understand.
Perhaps there is some countereaction elsewhere, but this point : "more force" is established.
If you dont understand, try again.

More difficult is :
If this is a hoax, where is the flaw ? Is there some new exotic phenomenon trying to maintain the amount of total energy ?
If this is not a hoax, where is the energy coming from ?

New Theories / Is alzheimer a concequence or a cause ?

« on: 21/09/2022 18:39:46 »

Many studies show that alzheimer is multifactorial.
So like cancer.

But there is no evidence that the symptom (called "Alzheimer") is external to the brain.
We can also suppose that alzheimer is the concequence of "the misuse of ones brain".

To be more explicit.
If you sleep all the day, so you dont use your musculature, it is obvious that your musculature will disapear during time.

Same with the brain abilities.
If someone cant change his mind, and this is what we can call "learning", it is also obvious that if someone dont use his brain usefully this will make the neurones of the brain disapear.
This can be viewed as some physiological adaptation contrary of the actual dogma that say it is some  disease.

Some evidence is that peoples with higher education are likely not to developp Alzheimer.

The benefits of getting a good education may go beyond landing a good job, and continue to pay off long after retirement. Evidence has shown that formal education, like high school and college, may reduce a person’s risk of developing Alzheimer’s.

Research published in 2020 by The Lancet Commission that examined dementia interventions found 7% of worldwide dementia cases could be prevented by increasing early-life education. The study found higher childhood education levels and higher lifelong educational attainment could reduce dementia risk. Exactly how education helps is a mystery, but researchers have several theories.

Never stop learning
The majority of dementia risk studies have examined the benefits of obtaining education early in life. But Okonkwo says some studies have shown that learning new skills and working in jobs that are cognitively complex in mid and late life could also help protect the brain. For example, a 2015 study co-authored by Okonkwo found middle-aged adults who worked in mentally demanding occupations — especially dynamic jobs requiring frequent interaction and socialization with people — had higher cognitive reserve.

Aquagenic urticaria is not an allergic immune response.

Aquagenic urticaria, also known as water urticaria and aquagenous urticaria, is an extremely rare form of physical urticaria. It is sometimes described as an allergy, although it is not a histamine releasing allergic reaction like other forms of urticaria; it is more a hypersensitivity to the ions found in non-distilled water. In affected persons, water on the skin causes hives to appear within 15 minutes and last for up to two hours.

1 : to move in or pass through the air with wings. 2 : to move through the air or before the wind eg Paper was flying in all directions. 3 : to float or cause to float, wave, or soar in the wind eg fly a kite, fly a flag.

Thats why I specified a "functionning" flying chicken.

Yes, it could be done. Let's not forget that evolution eventually transformed prokaryotic life into us, so evolution by artificial selection of chickens could definitely give you fully-flying chickens if you did it for long enough.

I have no time for that (starting from some unicellular to some flying chicken).
I mean in some mans life, perhaps in 30 years so around.

The traditional view of a male "rooster" is waking up the neighbourhood before dawn by loudly proclaiming has masculinity from the highest point in the area (eg the roof of the henhouse).
- Natural selection will promote the cock with the best flying skills...

Is there really natural selection at work in the farm or around the men waiting to eat them ?

But we can eventualy observe the Feral chicken, domesticated chicken who has returned to the wild.
Or observe the ancestor of the domecticated chicken, the Red Junglefowl,

Flight in these birds is almost purely confined to reaching their roosting areas at sunset in trees or any other high and relatively safe places free from ground predators, and for escape from immediate danger through the day.[24]

https://en.wikipedia.org/wiki/Red_junglefowl

They dont fly freely.
Natural selection dont give them further abilities to fly.

Thats why i was wondering if there could be some evolutionary barrier, too high, so the natural chicken could not go over the barrier in the natural environment, simply because of the limitation of the environment strain.
But perhaps if we could select them ourselve we could help them to produce functionnal wings (and other things that permlit such heavy birds to really fly, perhaps he would be less heavy etc.)

The evolutionary advantage would perhaps be enormous and we would  then have some flying chickens around the world like we have the pigeons.

New Theories / Re: This is definitely the first Perpetual motion

« on: 21/09/2022 12:58:47 »

It won't work because the force of buoyancy on the chain would be equal on both spots that are passing through the water's surface.

The force is not equal, because the length of the chain immersed in water, left (with water elevated) and right (water at normal height) is not equal.
You would be right if you used some floating objects, immersed at the place where the water is elevated and some other at the place where the water is not elevated.
You would effectively end up with the same force acting on the same type of object, because they would end up with the same equilibrium, independently of the fact that water is elevated or not... but you would however have some difference => potential energy of the object would be greater at the place where water is elevated.

But here we are not talking about the difference of potential energy of separated objects (because there is no equilibrium so there is no difference in potential energy when the objects are linked) but about the difference in term of force.
Instead of potential energy difference when objects are separated we have the production of some force when the objects are linked.
And the work of this force is easy to calculate : Because of the energy conservation principle, its value is equal to the potential energy difference when the objects are separated.

Physiology & Medicine / Re: Is there any way for the immune system to detect water molecules?

« on: 20/09/2022 22:37:32 »

Yes, the immune system reacts to the presence of water by working properly.

This do no answer the question :
Why cant immune system react to water ?

First : What is the immune system ?
We dont care.
Here we are only talking of some small portion of the immune system, the immunoglobulin.
These molecules are generic peptids having at some position of their structure some variable structure having the ability to recognize some other particular molecules.
Can they recognize water molecules ?
No.
Because first the water molecules is what permit the immunoglobuline to have some neutral inactivity.
The neutral state is : A immunoglobuline with some water around : Waiting to be activated.
With no water, nothing will happen.

Then, to "activate" the immunoglobulin you need to have some "antigen", some bigger molecule as water.
Some protein or some polysacharide per example.

Water is too smal to induce any "activation" and is part of the neutral waiting state of the immunoglobulin.
Thats all.

Unfortunately, you are not bright enough to recognise that "someone" is not the same as "everyone" (nor that "quelqu'un" and "tout le monde" are different).

Try to get focused;
Nobody talk about "someone" and "everyone", here the polemic involve "anyone" and "everyone".
translated :
Personne ne parle de "quelqu'un" et de "tout le monde", ici la polémique implique "tout le monde" et "tout le monde".
Retranslated :

Change "body" by "one" if your intellect dont permit you to understand the translation.

Sure, everyone know that chicken can "fly a little".
So it should be obvious for everyone who not think i am stupid, that it is not the question i asked.
At least because i am some biologist as you already know...

No, i mean fly for real, like any other flying bird.
The dukes, the craw, the parrot, the pigeon, the etc etc etc.
The majority of birds fly freely, capable of flying many kilometers.

But chikens, part of the galliforms do not really fly.

Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species are more colorful than the females, with often elaborate courtship behaviors that include strutting, fluffing of tail or head feathers, and vocal sounds. They are mainly nonmigratory. Several species have been domesticated during their long and extensive relationships with humans.

Physics, Astronomy & Cosmology / Re: Is there a medium for smell to travel through in space?

« on: 20/09/2022 21:42:05 »

Smell do not travel into space.

But molecules and atoms can travel into void space, and into "air" (void space filled with "air" molecules).

So when the molecules enter into someones nose, the molecules can interact with the cells present in the nose.
This interaction is changed into electric charges and the current flow to the brain using neural cells.
Into the brain, the change involved by this current is named "smell".
It is what you perceive, "the smell".
"Smell" is a perception.

The smell is the interpretation of the electric signal originated by the interaction of the nose cells and the "smelling" molecules, by the brain.

You are now trying to argue that you speak better English than two native English speakers- even though your writing is riddled with errors- because an electronic translator agrees with you- even though it disagrees with itself.

DeepL Translator is an IA using deep learning technology.
If you think it is defect, feel free to send the conceptor a mail to explain them that "you" the great bored chemist, have found some problem they have never seen before.
You would be very kind of course to inform us how loud they have laught when you have announced them your expertise.

How does DeepL work?
November 1, 2021

We are frequently asked how it is that DeepL Translator often works better than competing systems from major tech companies. There are several reasons for this. Like most translation systems, DeepL Translator translates texts using artificial neural networks. These networks are trained on many millions of translated texts. However, our researchers have been able to make many improvements to the overall neural network methodology, mainly in four areas.

Network architecture
It is well known that most publicly available translation systems are direct modifications of the Transformer architecture. Of course, the neural networks of DeepL also contain parts of this architecture, such as attention mechanisms. However, there are also significant differences in the topology of the networks that lead to an overall significant improvement in translation quality over the public research state of the art. We see these differences in network architecture quality clearly when we internally train and compare our architectures and the best known Transformer architectures on the same data.
Training data

Most of our direct competitors are major tech companies, which have a history of many years developing web crawlers. They therefore have a distinct advantage in the amount of training data available. We, on the other hand, place great emphasis on the targeted acquisition of special training data that helps our network to achieve higher translation quality. For this purpose, we have developed, among other things, special crawlers that automatically find translations on the internet and assess their quality.

Training methodology
In public research, training networks are usually trained using the “supervised learning” method. The network is shown different examples over and over again. The network repeatedly compares its own translations with the translations from the training data. If there are discrepancies, the weights of the network are adjusted accordingly. We also use other techniques from other areas of machine learning when training the neural networks. This also allows us to achieve significant improvements.

Network size
Meanwhile, we (like our largest competitors) train translation networks with many billions of parameters. These networks are so large that they can only be trained in a distributed fashion on very large dedicated compute clusters. However, in our research we attach great importance to the fact that the parameters of the network are used very efficiently. This is how we have managed to achieve a similar translation quality even with our smaller and faster networks. We can therefore also offer very high translation quality to users of our free service.

Of course, we are always on the lookout for very good mathematicians and computer scientists who would like to help drive development, further improve DeepL Translator, and break down language barriers around the world. If you also have experience with mathematics and neural network training, and if it fulfills you to work on a product that is used worldwide for free, then please apply to DeepL!

Very interesting.

I dont understand the part with the ferrofluid but the principe with the capilarity mixed with archimedes looks obvious as soon as you have understand it.
The guy dont explain it clearly (even if i speak german fluently) so i will do it here :
You use some device to elevate the water using capilarity.
You put a floating thing into this elevated water.
You let the floating thing fall after it has elevated above the flat surface of the water (because of the elevation added by the capilarity), into the part of the flat surface of the same water -but not elevated- using some circular chain of those things.

The device he presented in his video seem to be functional and at very first glance could be right in a physical point of view.

So, 2 possibilities.
1. He is a crook.
2. It works.

Everyone can test his invention and verify if 1 or 2, so thats at least the good point.
