The point is that in order to draw a continuous line your pen must pass through irrational points to get from one rational to the next. Equally for (physics) fields to follow the equations of physics, the field lines must pass through irrational points to get from one rational point to another and in order to make a completely closed line or shell or surface or whatever a the closure must block the flux from escaping through irrational points on that closure.2 points

There are several acids: tartaric, citric, malic and maybe more. Tartaric and malic are dibasic and citric is tribasic. Each carboxylate group will have a different tendency to release H+ (different pKa). All are contributing to the overall H+ concentration. To make matters worse, you can get (as a winemaker you may indeed want) malolactic fermentation, which converts some of the malic acid into lactic acid, which is monobasic, with a fairly low pKa. I imagine the mouth feel and perceived acidity of the wine may depend on how much of each is present. Since saliva is slightly basic, you could perhaps get a sort of buffering situation in your mouth. Quite complicated, I would think.1 point

I assume the idea of titration is to determine the amount of acid present rather than just the pH. As there are several weak acids present in wine, the pH will tell you the concentration of H+, but that won't tell you how much of the acid molecules there are, since they are only partially dissociated and if there are several you won't be able to correlate an H+ concentration with the total amount of all of them. But I'm guessing a bit.1 point

Does the fact that set of real numbers is uncountable, as opposed to rational numbers, for example, play any role anywhere in physics? More generally, do infinite cardinal numbers play any role anywhere in physics? For example, in an infinite dimensional Hilbert space, does it make a difference if the number of dimensions is countable or uncountable?1 point

What I find fascinating is that the tactics of creating these alternate realities is straight up from Goebbel's strategy book. And this includes terms and tactics like isolating folks from "mainstream media (Luegenpresse)", rile against social Marxism (whatever that is) and so on. There is barely a change in wording. It is so weird that with all the knowledge of our past, we collectively forget things just like that.1 point

I don't know why, but this saying came up in my mind: "Poise is the art of raising the eyebrows and not the roof."1 point

I think the question could be translated into: Is there any way in physics that we can (experimentally meaningfully) ask the question of whether space/time, or either one of them --or any other variables for that matter-- has the power of the continuum? I don't think there's been any proposal to test that, and I don't think there can be. It is a very interesting question, though. When you report an experiment, you always do it by means of a finite string of numbers and/or characters. I think this says it all. It's probably an undecidable question, unless some connection is established --that we don't know of as yet-- between discrete mathematics and transcendent mathematics. It doesn't seem feasible that that will happen any time soon. Plus, I also said somewhere before, Self-quotation from:1 point

Thanks! That's super cool (cheap pun). I've known about this place for a long time, but have never been inside.1 point

I think it doesn't. I think any measurement will fall short of that precision. And at the Planck level, it may not be possible even in principle? You may get 0.3333333329 with some error margin. Rational numbers may only lie in some Platonic realm. (similar idea is that all surfaces in the real world are not precise 2D, but some fractal expression, like around 2.11112 D) Same thing for irrational numbers. And plus 1, cool thread.1 point

Agree Just expressing my limited amount of knowledge on the subject. Need some time to try and formalize this, have problems with this endeavor. I admit defeat. It being I have no idea how to formally explain it. It being my idea/discovery. Mathematics is the structuring of the universe, ergo nature, into a set of discoverable rules and formulations. These formulations are conceived by the human mind. A set is itself an inverse of reality due to those languages which better describe reality. Languages, of the romantic kind, describe humans endeavor to discern between the reality and fictitious efforts of noise. That's probably the best way I can put my discovery. I think I am trying to describe automata theory. Not sure though. Please help.1 point

I would certainly try that. It never ceases to amaze me how many extraneous ingredients manufacturers seem to need to add to ready meals. Also you can cook the onions slowly which may help. I don't seem to be bothered by oligosaccharides myself, so can't advise from experience. But I do have quite a lot of garlic, brassica vegetables and lentils in my diet so, looking at @StringJunky's explanation, it may be that I have reached equilibrium in my gut long ago and that's why.1 point

People went looking for that frame with special properties and they couldn’t find it. We are not moving with respect to it nor are we at rest in it. The experimental evidence is that it doesn’t exist. The extraordinary thing here is the idea that one can make a claim that there’s a preferred frame but retreat at any request for evidence in support of the claim.1 point

Thanks! Anyway I am still using firefox. Another question is window 10 also keep your search records in search bar, and you have to delete them one by one, not delete all of them by one click. I am not surprise that The West is falling, it is just so dumb, example every website ask you do you accept "cookies" or not? lol, the rule must be made by those politicians know nothing about IT And those dumb webmasters use three frames, and give you 2 inches space to view their web pages.-1 points

From the experiments of particle colliders..a jet of particles are released as energy is transformed to mass... according to model represented by the diagram there is redefinition of energy and mass so that....the particles are always there and energy has to cause tearing for the particles to be released in a manner consistent with Energy being equal to mass multiplied by speed of light squared(Einstein's formular) Energy is continuously produced at emptiness consciouness boundary...which is detected as dark energy powering continued expansion of the universe as it elvoves.-1 points

.....jet of particles after tearing of Higgs fields(mass) after an equal amount of energy has been applied during particles collision...this is possible as shown in the elementary structure below... in this case as shown in the diagram above particles gain mass when Higgs field interact with spacetime fabric,,the diagram is a 2D representation of otherwise what is spherical bubble like structure,the Higgs fields emanate from photon surface as virtual particle are emitted. at neutrino surface the fields are weakly forming thus forming "primordial Higgs fields",hence the small mass of neutrino. As shown in the structure this fields protrude from the surface of of elementary particles interacting with spacetime fabric therefore it generates mass by dragging it generating resistance to movement that appear as mass. The protrusion is minimum at neutrino and increases up the hierarchy up to Higg boson. How those boundary,levels,surface develops is shown as illustrated in the following diagram-1 points

Let me not beat the bushes,to me this diagram is excellent...maybe it's just on my head...I had to read Qm,BB,GR for several years for me to come up with this ...bt time will tell if such ideas will help someone somewhere to come up with... ideas that will help the rest of us.....if a mad person goes to the doctor....the doctor will try to diagonise symptom and try to understand the spectrum of mental illness....what about if the doctor just shout to the patient you have a demon in you!...where could progress come from in the society. In this model photon emits inverse planck's number of stable virtual particles per second that is the beginning of quantization....below this threshold it become dark photon. Virtual particles get highly entangled with it's source therefore virtual particle emitted from photon are highly entangled to it. Virtual particles emitted from particles with crests and troughs get entangled to those crest and trough to form charge....the arrows... Virtual particles dimension is similar to photons surface dimension....therefore they both move at the speed of light in spacetime fabric. Virtual particles entanglement near their source creates constraints... reducing their degree of freedom as they move up the hierarchy...this constraint give rise to Higgs field. Oscillation between highest degree of freedom and lowest degree of freedom give rise to wave nature of Higgs field. In Sea quark there are infinite oscillations in their Higgs field degree of freedom in this case I will call them vibration but collapses to three crests and three troughs that give rise to valency down quark Gravitation influence take place at virtual particle level....this involves entanglement of of virtual particles...in this case entanglement involves exchange of information....this explain why gravity is the weakest force(takes place at virtual particles level)...and it's involved both in dark matter and normal because both emit vitual particles....the constant rate of information exchange between virtual particle is given by Newton gravitational constant G.... Mass and gravity are United at Higgs fields when this fields become saturated emitting temporary graviton that decays at to less than planck's time to gravitation waves... Gravitation waves become the template of spacetime curvature...when it interact with other virtual particles making spacetime fabric....-1 points

I have a question, born of necessity : I believe that simplicity should always be at the center of everything : complexity becomes a poison for intuition and truth, when it is a mental masturbation apt to feed the ego of scientists who do not seek universal truths, but elitist beliefs to feel superior regardless( or, simply, the need to feel important, which in itself is an understandable need, but not at the cost of truth and justice ); the ego must not be developed without putting truth, courage, justice, the critical and rebellious spirit, as its foundation; otherwise it will be moved by the need to lie, to omit, to adapt reality to his oasis of certainties that have never really been questioned (in their foundations), preferring the illusion of having done so, made possible precisely by the use of complexity and dogma passed off as science; complexity, yes, but when it is really necessary, without ever losing sight of simplicity; but perhaps, since complexity is also, from a certain point of view, relative to the ability to know how to handle it, then it is better to say that simplicity is that something you can most easily relate to those things that communicate universally, practically all the time, while complexity is something that moves away from that, but still DERIVES from that, from simplicity, and is not something disjointed from it. From simplicity to complexity, via modularity, which is still a way of managing with the measure of simplicity, complexity I am a firm believer in the following statement, "You haven't really understood something until you are able to explain it to a five-year-old" ( or "You haven't really understood something until you are able to explain it to your grandmother." : in this statement there is a universal truth that should, must, permeate everything; what strays from this assertion, strays from truth, and therefore, from justice. --- Here --- Here we get into the specifics, with the five Ws ( https://en.wikipedia.org/wiki/Five_Ws ), on those units of measurement. --- Here However, the definition of ampere seems to me to be more of a derived quantity/units of measure than a fundamental quantity/units of measure; And in fact here https://en.wikipedia.org/wiki/2019_redefinition_of_the_SI_base_units it is stated that the new definition of 2019 is more 'fundamental', than the previous one ( although it is also said that "A consequence of the revised definition is that the ampere no longer depends on the definitions of the kilogram and the metre; it does, however, still depend on the definition of the second." ) and so on. --- Here "have been chosen" Are there actually only seven, of these physical quantities/units of measure, or is there an arbitrary choice, and would there also be more, perhaps not considered for certain, or indeterminate, reasons ? --- Now, on this premise, I ask you : is there a searchable source for study where the whole ( or almost ) physics is ALL expressed in terms of only fundamental quantities/units of measure, thus without the use of derived quantities/units of measure ? Derived quantities/units of measure have their utility, certainly; but My request is also an epistemological and gnoseological experiment; to always express everything, whenever possible ( is it always possible ? ), in terms of only fundamental quantities/units of measure, I feel this as a security on the side of truth, thus of knowledge that is going to expand with research; and where it might seem that it is not possible to apply such a principle, it must be shown why, with empirical experiments attesting that something more must be added, of 'only' fundamental quantities, in order to be able to continue with research; essentially, simplicity is thus the guarantee of not ending up in blind alleys without realizing it, dazzled by unnecessary complexity. Fundamental quantities/units of measure are a function of what ? Of our senses; the measuring instruments built by the Human Being, flow from the awareness one has, of one's senses ( and I mean these : https://www.hellahealth.com/blog/wellness/humans-five-senses/ , https://bigthink.com/surprising-science/think-you-have-only-5-senses-its-actually-a-lot-more-than-that/ , and many more ). It might seem a limitation, but the Human Being is meter and measure for the whole of creation, someone would say ( and I agree ) Thank you.-1 points
