I am fond of saying that shadows are non physical, but they are very real. Well flying rugs etc is in the same class as pink unicorns at the bottom of my garden, in my opinion. But I can offer a mathematical proof that the 'indian rope trick' is a possible metastable state of certain compund pendulums.

I did note in my post about Monty Hall that the exact wording of the question makes a significant difference to the answer. My example makes this easier to see because we are not present to witness what the game show host says.

Yet again I dont know why my submit did not take. I wrote this hours ago. Getting back on to the topic of AI development, Are you aware that all so called AIs are programs implemented on present day computers or arrays of computers. Despite constructional or configurational differences all present day computers are still Turing - Church machines. That is their defining program can be implemented (in enough time) on the simplest possible turing machine. And that the output of such a machine is entirely predictable. Should we call an entirely predictable machine, that can allegedly think for itself, in any way intelligent / Or just a better, more advanced program ?

If only electrons could capture neutrinos as those posted pages show, we wouldn't need the neutrino detectors we currently employ. I notice that these pages mention several times that the electron as a cube is a model. I can't find anywhere they say the electron is a cube. However I also can't find anywhere where they distinguish between free electrons and bound electrons or expound the Pauli principle.

Let's throw in a few facts and figures shall we ? The population density is around 98 persons per square mile. That of Germany is around 625 persons per square mile. Eise comes from an area of even more densely populated. This has two results. 1) Germany has far less scope for the spread out american housing estates we see in the movies. 2) Germany is also pushed for food production space. The first time I visited our friends in North West Germany I was struck by their typical house construction, which always included a huge basement. My friends explained that since we had flattened the industrial heartland of Germany in the war everything was new (unlike France or England). And the new building regulations required a bomb shelter basement for all new houses.

One important thing to take away from this discussion that I have yet to mention is the enormous difference between interpolation and extrapolation. Interpolation is a fancy word for 'bracketing' the hypothesis between known phenomena or values. Normally it is only us mathematicians that look for 'pathogenic counter examples'. Nature, by and large is pretty amenable to interpolation. Of course you have to make the barakets wide enough to cover many eventualities. Hypotheses such as the big bang, Everett's universal quantum function, and many many others especially in cosmology are not only extrapolations but very very large extrapolations. Extrapolation is by its own characterisitc open ended. And the further you get from the known the more wildly out your hypothesis can easily be.

I think I understand the sentiment about the ocean and I agree. Brunel was a far better ship designer than Kaiser, because he had that innate 'feeling' or empathy for his subject, but also for the scientific method. However modern science (it is not confined to the West) has found out more about the ocean than all the religions of the world put together. As for AI building, consciousness and intelligence are different abilities and both exist on a scale, neither are just on or off. Yes I agree with exchemist that if all the universe was just one large consciousness then there would be nothing for it to experience.

So long as you read it critically. Remember the old saying. If an expert is someone who knows a lot about a little Then a true expert is someone who knows everything about nothing. Sums up my suspicion of 'everything theories'. 😀

In this day and age professional people are required to carry out a certain amount of documented 'continued professional development' or CPD each year to maintain their professional status. This may be achieved by inhouse courses/training by their own employer, by visiting conferences or external training or by attending even9ing lectures from learned societies. I used to take advantage of foreign holidays to visit installations (like dams, canals or bridges) of interest. It is suprising what the local custodian will show you around if you ask. There are many ways you can be creative about this.

OK so to move forward waves, or more properly wave motion. Which brings up the subject of motion, something you will have met in Newton's Laws (of motion - he discovered many othe Laws) . Motion is a process. There are several forms of motion. Rectilinear motion (motion in a straight line) , curvylinear motion (motion in a curve) , wave motion ( we will come to that) And we usually describe processes by equations so it is a good idea to become familiar with equations. The equations that describe motion connect space and time. The simplest such equation is distance = speed x time or distance = velocity x time. Do you understand the concept of 'rate of change' ? Processes are about change of something Again the more you tell us about what you already know the better the answer will be. Since waves are also a process they obey an equation connecting space and time. Knowledge of these basic process equations of motion lead to knowledge about properties such as energy, momentum, power, mass transfer and others.

So you didn't read the rules that here you signed up to before you posted . I should not have to go off site to read the substance of your query or hypothesis.

A mathematical fact. You have exactly 5 posts available in your first 24 hours so it is unwise to waste them. You could add to post number 3 something useful and on topic by way of the edit post function, available by clicking on the 3 dots in the top right hand corner of your post. More than one member has now said post the maths you offered.

Maybe not very proficient in Physics but asking the right questions, which shows you are thinking about it. For instance wondering why the electron does not fall into the nucleus shows you have taken in some mechanics and electric theory. OK a small aside, whuich I think will be helpful. Your written English is good but considering your posting times I don't know if it is your first language or you are using a translator. I tend to write long complicated sentences, but I will try to keep them shorter if you need this. English is a very good language for Science. But Science sometimes needs more tightly controlled definitions so it often takes an English word, but uses it in a very specific way. English distinguishes between things or objects (nouns) and words of doing or activity (verbs) and words which qualitfy or modify basic objects or actions (adjectives and adverbs). English further recognises that nouns may be 'abstract' or 'concrete'. In Science this distinction becomes material (eg a pile of sand) or non material (eg a shadow or a force). Such nouns may be real on non real whcih is more difficult to tie down. But broadly speaking something is real if it can affect or interact with something abstract or concrete that is real. So you might be colder or drier or both if you stand in a shadow. So 'real' is an adjectivit;, the noun reality is often misused. In Science verbs become processes or actions but 'action' also has a restriced scientific meaning all of its own. Enough blather. I will deal with one more basic piece of nomenclature this time. Matter is the name given to material objects. Most scientific treatments of matter work by considering matter as made of 'particles'. Chemists, by and large, work with particles that are the size of atoms or larger. Physicists work with sub atomic particles (smaller than atoms). The science of mechanics works with particles of indeterminate size, but provides the definition, of sufficiently small size that all the properties under consideration may be considered as concentrated at one point. These are called 'point particles' But there is also much Science that draws from several branches of Science. You mentioned substances. Chemists identify lots of different substances and in particular pure substances where all particles are identical. Each different chemical substance corresponds to a different chemical particle called a molecule. If those particles are individual atoms then the substance is called an element. We know of getting on for 150 differements elements. Some elements also combine atoms of the same element to make molecules. Hopefully this preamb;le will become useful in your studies.

Here is another version of the Monty Hall question. A mathematician has two children. You ask if at least one of them is a boy. She answers yes, at least one of my children is a boy. So what are the chances that she is a mother of two boys ? This version demonstrates very clearly that it depends upon what question you ask to what the chances are. @KJW if you answer this please put the answer in a spoiler.

Thank you for bringing this up, although I feel it is a tad off topic. +1 I also feel it deserves a thread all of its own What do you think ? Here is a short excerpt from a recent book about statistics that may also be of interest about the nature of scientific papers in general.

Then post it if you want to discuss it. Otherwise there is nothing to discuss and this thread is done.

Otherwise there would not be big boys and little boys.

Welcome Modafinil. We have an introduce yourself thread https://scienceforums.net/topic/75313-the-official-introduce-yourself-thread/ It would be most helpful in answering your quesry if you visited this thread and gave us a pointer as to where you are coming from with this. Have you studied or are you studying Mechanics, where the difference between Matter and Energy is spelled out ? They are not exactly interchangeable, though one often leads to the other. But framing an answer is difficult wthout some idea of what you already know, especially since you equation (do you know about equations ?) is only part of the story, and you have an incomplete version of the equation.

Hello arc, welcome back. Kinda difficult to follow you graphs as they seem to cover all sorts of timescales. But I did pick this out. This shows a steady temperatiure 2010 - 2024 and entirely misses the local minimum shown by this one over the same time period.
