Thank you once again for pointing to a most interesting and thought provoking investigation. The idea of continental delamination but rising hot magma was originally proposed by P Bird in 1979 as an explanation of the Labrador trough. Here is a reference to this http://peterbird.name/publications/1979_delamination/1979_delamination.htm This was extended in 1981 by Dimroth as in this diagram. As discussion (references later) has since caused this approach to be discarded as no one has been able to make the necessary heat flows add up. See the discussion also in the scan. Further explanations are also introduced and discussed. The scan is from my copy of Global Tectonics by Kearey and Vine 2n ed I note that there is now a 3rd ed with nearly 200 extra pages. A (free) pdf is available here https://www.geokniga.org/bookfiles/geokniga-global-tectonics.pdf warning it is 66MB The conventional explanation, based on the Wilson cycle of breakup of continental crust (cratons) is greatly expand and firmly entrenched in the £rd ed. But it really is an excellent text as it examines the conditions of tectonic process as applied to the real earth geology and geography, including the mineralogical and rheological environments. A final picture towards our next exchange from Wikipedia. The real earth examples in the Nature article all relate to the breakup of the last supercontinent, Panges. So we need to go back about 200Mya and start there, because the examples did not all occur at the same time but over a period of about 200Mya to 50 Mya.

I really think it would be a good idea to try to focus your question. Take a look at this website and see if this is what you are really asking about. Then ask a few more detailed questions. https://www.cloudflare.com/en-gb/learning/ddos/glossary/open-systems-interconnection-model-osi/ Please note the statement Layer 7 The application layer. I am also going to say +1 for encouragement as this is a much more reasonable thread than some of your earlier ones and much more in tune with ScienceForums. We can actually help you with this one rather than argue.

Here is another viewpoint, but covering the whole globe. I note the Indian and african examples the raised upland is 'protected' from eroding rainfall by the escarpment mountains. https://orca.cardiff.ac.uk/id/eprint/56857/1/Blenkinsop%2C Moore - 2013 - Tectonic Geomorphology of Passive Margins and Continental Hinterlands.pdf

This is a good topic for you to do some experimentation on your own. For instance you seem to be suggesting that a steel ball felt heavier than a piece of wood. Take a short length of wood etcf eg a rule Spread out one hand and lay the rule across all the fingers of that hand. Now low some fingers, one at a time. Does the ruler feel any different as you do this ? One thing to remember is that our brain/nervous system receives an enormous amount of sense data. All our sense data is filtered so that only some reaches the brain. For instance can you feel the pressure of the ground on your feet ?

You want a 5 year course in computer engineering put into a nutshell on a discussion forum ? From your question paragraph you seem to be leaning towards hardware. Are you aware of the distinction between hardware and software or the layer model of computers ?

That was not 'my perception' at all. Please go back and read carefully what I wrote. You actually asked a question along the lines of 'What happened to the magnetic field ?' I answered this question. So please stop saying I have since answered another of your questions, which answer you have again ignored. Now here are two questions of mine What is you understanding of a diamagnetic material ? All materials, without exception, are diamagnetic. In some materials paramagnetism or its stronger cousin ferromagnetism swamp this diamagnetic effect. The interaction between a magnetic field and a material object can be viewed or classified according to the effect on the material object or the effect on the magnetic field. Both of these views must obviously 'match up'. The dia, para and ferro classification was introduced by Faraday's original work, when they had no means of probing the magentic field so he went for the effects on the material object. Later workersdeveloped means of probing the field and the so they are usually now described in terms of the effects on the magnetic field. But, of course they match up. Secondly can you explain what you mean by this ? Finally I don't know who removed the link in your original post but I can't find it now so have to rely on memory of that original bunch of videos you linked to.

Firefox This doesn't happen on any other website, just SF, by the way.

I'm not having trouble with the posting action itself, but this is the sort of thing I see over 50% of the time when I try to move to a differnt page on the website eg from the browse tab to the activity tab. Now the ad box goes away if I left click outside the box and I am returned to the original page, not the new one I requested. But the second request then sends me to the correct page. I agree it is annoying and hampers the flow of usage. Note the page address changes in the address bar with the addition of google vignette

The word rift or rifting occurs 5 times in the abstract alone!

Isn't it just! and full of techie words with special meanings. So first thoughts. I have not experience of the escarpments the authors are describing. The onlymega one I have direct personal experience of is the Arabian peninsula escarpment. That is definitely a rift valley escarpment, still active today. It is estimated at 30 Myears old. The continental plates have shifted a long way inthe over 200Myears they are talking about, and oceans have opened and closed. So their comment that these escarpments occur at continental edges and are one sided (unlike a rift vally) may have occurred due to plate displacement over the timescale. One thing the new theory does not explain is the lack of deltas at the continental margins, building up new sedimentary land as England was built up on the edge of the Scottish peninsula of the old red continent. There are many small escarpments from the brecon Beacons to the Kentish Weald. I'm not saying I think it is wrong, just that there is room in our world for many different mechanisms and routes to escarpments and flat topped raised areas.

Well I think you have a case of positive or negative mutual inductance in the transformer, depending upon which way round the coils and jumper are connected. The total inductance is given by Lt = L1 + l2 ± 2 M when you connect the coils via your jumper or resistor, Where L1 and L2 are the individual coils inductances and M is their mutual inductance. I have been doing you the courtesy of taking seriously what you are showing, whilst taking the trouble to understand the connections. Please do the same for professional Engineers you have been consistently disparaging. I am a retired applied Mathemaician, not an electrical engineer, which means I have done a considerable amount of electrical calculations in my time. In one of your videos you asked acted incredulous about the fan continuing to work when you introduced an air gap, but have shown no interest in the elementary theory of air gaps and their effects that I posted last time.

It isn't only drugs that should be considered. So I don't know if the FDA is the only or appropriate body to be considered. Many substances, common in the past, have since been found to be carcinogenic. My toothpaste example is one such, another would be Benzene, another would be AMC (since we are talking in journalistic acronyms) or Amyl Meta Cresol.

What is an enormous electron wave ? Surely you are mixing up the x and y axes ?

Out of body experience. 😀

Interesting, thanks, +1 I will comment further once I've read it properly.

I suppose thalidomide would be the classic example of why the FDA is so tough, but there are others such as hexachlorophene toothpaste.

The air gap Your subject is best approached from a Technician engineer level, not advanced physics like Maxwell. Here is an extract from the best technician testbook I know which shows quite clearly enough how an airgap can increase the inductance of a winding. I have starred the importance sections.

Even if you didn't want to reply to my earlier comment, Please, Please, Please don't tell me you want medics to test new drugs and treatments on people the way IT firms fail to test properly on their customers. Or would you like they medics put out a half working drug, like a half working operating system ?

Yes this new demo appears much closer to the circuit diagram you drew. As swansont (congrats by the way for scoring the winning goal in the olympics today 😀) has already said So what exact question are you asking ?

As with all statistics bandied about, especially by journalists, one must learn to interpret them with a critical eye. Firstly the question of the population base at the beginning and end of the sampling decade. Is this the same ? Secondly have there been any unusual interfering events during that decade? The answer to the first is no, the populationat the start and finish are not the same as medicine attempts more and more difficult ancer conditions. The answer to the second is that the decade 2014 to 2024 included the covid years which considerably distorts the data for most treatments.

Perhaps this way ? Even if not the pictures are pretty. https://www.chemistryworld.com/news/hand-built-caesium-based-artificial-atoms-used-to-create-synthetic-benzene/4017567.article

I've been away again but here is a quick answer. Sorry I should have corrected the use of the word surface to hypersurface since we are talking about ll manner of dimensionality, including beyond 3. I amt talking about causality, which is a physical property, not a mathematical one. I am warning about loss/restriction of information when you choose a subspace or manifold to work in. For instance The is no such thing as a tangent (at any one point) to a curve or derivative of a function in one dimension. There is only one tangent to a curve (at any one point) or derivative in two dimensions. When we get to three dimensions we have to ask the question "Which Tangent ?" and "Which Direction ?" since there is an infinity of tangents and the derivative becomes a directionsal derivative. So we can happily take a plane as a subspace of a solid, so long as we work only in that plane.

Thanks to those who liked my input. Considering the instructions as to the purpose of the Religous section of ScienceForums I thought that some might have an interest in my sources. Anyway here is a book that attempts proper scientific evaluation of some of the stories in the Bible, including on site investigation, analyses and references.

You posted a circuit diagram which is a standard language for engineers (and others) in this discipline. Two coils arranged against three solid lines has a specific meaning. If you don't know about this, we are happy to help, but that just as everyone must use the same meaning for yes, no, red, black and so on in (written) English in order to communicate everyone must use the same standard symbols in circuit schematics . I am well aware that magnetic amplifiers are not transformers and do not require a lecture on the subject. If your device has two coils and an iron core and is being used in some other manner than a transformer, please show what is actually meant. Yet you express suprise that a DC motor will run on AC. A series wound DC motor will run on AC A shunt wound motor will not and may be damaged. I can't tell what sort of motor it is from the videos. But I do know that it is not a transformer. I saw whatever was on the videos in your link, and yes I saw two motors. But motors do not have primary and secondary windings. I did not see any transformers. The way forward is to take one circuit or configuration at a time and analyse it, not jump around between several different ones.
