Phi is most used for a general or unknown angle, both in calculus and other uses of angles in Mathematics. The Golden Ratio is also known as the Golden Section and appears in mny places in maths and natural science, as Joigus says. Associated with the Golden section or ratio is the Golden Angle.

I am going to say +1 for this correct stetement. Time is indeed not a vector, but then I don't know who said it was. I further can't figure out what you speculation is or why this is in speculations at all. The whole classification scheme of scalars, vectors, tensors, dyads, triads and so on is a bit fuzzy so it is important to know whether you are talking mathematics or physics as they are different. Also a quantity can be a scalar in one situation andn a vector in another, which make matters even more complicated. Equally there are situations where time may be considered a parameter, a scalar, a dimension or something else entirely. So it is not a case of one or the other.

I saw this alleged response the first time and understood your description. Then I couldn't see how this addresses my query about symmetry and I still can't detect any refernce to symmetry in your reply. Am I being thick or what ?

Coincidences occur both in calculations involving units as well as numbers and calculations involving only numbers. For instance If I buy rope as 1 shilling a foot the units are 1 per 1. By a strange coincidence that is also 1 penny per inch : again 1 per 1. Or think about area; an area 3 feet by 3 feet makes 9 square feet or 1 square yard - not a coincidence and also not very useful to measure electron areas How about working in Barns ? Of course we can do without units 23 is approximately equal to 32. or better 32 + 42 = 52 and the net abounds with other coincidences By the way I am still waiting for a response this my question. I originally had some trouble downloading your 5-page paper, but I have now managed to do this. But if you will not read a 5- line reply from me, why should I read a 5-page paper from you ? Can you point me to the page and paragraph that contains the answer to my question ?

Looking back over the years SF averages at least one thread per year about concidence/numerology in maths http://blogs.scienceforums.net/ajb/2011/10/17/number-theory-and-numerology/ http://blogs.scienceforums.net/ajb/2011/10/17/number-theory-and-numerology/ and many more. The answer has never wavered.

Proof is a high bar. Evidence for and against, along with argument of interpretation, is the best you can ever go for. But that's fine. For example, the world is spending trillions, without proof, that the CO2 levels will cause damaging climate change. I haven't heard one politician provide that proof or even call for it. What you can do is show what is illogical and downright silly, about the notion of design, and illustrate what kind of odds are in place, for and against there being an intelligent designer. Religious people often use the way out that "god moves in mysterious ways". I believe it can be shown that if he exists, he moves in incredibly stupid ways. Look again, I didn't say that, not quite sure how you managed to attribute Markus' comment to me. I was, in fact, musing on where something very similar to your suggestion/question is successfully attempted in physics and wondering if that template might in some way to your heart's desire. Yes, the London Eye is so much better, If speeded up the fan effext will even deal with global warming in London. 😀 p s I used to be able to increase the font size of a smiley, but it doesn't work any more.

I put the 'the 5 senses' in inverted commas to show that I did not accept that there are only 5 senses but was referring to someone else's classification. Perhaps it wouold be clearer if I made the commas bigger? I could say alcohol or I could say that as I understand the mechanism of balance it involves interaction with the environment by visual clues (sense 1) and measuring pressure/ pressure difference (sense 2) as well as feeling gravity.

Thank you for replying as someone who has actually seen it. The presenter, Chris Packham is a journalist, not a scientist and did a creditable job of presenting the material. So yes I enjoyed it. The episodes included short 'interviews' with a range of academic specialists from around the world. I especially liked the new material about Funghi and their fossil tree like growths that everyone thought were fossil trees. However I noted discrepancies between some of the episodes. So at the end of episode 2 they had rushed timeline forward several billion years to -700 million years and announced that in the next episode they would be taking it from there to discuss life and its great proliferation. Yet in episode 3 they barely reached -700 million years, yet kept jumping forwards to show magical open sky margins around tree tops, that I do not recognise from any forest I have ever been in, and made the claim that funghi, which they reckoned once towered over plant life once were relegated to the ground at this time. Yet all the pruning theory for trees and bushes tell us to 'open out the top area' so as to avoid colonisation by -- yes -- funghi and lichens (these latter did not merit amention in the programme).

Has anyone been watching the new BBC2 series Earth, presented by Chris Packham ? I wonder what you made of it ? I thought it had some new thought provoking ideas but found some thi ngs rather difficult to follow. It has not been clear what is established and what is hypothesis. The programmes jump backwards and forwards along the timeline so it is difficult to place material presented in context or connection with other material either in the series or elsewhere.

+1 to Markus. The actual definition of a geodesic is lost somewhere in the Terra Incognita of algebraic geometry - I have several all pretty impenetrable jungle. Here is the beginning of a good introduction for Relativists from this book.

Perhaps a nice one, but aren't 'the 5 senses' to do with the interaction between us and the rest of the universe ? And aren't bathroom visits due to internal proceses ?

Definitely. Another +1 to Mac. Well sort of, but I am not so sure that there might not be a way to prove the negative. In this thread I posted an analysis using Newtons Laws of Dynamics, (post 22) which goes some way towards achieving this for an entirely different purpose. I.m sorry I can't That we can separate the effects of external influence and internal process is all to often taken for granted ( and not always true either). Even Newton invoked it but did not explicitly state it.

You are just demonstrating ignorance of the way statistics and probability (they are not the same thing) work. Probabilities of 1 and 0 have special meanings, not possessed or needed by inbetween probabilities. Most people who think they know statistics are unaware of this. I wish I had £1 for each time I have pointed out on this forum alone that the 3 special meanings of a probability of 1 for instance are taught on the UK GCSE syllabus.

The odds against the first living creature are, by definition, zero since it happened.

Isn't that also true for the word Tennessee ?

Since you have posted this in a true science section I suggest you go and learn the most basic law of 'chance'. An event with a definable probability, no matter how small, could be the next event in a probability space, no matter how unlikely that may be.

Having already acknowledged that your 3 electron radii are not all electron radii, I am disappointed you have not made the relevant correction either to your paper or to your postings here. In fact more "loose wording" has been pointed out by others. Also I don't know whether your speculation is mathematical or physical ? In other words can you provide a some physical reasoning as to why an electron might present as a two dimensional surface with less symmetry than a true spherical one. I worry about this because some behaviour of observed quantum mechanics (in spectroscopy for example) relies on the assumed spherical symmetry of the electron. That is it has no preferred direction in 3D space.

Welcome you seem to be observing the rules here and I for one woulf like to view you speculation. However I am puzzled by your introduction since my understanding of the Bohr radius is that it is an orbital radius. The other two, of course, refer to measures of the electron size in interactions.

I understand jellyfish can learn, despite having no brain. How does that play with theories of intelligence and consciousness? https://neurosciencenews.com/jellyfish-learning-memory-23967/

Where else would the end be nigh ? 😀

Because that is incoherent nonsense lacking further contextual parallels. I was intending to discuss natural and artificial patterns with you, since you introduced them, and following Markus great example. However I see your response to a patently true statment is an obvious falsehood so I am out of here.

This is a Science site. Which means we use scientific definitions where appropriate. And that does not include correspondence, which is another concept with a special scientific meaning. If you wish to promote mystic woo then I suggest a religous site, rather than coming here and calling another members comments silly.

Please think about your use of the word coincidence. All that it means is that wo or more things happen in the same place and/or at the same time. Since there are billions upon billions of things happening at the same time and or place at every time and place and each and every one of them is a coincidence there is nothing special about this.

Indeed. But this is an analysis of Newtonian gravity. Have you given up on this subject? We can now make a start on analysing your thought experiment, from first principles. We will need a coordinate system with an origin that we can define along with a sign convention. This situation is very common in mechanics and the sign convention is often not mentioned. But it is very useful as it tells us which way thing are moving an also since we don't necessarily know all the directions at the outset, it tell us if our initial guesses (assignments) are correct or not. OK so the attachment offers all this for two particles moving only along the x axis. The sign convention is that left to right is positive. I have drawn the most general situation in which both particles have a velocity and two forces acting on them. One of these forces is an external force the other shows an interaction force between the particles for each particle. If our assumed directions turn out to be not as shown then the particular forces or velocities will be negative, not positive. First we write Newton's second law equation for each particle in the form force = rate of change of momentum. Remembering back to simple differentiation we can add these equations up as shown, since the derivative of a sum is the sum of the derivatives. After adding them up we bring Newton's third law into play to show a very important fact. The total momentum change due to the total external forces is unaffected by the mutual interaction. This is of course conservation of momentum. Note a similar argument applies in statics to allow us to discount all the internal forces of a system and only work with the external loads. I have also included the position of the Centre of Mass, at a distance from the origin, in preparation for the next stage in the analysis.
