    Gravity

    Surely by that idea gravity would be related to volume rather than mass? And as it is related to mass not volume then your idea is in problems
  4. I think it is also that if you hold as true that changes in an effect propagate and that this propagation (indeed any causal transmission of information) is limited in speed then you get a "change-front" spreading from the source. This part is strictly analogous with the model for electromagnetic radiation - and the famous picture of the charge with "rays" spreading out and when the charge moves all the lines have a kink (except for +ve /-ve direction of motion). What is different is what the propagation of the change is manifest through, and what physical changes in orientation cause a change in effect. That these "change-fronts" which we know are gravitational waves must carry energy away is a result of the EFE I believe
  5. ! Moderator Note David Levy This thread will go nowhere till you stop immediately responding to posts and instead start trying to understand the ideas before typing. If the thread continues in this current direction - ie if you continue with your lack of real engagement - I will lock the thread. And for crying out loud stop with the patronising lecturing tone and the idiotic use of the rhetorical. It would be annoying and insulting from a Professor of Astrophysics - from a forum poster who started the thread not understanding the concept of the observable universe it is infuriating and trollish. If you post "do you agree" before totally misrepresenting/misunderstanding someone's idea then I would not be at all surprised if the post just gets trash-canned. Do not respond to this moderation within the thread
  6. That shows that there cannot be a local hidden variable which would reproduce the results we get from Quantum Mechanics. But there is nothing that makes us think that entanglement allows superluminal communication. By communication we mean the transmission of information of any sort. What happens when one of two particles which are entangled into sharing a state of superposition is measured is not communication - the effect is not local but no new knowledge is gleaned, nor is information transmitted
  7. The surface area of the bands of a sphere depend only on the height of the band* - so easier than your circle mathematically ; I proved this further up the thread. How you would go about changing this into a computer image; you are on your own - frankly I would have a better chance of translating it into Sanskrit than into code *to explain further. If you have a sphere with bands which correspond to equal divisions of height - ie if you marked the axis at 1 unit intervals and extended the banding out to the surface then all the bands would have equal area. To get the coordinates (rectangular) is pretty simple - imagine a unit sphere with centre at the origin and horizontal bands. nb orientated normally - ie x +ve towards you, y horizontal +ve to right, and z vertical +ve upwards). The height up and down the z axis directly corresponds to the areas of the bands Work out your first z coordinate (which would be z1=1-percentage of sphere in band one) You then have a right triangle on the zy plane with one side equal to z1 the hypotenuse equal to radius. It is on the zy plane so x1=0 Pythagoras then gives you the third side. This third side is y1 You have the first point x1,y1,z1 on your circle around the sphere Mathematically as you know the axis (z axis) and you have a point on the sphere you now have a unique circle on the sphere
  8. I expected he will be shocked by the knighthood Select, Ctrl-C, "www.wolframalpha.com", Ctrl-V, "factors",return , Select Plain text output, Select, Ctrl-C, Ctrl-V 23 pages for the prime factor of 125! I am not sure dropbox will allow a big enough file size to print out your calculation for Strange's challenge
  9. There is no superluminal communication
  10. You are still a running dog lackey of the capitalist-imperialist oppressors; but then most of my best friends fall into that category :-D It was just that I thought you were posting views that were markedly more right wing than normal; I thought then and I think now that a bit of your motivation was to provide a balance to the overwhelmingly left-leaning posts in politics. The "right" (and not just the hard right) do not need help - their message is broadcast load and clear, and their agenda has been almost fulfilled. No-one in their right mind would call for kangeroo courts or draconian punishments for policemen in these situations - no one who thinks about it should even contemplate anything less than a textbook case with all the amazing procedural safeguards (these safeguards are for the defendant by the way), the evidential scrutiny, and the judgment of one's peers. The problem with Missouri is that a clear executive decision was made to present an underwhelming, poorly researched, potentially biased, and terrifically misdirected case to a grand jury. This was wrong on so many levels - firstly the grand jury is not a properly instituted arbiter of guilt or innocence, and secondly administrative arbitrary action should be taken or not taken - but if it is taken then it should be done properly; ie make the choice whether to go to a grand jury or not (that is the DA's choice) but once you go to a grand jury you must put a required amount of effort in and treat all cases with the same level of expertise and care and - yes; for one thing the site would be much poorer without you

    Gravity

    So I got up early cycled to St Pancras International Station, Eurostar to Paris, cab from Gare du Nord to the Eiffel Tower, climbed 1700 steps and a lift up the final section - and one question sprang to mind - WHERE THE F@~K is PHI?
  12. Your comprehension of the written word needs improving this is what I posted Did you forget that the major import of the modnote directed towards you was to stop making personal arguments? The final section is not even addressed to you My second modnote concentrated on asking you not to argue moderation (still going after this time) but more importantly to stop being abusive . The final modnote again asked you to stop commenting on moderation and asked you to back up a position or resile from it. Your warnings were for soapboxing (you implicitly mention within the thread that you are doing this) but mainly for responding to moderation when explicitly told not to, and most importantly for making personal characterisations and attacks when previously and recently warned not to do this.
  13. I tend to view the court in the same indulgent manner that the NRA view guns - "guns don't kill people - people kill people"; the courts are a tool that can be used for good or for ill. For all the negative actions of the US courts one must hold in mind some of the amazing positive actions taken by those courts when the executive and legislature were too craven to act or unwilling to advance a progressive positive agenda. From personal experience I would disagree utterly with the notion that they wish to be an entity detached from the other wings of government - the people of the court love the rarefied simplicity and deliberate constraint; they will answer very simple questions using elaborately complex protocols but run in fear if you ask them to answer anything complex in and of itself. It is both mark of the success of the court and will be the root of their failure that this excessive simplification of real life to a series of questions amenable to resolution has spread to the world outside the courts. The more the courts have to deal with, and the more law has to engage with everyday questions then the less those within the courts can hide behind their protocols and rules and the more accountable they can be held for procedurally correct but substantively wrong decisions. I think a classics scholar would interpret "Idiocracy" as rule by that which is not known or rule which pertains only to the individual case - both of which are entirely apposite
  14. A Brief History of Time was by just Hawking - it is the updated Briefer History which had the collaboration with Mlodinow. I think that Hawking - whilst an excellent writer and better theoretician - makes too many unsupportable analogies and easily grasped but fundamentally flawed heuristics (Brian Greene too). I would probably recommend Chad Orzel's Dog books as the best introductions at a pop-sci level.
  15. Maybe all those adverts on the buses about the Republic of Yorkshire (John Smiths, Tetley?) from a while back will finally come to fruitition
  16. Has someone taken over your account? You are posting reactionary rubbish recently. Who said 'extra vigorously' - it is in quotes so I presume someone other than you typed it first? The closest is in my post "We hope that Alabama will prepare the case for the Grand Jury with a bit more vigour and rigour than Missouri did". As this was a thread about Ferguson and the grand jury presentation by the Missouri state prosecutor was roundly condemned as both slipshod and clearly hopeful for no indictment - then a call for 'a bit more vigour and rigour' is merely asking for a decent job to be done. And yes I have looked at the sparse facts available and even more I realise what a grand jury is for - perhaps you don't; and I am serious peeved about being accused of having a lynch mob mentality merely for wanting a criminal trial (with all its procedural safeguards) to establish the truth of the matter. FFS - what on earth makes you think that the following is even close to happening? "I hope the scales of justice aren't being weighed on the opposite side to make up for past ( and continuing ) injustice against black Americans."
  17. You will get zero net angular momentum gain - by principle you need a torque about an axis to get a change in angular momentum about that axis; you can use counter-rotators which will have balancing and opposite ang moms - but no net angular momentum gain. You will have a linear momentum gain away from the star purely due to radiative pressure - have you done any back of the envelope calcs to see if the velocity you can achieve thru your wizardry can overcome the velocity you will get thru radiative pressure? NB - It is an urban myth that you can not use a propeller to driven by the wind to move into the wind; check out all the designs that do just that on youtube. Note the designs are very clever and not quite what you might imagine. So I would not immediately rule out your idea - but you gotta do sum sums
  18. To an extent- but mainly it is just that UKIP are a bunch of ... (I don't want to be the first moderator to get suspended for foul language so I will stop there)
  19. I think a very large impact would be on the Union - not the new fangled European variety - the original one formed by the Act of Union of 1706/1707 between England and Scotland. Scotland voted to stay within the Union barely very recently and a move by the UK out of the EU would almost certainly herald unstoppable calls for a second referendum. This would be successful for the Independence campaign (obviously there is uncertainty but based on polls, personal knowledge, etc...). England without Scotland would become increasingly right-wing and London-centric, Wales and Northern Ireland would call for greater devolution from Westminster, the disparity between the South and North would be ever more marked. There will not really be a UK outside the EU - if there is an exit then there won't be a UK for long after that
  20. Some of them behave like they don't have a heart, others just don't have the stomach for job, too many have serious voids where the brain should be, backbone is often found to be lacking, and almost all must have (metaphorical in some cases) cojones like watermelons to think they can get away with doing such a poor job. I have seen upper houses in which a fair number would fail the mirror/breath test, I am pretty sure that half the UK cabinet are poikilothermic, in most politicians their endocrine systems seem to have been rejigged to work off levels of press coverage rather than hormones, and in general terms to keep themselve going instead of ATP they work on FPTP
  21. I guess there would be a single pulse / single step along with the pulse of EMR. If a Nova converted say 5% of mass to EMR then whilst you the observer had not noticed the Supernova because the light had not yet reached you then the mass-energy would be constant (ie all the mass energy would be in a sphere closer to the Star than you) but as the pulse of EMR passed you then a portion the mass energy would be in a shell outside your orbit around the now cooling star. According to Newton's Shell / Gauss' Law of Gravity spherically symmetrical shells outside the radius of the observer do not get felt by the interior observer. The attractive force felt by you would diminish in a step as the EMR passed - I guess; if you hadn't been burnt to a crisp and if you had time to look at your instruments and tear your eyes away from the storm-front of approaching plasma about to engulf you
  22. However I cannot see how the craft would remain steady in space - linear momentum must be conserved. And I do not understand how this could possibly create a usable motion that is preferable to a simple solar sail. You could place one in orbit around sun to harvest a tiny amount of energy - but a simple photovoltaic would surely be better
  23. Not endorsing the idea - but two counter-rotating mills would sort that problem pretty simply. there would be no net gain in angular momentum and thus the space-craft would/must stay stationary
  24. Quite a few of the older Republicans I talk to on a daily basis would agree almost completely with the above - the only candidates for the nomination they would positively support are already out of the running (or never even made it to the start line) and the two Senators both seem equally unappealing (although for completely opposite reasons). They dislike Trump - but not as much as they fear the ideologues of the christian right nor as much as they hate the obstructionist GOP neocon elite who have brought the party to this position; and they have no positive feelings and plenty of negative towards the appointed candidates of these two wings of the neo-republican party. Before the primary season began I taunted them saying they would end up voting for Clinton as she best represented the Centre-Right viewpoint of their heroes (Reagan etc. And don't ask me why - I have never understood his beatification) - now I have stopped this mockery because they are starting to think that this may well come to pass and it is cruel to mock the afflicted. Have we seen any recent / decent polls for Fla. Latest one the Nate Silver (who I rely on utterly) is fairly smaller and old? Trump given a fair margin - 8-9% on Nates projected results.
  25. Only five of the current justices would be allowed to serve in UK courts due to age - and another two or three would be kicked off for being complete and utter bozos
