  1. Alan - I dont have time right now to go through but I am not sure you do have the rught idea. Tony is of course correct - there has to be some reference to the size of the world. At a quick glance I think d is a distance measured as a ratio of distance travelled over radius of earth. this for small angles will give the radian angle at centre of earth. you will note that your equation has sin and cos d - this only really makes sense if they are angles. Will have a look later - or maybe you can work through an example and see if the sums tally.
  2. Alan this looks a useful set of ideas http://mathforum.org/library/drmath/sets/select/dm_lat_long.html one of which might help
  3. - the famous (is/ought) problem = should be/ has to be . The point is that you agree to be bound by the document upon which you have appended it; and that the signature is personal to you.
  4. I hope it was Oscar that said it first - everything I have read about and by GBS makes me think he was an insufferable bighead and not fun to be around; whereas Oscar would be a bit of a laugh, if a little dangerous
  5. But, dear Oscar was "a bit of a one" for recycling other people's bons mots; when Whistler made a particularly clever remark Wilde reportedly said "I wish I had said that", Whistler retorted "You will, Oscar, you will"
  6. who is gonna check and how? It's a scribble on a piece of paper that you confirm is yours and by which you affirm your agreement to the preceding, famously it could be just a mark or cross. As an example - my father's signature was the forename he used followed by a squiggle; this forename was a nickname that he acquired in the air force and never changed - it had no 'legal' connexion with him whatsoever. As a second example; I receive a huge amount of correspondence with the company name "signed" at the bottom - lots of law firms adopt this procedure
  7. Ewmon - you're correct that some companies will ask for handwriting, I was, but then my company is basically American so your second point is not quite right. Whilst agreeing that the more continuous and flowing the signature is, the harder to forge; it is by no means the case that the signature must be readable. All important documents will have a signature block which will contain name, (position), date, and signature - the really important ones have witness sections as well. There is no way you could work out my surname from my signature, yet it is acceptable for setting up of trusts and companies, signing of contracts, and confirmations of transfers. I know of a few individuals for whom it was impossible to tell which alphabet they using in their signature - let alone what it said. To the OP - people shouldn't judge you on things like your signature, but it is human nature to do so. It is not necessary to be fancy, nor flamboyant but it should be consistent, fairly complex, and second nature to you. And final point - if you think your signature is going to be forged - then do something about it! fancy curvy signatures in real ink pens are no protection - take precautions, understand the circumstances that your bank, company, lawyers etc will accept instructions under a plain signature and change them!
  8. How GBS would react to being equated with a half English/half American aristocratic demogogue I shudder to think - but his reaction would be scornful and witty!
  9. Just reading through the last few days of this thread - BTW "two peoples separated by a common language." - was George Bernard Shaw.
  10. Your slip up was here 8 corners ( 4 per face each shared by 3 faces 24/3=8) , 36 side pieces (12 per face - each shared by two faces 72/2=36), 54 mid pieces (9 per face), and 27 interior pieces (3*3*3) 8+36+54+27 =125 However! You cannot touch the interior faces - unless this is some new form of touch that involves my finger going straight through a solid object. Any answer that deals with internal cubes seems to me a bit screwy - the question clearly stated - and Rubik's cubes do not have internal cubes, that's where the mechanism is. Therefore all sums should work on the 98 cubes that you can actually touch. [(8/98)*(3/97)]+[(36/98)*(4/97)]+[(54/98)*(4/97)] = (8.3+36.4+54.4)/(97.98) = 384/9506 = 0.040396
  11. Leeder Bee - try Birkbeck - http://www.bbk.ac.uk/. Birkbeck is purely for mature students (at present), but mature starts quite young as Rhiaden says above. There are practically no entry requirements, apart from interviews and assessments; the degrees are all internal University of London (so not mickey mouse) and in some departments they are world respected. The great advantage over Open (which is great as well) is that the Birkbeck courses are not distance learning - they are normal attendance-based, but in the evenings. It's a shattering schedule, work 9am-5pm, college , 6pm-9pm, and study every free minute; but there is a great social side that will provide the necessary peer-support and beer-support! If you want more info about it drop me a pm (there are private messages on this forum aren't there?) - I studied undergrad and post-grad at Birkbeck
  12. Doublerainbow - done your survey. Tiny hint: your age ranges are screwed - 30 and 40 appear in two categories; if I noticed it your teacher/marker probably will as well.
  13. Rigney - you started typing the sentence "I do not see how anyone...." without a space after the link. Therefore if you click the link it error 404s because it has :I appended to the end or the url. I realise I was more than a little cryptic... You have a good one too
  14. For those of you that have been following the Registers PARIS mission - updates and pictures galore here. PARIS page Congrats to all involved. PARIS involved building a paper plane that could be launched from a weather balloon at high altitude.
  15. Yes - I am really against the death sentence for these people - without even opening the link I am opposed to them being condemned to death. I am not going to enter the debate - mainly because these are deeply ingrained personal ethics that do not really translate to a forum debate; but I did want to let you know that many people have thought long and hard about cases such as these and remain opposed to any form of judicial death sentence for any crime. PS you might want to edit the link - your ":I" are too close and forming part of the url and stop automatic opening of link
  16. Michel - yes, to an extent. But I can guarantee that the electric circuits (whatever they are doing) in the bose headphones they give out on american airlines make a noticeable difference on the roar of the jet. They have a switch to turn on the power so you can flip from on to off (ie from just physical soundproofing to active in addition) - and whilst voices are almost unchanged (which tallies with your quote above) the low drone of the engines is considerable reduced. .
  17. Not feasible - quite agree. But are they possible, (money no object)? They work in headphones - Bose and Sennheiser make a fortune selling noise cancelling headphones because they work. Could not an array of microphones around bed allow a fairly accurate model of the incoming sound waves to be made and feed information to processor to produce signal for speakers to create noise-cancelling out of phase sound.
  18. Demonio - but surely the dark matter is not causing expansion. dark matter was predicted to make up for the fact that there is too little apparent mass in orbiting galaxies within large clusters. dark matter is the unknown and unseen matter that makes up the difference between the measurable mass of the universe and the calculations. now dark energy is a different matter - that is an intellectual construct to stand in for the fact that we don't understand the large scale large time expansion rate of the universe
  19. open bracket c close bracket = © ie it gets rendered as copyright symbol happens on both preview and post, and when you switch between fast reply and full editor
  20. John - of course you are right that question said "Not the arch curve but the straight line between them." Even now I tend to read the question too quickly - but I still struggle to see how it could easily be done otherwise. The Taylor Series would be accurate to 1 in 10^9 by the second term because of the smallness of the angle. But even restricting to two terms cubing pi/80 (to 7 dp or more) is an awful job. There has to be a trick that I am missing. I hope the OP posts the intended solution method
  21. Anyone have any idea what sort of aircraft is in the sky at 1:35 of the video. The pilot must have had a pretty spectacular and scary view (unless I have my perspectives wrong)
  22. Skaff - I am not fretting, but thanks for your concern. R, SR, and GR are also not probabilistic as your last comment implies (unless perhaps at some arcane depth I have not reached).
  23. Relativity predated M&M by about 300 years. The opposite of objectivity is subjectivity - which means that the law and even the information are dependent on the individual being measured. velocities being relative doesn't mean that objectivity is lost merely that observations must be understood in a certain frame of reference; as these FORs and the calculations used with them are easily defined and universally agreeable then there is absolutely no loss of objectivity. The same applies to the transformations required to deal with coordinate systems in non-flat space.
  24. Not massively familiar with him - but the fact that Immanuel Kant, Adam Smith, Charles Darwin, Jeremy Bentham, and later Karl Popper thought of him as a great and central influence shows the importance of his work. I used this resource far too much in the past - you might find it interesting http://www.iep.utm.edu/humereli/
  25. Relativity doesn't dismiss objectivity - quite the opposite in fact. AJB called it the demand that "the physics should not depend on the details of how you chose to present it" - which sums up well the idea that it dismisses subjectivity and local variations.
