  1. Now this bit is totally tongue in cheek.

     

    imatfaal I must protest! The land area figures you quotes were for all American States and Territories, but the Australian figures were for our two main island only. If you include all Australian States and Territories the figure is 13,588,524 square km, beating Europe by over 3 million square km. :P You forgot to add in the 5,896,500 sqare km of the "Australian Antarctic Territory". :P It might only have 1,000 people and be the arse end of the planet, but it still counts. :D

     

    Now if we'd ever managed to get this ad campaign off the blocks, you could add New Zealand by now as well. :D

     

     

    Tongue firmly in cheek as well ... but if you include British Antarctic Territories and Queen Maude Land (Norway) then we get another 4.2 mill - putting us back in front.

     

    Love the ads - trouble is if we made ads like that in the UK people would think they were serious

  2. In non-scientific papers one can easily do without any references / citations of old work by the choice of subject or perspective, but avoiding modern work is very dangerous because it lays the paper open for criticism in terms of usefulness to today's academic community (as ajb said above) and perhaps betrays a poor literature review and understanding of current thinking

  3. Hate to rain on both your parades about which is bigger - but according to wikipedia the fount of all knowledge the areas are as follows:

    1. Europe 10.18*10^6 km^2

    2. America 9.83*10^6 km^2

    3. Australia 8.47*1-0^6 km^2

     

    In population terms

     

    1. Europe 731*10^6

    2. America 308*10^6

    3. Australia 32*10^6

     

    Frankly those figures are a bit screwy as well cos they include bits in Europe that don't feel very European (and North America as a continent is huge) Back on the point (before Dragon calls me a jerk again!) - those broad brush strokes you talk about are indeed dangerous, but they are hard to avoid when the images we are fed of other countries are selected by their extreme nature. We regularly read/hear news stories about school boards in the States acting in a reactionary manner - but of course, we never hear about the vast majority who are rational and progressive. When I worked in New York the minor news stories I read about Europe painted a picture that I didn't recognize at all - and I sure that the same applies in reverse. That said, it still seems whilst Australia, 'old Europe', and many other countries are moving away from religious involvement in education and government in general; that America, the accession States of the EU, and much of the Islamic world is moving towards greater cohesion between state and religion.

  4. Poww - glad to help. Once I saw 1.414 (square root of two jumps out at you) and 14.14 (ie ten times the sqrt2) then the route to the answer was pretty clear. And I guess you have already sent me praise (many thanks) by hitting the green plus badge at the bottom right hand corner of my posts.

  5. Hello Poww - no you have it the wrong way around. What I said was take the square of each of number - so for x=4 y =4 you would take 5.656854 (or whatever number of decimals you have) and square it to give 32. Now try and figure a connection between 4, 4 and 32 - now see if this connection will work for another cell.

     

    BTW we normally call x the variable that goes across the page and y the vertical one.

  6. I propose scalar-motion, it can be expressed with a simple number the Hubble constant H0 and has units of inverse time. It doesn't have any special direction unlike vectorial motion. It can also be negative and that is gravity.

     

     

     

    But expansion increases with distance so its inverse should be related to the reciprocal of distance; however gravity is related to the reciprocal of the square of distance.

     

     

    edit

    Just noticed you said negative not inverse - but same argument applies.

  7. Cooper pairs are when two fermions "act as one" to form a bosonic quasi-particle. This does not have to be two electrons. But yes, Cooper pairs are essential in standard superconductivity as well as the superfluidity of Helium 3.

     

    Ah - that makes sense. As a very speculative follow up:

    if you get massive photons in an electrical superconductor; do you, by analogy, get massive gluons in a colour superconductor?

  8. Not at all - the assumption is yours; to whit, that an explanation exists that is both valid and you can comprehend. Bell's inequality, whilst still argued over, goes a long way to confirming that classical theories cannot explain qm effects. The second reason for my contention is that, if a simple and true heuristic existed I wouldn't be trying to get my head around grassmann variables; ie the educators of the world would seize upon it with great sighs of relief.

  9. Many of the stories in the UK press about non-religious intolerance for religious holidays (or one religions intolerances for anothers holidays) are just make believe. At least one newspaper every year will run a story about a council banning christmas - or at least calling the holiday something else normally Wintertide- and on closer inspection they are just false. Anyone offended by someone wishing them happiness and good cheer by saying Merry Christmas is, frankly, a bit weird. I am a fully-signed up atheist - yet in a twelve month period I have been to Christmas parties (with carol singing ), diwali celebrations, joined in an eid feast, and was invited to a sri lankan buddhist celebrations host by my catholic sri lankan neighbour

     

    PS David Cameron say multi-culturalism has failed - to be honest in London it seems to be doing just great.

  10. Lemur - the fact is that with modern physics there is a choice between "something ... designed and desired to be understandable" which tallies with our innate preconceptions of the way the world works and theories that actually describe experimental reality and can claim to be consistent with the facts. If you can get hold of it, have a read of the introduction to Leonard Susskind's The Black Hole War which looks, briefly but nicely, at this matter. Whilst I can see the points of the argument that claims an almost deliberate obfuscation, it is incorrect; there are no easy, accessible, and everyday routes through QM and most of modern physics.

  11. I think oldman was saying that the ratio of times of emission and the ratio of strengths of forces should be inversely proportional - rearrangement of that simple equation would give time for graviton emission in terms of the ratio of energies and the time of emission of a photon. This would be dimensionally correct - but I am really very unsure that there is any physics behind it

  12. I do a fair amount of academic reading on an exercise bike - either real book or kindle. When you get in the zone it is great; time flies, the exercise part loses any grim boringness, and the reading sinks in. But, when you cannot get into the correct frame of mind it becomes a form of torture; perceived passage of time slows to a crawl, nothing makes any sense, and thus it is tedious and unfulfilling. I now find that, if after 5 mins, it really isn't working I just switch on some tunes or play computer games; ie I give up! I can force myself to exercise and I can force myself to study, but I cannot force myself to do both at same time

    Are we talking about the same electron pairs? I'm talking about two electrons at the first energy state, but you seem to be talking about an electron and positron appearing out of the nothingness of space then annihilating each other and then trying to explain a medium using it.

    But also, isn't the energy released from that type of collision suppose to be very big? Why aren't there explosions everywhere when in the Hadron Collider one particle and its anti-particle release huge amounts of measurable energy when collided?

    Low energy annihilations will produce two gamma rays with 511 KeV. The lhc operates with particles at much higher energies - the lead nuclei will eventually have c 500 TeV so 511 KeV won't be a problem.

     

    PET scans work by detecting those two gamma rays that are given off when a positron annihilates with an electron in the body.

  14. Your assertion that gps in general are not fulfilling their duty of referral is baseless - certainly some gps are bad at their jobs (anyone care to suggest a profession that has no slackers?) but the vast majority of specialist referrals come from the family practitioner. What makes you think gps are discount medicine? They are not cheap and they are trained to the same standard as hospital physicians.

     

    You continue to contrast doctors and archaeologists - 3 year degree 3 year phd; and you are as well academically qualified as you can be; most medics in England finish taking exams in late twenties early thirties with their memberships - that's ten years training. I am also unsure that archaeologists continue to be reviewed theoughtout their working lives to ensure they have kept abreast of latest ideas. And if an archaeologist screws up , it will be in the very rarest case that they will be sued for multiple millions

     

     

    Take a look at the gains in life expectancy and disease survivability - they are pretty good, and getting better, Drs cannot take much of the credit for that, but they can takes great deal.
