  1. .... That's a very mathmatical/mathematical way of trying to decide . Should a weighting factor be introduced to describe patent importance ? Are these patents the work of the person ? , a lot of people don't realise that if they work for somebody , that person has a right to their work because they are being paid . .... .....what? Are you confused ?
  2. JohnB , I thought this image was a few centuries old but didn't know from exactly when . What I said is like what people say about other countries . If a historical figure could be transported to the future they would be amazed at what their country has become . How does Australia treat these people ? Are they busy tending to their lovely gardens and mansions from the profits of all the natural resources that their land has to offer the world ? Do they not have to worry about the tuition fees for UNI for the children ? Tell us JohnB , We are ignorant , life is not all Neighbours and Home and Away !
  3. Michel , Here is an image of Knowth , It has 18 smaller mounds surrounding it . I think that what you have circled is possibly an excavation of a smaller mound at Newgrange . The big mounds are huge , over 100m in diameter . If Stonehenge is an inner frame for a mound or building it has had stones and earth stripped away from it over the millenia . As for the YouTube machine , the past is full of weird and wonderful machines that have appeared and disappeared and long been forgotten . Did this person make his machine to specifically fit Stonehenge ?
  4. This is Newgrange . It is 5000 years old with some modifications to keep it alive as an entity . It is aligned with the midwinter sunrise . When the sun rises on midwinters day in the southeast it sends sunlight through the opening you can see at the lower part of the photo where the light shines down a passageway and onto a stone at the end of it . Is Stonehenge missing it's mound of muck ?
  5. What does religious mean ? If you define your religion to be the worshipping of the Sun God , which brings light to the earth or/and the worshipping of the Moon God , which lights up the darkness of the night sky then stonehenge could be an aid to tell you when your God / Gods will be around at the right time / times and in the right place / places to be worshipped . Physics therefore is your religion .
  6. From who's point of view is the answer to be given ? Maybe these two men would have a lot to say about bad things in Australia .

    Dejavu

    I started another thread called : Time ! Is time continuous ? In that thread I put the following , " It is a basic geometry statement that between any two points on a line there is another point on that line . But , between any two instants of time , is there another instant of time ? " When I did this I had one of those dejavu times . I describe it as the sense that what is being done at that instant has been done before , even possibly what is being done at that instant has previously been sensed possibly in a dream , but long forgotten .

    Tau versus Pi

    Is this actually an argument in science , not about whether it is obviously the best thing to do or obviously not , rather ' who ' decides what the standard correct interpretations will be ? So , who wants tau as 2*pi , IUPAC , AMS , Girl Guides of New Zealand ?

  13. Don't forget , to speculate or not to speculate ? , that is the question . Does everything he says hold true ? Cliff's conversation at the bar in which he talks about persia is edited and a laugh of the audience is heard , so , must cliff be discredited to us with a trick like this ? Also , Cliff at the end says that recent studies have shown a correllation between jetlag and baldness , in effect . Jet lag causes stress which a lot of people would think contributes to baldness . Again , is Cliff being discredited with a well placed laughing audience , thus reinforcing wrongly again that Cliff is unreliable ? Edit , a word omitted .
  14. Some people have a habit of declaring their conflict of interest , afterwards assuming the conflict of interest then disappears , because they have shown honesty in declaring their interest and they then are politically correct . It is possible to view this piece as a disguised advertisement and the attack on print media could be viewed as an attempt to sway the market towards the journal .
  15. There is also an issue of the validity of information from a particular time that may be long gone or not , as the case may be . When the information you are relying on was valid , is as important as who you are getting it from . This person knew how the journal operated at a particular time and again I will say that it could of course be a great journal , with great practices . I am sure the journal has changed since he left . How much ? What has changed ? Who are the new employees ? What is the new operating system on their computers ? Who are the old dogs trying to learn new tricks ? Do all fonts view correctly in Windows 7 ? Previous employees are always surprised at what they think the situation is in their former workplace , when it has actually slowly changed , like a snail who looks like it isn't going anywhere and you look around after fifteen minutes and it's gone !

    Tau versus Pi

    If people want to define , tau = 2 * pi , they can independently do that anytime they like currently . Tau has many uses and so does pi , ask the greeks !
  18. Moriel , I'll watch that video again ! ....................Later ....................... , So , an ex-employee ( supposed ) of the New Scientist is saying he thinks they are a good source as they are great at what they do , which he can personally vouch for because of inside knowledge ! Is it because they are great at what they do or because he , for whatever reason unimaginable , is saying so ? If they are a good source , it will of course be because they have a good process and intelligent people working for them , not forgetting readers who can also have an input in faultfinding . I am also saying that a source is not necessarily a good source just because they have good qualifications . I could ask twenty people to make me a cup of tea and a person with a degree in engineering is just as likely as a person without to put one sugar in it instead of the two I confirmed less than 5 seconds earlier . Everybody makes mistakes !
  19. Maybe the cat has a preference for all female offspring in a psychological sense , in that she may have taken the male offspring and dug a hole in the ground to bury them . This is complete speculation .
  20. I once heard photons being described as little pieces of energy . I suspect your statement is not being contrary to conservation of energy principles . Overall does this then mean that energy is changing from the form of kinetic energy due to motion of the electrons , into the form of photons ?
  21. The speed of light is a variable , under certain circumstances it is a constant . The constant in vacuum of 299 792 458 m/s is under certain circumstances . I'd love to trace the origin of light from a filament of a bulb and go through what material the light is travelling in and what it's speed is . It's great when you don't know how things work sometimes , it allows interesting questions to be asked . Like , Let's ask these physicists to give us an example of circumstances of how light could travel at 25 000 m/s , And , if they are not too busy , maybe another of 600 000 000 m/s . Is the speed of light in vacuum the fastest light can travel ?
  22. I did watch the video and I thought it was a good viewpoint . I think it would be interesting to read the minutes ( exact wording ) of the report . But I also thought that the reporter , even though he did declare that he had a previous interest in a scientific journal / magazine which was mentioned , was relying in part on the fact that he thought his use of said journal had legitimacy as a reliable source because he knew of the qualifications of the people concerned . They may have great knowledge and I am not specifically referring to them when I then say that just because a person has a high educational qualification doesn't necessarily mean they are a reliable source of information . Question those who ascert they know better and the two categories they will fall into will be those who are intellectually insulted and those who want you to do exactly what you are doing . Edit , slight spelling alteration .
  23. Somebody , who will remain nameless because the night is young and we all would like to get things done before the sun shines again in this part of Europe , previously said that light does not accelerate from below the sonic boom speed to above the sonic boom speed . Let's say I have a torch and soon after I press the electric switch to let the current flow the filament emits light . Is the light just being redirected from somewhere else where it is being stored ?
  24. Relying on information because the source has a 'good' education can be a source of errors also . People have a tendency not to question a source just because they think that source knows better . It is treated as being an intellectual insult to question some of the ' educated ' whereas to question others is exactly what they want you to do . What are my sources for the things I have just said . I don't have any !
  25. Jose , If you would like critique of your post , then I could start by saying you really do need to have a person to work with you on the english language . It will lead to a better understanding for all concerned of your invention .
