  1. Thank you for letting me know. I thought maybe i had gotten something wrong already. The effects of "Special Relativity" are hard enough to comprehend. In the example 'simple questions', SR effects are inter-twined with non-relativistic effects. It is an area which begs confusion. Hopefully this thread may clarify things a bit. No doubt i will say something completely stupid before that goal is achieved. So what.
  2. Thank you Luke. Nice to know someone else agrees with that point. An example may be helpful to others. I'll be posting one when i've finished checking it out for flaws that i might find. Do you care to elucidate?
  3. Correct. You could use a measuring stick/ruler in optional question.. 3) please state use of other. The velocity of reference frame 'B ref' relative to reference frame 'A ref' is 0.8c. The question is' date='... at what velocity will 'a' determine 'b' to be travelling at? I put it to you that if an object was traveling at 0.8c away from you. The velocity it would be seen to be traveling at would be somewhat slower. I base this proposition on the fact that the light image of the object takes an increasing longer time to reach you.[/indent']
  4. I guess these questions will seem rather trivial to experts in relativity. However i think the answers will be informative to those new to the subject. 'a' is an observer at a fixed point in a frame of reference 'A ref'. 'b' is an observer at a fixed point in a frame of reference 'B ref'. 'A ref' is deemed to be the stationary reference frame and 'B ref' the moving frame. The velocity of reference frame 'B ref' relative to reference frame 'A ref' is 0.8c. 'a' see's 'b' moving away from 'a'. At what velocity will 'a' determine 'b' to be travelling at by use of:- triangulation. red/blue shift please state use of other. Those mega-minds who never tire, may care to consider the same scenario with the following difference.... 'a' see's 'b' moving towards 'a'.
  5. How about testing and plotting the effectiveness of energy saving devices under a range of temperatures to simulate cold, moderate, and hot climates. I feel that this would be a worth while experiment, because there are many claims being made in the UK, that the use of low-energy bulbs and refrigerators will make a major impact on the number of power stations the nation uses. These ideas are being promoted by certain politicians who never lie. England tends to be cold in winter and warm in the summer so, it is my belief that the saving to the nation's total energy consumption will be considerably less than claimed, and that most of any reduction in electricity demand will manifest itself as an increase home gas consumption. If this kind of experiment is of interest, then i have one other experiment. The result of which may provide a means of reducing energy consumption. Send me a private message if your interested.
  6. Right. Look's like i've got some reading to do. Thank you for answer and link. Every time i find an answer to one question, a multiple of new ones come into existence.
  7. Thank you for such a clear well informed answer. By the same token, i wonder if i would be correct (in the light of current knowledge ) to believe that the same weightlessness might also be experienced at the center of a black hole, despite the apparent break down of physical laws, at or beyond the event horizon.
  8. I've been under the impression that gravity at the center of the earth cancels out. A sentient being in a habitable room there, would experience weightlessness. Can anybody assure me if that impression is correct, or explain why not? Thank you!
  9. I take this to mean that if the movement of cars over the bridge is the energy source causing movement, their miles/gallon kilometers/litre reduce below normal. Seem's right to me.
  10. Not sure in what context you consider it ignorant. So i will explain in more detail. All i am saying is, if you need heating in your house there is no saving of total energy using certain energy saving devices whilst it is on. I hope you will agree that if it takes a total of 1 kilowatt to heat a room to a certain temperature with a one hundred watt lamp off. It will still take a total of 1 kilo watt to heat it up to the same temperature with the light on. Without the light on, one kilowatt is provided to the room via a thermostaticaly controlled heater. When the light is on, the controlled heater will provide 900 watts to the room and the light bulb 100 watts. In a sense the light is cost free. The same goes for efficient fridges, unless you keep them outside, or are prepared to lower the temperature of your rooms the total house energy load remains the same. All the lamps in my house are hi efficiency, their working life is longer than a standard light bulb, but i have yet to have one last anything like five years. Their use has not noticebly reduced my total electricity consumption. I hope that clarifies my viewpoint.
  11. You might consider using Vacuum Insulation Panels for your window blinds and other cold spots. Just search google for plenty of info.
  12. I hope no one is going to suggest using energy efficient light bulbs or fridges as a means of saving energy in domestic situations. Such solutions remind me of the brown paper that we were advised to cover our windows with, as a defense against a nuclear strike. If you need heating in your house, use the brown paper now. It will save you more energy than using a low wattage light bulb will. My kitchen has been fitted out with energy saving devices. Now i'm cold, and need to fit a heater.
  13. Genuine open mindedness has virtues which i value highly. However it does have the disadvantage that a truly open minded person has weak beliefs and in extreme cases can become disfunctional. Many of today's accepted truths based on facts, will fall away, as new facts and way's of interpreting them emerge. Just as they have throughout history. There is for example a new Brown Hole theory that challenges current ideas about black holes without the problems of infinite gravity/pressure raised by the black hole model. As regards infinity in this universe, i suspect that every time nature is faced with an infinity there will be a transformation. How big is infininity? Ape of man say's .. God is still counting.
  14. I often wonder what effect the rise in sea levels will have on seismic activity, and the Earths wobble. As far as i am aware nobody is suggesting that all land based ice will be melted however there is enough land based ice to raise the sea level by 65 meters. Certainly some of the greenhouse gases will fallout as acid rain, but measurably not all. Some claim that many coral reefs are now dead or dying due to local acidification of their habitat. However it has been announced (via BBC World Service. Radio funded by UK foreign office) that according to the latest measurements the quantity of CO2 in the atmosphere is increasing. Not only is it increasing, the quantity that it is increasing by has accelerated in the last twenty years. Kyoto has made no difference to CO2 levels. I'm unsure of which thermal balance are you referring? Of the oceans, the air, the land, or the whole planet which is the topic of global warming. You do not explain where the energy goes to, and from there to where.
  15. The assignation of blame does not remove or aleviate the problem of global warming. Human action is part of the natural cycle, and it is about time we took responsibility for it. It is my belief that the immediate self interest of humans will prevent timely action. The latest data indicates that the melting of the poles is accelerating. So are the levels of CO2. To me that is a sign that it is already to late.
  16. There are people who still believe that global warming isn't happening. There are people who will never accept what is apparant and obvious to others. Ape numbers are like yeast to wine, nearly fermented.
  17. My favourite equation is the addition of velocities in accordance with the Lorentz Transforms of Albert Einstein s Special Relativity. To illustrate the transformational magic that occurs due to the constant speed of light c, i put a Java based relativity calculator on the web to celebrate the centenary of Special Relativity. The calculator use's geometry, to set and calculate all velocities and times. The geometry echoes the magic of the Lorentz Transforms, and provides an interesting way of understanding what is going on. Relativity Calculator. Interpretation.
  18. In reply to you said i. From http://en.wikipedia.org/wiki/Metaphysics Metaphysics (Greek words meta = after/beyond and physics = nature) is a branch of philosophy concerned with the study of "first principles" and "being" (ontology).
