  1. Thanks :¬) Now I Understand I had the assumption that the eye mesured the freqency of each photon of light entering it. I now know that there are 3 types of colour receptors in out eyes, red, green and blue. Which is why we get duped by purple and can't tell orange (red + yello) from orange.
  2. X Rays, UVLight, , Infer Red, Microwaves Take a sheet of paper and shine red light onto it, then shine green light onto the same place, the result is yello light. The elecromagnetic frequency for yello light is half way between red and green If instead you shine red and blue light you get purple, however green is half way in turms of frequency between red and blue, not purple. To me this makes little sence? This got me wondering weather someone could tell the difrence (for example) between light at the frequency for yello and equal amounts of red and green light (also making yello).
  3. I supose a possible sensible course of action could be to create a list of things other than the arial to this device that resonates at 6.4MHz (to electromagnetic waves) If there are any? If it turned out bone pins did it would be a real showstopper. I hope and expect this however not to be the case. Maybe if it was they could just redisign those things.
  4. Do we say graverty is week because we compare it with other forces? A magnet can pick up a paperclip and win out againsed the force of the whole planet at lifting that paperclip up with magnatism (as the whole earth tries to pull it down with graverty and fails) So we think "wow magnatism is strong and graverty is not" However the magnet is a heavely optimised structure, wheras the earth is just a whole load of unopimised rock. A piece of a black hole may have a comparable force to a strong neodymium magnet of the same size. both are highly optimised one for a stong gravermetric force and one for stong magnetic force. Sorry, If im totaly wrong, Its just as I understand it at the moment.
  5. "Physics 10 - Lecture 10: Electricity and Magnetism II" shocked me at how simple the levatation at 51:15 was. Why don't we have more technoligy based on this? (sorry axidental doubble post)
  6. I too found that episode fasinating, I am somone who did not know that stuff before, maybe this thread should be stickied.

    Why gravitons?

    ty, what it should have read was. "There is no way we fully understand or can manipulate graverty in the same way we understand and can manipulate other forces such as magnatetic fields's or electric fields. any advances are a good thing :¬)" also read at least the first few lines of this http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html

    Why gravitons?

    there is no way we fully understand or can manipulate graverty in the same was we understand and can manipulate magnatism or static electrisity, any advances are a good thing :¬)
  9. http://news.bbc.co.uk/1/hi/technology/6129460.stm Sound Likely? or not?
  10. Thease are the "Physics for Future Presidents" Lectures, streamed over google video from the university of california. http://video.google.co.uk/videosearch?q=Physics+for+Future+Presidents Go find one that intrests you, they are really good :¬)
  11. lol, I can't really do any more, I don't know how to go about building all the mecanism needed. lol
  12. It tends to be based verry much on regon, I know there are a lot of religous people about but in some places or types of socity they will outnumber the rest of us and in some places it is the other way around. It is good of you not to go to church if you no longer bellive.
  13. evenly spaced, there is verry little margin for anything else with how I have it set up, if they are to close they all slide towards each other and stick together, to far apart and there is not enough effect to keep the wave going.
  14. Iv'e been trying to build it today, the magnets I'm using are strong enough to spin around and face north\south if u put them down on the table on there own, however the magnet quality is not representative of the quality of the rest of the equipment. Im using blue tack and milk bottle tops and stuff At the moment I have the problem that I can't get all 5 in the line witout some of the middle ones pulling towards each other. If I add something in between them to maintain the corect spacing it creates to much friction, or they flip un into the air and over the top of the thing ect... However, despite this I got 4 in a line to work and the result is verry unexpected, they actually speed up as it goes along the line, the first turns about half way round before the second does and it continues almost like a wave along the line but each one being faster than the previous.
  15. Myself, I don't do drugs (Including beer). but It's intresting hearing about thease things. There is a lot we still don't know about dreams.
  16. /applaud
  17. It wont work at least the way I intended it with a circle, it needs one fixed and one free end, circles have no end's only a verry long middle. Also, friction is not a good thing.
  18. No Exactly, otherwise you would have to pull all the magnets round half a turn in turning the first one. Now imagine that it is not a circle but a line, where the first magnet (the one we rotated at the start) is fixed in place but the last magnet in the line is not, after all that rotating stated in the above quote has happened the second third ect... will continue to turn a bit more untill they are all lined up. eventually friction will stop this hapening after a line of a cirtain length, but that length will be verry long.
  19. Is there Time involved? A butterfly flapping its wings last week causes a hurricane or whatever to happen or not hapen today, as chaos effect makes all sorts of stuff pan out difrently over time even if there is only the smallest of changes?
  20. You don't have to turn all the magnets by turning the first one, in fact there is only the resistance of the first few as the magnets that are sevral away have much less effect than the once verry close, once the first one is then locked into place all the magnets will end up turning half a turn. The first one will require almost the same energy to turn if there is just 20 than if there is 100, because 80 of the 100 will have almost no effect on the first one, and once the first is locked into place the others will allighn themselves at a half turn from what they are. Then when they are all facing the other way the cycle is ready to start again by only turning the first one. Somone else asked For which the answer was simerlar Friction is too great with week bar magnets on a table Stronger and possibly cylidrical magnets on something that can rotate freely and easely is needed and to which the answer is Sorry that soo long, but I wanted to put a lot of explonation in it, please reply again Severian
  21. Yes However big X is you can always make N bigger with more magnets, However X is an almost fixed value after N becomes bigger than a cirtain amount We have also decided we may need logeritmic spacing between the magnets, although by my observations we don't I was only using a few magnets again Im quoteing from one of teslamotors1's posts, as I guess you may not wan't to read though the pages of posts on the other forum to get at all the progress made so far
  22. wow, that does sound unlikely externet, would be amazing if it where true, maybe there is a google video of it, google video often has TV programs and such

    Is this OU?

    This is a quote of somone on another forums explaning to the other forum members what I ment when I was trying to discribe an anomile I encountered while playing with magnets The orriganal post is here http://www.steorn.net/forum/comments.php?DiscussionID=17702&page=1#Comment_260721 Please can I have some feedback
  24. Sonar = Radar in water Radar = way to big to be practical "echo transponders"? I can't find much info online about them if its an "audio camra" that works like a bat does it I want one.
  25. Bats have a clever systems built into them to help them see in the dark using sound I'm assuming most of you know roughly how it works http://science.howstuffworks.com/bat2.htm http://en.wikipedia.org/wiki/Bat However seeing in sound instead of light means they see in a completely different way, for example among other things the objects density and surface qualities of the objects like is it rough or furry or smooth or at an angle would have a large effect on how sound is deflected by the object in a very different way to light, also sources of sound are difrent than those of light. loud sound seems travels though walls for example to annoy the nabours when light would probably not do. so, why can't we make an artificial bat? I suspect it is because we can't get microphones that are directional enough or that we cant make high pitched and loud enough noise with the right delays for it to work. maybe its been done before and I don't know, or its been done and is impracticly big\expensive.
