    Michio Kaku: Physics of Invisibility - YouTube

    HowStuffWorks Videos "Sci Fi Science: Invisibility Cloak"

    Small-Scale Invisibility Cloaks | Dr. Kaku's Universe | Big Think

    -----------------------------------------------------------------------------------------------
    A text from Small-Scale Invisibility Cloaks | Dr. Kaku's Universe | Big Think :
    " For generations, the topic of invisibility has been of great interest. Although it was once dismissed as science fiction, it has now become reality on a small scale. Physics textbooks around the world must be rewritten and scientists must admit that they were wrong."

    This is an open discussion which means let people speak themselves what they want to on this topic ,but I want to notify that Dr.Michio Kaku is a reputed respected Theoratical Physicst and reputed famous personality who also wrote Physics books with Stephan Hawking.Michio is one of the founders of recent versions of string theories.

    Aman, please don't post links without some comments on the topics in those links. This is a discussion forum, not a suite of reference pages. So what do you want to say about invisibility? Do you think it has applications? Do you think its use should be controlled? etc

    I might add that Dr Kaku has forfeited much of his respect and credibility by going way off the deep and, and sensationalizing borderline science on TV.

    I am here to learn,what's going on really.I saw few more videos elaborating more on Research in Microwave invisibility especially with Duke University.This has been till now not in my field of research but I am really excited to know about it.Not only me,people who have interest can learn reality from this thread and can discuss about the topic in this thread.

    It has been an active area of research for several years. It is not true invisibility. It works for small objects at one specific electromagnetic frequency that the cloak is designed for.

    Yes,but how exactly they do it is bit confusions.Can you throw some light on it?
    Why we need one specific Frequency?

    I should think that is the last thing you want to do if you are aiming for invisibility.

    Because the metamaterials used to deflect the "light" (by that I mean whatever frequency in the electromagnetic spectrum, be it visible, microwaves, etc) have specific spacing that only deflects that one prequency perfectly. All other frequencies are not deflected perfectly, so the object can be "seen'.

    Thanks!So why this particular frequency is only deflected?why not other fequencies?

    Textbooks are regularly updated with new science. What exactly must scientists admit they were wrong about? Which scientists? Do you have a reference to a published scientific paper that says that this sort of thing is impossible?

    Also, you are misusing the word "pseudoscience". I'm not quite sure what you mean by it, but pseudoscience is when someone says something like: "gravity is caused by magnetism's chronosynclastic effects on the cosmic infundibulum" or "I can prove that relativity is wrong because obviously time is motion and motion is time. QED" or "I don't need evidence or math, just logic and common sense".

    In other words, the use of meaningless scientific-sounding jargon, empty arguments and the complete lack of evidence.

    Michio's website say this things about rewriting textbooks,I did not said about textbooks myself.

    May be duke University should have research papers describing how Metamaterials actually works,if what Michio says is actually right .

    Since Michio is a well respected physicist and colleque of the great,Stephan hawking,I cannot tell directly that whatever Michio says is surely incorrect.

    I am just seeing Duke Iniversity website for getting the related Research document.

    I am here to get to know about the recent research about Invisibility cloaks.

    The papers are published in the peer reviewed journals Science, Nature, and Nature Materials. I've read several.
    That's where things like this get published.

    That's why I know so much about the details

    I'm sure they have if they have been researching this area.

    Oh, and they have:
    David R. Smith's Metamaterials Site: About Metamaterials
    Welcome to Center For And Integrated Plasmonics

    (By the way, Kaku didn't invent any of this stuff. He just loves to talk and speculate about what might happen in the future. Which is great, but I would take some of what he says with a pinch of salt.)

    I am here to get to know about the recent research about Invisibility cloaks.
    Unfortunately, most of the articles I have read are not available online.

    Thanks!

    I heard that Kaku has collabrated in String theories with Stephan hawking and some other theorists and contributed to string theory.

    I don't know much about his contribution to string theory.He is theoratical physicst in Quantum Physics and not an inventor.He also has co-authored books with Physicist and string Theorist Jennifer Thomson which I have.

    But that doesn't mean everything he says is true or valuable. He is only human. He is just as capable of being wrong as anyone else.

    I know,I am not sure what he is telling is true but I only initiated the thread with a text /paragraph extract from his website,http://bigthink.com/ideas/19268
    so that readers can explore more deeply into the subject.

    Thanks for the websites on Metamaterials (Duke university) but the info available is limited on the website as of now.I am surfing though the publications on the website but only abstracts mainly can be found which is not worthy to see.

    I heard that you need a membership for accessing online Science Journals,is it required to have a membership for Journals,I mean are journals not freely accessible ?
