  • The Little Book of String Theory offers a short, accessible, and entertaining introduction to one of the most talked-about areas of physics today. String theory has been called the "theory of everything." It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory.
    Steve Gubser begins by explaining Einstein's famous equation E = mc2 , quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book.
    The Little Book of String Theory is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.

    We should mourn the loss of Dr. Gubser at such young age. Condolences to his family. It is a huge loss to the advancement of physics.

    Hello sir, you are my one of the ideal person. As I have read your book that is A little book of String Theory. I totally got impressed with that.

      Hey Adityadhar, maybe you should read a book on basic English grammar first, before reading about String Theory.."you are my one of the ideal person." hahahahhaa.. where did you learn English?

    Comment on your
    Book ‘The Little Book of String Theory’, Steven S Gubser.
    My name is
    Armaan. I am a 14 years old, Blackholes theorist, from India.
    Your book
    provides the reader with a crucial insight, into Quantum Physics and its
    relations with the large scale world. It describes beautifully, how the
    Universe must work. Even I myself cannot explain a cosmos, so complicated in
    all its aspects like Blackholes, without presuming the existence of extra
    dimensions. But I believe extra dimensions are not getting any bigger.
    In fact, in my
    quest for extra dimensions, we must follow the reverse. We must search
    complicated nuclei of atoms down way below, Quarks and Gluons for negative mass
    extra dimensions. When I tried to apply my theory to the cosmos, it required a
    different approach on my end to fit it in our current understanding of the Universe.
    So, I treated space as a dynamic fluid [not the literal matter fluid, but a fluid
    of space-time] in which objects create whirlpools ,in which, other smaller objects get caught.
    Blackholes are
    these huge whirlpools which lead us to another higher dimensional parallel
    universe, and I believe the cosmos is just this small corner, in a multiverse
    of universes, wherein Blackholes are the connections between two universes. I
    believe Einstein’s ideas seem to raise more questions, than they answer; for
    instance they predict a Blackhole but break down at the Centre of the Blackhole,
    they predict the big bang, but break down at the instant of the big bang. I
    believe the creation of a new universe is basically inflating a new cosmic
    backyard with a finite dimensional fluid and a Blackhole which is throwing the stuff of one universe
    into another, explains the only connection between the two universes.
    Where our universe came from?What existed before the point of creation?
    I believe space
    had a constant eternal charge or disturbance in the metric to the smoothness of
    space. This disturbance would lead to the accumulation of charge to form the
    first atom in the multiverse.
    String theory
    gave me a reason to think beyond, and if viewed, from the angle of my theory,
    it could provide the only missing piece, in the much awaited theory of
    everything.
    Time Dilation and extra Dimensions
    Are Blackholes and
    extra dimensions connected?
    I believe what a
    Blackholes does to an infalling object, is key to unlocking the secret of extra
    dimensions. The Blackhole stretches and spaghettifies the objects in such a way,
    that the objects are so focused, that the collapsed matter which they are made
    of , turns into higher dimensional
    universe and higher dimensional stars, which have, magnetic fields and
    properties that cannot be explained without the existence of extra dimensions. Understanding
    collapsed higher dimensions and the quantum mechanical world at large will help
    us understand magnetars and how multiverses change the behavior of time, due to
    gravitational influence [as my picture of time is a wave] which is molded by
    gravitational whirlpools in the fluid like nature of space. This way of looking
    at things could explain the complexity of our cosmos, and also explain how
    there need not be a definite beginning, to the multiverse at large. [According
    to me there was a forever existing charge, which had a tiny irregularity, which
    led to the formation of the first hydrogen atom].
    I never understood
    how something could ever be the smallest thing and never understood the concept
    of a zero dimensional point.
    I found your
    book very fascinating. I hope my opinions through this paper will throw a
    different perspective that help us in
    our quest towards better understanding of the multiverse. Hoping to hear from you.

    Thanks Steve. You just sold another book. I'm studying String Theory using Susskinds lecture videos and some other relaible sources. Its going a little slow but productive. I'm a 44 year old Quality Manager working in the aerospace industry "by day" and string theory student "by night". I've been looking for some applied material, and I believe I've found it! Thanks again! If you have any advise for me please feel free to email me.

      Hello there. I, too, am very interested in learning more in depth stuff, though I have a long way to go before even considering a course in string theory as I am a 15 year old high school student, could you recommend any reliable sources that would aid me in improving my mathematical skills? I am currently studying basic calculus (differentiation, integration, kinematics, trigonometry etc.) Thanks.

      Best way to develop your skills would be to actually enroll in a physics course after high school. First learn all the basics like Classical mechanics (including Lagrangian and Hamiltonian formalism), Electromagnetism, Statistical mechanics, Mathematical physics, etc. For mathematical physics, there are a lot books out there that are good. But personally I find Mary L. Boas's book the simplest and most approachable. Once you have enough confidence, go for Arfken's book, It's a little tough compared to Boas, but a really good book.

    Don't use a Duracell battery, you'll get about 30 seconds' use out of it, just saying...there's good reason Mercedes and BMW only allow Interstate batteries under warranty.
    Ooo, car battery amd blow torch. This ought to be fun. :)
    Too bad he fell to his death climbing. Is back-up rope or back-ups in general not a thing in climbing? JC, not to be mean or rude. Or is it more like motorcycling, the thrill is SO great that it's worth a greatly added risk and while death is now a higher factor, it's such an amazing way to experience the world, I think everyone should tour the country that way. It certainly makes you a better driver when your habit is to turn around and look and not rely on mirrors.
    And that, realistically, there's no way to make it safe? That you know full well eminent death might be part of the deal in a way you never think about irl. Maybe that makes you feel more alive and appreciative? It's also much more difficult than a car over long distances, so it becomes about endurance.
    At 2:30 telling his quote, the eyebrow wiggle, I'm betting, was a huge clue to the man he was. Lol.
