• The Ring of Truth

    Savas Dimopoulos:Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision…

  • Euler’s Konigsberg’s Bridges Problem

    “Liesez Euler, Liesez Euler, c’est notre maître à tous”(“Read Euler, read Euler, he is our master in everything”) – Laplace I should say here that the post by Guest post: Marni D. Sheppeard, “Is Category Theory Useful ?” over at A Quantum Diaries Survivor, continues to invoke my minds journey into the abstract spaces of…

  • Blackhole evaporation: What’s New From the Subatomic-Sized Holes ?

    …the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein See What is Cerenkov Radiation? We are being “politically correct” (a sociological observation) when we change the wording of the “microstate blackhole production” to “Sub Atomic Sized Holes?” To…

  • Heralded from the 21st Century: String Theory

    I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality.” from Flatland, by E. A. Abbott It is sometimes important to know what race of rebels had been raised to realize that…

  • It’s a Penquin?

    The jump from conventional field theories of point-like objects to a theory of one-dimensional objects has striking implications. The vibration spectrum of the string contains a massless spin-2 particle: the graviton. Its long wavelength interactions are described by Einstein’s theory of General Relativity. Thus General Relativity may be viewed as a prediction of string theory!…

  • Where are my keys?

    “Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality.” from Flatland, by E. A. Abbott The Extra-Dimensions? So you…

  • Finiteness of String Theory and Mandelstam

    It might be that the laws change absolutely with time; that gravity for instance varies with time and that this inverse square law has a strength which depends on how long it is since the beginning of time. In other words, it’s possible that in the future we’ll have more understanding of everything and physics…

  • Graviton in a Can?

    After you consume “graviton in a can,” you might never be the same? Brane thinking may then dominate your every view of the world. Then, it will all make sense? Imagine while we peer deeper into the subject of the “perfect fluid/soup” we find that certain aspects of the reductionist work done, has indeed lead…

  • Gravity and Electromagnetism?

    “Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality.” from Flatland, by E. A. Abbott Oskar Klein and Theodor…

  • Lisa Randall on Xtra Dimensions

    In physics, Randall-Sundrum models imagine that the real world is a higher-dimensional Universe described by warped geometry. More concretely, our Universe is a five-dimensional anti de Sitter space and the elementary particles except for the graviton are localized on a (3 + 1)-dimensional brane or branes. The models were proposed in 1999 by Lisa Randall…

  • Back to the Beginning of Time

    While some of us who had been engaged in a little prehistory examination of earliest QGP states as glast determination of high energy photons, the question, “to Be or not to be,” how could we not ask what Professor Susskind offered up for examination under the title, “the elephant and the event horizon?” What happens…
