Fool’s Gold
Ludwig Boltzmann (1844-1906) In 1877 Boltzmann used statistical ideas to gain valuable insight into the meaning of entropy. He realized that entropy could be thought of as a measure of disorder, and that the second law of thermodynamics expressed the fact that disorder tends to increase. You have probably noticed this tendency in everyday life!…

Universal Error Correction in Quantum Computation
Physicists have succeeded in entangling five photons for the first time. Although four photons have been entangled before, five is the minimum number needed for universal error correction in quantum computation. Moreover, the same team has demonstrated a process called “open-destination teleportation” for the first time (Z Zhao et al. 2004 Nature 430 54). The…

Information in the Holographic Universe: A Holographic Spacetime
by Jacob D. Bekenstein TWO UNIVERSES of different dimension and obeying disparate physical laws are rendered completely equivalent by the holographic principle. Theorists have demonstrated this principle mathematically for a specific type of five-dimensional spacetime (“anti–de Sitter”) and its four-dimensional boundary. In effect, the 5-D universe is recorded like a hologram on the 4-D surface…

Quantum Gravity Models
PLato saids,”Look to the perfection of the heavens for truth,” while Aristotle saids “look around you at what is if you would know the truth” Quantum Gravity I guess we have a choice here? Between the models of what would be percieved of, as higher dimensional realms, in terms of abstract model building, that is…

Quantum Harmonic Oscillator
Let us see how these great physicists used harmonic oscillators to establish beachheads to new physics. Albert Einstein used harmonic oscillators to understand specific heats of solids and found that energy levels are quantized. This formed one of the key bridges between classical and quantum mechanics. Werner Heisenberg and Erwin Schrödinger formulated quantum mechanics. The…
