... as a quantum field theory on the (1+1) dimensional worldsheet of the string, S = d σ Lstring . There exist many such quantum field theories and so there exist many string theories. Further, for some string theories the strings themselves arise from wrapped higher-dimensional objects and hence can ha ...

Reductionism and Emergence: Implications for the Science/theology
... measure proper time along fundamental world lines: thereby determine the transition surfaces (“the present”) as time evolves along preferred fundamental world lines. This is not globally coordinated by some non-local mechanism: rather it happens locally everywhere So change happens on preferred surf ...

Emergence in Holographic Scenarios for Gravity - Philsci
... Accordingly, there is a finite number of degrees of freedom in a black hole system. ’t Hooft carried the argument one step further by pointing out that if a spherical volume V is bounded by a surface A, the total number of possible states and the entropy inside A are maximized if the volume contain ...

Another Philosopher Looks at Quantum Mechanics - SAS
... My own conclusion from studying a large number of cases where theory is brought to bear on real phenomena is that neither quantum nor classical theories are sufficient on their own for providing accurate descriptions of the phenomena in their domain. Some situations require quantum descriptions, so ...

An introduction to rigorous formulations of quantum field theory
... In fact, if we had a true measure, the above expression would be well-defined. (See Section 3.5 for an introduction to this topic.) You might call an element of this space a wavefunctional, in analogy with the wavefunction of non-relativistic quantum mechanics. In ordinary quantum mechanics, an elem ...
