On Wavefunction Collapse, the Einstein-Poldolsky-Rosen Paradox and Measurement in Quantum Mechanics and Field Theory
Stuart Samuel
We first consider the Einstein-Podolsky-Rosen (EPR) paradox for the system of two particles with spin 1/2 with entangled spins in first-quantized quantum mechanics (QM). If measure…
Twisted Spin in Quantum Mechanics
Stuart Samuel
In quantum mechanics, it is often thought that the spin of an object points in a fixed direction at any point in time. For example, after selecting the z-direction as the axis of q…
Comments on an Expanding Universe
Stuart Samuel
Various results are obtained for a Friedmann-Robertson-Walker cosmology. We derive an exact equation that determines Hubble's law, clarify issues concerning the speeds of faraway o…
Characterization of a Branch of the Phylogenetic Tree
Stuart Samuel, Gezhi Weng
We use a combination of analytic models and computer simulations to gain insight into the dynamics of evolution. Our results suggest that certain interesting phenomena should event…
On the Speed of Gravity and the Jupiter/Quasar Measurement
Stuart Samuel
I present the theory and analysis behind the experiment by Fomalont and Kopeikin involving Jupiter and quasar J0842+1845 that purported to measure the speed of gravity. The computa…
On the Speed of Gravity and the Corrections to the Shapiro Time Delay
Stuart Samuel
Using a relatively simple method, I compute the v/c correction to the gravitational time delay for light passing by a massive object moving with speed v. It turns out that the v/c…
