... BH suggests that mind and matter find a common origin in Bohm's implicate order. The implicate order is "beyond space-time and takes process as primary". What is "process"? Does it presuppose "time"? Hiley opens with a great quote from Freeman Dyson's "Disturbing the Universe" that consciousness is ...

Lecture 11 Identical particles
... Until now, our focus has largely been on the study of quantum mechanics of individual particles. However, most physical systems involve interaction of many (ca. 1023 !) particles, e.g. electrons in a solid, atoms in a gas, etc. In classical mechanics, particles are always distinguishable – at least ...

The Emergence of Classical Dynamics in a Quantum World

This means that, if the initial states of two identical copies of a system (for example, particle positions and momenta) differ by some tiny amount, those differences magnify with time at an exponential rate. As a result, in a very short tim ...

Recently, experimentalists have successfully cooled the macroscopic oscillator to its ground state using optomechanical interaction [2, 3] and unveiled the hitherto elusive quantum radiation pressure shot noise [4]. These remarkabl ...
