Clarifying the Tubulin bit/qubit - Defending the Penrose-Hameroff Orch OR Model (Quantum Biology)

Google Workshop on Quantum Biology Clarifying the tubulin bit/qubit - Defending the Penrose-Hameroff Orch OR Model of Quantum Computation in Microtubules Presented by Stuart Hameroff October 22, 2010 ABSTRACT The Penrose-Hameroff theory of orchestrated objective reduction (Orch OR) postulates quantum computation in microtubules inside brain neurons underlying consciousness. Specifically, Orch OR proposes that tubulin proteins comprising microtubule cylindrical lattices function as 'bits' -- switching between alternative states (eg of 1 or 0), as well as quantum bits or 'qubits' (existing transiently as quantum superposition of both 1 AND 0). Despite increasing evidence for functional quantum effects in warm biological systems, Orch OR has been recently criticized, eg in Phys Rev E by McKemmish et al (2009), who claim the nature and energetic requirements for switching of tubulin bits and qubits in microtubules make Orch OR biologically unfeasible and unsalvageable irrespective of any conceivable modification. Here we show that McKemmish et al misrepresent tubulin bit switching as proposed in Orch OR, and merely disprove their own misrepresentation. Specifically we address their allegations regarding regulation of tubulin switching by 1) van der Waals London forces, 2) GTP hydrolysis and 3) Fröhlich coherence, and show how they are wrong on all counts. We clarify certain aspects of tubulin with regard to potential bit/qubit function, and describe topological tubulin qubits ...

How to configure JBL Control Now speaker arrays

JBL ControlNow speakers can be mounted in more places than traditional speakers. For example they can be mounted flush in the corner of a room our in clusters of 2, 3, and even 4 speakers. They are the perfect solution for home theaters, outside the home, even in small retail stores or restaurants where coverage needs to come from only one or two speaker locations. Mount three off the corner of the house to provide stereo sound across the entire backyard, or use them as surround speakers in the back corner of the room.

Avenue Sound Dodge Viper

caraudiomag.com Part of the Pioneer Sound Build-Off competition. Built by Avenue Sound. Given the ultra compact cabin and limited options for speaker placement, the '00 Viper still sounded pretty decent, notwithstanding the forward-facing tweeters and the fact that your leg covered part of the door speakers! Still, who wouldn't want to drive this on a Sunday afternoon, know what we're sayin'?
