"In Physics in Mind, eminent biophysicist Werner R. Loewenstein seeks answers to these perplexing questions in the mechanisms of physics. Bringing information theory---the idea that all information can be quantified and encoded in bits---to bear on recent advances in the neurosciences, Loewenstein reveals inside the brain a web of immense computational power capable of rendering a coherent representation of the world outside. He guides us on an exhilarating journey along the sensory data stream of the brain---the stream that nurses our cognitions---and we see how the vast amounts of information coming in from the world outside get processed by the web, how its neurons gradually extract meaning from this hodgepodge, and how they arrive at a coherent picture of the world"--
