那些撼世的言语

Tony Bell 的这番话几乎让我泪流满面：

"My long-term scientific goal is to try to work out how the brain
learns (self-organises). This took me in directions of Information
Theory and probability theory for neural networks. This provides a
hopelessly crude and impoverished model (called redundancy reduction)
of what the brain does and how it lives in its world. Unfortunately,
it's the best we have at the moment. We have to do some new
mathematics before we reach self-organisational principles that will
apply to the physical substrate of the brain, which is molecular: ion
channels, enzyme complexes, gene expression networks. We have to think
about dynamics, loops, open systems, how open dynamical systems can
encode and effect the spatio-temporal trajectories of their perturbing
inputs. "
