Russell’s Paradox and Possible Solutions
The origins of set theory can be traced back to a Bohemian priest, Bernhard Bolzano (1781-1848), who was a professor of religion at the University of Prague.
An Introduction to Current Theories of Consciousness
(Crosspost from my blog) • • There are few academic lists of theories of consciousness (Doerig 2020) as well as some good blog post series about specific ideas (shout out to SelfAwarePatterns), but…
Consciousness, Cognition and the Neuronal Cytoskeleton – A New Paradigm Needed in Neuroscience
Viewing the brain as a complex computer of simple neurons is insufficient to explain consciousness and cognition. A new paradigm is needed that considers the brain as a scale-invariant hierarchy, with quantum and classical processes occurring in cytoskeletal microtubules inside neurons. Evidence shows that microtubules regulate specific firings of axonal branches and modulate membrane and synaptic activities. This new paradigm suggests that information processing for cognitive and conscious brain functions occurs in microtubules and involves both top-down and bottom-up regulation within the brain hierarchy. The precise mechanisms of consciousness may be most likely to reveal themselves in Layer V cortical pyramidal neurons, which have a large collection of mixed polarity microtubule networks.
Bekenstein bound
The Bekenstein bound is an upper limit on the entropy or information that can be contained within a given finite region of space with a finite amount of energy. It implies that the information of a physical system must be finite if the region of space and energy are finite. The bound was derived from arguments involving black holes and has implications for thermodynamics and general relativity. It can be proven in the framework of quantum field theory and has applications in various fields, such as black hole thermodynamics and the study of human brains.
A New Physics Theory of Life | Quanta Magazine
According to physicist Jeremy England, the origin and evolution of life can be explained by the fundamental laws of nature. He proposes that living things are better at capturing and dissipating energy from their environment compared to inanimate objects. England has derived a mathematical formula based on established physics that explains this capacity. His theory, which underlies Darwin's theory of evolution, has sparked controversy among his colleagues. While some see it as a potential breakthrough, others find it speculative. England's idea is based on the second law of thermodynamics and the process of dissipating energy. He argues that self-replication and structural organization are mechanisms by which systems increase their ability to dissipate energy. His theory may have implications for understanding the formation of patterned structures in nature.
