Several philosophical problems arising from the physics of consciousness, including identity, duplication, teleportation, simulation, self-location, and the Boltzmann Brain problem, hinge on one of the most deeply held but unnecessary convictions of physicalism: the assumption that brain states and their corresponding conscious states can in principle be copied. In this paper I will argue against this assumption by attempting to prove the Unique History Theorem, which states, essentially, that conscious correlations to underlying quantum mechanical measurement events must increase with time and that every conscious state uniquely determines its history from an earlier conscious state.
This is the story of the Global Consciousness Project, a unique 20-year scientific collaboration of researchers recording the effects of mass consciousness in response to major global events. Its findings are consistent with the wisdom traditions of many cultures and speak of humanity’s unity and deep connections through love, compassion, and the creative impulse.
In order to dive deeper into an exciting topic, we’re mixing up the format. Over the next three days, we’ll spend the next three episodes exploring an incredible application of seemingly purely-abstract mathematics: how algebraic topology can help us decode the connections among neurons in our brains, to help us understand their function.
Last episode we saw that your neural network can be modeled as a graph, which — we’ll show in this episode — can be viewed as a higher-dimensional simplicial complex. So… what is a simplicial complex??
This work was the first sustained philosophical study of psychic phenomena to follow C.D. Broad’s LECTURES ON PSYCHICAL RESEARCH, written nearly twenty years earlier. The author clearly defines the categories of psychic phenomena, surveys the most compelling experimental data, and traces their implications for the philosophy of science and the philosophy of mind. He considers carefully the abstract presuppositions underlying leading theories of psychic phenomena, and he offers bold criticisms of both mechanistic analyses of communication and psychophysical identity theories.
Science really is everywhere. On this episode of StarTalk Radio, we bring you the first part of StarTalk at BAM – Science is Everywhere. Back in March, we had a great time at the Brooklyn Academy of Music highlighting the shows under the StarTalk Podcast Network banner. In Part 1, you’ll hear StarTalk Radio and StarTalk All-Stars. To start, Neil deGrasse Tyson is joined by comic co-host Chuck Nice and theoretical physicist and author Brian Greene to discuss the early universe. You’ll hear about the “Cosmic Dark Ages” and what we know about the first stars born in the universe. Read More
“We must consider this question, can machines think?” Alan Turing asked that question many years ago, but these days that question is taking on a whole new dimension. On this episode of StarTalk Radio, Neil deGrasse Tyson, comic co-host Chuck Nice, and neuroscientist Gary Marcus answer fan-submitted Cosmic Queries on the intersection of minds and machines. You’ll learn what distinguishes the human mind from the minds of other mammals. Explore the mysteries of memory and the future of memory storage. You’ll also learn how humans have “context addressable memory” whereas computers have “location addressable memory.” Find out more about human Read More
