Inventor Andrew Knight explains how the laws of physics may answer some of the hardest problems in the philosophy of science, such as the nature of consciousness, whether humans possess free will, and what causes the arrow of time.
Further to my blog post
about finally getting published, my first
physics publication posted a couple of days ago in the Foundations of
Physics regarding a common misperception in quantum mechanics.
Also, I made the following presentation ("Refuting Algorithmic Consciousness: Why Mind Uploading and Conscious Computers are Impossible") in a concurrent session at the 2020 Science of Consciousness
conference on Tuesday.
post, I pointed out that even though the phrase "copy the brain" occurs all over the
Internet, my post might be the first in history to state that it is "impossible
to copy the brain," an illuminating observation about the pervasive assumption that brains can be copied.
The same is true of these phrases, of which a Google
search yields only my own works:
"Schrodinger's Cat is impossible"
"Schrodinger's Cat is not possible" "Wigner's Friend is impossible"
"Wigner's Friend is not possible" "Macroscopic quantum superpositions are
"Macroscopic quantum superpositions are not possible"
"Macroscopic superpositions are impossible"
"Macroscopic superpositions are not possible"
Obviously, I’m not the first person to doubt that they
are possible, but the fact that the above phrases yield nothing (until you
remove "not possible" or "impossible," yielding thousands of results) should tell us
something. It is practically established
doctrine in the philosophy and foundations of physics that the Schrodinger’s
Cat and Wigner’s Friend thought experiments, along with the ability to measure a macroscopic system in quantum superposition, are possible in principle.
The thing is – they’re not.
Here is my newest YouTube video, entitled “Why
Macroscopic Quantum Superpositions are Impossible in Principle.”The concepts are elaborated in preprints here and here, with a more comprehensive explanation of (my current understanding of) quantum mechanics in this blog post.
