The Phenomenon of Free Will
Ever since antiquity it has been a great mystery how the universe can follow definite laws while we as humans still often manage to make decisions about how to act in ways that seem quite free of obvious laws.
For while it is quite implausible that some simple chemical process could successfully assemble a traditional computer out of atoms, it seems quite plausible that this could be done for something like a rule 110 cellular automaton.
But while traditional engineering has usually ended up finding ways to avoid searches for the limited kinds of systems it considers, the phenomenon of computational irreducibility makes it inevitable that if one considers all possible simple programs then finding particular forms of behavior can require doing searches that involve irreducibly large amounts of computational work.
But when n = 4 isotropy requires the {1, 1, 1, 1} and {1, 1, 2, 2} tensor components to have ratio β = 3 —while square symmetry allows these components to have any ratio. … In 3D no regular lattice forces isotropy beyond n = 2 , while in 4D the SO(8) lattice works up to n = 4 , in 8D the E 8 lattice up to n = 6 , and in 24D the Leech lattice up to n = 10 .
Similarly, in case (d) one sees r 0 growth, reflecting dimension 1, while in case (h) one sees r 2 growth, reflecting dimension 3.
So, for example, the smallest solution to x 2 61 y 2 +1 is x 1766319049 , y 226153980 , while the smallest solution to x 3 +y 3 z 3 +2 is x 1214928 , y 3480205 , z 3528875 .
And while ordinary integers still satisfy all the constraints, the system is sufficiently incomplete that all sorts of other objects with quite different properties also do.
And in this way one can readily tell, for example, that the first operator shown is idempotent, so that p ∘ p p , while both the first two operators are associative, so that (p ∘ q) ∘ r p ∘ (q ∘ r) , and all but the third operator are commutative, so that p ∘ q q ∘ p .
In recent times it has also begun to be possible to image local electrical and metabolic activity while the brain is in normal operation.
For example, while repetition has been much emphasized for several millennia, it is only in the past couple of decades that precise nesting has had much emphasis.
