Test tonight
Here are my proposed answers to the test.
A find myself annoyed at the idea of a test. Ha ha.
Here are my proposed answers to the test.
A find myself annoyed at the idea of a test. Ha ha.
- What is Universal Automatism?
- What is a computation?
- What is the dielectric tirade in the books title?
- What does it mean to say a computation P is unpredictable?
- What does it mean to say Q emulates P?
- What are Wolfram's four classes of computations?
- Boring
- Structured
- Really interesting
- Einstein's nightmare
- What is the PCE?
- What is the PCU?
- What does it mean to say a computation P is universal?
- What are rules 30 and 100 for 1-demensional cellular automata, and what are they interesting?
- What are some examples of computational speed up?
- What is Von Neuman's "Stored Program?"
- What are these cellular automata, Life, Vote, Brain, Rule 30, & 110?
- What are Belousov-Zhabotinsky scrolls and what are the rules that make them?
- Discuss Analog vs. Discrete?
- What are Real Number, or continuous value, CAs?
- What is the CA rule for wave equation like behavior? What is the CA for the heat rule?
- Now we are really getting hard.
- Wave: C-new = C + Avg- Neighborhood (C-old) - C-old
- Heat: C-new = (1 - a) * C + a * Avg-Neighborhood (C)
- Discuss the beach ball into the bin experiment. How can we say it is deterministic?
- Discuss what it means for a computation to be chaotic.
- What does Wolfram mean by Intrinsic Randomness, being unpredictable?
- How might we evade the apparent non-determinism of quantum mechanics?
- What are the computational requirements for life? And what
are the implications at a system level? - Why does Rucker call DNA a "tweak" parameters?
- Discuss morphogenesis? What are the CA rules that demonstrate morphogenesis?
- What are some of the Turing Patters?
- What are the CA rules that create chaotic population size? What is a logistic map?
- What are the elements required for an evolutionary systems?
- Discuss evolution as search in a fitness landscape.
The idea that everything in the universe is at its root a computation on some field.
A computation is a finite step well defined steps based on input.
The dielectric is the seeming contradiction between computation as represented in the idea of a life box that can computationally represent a person and the soul which viewed as an ethereal truth of "unknowable" quality. The resolution is the sea shell, which while a computation is unpredictable and unknowable except be carrying out the complete and irreducible computation.
It means that the order of steps in the computation cannot be reduced to discover the outcome.
Q emulates P iff every computation P can do Q can do better -- I joke -- Q comes up with the same answer as P given the same data.
The principle of computational equivalence. The idea that Rudy and I are equally sophisticated, along with sea shell.
The principle of computational unpredictability. Not only are Rudy and I equally sophisticated but we are both unpredictable, along wtih the sea shell.
A computation is universal iff it can carry out all computations.
I.e. it can emulate another computation.
These are two rules for cellular automata that show "gnarly"
behavior. That is the are class three computations.
Addition and subtraction with carry and borrow rather than counting. Integration rather than adding.
Well lets see. Is it like a computer? Is it like a set of instructions that look like data that are interpreted by a particular machine to carry out an algorithm?
This is much too hard, this isn't chemistry!
The are complex, gnarly patterns, that are more or less self-sustaining, that have a scroll like shape. The are create by activator inhibitor rules, logistic rules,
Analog is the idea that there are many, possibly infinite, states in a quantity, and discrete means there are few, usually 10s or 100s of states.
It is a CA where each cell is represented by a many level or continuous state value.
This is almost a language problem. After all what is that we mean by random if it is not that we can't predict which way the ball is going to bounce. But we can explain -- that is appeal to -- the minute unknowns, the position of the moon and planets to explain. I.e. to slightly different, if imperceptible, differences in initial conditions.
It is highly sensitive to differences in initial conditions.
Who knows, the man is crazzzy. See above.
We can appeal to hidden variables, we can assume the future effects the past, we can pray.
Reproduction + Morphogenesis + Homeostasis -> Life
Life -> Ecology + Evolution.
Because it is not a blueprint for life, but it needs the box.
activator-inhibitor
Cow Spots
Logistic Rule
Life
The fitness landscape may have many steep peaks and therefore search algorithms that of are the same dimensional complexity as the space cannot easily find the peeks, because they tend to get stuck at local maxima.
