Worksheet time: 10mins
What is “emergence” in complex systems?
The process of data becoming centralized
The collapse of smaller systems into one
The rise of collective behavior from simple rules
The random breakdown of organization
The blending of unrelated system properties
Which example best shows emergence in action?
A colony of ants forming a trail
A single ant gathering food
A robot following a program
A tree growing in a forest
A human typing on a computer
What is self-organization in systems theory?
Centralized control from a lead agent
Development from artificial intelligence
Order arising without external direction
Systems adjusting from external feedback
An imposed structure from hierarchy
Which system is most likely to exhibit self-organization?
A top-down military command
A flock of birds flying in formation
A government ministry
A teacher giving classroom rules
A coded software algorithm
What does de-centralization refer to in systems?
Authority shifting to a single leader
Randomization of control points
Distribution of decision-making power
Physical dispersion of materials
Transfer of data to storage hubs
What is one benefit of decentralization in a system?
Faster central processing
Stronger top-down control
Complete randomness in actions
Better surveillance and order
More resilience and flexibility
In systems, feedback means:
Sending signals to other countries
Providing comments after testing
Removing noise from data
Returning outputs into inputs
Reporting opinions in surveys
What’s an example of negative feedback in biology?
Oxygen causing rapid breathing
Increased hunger from high sugar
Body temperature regulation
A wound healing over weeks
A muscle building through rest
What does determinism claim about the universe?
Free will controls all decisions
Events happen entirely by chance
Human choices override natural laws
The future cannot be predicted
Outcomes are pre-determined by prior states
Which belief most aligns with determinism?
Coincidences define everything
Choices are purely spontaneous
Every effect has a prior cause
Randomness creates order
Emotions dictate physics
What defines a chaotic system in science?
A system with no patterns
A system controlled by AI
A deterministic system with unpredictable behavior
A completely random system
A balanced and steady system
Which of these is an example of chaos in nature?
Clock ticking
Rainstorm repeating weekly
Weather patterns over weeks
Moon orbiting Earth
Plant growing toward the sun
In chaos theory, sensitivity to initial conditions means:
Reactions happen slowly over time
The system ignores small changes
Tiny changes lead to large outcomes
Inputs always equal the same outputs
Feedback loops are disabled
Which is a famous metaphor for sensitivity in chaos theory?
Schrödinger’s cat paradox
The snowball effect
The butterfly effect
The domino theory
Murphy’s law
The flocking model in complexity science refers to:
Controlled migration by leaders
Imitation of predator movement
Simple rules creating group motion
One bird guiding the others
Weather forcing birds to align
What do flocking algorithms often include?
Rules for authority rotation
Equations for chaos prediction
Rules for separation, alignment, cohesion
Laws of thermodynamic energy
Controls for nervous system response
The three-body problem is difficult because:
It requires advanced knowledge of chemistry
It applies only to black holes
The system becomes mathematically unstable
The bodies move at identical speeds
All orbits result in perfect repetition
The three-body problem shows limits of:
Newtonian determinism in prediction
Conservation of mass and energy
Calculus in modern math
The speed of light in physics
Climate models in statistics
Fractals are best described as:
Patterns with no structure
Shapes that exist only in fiction
Self-similar patterns at different scales
Curves that always end sharply
Figures created from real-life photos
Which natural example shows a fractal pattern?
A square table
A solid metal cube
A fern leaf
A flat highway
A plain sheet of paper
