Feedback loop
A loop shows how outputs can alter future inputs; the sign and delay of each relation matter.

Visual Knowledge Gallery
Original text-based explainers. Use the caption and description; diagrams are simplified models.
Signal and noise
A measured pattern sits alongside variation, error and selection effects.
Bayesian evidence
Prior belief and likelihood combine into a revised probability under a stated model.
Research lifecycle
Questions, methods, evidence and communication connect in a revisable cycle.
Internet architecture
Applications, transport and network layers organize different responsibilities.
Value chain
Activities connect inputs to outputs, with costs and effects at each boundary.
Knowledge graph
Nodes and typed edges represent entities and relations with provenance.
Logistics system
Routes connect supply and demand subject to capacity constraints.
Scientific inquiry
A question, method, observation and critique support a revisable explanation.
Heat transfer
Energy moves through conduction, convection and radiation mechanisms.
Scholarly publication
A manuscript moves through submission, review, revision and publication decisions.
Supply and demand
Linear curves can illustrate an equilibrium under simplified assumptions.
Ecosystem interactions
Organisms and environmental conditions form relationships across scales.
Sustainability decision cycle
A decision connects a boundary, indicators, trade-offs and review.
Risk matrix
Likelihood and consequence categories help structure discussion, not predict events.
Stakeholder map
A map highlights relationships and missing voices around a decision.
Sampling variation
Different samples from one synthetic population can produce different estimates.
Project timeline
Milestones make work and dependencies visible.
Accessibility review
Content, controls and alternatives shape whether a resource can be used.
Algorithm complexity
The number of steps can grow differently as input size increases.
Urban mobility
Routes, access points and capacity interact in a simplified network.
Energy balance
A boundary clarifies inputs, outputs and stored energy.
Evidence ladder
Claims, observations and interpretations have different evidential roles.
Scenario assumptions
A transparent scenario connects explicit inputs to an illustrative outcome.
