Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Response times are long due to traffic, poor coordination, and scarce vehicles. Tech-enabled ambulance dispatch and motorcycle first responder networks could reduce mortality.

Families facing crises often pull children from school first, disrupting education continuity for the most vulnerable. Emergency cash-transfer programs tied to school attendance could protect continuity during shocks.

Most deaths are preventable but occur due to lack of skilled birth attendants, blood banks, and emergency transport in rural areas. Builders could create low-cost obstetric emergency referral networks using mobile alerts.

Ramsey-type problems ask whether order must always emerge within sufficiently large or complex systems, and while some cases are proven, the general boundaries remain incompletely mapped. This connects deeply to combinatorics and the philosophy of mathematical order.

Certain recursively defined sequences appear statistically random for enormous stretches, yet whether hidden structure always eventually emerges remains an open and evolving question. This connects deeply to both number theory and the study of pseudorandomness.
