Welcome to the community hub built on top of the Grand Challenges Wikipedia article.
Here, you can discuss, collect, and organize anything related to Grand Challenges. The
purpose of the hub is to connect people, foster deeper knowledge, and help improve
the root Wikipedia article.
Grand Challenges are difficult but important problems set by various institutions or professions to encourage solutions or advocate for the application of government or philanthropic funds especially in the most highly developed economies [1] and
... energize not only the scientific and engineering community, but also students, journalists, the public, and their elected representatives, to develop a sense of the possibilities, an appreciation of the risks, and an urgent commitment to accelerate progress.[2]
Grand challenges are more than ordinary research questions or priorities, they are end results or outcomes that are global in scale; very difficult to accomplish, yet offer hope of being ultimately tractable; demand an extensive number of research projects across many technical and non-technical disciplines and accompanied by well-defined metrics. [1] Lastly, Grand challenges "require coordinated, collaborative, and collective efforts"[3] and must capture "the popular imagination, and thus political support."[1]

In management and organization studies, an important research agenda has evolved around Grand Challenges.[9][10] However, it is being criticized.[11][12]
The presidential Office of Science and Technology Policy in the United States set a first list of grand challenges in the late 1980s, to direct research funding for high-performance computing. A grand challenge is a fundamental problem in science or engineering, with broad applications, whose solution would be enabled by the application of high performance computing resources that could become available in the near future. Examples of these grand challenges were said to be:[13]
Computational fluid dynamics for
the design of hypersonic aircraft, efficient automobile bodies, and extremely quiet submarines
weather forecasting for short- and long-term effects
efficient recovery of oil, and for many other applications
Electronic structure calculations for the design of new materials such as
chemical catalysts
immunological agents
superconductors
Plasma dynamics for fusion energy technology and for safe and efficient military technology
Calculations to understand the fundamental nature of matter, including quantum chromodynamics and condensed matter theory
