List of unsolved problems may refer to several notable conjectures or open problems in various academic fields: Natural sciences, engineering and medicine [ edit ]
Social scientists have suggested that nanotechnology's social issues should be understood and assessed not simply as "downstream" risks or impacts. Rather, the challenges should be factored into "upstream" research and decision making in order to ensure technology development that meets social objectives [1]
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
A sample of 229 nearby "thick" disk stars has been used to investigate the existence of an age-metallicity relation in the Galactic thick disk and indicates that there is an age-metallicity relation present in the thick disk. [13] [14] Stellar ages from asteroseismology confirm the lack of any strong age-metallicity relation in the Galactic ...
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 ...
The problem to determine all positive integers such that the concatenation of and in base uses at most distinct characters for and fixed [citation needed] and many other problems in the coding theory are also the unsolved problems in mathematics.
486 Chinese cancer researchers were found guilty of engaging in a fraudulent peer-review scheme by China's Ministry of Science and Technology. The investigation was initiated after the retraction of 107 papers published in Tumor Biology between 2012 and 2016. [329] [330] This is reported to be the most papers retracted from one journal. [331]
For example, the innovation agencies of Argentina, Brazil, and Uruguay have issued calls for research proposals with an expedited approval process through early April 2020. Peru's two innovation agencies reduced their own response time to two weeks, as documented in the UNESCO Science Report (2021).
