https://en.wikipedia.org/wiki/New%20Zealand%20flag%20debate | The New Zealand flag debate is a question over whether the national flag should be changed. For several decades, alternative designs have been proposed, with varying degrees of support. There is no consensus among proponents of changing the flag as to which design should replace the current one. Common criticisms of th... |

https://en.wikipedia.org/wiki/Eotragus | Eotragus is an extinct genus of early bovid. Species belonging to the genus inhabited Europe, Africa, and Asia during the Miocene some 20-18 million years ago. It is related to the modern nilgai and four-horned antelope. It was small and probably lived in woodland environments.

https://en.wikipedia.org/wiki/Matter%20power%20spectrum | The matter power spectrum describes the density contrast of the universe (the difference between the local density and the mean density) as a function of scale. It is the Fourier transform of the matter correlation function. On large scales, gravity competes with cosmic expansion, and structures grow according to lin... |
https://en.wikipedia.org/wiki/Susceptibility%20weighted%20imaging | Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images. This method exploits the suscepti... |

https://en.wikipedia.org/wiki/Light-cone%20coordinates | In physics, particularly special relativity, light-cone coordinates, introduced by Paul Dirac and also known as Dirac coordinates, are a special coordinate system where two coordinate axes combine both space and time, while all the others are spatial.
Motivation
A spacetime plane may be associated with the plane of s... |
https://en.wikipedia.org/wiki/Light%20cone%20gauge | In theoretical physics, light cone gauge is an approach to remove the ambiguities arising from a gauge symmetry. While the term refers to several situations, a null component of a field A is set to zero (or a simple function of other variables) in all cases.
The advantage of light-cone gauge is that fields, e.g. gluon... |
https://en.wikipedia.org/wiki/Light%20front%20quantization | The light-front quantization
of quantum field theories
provides a useful alternative to ordinary equal-time
quantization. In
particular, it can lead to a relativistic description of bound systems
in terms of quantum-mechanical wave functions. The quantization is
based on the choice of light-front coordinates,
