Here is a question about this article: Lie groups are of fundamental importance in modern physics: Noether's theorem links continuous symmetries to conserved quantities. Rotation, as well as translations in space and time are basic symmetries of the laws of mechanics. They can, for instance, be used to construct simple modelsimposing, say, axial symmetry on a situation will typically lead to significant simplification in the equations one needs to solve to provide a physical description.v["] Another example are the Lorentz transformations, which relate measurements of time and velocity of two observers in motion relative to each other. They can be deduced in a purely group-theoretical way, by expressing the transformations as a rotational symmetry of Minkowski space. The latter servesin the absence of significant gravitationas a model of space time in special relativity. The full symmetry group of Minkowski space, i.e. including translations, is known as the Poincare group. By the above, it plays a pivotal role in special relativity and, by implication, for quantum field theories. Symmetries that vary with location are central to the modern description of physical interactions with the help of gauge theory.
What is the answer to this question: What concept relates measurements of time and velocity of two observers in motion relative to each other?
****
So... Lorentz transformations

Here is a question about this article: The earliest surviving written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century AD. According to Vitruvius, a good building should satisfy the three principles of firmitas, utilitas, venustas, commonly known by the original translation firmness, commodity and delight. An equivalent in modern English would be:
What is the answer to this question: What is the commonly seen English translation of the three principles?
****
So... firmness, commodity and delight

Here is a question about this article: The United States is the chief remaining nation to assign official responsibilities to a region called the Near East. Within the government the State Department has been most influential in promulgating the Near Eastern regional system. The countries of the former empires of the 19th century have in general abandoned the term and the subdivision in favor of Middle East, North Africa and various forms of Asia. In many cases, such as France, no distinct regional substructures have been employed. Each country has its own French diplomatic apparatus, although regional terms, including Proche-Orient and Moyen-Orient, may be used in a descriptive sense. The most influential agencies in the United States still using Near East as a working concept are as follows.

So...
The United States
