Metallic and insulating states of materials can be considered as different quantum phases of matter connected by a metal-insulator transition. Materials can be classified by the structure of their Fermi surface and zero-temperature dc conductivity as follows: [4] Metal: Fermi liquid: a metal with well-defined quasiparticle states at the Fermi ...
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object's mass and volume, which are two extensive properties, is density, which is an intensive property. [9] More generally properties can be combined to give new properties, which may be called derived or composite properties.
Greg Gumbel, the renowned CBS Sports anchor and commentator, has died at the age of 78. His family confirmed the news in a statement on Friday, saying:
The TLE format is a de facto standard for distribution of an Earth-orbiting object's orbital elements. A TLE set may include a title line preceding the element data, so each listing may take up three lines in the file, in which case the TLE is referred to as a three-line element set (3LE), instead of a two-line element set (2LE). The title is ...

[2] TLE is also referred to as CP-TLE for Career Pathways in Technology and Livelihood Education. [3] The 2010 Secondary Education Curriculum allocates 240 minutes per week for CP-TLE, which is equivalent to 1.2 units. However, CP-TLE is required to include practical work experience in the community, which may extend beyond its specified school ...
