All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10.
The National Science Talent Search Scheme (NTSS) underwent a major change in the year 1976 with the introduction of the 10+2+3 pattern of education. The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII.
However, the Term-I examination was criticised by many for having wrong answer keys, tough question papers and wrong or controversial questions with a question being dropped in Sociology exam of class 12 and a paragraph in English Language and Literature exam for class 10 by CBSE following which CBSE dropped the experts who set the Sociology ...
The scattering of X-rays can also be described in terms of scattering cross sections, in which case the square ångström is a convenient unit: 1 Å 2 = 10 −20 m 2 = 10 000 pm 2 = 10 8 b. The sum of the scattering, photoelectric, and pair-production cross-sections (in barns) is charted as the "atomic attenuation coefficient" (narrow-beam), in ...
Any such term must be both gauge and reference-frame invariant, otherwise the laws of physics would depend on an arbitrary choice or the frame of an observer. Therefore, the global Poincaré symmetry , consisting of translational symmetry , rotational symmetry and the inertial reference frame invariance central to the theory of special ...
The thermodynamic square (also known as the thermodynamic wheel, Guggenheim scheme or Born square) is a mnemonic diagram attributed to Max Born and used to help determine thermodynamic relations. Born presented the thermodynamic square in a 1929 lecture. [1] The symmetry of thermodynamics appears in a paper by F.O. Koenig. [2]

In atomic physics, spin–orbit coupling, also known as spin-pairing, describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. the electron spin and its motion around an atomic nucleus. One of its effects is to separate the energy of internal states of the atom, e.g. spin-aligned and ...
