The Indian Certificate of Secondary Education (ICSE) is a certificate awarded upon satisfactory result in an examination conducted by the Council for the Indian School Certificate Examinations, a private board designed to provide an examination in a course of general education, in accordance with the recommendations of the New Education Policy 2020 (), through the medium of English.
Over 2750 schools in India and abroad are affiliated to the CISCE. [2] It is also recognized as a 'Non-Governmental National Board of Secondary Education'. [6] CISCE conducts ICSE exam for Class 10 and ISC exam for Class 12.

Mathematics and physics have influenced each other over their modern history. Modern physics uses mathematics abundantly, [134] and is also considered to be the motivation of major mathematical developments. [135]
In mathematical physics, a lattice model is a mathematical model of a physical system that is defined on a lattice, as opposed to a continuum, such as the continuum of space or spacetime. Lattice models originally occurred in the context of condensed matter physics , where the atoms of a crystal automatically form a lattice.
Eigenmodes are useful in constructing a full solution to the wave equation, because each of them evolves in time trivially with the phase factor , so that a full solution can be decomposed into an eigenmode expansion: (,) = (,), or in terms of the plane waves, (,) = + (+) + () = + (+) + () = + (+), which is exactly in the same form as in the ...
The problem of two fixed centers conserves energy; in other words, the total energy is a constant of motion.The potential energy is given by =where represents the particle's position, and and are the distances between the particle and the centers of force; and are constants that measure the strength of the first and second forces, respectively.
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.
