NCERT has a comprehensive extension program in which departments of the National Institute of Education, Regional Institute of Education, Central Institute of Vocational Education, and field coaches' offices in the states are engaged in activities. Several programs are organized in rural and backward areas to reach out to functionaries in these ...
Painting of Hendrik Lorentz by Menso Kamerlingh Onnes, 1916 Portrait by Jan Veth Lorentz' theory of electrons. Formulas for the Lorentz force (I) and the Maxwell equations for the divergence of the electrical field E (II) and the magnetic field B (III), La théorie electromagnétique de Maxwell et son application aux corps mouvants, 1892, p. 451.
The examination consisted of one paper containing 180 objective type questions from Physics, Chemistry and Biology (Botany & Zoology), having 45 questions from each subject. The exam duration was 3 hours. Each question carried 4 marks. For each incorrect response, one mark used to be deducted from the total score.

where = is the reduced Planck constant.. The quintessentially quantum mechanical uncertainty principle comes in many forms other than position–momentum. The energy–time relationship is widely used to relate quantum state lifetime to measured energy widths but its formal derivation is fraught with confusing issues about the nature of time.
In his book, Surely You're Joking, Mr. Feynman!, the late physics Nobel Prize laureate Richard P. Feynman described his experiences as a member of a committee that evaluated science textbooks. [58] At some instances, there were nonsensical examples to illustrate physical phenomena; then a company sent – for reasons of timing – a textbook ...
In physics and chemistry, a degree of freedom is an independent physical parameter in the chosen parameterization of a physical system.More formally, given a parameterization of a physical system, the number of degrees of freedom is the smallest number of parameters whose values need to be known in order to always be possible to determine the values of all parameters in the chosen ...
Within the Standard Model, such a dipole is predicted to be non-zero but very small, at most 10 −38 e⋅cm, [2] where e stands for the elementary charge. The discovery of a substantially larger electron electric dipole moment would imply a violation of both parity invariance and time reversal invariance .
