He was a professor at the department of Physics at the Ramsaday College, University of Calcutta. [1] He was a visiting faculty at the Al-Ameen Mission . [ 2 ] [ 3 ] Professor Dwari co-authored the physics textbooks, Chhaya Practical Physics Class 12 , Chhaya Padarthabidya Class 12 (2023–24), and Chhaya Byabaharik Padarthabidya Class 12 .
Physics Wallah, or "PW", was founded in 2016 as a YouTube channel hosted by Alakh Pandey, an educator hailing from Prayagraj, Uttar Pradesh. The channel was initially focused on teaching the physics curriculum for the Joint Entrance Examinations (JEE), a popular entrance examination in India. [2]
Nuclear Physics: Fundamentals and Applications (organized by National Program for Technology Enhanced Learning, NPTEL) Learning Physics through Simple Experiments (Massive Online Open Course in 2016) Physics of Semiconductors (Massive Online Open Course in 2017) B.Sc. courses in Hindi - Basics of Special Theory of Relativity (2018)
Physics Galaxy was founded as an online learning portal by Ashish Arora. [2] It was founded as an initiative to coach students for free especially for those in rural areas, who cannot afford expensive coaching facilities. Later in 2011, a YouTube channel of the same name was founded. [3] [4]
This derivation is now generally accepted as a historical landmark in physics by virtue of uniting electricity, magnetism and optics into one single unified theory. The displacement current term is now seen as a crucial addition that completed Maxwell's equations and is necessary to explain many phenomena, most particularly the existence of ...
In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.
Meenakshi Narain, Chair of the Department of Physics at Brown University, contributed to the discovery of top quark in 1995 and Higgs Boson in 2012. Jai Prakash Nishad, Member of Parliament, Rajya Sabha from Uttar Pradesh; Jagdambika Pal, a Bharatiya Janta Party MP from Doomariyaganj; Mata Prasad Pandey, former speaker of the Uttar Pradesh ...
There are many different effective medium approximations, [5] each of them being more or less accurate in distinct conditions. Nevertheless, they all assume that the macroscopic system is homogeneous and, typical of all mean field theories, they fail to predict the properties of a multiphase medium close to the percolation threshold due to the absence of long-range correlations or critical ...
