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. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
In mathematics, the Navier–Stokes equations are a system of nonlinear partial differential equations for abstract vector fields of any size. In physics and engineering, they are a system of equations that model the motion of liquids or non-rarefied gases (in which the mean free path is short enough so that it can be thought of as a continuum mean instead of a collection of particles) using ...
The Pakistan Physical Society, also known as Pakistan Physics Society, (Urdu: پاکستان مصاحبتِ طبیعات) is an academic and professional physics society of Pakistan's academicians and physicists, dedicated for the development and research in physics. [1]
Dr. Abdus Salam, the first Pakistani winner of the Nobel Prize in Physics, was the father of physics research in Pakistan. Under his watchful direction, mathematicians and physicists tackled the greatest and outstanding problems in physics and mathematics.
The three-body problem is a special case of the n-body problem. Historically, the first specific three-body problem to receive extended study was the one involving the Earth, the Moon, and the Sun. [2] In an extended modern sense, a three-body problem is any problem in classical mechanics or quantum mechanics that models the motion of three ...
A Fermi problem (or Fermi question, Fermi quiz), also known as an order-of-magnitude problem, is an estimation problem in physics or engineering education, designed to teach dimensional analysis or approximation of extreme scientific calculations. Fermi problems are usually back-of-the-envelope calculations.
National Science Talent Contest or NSTC is an extension of the National Physics Talent Contest launched by PIEAS in 1995 on the directive of the then President of Pakistan. The purpose of the NSTC is to inspire the youth of the Nation to opt for careers in science, and mathematics and to prepare young students for participation in International ...
The National Centre for Physics [nb 1] is a federally funded research institute and national laboratory co-located near Quaid-i-Azam University in Pakistan [1] [2]. Founded in 1999, [1] the site is dedicated for understanding and advancement of the physical sciences and mathematical logic – the site is located in Islamabad in Pakistan.
