A correction appeared in volume 5, pp. 98–99, Berichtigungen. First appearance (page 443) of the equation E = mc 2. This paper also marks the beginning of Einstein's long development of general relativity; here he derives the equivalence principle, gravitational redshift, and the gravitational bending of light. Einstein returns to these ...
Millennium Prize Problems. The Navier–Stokes existence and smoothness problem concerns the mathematical properties of solutions to the Navier–Stokes equations, a system of partial differential equations that describe the motion of a fluid in space. Solutions to the Navier–Stokes equations are used in many practical applications.
The Navier–Stokes equations (/ n æ v ˈ j eɪ s t oʊ k s / nav-YAY STOHKS) are partial differential equations which describe the motion of viscous fluid substances. They were named after French engineer and physicist Claude-Louis Navier and the Irish physicist and mathematician George Gabriel Stokes. They were developed over several decades ...
The newton-second (also newton second; symbol: N⋅s or N s) [1] is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second ( kg⋅m/s ). One newton-second corresponds to a one- newton force applied for one second. It can be used to identify the resultant ...
Satyendra Nath Bose FRS, MP (/ ˈ b oʊ s /; 1 January 1894 – 4 February 1974) was an Indian theoretical physicist and mathematician.He is best known for his work on quantum mechanics in the early 1920s, in developing the foundation for Bose–Einstein statistics and the theory of the Bose–Einstein condensate.
students’ ability to read and understand the contents. However, senior secondary school physics textbooks (69%) was found to be most readable, seconded by ordinary level physics (64%), followed by principle of physics while science teacher association of Nigeria (STAN) physics (15%) was found to be least readable by the students.
Beyond the Standard Model. In physics, Kaluza–Klein theory ( KK theory) is a classical unified field theory of gravitation and electromagnetism built around the idea of a fifth dimension beyond the common 4D of space and time and considered an important precursor to string theory. In their setup, the vacuum has the usual 3 dimensions of space ...
Kyungpook National University, Korea. F TRENDS IN PHYSICS EDUCATION RESEARCH USING TOPIC MODELINGEunjeong YunIntroductionMany physicists. teach students in university and physics educators teach preservice physics teachers. Therefore. for both groups, the question of how physics should be taught is an important issue. In terms of research, h.
