Generalized Wrońskians. For n functions of several variables, a generalized Wronskian is a determinant of an n by n matrix with entries Di(fj) (with 0 ≤ i < n), where each Di is some constant coefficient linear partial differential operator of order i. If the functions are linearly dependent then all generalized Wronskians vanish.
In mathematics, Abel's identity (also called Abel's formula[1] or Abel's differential equation identity) is an equation that expresses the Wronskian of two solutions of a homogeneous second-order linear ordinary differential equation in terms of a coefficient of the original differential equation. The relation can be generalised to n th-order ...
Continuous track. Józef Maria Hoene-Wroński (Polish: [ˈjuzɛf ˈxɛnɛ ˈvrɔj̃skʲi]; French: Josef Hoëné-Wronski [ʒozɛf ɔɛne vʁɔ̃ski]; 23 August 1776 – 9 August 1853) was a Polish messianist philosopher, mathematician, physicist, inventor, lawyer, occultist [1] and economist. He was born as Hoëné to a municipal architect in ...
Hamming alleges that Einstein was so confident that his relativity theories were correct that the outcomes of observations designed to test them did not much interest him. If the observations were inconsistent with his theories, it would be the observations that were at fault. 2. Humans create and select the mathematics that fit a situation ...
t. e. In mathematics, variation of parameters, also known as variation of constants, is a general method to solve inhomogeneous linear ordinary differential equations. For first-order inhomogeneous linear differential equations it is usually possible to find solutions via integrating factors or undetermined coefficients with considerably less ...
Balancing of rotating masses. The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre ...
Neurath was seeking to improve his position within the Nazi regime; by repeatedly assuring Hitler during the Rhineland crisis that the French would do nothing without telling Hitler the source of his self-assurance, Neurath came across as a diplomat blessed with an uncanny intuition, something that improved his standing with Hitler.

Arm swing in human bipedal walking is a natural motion wherein each arm swings with the motion of the opposing leg. Swinging arms in an opposing direction with respect to the lower limb reduces the angular momentum of the body, balancing the rotational motion produced during walking. Although such pendulum-like motion of arms is not essential ...
