A solution in radicals or algebraic solution is an expression of a solution of a polynomial equation that is algebraic, that is, relies only on addition, subtraction, multiplication, division, raising to integer powers, and extraction of n th roots (square roots, cube roots, etc.). A well-known example is the quadratic formula
For a long time, the Wobbly philosophy was based on the belief that organizing and developing solidarity constituted the best radical education for workers. [110] The perceptions expressed in the IWW Preamble coincided with the Colorado miners' personal experiences with capitalism, and also with their feelings about the United Mine Workers ...
Radical centrism, also called the radical center, the radical centre, and the radical middle, is a concept that arose in Western nations in the late 20th century. The radical in the term refers to a willingness on the part of most radical centrists to call for fundamental reform of institutions. [ 1 ]
Rules for Radicals: A Pragmatic Primer for Realistic Radicals is a 1971 book by American community activist and writer Saul Alinsky about how to successfully run a movement for change. It was the last book written by Alinsky, and it was published shortly before his death in 1972.
Lean thinking is a management framework made up of a philosophy, practices and principles which aim to help practitioners improve efficiency and the quality of work. Lean thinking encourages whole organisation participation. The goal is to organise human activities to deliver more benefits to society and value to individuals while eliminating ...

TRIZ flowchart Contradiction matrix 40 principles of invention, principles based on TRIZ. One tool which evolved as an extension of TRIZ was a contradiction matrix. [14] The ideal final result (IFR) is the ultimate solution of a problem when the desired result is achieved by itself.
is the simplest equation that cannot be solved in radicals, and that almost all polynomials of degree five or higher cannot be solved in radicals. The impossibility of solving in degree five or higher contrasts with the case of lower degree: one has the quadratic formula, the cubic formula, and the quartic formula for degrees two, three, and ...
