Change is now: confident

Description

This lecture discusses the importance of change and the need to avoid immobilism, encouraging a confident and solidary approach towards transforming society. It also touches on the critical dialogue and the repression of ideas.

Transformation matrix

In linear algebra, linear transformations can be represented by matrices. If is a linear transformation mapping to and is a column vector with entries, then for some matrix , called the transformation matrix of . Note that has rows and columns, whereas the transformation is from to . There are alternative expressions of transformation matrices involving row vectors that are preferred by some authors. Matrices allow arbitrary linear transformations to be displayed in a consistent format, suitable for computation.

Geometric transformation

In mathematics, a geometric transformation is any bijection of a set to itself (or to another such set) with some salient geometrical underpinning. More specifically, it is a function whose domain and range are sets of points — most often both or both — such that the function is bijective so that its inverse exists. The study of geometry may be approached by the study of these transformations. Geometric transformations can be classified by the dimension of their operand sets (thus distinguishing between, say, planar transformations and spatial transformations).

Transformation (function)

In mathematics, a transformation is a function f, usually with some geometrical underpinning, that maps a set X to itself, i.e. f: X → X. Examples include linear transformations of vector spaces and geometric transformations, which include projective transformations, affine transformations, and specific affine transformations, such as rotations, reflections and translations.

Solidarity

Solidarity or solidarism is an awareness of shared interests, objectives, standards, and sympathies creating a psychological sense of unity of groups or classes. Unlike collectivism, solidarism does not reject individuals and sees individuals as the basis of society. It refers to the ties in a society that bind people together as one. The term is generally employed in sociology and the other social sciences as well as in philosophy and bioethics.

Solidarity economy

Solidarity economy or Social and Solidarity Economy (SSE) refers to a wide range of economic activities that aim to prioritize social profitability instead of purely financial profits. A key feature that distinguishes solidarity economy entities from private and public enterprises is the participatory and democratic nature of governance in decision-making processes as one of the main principles of the SSE sector. Active participation of all people involved in decision-making procedures contributes to their empowerment as active political subjects.
