Evidence-based policyEvidence-based policy is a concept in public policy that advocates for policy decisions to be grounded on, or influenced by, rigorously established objective evidence. This concept presents a stark contrast to policymaking predicated on ideology, 'common sense,' anecdotes, or personal intuitions. The approach mirrors the effective altruism movement's philosophy within governmental circles. The methodology employed in evidence-based policy often includes comprehensive research methods such as randomized controlled trials (RCT).
Projectile motionProjectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only. In the particular case of projectile motion on Earth, most calculations assume the effects of air resistance are passive and negligible. The curved path of objects in projectile motion was shown by Galileo to be a parabola, but may also be a straight line in the special case when it is thrown directly upward or downward.
Five points determine a conicIn Euclidean and projective geometry, five points determine a conic (a degree-2 plane curve), just as two (distinct) points determine a line (a degree-1 plane curve). There are additional subtleties for conics that do not exist for lines, and thus the statement and its proof for conics are both more technical than for lines. Formally, given any five points in the plane in general linear position, meaning no three collinear, there is a unique conic passing through them, which will be non-degenerate; this is true over both the Euclidean plane and any pappian projective plane.
Absolute rotationIn physics, the concept of absolute rotation—rotation independent of any external reference—is a topic of debate about relativity, cosmology, and the nature of physical laws. For the concept of absolute rotation to be scientifically meaningful, it must be measurable. In other words, can an observer distinguish between the rotation of an observed object and their own rotation? Newton suggested two experiments to resolve this problem.
Shadow (psychology)In analytical psychology, the shadow (also known as ego-dystonic complex, repressed id, shadow aspect, or shadow archetype) is an unconscious aspect of the personality that does not correspond with the ego ideal, leading the ego to resist and project the shadow. In short, the shadow is the self's emotional blind spot, projected (as archetypes—or, metaphorical sense-image complexes, personified within the collective unconscious); e.g., trickster. Defence mechanism and Anxiety Dark triad and Otto F.
Carl JungCarl Gustav Jung (jʊŋ ; kaʁl ˈjʊŋ; 26 July 1875 – 6 June 1961) was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. Jung's work has been influential in the fields of psychiatry, anthropology, archaeology, literature, philosophy, psychology, and religious studies. He worked as a research scientist at the Burghölzli psychiatric hospital, in Zurich, under Eugen Bleuler. Jung established himself as an influential mind, developing a friendship with Sigmund Freud, founder of psychoanalysis, conducting a lengthy correspondence, paramount to their joint vision of human psychology.
Object relations theoryObject relations theory is a school of thought in psychoanalytic theory and psychoanalysis centered around theories of stages of ego development. Its concerns include the relation of the psyche to others in childhood and the exploration of relationships between external people, as well as internal images and the relations found in them. Thinkers of the school maintain that the infant's relationship with the mother primarily determines the formation of its personality in adult life.
