Kindness

Kindness: friendly, generous, considerate behavior benefiting others; studied as a virtue candidate (Kristjánsson disputes this), a VIA character strength under humanity, and a defined operational value in healthcare.

Kindred (novel)

Kindred is Octavia E. Butler's 1979 neo-slave narrative novel in which Dana Franklin, a Black woman in 1976 Los Angeles, is repeatedly transported to an early 19th-century Maryland plantation; adapted as a 2017 graphic novel and a 2022 FX/Hulu series.

Kindred Selector

Kindred Selector is a San Francisco venture capital fund family and companion vehicle of Kindred Ventures, the earliest-stage firm founded by Steve Jang, with Kanyi Maqubela as managing partner.

Kindred Spirits

Kindred Spirits is an 1849 oil painting by Asher B. Durand showing the painter Thomas Cole and poet William Cullen Bryant in the Catskill Mountains, painted as a memorial to Cole.

Kindred Ventures

Kindred Ventures is a San Francisco venture capital firm founded by Steve Jang and Kanyi Maqubela that invests at the pre-seed and seed stages in technology startups.

Kindu

Kindu (Kindu-Port-Empain), capital of Maniema province, DR Congo, on the Lualaba River; river-rail interchange with the SNCC line to Katanga, a domestic airport, about 172,000-235,000 residents, and severe transport isolation.

Kinect

Kinect (code name Project Natal) is Microsoft's motion-sensing peripheral for Xbox 360, Xbox One, and Windows, using PrimeSense infrared depth sensing, 20-joint skeletal tracking, and voice control; about 35 million sold, discontinued 2017.

Kinectin

Kinectin (KTN1, kinesin receptor, CG-1 antigen) is a 160-kDa single-pass type II ER membrane protein that binds kinesin, anchoring it for vesicle motility, ER extension, and focal adhesion growth; KTN1 is upregulated in many cancers.

Kinéis

Kinéis is a French satellite operator based in Toulouse, spun out of CLS with CNES in 2019, whose 25-nanosatellite constellation for global IoT connectivity completed deployment in March 2025.

KineMaster

KineMaster is a mobile video editing application for Android, iOS, and iPadOS, developed by Seoul-based KineMaster Corporation and known for its multi-layer timeline, chroma key, and 4K export.

Kinematic calibration

Kinematic calibration is a robotics engineering method that identifies and corrects errors in a robot's kinematic model, using measured end-effector pose data to improve absolute positioning accuracy.

Kinematic chain

A kinematic chain is a system of rigid bodies, called links, connected by joints so each link is constrained by its neighbors; with one link fixed, it is a mechanism.

Kinematic coupling

A kinematic coupling is a mechanical interface using exactly six contact points to constrain two rigid parts, allowing repeated re-mating with sub-micron to micron repeatability in optics, robotics, and semiconductor equipment.

Kinematic design

Kinematic design is a precision-engineering approach that constrains a body with exactly as many point contacts as degrees of freedom to restrain, giving highly repeatable positioning.

Kinematic mapping

Kinematic mapping is a mathematical tool that assigns each rigid-body displacement a point in a projective space, so mechanism synthesis problems become questions about curves and surfaces.

Kinematic singularity

A kinematic singularity is a robot manipulator configuration where the Jacobian loses rank, so the end-effector cannot move in some directions and joint velocities can spike.

Kinematic synthesis of linkages

Kinematic synthesis of linkages is the branch of mechanism design that determines linkage dimensions and geometry so the links produce a prescribed motion, path, or function.

Kinematic time dilation in gravitational fields

Kinematic time dilation in gravitational fields is the velocity-dependent part of a moving clock's rate in a gravitational potential, always combined with gravitational redshift in tests.

Kinematic wave theory

Kinematic wave theory is a simplified description of unsteady shallow water flow in which friction balances the water's weight component, so flow-dependent celerity can steepen waves into shocks.

Kinematics

Kinematics, often called the geometry of motion, is the branch of mechanics that describes motion without reference to the forces causing it, using position, velocity, and acceleration.

Kinesics

Kinesics, also known as kinemics, is the study of body movements, such as gestures, facial expressions, and posture, as communication in social interaction, often called body language.

Kinesin

Kinesin (kinesin superfamily proteins, KIFs) is a family of ATP-driven motor proteins that walk along microtubules, taking 8-nm steps at one ATP per step; 45 human KIFs in 14 families transport cargo, build spindles, and are linked to neurological disease and cancer.

Kinesin light chain

Kinesin light chain (KLC1-KLC4) is the cargo-binding, autoinhibitory subunit of kinesin-1; its TPR domain binds W-acidic and Y-acidic cargo motifs, with N343 giving KLC1 its JIP1 specificity.

Kinesin motor domain

Kinesin motor domain: the ~350-amino-acid catalytic head shared by kinesin superfamily motors, binding ATP and tubulin; drives 8-nm, one-ATP-per-step processive stepping via neck linker docking and gating, and can alter the microtubule lattice.

Kinesin-like

Kinesin-like (IPR022164; Pfam DUF3694, PF12473) is a conserved 131-151 amino acid domain of kinesin-family motor proteins such as KIF1A, KIF1B, KIF13A, and KIF13B, carrying a fully conserved tryptophan and mediating cargo binding in axonal transport and angiogenesis.

Kinesiology

Kinesiology, also known as human kinetics, is the scientific study of human movement, spanning biomechanics, exercise physiology, and motor behavior. In Canada it is also a regulated health profession.

Kinesthetic learning

Kinesthetic learning (K in the VAK and VARK models) is the claim that some people learn best through movement and hands-on activity. Controlled studies largely fail to confirm meshing instruction to this style improves outcomes, though embodied, movement-based teaching has separate support.

Kinesthetic teaching

Kinesthetic teaching is a robot programming method in which a human physically moves the robot through a task, so its own sensors record the demonstration as training data.
