Split-and-mix peptide library synthesis
Split-and-mix peptide library synthesis, also called divide-couple-recombine synthesis, is a solid-phase method devised by Árpád Furka in which resin beads each end up carrying one unique peptide sequence.
Split-brain
Split-brain: condition after corpus callosotomy, severing the corpus callosum to treat drug-resistant epilepsy. Studied by Sperry, Bogen, and Gazzaniga from the 1960s; classic left-hand/left-visual-field findings; debate over split versus unified consciousness.
Split-complex number
The split-complex number, also called a Lorentz or double number, is a number x + yj where j² = 1, unlike the complex unit i² = −1.
Split-cycle engine
A split-cycle engine is a reciprocating internal combustion engine that divides the four strokes between two paired cylinders joined by a crossover passage; designs date to 1872 but none are in series production.
Split-Dalmatia County

Split-plot design
A split-plot design is an experimental design applying hard-to-change factors to large whole plots and easy-to-change factors to nested subplots, giving two randomizations and two error terms.
Split-quaternion
The split-quaternion, also called a coquaternion or para-quaternion, is a four-dimensional non-commutative algebra over the real numbers, defined by James Cockle in 1849, containing zero divisors and isomorphic to 2 × 2 real matrices.
Split-ring resonator
A split-ring resonator (SRR) is a planar electromagnetic structure of metallic rings with small gaps, used as the meta-atom of metamaterials and as a sensing and circuit element.
Split-step Fourier method
The split-step Fourier method (SSFM) is a numerical technique for integrating evolution equations, most prominently the nonlinear Schrödinger equation, by alternating linear substeps in Fourier space with nonlinear substeps in physical space.
Split-system air conditioner
A split-system air conditioner cools (and often heats) through separate outdoor and indoor units linked by refrigerant piping rather than ductwork, avoiding the roughly 30% energy losses of ducted air.

Split-thickness skin grafting transplants a thin layer of skin, the epidermis plus part of the dermis, from a donor site to cover wounds elsewhere on the body.

Splitting field
A splitting field of a polynomial over a field F is the smallest field extension of F in which the polynomial factors completely into linear factors.
Splitting functions
Splitting functions are the perturbatively calculable kernels of the DGLAP equations, giving the probability density for one parton to emit another in QCD; the complete three-loop functions have been known since 2004.
Splitting of the Moon
The splitting of the moon (Arabic shaqq al-qamar) is a reported miracle of Muhammad in which the moon divided into two parts, based on Quran 54:1.
