The pascal is the SI unit of pressure:For a uniform normal force of $10\mathrm{N}$ over area $0.02{\mathrm{m}}^2$, the pressure is $500\mathrm{Pa}$. The unit expresses a force per area, rather than the total force alone. ^[ref].

The newton is the SI unit of force:This combines the units of mass and acceleration in Newton's second law. ^[ref].

The mole is the SI base unit of amount of substance. One mole contains exactly $6.02214076\times 10^{23}$ specified entities, as fixed by the Avogadro constant. It counts entities rather than a fixed mass or volume. ^[ref]

A communication object on which software threads send or receive IPC messages. In seL4, an IPC endpoint is an operating-system kernel object with waiting senders or receivers; access requires a suitable security capability. ^[ref]

Here light intensity means the time-averaged energy flux per perpendicular area for light. It is the propagation-direction component of the averaged Poynting vector. For plane electromagnetic waves in the same medium it is proportional to squared electric field wave amplitude, giving the projection-squared factor in Malus's law.

For a field evolving by a Hamiltonian partial differential equation, infinite-dimensional integrability combines sufficiently rich commuting conservation laws with a mechanism such as the inverse scattering transform or a spectral coordinate system that linearizes evolution. Lax equations supply spectral invariants; Lenard-Magri recursions supply commuting Hamiltonians when their solvability conditions hold. Infinite many conserved quantities alone do not prove completeness or an infinite-dimensional action-angle theorem: the function space, boundary conditions and analytic independence all matter.

A side effect is an observable state change accompanying evaluation beyond the returned value. Writing a file, changing a shared variable or modifying an argument object are examples. A function can return the same numeric answer on repeated calls while producing different observable behaviour by appending to a log each time. Replacing the second call with a cached result then changes the program's behaviour. A pure function avoids such observable effects and returns its result from its inputs alone; languages can still provide explicit mechanisms for sequencing necessary effects.

PNG is a file format for raster images with lossless source coding of the encoded image data. Its first W3C Recommendation, dated 1 October 1996, described a portable replacement for earlier image formats; this situates the design in exchanging images reliably between systems.^[ref]
