Linear Interpolation

In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points. Lerp operations are built into the hardware of all modern computer graphics processors. They are often used as building blocks for more complex operations: for example, a bilinear interpolation can be accomplished in three lerps. Because this operation is cheap, it's also a good way to implement accurate lookup tables.

Science, Technology, Engineering, and Mathematics

STEM is an umbrella term used to group the distinct but related technical disciplines of science, technology, engineering, and mathematics. The term is typically used in the context of education policy or curriculum choices in schools. It has implications for workforce development, national security concerns (as a shortage of STEM-educated citizens can reduce effectiveness in this area), and immigration policy, concerning admitting foreign students and tech workers.

Ultra Low Emission Zone

The Ultra Low Emission Zone (ULEZ) is an area in London, England, where an emissions standard-based charge is applied to non-compliant road vehicles. Plans were announced by London Mayor Boris Johnson in March 2015 for the zone to come into operation in September 2020. Sadiq Khan, the subsequent mayor, introduced the zone early on 8 April 2019. The zone initially covered Central London, the same area as the existing London congestion charge and raised £224 million in 2022.
