112Lorentz scalar — In physics a Lorentz scalar is a scalar which is invariant under a Lorentz transformation. A Lorentz scalar is generated from vectors and tensors. While the vectors and tensors are altered by Lorentz transformations, scalars are unchanged.imple… …
113Gunge — as it is known in the British Isles, or slime as it is known in America and other parts of the world is a thick, gooey, runny substance similar in consistency to paint. It has been a feature on many children s programmes for many years around the …
114X-bar/R chart — An X bar/R chart is a specific member of a family of control charts. A control chart is a tool used in quality control, specifically SPC or statistical process control, as originally developed by Walter A. Shewhart at Western Electric in 1924 to… …
115Degrees of freedom (statistics) — In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.[1] Estimates of statistical parameters can be based upon different amounts of information or data. The number… …
116Isotopes of protactinium — Protactinium (Pa) Standard atomic mass: 231.03588(2) u The element has no stable isotopes. However, it has a characteristic terrestrial isotopic composition and thus an atomic mass can be given.Isotopes of protactinium occurring within the… …
