The parallel computing features of Mathematica entirely replace the Parallel Computing Toolkit that was available up to Mathematica Version 6. As stated in the Introduction, ...

By default, any interface definition executes within a single thread, and since currently GUIKit` definitions execute at runtime as Java components, this means that execution ...

The functions defined in Music` allow you to make conversions between cents and hertz, and play scales in one of the common tuning systems, or in a user-specified tuning ...

The functions defined in ResonanceAbsorptionLines` allow you to efficiently search through an atomic data table for resonance absorption lines. Other functions give ...

DateListPlot[{{date_1, v_1}, {date_2, v_2}, ...}] plots points with values v i at a sequence of dates.DateListPlot[{v_1, v_2, ...}, datespec] plots points with dates at equal ...

EllipticF[\[Phi], m] gives the elliptic integral of the first kind F(\[Phi] \[VerticalSeparator] m).

NMaximize[f, x] maximizes f numerically with respect to x.NMaximize[f, {x, y, ...}] maximizes f numerically with respect to x, y, .... NMaximize[{f, cons}, {x, y, ...}] ...

NSum[f, {i, i_min, i_max}] gives a numerical approximation to the sum \[Sum]i = i_min i_max f.NSum[f, {i, i_min, i_max, di}] uses a step di in the sum.

RealDigits[x] gives a list of the digits in the approximate real number x, together with the number of digits that are to the left of the decimal point. RealDigits[x, b] ...
