The package sciencestuff.sty provides shortcuts for commonly inserted commands in scientific texts.
Included Packages
Together with new commands, the package also automatically includes:
amsmath, amssymb, amsfonts for mathematical symbols and fonts,
dsfonts for improved numerical sets,
upgreek for upright Greek letters,
physics for common physics-related objects,
siunitx for SI units of measurements,
cleveref for improved citations.
Commands
This is a collection of commands which can be used:
\1 for the identity matrix,
\N, \Q, \R, \Z for numeric sets.
\c<capital-letter> for calligraphic letters,
\r<capital-letter> for romanic letters,
\f<capital-letter> for Gothic letters.
\O{<num>} for orthogonal groups,
\SO{<num>} for special orthogonal groups,
\U{<num>} for unitary groups,
\SU{<num>} for special unitary groups,
\GL{<num>}{<field>} for general linear groups,
\SL{<num>}{<field>} for special linear groups.
\ipd{<letter>} can be used for inline partial derivatives (e.g. \ipd{u} is equivalent to \partial_u).
As \dd[<num>]{<letter>} can be used to print \mathrm{d}^<num> <letter>, \dss[<num>]{<letter>} can be used to print \mathrm{d}<letter>^<num>.
\zeroinfint{<letter>} is used for integrals from 0 to +\infty in \dd{<letter>},
\infzeroint{<letter>} is used for integrals from -\infty to 0 in \dd{<letter>},
\infinfint{<letter>} is used for integrals from -\infty to +\infty in \dd{<letter>},
\finiteint{<letter>}{<low>}{<upp>} is used for integrals from <low> to <upp> if \dd{<letter>}.
