  2. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.

  3. Petascale computing - Wikipedia

    en.wikipedia.org/wiki/Petascale_computing

    Petascale computing refers to computing systems capable of performing at least 1 quadrillion (10^15) floating-point operations per second (FLOPS).These systems are often called petaflops systems and represent a significant leap from traditional supercomputers in terms of raw performance, enabling them to handle vast datasets and complex computations.

    The long and short scales are two powers of ten number naming systems that are consistent with each other for smaller numbers, but are contradictory for larger numbers. [1] [2] Other numbering systems, particularly in East Asia and South Asia, have large number naming that differs from both the long and short scales.

    en.wikipedia.org/wiki/Pentaerythritol_tetraacrylate

    Pentaerythritol tetraacrylate (PETA, sometimes PETTA, PETRA) is an organic compound. It is a tetrafunctional acrylate ester used as a monomer in the manufacture of polymers . [ 1 ] As it is a polymerizable acrylate monomer, it is nearly always supplied with an added polymerisation inhibitor , such as MEHQ (monomethyl ether hydroquinone).
