The Piano Quintet in G minor, JS 159, is a five-movement chamber piece for two violins, viola, cello, and piano [3] written in 1890 by the Finnish composer Jean Sibelius. When composing the piece, Sibelius replaced the original Movement IV (marked Vivace ) with a scherzo ( Vivacissimo ); the earlier Vivace is extant.
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

This is the beginning of the Prelude from the Suite for Lute in G minor, BWV 995 (transcription of Cello Suite No. 5, BWV 1011). Musical notation is any system used to visually represent music. Systems of notation generally represent the elements of a piece of music that are considered important for its performance in the context of a given ...
Potential energy with respect to gravity, close to Earth, per unit mass: gh, where g is the acceleration due to gravity (standardized as ≈9.8 m/s 2) and h is the height above the reference level (giving J/kg when g is in m/s 2 and h is in m).
The Walter Minor is a family of four- and six-cylinder inverted inline air-cooled engines, developed under auspices of ing. Šimůnek and used on light aircraft. First produced in 1929, the Minor engines' family has an advanced design for the period and sports steel cylinders, aluminum heads and overhead valves, with identical bore and stroke of 105 mm (4.1 in) and 115 mm (4.5 in), respectively.
Peak ground acceleration can be expressed in fractions of g (the standard acceleration due to Earth's gravity, equivalent to g-force) as either a decimal or percentage; in m/s 2 (1 g = 9.81 m/s 2); [7] or in multiples of Gal, where 1 Gal is equal to 0.01 m/s 2 (1 g = 981 Gal).
The gravitational constant appears in the Einstein field equations of general relativity, [4] [5] + =, where G μν is the Einstein tensor (not the gravitational constant despite the use of G), Λ is the cosmological constant, g μν is the metric tensor, T μν is the stress–energy tensor, and κ is the Einstein gravitational constant, a ...
The lower limit for "heavyweight" was established in 1948 at 81 kg. When a new limit of 91+ kg was established in 1984, the name "heavyweight" was kept by the 81+ kg class, and the 91+ kg class was named "super heavyweight", a name not currently used in professional boxing. Classes are as follows: [16]
