Know some special word in mathematics like “What is Gyroscope? What is Fathom? What is Hamming codes?”

What is commensurable?

Measurable in terms of the same units.  For example, a 20-centimetre length is commensurable with a 1-meter length as both can be measured in centimetres, but the length of a side and that of a diagonal of a square are not commensurable.

What is Greenwich Mean Time?

The sun transits through all points on a meridian, hence every point on an E-W line has a different noon time, which gives the local time. The earth may be thought of as divided in a zone each with a standard time based on the local time of some meridian crossing the zone. Thus, each hour covers a time extending across 15⁰ of longitude. Noon at Greenwich is taken as noon in the British Isles, Portugal, Morocco and a part of West Africa. Noon in central Europe is at 1.00 pm. G.M.T.

 What is Gyroscope?

A gyroscope is a rotating object that tends to maintain a fixed orientation in space. For example, the axis of the rotation earth always points in the same direction towards the Pole Star. A spinning top or a cyclist is stable when moving at speed because of the gyroscopic effect.

What is Parseval’s theorem?

The theorem of Fourier analysis states that Bessel’s inequality holds as equality for a square-integrable function. The term is also applied to extensions of this to any complete orthonormal sequence in a Hilbert space, named after the French mathematician, Marc Antoine parseval de Chenes, who had to flee France after he publicised poems critical of Napoleon.

What is Fathom?

A unit of length is used to measure the depth of water. It is equal to 6 feet (1.8288 m)

What is goodness to fit?

The extent to which observed sample values of a variable approximate the value derived from a theoretical distribution.

What are Hamming codes?

A class of efficient error correcting codes, usually binary codes, that allow the recipient to diagnose and correct a certain number of transmission errors per word, with the change of a high proportion of errors being negligible.

What is a Heuristic?

It is based on trial and error, for example, some techniques in iterative calculations.

What is Histogram?

A statistical graph that represents, by the height of a rectangular column, the number of times that each class of result occurs in a sample or experiment.

What is Hypocycloid?

A curve is described as a point on the circumference of a circle as it rolls around the inside of another fixed coplanar circle. The form depends on the ratio of the radii of the circles.
