There should be no whitespace between the numeral and the letter X. (Note on character encoding: Although in typography (including Unicode) the letter X and the multiplication sign (×) are distinct characters with differing glyphs, it is a longstanding tradition in engineering drawing that the letter X is interchangeable with the multi sign ...
An inexact differential or imperfect differential is a differential whose integral is path dependent. It is most often used in thermodynamics to express changes in path dependent quantities such as heat and work, but is defined more generally within mathematics as a type of differential form. In contrast, an integral of an exact differential is ...
v. t. e. In the general theory of relativity, the Einstein field equations ( EFE; also known as Einstein's equations) relate the geometry of spacetime to the distribution of matter within it. [1] The equations were published by Albert Einstein in 1915 in the form of a tensor equation [2] which related the local spacetime curvature (expressed by ...
Isothermal processes are of special interest for ideal gases. This is a consequence of Joule's second law which states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. [4] Thus, in an isothermal process the internal energy of an ideal gas is constant. This is a result of the fact that in an ideal gas ...

Δ-DOR navigation has been used by number of NASA planetary missions. Other space agencies have also used the technique, on missions such as: ESA used a Δ-DOR system for Venus Express' orbit insertion in April 2006 and to Rosetta's Mars swingby in February 2007. The technique was also used in guiding the ExoMars Trace Gas Orbiter during its ...
