The Constant Gardener is a 2005 drama thriller film [2] directed by Fernando Meirelles.The screenplay by Jeffrey Caine is based on John le Carré's 2001 novel.The story follows Justin Quayle (Ralph Fiennes), a British diplomat in Kenya, as he tries to solve the murder of his wife Tessa (Rachel Weisz), an Amnesty activist, alternating with many flashbacks telling the story of their love.
The cosmological constant was originally introduced in Einstein's 1917 paper entitled “The cosmological considerations in the General Theory of Reality”. [2] Einstein included the cosmological constant as a term in his field equations for general relativity because he was dissatisfied that otherwise his equations did not allow for a static universe: gravity would cause a universe that was ...
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
"Man of Constant Sorrow" (also known as "I Am a Man of Constant Sorrow") is a traditional American folk song first published by Dick Burnett, a partially blind fiddler from Kentucky. It was titled "Farewell Song" in a songbook by Burnett dated to around 1913. A version recorded by Emry Arthur in 1928 gave the song its current titles.
First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.
The time constant is related to the cutoff frequency f c, an alternative parameter of the RC circuit, by = = or, equivalently, = = where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in Hz.
Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10-23 J K-1.The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule).
The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later showed that its value could be calculated from more fundamental constants according to his model of the atom.
