These three layers, the endoderm, the ectoderm and the mesoderm, are called the primary germ layers. After gastrulation, the cup-like embryonic stage that contains at least two distinct germ layers is called the gastrula.n mammals, gastrulation is achieved in a very different way. This is because the outer layer of the mammalian blastocyst, which is roughly equivalent to the blastula, becomes the mammalian placenta and is not available to create the primary germ layers of the embryo.
I think the Wolfram System is the term now used to describe what we currently think of as Mathematica. The term Wolfram Language is the language in which you write code in the Wolfram System, or what we currently call (loosely) the Mathematica language, rather than the whole shebang - FrontEnd, Kernel, etc.. Still, that's just me guessing - I know nothing. :) â cormullion Nov 26 '13 at 20:18.
A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.he first programming languages designed to communicate instructions to a computer were written in the 1950s. An early high-level programming language to be designed for a computer was Plankalkuel, plankalkÃ¼l developed for The German z3 By Konrad zuse between 1943 and. 1945, however it was not implemented until 1998 and. 2000
