|  | | In cosmology, dark energy is a hypothetical form of energy which
permeates all of space and has strong negative pressure. According to
the theory of relativity, the effect of such a negative pressure is
qualitatively similar to a force acting in opposition to gravity at
large scales. Invoking such an effect is currently the most popular
method for explaining recent observations that the universe appears to
be expanding at an accelerating rate, as well as accounting for a
significant... | Size: 539.2 KB License: Freeware

|  | | The physic of the real world can be formulated into mathematical form using differential equations. Differential equation and systems of differential equations are the natural language trough we can describe any real devices like electronic circuit, automatic controls, elettro-magnetic wave emission or any other engineering problems. The purpose of OpenDDPT project is to build a software that can aids people to build automatically these control devices. The strategy used by this software is... | Size: 2.2 MB License: Freeware
