Scientific and educational software



We do not believe, we estimate probabilities instead. Most possible, a principal of natural selection can be applied to any phenomenon without any exception. Human being can be considered as a robot made on the base of organic materials, society is an analog of anthill, God is a conglomerate of dreams (there no direct sense in this statement about God but one can project his own subconscious into). In such philosophy knowledge is a model inside brain about objective world that sane people consider exists independently from us. We are part of it of course that creates paradox appearance constant attempts by word to understand itself via human. Attempts these billion times are being failing with next dead. Pity it is.

In some way creation of computers is an ultimate resolution by universe of defect in material selection for intelligent creatures like we are. Silicon memory has much more longevity compare to organic walking and talking colloids so they have best chance to succeed us in mortal competitive game of evolution. The choice for us is passive or violent resistance against electronics or collaboration. We give up on any insurgence against progress (maybe to define it on some privilege terms should be such lack).

A development of objective model of the word is responsibility of science. Up to very lately science was what scientists do. If close all universities and wait several generations science will be completely disappeared industry. Nobody will be able to understand content of scientific journals, how to operate instruments, what charts are mean. One should know big part of answer to be able ask an intelligent question. But if textbooks and articles will be accompanied by software programs made in intuitive interface style scientific knowledge could be finally separated from priests of science.

That is what we do not believe. That is what we are doing.
