Summary/Abstract: Science simulation appears in physics, today, as a third, new scientific way in the Western thought, beside the theory and the experiment. Monte Carlo simulations help building state of the art detectors, to make both correction of acceptance of the detector and better physics interpretation of the results, and particularly they are useful for tracking and identification (PID Particle Identification) of particles emerging from the collisions. Simulation techniques of particles head-on collisions and particles interactions with a various detectors and/or detection systems, are generally developed by using a famous CERN computer library (a main tool is the GEANT code). Simulations are related both to the complex detector systems and associated trigger and electronics, with a computer system for acquisition, reading and storing of the data, but to be necessary based on the clear physical picture or method. Situation is more precisely illustrated by the example of ATLAS experiment! That is one of the greatest experiments of the contemporary Standard Model of elementary particles and cosmology, to be executed in the 2006 when a Large Hadron Collider (LHC) at CERN would be probably commissioned. ATLAS aims to discover Higgs bosons, a particle which plays a key role in the framework of the Standard Model. Real or physical world in simulations does not remain »thing in itself« in the Kantian original meaning anymore, but rather thing whose essence is apprehended in the more comprehensive way by simulation than by ordinary senses. A »sensation«, either of the Locke's or Kantian type, was generally broadened and went beyond by the contemporary information technology as a new ontology. In this way simulation started to play a key role in ontology and epistemology, i.e. theory of knowledge of the philosophy assigned to the expanding frontier of the contemporary physics. The Einsteinian ideal of the divine origin to the natural laws in the theory and experiment seems to be overthrown by the development on the third avenue of simulation. A probabilistic and statistic nature of its results ascribing disputandum est characteristic to the data of simulation against the absoluteness and even divine origin of the physics laws and equations.
