The rapid development of technology has allowed computer simulations to become routinely used in an increasing number of fields of science. These simulations become more and more realistic, and their energetic efficiency grows due to progress in computer hardware and software. As humans merge with machines via implants, brain-computer interfaces and increased activity involving information instead of material objects, philosophical concepts and theoretical considerations on the nature of reality are beginning to concern practical, working models and testable virtual environments. This article discusses how simulation is understood and employed in computer science today, how software, hardware and the physical universe unify, how simulated realities are embedded one in another, how complicated it can get in application, practical scenarios, and the possible consequences of these situations. A number of basic properties of universes and simulations in such multiply nested structures are reviewed, and the relationship of these properties with a level of civilizational development is explored.

Perception of time is an important ability: timing plays a crucial role in accomplishing various real-life tasks. This work concerns judgments made about short temporal intervals. The main goal was to implement the well known Scalar Timing Model (STM) as an artificial neural network. The implementation of the STM resolves to mapping the architecture of the model into an artificial neural network. Another direction of experiments concerns the pacemaker and distribution of generated pulses in time. Manipulation of pulse distribution in time helps in explaining basic, empirical regularities concerning perception of time, and the relation between the stimulus and its sensation. The STM implementation described in this paper models the time-order error (TOE), a phenomenon often reported in experiments on living organisms. This research is a starting point for further wide-scale analysis of human time perception on psychological, psychophysical and biological levels.

This paper concerns evolution of three-dimensional stick agents in a simplified ski-jumping task. Both body morphologies and control systems are optimized. Evolutionary processes are performed in a range of conditions: the air drag and the friction of the ramp varies. Qualitative and quantitative analyses are presented that show how jump distance, jump height, and flight trajectory depend on environmental conditions. Jumping and landing strategies are investigated, and the most interesting evolved behaviors are reported.
