Abstract
Current trends in informal science learning tend to place more emphasis on science centers as tools to bridge the technological gap for their visitors (Salmi, 2003; Sandifer, 2003). In line with compelling evidence in the multimedia literature, which shows that technology-based environments do provide good instructional support for meeting learning needs (Kim, 2006; Lim, Nonis, & Hedberg, 2006), it would be useful to investigate the potential of technology-based exhibits at science centers to create new multisensory experiences for learning science topics in a way that is different from traditional methods of teaching. This can provide pointers for schools to see how such attractions can be used to assist or complement the formal science learning in schools. The principal objective of this research is to investigate the effectiveness of technology-based exhibits in promoting affective learning outcomes among students of mixed ability visiting a science centre. The chosen exhibit is the CAVE (cave automated virtual environment), a supercomputerbased multimedia system.

Multi-Threaded Architectures: Evolution, Costs, Opportunities
A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. Supercomputers are used for highly calculation-intensive tasks such as problems involving quantum physics, weather forecasting, climate research, molecular modeling and physical simulation.

High Performance and Grid Computing Developments and Applications in Condensed Matter Physics
Is a computer system capable of executing large number of operations, comprising a massive number of processors and large shared or distributed memory. The processors are running in parallel and are able to exchange the data, thus making possible to achieve high computing power, which is usually measured in the number of floating point operations being executed in one second. The required computer power for a system to be designated as a supercomputer is time-dependent, and is usually defined through a list of most powerful systems in the world, such as Top500 (top500.org), where only a limited number of systems (e.g. first 500) at any given time are considered to be supercomputers. As of 2013, petaflops-capable systems are classified as supercomputers, and in the coming years this will shift towards exaflop-capable systems.
