Physics and the Real World

Physics and chemistry underlie the nature of all the world around us, including human brains. Consequently some suggest that in causal terms, physics is all there is. However we live in an environment dominated by objects embodying the outcomes of intentional design (buildings, computers, teaspoons). The present-day subject of physics has nothing to say about the intentionality resulting in exi...

Real physics in complex spacetime

Since introducing electromagnetic wavelets in 1994, I have been intrigued by two related questions: (a) what are the sources responsible for their emission and absorption, and (b) can these sources be realized and used to launch and detect the wavelets? In principle, it should be easy to find the source for a known solution of a linear system. However, these wavelets are pulsed-beam propagators...

Real-Time Physics-Based Fight Characters

In this paper, we present a practical physics-based character system for interactive and dynamic environments. It uses a number of straightforward, computationally efficient, and conditionally stable techniques to produce responsive, controllable, and interactive character avatars. We describe different physics-based simulation techniques to produce interactive animations and present a detailed...

Second Life Physics: Virtual, real, or surreal?

Science teaching detached itself from reality and became restricted to the classrooms and textbooks with their overreliance on standardized and repetitive exercises, while students keep their own alternative conceptions. Papert, displeased with this inefficient learning process as early as 1980, championed physics microworlds, where students could experience a variety of laws of motion, from Ar...
