The center of our galaxy is about 27,000 light years away in the direction of the constellation Sagittarius.  That isn't a large distance on astronomical scales, but it is hidden by gas and dust so we can't observe it in visible light.  We can, however, observe it at infrared and radio wavelengths,

In the mid-1800s, astronomy faced a serious problem.  No one knew how the stars shone.  Now a little mystery never hurt anyone, but in this case it was deeply perplexing.  By this time we had a solid understanding of energy, and that energy is conserved.  That is, energy must come from somewhere, and it

In Medieval Europe, the physical universe could be divided into two parts: the Earth and earthly events (chaotic and temporary) and the heavens (structured and eternal).  That's a bit of an over simplification, but the idea was that the Earth and heavens were governed by different rules.  In the heavens the stars were fixed and eternal.  The motion of the planets were thought to move in

At the end of the 1800s we finally knew how the universe worked.  Newton’s laws of motion and gravity had been studied for 200 years, and had become the pinnacle of scientific precision.  James Clerk Maxwell had unified the electricity, magnetism and light into a single elegant theory, and

Introduction

Robugs are 'robotic bugs' whose behaviour is controlled by user-designed circuits. It will be an educational tool as much a game, and provide a more complex/richer simulation than other similar programs. The project is being written in Java (JDK 1.5/Java3D 1.3).
