In 1887, two American scientists by the name of Michelson and Morley devised a highly sensitive experiment that could measure the speed of light in the direction of motion of the earth. Almost every scientist at the time, including Maxwell himself, presumed that Newton was correct, and that Maxwell's equations were incomplete and needed to be modified. There was no accounting for a speed of light that was any different than what his equation predicted.
But Maxwell's equations seemed to indicate that light has just one speed, c.

The measured speed should be the speed of the person, PLUS the speed of light. What would the speed of light be then? According to Newton, this moving observer should measure a different speed, than someone who was not moving. The question was what would be the measured speed of light, if the person measuring it was moving, for example, a person moving with the spin of the earth. And his theory predicted what the speed of this wave is, so it predicted the speed of light, which is about 300,000 km/s or 300 million meters per second. Maxwell had shown that light was a propagating wave - a disturbance in the electromagnetic field - a changing electric field continually giving rise to a changing magnetic field which in turn gives rise to a changing electric field again, leading to a self-propagating electromagnetic wave. In the late 1800’s, scientists had recognized that there was an inconsistency between two theories Newton's laws of motion, and Maxwell's equations describing electricity and magnetism. Let’s Discuss…!!! How did the idea of time as a dimension come about?
In fact, these 4 dimensions can describe any event in the universe.īut how did time become a dimension. With these 4 coordinates, you could rendezvous with anyone anywhere in the universe. These are the 4 dimensions of the universe - three spatial dimensions and one time dimension. He or she would have to know what time they were to meet you at that precise location. Why? because you did not give him one more crucial piece of information - the time.
Would this be enough information for two people to meet? Well, if you showed up at that location, there is no guarantee that you would meet your friend. As far as we are aware, this paper reports the first interactive system with force-feedback that provides "4D haptic visualization" permitting the user to model and interact with 4D cloth-like objects.If you wanted to meet a friend at any possible location on earth, you would need them to give you a precise longitude, latitude, and altitude. By physically modeling the correct properties of 4D surfaces, their bending forces, and their collisions in the 3D haptic controller interface, we can support full-featured physical exploration of 4D mathematical objects in a manner that is otherwise far beyond the experience accessible to human beings. Building on the reduced-dimension 2D editing tool for manipulating 3D shapes, we develop the natural analogy to produce a reduced-dimension 3D tool for manipulating 4D shapes. By combining graphics and collision-sensing haptics, we can enhance the 2D shadow-driven editing protocol to successfully leverage 2D pen-and-paper or blackboard skills. We begin with a teaching tool that uses 2D knot diagrams to manipulate the geometry of 3D mathematical knots via their projections our unique 2D haptic interface allows the user to become familiar with sketching, editing, exploration, and manipulation of 3D knots rendered as projected imageson a 2D shadow space. In particular, by taking advantage of physically reactive 3D shadow-space controllers, we can transform the task of interacting with 4D objects to a new level of physical reality. Just as we can work with two-dimensional floor plans to communicate 3D architectural design, we can exploit reduced-dimension shadows to manipulate the higher-dimensional objects generating the shadows.
