ON Maxwell's theory, lines of electric force which are not anchored to charged particles travel at right angles to themselves with the velocity of light. A circular line of force travelling at right angles to its plane would fulfil this condition and would travel unchanged without loss of energy; it would thus possess one of the properties of the ...

Abstract This chapter reconstructs a hexaemeral theory of light from a combined reading of the sources. Through the causal interlink of fire and light, hexaemeral light is theorized as the purest kind of fire. The chapter explores the language and physical properties of fire that explain luminosity: the light ray, its liminal ...

AbstractSimulating natural light is an interesting subject in computer graphics. Using the principles of meteorology, we build a sphere cap light source model. Unlike existing illumination or light source models, we consider the effects of both the ratio of direct light to diffuse light and the position of the sun under different weather conditions. We

A new light on the nature of light
Physics Essays, 2012The Quantum Theory and Special Relativity stand apart because their authors were admittedly unclear about Wave-quantum Unity of light and light propagating medium. A single experiment shows wave-quantum unity for low intensity light and moving electrons.

The question ‘is light a ray, a wave or a particle?’ has long fascinated philosophers and has intensified since the concept of the photon first emerged at the beginning of the twentieth century. The pragmatic answer to the question is ‘it depends what you are looking for’ and is really about how best to conceptualise light in particular circumstances ...

Light, the first thing as human beings open eyes, is so important to everyone of us. It is also the most mysterious in the universe about which we have seemingly known a lot, but in fact we still know very little. From Isaac Newton's particle theory to Christiaan Huygens' wave theory then Albert Einstein's wave-particle duality, no one has ever told us

It is staggering to consider the degree to which civilization has evolved in the approximately 90 years since Niels Bohr’s ad hoc quantization of atoms based on experimentally measured line spectra The changes that have occurred, including the growth of our knowledge of the micro and macro material worlds and the emergence of new technologies, have ...
