What it is to be a Substance? and What it is to Exist? We need to establish knowledge about the man and the world on a firm basis and the information it provides must be tested for its accuracy and consistency with an external reality. We have to make the fundamental distinction between the living and the non-living matter. The scientific advances of the 19th and 20th centuries reinforced the materialistic position concerning the basic similarity of organic living and inorganic physical matter. The man is viewed as a product of natural evolution and is thought to be subject to the same laws of Physics and Chemistry or mechanistic principles.
We need a methodology to study philosophy and to understand philosophical statements. Logical Positivism, also known as Scientific Empiricism aims to clarify concepts in both everyday and scientific language. It describes analysis of language as the function of philosophy. This analysis of language and of concepts is important to understand questions of belief and ideology which affect what we think we ought to do individually and socially. I would use this method of ‘Applied Philosophy’ to analyze the concept of Spiritual Optics, the Spiritual Connection between Energy and Life. The Laws of Thermodynamics are important unifying principles of Biology. The First Law of Thermodynamics, also known as the Law of Conservation of Energy, states that Energy can neither be created nor destroyed. Spiritual Optics accounts for the capacity of photoreception and the term Spiritual Light refers to the creation of Light by God to begin the designing of Matter.
WHOLE DUDE – WHOLE DESIGNER – PHOTOCHEMISTRY:
Photochemistry is the study of chemical processes that are exclusively brought about by the interaction of light with matter. The term design describes the action to make a plan, a pattern and carry out the execution by artistic arrangement in a skillful way. Artists, Designers, and Architects are persons who make plans, patterns, the artful scheme for the arrangement of parts, the details, the form, the substance, the color, etc., so as to produce an artistic unit. The study of Photochemistry helps us to recognize the artistic work of a Whole Designer, a Whole Architect, and a Whole Artist who uses Light, Matter, Color, Space, and Time to create living systems which are interdependent, interrelated, and interconnected. The existence of two major systems of Life, plants, and animals is perfectly synchronized and each performs its living functions to complement the living functions performed by the other. Photochemistry establishes the fundamental basis for this spiritual relationship among the living systems. I am pleased to narrate the story about Photochemistry sharing the images of a number of chief players who contributed to the understanding of the design that formulates the interaction between the Laws of Physics, Chemistry, and Biology to generate this amazingly wonderful artistic unit called planet Earth which provides the home to all living things.
THE LAW OF PHOTOCHEMISTRY:
Grotthuss – Draper Law of Photochemistry: Light must be absorbed by a chemical substance in order for a photochemical reaction to take place. Photochemical reactions are chemical processes initiated by the absorption of energy in the form of visible, infrared or ultraviolet radiation. Johann Heinrich Schulze discovered in 1727 that silver nitrate darkens upon exposure to light. The darkening of silver salts is a phenomenon known since the 16th century and possibly earlier and the effect of light on chemical substances was not understood. The art and science of Photography is based on a photochemical process, the action of light on grains of silver chloride, or silver bromide.
Heinrich Rudolf Hertz who expanded James Clerk Maxwell’s electromagnetic theory discovered the Photoelectric Effect in 1887. His research contributed to the development of radio, television, and radar.
THE PHOTOELECTRIC EFFECT:
Photoelectric effect describes the emission of electrons by substances when light falls on their surface. Light energy is transferred in discrete packets, or photons. The energy of each photon is equal to the frequency of the light multiplied by Planck’s Constant “h”. Light imparts energy to a charged particle when one of its photons collides with the particle. In a photochemical process, one atom or molecule absorbs a single quantum of light energy called photon. The immediate consequence of the absorption of one photon by one atom or molecule is called the primary photochemical process. The basic process by which light is absorbed by matter was first proposed by Albert Einstein (1905). His Theory of Light has established that a beam of light is a beam of photons, or quanta (energy packets) of electromagnetic radiation.
When a quantum of light energy (a photon) is absorbed by a molecule, the direct consequence of this interaction is that the molecule is raised to an electronically excited state. The electronically excited state can be viewed as a molecule in which the distribution of the electrons about the atoms that compose the molecule is changed relative to the normal, or ground state of the molecule. Because the electronic distribution affects such properties as bond strengths and molecular geometry, many changes can take place in an electronically excited state that may not occur in the normal, or ground state. The consequences of the absorption of light by a chemical molecule and the subsequent formation of an electronically excited state can be grouped into two main classes; 1. Physical processes, and 2. Chemical processes. In a Photophysical process, a molecule undergoes no direct change in its chemical identity. Examples: Fluorescence, Phosphorescence, and the Photoelectric Effect. In Photochemical processes some change takes place in the bonding arrangement of the atoms in the molecule. Simple photochemical reactions involve the breaking or rearranging of a chemical bond, or both. Visible light and Ultraviolet light are intrinsically energetic enough to break several types of chemical bonds. Photochemistry differs from most other aspects of Chemistry in one regard. If an atom or molecule absorbs energy from a beam of light, it gains far more energy than it ever could by other methods; eg. from ordinary heating. Consequently, photochemical processes are sometimes extremely efficient for the conversion of energy from light into Chemical energy.
The most important photochemical process for living systems is the process of Photosynthesis.
Photoelectric Cell or Photocell is a device whose electrical characteristics vary when light is incident upon it. Three different kinds of Photoelectric Cells exist that use the three different forms of the Photophysical reaction called the Photoelectric Effect. 1. The Photoconductive Cell, known as a Photoresistor is the sensor that scans codes on grocery items in Supermarkets at Checkout Counters.
2. The Photoemissive Cell; Phototubes, “Electric Eyes” that trigger the automatic opening of doors are examples of the Photoemissive Cells.
3. The Photovoltaic Cell used in Fiber Optics technology, and the Solar Cells are common examples of Photovoltaic Cells which convert light energy into electric energy. For Solar Cells, Solar Energy, or Sun is the source of light and it has several applications.
Photochemical reactions that play a vital role in biological systems are called Photobiological processes. Photochemistry establishes relationship between the laws of Physics, and Chemistry with the living functions to synchronize the interactions between Light and Matter that is important for Life to exist on planet Earth.
Green plants with Chlorophyll pigment trap light energy, and transform it into chemical energy and use it in the process described as Photosynthesis. It is a creative mechanism to transform one form of energy into a different form of stored chemical energy that can be further used to create new forms of matter called organic molecules that are not present in nature. These organic molecules come into existence because of the activity of living things. It shows the intent of a designer to use energy, and matter to create the visual, sensory effect.
Who is the Artist? Who is the Designer?
No single function can explain the coloration of living things. We need a comprehensive theory that predicts the lines and patterns of coloration of plants and animals. An artist’s palette containing only three properly chosen colors is entirely adequate under most circumstances to produce the various visual effects of color that is observed. The optical mechanisms involved in the production of color are complex. Coloration is a dynamic and complex characteristic and the term must be clearly distinguished from the term ‘color’ which only refers to the spectral qualities of emitted or reflected light. It is apparent that plants, and animals have no cognitive abilities to produce the coloration by which they are recognized. However, the coloration displayed gives us a clue about the nature of the “Whole Artist” who could be using imagination, has feelings for the forms created and seeks satisfaction from the visual effects that he produced. If man has the ability called visual perception, he must use the ability to visualize the “Whole Artist” who is at work. I ask my readers to give attention to the three dimensions of Color Perception. These are, 1. The Designer or the Artist, 2. The Object of Perception, and 3. The visual capacity of the Viewer.
