Solar Calculations Math Tutorial

Solar Calculations Math Tutorial
for Solar Energy Power Systems
Electricity can be a mystery to folks who have never had any experience working with it, or for folks who took physics in high school (that's me) and can't remember much of anything other than that the battery made the light bulb glow.
Basic electric calculations for off grid solar applications are not that hard, but you have to know the terminology.  Here it is.  Don't quit now, it's really pretty easy, but you have to learn the vocabulary for it to make sense.
Amps
Amps is a measure of energy flow, measured in electrons moving per second.  The amount of Amps represents the amount of charge flowing past a point in a particular time period.
Volts
Volts is a measure of the force of the moving electrons.  It's the pressure which causes electrical current to flow. It is also used to describe the amount of energy stored, like a 12 volt battery.
Watts
Watts is a measure of power.  It describes the amount of energy converted by an electrical circuit.
Ohms
Ohms is a measure of electrical resistance.  It you have a wire with two conductors, like a lamp cord, and connect one conductor to the positive and the other to the negative pole of a 12 volt battery (like jump starting a car), the smaller the wire diameter and the longer length of the wire the greater the Ohms, which causes the Volts delivered to decrease.  An increased resistance measured in Ohms causes a reduction in current aka Volts.
The Good Old Garden Hose Example
Get your garden hose and turn on the water so that it is flowing at the rate of a couple of gallons a minute, so that you could fill up a 5 gallon bucket in 2-3 minutes.
The rate of flow of the water, which is pretty slow, is equivalent to Amps.  The lower the flow the lower the amps.
The force of the water coming out of the hose is the Volts.  The lower the force, the lower the volts.
The power (energy) of the water coming out of the hose is Watts.  Put your thumb over the end of the hose and see how far you can squirt.  The harder you squeeze the farther you can squirt?  The water flow is still a couple of gallons per minute.  In the same way, if you increase the Volts, a small amount of Amps can turn into a lot of Watts.
If you link together 2 or 3 or 4 garden hoses without changing the setting on the faucet, what you will see is that the rate of flow goes down because the resistance of the water passing though the hose reduces the flow.  This same effect is measured in Ohms in electrical circuits.
Solar Calculations Math
All of these electrical units of measure are used together to determine the Volts, Amps and Watts for any particular solar electric application.  I am not going to talk about Ohms or Ohms Law.  Ohms is not important for calculating solar component sizing.  Ohms IS important when you start looking at the available Volts and wire sizes and the distances between components like batteries, solar panels, charge controllers and inverters.  The lower the Volts and the greater the distance traveled, the bigger the wire that is needed.
Volts x Amps = Watts
This is the starting point for doing the math.
Convert Watts to Amps: Amps = Watts / Volts  (slash = divide)
12 Watts / 12 Volts = 1 Amp
Convert Amps to Watts:  Watts = Amps x Volts
1 Amp x 12 Volts = 12 Watts
Convert Watts to Volts:  Volts = Watts / Amps
12Watts / 10 Amps = 12 Volts
Convert Volts to Watts:  Watts = Amps x Volts
12 Amps x 12 Volts = 144 Watts
Energy Measurements Over Time
When you are trying to figure out what size solar panels you need, and how much battery storage, and what size charge controller or inverter you need for any particular solar energy application, the time that the sun shines on your panels, the time between sunny days (cloudy weather), the time that you what to be able to operate whatever you are going to power with your solar energy - everything is about time. 
So, watts and amps are measured by time for any given voltage.  The voltage of your off grid system is a given based on what you decide - you are going to have a 12 volt system, or a 24 volt system, or a 48 volt system based on the batteries you decide to use.

and energy inflow from your solar panel.
A Simple Load Analysis
I have two 10 watt 12 volt LED lights I want to operate for 4 hours per night.  10 watts x 2 x 4 hours = 80 watt-hours.
80 watt-hours divided by 12 volts = 6.67 amp hours.  Because we can only use half the energy in a lead acid battery without harming the battery, the minimum battery size is 6.67 amps x 2 = 13.34 amp hours.
I want my system to be reliable if we have four consecutive days of cloudy weather, 4 days of autonomy x 13.34 = 53.36 amp hours for the battery.  Sun Xtender makes a 56 amp hour AGM battery, PXV-560T.
This installation is in a location that gets 5 hours of full sun (insolation) per day.  To recharge the battery for one day of use we need 13.34 amps in 5 hours = 2.67 amps from a 12 volt solar panel.  Most load calculations include a discount factor for the inefficiency of recharging the battery.  20 percent is typical.  2.67 / 0.8 = 3.34 amps.  We have a 60 watt solar panel that has an Imp (amps maximum power point) of 3.49.  Look at the 60 watt panel top of the page.
The 60 watt solar panel has a short circuit amp rating (Isc) of 3.86 amps.  3.86 x 1.25 = 4.83.  I can use a 5 amp or larger charge controller with this panel to charge the battery.  If I want to make sure I am getting the best efficiency available for charging the battery, I would use a small MPPT charge controller like the Genasun 5 amp for lead acid.
Summary
Solar energy math calculations for system sizing can be done with a simple calculator using the basic formulas shown here.
If you want to see an example already in the website, read my page about CPAP battery backup emergency solar power.
When you calculate your loads, you will quickly see the advantage of using the most energy efficient devices you can find, like our SunDanzer solar refrigerators and freezersfor example.  High efficiency refrigerators and other appliances like Vari-Cyclone super energy efficient ceiling fansPico portable LED lights and other electrical devices used around the house are less expensive than solar electric components.  If you can downsize your loads through efficiency, your solar system will be less costly and easier to justify from a return on investment perspective.

Successful Off Grid Solar

Successful Off Grid Solar 

So You Think You Want to Go Off Grid?
The common question asked by the uninitiated, without providing any other significant details, is “What will it cost to take my house (cabin, cottage, etc.) off grid?”
There is no pat answer to the question. From my own experience of living off grid for more than 5 years, my advice is to think very carefully about your willingness to adapt your energy consuming behavior to the variables of being dependent on sun, wind and in some cases moving water for your energy needs rather than being connected to a seemingly endless supply of grid electricity created by burning the remains of dinosaurs and their ancient habitat (oil and coal) or the fission of radioactive materials that leave waste with a nasty half-life of 50,000 years or more.
Even the best designed off grid system will experience variables that will require occasional behavior modification whether you like it or not. Sticker shock typically occurs for those who want things to be off grid and just like they have always been. Things are not going to be like they have always been. Reliability of the grid as evidenced by the recent events in India that left 600 million people without electricity is an insight into our energy future.
This being said, as far as I can tell, unless you are a Wall Street robber baron or a banker with friends at the Federal Reserve and Treasury Department, there is no better return on investment in today’s uncertain times than being your own power company. Grid power is not going to get any cheaper as fossil fuel supplies decline. The US solar tax credit and other local incentives help to defray initial investment. Your future cost of electricity is now known, with the main future expense being the replacement of batteries which you can cover through a monthly sinking fund contribution to your savings account that will be significantly less than your current utility bills.
Success is in the DETAILS!
The success of an off grid solar system design begins with details. The size of an off grid solar electric system depends on the amount of power that is required (measured in watts), the amount of time it is used (measured in hours)and the amount of energy available from the sun in available in the location where the system will be installed (measured in solar insolation (sun) hours per day).
As a prospective off grid solar system owner and user, you have control of the first two of these variables. The third variable depends on your location and the weather.
Conservation Saves the Day
Conservation plays a highly important role in keeping down the cost of an off grid solar system. The use of energy efficient appliances and lighting, as well as non-electric alternatives wherever possible, can significantly reduce the size and cost of the system.
There are very few exceptions where conservation is less cost effective than the alternative. Anything that you can operate on low voltage direct current (DC) rather than 115 or 230 volt alternating current
(AC) will make a big difference. 230 volt single phase AC in parts of the world that use 115 volts requires two inverters to make the two legs of 115 that make 230 single phase.
Cooking, Heating, & Cooling
Conventional electric cooking, space heating and water heating equipment use a prohibitive amount of electricity. Electric ranges use 1500 watts or more per burner, so bottled propane or natural gas is a popular alternative to electricity for off grid cooking. A microwave oven has about the same power draw, but since food cooks more quickly, the amount of kilowatt hours used may not be large. Propane, natural gas and wood are better alternatives for space heating.
Good passive solar design and proper insulation can reduce the need for winter heating. Evaporative cooling is a more reasonable load than air conditioning and in locations with low humidity; the results are almost as good. One plus for cooling-the largest amount of solar energy is usually available when the temperature is the highest.
Low voltage ceiling fans, ventilating fans and whole house fans do a remarkable job of creating comfort during both warm and cool weather. We have lived off grid for over 5 years without air conditioning. The ceiling fan over the bed works wonders. Ceiling fans running on low speed circulate heat from the wood stove during the heating seasons.
Lighting
Lighting requires the most study since many options exist in type, size, voltage and placement. The type of lighting that is best for one system may not be right for another. The first decision is whether your lights will be run on low voltage direct current (DC) or conventional 110 volt alternating current (AC). In a small home, an RV, or a boat, low voltage DC lighting is often the best choice. DC wiring runs can be kept short, allowing the use of fairly small gauge wire. Since an inverter is not required, the system cost is lower.
When an inverter is part of the system, a home will not be dark if the inverter fails and the lights are powered directly by the battery. In addition to conventional-size medium-base low voltage bulbs, the user can choose from a large selection of DC LED lights, which have 3 to 6 times the light output per watt of power used compared with incandescent types.
Halogen bulbs are 30% more efficient and actually seem almost twice as bright as similar wattage incandescents given the spectrum of light they produce. High quality LED lights are available for 12 and 24 volt systems.
In a large installation or one with many lights, the use of an inverter to supply AC power for conventional lighting is cost effective. AC LED lights will save a tremendous amount of energy. It is a good idea to have a DC-powered light in the room where the inverter and batteries are in case there is a problem with the inverter.
AC light dimmers will only function properly on AC power from inverters that have pure sine wave output.
Refrigeration
Natural gas or propane powered absorption refrigerators are a good choice in small systems if natural or bottled gas is available. Modem absorption refrigerators consume 5-10 gallons of LP gas per month. They also create heat, good in the winter, not so good in the summer. If an electric refrigerator will be used in a stand-alone system, it should be a high-efficiency type. Some high-efficiency conventional AC refrigerators use as little as 1200 watt-hours of electricity per day at a 70° average air temperature.
A comparably sized Sun Frost refrigerator/freezer uses half that amount of energy and the smallest SunDanzer refrigerator (without a freezer) uses less than 200 watt-hours per day. The higher cost of good quality DC refrigerators is made up by savings in the number of solar modules and batteries required to operate the alternatives.
Major Appliances
Standard AC electric motors in washing machines, larger shop machinery and tools, swamp coolers, pumps, etc. (usually 1/4 to 3/4 horsepower) require a large inverter. Often, a 2000 watt or larger inverter will be required. These electric motors are sometimes hard to start on inverter power, they consume relatively large amounts of electricity, and they are very wasteful compared to high-efficiency motors, which use 50% to 75% less electricity.
A standard washing machine uses between 300 and 500 watt-hours per load, but new front-loading models use less than 1/2 as much power. If the appliance is used more than a few hours per week, it is often cheaper to pay more for a high-efficiency appliance rather than make your electrical system larger to support a low-efficiency load. Vacuum cleaners usually consume 600 to 1,000 watts, depending on how powerful they are, about twice what a washer uses, but most vacuum cleaners will operate on inverters larger than 1,000 watts since they have low-surge motors. There are also battery powered low voltage vacuums that can now be purchased at places like Wal-Mart.
Small Appliances
Many small appliances such as irons, toasters and hair dryers consume a very large amount of power when they are used but by their nature require very short or infrequent use periods. If the system inverter and batteries are large enough, they will be usable. Electronic equipment, such as stereos, televisions, VCR's and computers have a fairly small power draw. Many of these are available in low voltage DC as well as conventional AC versions. In general, DC models use less power than their AC counterparts.
Standby Loads
Electrical appliances and hardware that are “instant on” use electricity whether they are actually on or not.
Looking Back in Time
Before the electrification of North America and elsewhere, there were mechanical alternatives to most of the common appliances used today. Do you really need an appliance for every little thing in your kitchen and your life?
Calculate Your Loads
The last page of this document is a typical loads listing for conventional appliances. This is helpful but not as good as the real thing from your own situation. Details!
Included in the ZIP file is an Excel workbook you can use to determine the total energy in watt-hours per day used by all the AC and DC loads in your system. Save a copy of the original and then use a copy to do your work. Send back the workbook and I will finish the calculations for you.
Calculate Your AC Loads
If there are no AC loads, go to the DC loads section.
1. List all AC loads, amps, watts and hours of use per week in the spaces provided. Multiply watts by hours per day to get watt-hours per day. Add up all the watt hours to determine AC watt-hours per day. Insert more lines if you need to list more loads than the space allows.
2. NOTE: Wattage of appliances can usually be determined from tags on the back of the appliance or from the owner's manual. If an appliance is rated in amps, multiply amps by operating voltage (120 or 240) to find watts.
3. Convert to DC watt-hours per week. Multiply the total AC watt-hours by 1.15 to correct for inverter loss.
4. Inverter DC input voltage; usually 12, 24 or 48 volts. This is DC system voltage. Usually, the bigger the system the higher the system voltage.
5. Divide the product of the watt-hours by the system voltage. This is total DC amp-hours per day used by the AC loads.
Calculate Your DC Loads
1. List all DC loads in the space provided. If you have no DC loads, skip this section.
2. DC system voltage. Usually 12, 24, or 48 volts. Usually, the bigger the system the higher the system voltage.
3. Find total watt-hours per week used by DC loads. Divide the total watt-hours by the system voltage.
4. Add the AC and DC loads; this is your total amp-hours per day for your system.

THE RELEVANCE OF METAPHYSICS TO CONTEMPORARY SOCIETY

Abstract
The objective of this paper is to examine the relevance of metaphysics to  contemporary society.  It opines that contrary to some people’s opinions that “metaphysics does not bake bread nor build bridges”, metaphysics serves as the foundation upon which all other disciplines are built.  It is in fact, the foundation of all other sciences. To say metaphysics has no place in our contemporary  world is an aberration and a calculated attempt to destroy the structure of the universe because the universe itself encompasses both the physical and the spiritual.  This paper, particularly, examines the relevance of metaphysics to man, the world, science, and technology.  It so important to say that science cannot thrive without metaphysics. Even the scientific enterprise has its being from metaphysics.  The paper argues that there is no justifiable reason for science in discriminating against non-empirical studies like metaphysics owing to their non-empirical characters.  The paper further showed that science should not be the sole criterion or parameter for determining the significance or relevance of other disciplines in human affairs. The method of critical conceptual analysis is employed while existing literature on the subject provide the background to the paper. The paper concludes that metaphysics is so important to human development because no man can exist without going beyond his physical level in order to reflect on both the seen and the unseen realities and it is by moving beyond the physical that man discovers
new things for himself such as new ideas, innovations, discoveries, inventions etc.
                                             











Introduction
        This paper examines the relevance of metaphysics to our contemporary society. It particularly talks about the importance of metaphysics like its rival discipline, science. Part of the objectives of this paper is to argue that some scientific claims, assumptions, and activities have metaphysical presuppositions. Though the major focus is to showcase the relevance of metaphysics to man and his society but not notwithstanding, the science which is believed by many people in the world to have the power of development, cannot do without metaphysics because it derived its origin from it. Science goes beyond itself before it can bring about breakthroughs and inventions. Scientists go beyond this empirical world to reflect and critically reason our solutions to problems which will eventually bring about new discoveries.
        Certainly, metaphysics has been an important part of the history of philosophy and has engaged the minds of philosophers since the time of the Greeks. The Greeks developed over time a massive and complex mythology that explained in animistic, anthropomorphic terms many of the natural phenomena seen in the world around them. The issue is whether it is possible to construct metaphysics as an accomplishing discipline of thought, meaning metaphysics that would be more than a mental and philosophical exercise and that would instead serve to offer a real framework for living
and for understanding the world in which we live. Metaphysics is a branch of philosophy that examines the nature of reality and the relationships between such elements as mind and matter, substance, and attribute.  It includes both ontology and cosmology. Metaphysics is the most abstract division of philosophy and addresses issues of ultimate reality. Metaphysics is concerned with what really exists and what it is that makes reality possible.  The exact nature of metaphysics has long been argued, which brings into question its validity and usefulness.1
The Meaning and Nature of Metaphysics        
          This session examines the nature of metaphysics with the objective of showing that the various attacks on metaphysics have arisen owing to the gross misunderstanding of its nature. This session also shows that metaphysics does not only deal with matters that are beyond physical reality but is also concerned with the whole of reality (both empirical and non-empirical). Indeed, the discriminatory tendency against metaphysics rests majorly on the inability to identify the main nature and scope of metaphysics. However, the world of science cannot even be restricted to objects actually existing but also some of its possible functions and arrangements are implicitly metaphysical.
What is Metaphysics?
        Metaphysics is one of the core areas of philosophy. The word metaphysics’ is derived from two Greek words, ‘meta’ which means “after” and “physical” which means “physics” (or nature). Thus the word
metaphysics literally means “after physics”, “metaphysics”; and it was first used by Andronicus of Rhodes, the editor of Aristotle’s works, around 70B.C. Aristotle had some treatises on physics which bore that title physics. He also had some other treatises dealing with non-physical matters, but without a title. In his arrangement of Aristotle’s works, while editing them for publication, Andronicus placed the treatises dealing with non-physical matters after those dealing with physics.  He did not know what to call them, so he simply called them after physics- “metaphysical,” that is the treatises that come next after those dealing with physics. This was the origin of this word.2
        As a branch of philosophy, it is the study of the totality of being, that is, the nature and structure of reality as a whole.  What metaphysicians have been trying to do down through the ages is to give a comprehensive account of the whole of reality, its nature, its structures, and the place of man in the universe as well as in the totality of reality.  Hence, Alfred North Whitehead, one of the outstanding metaphysicians of this century, defines metaphysics as the Endeavour to frame a coherent, logical, necessary system of general ideas in terms of which every element of our experience can be interpreted.3
        While Aristotle called metaphysics “First philosophy”, Plato called it “Dialectics” and it is the core of Plato’s philosophy. For Plato, metaphysics is the study of reality as distinct from appearance. The reality, for him, lies beyond the material world which is only an imperfect reflection or shadow, and it is
metaphysics (dialectics which takes us beyond this reflection or shadow brings us to reality itself).  Where is reality itself? It is in the world of forms (otherwise known as the world of ideas) which is accessible only to philosophers who make use of dialectics (metaphysics) to get there.4
        For Aristotle (384-322 B.C.), a pupil of Plato and the teacher of Alexander the Great, and one of the most influential philosophers of all times, metaphysics is the science which studies Being qua Being, and the properties inherent in it in virtue of its own nature.  It arises from wonder and is a search for the first principles and ultimate causes of everything which is and that which is substance.  The Aristotelian view of metaphysics continues to exert an influence till today.5
        According to M.J. Kerlin in his paper titled “Nature of Metaphysics”, metaphysics has been an important part of philosophy as well as human history. For him, to reveal the true nature of reality, its contents and structure is to place man within the cosmos in his relation to other kinds of things and to his creator, to determine man’s duty to himself and to God, and the true route to happiness- these are also exhibited in the works of Plato, Descartes, Leibniz, Spinoza, Bradley and so on. No wonder, its advocates have exalted the metaphysical pursuit! Of course, to exalt the metaphysical pursuit is not the same as to exalt metaphysics as a discipline the search for answers to these questions may in itself be notified while one might downgrade metaphysics itself because it never provides final answers.  In truth, in the modern world, we most often compare the supposed
uncertainties of metaphysics with the supposed certainties of science, the first being about the cause of the natural world itself, which can be explained in terms of operation without recourse to a first cause. Through, the question of why things are as they are will persist, and we need a methodology for addressing such questions. Metaphysics provides this even if the method cannot reach a final stage.6
        Henri Bergson in his book “Introduction to metaphysics” explains that in the Eighteenth century, a follower of Leibniz Christian Wolff (1679-1754), a rationalist and an extremely influential pedagogue, divides the subject matter of speculative philosophy into general metaphysics (or ontology)-a transcendental science of all Being, real or possible and special metaphysics, composed of theodicy (or natural theology), which deals with man’s natural knowledge of God, cosmology (or the philosophy of nature), which deals with animate beings especially man in so far as he is rational.  The division of metaphysics, though once widely accepted and still referred to, is no longer generally followed.  In the contemporary period, even the distinction between metaphysics and ontology is not usually sharply drawn in Anglo-American philosophy, although it continues to be employed on the continent. Their ontology refers to an analysis of structure, whereas metaphysics deals with existential propositions, that is, with propositions concerning the existence of what is.7
        Michael Esfeld, a specialist in the metaphysics of science asserts that metaphysics depends on upon science when it is illustrated by considering the
examples of global supervenience, the tenseless versus the tensed theory of time and existence, events versus substances, and relations versus intrinsic properties.  An argument is sketched out for a metaphysics of a four-dimensioned block universe whose contents are events and their sequences, events consisting of physical properties instantiated at space-time points, these properties being relations rather than intrinsic properties. Esfeld also explains that metaphysics…is about what there is and what it is like. But of course, it is concerned not with any old shopping list of what there is and what it is like.  Metaphysicians seek a comprehensive account of some subject matter-the mind, the semantic, or, most ambitiously, everything –in terms of a limited number of more or less basic notions. In doing this, they are following a good example of physicists. The methodology is not that of letting a thousand flowers bloom but that of making do with as a meager a diet as possible.8
        To this end, since metaphysics, in its widest sense, is concerned with the nature and structure of all reality, its concerns are basic and general, thus historically it has been used by systematic philosophers as a basis for such other philosophical disciplines such as ethics, aesthetics, the philosophy of history and philosophical anthropology.  Although metaphysics is taken by some to be the heart of philosophy, it has not been without its critics. There have been many attacks on metaphysics most recently by the logical positivists for its being “other-worldly” imaginative unfounded speculation, or utterly meaningless.9      
             
Man and Metaphysics
        In exemplifying metaphysics as the basic of life contrary to the views of the scientists and other scholars in other fields, Baidyanath construes that in our today world no longer can one describe earth and life in terms of mere laws of physics and chemistry that life just happened by chance on earth.  He argues that there is more to nature than the physics. That is, the understanding of nature itself is beyond human cognition.  No human being on earth, be it scientists or any other can offer a rational justification for all the happenings in the world.10
        Furthermore, metaphysics has been with a man right from inception. Man did not know that he was doing metaphysics. It should be noted that neither Parmenides, Plato, Aristotle, nor any of the founding fathers of Western Philosophy used the word “metaphysics” even though they were metaphysicians. This word as earlier said, came into use by accident as the title of a collection of treatises of Aristotle, indicating the position of these treatises in the arrangement of Aristotle’s works. The concept was, however, central to their philosophies. They were doing metaphysics but without using the word metaphysics”. They attempted to give a comprehensive account of the nature and structure of reality as a whole. For, instance while Aristotle called metaphysics “First philosophy”, Plato called it “Dialectics” and it is the core of Plato’s philosophy.  For him (Plato), metaphysics is the study of reality as distinct from appearance.  The reality, for him, lies beyond the natural world which is only an imperfect reflection or shadow, and it is metaphysics (dialectics) which takes us beyond this reflection or shadow and brings us to
reality itself.  Where is reality itself? It is in the world of forms which is accessible only to philosophers who make use of dialectics (metaphysics) to get there.11 
        In its origin says Copleston, “metaphysics arises simply out of natural desire to understand the world”.12 Metaphysics springs naturally from our innate instinct of curiosity.  The man has a natural curiosity to know, he wants to understand and be able to explain what he sees and experience in the world around him. This natural curiosity to understand and explain what he sees leads him beyond what he sees and leads him into metaphysics. For things point beyond themselves and you cannot understand or explain them without going beyond them. Thus, starting from the world of our empirical experience, we are gradually led beyond it in our attempt to understand it 13 , and we are led into metaphysics. Our horizon becomes broadened beyond the facts of immediate experience, the world of empirical experience. It awakens in us the realization that there is more to things than we can perceive in them with our senses.  We become aware that there is more to reality than is empirically perceptible.  This was how Kant was gradually led from things as they appear to us to things as they are in themselves, from the phenomenal world to the noumenal world. Before Kant, Plato had been led in a similar way gradually from the world empirical experience into the world of forms. It was his attempt to explain motion in the world that Aristotle was led to discover the unmoved mover and the Uncaused cause. It was the attempt to explain the things in the world of empirical experience that led John Locke to discover substance, that led Leibniz to discover monads, that led Hegel to discover absolute spirit, and Schopenhauer to discover the Will to live etc.14
To this end, metaphysics has been with man from inception and man has been making use of it to discover new things in this world of experience and the world that is beyond our world.


The Relationship Between Metaphysics and Science
            This session aims at arguing for the symbiotic relationship that exists between metaphysics and science contrary to the view that the former has no relevance to life and that is of no value and importance to humanity. Having examined and defined metaphysics, what then is science? The Latin word of science is ‘Scire’ (scientia) which means knowledge. This makes science conterminous with knowledge. But a proper historical ordering will place knowledge as prior to science.15 Notable philosophers from antiquity including Aristotle and the Medieval philosophers to the modern period (period of renaissance) made valuable contributions to the growth of science on all fronts. We cannot forget key players like Francis Bacon, Rene Descartes, Kepler, Tycho Brahe, Copernicus, Newton Isaac. John Locke, Albert Einstein, George Berkeley, Gottfried Leibniz, who provided added impetus to the philosophical examination of science in the modern period.16
        The development of science still needs the launching pad provided by Ernest Mach and Charles Sanders Pierce, and in fact, the role of phenomenalism, and logical positivism to the growth of science. Ernest mach was concerned with phenomenalism, for him, science was built out of phenomena, that is, reality as presented to us through the senses. This
made appearance synonymous with reality. The Scientific fact became known as conterminous with appearance since we are dealing with the observable.  For Pierce, science should be seen from the point of view of the ability to derive facts from objective observations, and what is observable should be testable. Science was then seen from the point of view of instrumentalism. The danger here is that science became reduced to an instrumentation enterprise, which determines its own standard and as such above the critique offered by philosophy.17
        To Mickley, science and metaphysics have had a changing relationship with time. The philosophy of the ancient Greece made little distinction between topics that we would now assign the label of science and those that we would assign the label of metaphysics.  The term metaphysics actually is due to Aristotle and refers to the book he wrote after the book on physics, entitled metaphysics or after physics’. It dealt with topics other than physical science topics. Before Aristotle, there was a debate about the nature of physical things and change. Some philosophers maintained that everything is in a state of flux. On the other hand, some argued against this in saying that everything is what it is and cannot change into what it is not. Mickley explains further that, in the 5th century B.C. Democritus proposed a way out of this dilemma.  He maintains that all matter is made up of small indestructible units, which he called atoms. The atoms themselves remained unchanged, having fixed properties. However, they could move and combine in various ways so that macroscopic bodies that they made up might seem to change. This explanation provided for both permanence and flux. This gives rise to the doctrine of materialism.18  The above further establishes the relationship between philosophy and science right from the world go.
        Moreso, several scientific activities and works are underlined by metaphysical presuppositions. Science begins from the conception stage (i.e belief stage which is metaphysical in nature) before breakthroughs come. For example, interpreting natural phenomena is a complex process because contributions come from observation, logic and a variety of methodological, ontological and religious beliefs. Also, complementing this, is the fact that the reversibility of materialism requires that one believes the non-material realm.
        Furthermore, to see how science interrelates with metaphysics is to examine the metaphysical nature of matter. The matter which has been thought to be inert but now we know that it is endowed with motion. As Engels tells us, there is conflict, contradictions, dialectic going on inside matter.19 Also, the Jesuit scientist and paleontologist, Teilhard Chardin tells us that matter is endowed with consciousness (though a very low level of consciousness).20
        All these further corroborate our position that science is swimming in the ocean of metaphysics. Is modern science not becoming more and more metaphysical? There is another area of interest which borders on the question that, do scientists have any reason to believe that current scientific theories are true when all the scientific theories of the past have turned out to be false? How can scientists take a scientific theory that is about entities
and processes no one can observe? This question raised by some scholars represents the kind of question that philosophers usually ask about science. The response to this question and curiosity-that go with it constitutes philosophy of science.21
        To this end, the aforementioned facts have shown or established the nexus between science and metaphysics, and have equally shown that scientific activities are underlined by metaphysical presuppositions.       

The Relevance of Metaphysics to Society.
        The relevance of metaphysics to the development of the society cannot be quantified. Before the relevance of metaphysics is construed on, a little explanation is given below.
        As we have earlier pointed out, modern science is marked out from other disciplines by the procedural method of observation, experimentation, and generalization. By virtue of this method, science has come to be regarded as the surest and most reliable means at man’s disposal for exploring and discovering the secrets of nature, the hard –facts of nature and the laws which govern natural events.  But the question is, are we living in the Age of science alone? If we are to answer this question with another question, why do so many pseudoscientific and non-scientific traditions abound in our society? Religion, myths, superstitions, mysticisms, witchcraft cults, New Age benefits, and nonsense of all sorts have penetrated every nook and cranny of both popular and high culture. One may rationalize that
compared to the magical thinking of the middle Ages things are not so bad. But statistically speaking, pseudoscientific beliefs are experiencing a revival in the late 20th century. A 1990 Gallup poll of 1,236 adult Americans shows percentages of belief in the paranormal that are alarming:

Astrology: 52%
·         Extrasensory perception (ESP) (i.e ability to know things without using the senses of sight, hearing etc): 46%
·         Witches: 19%
·         Aliens have landed on Earth: 22%
·         The lost continent of Atlantis:33%
·         Dinosaurs and Humans lived simultaneously: 41%
·         Noah’s flood: 65%
·         Communication with the dead: 42%
·         Ghost: 35%
·         Actuality had a psychic Experience: 67%.
Other popular beliefs of our time that little or no veracity in evidence include: Dowsing, the Bermuda triangle, Poltergeists, biorhythms, creationism,
 psychokinetic, astrology, ghosts, psychic detectives, unidentified flying objects (UFOs) (e.g a strange object that some people claim to have seen in the sky and believe is a spacecraft from another planet), remote viewing, Kirlian auras, emotions in plants, life and death, monster, graphology, crypto-zoology, clairvoyance, medium, pyramid power, faith healing, bigfoot, psychic prospecting, halted houses, perpetual motion machines,
 anti-gravity locations, and amusingly, astrological birth control. Other polls show that these phenomena are not the quirky beliefs of a handful on the lunatic fringe.23
        From the above, this research has further established the relevance and efficacy of metaphysics in unraveling the secrets of nature that science is incapable of uncovering. This has further shown the importance and relevance of metaphysics to the society, without which the society could not have been acquainted with the aforementioned spiritual entities existing in the society.
        Also, where the scientific thinking/work is dwindling is within the social realm. Individuals, groups, and nations have been trying to solve such social problems as war, crime and poverty for millennia, and yet these social ills still abound. For example, ‘Boko Haram’ insurgency has eaten deep into the fabric of Nigerian History, and nothing has been done to stop it by the so-called scientists. The recommendation of this paper is that metaphysicians should be consulted in terms of nipping in the bud the menace. Metaphysicians such as pastors, Herbalists, prophets, clairvoyants, philosophers etc who see beyond this physical world and who use dialectic to get to the intelligible world should be consulted for solutions to this cankerworm.
        To further buttress the above relevance of metaphysics, the following are to be considered:
(a).  Metaphysics and Practical Life
It is generally believed that metaphysics is pure abstract speculation about theories that have no bearing on practical life. Consequently, metaphysics is generally considered as irrelevant to practical life. Metaphysics, according to this view, is a kind of intellectual hobby or an intellectual game which the philosophers play with abstract theories. If this view were correct then metaphysics could have no role in nation-building and could make no contribution to national or social development. The history of Western philosophy, however, shows that this view is false, for metaphysics (philosophy) has been one of the forces that have shaped the structures of western society. Metaphysics (one of the core branches of philosophy) has had much to do with influencing men’s attitude to life and bringing about changes in societies.  The philosophies of Socrates, Hegel, Spinoza, Dewey, Aristotle were certainly not a pure abstraction that had nothing to do with the practical lives of men.  Nor was the philosophy of a metaphysician called Plato irrelevant to practical life. On the contrary, it gave generations of men a definite worldview which influences their lifestyle. This world-view changed their attitudes towards life and led to the renunciation of material possessions, for through the influence of Plato’s philosophy the things of this world came to be seen in a new light. They are seen as unreal and as shadows of the real things in another world.


(b). Philosophy and Human Development.
To talk of national Development is to talk primarily about the development of human persons. Metaphysics (one of the core branches of philosophy) has a vital contribution to make to the development of a human person. Metaphysics deals with both the physical and spiritual aspects of man. The man is a composite of spirit and matter, metaphysics then helps man to synthesize these elements together in him. The man is such a complex being that has always been to himself a mystery and an insoluble problem. Hence, the French Philosopher, Gabriel Marcel describes the man as a problematic being.24 and Jean-paul Sartre describes him as a being who is not what he is and who is what he is not, a being who puts his own very being into question.25 This further shows the importance of metaphysics in human affairs.
To this end, philosophy generally (metaphysics inclusive) helps to shape man’s moral development. A very important aspect of the development of human personality is moral development. Moral development and maturity on the part of the citizen of a country are pre-requisites for the development of that country.  Indeed, moral development is the most important aspect of national development, for there can be no development of a country if its citizens are morally undeveloped and immature. Moral development on the part of the citizens is, therefore, a condition sine-qua-non for the development of any nation.
From the above, one would see that metaphysics is not about nothing but about some things that have bearing on human lives.

Conclusion
        We have seen that far from being irrelevant to practical life, metaphysics (philosophy) is, on the contrary, one of the powerful forces shaping man’s attitude and the structures of societies. Philosophy, of which metaphysics is a branch, has to do with the development of the society. The development of the society, in turn, leads to the development of the nation. Development of any society or country starts from the conception stage which is metaphysical. We must believe, conceive and rationally think about ideas before nurturing such ideas to bring about the development of a society or country. It is a serious error to see national development only in terms of economic development this, we have said, is not the primary aspect of national development, for national development is primarily the intellectual and moral development of people. unless priority is given to this, the outcome of the developmental process would be a disaster.
        To this end, it is the view of this paper that metaphysics, which is the foundation of all sciences, should be given a pride of place in our society, particularly, it should be incorporated into the curricula of primary, secondary and tertiary institutions of learning globally until then, people would know the relevance of the discipline.
