Basics of Electronics (1) (E1)

noreply@blogger.com (Pravin Kumar) — Mon, 10 May 2010 08:38:00 +0530

The field of electronics comprises the study and use of systems that operate by Controlling the flow of electrons (or other charge carriers) in devices such as thermionic Valves and semiconductors. The design and construction of electronic circuits to solve Practical problems is an integral technique in the field of electronics engineering and is equally important in hardware design for computer engineering. All applications of Electronics involve the transmission of either information or power. Most deal only with Information.

Introduction:

Electricity and electronics are a part of our everyday lives. When we get up in the morning the first thing we do is turn on the light; we have just used electricity. The television that we watch, the stereos and radios that we listen to, our heat, our air conditioning, frequently even our cooking all use electricity in one form or another.

These devices work on electrical principles; you should possess a thorough knowledge of the principles of electricity and electronics. The purpose of this article is to introduce the readers to the principles of basic electronics. This task will discuss what electricity is, voltage, current, resistance, Ohm's law, and the color codes for resistors. In the succeeding task, we will cover the different types of circuits, the means of measuring and computing voltage, and current of batteries, especially those in a series-parallel circuit etc.

Electricity:

Composition of Matter:

Matter is defined as anything that occupies space and has weight; that is, the weight and dimensions of all matter can be measured. Examples of matter include air, water, automobiles, clothing, and even our own bodies. Therefore, we can say that matter may be found in any one of three states: solid, liquid, and gaseous.

All material substances, solids, liquids, and gases, are made up of tiny Particles known as atoms. Atoms combine in small groups of two or more to form molecules. Atoms can be further subdivided into smaller particles, some of which have positive electrical charges and others which have negative electrical charges. The atoms of different material substances are discussed in the following paragraphs.

(1) There are over 100 different basic materials in the universe. These basic materials are called elements. Iron is one element, copper; aluminum, oxygen, hydrogen, and mercury are other elements. An element gets its name from the fact that it cannot be broken down easily into simpler (or more elemental) substances. In other words, these 100 basic elements are the building materials from which the universe is made. Close study of any one of these elements reveals that it is made up of those same basic particles, having a positive or a negative electrical charge.

(2) The basic particles that make up all the elements, and thus the universe, are called protons, electrons, and neutrons. A proton is a basic particle having a single positive charge; a group of protons produce a positive electrical charge. An electron is a basic particle having a single negative charge; therefore, a group of electrons produce a negative electrical charge. A neutron is a basic particle having no charge; a group of neutrons, therefore, would have no charge.

First, let us examine the arrangement of atoms in some elements, starting with the simplest of all, and hydrogen. The atom of hydrogen consists of one proton, around which is circling one electron (figure 1 on the following page). There is an attraction between the two particles, because negative and positive electrical charges always attract each other. Opposing the attraction between the two particles, and thus preventing the electron from moving into the proton, is the centrifugal force on the electron, caused by its circular path around the proton. This is the same sort of balance achieved when a ball tied to a string is whirled in a circle in the air.

The centrifugal force exerted tries to move the ball out of its circular path, and is balanced by the string (which can be defined as the attractive force). If the string should break, the centrifugal force would cause the ball to fly away. This is what happens at times with atoms. The attractive force between the electron and proton is sometimes not great enough to hold the electron in its circular path, and the electron gets away.

A slightly more complex atom is the atom of helium. Notice that there are two protons in the center. Because there is an additional proton in the center, or nucleus, of the atom, an electron must be added so as to keep the atom in electrical balance. Notice also that there are additional particles in the nucleus; these are called neutrons. Neutrons overcome the tendency of the two protons to move apart from each other. Just as unlike electrical charges attract, so do like electrical charges repel. Electrons repel electrons. Protons repel protons, except when neutrons are present. Though neutrons have no electrical charge, they cancel out repelling forces between protons in an atomic nucleus and thus hold the nucleus together.

A still more complex atom is the atom of lithium, a light, soft metal. Note that a third proton has been added to the nucleus and that a third electron is now circling around the nucleus. There are also two additional neutrons in the nucleus; these are needed to hold the three protons together. The atoms of other elements can be analyzed in a similar manner. As the atomic scale increases in complexity, protons and neutrons are added one by one to the nucleus and electrons to the outer circles or shells, as they are termed by scientists. After lithium comes beryllium with four protons and five neutrons, boron with five protons and five neutrons, carbon with six and six, nitrogen with seven and seven, oxygen with eight and eight, and so on. In each of these, there are normally the same numbers of electrons circling the nucleus as there are protons in the nucleus.

Composition of Electricity:

When there are more than two electrons in an atom, they will move about the nucleus in different size shells. The innermost shells of the atom contain electrons that are not easily freed and are referred to as bound electrons. The outermost shell will contain what are referred to as free electrons. These free electrons differ from bound electrons in that they can be moved readily from their orbit.

If a point that has an excess of electrons (negative) is connected to a point that has a shortage of electrons (positive), a flow of electrons (electrical current) will flow through the connector (conductor) until an equal electric charge exists between the two points.

Electron Theory of Electricity:

A charge of electricity is formed when numerous electrons break free of their atoms and gather in one area. When the electrons begin to move in one direction (as along a wire, for example), the effect is a flow of electricity, an electric current. Actually, electric generators and batteries could be called electron pumps, because they remove electrons from one part of an electric circuit. For example, a generator takes electrons away from the positive terminal and concentrates them at the negative terminal. Because the electrons repel each other (like electrical chares repel), the electrons push out through the circuit and flow to the positive terminal (unlike electrical charges attract). Thus, we can see that an electric current is, in fact, a flow of electrons from negative to positive.

This is the reverse of the original idea of current flow. Before scientists understood what electric current was, they assumed that the current flowed from positive to negative. Their studies showed that this was wrong; they learned that current are the electron movement from negative (concentration of electrons) to positive (lack of electrons).

Vivekananda quotes (3) (Q9)

noreply@blogger.com (Pravin Kumar) — Mon, 10 May 2010 07:10:00 +0530

1. “GOD is to be worshipped as the one beloved, dearer than everything in this and next life.”

2. “Do not stand on a high pedestal and take 5 cents in your hand and say, "here, my poor man", but be grateful that the poor man is there, so by making a gift to him you are able to help yourself. It is not the receiver that is blessed, but it is the giver. Be thankful that you are allowed to exercise your power of benevolence and mercy in the world, and thus become pure and perfect.”

3. “If money help a man to do well to others, it is of some value; but if not, it is simply a mass of evil, and the sooner it is got rid of, the better.”

4. “Condemn none: if you can stretch out a helping hand, do so. If you cannot, fold your hands, bless your brothers, and let them go their own way.”

5. “As different streams having different sources all mingle their waters in the sea, so different tendencies various though they appear, crooked or straight, all lead to God.”

6. “It is our own mental attitude which makes the world what it is for us. Our thought make things beautiful, our thoughts make things ugly. The whole world is in our own minds. Learn to see things in the proper light. First, believe in this world, that”

History of Computer Part-2 (C2)

noreply@blogger.com (Pravin Kumar) — Sun, 9 May 2010 17:46:00 +0530

A succession of steadily more powerful and flexible computing devices was constructed in the 1930s and 1940s, gradually adding the key features that are seen in modern computers. The use of digital electronics (largely invented by Claude Shannon in 1937) and more flexible programmability were vitally important steps, but defining one point along this road as "the first digital electronic computer" is difficult Notable achievements include:

§ Konrad Zuse's electromechanical "Z machines". The Z3 (1941) was the first working machine featuring binary arithmetic, including floating point arithmetic and a measure of programmability. In 1998 the Z3 was proved to be Turing complete, therefore being the world's first operational computer.

§ The non-programmable Atanasoff–Berry Computer (1941) which used vacuum tube based computation, binary numbers, and regenerative capacitor memory. The use of regenerative memory allowed it to be much more compact than its peers (being approximately the size of a large desk or workbench), since intermediate results could be stored and then fed back into the same set of computation elements.

§ The secret British Colossus computers (1943), which had limited programmability but demonstrated that a device using thousands of tubes could be reasonably reliable and electronically reprogrammable. It was used for breaking German wartime codes.

§ The Harvard Mark I (1944), a large-scale electromechanical computer with limited programmability.

§ The U.S. Army's Ballistic Research Laboratory ENIAC (1946), which used decimal arithmetic and is sometimes called the first general purpose electronic computer (since Konrad Zuse's Z3 of 1941 used electromagnets instead of electronics). Initially, however, ENIAC had an inflexible architecture which essentially required rewiring to change its programming.

Several developers of ENIAC, recognizing its flaws, came up with a far more flexible and elegant design, which came to be known as the "stored program architecture" or von Neumann architecture. This design was first formally described by John von Neumann in the paper First Draft of a Report on the EDVAC, distributed in 1945. A number of projects to develop computers based on the stored-program architecture commenced around this time, the first of these being completed in Great Britain. The first to be demonstrated working was the Manchester Small-Scale Experimental Machine (SSEM or "Baby"), while the EDSAC, completed a year after SSEM, was the first practical implementation of the stored program design. Shortly thereafter, the machine originally described by von Neumann's paper—EDVAC—was completed but did not see full-time use for an additional two years.

Nearly all modern computers implement some form of the stored-program architecture, making it the single trait by which the word "computer" is now defined. While the technologies used in computers have changed dramatically since the first electronic, general-purpose computers of the 1940s, most still use the von Neumann architecture.

Beginning in the 1950s, Soviet scientists Sergei Sobolev and Nikolay Brusentsov conducted research on ternary computers, devices that operated on a base three numbering system of -1, 0, and 1 rather than the conventional binary numbering system upon which most computers are based. They designed the Setun, a functional ternary computer, at Moscow State University. The device was put into limited production in the Soviet Union, but supplanted by the more common binary architecture.

Computers using vacuum tubes as their electronic elements were in use throughout the 1950s, but by the 1960s had been largely replaced by transistor-based machines, which were smaller, faster, cheaper to produce, required less power, and were more reliable. The first transistorized computer was demonstrated at the University of Manchester in 1953. In the 1970s, integrated circuit technology and the subsequent creation of microprocessors, such as the Intel 4004, further decreased size and cost and further increased speed and reliability of computers. By the late 1970s, many products such as video recorders contained dedicated computers called microcontrollers, and they started to appear as a replacement to mechanical controls in domestic appliances such as washing machines. The 1980s witnessed home computers and the now ubiquitous personal computer. With the evolution of the Internet, personal computers are becoming as common as the television and the telephone in the household.

Modern smart phones are fully programmable computers in their own right, and as of 2009 may well be the most common form of such computers in existence

Vivekananda quotes (1) (Q3)

noreply@blogger.com (Pravin Kumar) — Fri, 7 May 2010 18:51:00 +0530

1. “Take up one idea. Make that one idea your life - think of it, dream of it, and live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success that is way great spiritual giants are produced.”

2. “We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves.

4. “You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.”

5. “The goal of mankind is knowledge ... Now this knowledge is inherent in man. No knowledge comes from outside: it is all inside. What we say a man 'knows', should, in strict psychological language, be what he 'discovers' or 'unveils'; what man 'learns' is really what he discovers by taking the cover off his own soul, which is a mine of infinite knowledge.”

History of Computer Part-1 (C1)

noreply@blogger.com (Pravin Kumar) — Fri, 7 May 2010 11:35:00 +0530

The first use of the word "computer" was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued to be used in that sense until the middle of the 20th century. From the end of the 19th century onwards though, the word began to take on its more familiar meaning, describing a machine that carries out computations.

The history of the modern computer begins with two separate technologies—automated calculation and programmability—but no single device can be identified as the earliest computer, partly because of the inconsistent application of that term. Examples of early mechanical calculating devices include the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150–100 BC). Hero of Alexandria (c. 10–70 AD) built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums that might be considered to be a means of deciding which parts of the mechanism performed which actions and when. This is the essence of programmability.

The "castle clock", an astronomical clock invented by Al-Jazari in 1206, is considered to be the earliest programmable analog computer. It displayed the zodiac, the solar and lunar orbits, and a crescent moon-shaped pointer travelling across a gateway causing automatic doors to open every hour, and five robotic musicians who played music when struck by levers operated by a camshaft attached to a water wheel. The length of day and night could be re-programmed to compensate for the changing lengths of day and night throughout the year.

The Renaissance saw a re-invigoration of European mathematics and engineering. Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers, but none fit the modern definition of a computer, because they could not be programmed.

In 1801, Joseph Marie Jacquard made an improvement to the textile loom by introducing a series of punched paper cards as a template which allowed his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability.

It was the fusion of automatic calculation with programmability that produced the first recognizable computers. In 1837, Charles Babbage was the first to conceptualize and design a fully programmable mechanical computer, his analytical engine. Limited finances and Babbage's inability to resist tinkering with the design meant that the device was never completed.

In the late 1880s, Herman Hollerith invented the recording of data on a machine readable medium. Prior uses of machine readable media, above, had been for control, not data. "After some initial trials with paper tape, he settled on punched cards ..." To process these punched cards he invented the tabulator, and the keypunch machines. These three inventions were the foundation of the modern information processing industry. Large-scale automated data processing of punched cards was performed for the 1890 United States Census by Hollerith's company, which later became the core of IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of practical computers had begun to appear: the punched card, Boolean algebra, the vacuum tube (thermionic valve) and the teleprinter.

During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers.

Alan Turing is widely regarded to be the father of modern computer science. In 1936 Turing provided an influential formalisation of the concept of the algorithm and computation with the Turing machine. Of his role in the modern computer, Time magazine in naming Turing one of the 100 most influential people of the 20th century, states: "The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing machine".

The inventor of the program-controlled computer was Konrad Zuse, who built the first working computer in 1941 and later in 1955 the first computer based on magnetic storage.

George Stibitz is internationally recognized as a father of the modern digital computer. While working at Bell Labs in November 1937, Stibitz invented and built a relay-based calculator he dubbed the "Model K" (for "kitchen table", on which he had assembled it), which was the first to use binary circuits to perform an arithmetic operation. Later models added greater sophistication including complex arithmetic and programmability.

Knowledge Management Part-1 (M2)

noreply@blogger.com (Pravin Kumar) — Fri, 7 May 2010 11:13:00 +0530

What is Knowledge Management?

“Knowledge Management is the systematic management of vital knowledge and its associated processes of creation, organization, diffusion, use and exploitation.”

- David Skyrme

Actually we should take the word ‘exploitation’ as positive sense, that is “the fact of using a situation in order to get an advantage for yourself” not “a situation in which somebody treats somebody else in an unfair way, especially in order to make money from their work”

Most of the management people use their knowledge to exploit that is ‘to treat their subordinate unfairly by making them work and not giving them much in return’ instead of ‘to treat them as an opportunity to gain an advantage for both subordinate as well as the organization.

Generally the Knowledge management is called ‘KM’.

Knowledge management (KM) comprises a range of strategies and practices used in an organization to identify, create, represent, distribute, and enable adoption of insights and experiences. Such insights and experiences comprise knowledge, either embodied in individuals or embedded in organizational processes or practice.

KM includes management and operational practices and philosophies, technologies, strategies, and human behavioral traits just to name some the areas that are involved. Hence, both complexity and the many reasons for working with KM result in different ways in which to view the field.

Why Knowledge Management?

n Not to reinvent the wheel : solution exists/ known somewhere in the organization

n Learn from past mistakes – ours or others

n Knowledge resource depletion, Reduction, migration & brain-drain

n Innovate & lead change in the business

“Wise men learn from their own mistakes;

The wiser learn from other mistakes’ too”

Types of Knowledge

Tacit Knowledge

What a person knows, but has not been documented or formally captured. Tacit knowledge is a type of knowledge that is difficult to transfer to another person by means of writing it down or verbalizing it. With tacit knowledge, people are not often aware of the knowledge they possess or how it can be valuable to others. Effective transfer of tacit knowledge generally requires extensive personal contact and trust. Another example of tacit knowledge is the ability to ride a bicycle.

Tacit knowledge is not easily shared. Tacit knowledge consists often of habits and culture that we do not recognize in us. In the field of knowledge, the concept of tacit knowledge refers to a knowledge which is only known by an individual and that is difficult to communicate to the rest of an organization

The tacit aspects of knowledge are those that cannot be codified, but can only be transmitted via training or gained through personal experience. Tacit knowledge has been described as “know-how” -- as opposed to “know-what” (facts), “know-why” (science), or “know-who” (networking). It involves learning and skill but not in a way that can be written down

Explicit Knowledge

Written, codified, or imbedded knowledge that has been transferred to workgroups or to the organization. The most common forms of explicit knowledge are manuals, documents and procedures. Knowledge also can be audio-visual. Works of art and product can be seen as other forms of explicit knowledge where human skills, motives and knowledge are externalized. This website also best example for Explicit knowledge as it document of lot knowledge in it.

என் கவிதை-4

noreply@blogger.com (Pravin Kumar) — Sun, 18 Apr 2010 12:56:00 +0530

தமிழ் என்ன அருமையான அருமை

“தமிழ்-என் தாய் மொழி

அழியும் மொழியோ என

அச்சப்படச் செய்த மொழி

தமிழை...

காப்பாற்றவொன்றும் நான் தேவையில்லை

கரைசேர்க்கவும் நான் தேவையில்லை

களையெடுக்கவும் நான் தேவையில்லை

அதன்

காற்றோட்டத்தில் கரைந்து போய்

காலபூராவும் காலடியில் கிடந்தால் போதும்

காலன் கூட கண்ணீர்விட்டு

கைகொடுத்து போயிவிடுவான் கண்ணியமாக.

காதுகேலாதவன் கூட கண்ணால்

கண்டு மகிழ்ச்சி கொள்வான்-தமிழ்

பேசும் முகத்தில் ஏற்படுத்தும் முத்துசிதறலை

கண்டு-மேனியில் ஏற்படுத்தும் அதிர்வை உணர்ந்து

நான் கவலை கொண்டேன்-தமிழை

காப்பாற்ற யாருமில்லையோ என்று

அது பதிலுக்கு கவலைபட்டது-தான்

யாரையும் காப்பாற்ற இயலவில்லையே என்று

உடனே தமிழ் அன்னையிடம் செப்பினேன்

“என் தமிழ் அன்னையே

என் அன்னையின் வாயால்

உன்னை அறியலானேன்

உலகமே நீயென உணர்ந்து

மகிழ்வாக வாழ்ந்து வர

மற்ற மொழியும் என்னை தீண்ட

உன்னை மறந்து பிதற்றலானேன்

பாவிமனம் போர பாதை புரிந்துகொண்டு

பாதி வழியில் உன்னை அறிய

தாயே நீ போதும் என

காலடியில் கிடக்க தயாரானேன்!

காலடியில் கிடந்து கொண்டு

கதியற்று போயிருக்க-என்

காவியம் படைத்து பிழைத்துகொள்ளேனென

காட்டிய வழியில் நடை பயின்றேன்

நற்கவிதைகள் பிறந்து தாளை ரொப்ப

புது வழிகள் பிறந்து வாழ்க்கை சொக்க

வாழ்த்த நினைத்து வார்த்தையற்று நிக்க

வணங்கிய கையை வளைத்து வரையதுணிகிறேன்

-உன் காவியத்தை“, என்று.

சிரித்துக் கொண்டே அணைத்துக் கொண்டால்

அன்னைக்கே உரிய அன்பை காட்டி”

சஞ்ஜிவின் வலைக்கு வாழ்த்து

சஞ்ஜிவ் என்ற சாதனையாளனின்

சத்தமற்ற சாதனைகள் !

காணக்கிடைக்க களஞ்சியங்களை

காட்டிக்கொடுக்கும் சோதனைகள்!

கற்பனையிலும் கண்டிடாத

கலைகளின் பெரும் கடைகள்!

மின்னணுவில் மிளிரப்போகும்

மின்மினியின் சில விடைகள்!

பட்டி தொட்டி பாமரனும்

படித்தறிய போதனைகள்

வாழ்த்துக்கும் வருத்தத்திற்கும்

வழிகாட்டும் கொட்டகைகள்!

என....

வலைதளத்தை படைத்த உனக்கு

வாழ்த்துகள் பல கோடி

மேலும்...

நீ நோபல் பரிசு பெற நான்

நோகாமல் வாழ்த்துகிறேன்

என் கவிதை-2

noreply@blogger.com (Pravin Kumar) — Fri, 16 Apr 2010 08:15:00 +0530

இளைஞன் ஒருவன்

இளைஞன் ஒருவன்...

“வெற்றி வேண்டும் வெற்றி வேண்டும்

வெறியுடன் உழைக்கிறேன்

வேகத்தையும் விவேகத்தையும் சேர்த்து

வைத்து உழைக்கிறேன்

வெற்றி பெற்ற பலமனிதரை பார்த்து

பார்த்து உழைக்கிறேன்

வேதனையையும் சோதனையையும் தாண்டி

தாண்டி உழைக்கிறேன்

வெள்ளி தங்கம் காசுகளை

எண்ணாமல் உழைக்கிறேன்

வேற்றுமையை கலையெடுக்க வேண்டி

ஓடி உழைக்கிறேன்

புத்தம்புது பூமிதனை படைத்-

தெடுக்க உழைக்கிறேன்

புதுமைகளை புகுத்திவிட பாடி

ஓடி உழைக்கிறேன்

பட்டென்று தண்ணீர் பட

துடித்தெழுந்து பார்க்கிறேன்

உழைத்ததெல்லாம் கனவினில்தான்-என

உணர்ந்து வேர்க்கிறேன்

சட்டென்று அவ்விடத்தில் நான்

படுத்து தூங்கினேன்

விட்ட கனவு வாராதா-என

நினைத்து ஏங்கினேன் ”

“இளைஞா....

கனவினில் தான் வெற்றியென

ஒருபோதும் நினையாதே

கனவினை தான் கண்டுவிட்டு

உழைப்பதை நீ மறவாதே ”

இளைஞன் கனவினிலே ஒருவன்

ஒளியாய் வந்தான்

மேற்கண்ட வரியை அவனுக்கு

பதிலாய் தந்தான்

பிரிவின் வலி

மனதிற்குள்ளே வலியொன்னு தெரியுது
வார்த்தை கூட வெளிவர மறுக்குது

பிரிவை பற்றி உதடென்ன சொல்வது

கண்கள் மட்டும் கண்ணிரால பேசுது!!!

நட்பென்ற வார்த்தையிலே துவங்கினோம்!

நாளேல்லாம் பேசிதான் பழகினோம்!

துன்பத்திலும் கைதந்து உதவினோம்!

இனிஎப்படிதான் நாமெல்லாம் விலகுவோம்?

கல்லூரி வாழ்க்கை கண்முன் வந்திநிற்க

மனதின் போக்கை ஞாபங்கள் வென்றுநிற்க

பிரியும் நாள் இன்றுதான் என்றிருக்க

ஆட்டம் பாட்டமென நாள்முழுதும் சென்றிருக்க

முகத்தினிலே புன்னகையை பூக்கவிட்டு…

மனதினிலே அழுகையைதான் தொடரவிட்டு…

பிரிவிலும் சோலைவனமாய் தோன்றிடுவோம்!!!

பிரிந்தபின் பாலைவனமாய் போயிடுவோம்?????????

(குறிப்பு: இக்கவிதை எனது கல்லூரி வாழ்வின் முடிவை எனது நண்பர்களுடன் கொண்டாடுவதற்காக ( பிரிவு உபாச்சார நிகழ்ச்சிகாக) எழுதியது. என் கல்லூரி நண்பர்களுக்கே என்னை கவிஞனாக்கிய சிறப்பு சாரும். அதனால் அவர்களுக்கு இதை காணிக்கையாக்குகிறேன். நன்றி)

Love Poem-1

noreply@blogger.com (Pravin Kumar) — Mon, 12 Apr 2010 18:00:00 +0530

Love's Harvest

From the Genesis of our created love,
Springs this season of celebration,
Signs and wonders from above,
Brought forth God's Revelation.

Within this, our day, I sow my vows,
The seeds to my remaining life,
Surrendered, here-in, to Beauteous Bride
Now stood before me as my Wife.

Loves olive tree, so rich with fruit,
Shoots forth from soil of hearts divine,
To end the season of loves pursuit,
For now the Lord has made you mine.

Amongst the wheat there grows no weeds,
For this love I hold is pure and true,
The love that blossoms from these seeds,
Flourishes, Elaine, only for you.

And, so to God I raise my hand,
With glowing heart I lift my voice,
To thank Him for a Love so Grand,
And Bride who makes my heart rejoice.

- Bryn-mor Williams
