Shake It Off!

One day a farmer's donkey fell down into a well.

The animal cried piteously for hours as the farmer tried to figure out what to do.

Finally he decided the animal was old and the well needed to be covered up anyway, it just wasn't worth it to retrieve the donkey.

He invited all his neighbors to come over and help him. They all grabbed a shovel and began to shovel dirt into the well.

At first, the donkey realized what was happening and cried horribly. Then, to everyone's amazement, he quieted down.

A few shovel loads later, the farmer finally looked down the well and was astonished at what he saw.

With every shovel of dirt that hit his back, the donkey was doing something amazing. He would shake it off and take a step up.

As the farmer's neighbors continued to shovel dirt on top of the animal, he would shake it off and take a step up.

Pretty soon, everyone was amazed as the donkey stepped up over the edge of the well and trotted off!

Life is going to shovel dirt on you, all kinds of dirt. The trick to getting out of the well is to shake it off and take a step up.

Each of our troubles is a stepping stone. We can get out of the deepest wells just by not stopping, never giving up!

Shake it off and take a step up!

— Timeline of Electricity —

1570
William Gilbert (1540-1603) demonstrates attractive and repulsive force from rubbing many substances together (electrostatic charge); calls them "electrics," and suggests the earth itself is a magnet.
1660s
Otto von Guericke (1602-86) constructs first friction machine to generate static charge, using a revolving ball of sulphur.
1729
Stephen Gray (1696-1736) conducts experiments that show electricity moves.
1740s
Benjamin Franklin (1706-90) proposes the notion of positive and negative charge, conserving a balance except when a deficit is brought about by some means. His famous kite experiments, identifying lightning as a form of electrical discharge, take place in 1752.
1745
Georg von Kleist (c.1700-48) and Pieter van Musschenbroek (1692-1761) invent the Leyden jar, the first condenser (capacitor).
1759
Franz Maria Aepinus (1724-1802) presents the first mathematical treatment of electrical forces and constructs first condenser with parallel plates.
1770s
Henry Cavendish (1731-1810) anticipates later work of Coulomb and Ohm, but shuns publication. The concepts of potential difference and a zero reference point, a ground, are his.
1785
Charles Augustin de Coulomb (1736-1806) works out reciprocal law of electrical force (varying inversely as the square of distance between two charges).
1791
Luigi Galvani (1737-98) demonstrates electrical activity in living tissue, as in muscle and nerve.
1800
Alessandro Volta (1745-1827) invents an electric battery, the first source of DC current.
1819
Hans Christian Oersted (1777-1851) finds that current in a wire can deflect a nearby magnetic needle.
1820
Andre Ampere (1775-1836) discovers that two wires carrying currents act as magnets to attract or repel each other; he describes the relation between current direction and magnetic field orientation.
1826
Georg Simon Ohm (1789-1854) mathematically unites current, voltage, and resistance in the famous "law" bearing his name: V=IR.
1829
Joseph Henry (1797-1878) constructs an electromagnet that can lift in excess of a ton. Demonstrates a telegraph in 1831. Independently he works out principles of magnetic induction at about the same time as Faraday, but publishes slightly later.
1831
Michael Faraday (1791-1867) experimentally characterizes magnetic induction. The most thorough of early electrical investigators, he formulates the quantitative laws of electolysis, the principles of electric motors and transformers, investigates diamagnetic materials, and posits a physical reality for the indirectly observed magnetic and electrical lines of force.
1833
Wilhelm Weber (1804-1891) and Karl Friedrich Gauss (177-1851) successfully operate a telegraph between two distant buildings. They devise the first system of consistent units for electrical measurement. Gauss organizes a European network of observers to record strength and direction of the geomagnetic field.
1834
Heinrich Lenz (1804-65) discovers, at about the same time as Henry and Faraday, that an induced current flows in a direction to oppose the change that induced it--Lenz's law.
1845
Gustav Robert Kirchhoff (1824-87) publishes "circuit rules" for calculating electrical quantities in loop and junction configurations--the sum of all potential drops is always zero.
1851
Heinrich Ruhmkorff (1803-77) invents doubly-wound induction coil; some models produce arcs a foot or more in length. This leads to development of AC transformers.
1864
James Clerk Maxwell (1831-79) describes electromagnetic field in four classic equations, which allow also calculation of the speed of light. Their solution predicts waves within the field.
1869
William Crookes (1832-1914) and Johann Wilhelm Hittorf (1824-1914) independently discover "cathode rays," working with currents in glass tubes of improved vacuum quality.
1888
Heinrich Hertz (1857-94) discovers and measures the waves, radio waves, predicted by Faraday and Maxwell.
1888
Nikola Tesla (1867-1943) invents the first practicable AC motor and polyphase power transmission system, which revolutionizes industry and commerce.
1900s
Charles Proteus Steinmetz (1865-1923) contributes mathematical analysis of more complex nature of AC circuits.

Have a Blessed Day

A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said: "I am blind, please help." There were only a few coins in the hat.
A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words.
Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and asked, "Were you the one who changed my sign this morning? What did you write?"

The man said, "I only wrote the truth. I said what you said but in a different way."

What he had written was: "Today is a beautiful day and I cannot see it."

Do you think the first sign and the second sign were saying the same thing?
Of course both signs told people the boy was blind. But the first sign simply said the boy was blind. The second sign told people they were so lucky that they were not blind. Should we be surprised that the second sign was more effective?

Moral of the Story: Be thankful for what you have. Be creative. Be innovative. Think differently and positively.

Invite others towards good with wisdom. Live life with no excuse and love with no regrets. When life gives you a 100 reasons to cry, show life that you have 1000 reasons to smile. Face your past without regret. Handle your present with confidence. Prepare for the future without fear. Keep the faith and drop the fear.

Great men say, "Life has to be an incessant process of repair and reconstruction, of discarding evil and developing goodness…. In the journey of life, if you want to travel without fear, you must have the ticket of a good conscience."
The most beautiful thing is to see a person smiling… And even more beautiful is, knowing that you are the reason behind it!!!

"Great truths lie in simple things"!!


A boy was watching his grandmother write a letter and he asked her if she is writing a story about him. His grandmother stopped writing her letter and said to told her grandson"I am writing about you, actually, but more important than the words is the pencil I’m using. I hope you will be like this pencil when you grow up".



Intrigued, the boy looked at the pencil. It didn’t seem very special and he remarked "But it’s just like any other pencil I’ve ever seen" "That depends on how you look at things" said the Grandmother –"It has five qualities which, if you manage to hang on them, will make you a person who is always at peace with the world".


First quality: You are capable of great things, but you must never forget that there is a hand guiding your steps. We call that hand God, and He always guides us according to His will.


Second quality: Now and then, I have to stop writing and use a sharpener. That makes the pencil suffer a little, but after wards, he’s much sharper. So you, too, must learn to bear certain pains and sorrows, because they will make you a better person.


Third quality: The pencil always allows us to use an eraser to rub out any mistakes. This means that correcting something we did is not necessarily a bad thing; it helps to keep us on the road to justice.


Fourth quality: What really matters in a pencil is not its wooden exterior, but the graphite inside. So always pay attention to what is happening inside you.


Finally, the pencil’s

Fifth quality: it always leaves a mark. in just the same way, you should know that everything you do in life will leave a mark, so try to be conscious of that in your every action.
