THE TRUE MEANING OF WISDOM

The true meaning of wisdom

This story dates back to the time when Kauravas and Pandavas (figures from the Mahabharata) went to a Gurukul (an ancient school system of India) for education.

There was an atmosphere of keen competition among the students. Each one wanted to be the best in all the subjects that were taught in the ashram, and wished for their teacher, Guru Dronacharya to praise them.

They all studied hard and the teacher was happy with his pupils.

One day, in the middle of summer, Guru Dronacharya had to visit another town for some work. He expected to be away for one week. He called all his students and told them that he would not be around for a few days, and asked them to study a few lessons while he was away.

The next week passed by quickly. On returning, he called the students to the classroom. All the students were looking very happy and entered the classroom with happy faces.

After the class, the Guru asked the boys to tell him what and how much they had studied while he had been away.

Each prince came forward and explained how hard he had worked. One had studied three lessons, another four; some had studied five and so on. The guru made them stand one by one, and wrote down what they had accomplished. At last, it was Yudhishthira’s turn. The teacher looked at him expectantly, as he was the most sincere student in the class.

However, Yudhisthira did not speak out loudly and confidently like the rest had done. His voice was low and he seemed to find it difficult to say anything.

“Tell me, Yudhishthira,” the teacher said encouragingly, "What did you do while I was away? I am sure you finished all the lessons and did some extra work too.”

Yudhishthira answered in a low voice, "I studied, understood and learnt only one sentence, sir.”

Dronacharya was stunned. He could hardly believe his ears. "Just one sentence?” he asked.

“Yes Sir. I could master only one sentence in this short time,” Yudhishthira repeated.

What had happened to Yudhishthira? Why had he spent the whole week learning just one sentence? Yudhishthira was older than all the other pupils and he ought to have worked the hardest. Guru Dronacharya had expected him to serve as an example to the others.

But here was the boy shamelessly declaring that one week was not enough to complete the task set by the teacher! Guru Dronacharya was puzzled.

He didn’t like scolding his pupils. He was never unfair or unreasonable. The children also liked him. They always obeyed him. But now they had worried frowns on their foreheads. Everyone expected the teacher to be very angry with Yudhishthira. They knew that he would have to scold Yudhishthira for his laziness. The children were whispering to each other now. “Will he punish Yudhishthira? How will he punish him? What will he ask him to do? Will he excuse him?"

"After all, this is the first time that he hasn’t done his work,” they said. The guru looked sternly at Yudhishthira. “Aren’t you ashamed of yourself?” he roared. “Everyone in this class is younger than you. They have worked hard and completed the work set by me and you..!" He stopped midway and wiped his face. His hair were standing on end. His face was shining with perspiration. He was trembling with fury.

Yudhishthira’s face remained quiet and tranquil. "Sir, I couldn’t help it. I could finish only this much.” The teacher lost his patience at this.

But Yudhishthira remained calm and tranquil. “I am sorry to have disappointed you, Sir”, he said, "I could study only this much.” Now all the little princes in the class were very worried.

They thought, "First he doesn’t do his work and then he argues with the teacher. He will surely get into a lot of trouble." They expressed their concern to each other through their silent face expressions.

The teacher could not control himself any longer. He said angrily, "I am going to punish you for your disobedience. You are not only lazy, you are being rude and unrepentant too!” Again Yudhishthira said in a low voice, remaining calm and cool, "I am sorry to have disappointed you, Sir. I could only study this much.”

The whole class was surprised. They all liked Yudhishthira. They liked their teacher too. Why didn’t Yudhishthira apologize? The teacher would have forgiven him. He could do the work now and they would help him too. Everyone would be happy once again.

Yudhishthira was being scolded badly. But, the more the teacher scolded him, the more he remained calm and tried to put across his point calmly. It suddenly occurred to the teacher that something was not right. Perhaps, Yudhishthira had done something very unusual! How was he so calm even when he was being scolded? “What is this sentence that you have learnt?” he asked.

Yudhishthira brought out his book and showed the sentence : "CONTROL YOUR ANGER!"

In one flash, the teacher and all the pupils understood what Yudhishthira had done. He had not just learnt the sentence. He had actually practised what he had learnt. It had taken him seven days to master his anger.

Guru Dronacharya's eyes filled with tears when he realized how wise Yudhishthira was. He embraced the boy and said, “My son, forgive me for having been unjust. Today you have taught me, how lessons should be studied! If everyone was like you, the world would be a heaven on earth."

Lesson Summary "Having one application and one goal at a time, will take us somewhere through an optimum utilisation of our inner resources."

BRANCH OF SCIENCE, PHYSICS

 Physics

Physics is the science of matter and its motion. It is an interesting science that deals with concepts like force, mass, energy, and charge. Its goal is to understand the natural world by finding quantitative physical laws for everything from the atoms to the planets, solar systems, and galaxies that occupy the cosmos. Physics is one of the oldest academic disciplines and due to its study of astronomy it may be the oldest of all. The basic laws in physics are universal. Many of the technological inventions that we now see are the result of discoveries in physics. Physics today is such a vast field that many subfields are almost separate sciences.

The early Greeks established the first quantitative physical laws like the Archimedes principle of levers and the buoyancy of bodies in the water. However, they were just bits and pieces of knowledge of physics because they were not organised experiments and documents. Physics started progressing properly only in the 17th century when scientists like Galileo and later Issac Newton helped pioneer the use of mathematics as a fundamental tool in physics. This led to rapid advances in describing the motion of heavenly bodies, the laws of gravity, and the three laws of motion. Later, the laws of electricity, magnetism, and electromechanical waves were developed in the 1800s by Faraday and Maxwell. And soon many others contributed to our understanding of optics and thermodynamics.

Modern physics is said to have started around the turn of the 20th century, with the discovery of X-rays by Roentgen, radioactivity by Becquerel, quantum hypothesis by Planck, relativity theory by Einstein, and atomic theory by Bohr. Quantum mechanics by Heisenberg and Schrödinger in the early 1900s also gave scientists a better understanding of chemistry and solid-state physics, which led to new materials and better electronic and optical components. Nuclear and elementary particle physics have now become important fields, and particle physics is now the basis for astrophysics and cosmology. Advances in electromagnetism have led to the widespread use of electrically driven devices like televisions, computers, home appliances, etc. Advances in thermodynamics have led to the development of motorized transport. Advances in mechanics led to the development of calculus, quantum chemistry, and the use of instruments like the electron microscope in microbiology.

Physics and Mathematics - Physics is closely related to mathematics as it provides the logical structure in which physical laws may be formulated and quantified. Many physics definitions, models, and theories are expressed using mathematical symbols and formulas.

The main difference between physics and mathematics is that physics is primarily concerned with descriptions of the material world, whereas mathematics is focused on abstract logical patterns that may extend beyond the real world. Since physics concentrates on the material world, it always tests its theories through the process known as observation or experimentation. However, without mathematics the physics of the modern world is impossible.

Now let us look at the wide array of subdivisions or branches of physics where one can make a lifelong career in each of them.

30 JANUARY

 Martyrs' Day


Martyrs' Day, also known as Shaheed Diwas, is observed on January 30th every year in India to pay homage to the freedom fighters who sacrificed their lives for the nation's independence.

The day is also the death anniversary of the nation's 'Bapu', Mahatma Gandhi.

It was on this day in 1948 that Mahatma Gandhi was assassinated in the compound of Birla House in New Delhi by Nathuram Godse.

Gandhi, who was born on October 2, 

1869, was one of the most influential leaders of India and played a significant role in the independence of the country. He led major movements against British rule through a non-violent approach. 

His philosophy was based on the principles

of non-violence, the fight for truth

(satyagraha), and political and individual

freedom (Swaraj).

EXCLUSION CULTURE


They bring the nine chairs for ten children, and they tell the children that the winner is the one who gets the chair and whoever remains without a chair is out of the game.

Then they reduce the number of chairs each time and a child comes out every time until one child remains and he is declared the winner.

The child learns the culture of “Myself, myself, and in order to succeed, I must remove others.”

And in Japanese kindergartens, they play the game of chairs too.

They also come with nine chairs for ten kids with a difference!

There they tell the children that you have no more chairs. If one of you remains without a chair, everyone loses.

All the children try to hug each other so that all ten children can sit on nine chairs.

And then they reduce the number of chairs successively with the rule remaining that they must make sure that no one remains without a chair or else they will all lose.

The child learns culture:

“I cannot succeed without the help of others to succeed!”

From exclusion to inclusion.

Isn’t that simply awesome?

We should all change over to this beautiful version of Musical chairs.

WORLD SURYA NAMASKAR DAY

 




Surya Namaskar day is a day to express gratitude to the sun and is observed on Rathsaptami i.e. seventh day (saptami) in the bright half (shukla paksha) of the Hindu month ‘Magha’.

It is customary to perform Surya Puja (worship of sun) on this day.

Haldi-kunku, which starts on the occasion of Makar Sankranti, ends on this day.

Both religious and scientific reasons are given for celebrating Rathsaptami. It is also called Arogya Saptami.

Sun God is known as the most brilliant, powerful, intelligent and omniscient. He is the creator and controller of the world.

To seek His blessings, after sunrise in the morning, Surya Namaskar is performed in an open space on empty stomach, in controlled breathing, with proper postures and chanting shlokas.

This improves our physical health and sharpens memory. This exercise not only gives you a great workout but also gives you spiritual, mental and physical strength.

This ritual is also called Surya upasana.

The mantras of Surya namaskar are

related to the chakras in the body.

GREAT MATHEMATICIAN AND ASTRONOMER

 Aryabhatta


Aryabhatta was the first major mathematician and astronomer from the classical age of India.

His works include Aryabhatiya and the Arya-Siddhanta.

His most famous work was compiled when he was just 23 years old.

‘Ayrabhatiya’ covers several branches of mathematics such as Algebra, Arithmetic, Plane and Spherical Trigonometry.

His principal focus was mathematics; he went into extraordinary insight about arithmetic and geometric movements like 2, 4, 6, and 8 or 2, 10, 50, and 250.

He formulated a brilliant technique for finding the lengths of chords of circles with half chords as opposed to the full chord strategy utilised by the Greeks.

He came up with an approximation of pi.


He was the first mathematician to give what later came to be known as the tables of sine, cosine and converse sine to four decimal spots, which brought forth trigonometry.

Aryabhatta has named the initial 10 decimal places and derived the methods for extracting square roots, summing arithmetic series and solving indeterminate equations of the type ax – by = c.

Aryabhatta worked on the place value

system and discovered zero for the first

time, making use of letters to indicate

numbers and pointing out qualities.



He stated correctly the number of days in a year to be 365, alongside the seven-day week and about an intercalary month embedded into a year to make the calendar adjust to the seasons.

He discovered the position of nine planets and expressed that these likewise rotated around the sun.


He also provided the circumference and measurement of the Earth and the radius of the Earth and the radius of 9 planets.

Aryabhatta challenged many superstitious theories. Aryabhatta also gave a theory on eclipse; he said it wasn’t because of Rahu, but because of shadows cast by the earth and moon.

Aryabhatta pronounced that the moon has no light of its own. It is visible because it mirrors the light of the sun.

He concluded that the earth is round. He also stated that it rotates on its own axis, which is why we have days and night.

Another discipline Aryabhatta explored was astronomy; he concentrated on a few geometric and trigonometric parts of the celestial sphere that are still used to study stars.

In his old age, Aryabhatta composed another treatise, ‘Aryabhatta-Siddhanta’.  It’s a booklet for every day astronomical calculations as well as a guide to examine auspicious times for performing rituals. To this very day, astronomical data provided in this text is used for preparing Panchangs (Hindu calendars).

India’s first satellite was named after him.


There is also an Indian research centre is

called ‘Aryabhatta Research Institute Of

Observational Sciences’ in Nainital.

DEMOCRACY

What is democracy?

Democracy is a form of government in which it is the people who decide who will rule them. Democracy came into existence in ancient Greece, in the city state of Athens, during 6th century BC.

In fact the very word is of Greek origin
and it means ‘rule by the people’.
  



In a democracy, each individual adult in a

country, city or specific area, can vote

for a candidate who will represent him in

the government. This means that power is

not concentrated in the hands of one

person, or a group of people, but is

shared equally by all the members of the

society. The idea of democracy is based

on the belief that everyone should enjoy

the same rights and freedom, in short,

that all men and women are born equal.
