காத்தெல்லாம் மகன் பாட்டு, காகிதத்தில் அவன் எழுத்து
ஊரெல்லாம் மகன் பேச்சு, உன் கீர்த்தி எழுதலையே௦.

எழுதவோ படிக்கவோ இயலாத தாய் பற்றி
எழுதி என்ன லாபமன்னு எழுதாம போனேனோ ?

உனக்கு ஒண்ணு ஆனதுனா எனக்கு வேற தாயும் உண்டா ?????

ஹிக்ஸ் போஸான் - God's Particle

கடவுளின் அணுத் துகள் என்று சொல்லப்படும் “ஹிக்ஸ் போஸான்” கண்டுபிடிப்பு: 99.999% உறுதி செய்யப்பட்டுள்ளது !!!
கடவுளின் அணுத்துகள் என்று அழைக்கப்படும் ஹிக்ஸ் போஸான் இருப்பது 99.999% உறுதி செய்யப்பட்டுள்ளதாக இது தொடர்பான ஆராய்ச்சியை நடத்தி வரும் விஞ்ஞானிகள் அறிவித்துள்ளனர்.

இதன்மூலம் ஹிக்ஸ் போஸான் இருக்கிறதா இல்லையா என்பது தொடர்பான கேள்விகளுக்கு ஓரளவுக்கு விடை கிடைத்திருக்கிறது.

Big Bang எனப்படும் பெரு வெடிப்பைத் தொடர்ந்தே அணுக்களும், மூலக்கூறுகளும், கிரகங்களும், இந்த பேரண்டமும்(universe) உருவாயின என்பது கோட்பாடு.

இதன்படி பிக் பேங் வெடிப்பு நிகழ்ந்த கணத்தில் அணுக்கள் ஒலியை விட பயங்கரமான வேகத்தில் எல்லா திசைகளிலும் சிதறின. அப்போது அந்த அணுக்களுக்கு எந்த நிறையும்(mass) இல்லை.

ஆனால், ஹிக்ஸ் போஸான் எனப்படும் சக்தியோடு அவை தொடர்பு கொண்ட பிறகே அந்த அணுக்களுக்கு நிறை கிடைத்தது. இது தான் இந்த பேரண்டம் உருவானதன் அடிப்படை என்று சொல்கிறது ஸ்டாண்டர்ட் மாடல் தியரி...

இந்த கோட்பாட்டின்படி(தியரி) இந்த யுனிவர்ஸ் உருவாக முக்கிய அடிப்படையாக இருந்தவை 12 வகையான அணுத் துகள்கள். அடுத்தடுத்து நடந்த ஆய்வுகளில் 11 அணுத் துகள்கள் அடையாளம் காணப்பட்டு விட்டன. அவை இருப்பதையும் பார்த்து விட்டோம்.

ஆனால் இதுவரை கண்ணுக்குப் புலப்படாத அணுத் துகள் தான் ஹிக்ஸ் போஸான்.

இதையடுத்தே ஹிக்ஸ் போஸானை கண்டுபிடிக்கும் முயற்சிகள் தொடங்கின. அமெரிக்காவில் தான் முதலில் இந்த ஆய்வுகள் நடந்தன. பல ஆண்டுகள் நீடித்த இந்த சோதனைகள் எந்த முடிவையும் எட்டாததால், அந்த ஆய்வுகளுக்கு நிதி தருவதை அமெரிக்க அரசு நிறுத்திவிட்டது.

இதைத் தொடர்ந்தே பிரான்ஸ்- சுவிஸ் எல்லையில் ஜெனீவா அருகே ஐரோப்பிய அணு ஆராய்ச்சிக் கழகம்(CERN) அமைத்த மாபெரும் வட்ட சுரங்க ஆய்வகத்தில் இந்தச் சோதனைகள் தொடங்கின. அணுத் துகள்களுக்கு நிறையைத் தருவதாகக் கருதப்படும் ஹிக்ஸ் போஸான் தான் நம்மைச் சுற்றியுள்ள இந்த பேரண்டத்தின் பெரும் பகுதியை நிறைத்திருக்கிறது.

இதனால் பாதிக்கப்படாத ஒரே அணுத் துகள் ஒளிக் கதிர்களான போட்டான்கள் மட்டுமே. இதனால் தான் போட்டான்களுக்கு நிறை இல்லை. மற்ற எல்லா அணுத் துகள்கள் மீதும் இந்த ஹிக்ஸ் போஸான் தனது ஆதிக்கத்தைச் செலுத்தி நிறையைத் தந்துவிடுகிறது என்று சொல்கிறது ஸ்டாண்டர்ட் மாடல் தியரி. 

ஆனால், அதில் விடுபட்டு நிற்கும் ஒரே கேள்வி அணுத் துகள்களுக்கு நிறையைத் தரும் ஹிக்ஸ் போஸானின் எடை என்ன என்பதே. (நிறை என்றால் என்ன?. ஒரு பொருளின் எடை மைனஸ் புவிஈர்ப்பு விசை தான் நிறை. அதாவது நமது எடை 55 கிலோ என்றால் நம் உடலின் மீது புவிஈர்ப்பு விசை செலுத்தும் இழுவிசையைச் சேர்த்தது தான் 55 கிலோ எடை. இதில் புவிஈர்ப்பு விசையை கழித்துவிட்டால் மிச்சமிருக்கும் எடையே நிறை)

பார்க்கவே முடியாத ஹிக்ஸ் போஸானை நிரூபிக்க ஒரே வழி. அதன் எடையைக் கண்டுபிடிப்பதே. இந்த ஆய்வைத் தான் CERN நடத்தியது.

இதற்காகத் தான் சிறிய அளவிலான Big Bang வெடிப்பை செயற்கையாக நடத்திப் பார்த்தனர். இதற்காகத் தான் நியூட்ரான்-புரோட்டான்களின் அதி பயங்கர மோதலை நடத்தினர். இந்த மோதலில் வெடித்துச் சிதறிய பல்வேறு அணுத் துணைத் துகள்கள், கதிர்வீச்சுகளுக்கு இடையே ஹிக்ஸ் போஸானையும்(அதன் எடையை) தேடினர்.

ஸ்டாண்டர்ட் மாடல் தியரியின் படி ஹிக்ஸ் போஸானின் எடை 125 கிகா எலெக்ட்ரோ வோல்ட்ஸ்(GeV) என்ற அளவில் இருக்க வேண்டும். அதாவது அணுக்களுக்குள் இருக்கும் துணைத் துகளான புரோட்டானின் எடையை விட 125 மடங்கு அதிகமாக இருக்க வேண்டும்.

CERN விஞ்ஞானிகள் நடத்திய ஆராய்ச்சியில் 125.3+ GeV எடை கொண்ட துகள் கண்டுபிடிக்கப்பட்டுள்ளது. இது 99.999% ஹிக்ஸ் போஸானாகத் தான் இருக்க வேண்டும் என்கிறார்கள்

Power of Positive Talk

Amazing article from the GREAT ONE Dr.Avul Pakir Jainulabdeen Abdul Kalam

“I remember my dad teaching me the power of language at a very young age. Not only did my dad understand that specific words affect our mental pictures, but he understood words are a powerful programming factor in lifelong success.

One particularly interesting event occurred when I was eight. As a kid, I was always climbing trees, poles, and literally hanging around upside down from the rafters of our lake house. So, it came to no surprise for my dad to find me at the top of a 30-foot tree swinging back and forth.. My little eight-year-old brain didn't realize the tree could break or I could get hurt. I just thought it was fun to be up so high.

My older cousin, Tammy, was also in the same tree. She was hanging on the first big limb, about ten feet below me. Tammy's mother also noticed us at the exact time my dad did. About that time a huge gust of wind came over the tree. I could hear the leaves start to rattle and the tree begin to sway. I remember my dad's voice over the wind yell, "Bart, Hold on tightly." So I did. The next thing I know, I heard Tammy screaming at the top of her lungs, laying flat on the ground. She had fallen out of the tree.

I scampered down the tree to safety. My dad later told me why she fell and I did not. Apparently, when Tammy's mother felt the gust of wind, she yelled out, "Tammy, don't fall!" And Tammy did. fall.

My dad then explained to me that the mind has a very difficult time processing a negative image. In fact, people who rely on internal pictures cannot see a negative at all. In order for Tammy to process the command of not falling, her nine-year-old brain had to first imagine falling, then try to tell the brain not to do what it just imagined. Whereas, my eight-year-old brain instantly had an internal image of me hanging on tightly.

This concept is especially useful when you are attempting to break a habit or set a goal. You can't visualize not doing something. The only way to properly visualize not doing something is to actually find a word for what you want to do and visualize that. For example, when I was thirteen years old, I played for my junior high school football team. I tried so hard to be good, but I just couldn't get it together at that age. I remember hearing the words run through my head as I was running out for a pass, "Don't drop it!" Naturally, I dropped the ball.

My coaches were not skilled enough to teach us proper "self-talk." They just thought some kids could catch and others couldn't. I'll never make it pro, but I'm now a pretty good Sunday afternoon football player, because all my internal dialogue is positive and encourages me to win. I wish my dad had coached me playing football instead of just climbing trees. I might have had a longer football career.

Here is a very easy demonstration to teach your kids and your friends the power of a toxic vocabulary. Ask them to hold a pen or pencil. Hand it to them. Now, follow my instructions carefully. Say to them, "Okay, try to drop the pencil." Observe what they do.

Most people release their hands and watch the pencil hit the floor. You respond, "You weren't paying attention. I said TRY to drop the pencil. Now please do it again." Most people then pick up the pencil and pretend to be in excruciating pain while their hand tries but fails to drop the pencil.

The point is made.

If you tell your brain you will "give it a try," you are actually telling your brain to fail. I have a "no try" rule in my house and with everyone I interact with. Either people will do it or they won't. Either they will be at the party or they won't. I'm brutal when people attempt to lie to me by using the word try. Do they think I don't know they are really telegraphing to the world they have no intention of doing it but they want me to give them brownie points for pretended effort? You will never hear the words "I'll try" come out of my mouth unless I'm teaching this concept in a seminar.

If you "try" and do something, your unconscious mind has permission not to succeed. If I truly can't make a decision I will tell the truth. "Sorry John. I'm not sure if I will be at your party or not. I've got an outstanding commitment. If that falls through, I will be here. Otherwise, I will not. Thanks for the invite."

People respect honesty. So remove the word "try" from your vocabulary.

My dad also told me that psychologists claim it takes seventeen positive statements to offset one negative statement. I have no idea if it is true, but the logic holds true. It might take up to seventeen compliments to offset the emotional damage of one harsh criticism.

These are concepts that are especially useful when raising children.

Ask yourself how many compliments you give yourself daily versus how many criticisms. Heck, I know you are talking to yourself all day long. We all have internal voices that give us direction.

So, are you giving yourself the 17:1 ratio or are you shortchanging yourself with toxic self-talk like, " I'm fat. Nobody will like me. I'll try this diet. I'm not good enough. I'm so stupid. I'm broke, etc. etc.."

If our parents can set a lifetime of programming with one wrong statement, imagine the kind of programming you are doing on a daily basis with your own internal dialogue.

Here is a list of Toxic Vocabulary words.

Notice when you or other people use them.

But: Negates any words that are stated before it.

Try: Presupposes failure.

If: Presupposes that you may not.

Might: It does nothing definite. It leaves options for your listener..

Would Have: Past tense that draws attention to things that didn't actually happen.

Should Have: Past tense that draws attention to things that didn't actually happen (and implies guilt.)

Could Have: Past tense that draws attention to things that didn't actually happen but the person tries to take credit as if it did happen.

Can't/Don't: These words force the listener to focus on exactly the opposite of what you want. This is a classic mistake that parents and coaches make without knowing the damage of this linguistic error.

Examples:

Toxic phrase: "Don't drop the ball!"

Likely result: Drops the ball

Better language: "Catch the ball!"

Toxic phrase: "You shouldn't watch so much television."

Likely result: Watches more television.

Better language: "I read too much television makes people stupid. You might find yourself turning that TV off and picking up one of those books more often!"

Exercise: Take a moment to write down all the phrases you use on a daily basis or any Toxic self-talk that you have noticed yourself using. Write these phrases down so you will begin to catch yourself as they occur and change them.

Open Source Hardware will revolutionize the way we learn Electronics!!

Open Source Hardware (OSHW) movement is what I am talking about. It’s not a new concept, many of you guys may already be involved (or aware of) in this movement. For the newbies who still find a little confused with OSHW terminology, I will give a briefing.

Open Source Hardware is pretty same in concept with Open Source Software movement. In the case of operating systems,

Linux is open source where as Microsoft Windows is not!

If you go for Linux – you will get its source code and you can modify the operating system on your own ideas and you can redistribute the same. In the case of Windows, you won’t get its source code and any attempt to modify/tweak Windows is considered illegal because their source codes are protected by IP (Intellectual Property) laws and patents. Similar is the case in hardware. You are not supposed to tweak/modify an Apple Iphone. Even “jail breaking” an Iphone is considered illegal. No way will you ever get the design schematics of its hardware! In the case of Open Source Hardware, you will get access to complete documentation (layouts, schematics, software codes) of the device you purchase and you can modify the device on your own (to any extent) and you can freely redistribute the device (in your own brand name). I hope you now got an idea about OSHW movement.

It’s quite interesting – right ?

Now comes the questions –

where can I find an open source device ?

How can I work upon it?

How can I buy one?

The best example I can suggest now is about Arduino.

Arduino is a single board micro controller (using Atmel AVR) – which can sense it’s surrounding environment using many sensors (to get input) and control many output devices (based on input) such as lights, motors and actuators. It’s an open source project and all the documentation is available in their website (http://www.arduino.cc/). You can either buy the hardware or you can make your own by assembling the circuitry as given in the website.

To know more about arduino, I suggest you read an article written by the author Anish -Arduino for Beginners

Now Arduino – is just one kind of the many out there.

Let’s work together to build a great community!

Brain Boosting Activities

If you don’t keep your mind active,

Your brain loses some of its functionality as you age,

Which causes memory loss, brain fog, and even Alzheimer’s?

A well-stimulated brain also elevates your mood, which helps you feel better on the inside.

Here are 15 brain boosting activities:

1. Play games that challenge and stimulate your mind.

These include:

* Picture Puzzles

* Strategy Games

* Crossword Puzzles

* Card Games

* Deduction Games (such as Clue)

* Visualization Puzzles

* Optical Illusions

2. Reading stimulates the brain as it activates your imagination. Reading also helps with memory retention and problem solving, especially if you’re reading a mystery. Also, self-help books stimulate your brain by helping you to think for yourself, as well as find solutions in your mind.

3. Exercising helps circulate blood that carries oxygen to your brain. Over the long-term, exercise is proven to increase brainpower and even create new neurons.

4. Stimulate your brain with meditation. Meditation has been shown to increase your IQ, relieve stress, and promote a higher level of brain functioning. Meditation also stimulates the prefrontal cortex of the brain, the area of the brain responsible for advanced thinking, ability and performance.

5. Deep breathing helps deliver oxygen to your brain. Oxygen helps you be more alert and awake. As little as 10 to 15 minutes of deep breathing daily can increase brain functionality.

6. Taking fish oil supplements is literally like membrane material for the brain.. The two primary components in fish oil, DHA and EPA, strengthen the emotional center of the brain and boost focus.

7. Studies have proven that listening to music strengthens the right hemisphere of the brain and actually changes the structure of it. Also, people who listen to music are shown to be more emotionally intelligent than those who don’t.

8. Writing improves memory and thought expression. Writing articles, blogs, or journal entries stimulates thought processes, which also enhances brain function.

9. Sleep clears out brain clutter and reduces brain fog. When you don’t get enough sleep at night, your memory and normal brain function suffers.

10. Painting is shown to be an effective brain booster in that it sparks the creativity within you. Even if you’ve never tried painting before, give it a shot. You’ll find that you feel more creative and may actually enjoy it.

11. Starting the day out with a good breakfast has been proven to supply energy to the brain and body for the whole day. When you skip breakfast, you’re missing out on a powerful edge, both physically and mentally.

12. Walking allows you to clear your mind and thoughts. Not only is it good exercise for your body, walking gives your brain a chance to wander freely, clearing it of any troublesome thoughts.

13. Drink a serving of pure fruit juice. Fruit juice contains nutrients that revitalize and refresh the brain. Juices to drink are pomegranate, blueberry, and cranberry as they deliver more focus and energy.

14. Students who drink some caffeine before an exam typically have higher scores than those who don’t. This is because caffeine stimulates activity in the brain, which produces better focus and thinking ability. Don’t overdo it though!

15. Draw a picture. Like painting, drawing stimulates the creative side of your brain. So get out some colored pencils and start boosting your brainpower.

To get the most out of these brain boosting activities, mix them up and do a variety of them at different times. Just choosing one won’t boost your brainpower, however, combining and alternating them will give your brain the added boost you need now and in the long run.

National Science Day!

National Science Day is celebrated in India on February 28 each year to mark the discovery of the Raman effect by Indian physicist Sir Chandrasekhara Venkata Raman on 28 February 1928.

Full Name: Sir Chandrasekhara Venkata Raman
Born On: November 7, 1888
Born In: Thiruvanaikoil, Tiruchirappalli, Madras Presidency, British India
Died: November 21, 1970
Death Place: Bangalore, Karnataka, India
Nationality: Indian
Fields: Physics
Achievements: He was the first Indian scholar who studied wholly in India received the Nobel Prize.

Mini Biography:

C.V. Raman is one of the most renowned scientists produced by India. His full name was Chandrasekhara Venkata Raman. For his pioneering work on scattering of light, C.V. Raman won the Nobel Prize for Physics in 1930.

Chandrashekhara Venkata Raman was born on November 7, 1888 in Tiruchinapalli, Tamil Nadu. He was the second child of Chandrasekhar Iyer and Parvathi Amma. His father was a lecturer in mathematics and physics, so he had an academic atmosphere at home. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics. In 1907, C.V. Raman passed his M.A. obtaining the highest distinctions.

During those times there were not many opportunities for scientists in India. Therefore, Raman joined the Indian Finance Department in 1907. After his office hours, he carried out his experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta. He carried out research in acoustics and optics.

In 1917, Raman was offered the position of Sir Taraknath Palit Professorship of Physics at Calcutta University. He stayed there for the next fifteen years. During his tenure there, he received world wide recognition for his work in optics and scattering of light. He was elected to the Royal Society of London in 1924 and the British made him a knight of the British Empire in 1929. In 1930, Sir C.V. Raman was awarded with Nobel Prize in Physics for his work on scattering of light. The discovery was later christened as “Raman Effect”.

In 1934, C.V. Raman became the director of the newly established Indian Institute of Sciences in Bangalore, where two years later he continued as a professor of physics. Other investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1947, he was appointed as the first National Professor by the new government of Independent India. He retired from the Indian Institute in 1948 and a year later he established the Raman Research Institute in Bangalore, where he worked till his death.

Sir C.V. Raman died on November 21, 1970.

Heat Hack – A New Method to Steal ATM Pin Codes!!

A team of UC San Diego security researchers presented a paper on how your Automatic Teller Machine (ATM) pin code can be stolen using the heat that our fingers leave behind. With the help of a digital infrared camera, the person immediately following you can know the keys you pushed, with 80% accuracy.

Frightened? Don’t worry! There are some drawbacks to this method of stealing ATM pins.

Even if the criminal can determine the digits pressed, it is very difficult for him to know the order in which they were pressed. That means he will have to use different combinations of the 4 digits. The second drawback to this ATM pin theft using the heat left behind is that it works only on plastic keypads. This is because if the keypad is made of metal, it gives off too much heat noise that the IR camera cannot distinguish accurately which keys are pressed.

And most of all, a good IR camera that fits this purpose will cost something around $18,000. If one has so much money to get hold of such a costly camera, then I seriously doubt that he will go for stealing ATM pins!

But this does not change the simple truth that our ATM pins are vulnerable to this ‘Heat Hacking’. This type of hacking is not limited to ATM machines, but can be done on keypad safes, security doors, keypad activated garage doors or car doors.

But we can always eliminate the little chance of pin theft by just placing our hand over the entire keypad after entering the ATM pin so that heat is equally given to all the keys in the ATM keypad. This simple step can ruin all the hacking plan of the suspected ‘criminal’ just behind you at the ATM. Do it just as a precaution!

Neutrinos - Move Faster Than the Speed of Light!!

From our childhood days, we have studied that nothing in this planet travels faster than light. It has been defined as the ultimate speed in our universe. This has been backed up by many experiments, tests and measurements in many ways possible.

But all these remain as just theories, as a simple neutrino transfer experiment conducted by physicists at The European Organization for Nuclear Research (CERN) from their headquarters in Geneva to Gran Sasso Laboratory in Italy (732 kilometres away), proved to be faster than light speed.

The neutrinos had some special characteristics and did not interact with normal matter. As a result, they already predicted that the neutrons would travel fast. Their main aim was to test the frequency of oscillations when the transmission of neutrinos from the source changes its characteristics, as soon as it reaches the destination in Italy. This was when the researchers found something odd with the experiment. The neutrinos reached the destination in a few billionths of a second early. This time proved to be faster than the time of travel of light emitted from Geneva to Gran Sasso.

This is not an isolated anomaly, but has been going on for years. The team has now measured some 14,000 batches of neutrinos coming across that distance, and they say they’ve reached a point where the statistical significance is such that, were they trying to prove anything else, it would count as a formal scientific discovery. But, whatever may be the result, they are not able to back up the fact with any scientific evidence.

Nobody, least of all the researchers involved, is ready to call the Standard Model’s upper speed limit busted just yet. But as they do not have any scientific proof to what happened, they are ready t share their new discovery to a wider scientific community. As this new phenomenon has been taken seriously by all researchers around the globe, we will have to wait and see if anyone can produce a satisfactory answer.

To the Awakened India - Poem by Swami Vivekanandar

Swami Vivekananda (12 January 1863 – 4 July 1902), born Narendranath Dutta, was the chief disciple of the 19th century saint Ramakrishna Paramahansa and the founder of theRamakrishna Math and the Ramakrishna Mission.

(Written to Prabuddha Bharata or Awakened India, in August 1898,when the journal was transferred from Madras to Almora Himalayas,into the hands of the Brotherhood founded by Swami Vivekananda.)

Once more awake!
For sleep it was, not death, to bring thee life
Anew, and rest to lotus-eyes for visions
Daring yet. The world in need awaits, O Truth!
No death for thee!

Resume thy march,
With gentle feet that would not break the
Peaceful rest even of the roadside dust
That lies so low. Yet strong and steady,
Blissful, bold, and free. Awakener, ever
Forward! Speak thy stirring words.

Thy home is gone,
Where loving hearts had brought thee up and
Watched with joy thy growth. But Fate is strong —
This is the law — all things come back to the source
They sprung, their strength to renew.

Then start afresh
From the land of thy birth, where vast cloud-belted
Snows do bless and put their strength in thee,
For working wonders new. The heavenly
River tune thy voice to her own immortal song;
Deodar shades give thee eternal peace.

And all above,
Himala's daughter Umâ, gentle, pure,
The Mother that resides in all as Power
And Life, who works all works and
Makes of One the world, whose mercy
Opens the gate to Truth and shows
The One in All, give thee untiring
Strength, which is Infinite Love.

They bless thee all,
The seers great, whom age nor clime
Can claim their own, the fathers of the
Race, who felt the heart of Truth the same,
And bravely taught to man ill-voiced or
Well. Their servant, thou hast got
The secret — 'tis but One.

Then speak, O Love!
Before thy gentle voice serene, behold how
Visions melt and fold on fold of dreams
Departs to void, till Truth and Truth alone
In all its glory shines —

And tell the world —
Awake, arise, and dream no more!
This is the land of dreams, where Karma
Weaves unthreaded garlands with our thoughts
Of flowers sweet or noxious, and none
Has root or stem, being born in naught, which
The softest breath of Truth drives back to
Primal nothingness. Be bold, and face
The Truth! Be one with it! Let visions cease,
Or, if you cannot, dream but truer dreams,
Which are Eternal Love and Service Free.

What is Duty? (Speech by Vivekananda)

It is necessary in the study of Karma-Yoga to know what duty is. If I have to do something I must first know that it is my duty, and then I can do it. The idea of duty again is different in different nations. The Mohammedan says what is written in his book, the Koran, is his duty; the Hindu says what is in the Vedas is his duty; and the Christian says what is in the Bible is his duty. We find that there are varied ideas of duty, differing according to different states in life, different historical periods and different nations. The term "duty", like every other universal abstract term, is impossible clearly to define; we can only get an idea of it by knowing its practical operations and results. When certain things occur before us, we have all a natural or trained impulse to act in a certain manner towards them; when this impulse comes, the mind begins to think about the situation. Sometimes it thinks that it is good to act in a particular manner under the given conditions; at other times it thinks that it is wrong to act in the same manner even in the very same circumstances. The ordinary idea of duty everywhere is that every good man follows the dictates of his conscience. But what is it that makes an act a duty? If a Christian finds a piece of beef before him and does not eat it to save his own life, or will not give it to save the life of another man, he is sure to feel that he has not done his duty. But if a Hindu dares to eat that piece of beef or to give it to another Hindu, he is equally sure to feel that he too has not done his duty; the Hindu's training and education make him feel that way. In the last century there were notorious bands of robbers in India called thugs; they thought it their duty to kill any man they could and take away his money; the larger the number of men they killed, the better they thought they were. Ordinarily if a man goes out into the street and shoots down another man, he is apt to feel sorry for it, thinking that he has done wrong. But if the very same man, as a soldier in his regiment, kills not one but twenty, he is certain to feel glad and think that he has done his duty remarkably well. Therefore we see that it is not the thing done that defines a duty. To give an objective definition of duty is thus entirely impossible. Yet there is duty from the subjective side. Any action that makes us go Godward is a good action, and is our duty; any action that makes us go downward is evil, and is not our duty. From the subjective standpoint we may see that certain acts have a tendency to exalt and ennoble us, while certain other acts have a tendency to degrade and to brutalise us. But it is not possible to make out with certainty which acts have which kind of tendency in relation to all persons, of all sorts and conditions. There is, however, only one idea of duty which has been universally accepted by all mankind, of all ages and sects and countries, and that has been summed up in a Sanskrit aphorism thus: “Do not injure any being; not injuring any being is virtue, injuring any being is sin.”

The Bhagavad-Gita frequently alludes to duties dependent upon birth and position in life. Birth and position in life and in society largely determine the mental and moral attitude of individuals towards the various activities of life. It is therefore our duty to do that work which will exalt and ennoble us in accordance with the ideals and activities of the society in which we are born. But it must be particularly remembered that the same ideals and activities do not prevail in all societies and countries; our ignorance of this is the main cause of much of the hatred of one nation towards another. An American thinks that whatever an American does in accordance with the custom of his country is the best thing to do, and that whoever does not follow his custom must be a very wicked man. A Hindu thinks that his customs are the only right ones and are the best in the world, and that whosoever does not obey them must be the most wicked man living. This is quite a natural mistake which all of us are apt to make. But it is very harmful; it is the cause of half the uncharitableness found in the world. When I came to this country and was going through the Chicago Fair, a man from behind pulled at my turban. I looked back and saw that he was a very gentlemanly-looking man, neatly dressed. I spoke to him; and when he found that I knew English, he became very much abashed. On another occasion in the same Fair another man gave me a push. When I asked him the reason, he also was ashamed and stammered out an apology saying, "Why do you dress that way?" The sympathies of these men were limited within the range of their own language and their own fashion of dress. Much of the oppression of powerful nations on weaker ones is caused by this prejudice. It dries up their fellow feeling for fellow men. That very man who asked me why I did not dress as he did and wanted to ill-treat me because of my dress may have been a very good man, a good father, and a good citizen; but the kindliness of his nature died out as soon as he saw a man in a different dress. Strangers are exploited in all countries, because they do not know how to defend themselves; thus they carry home false impressions of the peoples they have seen. Sailors, soldiers, and traders behave in foreign lands in very queer ways, although they would not dream of doing so in their own country; perhaps this is why the Chinese call Europeans and Americans "foreign devils". They could not have done this if they had met the good, the kindly sides of Western life.

Therefore the one point we ought to remember is that we should always try to see the duty of others through their own eyes, and never judge the customs of other peoples by our own standard. I am not the standard of the universe. I have to accommodate myself to the world, and not the world to me. So we see that environments change the nature of our duties, and doing the duty which is ours at any particular time is the best thing we can do in this world. Let us do that duty which is ours by birth; and when we have done that, let us do the duty which is ours by our position in life and in society. There is, however, one great danger in human nature, viz that man never examines himself. He thinks he is quite as fit to be on the throne as the king. Even if he is, he must first show that he has done the duty of his own position; and then higher duties will come to him. When we begin to work earnestly in the world, nature gives us blows right and left and soon enables us to find out our position. No man can long occupy satisfactorily a position for which he is not fit. There is no use in grumbling against nature's adjustment. He who does the lower work is not therefore a lower man. No man is to be judged by the mere nature of his duties, but all should be judged by the manner and the spirit in which they perform them.

Later on we shall find that even this idea of duty undergoes change, and that the greatest work is done only when there is no selfish motive to prompt it. Yet it is work through the sense of duty that leads us to work without any idea of duty; when work will become worship — nay, something higher — then will work be done for its own sake. We shall find that the philosophy of duty, whether it be in the form of ethics or of love, is the same as in every other Yoga — the object being the attenuating of the lower self, so that the real higher Self may shine forth — the lessening of the frittering away of energies on the lower plane of existence, so that the soul may manifest itself on the higher ones. This is accomplished by the continuous denial of low desires, which duty rigorously requires. The whole organisation of society has thus been developed, consciously or unconsciously, in the realms of action and experience, where, by limiting selfishness, we open the way to an unlimited expansion of the real nature of man.

Duty is seldom sweet. It is only when love greases its wheels that it runs smoothly; it is a continuous friction otherwise. How else could parents do their duties to their children, husbands to their wives, and vice versa? Do we not meet with cases of friction every day in our lives? Duty is sweet only through love, and love shines in freedom alone. Yet is it freedom to be a slave to the senses, to anger, to jealousies and a hundred other petty things that must occur every day in human life? In all these little roughnesses that we meet with in life, the highest expression of freedom is to forbear. Women, slaves to their own irritable, jealous tempers, are apt to blame their husbands, and assert their own "freedom", as they think, not knowing that thereby they only prove that they are slaves. So it is with husbands who eternally find fault with their wives.

Chastity is the first virtue in man or woman, and the man who, however he may have strayed away, cannot be brought to the right path by a gentle and loving and chaste wife is indeed very rare. The world is not yet as bad as that. We hear much about brutal husbands all over the world and about the impurity of men, but is it not true that there are quite as many brutal and impure women as men? If all women were as good and pure as their own constant assertions would lead one to believe, I am perfectly satisfied that there would not be one impure man in the world. What brutality is there which purity and chastity cannot conquer? A good, chaste wife, who thinks of every other man except her own husband as her child and has the attitude of a mother towards all men, will grow so great in the power of her purity that there cannot be a single man, however brutal, who will not breathe an atmosphere of holiness in her presence. Similarly, every husband must look upon all women, except his own wife, in the light of his own mother or daughter or sister. That man, again, who wants to be a teacher of religion must look upon every woman as his mother, and always behave towards her as such.

The position of the mother is the highest in the world, as it is the one place in which to learn and exercise the greatest unselfishness. The love of God is the only love that is higher than a mother's love; all others are lower. It is the duty of the mother to think of her children first and then of herself. But, instead of that, if the parents are always thinking of themselves first, the result is that the relation between parents and children becomes the same as that between birds and their offspring which, as soon as they are fledged, do not recognise any parents. Blessed, indeed, is the man who is able to look upon woman as the representative of the motherhood of God. Blessed, indeed, is the woman to whom man represents the fatherhood of God. Blessed are the children who look upon their parents as Divinity manifested on earth.

The only way to rise is by doing the duty next to us, and thus gathering strength go on until we reach the highest state. A young Sannyâsin went to a forest; there he meditated, worshipped, and practiced Yoga for a long time. After years of hard work and practice, he was one day sitting under a tree, when some dry leaves fell upon his head. He looked up and saw a crow and a crane fighting on the top of the tree, which made him very angry. He said, "What! Dare you throw these dry leaves upon my head!" As with these words he angrily glanced at them, a flash of fire went out of his head — such was the Yogi's power — and burnt the birds to ashes. He was very glad, almost overjoyed at this development of power — he could burn the crow and the crane by a look. After a time he had to go to the town to beg his bread. He went, stood at a door, and said, "Mother, give me food." A voice came from inside the house, "Wait a little, my son." The young man thought, "You wretched woman, how dare you make me wait! You do not know my power yet." While he was thinking thus the voice came again: "Boy, don't be thinking too much of yourself. Here is neither crow nor crane." He was astonished; still he had to wait. At last the woman came, and he fell at her feet and said, "Mother, how did you know that?" She said, "My boy, I do not know your Yoga or your practices. I am a common everyday woman. I made you wait because my husband is ill, and I was nursing him. All my life I have struggled to do my duty. When I was unmarried, I did my duty to my parents; now that I am married, I do my duty to my husband; that is all the Yoga I practice. But by doing my duty I have become illumined; thus I could read your thoughts and know what you had done in the forest. If you want to know something higher than this, go to the market of such and such a town where you will find a Vyâdha (The lowest class of people in India who used to live as hunters and butchers.) who will tell you something that you will be very glad to learn." The Sannyasin thought, "Why should I go to that town and to a Vyadha?" But after what he had seen, his mind opened a little, so he went. When he came near the town, he found the market and there saw, at a distance, a big fat Vyadha cutting meat with big knives, talking and bargaining with different people. The young man said, "Lord help me! Is this the man from whom I am going to learn? He is the incarnation of a demon, if he is anything." In the meantime this man looked up and said, "O Swami, did that lady send you here? Take a seat until I have done my business." The Sannyasin thought, "What comes to me here?" He took his seat; the man went on with his work, and after he had finished he took his money and said to the Sannyasin, "Come sir, come to my home." On reaching home the Vyadha gave him a seat, saying, "Wait here," and went into the house. He then washed his old father and mother, fed them, and did all he could to please them, after which he came to the Sannyasin and said, "Now, sir, you have come here to see me; what can I do for you?" The Sannyasin asked him a few questions about soul and about God, and the Vyadha gave him a lecture which forms a part of the Mahâbhârata, called the Vyâdha-Gitâ. It contains one of the highest flights of the Vedanta. When the Vyadha finished his teaching, the Sannyasin felt astonished. He said, "Why are you in that body? With such knowledge as yours why are you in a Vyadha's body, and doing such filthy, ugly work?" "My son," replied the Vyadha, "no duty is ugly, no duty is impure. My birth placed me in these circumstances and environments. In my boyhood I learnt the trade; I am unattached, and I try to do my duty well. I try to do my duty as a householder, and I try to do all I can to make my father and mother happy. I neither know your Yoga, nor have I become a Sannyasin, nor did I go out of the world into a forest; nevertheless, all that you have heard and seen has come to me through the unattached doing of the duty which belongs to my position."

There is a sage in India, a great Yogi, one of the most wonderful men I have ever seen in my life. He is a peculiar man, he will not teach any one; if you ask him a question he will not answer. It is too much for him to take up the position of a teacher, he will not do it. If you ask a question, and wait for some days, in the course of conversation he will bring up the subject, and wonderful light will he throw on it. He told me once the secret of work, "Let the end and the means be joined into one." When you are doing any work, do not think of anything beyond. Do it as worship, as the highest worship, and devote your whole life to it for the time being. Thus, in the story, the Vyadha and the woman did their duty with cheerfulness and whole-heartedness; and the result was that they became illuminated, clearly showing that the right performance of the duties of any station in life, without attachment to results, leads us to the highest realisation of the perfection of the soul.

It is the worker who is attached to results that grumbles about the nature of the duty which has fallen to his lot; to the unattached worker all duties are equally good, and form efficient instruments with which selfishness and sensuality may be killed, and the freedom of the soul secured. We are all apt to think too highly of ourselves. Our duties are determined by our deserts to a much larger extent than we are willing to grant. Competition rouses envy, and it kills the kindliness of the heart. To the grumbler all duties are distasteful; nothing will ever satisfy him, and his whole life is doomed to prove a failure. Let us work on, doing as we go whatever happens to be our duty, and being ever ready to put our shoulders to the wheel. Then surely shall we see the Light!

3D Transistors !

A transistor is the fundamental building block of all electronic devices. A transistor can be defined as a device, which is used to amplify signals and power. Integrated circuits are used in making of chips inside electronic gadgets such as smart phones, laptops and so on. Researchers in Purdue and Harvard Universities have created a new type of transistor that will make the Integrated circuits more compact. This transistor is made from another material other than silicon and as the name suggest, a 3-D structure is given to the device compared to the conventional flat chips. Nano wires are used in these transistors instead of silicon so they will be more compact and more efficient. The nano wires used in this transistor are made from iridium-gallium-arsenide semiconductor.

Iridium-gallium-arsenide is replaced for silicon in this device. As they are elements from the 3rd and 5th group of the periodic table, they are collectively known as the III-V group semiconductors. These semiconductors are known to conduct electrons five times better than silicon. The mobility of this material is also known to be higher. All these characteristics have urged chip manufacturers to replace silicon with this semiconductor in the coming years.

The 3D transistor was made by a process termed ”top-down method” in which components of the transistor is etched. This method will gain huge acceptance as it is compatible with most of the industrial processes. In 2012, a new generation of integrated chips is believed to come into market in which transistors will be placed horizontally rather than vertically. This is the reason for the 3D effect posed by these transistors. Thus, this device is the world’s first 3D-gate-allround transistor.

The transistor consists of a gate by which rapid ON-OFF switching action is possible and helps in the direct flow of current. By the introduction of 3D transistors, it is estimated that this gate length will reduce from 45nm to 22 nm. The nano wires are coated with a dielectric, which acts as the gate. Further research is being conducted to reduce the gate length to 18 nm. The only option available is to make a thinner dielectric layer by a process called atomic deposition. A thinner dielectric layer offers greater speed, low voltage requirements and lower power consumption. The device has improved its clock speed to 20 GHz. This experiment was funded by the National Science foundation and Semiconductor research group. The latest development in this field was the design of a “finFET or fin Field Effect Transistor” in which the device has a fin like structure other than the conventional flat design.

By the introduction of 3D transistors computers will become faster, cooler and smarter. Intel is planning to release processors made from 3D transistor integrated chips in 2012. These chips are expected to be 10 times faster than the ones used now and will be more compact.

It is heard that a Japanese company named “Unisantis” is working with the researchers of Singapore’s Institute of micro electronics to develop a new 3D transistor called the SGT (Surrounding Gate Transistor) which will increase the clocking speed of the computers from 20 GHz to 50 GHz.
