 நான் பட்ட கஷ்டங்கள் என் குழந்தைகள் படக்கூடாது” – இது நல்லதா ?

கழுகுகள் நமக்கு கற்றுதரும் பாடம்!!!

பறவைகளில் கழுகுகள் மிக சக்தி வாய்ந்தவை. அவை மிக உயரமாகப் பறக்கக் கூடியவை. அவற்றைவலிமை மற்றும் தைரியம் ஆகியவற்றின் சின்னமாகக் கருதுகின்றோம். ஆனால் அந்தக் கழுகுகளின்பறக்கும் சாகச சக்திகளும், வலிமையும், தைரியமும் பிறப்பிலேயே வருபவை அல்ல. அவைகழுகுகளால் ஒரு கட்டத்தில் கற்றுக் கொள்ளப்படுபவை தான்.

குஞ்சுகளாகக் கூட்டில் சுகமாக, பாதுகாப்பாக இருக்கும் போது கழுகுகள் பலவீனமாகவேஇருக்கின்றன. அவை அப்படியே சுகமாகவும், பாதுகாப்பாகவுமே இருந்து விட்டால் வலிமையாகவும்,சுதந்திரமாகவும் மாறுவது சாத்தியமல்ல. எனவே குஞ்சுகளாக இருக்கும் போது வேண்டியஉணவளித்து, பாதுகாப்பாக வைத்திருக்கும் தாய்ப்பறவை குஞ்சுகள் பறக்க வேண்டிய காலம் வரும்போது மாறி விடுகின்றது.

முதலில் கூடுகளில் மெத்தென இருக்கும் படுக்கையினைக் கலைத்து சிறு குச்சிகளின் கூர்மையானபகுதிகள் வெளிப்படும்படி செய்து கூட்டை சொகுசாகத் தங்க வசதியற்றபடி செய்து விடுகின்றது. பின்தன் சிறகுகளால் குஞ்சினை அடித்து இருக்கும் இடத்தை விட்டுச் செல்லத் தூண்டுகின்றது. தாய்ப்பறவையின் இம்சை தாங்க முடியாத கழுகுக்குஞ்சு கூட்டின் விளிம்புவரை வந்து நிற்கின்றது. அதுவரை பறந்தறியாத குஞ்சு கூட்டின் வெளியே உள்ள உலகத்தின் ஆழத்தையும் உயரத்தையும்விஸ்தீரணத்தையும் பார்த்து மலைத்து நிற்கின்றது.

அந்தப் பிரம்மாண்டமான உலகத்தில் தனித்துப் பயணிக்க தைரியமற்று பலவீனமாக நிற்கின்றது.அது ஒவ்வொரு குஞ்சும் தன் வாழ்க்கையில் சந்தித்தாக வேண்டிய ஒரு முக்கியமான தவிர்க்கமுடியாத கட்டம். அந்த நேரத்தில் அந்தக் குஞ்சையே தீர்மானிக்க விட்டால் அது கூட்டிலேயேபாதுகாப்பாகத் தங்கி விட முடிவெடுக்கலாம். ஆனால் கூடு என்பது என்றென்றைக்கும் பாதுகாப்பாகத்தங்கி விடக் கூடிய இடமல்ல. சுயமாகப் பறப்பதும் இயங்குவதுமே ஒரு கழுகுக்கு நிரந்தரப் பாதுகாப்புஎன்பதைத் தாய்ப்பறவை அறியும்.

அந்தக் கழுகுக்குஞ்சு கூட்டின் விளிம்பில் என்ன செய்வதென்று அறியாமல் வெளியே எட்டிப்பார்த்துக் கொண்டு இருக்கும் அந்தக் கட்டத்தில் தாய்ப்பறவை அந்தக் குஞ்சின் உணர்வுகளைலட்சியம் செய்யாமல் குஞ்சை கூட்டிலிருந்து வெளியே தள்ளி விடுகிறது. அந்த எதிர்பாராததருணத்தில் கழுகுக்குஞ்சு கஷ்டப்பட்டு சிறகடித்துப் பறக்க முயற்சி செய்கின்றது. முதல்முறையிலேயே கற்று விடும் கலையல்ல அது.

குஞ்சு காற்றில் சிறகடித்துப் பறக்க முடியாமல் கீழே விழ ஆரம்பிக்கும் நேரத்தில் தாய்க்கழுகுவேகமாக வந்து தன் குஞ்சைப் பிடித்துக் கொள்கிறது. குஞ்சு மீண்டும் தாயின் பிடியில் பத்திரமாகஇருப்பதாக எண்ணி நிம்மதியடைகிறது. அந்த நிம்மதி சொற்ப நேரம் தான். தன் குஞ்சைப் பிடித்துக்கொண்டு வானுயரப் பறக்கும் தாய்க்கழுகு மீண்டும் அந்தக் கழுகுக்குஞ்சை அந்தரத்தில் விட்டுவிடுகிறது. மறுபடி காற்று வெளியில் சிறகடித்துப் பறக்க வேண்டிய நிர்ப்பந்தத்திற்கு அந்தக் குஞ்சுஉள்ளாகிறது.

இப்படியே குஞ்சை வெளியே தள்ளி விடுவதும், காப்பாற்றுவதுமாகப் பல முறை நடக்கும் இந்தப்பயிற்சியில் கழுகுக் குஞ்சின் சிறகுகள் பலம் பெறுகின்றன. காற்று வெளியில் பறக்கும் கலையையும்விரைவில் கழுகுக்குஞ்சு கற்றுக் கொள்கிறது. அது சுதந்திரமாக, ஆனந்தமாக, தைரியமாகவானோக்கிப் பறக்க ஆரம்பிக்கிறது.

கழுகுக் குஞ்சு முதல் முறையாக கூட்டுக்கு வெளியே உள்ள உலகத்தின் பிரம்மாண்டத்தைக் கண்டுபயந்து தயங்கி நிற்கும் அந்தத் தருணத்தில் தாய்க்கழுகு அதனை முன்னோக்கித் தள்ளியிராவிட்டால் அந்த சுதந்திரத்தையும், ஆனந்தத்தையும், தைரியத்தையும் அந்தக் கழுகுக்குஞ்சு தன்வாழ்நாளில் என்றென்றைக்கும் கண்டிருக்க முடியாது. பறக்க அறியாத அந்தக் குஞ்சை கூட்டினைவிட்டு வெளியே தாய்ப்பறவை தள்ளிய போது அது ஒருவிதக் கொடூரச் செயலாகத் தோன்றினாலும்பொறுத்திருந்து விளைவைப் பார்க்கும் யாருமே அந்தச் செயல் அந்தக் குஞ்சிற்குப் பேருதவி என்பதைமறுக்க முடியாது

ஒவ்வொரு புதிய சூழ்நிலையும் யாருக்கும் ஒருவித பதட்டத்தையும், பயத்தையும் ஏற்படுத்தக்கூடும். ஆனால் அந்தக் காரணத்திற்காகவே அந்த சூழ்நிலைகளையும், அனுபவத்தையும் மறுப்பதுவாழ்வின் பொருளையே மறுப்பது போலத் தான். கப்பல் துறைமுகத்தில் இருப்பது தான் அதற்குமுழுப்பாதுகாப்பாக இருக்கலாம். ஆனால் கப்பலை உருவாக்குவது அதை துறைமுகத்தில் நிறுத்திவைக்க அல்ல. கப்பலின் உபயோகமும் அப்படி நிறுத்தி வைப்பதில் இல்லை. கழுகிற்கும்,கப்பலுக்கும் மட்டுமல்ல, மனிதனுக்கும் இந்த உண்மை பொருந்தும்

தாய்க்கழுகு தான் குஞ்சாக இருக்கையில் முதல் முதலில் தள்ளப்பட்டதை எண்ணிப்பார்த்து “நான்பட்ட அந்தக் கஷ்டம் என் குஞ்சு படக்கூடாது. என் குஞ்சிற்கு அந்தப் பயங்கர அனுபவம் வராமல்பார்த்துக் கொள்வேன்” என்று நினைக்குமானால் அதன் குஞ்சு பலவீனமான குஞ்சாகவே கூட்டிலேயேஇருந்து இறக்க நேரிடும். ஆனால் அந்த முட்டாள்தனத்தை தாய்க்கழுகு செய்ததாக சரித்திரம்இல்லை

அந்த தாய்க்கழுகின் அறிவுமுதிர்ச்சி பல பெற்றோர்களிடம் இருப்பதில்லை. “நான் பட்ட கஷ்டங்கள்என் குழந்தைகள் படக்கூடாது” என்று சொல்லக்கூடிய பெற்றோர்களை இன்று நாம் நிறையவேபார்க்கிறோம். ஒரு காலத்தில் கூட்டுக் குடும்பமும் அதில் கும்பலாகக் குழந்தைகளும் இருந்த போதுபெற்றோர்களுக்குத் தங்கள் ஒவ்வொரு குழந்தை மீதும் தனிக்கவனம் வைக்க நேரம் இருந்ததில்லை.அதற்கான அவசியம் இருப்பதாகவும் அவர்கள் நினைத்ததில்லை.

ஆனால் இந்தக் காலத்தில் ஓரிரு குழந்தைகள் மட்டுமே உள்ள நிலையில் பெற்றோர்கள் தங்கள்குழந்தைகளுக்கு மிக நல்ல வாழ்க்கை அமைத்துக் கொடுக்க வேண்டும் என்பதில் குறியாகஇருக்கிறார்கள். அதில் தவறில்லை. ஆனால் தான் பட்ட கஷ்டங்கள் எதையும் தங்கள் குழந்தைகள்படக்கூடாது என்று நினைக்கும் போது பாசமிகுதியால் அவர்கள் அந்தக் கஷ்டங்கள் தந்த பாடங்களின்பயனைத் தங்கள் பிள்ளைகளுக்கு அளிக்கத் தவறி விடுகிறார்கள். அதற்காக “நான் அந்தக் காலம்பள்ளிக்கூடம் செல்ல பல மைல்கள் நடந்தேன். அதனால் நீயும் நட” என்று பெற்றோர்கள் சொல்லவேண்டும் என்று சொல்லவில்லை. வசதிகளும், வாய்ப்புகளும் பெருகி உள்ள இந்தக் காலத்தில்அப்படிச் சொல்வது அபத்தமாகத் தான் இருக்கும்.

இன்றைய நவீன வசதி வாய்ப்புகளின் பலனை பிள்ளைகளுக்கு அளிப்பது அவசியமே. தேவையேஇல்லாத கஷ்டங்களை பிள்ளைகள் படத் தேவையில்லைதான். ஆனால் ‘எந்தக் கஷ்டமும், எந்தக்கசப்பான அனுபவமும் என் பிள்ளை படக்கூடாது’ என்று நினைப்பது அந்தப் பிள்ளையின்உண்மையான வளர்ச்சியைக் குலைக்கும் செயலே ஆகும்.

வாழ்க்கையில் சில கஷ்டங்களும், சில கசப்பான அனுபவங்களும் மனிதனுக்குஅவசியமானவையே. அவற்றில் வாழ்ந்து தேர்ச்சி அடையும் போது தான் அவன் வலிமைஅடைகிறான். அவற்றிலிருந்து பாதுகாப்பளிப்பதாகப் பெற்றோர் நினைப்பது அவனுக்குவாழ்க்கையையே மறுப்பது போலத் தான். சில கஷ்டங்கள் பிள்ளைகள் படும் போதுபெற்றோர்களுக்கு மனம் வருத்தமாக இருக்கலாம். ஆனால் கஷ்டங்களே இல்லாமல் இருப்பதுவாழ்க்கை அல்ல, வாழ்க்கையின் அர்த்தமும் அல்ல, அது சாத்தியமும் அல்ல.

Message For the Day…” Your Soul [Divine Self ] is the Real ‘You’ ….”

NatarajanLeave a comment

The human body is a cover, a receptacle for the Atma. Elements like water and wind are intimately bound up with the body. Therefore, theAtma Principle, which is the core, is not cognised. People have lost awareness of this Principle, which is Truth. The Atma is in the body, but not of it. The Atma Principle, though active in the body, does not belong to the body. The ability of the eyes to see and the ears to hear are given by the Atma. The eyes and ears are sustained by the Omni-Consciousness, the Divine Principle. Your Soul (Divine Self) is the real ‘You’, the Will (Sankalpa). The elements (ether, wind, fire, water, and earth) that constitute the cosmos operate only as prompted by the supreme wisdom, which energizes them. The entire world of living beings – both fixed and moving are sustained by supreme wisdom. That supreme wisdom is Atma, the Brahman and the visible, objective world.

NatarajanLeave a comment

 

How difficult is it to film a running car sitting in another car? Pretty difficult. But this video mission has crossed all levels of precision and perfection by capturing the launch and the flight of India’s nuclear-capable sub sonic cruise missile called Nirbhay. The missile is being developed by India’s DRDO with features like wing development and a turbofan engine. It carries either conventional or a nuclear payload while flying to the target.

This video uploaded by Anantha Krishnan M. is from the last successful test and is shot from an IAF Jaguar plane. We salute the pilot and the camera person for a brilliant footage!

NatarajanLeave a comment

 

The Ghirardi Compton Oak has been a piece of League City’s history for over 100 years. The tree stands 56 feet tall, has a canopy that is over 100 feet wide, and is 135 inches around. It also weighs an incredible 518,000 pounds. A county road widening project put the future of the Ghirardi Oak in jeopardy. Council voted to use park dedication funds to hire Hess Landscaping Construction to move the majestic oak. A project that took them just under a month to complete. Watch the incredible process from start to finish in this video.

Track for this video: http://www.istockphoto.com/stock-audio-19114250­-in-love-full-length.php

On March 22, 2014 the City of League City held an opening ceremony for the new Ghirardi WaterSmart Park. The Ghirardi WaterSmart Park is a three acre passive park which is dedicated to teaching citizens ways to conserve their water use at home. It consists of community garden areas, native planting displays, a rain garden, a theater area as an outdoor classroom as well, a small nature play area, park and maintenance buildings, picnic area, decomposed granite trails, wooden boardwalks and footbridges interpretive signage, green roof kiosk and water cistern. The park was built around the previously relocated and internationally famous Ghirardi Oak. See photos from the grand opening here:https://www.facebook.com/media/set/?s…

Here is what a Pilot Thinks When the Aircraft loses all of its Engines in the Mid Air….

NatarajanLeave a comment

Last weekend, Singapore Airlines Flight 836 was traveling from Singapore to Shanghai when the twin-engine Airbus A330-343 lost power on both engines over the South China Sea.

Fortunately, the pilots were able to restore power to the engines, and the flight was able to continue on to its destination.

No injuries have been reported.

Modern turbofan engines are very robust pieces of engineering and tend to be incredibly reliable.

That makes last weekend’s incident an exceedingly rare event.

In fact, experienced A330 pilot Karlene Petitt told Business Insider that in her years flying the popular jet, she has never encountered, in pilot parlance, a “dual flameout.”

So what is an airline pilot thinking when the engines on his or her plane inexplicably lose power?

“What would go through my mind is fly the plane and do everything I can to get the engines started,” Petitt said in an email. “That would be the only thing to think about.”

In the cockpit, pilots are equipped with reference guides which provides guidance and checklists for a wide variety of operational situations – including the loss of power on all engines.

At cruising altitudes – 39,000 ft. in the case of the Singapore jet – the air is very thin and there may not be enough oxygen to get the engines to relight.

However, according to Petitt, “Normally when you get down around 24,000 feet you should be able to get one started because of the denser air at that altitude.”

In the case of Singapore Flight 836, the airliner lost 13,000 feet of altitude before the pilots were able to get the engines going again.

According to Petitt, she would only think about looking for a landing location after realizing she wouldn’t be able to get the engines going.

Depending on how high and how far the airplane is from an airport, the pilot would then determine what would be the appropriate course of action

In past incidents, pilots have chosen a variety of strategies.

In 1983, Air Canada Flight 143 going from Montreal to Edmonton ran out of fuel midway through the flight after the ground crew miscalculated the amount needed for the trip. The pilots were able to glide the twin-engine Boeing 767-200 jet to safety at a retired Canadian military runway that had been turned into a race track.

In 2001, an Air Transat Airbus A330 traveling from Toronto to Lisbon developed a fuel leak while flying over the Atlantic Ocean. The widebody jet lost all power, but the pilots were able to glide to an airport in the Azores Islands.

Miracle on the Hudson

Most famously, US Airways flight 1549 lost both of its engines after colliding with a flock of geese while taking off from New York’s LaGuardia Airport. Due to the low altitude, the pilots didn’t have time to complete the engine restart procedure. Miraculously, Captain Sully Sullenberger was able to successfully guide the Airbus A320 down in the middle of the Hudson River.

In these instances, the pilots were able to safely land their planes with few injuries to the passengers and crew.

“Pilots never stop flying the plane,” Petitt reiterated. “No matter what, we will do what it takes.”

Message For the Day…” God is the Cosmic Director and all of us are Mere Actors…”

NatarajanLeave a comment

You pray to God for trivial worldly things. Distinguish clearly between earthly happiness and divine bliss. Ask for selfless love, which you do not have, but He has in plenty. Pray for love, peace and bliss. God is the embodiment of bliss; His love is supreme without a parallel. He knows what is good for you and will give it. He is a witness to all your thoughts, words and actions. Therefore surrender wholeheartedly unto Him, and lead an ideal life. You are all embodiments of the Divine. So love all and never hurt anyone. If you harm anyone, you are harming the Divine. Love is as vital for a human as fire is vital for a lump of coal to sparkle. Get rid of all your weaknesses by concentrating on Divine Love, as grace is ever flowing and confers the greatest strength. God is the Cosmic Director and all humans are mere actors. So perform your role to please Him!

Few Accidental Discoveries that Changed the world….

NatarajanLeave a comment

Scientist Lab

In many ways, modernity can be viewed as little more than the the product of centuries of dumb luck. As you are about to see, some of the world’s most significant milestones were the result of nothing more than happy accidents.

Accidental Discoveries: Penicillin

Penicillin Pills

Scottish biologist Alexander Fleming changed modern medicine and saved countless lives by not being a very tidy man. Fleming left for vacation in 1928, failing to clean up his lab beforehand. When he returned, he noticed that some of his Petri dishes had developed mold that prevented bacteria to grow on them.

Accidental Discoveries Penicillin

Correctly guessing that the mold had antibacterial properties, Fleming went to work on identifying the culture – Penicillium notatum. From that, the scientist was able to extract penicillin and revolutionize the world of antibiotics.

Accidental Discoveries Penicillin Advertising

It should be noted that it took another decade before other scientists found a way to create a stable strain of penicillin that could be mass-produced. Likewise, Fleming wasn’t the first person to see the potential of moldy cultures. Other prominent scientists such as Louis Pasteur and Joseph Lister also realized that certain molds could inhibit bacteria growth, not to mention the fact that moldy bread was a traditional infection remedy since ancient times.

The Big Bang Theory

Accidental Discoveries Big Bang

We aren’t actually talking about the discovery of the Big Bang theory itself, but rather of the cosmic microwave background (CMB), or the radiation that the Big Bang left behind. George Gamow predicted its existence in the 1940s but it wasn’t until 1964 that two radio astronomers, Robert Wilson and Arno Penzias, discovered it completely by chance.

Accidental Discoveries Big Bang Astronomers

For their work, Wilson and Penzias won the Nobel Prize in 1978 Source: One Minute Astronomer
Penzias and Wilson were working at Bell Labs in New Jersey and experimenting with a state-of-the-art horn antenna when they picked up some weird interference. At first, they thought this was due to something way less exciting than the CMB – pigeons. However, once they cleared the nest, they noticed that the interference remained. It could only be CMB.

Accidental Discoveries Big Bang Antenna

And thus the two astronomers discovered the first compelling evidence for the veracity of the Big Bang theory. At that time, the origins of the universe were in even hotter debate than today, with camps divided primarily by those who believed in an expanding universe (first put forward by Belgian priest/scientist Georges Lemaitre and later supported by Russian physicist George Gamow) or steady-state theory, the idea of a universe that always was and always will be. The discovery of the CMB tipped the scales in the Big Bang’s favor.

X-Rays

X Ray Hands

In 1895, German physicist Wilhelm Röntgen was doing some simple experiments with a cathode ray tube. At one point, he noticed that the tube was lighting a piece of fluorescent cardboard in the room even though there was a screen between them. Röntgen unsuccessfully tried to block the rays and eventually thought of sticking his hand in front of the tube, revealing the bones inside it. He had just discovered X-rays.

X Ray Rontgen

To be fair, others were aware of the effects of X-rays before Röntgen, but he was the one to study them systematically. He also gave them their name, even though they were referred to as Röntgen rays for decades following his discovery.

Accidental Discoveries X Ray

Röntgen went to work on improving the imaging process by replacing the screen with a photographic plate so the images would be clearer. The first medical x-ray ever taken was of his wife’s hand, which Röntgen presented to the scientific community. Pretty soon x-ray technology became an international medicinal staple.

 

Radioactivity

Accidental Discoveries Radioactivity Sign

One happy accident often leads to another. That was the case with French scientist Henri Becquerel, who, after being inspired by Röntgen’s work, started researching phosphorescence in 1896. Becquerel thought that phosphorescence was responsible for the x-ray effect so he tried exposing some photographic plates to phosphorescent salts in order to confirm it.

Accidental Discoveries Radioactivity Becquerel

None of the materials used ended up having an effect, save for one: uranium salts. And even still, that discovery was made completely by chance. Becquerel considered sunlight to be essential to the experiment, and it was cloudy on the day he planned to test the uranium salts. Becquerel stuck everything in a drawer and waited to experiment another day, only to find days later that the uranium salts caused the photographic plate to blacken in spite of the darkness.

Accidental Discoveries Radioactivity Plate

Becquerel had wrapped the plates in paper so they were never in direct contact with the uranium salts, which meant that some unknown form of radiation capable of passing through solid objects was responsible for this event, not phosphorescence. Becquerel had stumbled upon radioactive decay or, as more know it, radioactivity.

Wearable Pacemaker

With over 350 patents to his name, it’s a wonder that Wilson Greatbatch is not a household name. But of all his innovations, the wearable pacemaker is undoubtedly the most highly acclaimed.

Accidental Discoveries Pacemaker

In 1956, Greatbatch was an electrical engineer working to build a heart rhythm-recording device. In a serendipitous moment of inattention, he reached into a box of spare parts for a resistor, but grabbed the wrong size. Greatbatch realized this after installing it, but he also noticed that the completed circuit produced an electric pulse at a speed of 1.8 times per second.

Accidental Discoveries Pacemaker Implanted

That’s roughly as fast as the heart beats, something Greatbatch immediately picked up on. He realized that the electrical stimuli could be used to assist a weak heart and went to work on shrinking down his device. In 1958 he successfully inserted a pacemaker into a dog, but it was left to a Minneapolis medical company to develop wearable pacemaker for humans that same year.
