MEMO FROM NARA...


“When you have money to buy a bicycle, you walk; when you have money to buy a scooter, you buy a bicycle; when you have money to buy a car, you buy a scooter” were the golden words of one of my Professors Dr. Kanakaraj David who taught me Entomology (Study of Insects) when I was a graduate student fifty years ago. I still remember those golden words which are stored in my brain. I repeatedly told this valuable advice to many of my students, friends and family members. Some of them really appreciated and some others were not heedful. However, I used to think over Dr. David’s suggestion many times. I found it more practical and more useful suggestion for everyone’s life. The moral of the statement is, simple and economic life can make one happy. In today’s world, no one wants to wait and get things, because loans are easily available to all. Thus there is plenty of money for buying a car straight away without using the legs to walk and riding a bicycle. Probably, Dr. David’s suggestion may not suit the present day set up of life. As you know that the advice is 50-year-old.

I know fully well that the loan business is an invention of the capitalists who are hungry for huge money. If we think of the interest we pay for the loans we take from nationalized or private banks, we really lose lot of money slowly and steadily. The loss of money on interest satisfies our greed to posses a car at once. The culture of walking and bicycling has disappeared from the minds of many middle-class and lower middle-class people. In fact, walking and bicycling are the best exercises to keep our body healthy. In addition, they are the cheapest exercises help to save the energy – petrol, electricity etc. Moreover, saving money for more urgent and needy things in life is a good habit. Because of saving we do not incline to buy unwanted things and accumulate as junks in our house. We all know how many such things are stored in every house without using them for decades or even for many decades. No one buys these junks paying the price we paid for them. Hence we give them for charity to get some mental peace. All those hard earned money is wasted? Is it really wasted? Or used for instant living?

JUST TO LAUGH...


Charles was getting annoyed and shouted to his wife," Hurry up or we'll be late."
"Oh, be quiet," replied his wife. "Haven't I been telling you for the last hour that I'll be ready in a minute?"

At an auction in Manchester a wealthy American announced that he had lost his wallet containing £10,000 and would give a reward of £100 to the person who found it. From the back of the hall a Scottish voice shouted, "I'll give £150!"

Two Americans are talking. One asks: "What's the difference between capitalism and communism?"
"That's easy" says the other one. "In capitalism man exploits man! In communism it is the other way around!"

What is the longest word in the English language?
"Smiles". Because there is a mile between its first and last letters!

IMPROVE YOUR BRAIN...


1. Convince yourself that you do have a good memory that will improve. Too many people get stuck here and convince themselves that their memory is bad, that they are just not good with names, that numbers just slip out of their minds for some reason. Erase those thoughts and vow to improve your memory. Commit yourself to the task and bask in your achievements — it's hard to keep motivated if you beat yourself down every time you make a little bit of progress.

2. Keep your brain active. The brain is not a muscle, but regularly “exercising” the brain actually does keep it growing and spurs the development of new nerve connections that can help improve memory. By developing new mental skills—especially complex ones such as learning a new language or learning to play a new musical instrument—and challenging your brain with puzzles and games you can keep your brain active and improve its physiological functioning.

3. Exercise daily. Regular aerobic exercise improves circulation and efficiency throughout the body, including in the brain, and can help ward off the memory loss that comes with aging. Exercise also makes you more alert and relaxed, and can thereby improve your memory uptake, allowing you to take better mental “pictures”

4. Reduce stress. Chronic stress, although it does not physically damage the brain, can make remembering much more difficult. Even temporary stresses can make it more difficult to effectively focus on concepts and observe things. Try to relax, regularly practice yoga or other stretching exercises, and see a doctor if you have severe chronic stress. -Pankaj Sharma

STUPID QUESTIONS...


You know that indestructible black box that is used on airplanes? Why don/t they make the whole plane out of that stuff?

If flying is so safe, why do they call the airport the terminal?

Why are they called apartments when they are all stuck together?

Why is ‘abbreviated’ such a long word?

PESSIMISM


Optimists are cheerful, accept challenges, believe that they can win and inspire others to succeed against all odds. However pessimism is not as bad as it is usually perceived. But at times, they over estimate their abilities and overlook / underestimate potential obstacles, and end with major failures. Realists on the other hand, take a more pragmatic approach. They focus on both positive and negative aspects. They pay reasonable attention to potential obstacles and rely on strengths to overcome them. Pessimists are closer to realists. They focus primarily on the negative possibilities and short falls. Their tendency to think this way, take their attention to those areas where their counterparts cannot reach. For example, a realist can anticipate problems that are logical or based on past experience. But a pessimist can take cues from various factors and relate them to the situation to conclude how they can affect it. However, to reach the right conclusion he should have good experience and knowledge. Though perceived as annoying, the value pessimists add to their team’s efforts is indispensable, especially if it is dealing with disaster control, risk assessment and the like.

CHALLENGES FOR 21st CENTURY...


1. Make solar energy economical.
2. Provide energy from fusion.
3. Develop carbon sequestration methods.
4. Manage nitrogen cycle.
5. Provide access to clean water.
6. Restore and improve urban infrastructure.
7. Advance healthcare informatics.
8. Engineer better medicines.
9. Reverse – engineer the brain.
10. Prevent nuclear terror.
11. Secure cyberspace.
12. Enhance vital reality.
13. Advance personalized learning.
14. Engineer the tools of scientific discovery.

Basically, there are four grand challenges: (i) of energy, environment, global warming, sustainability; (ii) improve medicine and healthcare delivery; (iii) reduce vulnerability to human and natural threats; (iv) expand and enhance human capability and joy. Meeting these challenges requires vision, science, imagination, boldness, priorities, policy, markets and perseverance.

· Where there is light, there is also darkness.
· Everybody’s life is a reality show.
· Everyone is a controversial person.
· Being fit translates to being slim, which translates to looking good.
· No one wants to grow old anymore.
· Looking and feeling good are the major goals of everyone.
· Big spending has become fashionable.
· Adversity is a fine incentive to write.
· Each successive government of Pakistan will be worse than its predecessor.
· One is not merely what one thinks and feels one is.
· Everything brings with it hope and joy.
· Make sure to always give credit where due.
· Principles should govern politics.
. In the mad race for numbers, quality takes a back seat.
. Harmony and non-violence are not just empty words; they are the fabric of many real lives.

CRYOGENIC TECHNOLOGY


Cryogenic technology involves the use of rocket propellants at extremely low temperatures. The combination of liquid oxygen and liquid hydrogen offers the highest energy efficiency for rocket engines that need to produce large amounts of thrust. But oxygen remains a liquid only at temperatures below minus 183oC and hydrogen at below minus 253oC. Building a rocket stage with an engine that runs on such propellants means overcoming engineering challenges. The

U. S. was the first country to develop cryogenic rocket engines. The Centaur upper stage, with RL-10 engines registered its first successful flight in 1963 and is still used on the Atlas V rocket. America’s early mastery of the technology paved the way for the J-2 engine, which powered the upper stages of the immensely powerful. Saturn V rocket that sent humans to the Moon. – N. Gopal Raj
