Graphene - email from Kamalini Kanapathippillai
We all think of ourselves as being well informed & some think they are experts in everything too. Here is wealth of fantastic information that I had never heard of. Did you?
It is a given fact that technology helps the world advance. As humans it's in our nature to investigate, innovate and solve problems. This curiosity means we make things, create things and develop new technologies. You can look back thousands of years for basic examples of technology pushing civilization forward.
Most people don't understand the rapid change technology has on their life... or the speed at which change occurs.
For example, the following are the five 'Great Ages' of human progress and their approximate duration:
You'll notice the length of each 'age' diminishes as technology improves. The computer industry calls this trend 'Moore's Law'. It dictates that computer processing power doubles every 18 months.
200 times stronger than steel...
150,000 times thinner than a human hair...
More flexible than a sheet of paper
You may have heard about Graphene. If you haven't, it's a newly discovered, very special refined form of graphite. It's a one-atom-thick sheet of densely packed carbon atoms arranged in a honeycomb lattice.
Take a look:
Put simply, it's a sheet of carbon atoms 150,000 times thinner than a human hair. Under a powerful microscope, it looks like chicken wire. But what's so special about it?
Everything
For starters, it's 200 times stronger than structural steel; it's so strong you could suspend an elephant from a single strand of Graphene, and the strand would not break.
It's extremely lightweight. Soon, everything from bicycles and boats to airplanes and cars could be made out of graphene composites. And when they are, their energy efficiency and durability could skyrocket.
But, that's just the beginning of what this new 'smart material' can do. Not only is it the strongest material researchers have ever tested, it's also one of the best conductors man has ever found. IBM has already created a graphene-based processor capable of executing 100 billion cycles per second. Researchers believe that in the future, a graphene credit card could store as much information as today's computers.
This one material alone could prove more
revolutionary than — and soon
REPLACE — plastic, Kevlar and the silicon chip
In fact, it's such a breakthrough that the first two scientists to successfully produce single-atom-thick crystals of graphene were awarded the 2010 Nobel Prize in Physics.
In just two years, over 200 companies from a wide array of industries have researched the magical potential of graphene:
Kiss goodbye to shattered screens
Samsung has already said its flexible displays should enter full-scale production later this year, and it expects to have a dozen more graphene based products on the market within the next five.
IBM, Nokia and Apple are hot on their heels too.
Touch screens, processor chips, casings, and batteries (in everything from PCs and HD TVs to tablets), mobile phones and hybrids could all be made with graphene.
It could change entire industries, economies, and our lives.
Imagine HD TVs as thin as wallpaper, Smart phones so skinny and flexible you can roll them up and put them behind your ear, and so durable you can beat them with a hammer!
Imagine if you could eliminate breast cancer or prostate tumors with a simple injection or by swallowing a graphene-charged pill.
Imagine if your house were strong enough to withstand a bush fire, and your windows processed enough solar energy to heat your home in winter and cool it in the summer. Or if your car were 6 times lighter and 20 times stronger.
The effects would be staggering!
Fuel-efficiency would shoot through the roof.
People would live longer, healthier lives.
Cars and airplanes would be lighter, faster and safer than ever before.
And electronics of every type would be launched into an era of unprecedented growth and evolution.
This is just a taste of the cutting-edge innovations coming in the Molecular Age, innovations that will reshape the future in the months and years ahead, and it's starting now.
You're looking at a simultaneous eruption of
new-age technologies that will alter our lives
on a scale not seen for 100 years
All this technological change and innovation will transform the world.
Spacecraft with the capacity to take us beyond our solar system into places and worlds never explored.

A teacher - email from jksw
On behalf of all our wonderful teachers. Each had something to impart, and did too.
jksw
A good/sensible reply from a Teacher?
From A School Principal's speech at a graduation..
He said "The Doctor wants his child to become a doctor.........
the Engineer wants his child to become an engineer......
The Businessman wants his ward to become CEO.....
BUT a teacher also wants his child to become one of them, as well..!!!!
Nobody wants to become a teacher BY CHOICE" ....Very sad but that's the truth.....!!!
The dinner guests were sitting around the table discussing life.
One man, a CEO, decided to explain the problem with education. He argued,
"What's a kid going to learn from someone who decided his best option in life was to become a teacher?"
To stress his point he said to another guest;
"You're a teacher, Bonnie. Be honest. What do you make?"
Teacher Bonnie, who had a reputation for honesty and frankness replied,
"You want to know what I make?
(She paused for a second, then began...)
"Well, I make kids work harder than they ever thought they could.
I make a C+ feel like the Congressional Medal of Honor winner.
I make kids sit through 40 minutes of class time when their parents can't
make them sit for 5 min. without an I- Pod, Game Cube or movie rental.
You want to know what I make?
(She paused again and looked at each and every person at the table)
I make kids wonder.
I make them question.
I make them apologize and mean it.
I make them have respect and take responsibility for their actions.
I teach them how to write and then I make them write.
Keyboarding isn't everything.
I make them read, read, read.
I make them show all their work in math.
They use their God given brain, not the man-made calculator.
I make my students from other countries learn everything they need
to know about English while preserving their unique cultural identity.
I make my classroom a place where all my students feel safe.
Finally, I make them understand that if they use the gifts they
were given, work hard, and follow their hearts, they can succeed in life
( Bonnie paused one last time and then continued.)
Then, when people try to judge me by what I make, with me knowing money is n't everything, I can hold my head up high and pay no attention because they are ignorant. You want to know what I make.
I MAKE A DIFFERENCE IN ALL YOUR LIVES, EDUCATING KIDS AND PREPARING THEM TO BECOME CEO's, AND DOCTORS AND ENGINEERS..........
What do you make Mr. CEO?
His jaw dropped; he went silent.
THIS IS WORTH SENDING TO EVERY PERSON YOU KNOW. Even all personal teachers like mother, father, brother, sister, coach and spiritual leader/teacher

Time to recall. Lest we forget.
Attached picture. How we looked after people post war 2009.
Advising the keen lady doctor in charge.
L>R Myself, lady doctor, limb fitting manager Karunasena and Mr Benjamin in
charge of Mobile camp.
Note the lack of hustle and bustle even in these early days post war.
Thatched roof. Beds. Wheelchair. The patients.
