NanoTechnology

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, and the fabrication of devices with critical dimensions that lie within nano size range.

"I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big."
— Richard Feynman, Nobel Prize winner in physics

Today’s manufacturing methods are very crude at the molecular level. In the future, nanotechnology will let us snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics. This will be essential if we are to continue the revolution in computer hardware beyond about the next decade, and will also let us fabricate an entire new generation of products that are cleaner, stronger, lighter, and more precise.

Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes.

If we are to continue these trends we will have to develop a new manufacturing technology which will let us inexpensively build computer systems with mole quantities of logic elements that are molecular in both size and precision and are interconnected in complex and highly idiosyncratic patterns. Nanotechnology will let us do this.

For comparison, 10 nanometers is 1000 times smaller than the diameter of a human hair. A scientific and technical revolution has just begun based upon the ability to systematically organize and manipulate matter at nanoscale. Payoff is anticipated within the next 10-15 years.

Nanotechnology, in its advanced form, will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general.

Imagine a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread. Or a box no larger than a sugar cube that contains the entire contents of the the biggest Library on Earth. Or materials much lighter than steel that possess ten times as much strength.

Sweet Dreams beneath Bitter Chores

The sun resumed to his task again
piercing rays thru’ my blanket even.

Actually, I should be very busy-
but, I lay on my pallet very lazy.

I know I have to attend my college;
but my calendar is still in its old page.

Why is this thing always happening
troubling me early in the morning?

Never mind, I don’t let such thoughts creep;
For, I enjoy the sweet dreams in my sleep!


This was written during my engineering days,
when I used to pray for lengthy nights... :P

Positive Thinking

Here are some of the famous quotes by famous personalities on postive thinking.

"A man is but the product of his thoughts. What he thinks, he becomes."
-Mahatma Gandhi

"There is a little difference in people, but that little difference makes a big difference. The little difference is attitude. The big difference is whether it is positive or negative."
-W.Clement

"I am not afraid of tomorrow, for I have seen yesterday and I love today."
-William Allen

"Positive anything is better than negative nothing."
-Elbert Hubbard

"Positive thinking will let you do everything better than negative thinking will."
-Ziq Ziqlar

"A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty"
-Winston Churchill

"There is something positive about everything in life. Even a stopped clock shows correct time twice a day."
-Ravi Prasad Reddy

Having said that...
"Positive thoughts are not enough. There have to be positive feelings and positive actions."
-Ravi Prasad Reddy[me myself :-) ]
B +ve. Thats my blood group too.

Where are you?

Where are you? My dear, my love!
Where are you? My breath, my life!

I see you here,
I see you there,
I see you everywhere-
I find you nowhere!

You inspire me to be what I am.
You remind me to do what I should.
You make me scream, you make me cry.
You keep me quiet, you keep me happy.

I am waiting to meet you,
I am waiting to see you.
I am waiting to know you,
I am waiting to be with you.

Where are you? My dear, my love!
Where are you? My breath, my life!
