A man feared his wife wasn’t hearing as well as she used to and he thought she might need a hearing aid. Not quite sure how to approach her, he called the family Doctor to discuss the problem. The Doctor told him there is a simple informal test the husband could perform to give the Doctor a better idea about her hearing loss.
Here’s what you do,” said the Doctor, “stand about 40 feet away from her, and in a normal conversational speaking tone see if she hears you. If not, go to 30 feet, then 20 feet, and s o on until you get a response.
“That evening, the wife is in the kitchen cooking dinner, and he was in the den. He says to himself, “I’m about 40 feet away, let’s see what happens.” then in a normal tone he asks, ‘Honey, what’s for dinner?” No response. So the husband moves to closer to the kitchen, about 30 feet from his wife and repeats, “Honey, what’s for dinner?”
Still no response. Next he moves into the dining room where he is
about 20 feet from his wife and asks, Honey, what’s for dinner?”
Again he gets no response so; He walks up to the kitchen door, about 10 feet away. “Honey, what’s for dinner?” Again there is no
response. So he walks right up behind her.
“Honey, what’s for dinner?”
“James, for the FIFTH time I’ve
said, CHICKEN!”
Moral of the story: The problem may not be with the other one as we always think, could be very much within us..!
A man was sitting on the edge of the bed observing
his wife turning back and forth, looking at herself in
the mirror.
Since her birthday was not far off, he asked her
what she’d like to have for her Birthday
I’d like to be six again, she replied, still looking
in the mirror.
On the morning of her Birthday, he arose early, made
her a nice big bowl of Lucky Charms, and then took
her to Six Flags theme park.
What a day ! He put her on every ride in the park; the
Death Slide, the Wall of Fear, the Screaming Monster
Roller Coaster… everything there was. Five hours
Later they staggered out of the theme park. Her head
was reeling and her stomach felt upside down.
He then took her to a McDonald’s where he ordered
her a Happy Meal with extra fries and a chocolate shake.
Then it was off to a movie, popcorn, a soda pop,
and her favorite candy, M&M’s. What a fabulous
adventure ! Finally she wobbled home with her
husband and collapsed into bed exhausted.
He leaned over his wife with a big smile and
lovingly asked, Well Dear, what was it like being six again?
Her eyes slowly opened and her _expression suddenly changed.
I meant my Dress Size, you dumb ass!
The moral of the story:
Even when a man is listening, he is going to get it wrong!
Last night I was discussing Self-Assembly with a friend of mine, who is working on Magnetic Logic Processor these days. He was busy writing n optimizing a Genetic Algorithm for self wiring in MRAM’s using magnetoresistance.
Inspired by nature we often tend to model the building blocks of any sophisticated technology. One can compare a wheel with a new leg, machine with a more efficient hand, a proposed theory of Neural Nets trying to simulate a human brain. A robotic vision somewat is trying to cope up with recognising objects. What more is left to explore ? Scientists never say die, the passion, the search is on. One of my friend, a researcher is dealing with organisation of nanoparticles to find ways to assemble in specific shapes, sizes or orientations. Earlier it was dealt in terms relating to viruses and proteins, polymers, molecules, semiconductors n metals. These days researchers are looking out for efficient ways to make microscopic machines, and faster n efficient electronics(say MRAM) which is based on Self-Assembly in hopes of putting things together with natural ease.
Introducing nanotechnology to future chip manufacturing, organizing key issues n putting them in context effieciently explains how the technologies copulate. The idea itself excites me. The future is gonna be great. What do u think ???
Today’s computer is shunted on three things.
1. Processors – manipulate computations
2. RAM – which retrieves info in quickly in realtime while pc is turned on.
3. Magnetic Disks – which store info when compu is shut
To facilitate the solution to problems created by volatile RAM chips, researchers are working on something they call MRAM (Magnetic Random Access Memory).
MRAM is based on magneto resistance n started back in 1950s but was overtaken by silicon chips due to performance, compactness n cost-effectiveness. Now researchers have found a way for single MRAM element to act as any of the four logic gates – AND, OR, NAND, NOR. Computer processors manipulate information by sending signals through logic gates. Future magnetic logic processors will contain many programmable magnetoresistive elements unlike today’s processor which has hardwired circuits that are dedicated to one type of logic operation. Today’s processor is optimised for different tasks – running a car brake system or running a personal computer by arranging these logic gates in certain order. Jus think the ease of getting it programmed on the fly can do so many wonders.
MRAM (Magnetic Random Access Memory) is fast compared to RAM chips, n is also non volatile, which means that it retains info even when computer is turned off. Researchers from Germany say that it is also possible to use MRAM for computational stuff. Since the memory is configurable, computing circuits formed from it can be adjusted in realtime to optimise processing for a particular application. This reprogrammability n non volatility feature is expected to increase the computational efficiency for all kinda processors relating to the work done on them. Your computer will learn bout what applications you use often, n the optimize for running of that particular process in real time ie. straight what HP states in its commercial. Your computer is personal again. MRAM is expected to hit the market next year. I ll try n get my hands on a copy when that happens.
