Myth of cockroach’s immunity to nuclear
irradiation busted
Cockroaches survived much more than humans
Fruit flies, flour beetles tougher than cockroaches
Last year, the Myth Buster TV team from the Discovery Channel
announced that they would find out experimentally whether
cockroaches would be the only living
form to survive a nuclear war (The Hindu, November, 1, 2007). On
January 30, this year (Episode number 97), the team busted the
myth which was in their priority list from day one.
The announcement that the myth buster team will conduct an
experiment received wide media coverage; surprisingly, the media
virtually ignored the results of the experiment.
The staff of the Pacific Northwest National Laboratory at Hanford
site (U.S.) assisted the team to expose three groups of German
cockroaches (50 each) to 1,000, 10,000 and 100,000 rads
of gamma radiation using an irradiator located in the basement of a
building at Hanford. The fourth group of 50 cockroaches served as
control... (Rad is a unit of radiation dose; a dose of 450 rads may kill
50 per cent of the persons exposed) They exposed similar groups of
50 flour beetles and 100 fruit flies which represented other living forms
to similar doses. Many bugs initially survived after receiving 1,000 rads
and 10,000 rads . However, only some flour beetles survived after
receiving a dose of 100,000 rads. Fruit flies and flour beetles are found
to be tougher than cockroaches. For instance, on the second day after
receiving 100,000 rads, all the cockroaches died; 40 per cent
of the fruit flies and 90 per cent of the flour beetles survived. The
survivors will be infertile.
“While cockroaches survived much more than the humans would,
the other two test subjects did better than the cockroach,” the TV
channel declared. They concluded that they busted the myth since,
more life forms than cockroaches survived!
The spectators’ reactions to the TV programme, revealed how
differently the common man understands radiation related concepts.
Is it safe to go into the room after cobalt irradiated the bugs? A viewer
wanted to know. The questioner wrongly felt that irradiation with
cobalt will leave the room radioactive!
One viewer objected to the use of cobalt radiation to irradiate
the bug. “Consideringthat the myth was “will cockroaches survive
a nuclear blast” shouldn’t they have used uranium-238?” he
queried. “I believe that this is the substance used in modern day
nuclear weapons,” he argued. (Obviously he did not understand
the difference between radiation from a nuclear weapon and that
from uranium-238).
It was equally wrong on the part of the TV channel to claim that
they are exposing the insects to a nuclear blast when they actually
exposed the bugs to gamma radiation from a cobalt source. The
survivability of cockroaches in a nuclear war has been a topic of
interest for several years.
Based on the work of Hassett and Jenkins (Nucleonics, 1952),
Professor John Moulder, Professor of Radiation Biology, Medical
College of Wisconsin, noted that about900-1,000 Gys are needed
to kill a cockroach (one Gy= 100rads); more dose is
required if the dose is delivered at a slower rate. The claim that
not enough scientific data are available is not true.
In 1957, Drs Wharton and Wharton found that 1,000 rad can
interfere with the fertility of cockroach. In 1963, Drs Ross and
Cochran found that a low dose of 6,400 rad would kill 93 per cent
of immature German cockroaches.
Inspite of such unimpeachable evidence on its
radiation-vulnerability, the myths about this unlovable creature
may survive, not withstanding the fame and popularity of the
‘Myth Busters.’

Oh God, Please! Make me women
OH GOD, Please ! Make me women
He wanted her to see what he went through. So he prayed:
" Dear Lord: I go to work every day and put in 8 hours while my wife merely stays at home.
I want her to know what I go through, so please allow her body to switch with mine for a day. Amen.
God, in his infinite wisdom, granted the man's wish.
The next morning, sure enough, the man awoke as a woman.
He arose, cooked breakfast for his mate, awakened the kids,
Set out their school clothes, fed them breakfast, packed their lunches,
Drove them to school, came home and picked up the dry cleaning, took it to the cleaners
And stopped at the bank to make a deposit, went grocery shopping,
Then drove home to put away the groceries,
Paid the bills and balanced the checkbook.
He cleaned the cat's litter box and bathed the dog.
Then it was already 1 P.M.and he hurried to make the beds,do the laundry, vacuum, dust, and sweep and mop the kitchen floor.
Ran to the school to pick up the kids and got into an argument with them on the way home.
Set out milk and cookies and got the kids organized to do their homework,
Then set up the ironing board and watched TV while he did the ironing.
At 4:30 he began peeling potatoes and washing vegetables for salad, breaded the pork chops and snapped fresh beans for supper.
After supper, he cleaned the kitchen, ran the dishwasher, folded laundry, bathed the kids, and put them to bed. At 9 P.M. He was exhausted
And, though his daily chores weren't finished, he went to bed.where he was expected to make love, which he managed to get through without complaint.
The next morning, he awoke and immediately knelt by the bed and said, Lord,
I don't know what I was thinking. Iwas so wrong to envy my wife's being able to stay home all day. Please, oh please, let us trade back."
The Lord, in his infinite wisdom, replied, "My son, I feel you have learned
Your lesson and I will be happy to change things back to the way they were.
You'll just have to wait nine months,though. You got pregnant last night."
Red Marbles
I was at the corner grocery store buying some early potatoes.
I noticed a small boy, delicate of bone and feature, ragged but clean, hungrily apprizing a basket of freshly picked green peas.
I paid for my potatoes, but was also drawn to the display of fresh green peas.
I am a pushover for creamed peas and new potatoes. Pondering the peas, I couldn't help overhearing the conversation between Mr. Miller (the store owner) and the ragged boy next to me.
'Hello Barry, how are you today?'
'H'lo, Mr. Miller. Fine, thank ya. Jus' admirin' them peas. They sure look good.'
'They are good, Barry. How's your Ma?'
'Fine. Gittin' stronger alla' time.'
'Good. Anything I can help you with?'
'No, Sir. Jus' admirin' them peas.'
'Would you like take some home?' asked Mr. Miller.
'No, Sir. Got nuthin' to pay for 'em with.'
'Well, what have you to trade me for some of those peas?'
'All I got's my prize marble here.'
'Is that right? Let me see it' said Miller.
'Here 'tis. She's a dandy.'
'I can see that. Hmmmmm, only thing is this one is blue and I sort of go for red. Do you have a red one like this at home?' the store owner asked.
'Not exactly but almost.'
"Tell you what. Take this sack of peas home with you and next trip this way let me look at that red marble", Mr. Miller told the boy.
"Sure will. Thanks Mr. Miller."
Mrs. Miller, who had been standing nearby, came over to help me.
With a smile she said, 'There are two other boys like him in our community, all three are in very poor circumstances. Jim just loves to bargain with them for peas, apples, tomatoes, or whatever.
When they come back with their red marbles, and they always do, he decides he doesn't like red after all and he sends them home with a bag of produce for a green marble or an orange one, when they come on their next trip to the store.'
I left the store smiling to myself, impressed with this man.
A short time later I moved to Colorado , but I never forgot the story of this man, the boys, and their bartering for marbles.
Several years went by, each more rapid than the previous one.
Just recently I had occasion to visit some old friends in that Idaho community, and while there, I learned that Mr. Miller had died.
They were having his visitation that evening, and knowing my friends wanted to go, I agreed to accompany them.
Upon arrival at the mortuary, we fell into line to meet the relatives of the deceased, and to offer whatever words of comfort we could.
Ahead of us in line were three young men.
One was in an army uniform and the other two wore nice haircuts, dark suits and white shirts...all very professional looking.
They approached Mrs. Miller, standing composed and smiling by her husband's casket.
Each of the young men hugged her, kissed her on the cheek, spoke briefly with her and moved on to the casket.
Her misty light blue eyes followed them as, one by one, each young man stopped briefly and placed his own warm hand over the cold pale hand in the casket.
Each left the mortuary awkwardly, wiping his eyes.
Our turn came to meet Mrs. Miller. I told her who I was and reminded her of the story from those many years ago and what she had told me about her husband's bartering for marbles.
With her eyes glistening, she took my hand and led me to the casket.
'Those three young men who just left were the boys I told you about. They just told me how they appreciated the things Jim 'traded' them.
Now, at last, when Jim could not change his mind about color or size....they came to pay their debt.'
'We've never had a great deal of the wealth of this world,' she confided, 'but right now, Jim would consider himself the richest man in Idaho'.
With loving gentleness she lifted the lifeless fingers of her deceased husband. Resting underneath were three exquisitely shined red marbles.
The Moral:
We will not be remembered by our words, but by our kind deeds. Life is not measured by the breaths we take, but by the moments that take our breath.
Today I wish you a day of ordinary miracles ~ A fresh pot of coffee you didn't make yourself.
An unexpected phone call from an old friend.
Green stoplights on your way to work.
The fastest line at the grocery store.
A good old sing-along song on the radio.
Your keys found right where you left them.

Will you not laugh ?
Atleast smile...............
Several men are in the changing room of a golf club. A mobile phone on
a bench rings and a man engages the hands free speaker-function and
began to talk.
Everyone else in the room stops to listen.
MAN: "Hello"
WOMAN: "Darling, it's me. Are you at the club?"
MAN: "Yes"
WOMAN: "I am at the shopping centre and found this beautiful leather
coat. It's only £1,000. Is it OK if I buy it?"
MAN: "Sure,..go ahead if you like it that much."
WOMAN: "I also stopped by the Mercedes dealership and saw the new 2005
models. I saw one I really liked."
MAN: "How much?"
WOMAN: "£70,000"
MAN: "OK, but for that price I want it with all the options."
WOMAN: "Great! Oh, and one more thing ... The house I wanted last year
is back on the m ,000"
MAN: "Well, then go ahead and give them an offer of 900,000. They will
probably take it. If not, we can go the extra 50 thousand. It really
is a pretty good price."
WOMAN: "OK. I'll see you later! I love you so much!!"
MAN: "Bye! I love you, too."
The man hangs up. The other men in the changing room are staring at him
in astonishment, mouths agape.....
He smiles and asks:
"Anyone knows, who this phone belongs to?"

Beauty of Math
This was sent to me by one of the e mail friends ( Ramakrishna from Kulalampur). Really very very interesting. Big Thank you
THIS IS REALLY GREAT !!! However, don't cut it short. Be sure to follow the math logic to the very end. You'll be glad you did.

Now, take a look at this...
101%
From a strictly mathematical viewpoint:
What Equals 100%? What does it mean to give MORE than 100%?
Ever wonder about those people who say they are giving more than 100%?
We have all been in situations where someone wants you to GIVE OVER
100%.
How about ACHIEVING 101%?
What equals 100% in life?
Here's a little mathematical formula that might help answer these
questions:
If:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Is represented as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.
If:

And:

But:
A-T-T-I-T-U-D-E
1+20+20+9+20+21+4+5 = 100%
THEN, look how far the love of God will take you:
L-O-V-E-O-F-G-O-D
12+15+22+5+15+6+7+15+4 = 101%
Therefore, one can conclude with mathematical certainty that:
While Hard Work and Knowledge will get you close, and Attitude will
get you there, It's the Love of God that will put you over the top!
