NASA Telescope Catches Thunderstorms Hurling Antimatter into Space
Scientists using NASA’s Fermi Gamma-ray Space Telescope have
detected beams of antimatter produced above thunderstorms on
Earth, a phenomenon never seen before.
Scientists think the antimatter particles were formed in a terrestrial
gamma-ray flash (TGF), a brief burst produced inside
thunderstorms and shown to be associated with lightning. It is estimated
that about 500 TGFs occur daily worldwide, but most go
undetected.
“These signals are the first direct evidence that thunderstorms
make antimatter particle beams,” said Michael Briggs, a member of
Fermi’s Gamma-ray Burst Monitor (GBM) team at the University
of Alabama in Huntsville. He presented the findings Jan. 10 at the
American Astronomical Society meeting in Seattle.
Fermi is designed to monitor gamma rays, the highest-energy
form of light. When antimatter striking Fermi collides with a particle
of normal matter, both particles immediately are annihilated
and transformed into gamma rays. The GBM has detected gamma
rays with energies of 511,000 electron volts, a signal indicating an
electron has met its antimatter counterpart, a positron.
Although Fermi’s GBM telescope is designed to observe high-
energy events in the universe, it is also providing valuable insights
into this strange earthly phenomenon. The telescope constantly
monitors the entire celestial sky above and the Earth below—and
130 TGFs have been identified since its launch in 2008.
The spacecraft was located immediately above a thunderstorm
for most of the observed events, but in four cases, storms were far
from Fermi. In addition, lightning-generated radio signals detected
by a global monitoring network indicated that the only lightning
at the time was hundreds or more miles away. During one TGF,
which occurred on Dec. 14, 2009, Fermi was located over Egypt.
But the active storm was in Zambia, some 2,800 miles to the south.
The distant storm was below Fermi’s horizon, so any gamma rays it
produced could not have been detected.
“Even though Fermi couldn’t see the storm, the spacecraft nevertheless
was magnetically connected to it,” said Joseph Dwyer at
the Florida Institute of Technology in Melbourne, Fla. “The TGF
produced high-speed electrons and positrons, which then rode up
Earth’s magnetic field to strike the spacecraft.”
The beam continued past Fermi, reached a location, known as a
mirror point, where its motion was reversed, and then hit the spacecraft
a second time just 23 milliseconds later. Each time, positrons
in the beam collided with electrons in the spacecraft. The particles
annihilated each other, emitting gamma rays detected by Fermi’s
instruments.
Scientists long have suspected that TGFs arise from the strong
electric fields near the tops of thunderstorms. Under the right conditions,
they say, the field becomes strong enough that it drives an
upward avalanche of electrons. Reaching speeds nearly as fast as
light, the high-energy electrons give off gamma rays when they’re
deflected by air molecules. Normally, these gamma rays are detected
as a TGF.
NASA’s Fermi Gamma-ray Space Telescope is an astrophysics
and particle physics partnership. It is managed by NASA’s Goddard
Space Flight Center in Greenbelt, Maryland. It was developed in
collaboration with the U.S. Department of Energy, with important
contributions from academic institutions and partners in France,
Germany, Italy, Japan, Sweden and the United States.

Ask jai……
Ask jai is a weekly column that will strive to honestly answer your job search questions relating
to job searching techniques, networking skills, resume writing and interviewing. The employment
situation is getting better, however, it is still a challenge finding were the jobs are located and how to
get pass the “gate-keepers”. As an Executive Recruiter I was privy to working directly with Corporate
Recruiters and understanding their process in selecting which candidates to interview and hire. I will
candidly answer your questions, possibly bluntly answering you questions, but I will be totally honest.
My objective is to help you achieve your employment goal.
A Change Is Coming
I am in my 60’s and after being self-employed for the last 20 years, I find that I must
go back to work for someone else. But, when I look online, my education and experience are outdated.
How do I write a resume that will showcase my strong points, excellent people skills, crisis management
and creativity? Sixtyish
Dear Sixtyish:
Key questions for you to answer right now are: Why do I want to work? Is it for need or added income? I
am bored? Want to give back to society what I have learned? Do I want to do something different or change
careers? Once you have answered any of these questions you can move onto the next step.
First, I would say you already have a lot of value that you can bring to the table for any company or organization.
You are obviously a successful business owner to have survived for over 20 years. So you will want to
showcase those skills and accomplishments as strong points in your resume.
You should use a functional resume format instead of a chronological formatted resume. The functional
resume is the best resume format for: career changers, people with over 15 years work experience with one
company or in the same field. There are at least three sections in the body of a functional resume: Summary,
Accomplishments and Experience, Skills, Education. The Summary section should state your key qualifications
and achievements. You should categorize the skills section with headings (i.e, Customer Service,
Strategic Marketing and Sales Planning, Finance and Budgets, etc.). List your accomplishment statements
under each Skill heading. Try to list those accomplishments that you are most proud which have happened
within the last five years. Accomplishment statements can include: business development, written and
verbal communications skills, management, motivational and organizational skills, creative thinking and
problem solving skills. Be sure to add quantitative and qualitative terms to your accomplishment statements.
List community, volunteer, associations and membership activities, classes or conferences that relate to the
position you are pursuing. Also include sections for computer, software and language skills. I would “fudge”
the dates and probably use the following 2000 – present in the Accomplishment and Experience section. Do
not list dates in the Education section. Include a focused and intriguing cover letter with your resume. The
cover letter should state why you are submitting your resume, the position you are seeking, and the reason
you no longer want to be self-employed. Emphasize that you will bring your entrepreneurial spirit and success-
driven value to their organization.
There are plenty of jobs out there for people over 60. You will have to really do your research and network
to find these positions. Here are a few websites to visit: seniorjobs.org, wisherworker.com, seniorjobbank.
com, workforce50.com, retirementjobs.com and aarp.org.
Everything you every wanted to know about how to find a job … but didn’t know who to ask. ASK jai. Send
your questions to: jai@resumeandcareerservices.com or visit the website at www.resumeandcareerservices.com.
If you haven’t already, perhaps now would
be a good time to mark February 19, 2011
on your calendar. It’s not any holiday that
I know of and I didn’t see anything listed
on the World Holiday Calendar (go ahead
– Bing it). I’m sure many nice people were
born on this day and it will mark special
anniversaries for countless others but that’s
not why we’re looking at this date right now.
This day is relevant for us techies because it
marks the day that the Internet will officially
run out of IP addresses, specifically the
32-bit IP addresses that most people are
acquainted with (eg, 123.45.67.89) and use
to connect to the Internet. It’s estimated
that 98 percent of these addresses (4.2
billion unique addresses) have already
been assigned for public and private use.
No one is expecting the Internet to come
crashing down on that day in particular but
it will make things a little more interesting
for those in the business of assigning IP
addresses.
Typically, IP addresses are assigned by
ISP’s and other telecom providers for
the purpose of granting access to the
telecommunications network known as
the Internet. The IP addressing scheme
is what allows devices connected to the
Internet to find and communicate with
each other and it does this by ensuring that
each device has its own unique address.
At its inception in the 1960’s and under
further development in the 70’s and 80’s, no
one could have imagined that the TCP\IP
addressing scheme would ever need more
than 4 billion addresses to accommodate
IP communication between unique devices
connected to the Internet.
When it began to become apparent that
this really would be the case one day,
development began on what is known as IP
version 6 or IPv6 for short. IPv6 uses 128-
bit addresses where IPv4 uses only 32-bit
addresses. Under IPv6, there are a total of
2128 (about 3.4•1038) addresses or 340,282,366,920,938,463,463,374,607,431,768,211,456 individual addresses (pronounced -
Three hundred and forty undecillion, two
hundred and eighty-two decillion, three
hundred and sixty-six nonillion, nine
hundred and twenty octillion, nine hundred
and thirty-eight septillion, four hundred
and sixty-three sextillion, four hundred
and sixty-three quintillion, three hundred
and seventy-four quadrillion, six hundred
and seven trillion, four hundred and thirty-
one billion, seven hundred and sixty-eight
million, two hundred and eleven thousand,
four hundred and fifty-six).
In other words, a ‘blankload” of addresses.
In order to facilitate the global move to the
new IP addressing standards makers of the
operating systems we use on our computers,
smartphones and other internet-enabled
devices have been implementing the
IPv6 standard in their software and on
their devices using a process called “Dual
Stacking”. This effectively allows both
versions of the IP standard to run on a
single device at the same time.
June 8th has been designated World IPv6
Day by ISOC, the international Internet
society. On this day Google, YouTube,
Facebook and Yahoo will all turn on their
IPv6 stacks for a full 24 hours to test user
IPv6 connectivity. Users will still be able
to connect via their default IPv4 addresses
but for the purposes of testing worldwide
IPv6 implementation these companies and
specially selected ISP’s will be measuring
the effect of running their sites and services
under the new protocol. You can test your
IPv6 connectivity now by going to http://
test-ipv6.com.
NED & PRINCE
My dear Auntie Evelyn turned 97 years old this past
November, and believe me when I say that you would
never know it if I hadn‘t told you. She is remarkably
healthy for her age, she has a “steel-trap” mind that
is as sharp as a tack and she still lives on her own!
Evelyn Swallow-Leake was born in 1913 in Worcester,
Massachusetts. She spent her years as a teen-ager
growing up during the Great Depression, which as we
all know was a rather difficult time in history. On the
other hand, it was a time that seems purely ethereal to
me, at least from the way my Aunt Evelyn describes
it. She really enjoys sharing her childhood memories,
and I truly enjoy hearing them. I try to write most
of what she shares with me down in my journal, and
I treasure many of her memories as if they were my
own.
In one of my recent conversations with Aunt Evelyn,
she recounted a very vivid memory of the many
times she accompanied her Uncle Carl Woods (my
great uncle) on a horse-drawn carriage, during his
lumber deliveries from one area of town to another.
Evelyn, who was about 12 years old at the time, would
wait by the road side after school had let out, knowing
that was when Uncle Carl was expected to pass by
with two horses towing a load. She would ride along
with him during the latter part of the day, until it was
time to take the horses back to the barn.
Even as a young child, Aunt Evelyn was an avid animal
lover who was fortunate enough to have had pets
of her own. Her face lights up every time she reflects
on her memory of showing her appreciation and affection
to the two work horses that pulled the lumber
truck Uncle Carl drove. She delights in remembering
the fact that she made sure each horse got a carrot
and a friendly pat on the nose before she was hoisted
up and assumed her position in the seat next to Carl,
then off they would go. Among the many specific details
that my aunt remembers about this experience,
most amazing to me is the fact that she recalled the
name of the company that Uncle Carl worked for at
the time. It was “Stone & Berg Lumber Company” of
Worcester, MA. Even more amazing is the fact that
Auntie remembered the names of the two horses
that pulled the loaded lumber cart. Their names were
“Ned” & “Prince”.
The day after Aunt Evelyn shared this fascinating
story with me, I decided to do a little research on Stone
& Berg Lumber Co., just to see if there was any history
available on the internet that I could connect to
Auntie‘s childhood memory. Well, I am happy to say
that my Google search rendered way more than I had
expected to find. First of all, I was so surprised to discover
that Stone & Berg Company is still in business!
I called the phone number provided on the website,
and I was directed to the current owner of the company
Jennie Berg. Jennie was very cordial and kind,
taking the time to listen to my story of how my Aunt
Evelyn had vivid memories of having been on several
Stone & Berg lumber delivery excursions back in the
mid 1920‘s. Needless to say, Jennie was as please as I
was with the fact that Auntie had such clear memories
about the early days of the Berg family’s business, including
such specific details as the names of the horses
that pulled the cart and delivered the lumber. Jennie
confirmed that Evelyn’s memories were perfectly consistent
with the history of their company, and amazingly
accurate down to the last detail. She was pleased
to know that my Auntie was able to remember and
share her story of having been there when the Berg
family business was in the hands of her grandfather,
so many years ago!
Soon after we talked on the phone, Jennie was
thoughtful enough to send me a package of Stone
& Berg Lumber Company memorabilia items, most
important of which was a photograph of the two
horses Auntie remembered, Ned and Prince, hitched
and harnessed to a fully loaded lumber cart parked in
front of the Stone & Berg building with a gentleman
standing beside. I forwarded the photograph to my
Auntie Evelyn as part of her Christmas package this
year, and after comparing the face of the man in the
Stone & Berg picture to a family photo taken around
the same time, we all agreed that the man standing
next to the hitched horses is indeed my great Uncle
Carl! I can’t begin to describe how happy it made me
to be able to bring my Auntie‘s story to life and “full
circle“! All it took was a listening ear, a little research
and a bit of random kindness from someone I have
never even met face to face. As you can well imagine,
my Aunt Evelyn and Jennie Berg were also very
pleased to have found a bit of their own family history
in a place and time where we might have least
expected it!

GREETINGS FROM THE HEART
New Years is behind us,
the lawn Santas have
been deflated for the
last time, and browning
Christmas trees line
the streets like rejected
orphans. I didn’t decorate
much this year.
Arranging greeting cards on a bookcase
was the extent of my festive efforts.
Since postage rates rise faster than
inflation, and the Internet has replaced
hand written letters with email, mail-
delivered cards have become more comforting
and nostalgic. Considering that
most of my mail is bills and
junk ads, the fact that someone
cared enough to put pen to paper
and spend 44 cents to send
me something is a real boost.
Also, if they’re anything like
me, and find card buying a
daunting task, it means even
more. Sometimes the right
card jumps from the rack into
my desperate hands, but most
of the time I stand staring at a
greeting card wall for a good
long time. This section is deceptive
because despite the
rows and rows of cards, 90% of
them are so recipient-specific
that they wouldn’t work for
you. For example, last summer
I just wanted to buy a Happy Graduation
card, but everything either said “For
Our Son/Daughter,” “For the Brightest
Niece/Nephew/Granddaughter/Grandson,”
“You’re Out of College Now!” or the
popular “From All of Us!” Finally I found
something that didn’t directly identify
my familial relationship or the graduate’s
level of education. The artwork left much
to be desired, but I felt fortunate to have
found anything at all!
Besides narrowing their audience, greeting
cards have become increasingly extravagant.
I’m thinking about the ones
with a small, computerized chip containing
more technology than existed in the
entire U.S. in 1950. These cards serenade
you once you open them, or play a prerecorded
message from Uncle Bernie congratulating
you that you’ve grown up from
the snot-nosed kid you used to be. I guess
if you’re going to pay upwards of $5, the
card better sing and dance for you. It’s
preferable to receive these in the mail instead
of at a birthday dinner, where other
restaurant patrons indiscreetly glance over
to see why Lesley Gore is belting out “It’s
my birthday and I’ll cry if I want to!”
I didn’t get any of these singing cards for
Christmas, which is fine by me, but now
that it’s time to put them
away, I’m faced once
again with a quandary
I periodically find myself
in –to toss or not to
toss, that is the question.
Beneath my sarcasm is a
sappy sentimental core.
So, disposing of cards can
be difficult. Even though
my mom sends me a card
for practically every major
and minor holiday,
not to mention periodic
notes of humor and encouragement
in between,
I can’t bear to part with
any of them! They cover
my desk, and postcards
have overtaken the fridge like ivy. I think
there might actually be duplicate postcards
of sea otters from Morro Bay.
My husband, on the other hand, is not of
such a sentimental nature. I remember
retrieving a postcard I sent him when we
were first dating from under a chest of
drawers. I laughed when he defensively
said that was his “special saving place”
for it. At least I only spent about $1 and
15 minutes of my time composing it. If I
ever get him a singing or dancing card, it
better not end up crooning for the dust
bunnies!
