COSMIC BURST OF RADIO WAVES
A strange phenomenon has been observed by
astronomers right as it was happening—a “fast radio
burst.” The eruption is described as an extremely
short, sharp flash of radio waves from an unknown
source in the universe.
Over the past few years, astronomers have
occasionally observed this new phenomenon—a brief
burst of radio waves lasting only a few milliseconds. It
was first found by chance in 2007, when astronomers
went through archival data from the Parkes Radio
Telescope in Eastern Australia. Since then, six more
such bursts have been discovered in the Parkes data,
and a seventh burst was found in data from the
Arecibo telescope in Puerto Rico.
A team of astronomers in Australia developed a
technique to search for these bursts in real time. The
technique worked, and now a group of researchers,
led by Emily Petroff, Swinburne University of
Technology in Melbourne, have succeeded in
observing the first “live” burst with the Parkes
telescope. One of the big unknowns of fast radio
bursts has been their distances. The nature of this
radio signal—the way it is ‘smeared out’ in frequency
from travelling through space—indicate that the
source of the new burst is as much as 5.5 billion light-
years away.
As soon as the burst was observed, a number of
other telescopes around the world were alerted—
both on the ground and in space—in order to make
follow-up observations in other wavelengths.
“Using the Swift space telescope, we can observe
light in the X-ray region, and we saw two X-ray
sources at that position,” explains Daniele Malesani,
astrophysicist at the Dark Cosmology Center, Niels
Bohr Institute, University of Copenhagen.
Then the two X-ray sources were observed using
the Nordic Optical Telescope at La Palma. “We
observed in visible light and we could see that there
were two quasars, that is to say, active black holes.
They had nothing to do with the radio wave bursts,
but just happen to be located in the same direction,”
explains astrophysicist Giorgos Leloudas, Dark
Cosmology Center, Niels Bohr Institute, University
of Copenhagen, and Weizmann Institute, Israel.
So now what? Even though they captured the
radio wave burst while it was happening and could
immediately make follow-up observations at other
wavelengths ranging from infrared light, visible
light, ultraviolet light and X-ray waves, they found
nothing. But did they discover anything?
“We found out what it wasn’t. The burst could have
hurled out as much energy in a few milliseconds as
the Sun does in an entire day. But the fact that we
did not see light in other wavelengths eliminates
a number of astronomical phenomena that are
associated with violent events—such as gamma-ray
bursts from exploding stars and supernovae, which
were otherwise candidates for the burst,” Malesani
points out.
But the burst left another clue. The Parkes
detection system captured the polarization of
the light. Polarization is the direction in which
electromagnetic waves oscillate, and they can be
linearly or circularly polarized. The signal from the
radio wave burst was more than 20 percent circularly
polarized, which suggests that there is a magnetic
field in the vicinity of the source.
“The theories are now that the radio wave burst
might be linked to a very compact type of object—
such as a neutron star or black hole—and the bursts
could be connected to collisions or ‘star quakes.’ Now
we know more about what we should be looking for,”
says Malesani.

BOYS AND THEIR TOYS
OUT TO PASTOR

It does seem that some guys can never get enough toys.
Like knives. Not that knives are toys – they’re not – but grown
men who are still children at heart want objects that are
intrinsically useful, valuable, which can still be pulled out to
impress a friend, or even a stranger.
I have long liked knives of all sorts. Even ancient cultures
had their great diversity of broken and chipped rocks which
were their knives. Those were used for money, to show tribal
affiliation, and undoubtedly, the various craftsmen would
compare and contrast two spear points, looking for nuances
of meaning in the two points.
I find a knife indispensable. I presume that it has always
been the most basic fundamental tool which distinguished
mankind from the so-called lower animals who had lesser
brain functions. And the idea that knives are beautiful,
wonderful, and an intrinsic part of human life seems to be
well accepted among the mainstream. My evidence: I saw a
knife show on television, and all they did for more than an
hour (before I turned it off) was to try to sell you a great deal
on a special knife, but you had to hurry and buy now before
the deal expired, or before they met their quota of “strictly
limited to the first one million buyers.” Of course, there were
no knives on that show that I would consider buying. Those
were cheap knives for the masses.
I prefer to pay more for quality, or to buy from the maker.
There’s something about knowing the person behind the
knife, the person who has spent his (or her) life mastering the
intricacies of knife-making and metallurgy who then goes on
to actually produce beautiful, functional pieces of art.
Perhaps our knives are our ultimate mnenomic device,
embodying all the things we did with it during last summer’s
survival march, or the whole history of the evolution of
that particular style of blade. There is much to talk about
if you’re a boy with your toy. You pull out your knife, and
a lot is evident immediately. Folder vs. sheath. Stainless vs.
carbon. Leatherman vs. Victorinox. Big vs. small. From the
obvious, many conversations emerge. If a folder, we look at
the handle. Bone, plastic, wood, some sort of polycarbonate.
Is one better than the other? Some folks think so. We open the
various blades, and feel how it feels in the hand. Does it “walk
and talk”? The walking – how well it opens without peeling
off a fingernail, and we snap it open to hear it “talk.” Watch
the boys as they compare their toys. This initial phase is like
the opening of a sacred ceremony, and there is usually little
talking, just observation and some “ahhs” and “wows.”
Yes, knives are the sacred objects of the boys who go to the
woods.

questions to me.
A PENNY FOR YOUR THOUGHTS
The Gracious Mistress of the Parsonage and I were going into a
store to do some shopping. Her idea, not mine. Halfway to the
door, I noticed a penny on the ground so, being who I am, I bent
over to pick up the penny. It is a habit I picked up the day I was
born.
“What are you doing?” My wife gasped, thinking something was wrong.
“I found a penny and I picked it up. Finder’s keepers, loser’s weepers.” And I threw a
smile in her direction.
She looked at me and said, “What in the world did you do that for?”
“You know what they say, a penny saved is a penny earned.”
“It’s just a penny. What in the world can you do with a penny?”
As I stuffed the penny in my pocket, I looked at her and said, “I can stuff this penny in
my pocket.” Then I gave her a sarcastic smile as wide as the Grand Canyon, but not quite
as deep.
She sadly shook her head as we went into the store together. I, one penny richer and
smiling all the way. Pennies usually have that effect on me.
I know a penny is not worth that much. I just cannot resist picking up a penny I find on
the ground. I guess it is that Pennsylvania Dutch attitude I was born with. I never saw a
penny I did not want to pick up.
I can remember many a time at a checkout counter I was one or two pennies short and
had to break a $20 bill. You know what it is like to break a $20 bill? So, I try to have a little
backlog of pennies for just such emergencies, hoping I will never need them.
Do not let this get around, but on my dresser in my bedroom is a jar full of pennies. I
found them here and there. One time I remember finding 17 pennies on the ground in one
spot. What a great day that was.
My wife is always kidding me about this and when I am in some kind of meditative
mood, or so I want her to think I am, she will direct this to me, “A penny for your thoughts!”
I only look at her and smile, the temptation is there because I can always use another penny
and how many thoughts are really worth a penny? Especially mine.
Then a strange thing happened. We were home watching the news when the story of the
day was somebody auctioned off a penny for 2 . million dollars. If you do not think that
got my attention! Just one penny brought all that money.
I know right here I would sell all of my pennies for half that amount. Anybody looking
for a bargain? After all, I am not really greedy.
I looked at my wife, smiled broadly, and said, “A penny for your thoughts!”
“Who,” she finally said in a disgusting sort of tone, “would pay 2 . million dollars for
one penny?”
“I don’t know,” I retorted, “but I know who would sell one for 2 . million dollars.”
She glanced towards the bedroom where my pennies were at I said, “Don’t even think
it.”
Then we both had a good laugh together.
As much as I appreciate pennies, I am not going to go crazy about their value. I know a
2 . million dollar penny is old and has quite a bit of history behind it, but it will be a long
afternoon in the shower when I’m going to believe it’s worth that much money. Who in the
world put such a value on a thing like that?
I remember my father taking me to auctions and it always amazed me how much
people would pay for some things. They get so excited in the bidding and trying to outbid
somebody else that oftentimes they would pay twice as much as the object was really worth.
I remember my father would always say after some outlandish bid, “I sure would’ve
loved to have sold that to that guy.” Then he would stare out into space a little bit thinking
about that whole idea. He always wanted to be the seller and not the buyer.
Then my wife hit me with a difficult question. “Is there something you would never sell
for 2 . million dollars?”
What a loaded question. I am not even sure what 2 . million dollars is worth! I have
never seen that much money in my whole life and probably never will. But some people
have put value on certain things and are willing to part with something if someone comes
up with the right price.
People put value on things that really are not that important. An old penny worth 2 .
million dollars cannot be used for anything practical. What can you buy with that penny?
What is that man going to use that 2 . million dollar penny for? Just look at it?
I think Solomon had the right idea when he wrote, “For wisdom is better than rubies;
and all the things that may be desired are not to be compared to it” (Proverbs 8:11).
Some things in life you cannot put a price on, it is a joy to discover those things and
sometimes those things are people.
