More from Jim Dao, NY Times about Afghanistan

Jim Dao of the NY Times is following a combat unit on their entire deployment to Afghanistan from pre-deployment through the getting back home.  Here's the latest installment.

There's some funny stuff about all the things that go wrong with a  new unit on its first mission.  It's front-page of the print edition today for those who read the old fashioned way.

Talking About Dante Again

Followers of this blog know I had a "Dead Poets Society" book group in Iraq beginning last July.  The first book we read was Inferno by Dante Aligheri, translated by Tony Esolen.  Yesterday I was talking to the editor of the magazine at my day job about science education and Dante came up.  Our magazine is Chemical Heritage.

We were talking about the construction and location of Hell--Inferno is a guided tour of Hell down to the center of the earth and out the other side.

By the way, for any of you who had a bad education or read Thomas Friedman, Dante wrote 200 years before Columbus sailed and knew the size of the earth within about 10% of its actual size--as did everyone in the Church at the time Columbus sailed.   All that Flat Earth stuff connected to Columbus is bullsh#t.

The whole conversation was fun, but the most interesting thing to me was the vote at the end of the reading Inferno.  The group decided by a small majority to reading Aeneid next, not Purgatorio, the second volume in Dante's trilogy of eternity.  The group came to admire Virgil and wanted to know why he was Dante's guide through Hell.  Several of the soldiers were also upset with Dante for sending Virgil back to Hell when he (Dante) went to Heaven.

Unfriending on Facebook

Unfriending is an ugly word.  But in the virtual world it is very easy to make a friend you know very little about.  Most of the friends I have on Facebook are people I know in real life.  By category most are

• Riding buddies
• Army buddies
• High school classmates
• College friends

But there are some people whom I have never actually met.  Some of them follow my blog, some were on online discussion groups I participated in.

Last week, I unfriended a guy I have never met in person, but we have traded opinions for a few years.  He is a very smart guy who fires back hard whenever he thinks he is right or the other person is wrong--which is mostly all the time in my experience.  His Facebook comments can go to hundreds of words.  Anyway, I never minded his dismissive comments because I asked for them by being equally dismissive of him.  But last week I posted something that got positive comments from two "live" friends and scorn from the other guy.  Rather than confine his scorn to me, he lit into my college friend and my former co-worker.  

At that point all the protective instincts in me said this is wrong.  I should not allow my facebook page to be a WWE event.  I also sent my former Facebook friend a message saying why I hit the unfriend button.

There are many things I like about the virtual world.  But if a man is on your turf and insults your friends, it is clear that the relationship is in serious trouble.  In the virtual world, physical presence cannot put a brake on bad manners.  

Back to Riding for the Team

Today was a small but important milestone on my road back to racing.  And I am not talking about contending for wins.  At its best, my ability to sprint is about equal to the acceleration of a fully loaded tanker truck going uphill. 

But bicycling really is a team sport and my place on the BiKyle/Mazur Coaching Main Line Cycling team is helping the riders who can climb/sprint to win races.  Today’s race for the 55+ riders was 20 laps of a one-mile serpentine loop at the Rodale Fitness Park in Trexlertown PA.  The twisting circle is wide, smooth and has a flat, straight run to the finish.  Perfect for sprinters.

Only 18 riders started our race and three of them were in the 65+ category.  Three members of my team, Dave Nesler, David Frankford and I, were on the start line.  Nesler is a good sprinter, but there were a few very good sprinters in the so Dave would need to go before a pack sprint and stay away to win the race. 

The race started off slow with a few attacks that raised the pace.  When the speed dropped below 23mph, someone would occasionally attack.  Above 23mph the pack stayed in a line and rode wheel of the guy out front.  Riding out front of a pack means working about 30% harder than everyone else.  The guy out front is giving up energy.  The sweet spot is to be in the middle of the pack, surrounded by other riders who block the wind.

With six laps to go, I rode from the back (where I was resting from the last attack) and asked Dave if he would be better off with the pack going faster or slower.  He said slower.  Less than a minute later, Barry Free took off at the front and I followed him.  Once I was on his wheel Barry sat up and the pack was on us in a few seconds.  Rather than drop back, I stayed on the front of the pack, keeping my average speed as close to 23mph as I could--fast enough that no one wanted to raise the pace.

About 1/4 of the way around the final lap, the pack went around me to the left.  I started to swing to the right to get out of the way, but Dave decided to attack down the right.  He yelled, I inched left and he took off.

His move didn't last the whole way around.  I did not see the end of the race, because as soon as the pack went around me, I rode at half speed for the rest of the final lap.

Dave didn't win, Chip Berezny sprinted to the take top prize.  But at least I am back enough to contribute to the team.   

Piss Bottles

In writing about daily life in Iraq, I neglected to write about Gatorade bottles.  Specifically, empty Gatorade bottles.  I never went anywhere without one.  I never had to use the one I kept in my backpack whenever I boarded a helicopter flight, but I always had one.

Neither Blackhawks nor Chinooks have latrines.  And as some of their crew like to say, "We can stay up for hours."  In any case, I made sure to hit the latrine before boarding every flight and had that bottle just in case the Blackhawk had to stay up longer than I could wait.

In all the convoy training we did at Fort Sill and in Kuwait, I had that same empty bottle just in case that convoy kept moving.

And I kept an empty bottle in my CHU, just in case. . .

My commander once announced that he only relieves himself three times a day.  Any more than that is a waste of time.  I agreed with him in principle, but in actual fact, I am 57 years old and that kind of schedule is a long way in my past.

Writing for the blog Periodic Tabloid: gravity and Pseudoscience

July 30, 2010 | Neil Gussman

Recently the lead article in the Science Times profiled a string theorist who claims gravity does not exist.  

Instead, physicist Erik Verlinde says “gravity is a consequence of the venerable laws of thermodynamics, which describe the behavior of heat and gases.” Verlinde is not denying the phenomenon nor expecting pigs to fly, he just wants to describe why gravity keeps us firmly on Earth.

Theories do have a history of falling out of favor. In the late 1600s, both Christiaan Huygens and Isaac Newton developed useful and mutually exclusive theories of how light travels. For Huygens, light was waves. For Newton, particles. Huygens got a big boost from Augustin-Jean Fresnel in the early 1800s when the French scientist described light as waves in the omnipresent ether.

Almost a century later, the ether theory was found to be false. And in the 20th century both the wave and particle theories of light turned out to be true at the same time.

As a history of science organization, CHF follows the fortunes of theories from their inception through their ascendance and acceptance, and on to their demise. We may one day see the demise of the theory of universal gravitation. Theories, as a rule, rise slowly and fitfully and fall like a rock tossed off a building—gravity accepted as true for now. In all science, minority positions like Verlinde’s are part of every discipline. But sometimes these minority positions leave science and go another way.

As such CHF also tracks the history of pseudoscience. For us, the rise of a theory that never gains scientific acceptance is as interesting as one that wins acceptance as a way of understanding material reality. For example, why did creation science evolve and thrive in the United States, just as this country became the world leader in science? In the middle of a country that boasts Caltech, MIT, Harvard, Stanford, Apple, Intel, and Genentech sits the Creation Museum near Louisville, Kentucky. Inside Cain and Abel play with pet dinosaurs and the speed of light is considered variable.

Scientific theories are some of the most ingenious products of the human mind when based in fact. But even when they are not, the history of science in all of its forms is fascinating.

Visiting Pittsburgh--Nigel's First Foster Family

Today we got up at 3:45 am to drive to Pittsburgh for a math conference where my wife is a presenter.  Our girls are working, traveling and otherwise occupied so only Nigel and Jacari came on the trip.  Annalisa had meetings from 10am till 230pm then she and the boys drove to Dormont, 9 miles south of Pittsburgh to visit Nigel's first foster family.  I rode there and got a chance to ride over Pittsburgh's Mount Washington, while they drove through the same mountain in the Liberty Tunnel.

The Sharbaugh family cared for Nigel for the first six weeks of his life--from when he left the hospital the day after he was born until six weeks later when we picked Nigel up and brought him to our home from their home.

The Sharbaughs cared for Nigel and 11 other newborn children in the first weeks of their lives, then turned them over to other families.  Wow!

I admire them very much in the same way I admire running backs who can smash though hulking linemen or hockey players who can speed skate and shoot a blazing slap shot all in one motion.  The Sharbaughs, the running back and the hockey player all can do something I can't do.

Imagine taking care of a newborn for weeks and weeks and then handing that little baby over to strangers--not once, but a dozen times.  I can't.  They are one amazing family.  I'm glad we had a chance to visit them and get reacquainted ten years after they cared for baby Nigel.

[In case you were wondering, we are Nigel's second foster family.  It was almost a year before all the paperwork was approved for the adoption.]
