Statues and Dinosaurs



While at the Museum of Fine Art co-chaperoning the trip with my buddy E.D., I found myself thinking about dinosaurs.  You see, our docent was making a big deal about the recent discovery that all these plain, classic white statues from antiquity were actually painted back in the day.  The statues were colorful and had a different look and feel than the austere, pristine feeling we associate with the statues as they have weathered through time. 


Growing up, not only did we think all statues were an unadulterated white, but we also thought dinosaurs had thick, scaly, leather-like skin.  However, just as modern science has discovered the microscopic remnants of paint on the surface of statues, so has DNA analysis shown that dinosaurs are more related to birds than lizards.  So, their surfaces and look must be re-imagined as well in the 21st century.


Way to go, Science - always making me rethink my understanding of the universe!

A crescent moon by any other name...



My father-in-law recently taught me the Chinese phrases for first quarter and third quarter moons, they are :

  Down   Bow string  = third quarter


Up    Bow string  = first quarter


Now, why would westerners think of quarter moons being left to right or right to left while the Chinese think of them up to down or down to up?  Both kinds of moons occur during difference times of year, based on the relative orientation of where you are standing on Earth, where the moon is in the sky, and where the Sun is.

Describing the moon as a "bow" in this phase is better than "quarter" for sure though, right?  We call it quarter because of where it is in the 29 day cycle.

In either case, everyone in the southern hemisphere sees their right hand side lit when we see the left hand side.  'Cause they are upside down in the southern hemisphere! Crazy business this is, living on the surface of sphere!

Slacker or Loser?


The year: 1995

The place: Shadyside, Pittsburgh

The event:  My buddy Borris' birthday

 Twenty-five and life was good.  I had passed my qualifying exams thus ensuring a smooth passage from being a Master's student to being an actual PhD student.  I was sharing a house with 3 other physics grad students and we had all just finished our slog through some 18 years of schooling and pretty major exams to finally arrive at the goal: ground breaking, original research.   After a few years of finding my feet in Pittsburgh and getting a new group of friends, I felt I had finally come to a comfortable, happy place in life.  I was in great shape, having lots of fun – crewing early in the morning, swimming in the afternoons, dancing in the evenings.  On top of the world as they say!

Borris was a little older – turning the big 3-0 today.  I was excited – this was a big birthday and I was looking forward to having a great evening of hopping a few bars, getting something to eat and hanging with friends.   Borris and I shared an interest in the intersection of computing, neuroscience, and physics. Walking my way to the bar where we were to meet, I thought about just how free I had become now that exams and coursework were over.  It was intimidating and yet liberating at the same time to pursue my own research and to be free of pre-set curricula.  What was I going to do with the rest of my life?  So many possibilities and so many directions to go in while still sheltered from the "real" world.

I entered the bar and my mood momentarily brightened even further – Borris has picked a sweet spot.  Some cool music playing at just the right volume; you could have a private conversation without yelling. Beautiful people scattered about.  I saw my buddy at the bar and headed over, motioning to the barkeep to hook me up with one of whatever Bo was having.

Instead of finding my friend upbeat and excited, I found him a bit sluggish and morose.  He'd been at the bar a bit longer than I had anticipated and greeted me with a mere nod.  I said "Happy Birthday, buddy!" and he just grunted "What's happy about it?". 

"What's wrong?"

"Ken, a slacker at 29 is a loser at 30."

Suddenly my lightness was replaced with heaviness and my mood went into a tailspin. I felt like a window in time opened up, showing me myself 5 years later sitting right where he was sitting, thinking just what he was thinking.  What was I doing?  Why was I still in school?  What was I going to do with that hard-earned PhD? 8 months later I had quit grad school and entered the "real" world.

To this day, I remember that little spin my world did at that moment.  Freedom turning into confinement.  Empowerment morphing into disillusionment.  Today, I think of that moment as an inflection point in my life.
Today, Borris is a successful practicing neuroscientist living in Paris and I, well, I have re-invented myself five times since that day (Winemaking in France, Architecture in New York, Engineering in Houston, Importing in Atlanta, Teaching in Massachusetts) and have no regrets.

Coming up on Thanksgiving and my thoughts turn to...

... Corsica of course!

http://riddicisms.blogspot.com/2009/11/thanksgiving-in-corsica.html

Are the events of that day so seared into my brain that it seems like yesterday or was it the act of writing down the story and reliving it every time I read it that makes me think I remember it like yesterday?

Hey You Guys!

I have always felt that the word "guys" is gender neutral despite having been told otherwise by many different people from many different walks of life (I just read an article recently about how a new teacher was put down by a veteran for his over use of "guys" when talking to his class (containing both guys and gals presumably).  Somehow I just can't shake my own usage of "guys" to mean both genders.  However, just recently, I've had a couple of revelation about the word "guys":

1)  My favorite show as a kid was PBS's "The Electric Company" (Morgan Freeman's original role!).  I only recently recalled the show's opener: "hey you guys!" I knew even back then that the show was shouting out to girl fans as well as boy fans!




2)  Guy Fawkes Night.  Ever hear of that one?  I hadn't - but when someone mentioned participating in one this November 5, I googled it to find out what was behind the mask.  Turns out this "Guy" is the origin of the word 'guy'.  We call guys 'guys' because this Guy Fawkes is so famous.  He went from real person to effigies which were made and sold to be burned on Nov 5. to being synonymous with raggedy persons of ill repute to being a general non pejorative term for men to (and I quote webster's online) "used in plural to refer to the members of a group regardless of sex"

Now that is an evolution in usage!  I think I won't beat myself up too much over calling a group of people "guys" any more.  All language is contextual, right, guys?

Brunch Coordinates

A couple of friends with kids were visiting for brunch.  Explaining how their 5 year old was trying to define 'bear', they said he did it this way:
"You know a Polar Bear?  It's like that except brown not white.  Also, it's not polar, just regular."
Being comfortably in the presence of fellow nerds, I chime in: "Ah, a Cartesian Bear then?"

No groans and no confusion, just some chuckles and nods of approval.

Before I feel too witty, I googled an image for this post with "cartesian bear" and apparently this is a common thought.

Aww shucks...

Making Jokes

So, my usual m.o. in class is to teach for a couple of seconds then make a bad joke, laugh at it myself, point out to the class how funny I am, and then berate them for not appreciating me enough.  Something along the lines of:

"When Newton wrote Principia, no one was forcing him to accelerate mankind's understanding of science." (slight pause) "Get it?  See what I did there?  Forcing?  Accelerate?  I'm funny." (serious students looking perturbed at their learning being interrupted, non serious students annoyed that I might actually think that was funny, and politically savvy students fake laughing).  "Oh - tough audience today."  (Sigh)

So, imagine my surprise when today I inadvertently made a funny while talking about circular motion (the need for a tangential velocity coupled with a centripetal force).  After some off topic remarks by some of the clowns* in the class, I try to bring us back to the physics with a "Usually, I like it when we go off on a tangent, but this is a bit much..."  Then I pause in confusion as they are all groaning and laughing at me.  Then I realize what I had done and promptly said "I gotta blog this."

Am I training them or are they training me?
