Anger Management Issues or An Instructional Moment?

Mr. Rideout flicks off his class...

 Oh no, Mr. Rideout - don't be so angry and unprofessional!

Seriously though, this is always a fun moment in the curriculum for me.  How else am I to demonstrate the right hand rule other than show the direction of force with my middle finger on a current heading to my left in a magnetic field pointed towards the class?

(For the non-STEM readers who are confused by this, find a friend who can explain the right-hand-rule to you (Also, sorry about your poor life decisions that led you to this situation where you can't appreciate some of the finer things in life!)).

A good example of how everything that happens in the classroom (well, in life actually) can only be understood in context...

Surreal Connections Across Time and Space

 What if you were still in contact with one of your earliest students?

AP Physics Dim Sum Run, Jan 2005

Swampscott Prom 2005

What if she came by for lunch 19 years later? (She was in my second batch of students ever, junior physics '03-'04)

What if she casually pulls out some notes she took from one of those classes from so long ago when someone tried to derail my lecture by asking for some "life lessons" and you replied by writing "Three Rules for Living a Happy Life" on the board?

What if she were now a teacher herself and was adroitly influencing the futures of another generation of students?

Well if all of those things were true, you would really be a lucky, fortunate person now wouldn't you?


Thanks, MG, for the early, steadfast, and life-long validation.  And thanks for turning out to be just as lovely an adult as you were a teenager!

An Epiphany on Epiphanies

from Merriam-Webster

Historically, I've always focused on the sudden-ness and insightful-ness aspects of 'having an epiphany'.  I mean I knew there was a seizure-like intensity about it when you have that profound 'aha' moment, but I think that I have been discounting the emotional aspect of it.  A near religious experience, if you will, that brings us closer to the origin of the word.

Here are two recent experiences I have had that I am now going to recategorize as epiphanies.  Both of these moments contained no new insight and hence no revelation, but, instead, were profoundly affecting and moving to me personally.  I experienced the insight in an emotive and profound way that was not accessible to me prior despite knowing all the facts. I am now thinking these emotional moment of intense feeling are more true to the word epiphany than previous times where I have felt my understanding settle in like puzzle pieces finally meshing together (that was more like aesthetic satisfaction I think).

A couple of years ago, I was looking at the sunrise and thinking about how I was actually on a rotating rock.  The Sun is just sitting there in space and I am being brought into view of the Sun by virtue of my riding along on the rotation of this rock which gives me a speed of several hundreds of miles per hour.  I've known this for most of my life, but in this moment, I felt it.  I got dizzy.  I got scared.  I had a glimpse of the scale of it all:  How big a rock the Earth is, how fast it is rotating and how far away the Sun is and yet it seemed to be speeding into view.  It was great.

A couple of day ago, on my way to work, I was appreciating the late spring that is unique in my experience to New England.  Spring doesn't just pop into existence here.  Winter lingers and there is a short war between spring and winter which spring eventually wins.  But the plants and animals each return to spring in their own time  and in their own way here - it is a series of transitions spread out over many weeks.  As I was appreciating this, I realized that the giant oak trees on my walk are the the most conservative in embracing the spring.  "Go ahead all you little plants and animals, I am biding my time and will send out some tender buds when I am good and confident it really is spring" I imagine them saying (Ent-like, of course).  When I glanced up to see their still naked branches silhouetted against the sky, I felt that I was at the bottom of an ocean of air.  A tiny-self aware being crawling on the floor of this immense ocean of nitrogen gas accompanied by all these other bottom dwellers.  The oaks alone were reaching upwards, striving to get away from the messiness and glory of life lining the bottom.  The ecosphere felt like a fragile thing to me then.  I felt part of it and it made me nervous that it could all be wiped away as easily as I took a dishrag to wipe the grim off the bottom of my coffee mug. 

I've known about the Gaia concept, the ecosystem, and the model of the atmosphere as being an ocean of gas for most of my life as well, but I really felt part of it  - humbled, scared, and proud all at the same time - in a way I had never experience before.

-------------------

To bring this post full circle, I think it not unreasonable to describe these moments of intense feelings, scale-defying and interconnected insights, as spiritual.  If so, isn't it interesting that my appreciation of science gives me spiritual insight?  I think Joseph Campbell would approve.

Dating Advice

 I was talking with my son this evening.  Somehow we segued to Noam Chomsky (that's the kind of thing I do I guess).  I regaled him of a tale from long ago.  When I was in grad school, there was a girl I wanted to date and so I asked her out to the movies.  She said sure even though it was a documentary.  

Turns out the documentary on Noam, Manufacturing Consent, was four hours long*, pretty dry and academic, and had an intermission.  My date suggested we leave during the intermission and I said "No way, this is fascinating!  MIT linguistic analyzing newspapers for subconscious bias, wow!" (completely serious - one might conclude from the evidence that I have always been a hard-core nerd and one might, indeed, be correct).  

Needless to say, there was no second date.

Seb asks me 'So, the advice is no four hour documentaries for a first date?"

I respond "No, it's a great sorting mechanism.  You need to find out about someone's lack of intellectual stamina right away!"

Apologies to PB for this post.  Also, I would like to dedicate this post to current student PS as he might enjoy (and possibly benefit) from it as well.

* I haven't told this story in years but I always say 'four hours' - I am disappointed by looking at the actual facts and finding only 167 minutes of the movie actually exist.

My Kind of March Madness Bracket

So, I know it's sports related and probably involves illicit, low-key gambling but it does seem that everyplace I've ever worked that there is some kind of March Madness bracketing going on.  I'm think it's college basketball related, but really I'm not too sure and I'm okay with that.

Imagine my pleasant surprise when I find out that the Perimeter Institute has instituted it's own March Madness Bracket:

The Battle of the Equations!  Yessir, my kind of people:



If you don't understand anything about this graphic - well, now you know how I feel every time a sport bracket comes up like this in March.

My money is on Maxwell's Equations for the win.  Sure Noether's got that deep fundamental appeal but Maxwell's got the universal charm that just shines light on everyone who encounter its beauty:





(got into deep space and let rho and J go to zero to really feel the beauty!)
