Professional Service

Sorry about the slow posting this week!  I've been busy getting ready for a trip and Thanksgiving.  By themselves, they aren't that bad but I still need to get my regular work done so I've been trying to get ahead on that.  Hence, I haven't been on the blog as much as I'd like.

In my "About Me" section, I mention the 3 main parts of being an academic: research, teaching and service.  I've already talked about my research and teaching, so let me tell you a little about professional service.

Service covers basically any activity that enriches your profession but doesn't come in the form of teaching or performing research in whatever it is you do.  This could be sitting on a committee that helps ensure that the working environment is comfortable or you can serve the larger community through professional societies.  For physicists, the main professional society is the American Physical Society (APS) but I am also a member of the American Association of Physics Teachers (AAPT) and the American Astronomical Society (AAS).

This week, I am traveling to the APS Board and Council Meetings.  I sit on the APS Council as the representative of the Forum on Graduate Student Affairs (FGSA).  The Council is the legal decision making body of the APS and we vote on everything from general statements, to journal subscription rates.  Councilors are elected to the Board after 2 years (of a 4 year term) on the Council.  The Board does more behind the scenes discussions on matters before they are brought to the Council for a vote.  The Board meets 5 times a year and the Council twice (luckily for me, 2 of the Board Meetings happen the day before the Council meetings).  I will be sure to post later this week on what happens at these meetings.

Service is often seen as thankless work.  In many ways, it is.  That is one of the reasons I try to find ways to serve that I personally feel are fulfilling; that way even if no one notices the work I do, I still feel good about it.  Serving on the APS Board and Council is not only fulfilling, but I also feel deeply honored since I was elected by my peers to these posts.

The picture above shows Gay Stewart (University of Arkansas), Stefan Zollner (now of the New Mexico State University), and me at the LaserFest gala event that was held at the Smithsonian National Museum of American History on February 12th this year.  All of us are on the APS Council and were invited to represent the APS.  For me, this was a night when being nerdy was cool!  I got to mingle with several Nobel Prize winners.  This photo really doesn't show the extent that the Smithsonian went to for this gala.  You can read more about it and see great pictures here.  This is definitely a time when service was not thankless!

Louisiana Science Teachers' Association Meeting & X-Rays

I've been away on travel to the Louisiana Science Teachers' Association (LSTA) Meeting last week in Monroe, LA.  LIGO goes to present workshops and to advertise the Science Education Center (SEC) though a booth in the exhibit hall. 

Our booth in the exhibit hall featured a projection of the LIGO documentary "Einstein's Messengers", the Visible Vibrations exhibit from our exhibit hall, 'snacks' (inexpensive, miniature versions of exhibits that teachers can build and use in their classrooms - the Exploratorium has a nice catalog of 'snacks' here), brochures, and posters.  While it was tiring being on your feet all day interacting with the teachers, it was also extremely rewarding!  One of the most inspiring people I interacted with wasn't even a teacher.  One of the security staff was so fascinated by the Visible Vibrations exhibit, that he kept coming back and interacting with it for most of the day!  To see someone who isn't even our target audience (at least that day) exploring the physics involved was extraordinary.  On top of that, he made some of the most spectacular vibration patterns I've ever seen!

LIGO also presented two one-hour workshops.  The SEC director presented one on motors and I presented another one on the LaserFest kits that I based the LaserFest Teachers' Day on a few weeks ago (you can read more about it here).  I had enough kits for 30 attendees, but my workshop was at the end of the day on Friday and only had about 10 teachers attend.  While I was a little disappointed (my ego had me convinced that EVERYONE would want to come to MY workshop), it was also a blessing in two ways.  The first way is that I got to have a lot more one-on-one time with the teachers and they had much more time to ask deeper questions than they would have normally.  The second way is that there were extra kits to be had.  The teachers seemed quite happy when I told them they got to keep their kits and, when I asked if they would like to take another kit with them to share with other teachers at their school, their faces lit up.  Each and every one of those kits has now found a good home in a Louisiana classroom.

Today in History...

Today is the 115th anniversary of the X-ray (if you hadn't noticed from Google's Doodle for today)!  I can't count how many of these I've had in my life and how many times they have saved me from some medical trouble, everything from dental cavities to finding my kidney stone.

Speaking of which, the X-ray below is after I had a ureteral stent placed between my kidney and my bladder to bypass my kidney stone and allow my kidney to drain.  The stent is clearly visible and the kidney stone is the little shrapnel looking thing about a third of the way down the stent.  The top curl is in my kidney and the bottom is in my bladder.  I am so happy that both the stone and the stent are gone!

Busy Last Week: SESAPS Meeting and LaserFest Teachers' Day

Sorry for the lack of posts but I have been completely knackered after the events of last week:


SESAPS Meeting @ LSU

The American Physical Society (APS) has regional section meetings across the country and the end of last week saw the Southeast Section Meeting of the APS Meeting at LSU.  Since Initial LIGO was decommissioned a few days before, LIGO opened up a few of its vacuum chambers to the SESAPS attendees to show off the optics that were contained within.  This was indeed a rare opportunity as the chambers are only opened in between science runs AND only when there was crucial work to be done on specific components.  I work on site and I have only ever gotten to see inside a few of the chambers before.

Over 100 (and I believe I am being conservative) guests visited LIGO on Thursday afternoon and toured the Science Education Center, control room and LVEA (Laser Vacuum Equipment Area, otherwise known as the corner of the LIGO detector where all the neat stuff is).

Above is the inside of HAM6 (Horizontal Access Module - it has a table inside in instead of hanging the equipment from the top of the chamber) which is the output of the LIGO detector.  The taller piece of equipment on the table is the Output Mode Cleaner (OMC) which will help insure that the laser light has optimal intensity and phase to be used to detect gravitational waves (you can read a more detailed description of this kind of mode cleaner here).

This is what is inside of BSC1 (Beam Splitter Chamber - the kind of chamber where the equipment is hung from the top of the chamber).  This mirror (which looks like glass, but the front surface has a transparent light purple coating to make it reflective to infrared light which is what our laser is) is called ITMY (Intermediate Test Mass on the Y [south] arm).  (Test mass is our complicated way of saying mirror.)  This mirror sits just after the corner beam splitter of LIGO to intercept the light returning from the end mirror to bounce it back to the end mirror - this bouncing happens about 100 times before the light gets past the ITM to recombine with the light coming from the X arm and go to the output (which you just saw in the previous picture).

This is a picture of me and my husband, Derek (who is an engineer at LIGO).  The bright light you see shining from the left is the spot light that is illuminating ITMY.  This isn't the best picture, but I just had to have a picture of us in front of this mirror before they closed the chamber up - which is exactly what they did just after this picture was taken!


LaserFest Teachers' Day
 

I've been talking lately about the workshop I've been planning for middle/high school teachers of physical science and physics.  Since 2010 is the 50th anniversary of the invention of the laser, this year is also LaserFest.  To that end, the professional societies whose research have benefited from lasers all got together to sponsor LaserFest and to promote the educational outreach of lasers.  Since the SESAPS Meeting was taking place at LSU with physicists from all over the region, I decided it would be great to organize a LaserFest Teachers' Day to focus on the classroom kits the APS is distributing for free to teachers and to invite the meeting physicists to have lunch with the teachers and chat about what they do.

Organizing this event was quite the journey.  The first thing that needed to be done was to find the funding for the event (even if the kits are free from the APS, there are costs for food, recruiting and other miscellaneous supplies) which was supplied by the APS Forum on Education, the American Association of Physics Teachers (AAPT) and the Optical Society of America (OSA).  Then I needed to recruit teachers from the surrounding areas.  I was lucky here since I work with the LIGO Science Education Center and was able to advertise this event through their contact who also helped to spread the word.  Then there is making sure that the supplies arrive in time, contracting catering for the event, making sure that the teachers know when and where to be and insuring that you have all the incidental supplies that are needed (e.g. the kits contain everything a teacher would need except things they should already have like scissors and tape - but I needed to make sure that we had those for the workshop).  I know that none of these things sound like a lot, but this reminded me a lot of the last days before my wedding when all the details needed to fall into place at the same time.

The day started at 9 am with breakfast followed by a wonderful talk by Dr. Ken Schafer who introduced us to the basic concepts that make a laser work, their history and their applications.  We then proceeded to the first of the 4 activities in the 2009 PhysicsQuest kit (which included a laser pointer, and LED light, polarizers, glow-in-the-dark vinyl and colored light filters).  At noon, we broke for lunch and chatting with some of the physicists visiting for the SESAPS Meeting.  The rest of the afternoon saw us working through the remaining 3 activities and the day concluded at about 3 pm.

The picture above is some of the teachers hard at work doing the laser activity where we measured the width of our hair by measuring the diffraction pattern made by shining the laser on the hair.  That explains why the teacher on the left is giving herself a hair cut!

The APS has put together a useful page on arranging a Teachers' Day of your own - see it here.

I know that there are many people out there with poor opinions of our education system and the teachers within it, but I was truly inspired by these teachers who attended this workshop on their own time and without pay so that they can learn how to do these activities and take them back into their classrooms.  These teachers definitely went above and beyond to better themselves and their students!
