School Bell’s A-Ringing

First day of the fall semester today.

I started it off with a visit to my research adviser, who has not one, but two different PhD thesis-level projects in mind for me. Gift horse, anyone? One of them involves an active NASA mission. One is related to (but not directly involved with) my Charon work. The first one comes with funding, wherein I would draw a stipend (plus, presumably, funding for conference travel). The second has no funding itself, although Dr. Summers said he could probably spring for a couple conferences.

Now I have to decide between an interesting project I get paid for and a (somewhat more interesting) project that I won’t necessarily get paid for. And since I could conceivably be working on whichever one I choose for the next 6-8 years (although presumably I would eventually find some funding for the latter project – except in the current anti-science administration, that’s pretty well impossible), I need to choose pretty carefully. However, it’s a good problem to have – rather too many projects than not enough (or an unhelpful research adviser).

After that meeting, and some chatting with various friends in the hallways, I headed to Senior Physics Lab. This promises to be quite an interesting class, with two half-hour lecture periods followed by 3-hour lab periods each week. Additionally, we can always get a key to the advanced physics lab to work independently whenever we wish. We each have to work solo (with a couple exceptions) on four different experiments throughout the semester. My first is a study of the Zeeman Effect on mercury vapor. On Wednesday, we have an oral pass/fail exam on our individual experiments which we must pass before we’re permitted to begin work, then it’s radiation safety education and quizzing next week and finally we can begin work.

Following lab I sat in on the first Introduction to Quantum Mechanics course. Although this course is packed to full (every seat taken), I have permission from the instructor to sit in on it unofficially. It is now a required course for all new Physics undergraduates. However, since I am running under an older catalog, it is only optional for me (I’m taking Astrophysics instead), but it is still a good idea to know the contents since a significant part of the physics GRE uses the knowledge. My main surprise in the class is the number of physics majors in there whom I swear I have never seen before. You’d think I would know (at least by sight) all the junior/senior level physics students by this point (since there are only a few dozen total physics undergraduates).

Tomorrow – three more classes (two audits, one for credit)!

Decision time approaches

As I enter my final semester as a physics undergraduate, there is a decision looming which I have put off for at least a year: What next?

My choices seem to be along the lines of:
- go back to slacking (the easy option)
- get a real job (the hardest option, in many ways)
- continue education

The final one comes with its own three options:
- aim to become a secondary education (6-12) physics teacher
- aim to become a university physics professor
- aim to become a researcher

Assuming that slacking and getting a real job are off the table for the moment, that leaves me with some complex choices to make, even if I stay at GMU for my continued education (UMCP is a far better physics campus, but I really dislike the idea of driving into MD each day for grad school).

GMU’s College of Education and Development (CEHD) offers a Masters of Education in a variety of subjects, including physics. For admission, one needs 3 letters of recommendation, a goals statement and successful Praxis I exam results. The Praxis seems to essentially be a GRE for the education side of things. The LoRs will be interesting to achieve – I am not sure what they are to recommend (my physics knowledge? My teaching ability? My personality and work ethic?). I’m sure I can find three profs who attest to my hard work at school and in classes. Not much teaching experience, however (that’s the whole point here!). The deadline for spring admission is November 1st. For next fall, it would be April 1st.

For either the professor or researching angle, I need a PhD. The work is essentially identical for either direction, only my concentration work would change. GMU’s sparkly-new Physics PhD program requires acceptable scores (whatever that means!) in both the general GRE (fairly easy) and the physics GRE (very not easy). There are only fall admissions for the graduate program, which leaves me with an April 15th deadline.

Given that I am unlikely to get all my testing done as well as other paperwork within 2 months, the April deadlines are more achievable. That means I can get my various paperwork collected throughout this semester and schedule my test-taking in late winter or early spring (so as not to worry about studying for it during classes).

Now I need to find someone who can usefully advise me as to paths and suggestions of how to approach them. I’ve already had one person suggest I find a high school physics teacher and ask to sit in on classes just to watch how things go. (Alas, he also suggested I do NOT choose a specialist school like TJHSST, the only place I actually might have access to a physics teacher, because I know his wife!)

And, of course, after all this, there is no indication one way or another that I would be any good at research or teaching in any capacity. I already know I don’t do well with teaching indifferent or uninterested students, which could be a challenge. On the other hand, research is undirected ultimately – a situation in which I also do not excel. That’s what I get for redefining my existence in my 40s.

Update: Just after I posted this, I received email from my favorite professor, which included in part this sentence:
“I have a potential Ph.D. thesis project if you are interested.” That may help narrow down my decision somewhat!

Another Semester Ends

The Spring 2008 semester is over, the grades are posted. I hear you breathlessly asking, “How did it go?”

Not too badly.

While I only registered for 6 credits this semester (3 lecture, 3 research), I actually sat through 9 credits of lecture. One extra class was by invitation from my research advisor. The other less invited, but he did not seem to mind (after all, I was a more consistent attendee than half the class). The full rundown then…

Senior Research Project – I talked a bunch about my research project here. I did not do any more flux work since my last post, but did continue working on vapor pressures of certain molecules (N2, CH4, CO and a variety of C2H* species) at very low (30-60K) temperatures. I originally was asked to turn in a sort of journal of my efforts for the grade. Before the semester was out, however, Dr. Summers let me know I had already earned an A (yay me!) for my work, but he still wanted me to turn in a paper which might be suitable for publishing on the low temperature vapor pressures. I finished writing that today and will submit it tomorrow for his review/editing.

Modern Physics – This was a very interesting class — a “survey” course (touching relatively lightly on a number of topics) covering special relativity, introductory quantum physics, Schrodinger’s wave functions, perturbation theory and similar fun. My one big regret is that we did not get to the last part of the book, which deals with subatomic particles (quarks and things). That was what I was looking most forward to! The instructor, Dr. Karen Sauer, is engaging and effective. I enjoyed her teaching and look forward to having her again for Senior Physics Lab next semester. The tests were not easy – GRE-based multiple choice plus course-based quantitative questions. No equations were given (just like in the GRE), so we had to memorize all the formulas as well as knowing how to use them. I studied harder for the final exam (5 full days) than I have for any other exam I have ever taken. Result (including her substantial curve to get the class average up to a B): A+ for the course.

Thermal Physics – I just sat in this class, not signing up for it (or talking to the instructor about it) because I was told it was critical for an astrophysics career (it probably is). However, it is not (currently) required to graduate – just one of a list of electives – and I chose to take a second semester of research for more fun. The instructor, Dr. Peter Becker, was not bad, if occasionally a goofball (humor is good, though). The book, however, was horrible. It was written in 1965 and completely unsuitable to today’s education environment – just page after page of text spamming your eyeballs without a gap. I could not take it and did not even crack the book after the first week or so. I still took very thorough notes throughout the semester in case it ever becomes important to me.

Atmospheric Physics – Another survey course! (Don’t we ever get to learn the real stuff?) This one was taught by Dr. Summers and I sat in it at his request. As expected, it was an enjoyable class full of great slides and interesting information about how the atmosphere works.

All in all, not a bad semester, although I started losing the urge to be in school somewhere in April (about par for me). One more semester of undergraduate courses – currently scheduled for Senior Physics Lab and Introduction to Astrophysics, although I may sit in one or more other classes as well again. We’ll see what happens!

Charon Research

Another semester nearly done and I have hardly posted at all. I’ll do a full summary once grades are in. For now, my classes are essentially done (one more on Monday night). Now I just have to finish writing up the journal/log for my research project, which I just realized I have not actually talked about before. Fairly briefly, then…

My last research project (with advisor Dr. Shobita Satyapal), done in Spring 2007, was based predominantly on Spitzer Space Telescope (and some older) infrared observations of a variety of galaxies. In that project I did a fairly rough, low sample comparison of various methods of determining star formation rate in galaxies (infrared, UV, visible light, etc.). Ultimately, I determined that infrared was the way to go for a variety of reasons. I am not sure how valid my results were (this was all new to me), but I got some interesting reactions from Shobita and one of her grad students, so that’s a plus.

This time around, I am working with Dr. Michael Summers, as I mentioned in an earlier post. He is working up a paper discussing the possibility of Charon having an atmosphere and the composition, density and lifespan of that atmosphere, if present. While the great bulk of the work (and all the theory) is his (and a collaborator’s), he has had me running some mathematical models using the IDL programming language. Technically-speaking, I am not really doing Charon research for much of it, because a lot of the models I am running (like determining equilibrium vapor pressures for a variety of gases at very low temperatures) has nothing to do with Charon specifically. Some of it, my earlier work (I actually started this work last May), used Charon parameters, however, so that qualifies. (Current direction of conclusions: yes, Charon most likely does have an atmosphere, which is picks up in part from Pluto’s evaporation while it is near enough to the sun.)

Since it is not really a full research project (I have no theory, no position, not much of anything), I am not sure how he will be grading it – hopefully just grading the quality of the programming output I did plus whatever journal I write up talking about my adventures making the models. He has used at least one of my output plots in a talk he gave to other atmospheric sciences, so I can’t be too far off in my models.

One thing I have learned about doing this research is that advisors are very hard to contact! Both of my advisors have been very out of the loop with my daily activities. In Shobita’s case, she delegated pretty much all of my handling to one of her post-docs. She was out of it enough that my conclusions were a surprise to her – she had not inquired as to my progress for many weeks prior to the final paper. I still have not gotten my graded paper back from her after almost a year of asking. In Mike’s case, he is a very busy man – two active NASA missions (New Horizons, AIM), one hopefully soon-to-be-approved mission (ARES) as well as papers he is working on and his class time. It is lucky for me I am sitting in on his atmospheric physics class this semester – it gives me 10 minutes each week to talk to him on our way to the parking lot after class! He apparently has a good number of grad students (like 6-8) working for him, although I only know two of them – neither of which gets much face time either, so at least I know it is not just me.

Faculty Candidate Interviews Redux

The final candidate (on Wednesday, not Monday OR Tuesday) spoke on the formation of terrestrial planets beyond our solar system. The topic was interesting, but the speaker needs a lot more practice. He was personable, but clearly nervous and lacking some polish. We did not feel drawn to him as a teacher, nor did he seem especially interested in teaching.

Our final recommendation – hire the first candidate if they want a teacher, hire the third one if they want a researcher, higher the last one if the first two say no and do not hire the second one under any circumstances (sorry about that). We will see how it all goes. The faculty committee makes its decision tomorrow and passes the recommendation up the chain.
