Serendipity and science...

As I get to know more folks who are well established in their research niches, I am struck by the trend that many of them recount influential serendipitous events in their academic/professional careers which guided them down a new path, perhaps to ultimately do lots of work in a field they never intended or imagined. Indeed this should not surprise me –– it seems commonplace that strong minds in sciences embrace interconnectedness and feedback between disciplines and tend to follow their interests such that they get their fingers into all kinds of stuff. And, I have no doubt that whatever drives such research diversification and/or the desire to descend new rabbit holes is different for everyone. However, I think that this trend likely reflects the heart of the scientific method. That is, science is an evolving dialogue that (ideally) does not have a specific trajectory and rewards scientists with adaptable attitudes.

"So WHAT?" you say... "You are rambling about the obvious."

Well, I'm fixated on this because I feel that many grad students –– myself included –– set out in their academic careers with their eye on some prize (everyone's proverbial carrot is a bit different)... and this may not be the most useful approach. That said, it may get you in and out of school faster and on to bigger and better things for yourself, and in that case it is wonderful for some folks. But for the scientists that inspire me, it is clear it has behooved them to be sensitive and malleable to the research climate and needs of the community. Mostly, such an attitude rewards them with more work and more resources (intellectual and financial). 

I arrived at Madison with a Masters from SJSU and no interest in EBSD, although I have kept a soft spot for microstructures and microspace for a quite while. I imagined a relatively straightforward path for myself, felt like I had a clear plan. I consider/ed myself primarily a field geologist... which may be just a cooler way of saying that I aspire to be a generalist, or maybe that I don't know enough to further specialize my skill set. 

I am a late-comer to geoscience (more about that another time), and I sometimes remark at the disconnect between my passion for geology and my overall lack of preparation for it. I often feel like I took a stab in the dark and struck gold. Yet, it is clear to me that among my fellow grad students (most of whom are rather brilliant at something or other), I am not even a strong "generalist" –– I have a lot to learn. 

And I am learning. I'm learning that I love EBSD –– that it augments my love for microstructure. And that may change. But it is exciting to be jazzed about something new –– it is suddenly all I want to do. That likely *will* change. But it is already opening my vision and opportunities, and I know that it is going to become a big part of what I do over the next few years.

Of course this is what school is for. And you probably find my blathering to be more predictable than remarkable. But now that I have written it down, I think what I am trying to say is that it it is powerful to remind ourselves that our roles in science are not predetermined. And that the community often benefits from the work of those who follow their intrigue and can flow.

MAC

It seems that the assignment of mass absorption coefficients (MAC) for elements involves some serious hocus-pocus and much assumption.

All of my officemates are out this week – conference in Italy; drilling on a ship in Japan.

Maybe I'll get more done this week, but I doubt it.

Filament burned out..

An update on my experience as an EBSD noob:

So... yesterday one of the postdocs was kind enough to let me sit in on some EBSP (Electron Backscatter Pattern) analysis he was conducting on some dunite from the Twin Sisters. He set it up to map orientation contrast (OC) of the olivine lattice planes across a 2x3 matrix with a 5um step-size. He started the maping at about 2:30pm and checked in on it at about 11pm only to find that the tungsten filament in the SEM burned out. A couple of the map "blocks" (in the matrix) completed prior to the burnout and are useful, but he will likely be back in to finish the mapping next week. I am going to join him for that, too.

Also, my academic advisor just mentioned trying to put together a short-course this sumer that Seth will lead... a crash-course type of thing on "all you ever needed to know about EBSD."

Every Tuesday...

... is SEM day!

Postgres regardless of progress...

Today I continued some work on a django interface for my Postgres database. It's actually quite easy, but I'm a complete noob... so only recently have I got it doing what I want. Basically, I now have a way to enter observations into forms that save all the info into its proper place in a relational database schema. I think it will be worthwhile in the future when I accumulate larger volumes of data (more mapping, sampling, thin sections, and EBSD data), and I look forward to the GIS integration with QGIS and GRASS. Anywhooo... Where's that paper I should be reading...?

EBSD

Welcome. This first post is just an excitement.
I signed up to attend the MAS workshop on EBSD at Carnegie Mellon in June.
I am excited about it.
A hefty portion of my (near-future) research will involve analyzing crystallographic axes of mantle materials to infer dominant slip-systems during deformation.
