Technical Writing Tips: Abbreviations and Acronyms

It’s common in science and engineering to use abbreviations and acronyms to shorten long words or terms. This comes in not only when communicating with others, but also in one’s internal communication. In our lab, we end up with tons and tons of files and directories full of simulation data. We usually give them cryptic names. “R0.1mmCV0.4x” or “CI250V5” or worse. Typing out long names all of the time is laborious, and we generally know what our own abbreviations mean. This comes into play with notes, too. I might write down CV instead of conduction velocity, LAD instead of left anterior descending coronary artery, or APD instead of action potential duration, or the more ambiguous “duration.” When thinking or writing about different sets of experimental parameters, I may refer to things with labels that are nonsensical without explanation. It’s an issue of practicality.

When communicating with outsiders, however, abbreviations can be a problem. They must be kept to a minimum in papers, abstracts, and posters. Even things that are talked about all the time in the field must be defined, as you can never assume that someone knows them. I’m working on a manuscript now, and I had to go back, count instances of abbreviations, decide which ones were worth using (used often) and which had to be spelled out (used infrequently). In retrospect — and here’s the writing tip — I should have written everything out in the manuscript to start with. It would have been easier to go back later with search-and-replace to abbreviate the most-used terms.

Science News for the End of November

Next, a post on things that definitely are not science.

A blur of a day

I awoke once more at around 05:00, without an alarm, but was a bit slow to get moving. I felt heavy, like I wasn’t meant to be up. No matter, I caught up on my RSS feeds, did my morning pushups and crunches, and remembered that I have today off from running because it’s the weekend. In reality, I should have run anyway since I skipped a few days this week, but I just wasn’t feeling up to it.

I’ve been setting up and running simulations all day. This takes a bit of time, because I’m running the simulations remotely on our cluster. I have to log in, set up the simulation, submit it, wait for it to finish, zip up the data files (they’re quite big but compress very well), copy them over, load them, play the sequence in the data viewer, and then discover yet again that something’s not quite right with the timing. I’m trying to initiate a spiral wave, and I fear that perhaps the model I’m using is too small. My excitable gap is too narrow. The problem is, this mesh must be relatively fine. Therefore, if I make it larger, my required computational power will increase quite a bit, slowing me down further. I’ve got another try running right now, and I think I’m getting close to the right timing. I’ll check it in the morning and find out.

In the gaps of time between simulation stuff I’ve been playing some Prince of Persia / Sands of Time, reading blogs, pruning my RSS feed list, making some phone calls, eating breakfast, brunch, lunch (with a margarita!), and dinner. Oh yes, skipping exercise and eating more. This is doing me a world of good.

The blog associated with HubMed was full of Mac-friendly goodness today, including links to a bunch of free games for Mac OS X. Most of them are available under the GNU General Public License (a.k.a GPL, free as in speech) and are originally Linux games. One of my favorites, which I played on Linux first, is Frozen Bubble. I have problems copying it to my applications folder for some reason, and have to play it off of the disk image. I was also reminded by the presence of Goban on that list that I should try picking up Go again. But not tonight. Maybe I’ll order a Go book from Amazon once their gift certificiate payment scheme is back up and running. By the way, I hope none of you have sustained any injuries during the post-Thanksgiving commercial feeding frenzy…

I know by this time you must be dying to see the stats for the day. Agonize no longer:

Sleep Water Exercise Coffee Green Tea Alcohol
8 h 2.5 L 0 min 2 cup(s) 4 cup(s) 1 drink(s)

If I’m going to get eight hours of sleep again, I should get on with my pre-sleep reading, and then crash. Ta ta for now.

Ramping back up

Being at home seems to sedate me. Not only do I not feel like doing work when I’m at my parents’ house, I don’t feel like doing much of anything else, either. I get way off schedule. I stay up too late and sleep in. And I was doing so well in St.Louis. Case in point? I prefer to go to bed at around 21:30. It’s now 23:41. I’m not tired. In my quest to begin drinking 4 cups of green tea per day, I neglected to consider that I should drink them in the morning, and not the afternoon / evening. Combine this with the fact that I haven’t been drinking much caffeine lately and… yeah. Not good.

Here’s a news item for you, courtesy of Slashdot. Evidence continues to mount that we are experiencing a bit of global warming, that nothing like this has occurred for thousands of years, during several cycles of the earth’s climate, and that the rise in greenhouse gasses and average temperatures almost exactly parallels the industrial revolution and the use of fossil fuels.

Hmm…

The greenhouse gas study is here, while the water level story is here. In science, when all of the evidence points to something, it’s generally considered to be the working theory. To say that this probably has nothing to do with human activity is like saying that because living things are complex someone had to design them — that is, it’s a cop-out that offers no counter-explanation, and no substantiated criticism.

In other news, here are the stats for today:

Sleep Water Exercise Coffee Green Tea Alcohol
8 h 2.4 L 18.88 min 1 cup(s) 4 cup(s) 0 drink(s)

There is some wine here, but it’s not open, and due to some sulfite allergies in the house, opening a bottle is akin to flooding the house with radon gas or something. I guess I’ll just have to have some next week when Amanda’s in town. I’m missing my drinks-with-dinner tradition. My exercise today was running. I felt too lethargic before running to air up the bike tires, get dressed in bike things, and go ride the bike. Also, I’m afraid of debris and crap on the roads, but they’re probably okay now. It’s been months.

I managed to squeeze out a little bit of work today, but it was not a top priority. Tomorrow, it should be. I have a lot to get done. Maybe I’ll shoot for four productive hours. I’m busy trying to induce a spiral wave in a sheet of tissue.
