A Memorial Day Rock: Marble

Marble headstones at Arlington National Cemetery.

On Memorial Day I always remember the trips I've taken to Arlington National Cemetery in Arlington, VA. I still remember my first visit to the cemetery. I was seventeen and applying to the United States Naval Academy. I was down in Washington, DC for the Naval Academy's Summer Seminar, an intense week that gives Naval Academy applicants a taste of what it's like to be a Midshipman. After hours of early morning PT with Navy Seals, fitness tests, mini courses, and serious hazing, the visit to Arlington was relaxing in a way. However, seeing row upon row of white marble tombstones also made me wonder if I really wanted to attend the Naval Academy. Was I cut out for this? Was I going to be able to spend enough time doing the science I love so much? Most importantly, was I willing to sacrifice for my country? Make the ultimate sacrifice?

I was admitted-- early action-- to the Naval Academy, and I almost went there. Some days I regret my decision to attend Dartmouth rather than the Naval Academy, and I wonder how different my life would have been if  had become a Midshipman. I would be stronger, I know. Tougher. Probably less self-centered and selfish. I tell myself that I turned down the Naval Academy because I wasn't going to be able to do enough science as a Naval Officer, but I know that's not a complete explanation. I know that I also turned down the Naval Academy because I was afraid. Afraid of war, of being mistreated as a woman, of a minimum eight year commitment, of not being able to follow an order I disagreed with, of fighting in a war I disagreed with, of danger, of violence, of death.

I may have turned down the opportunity to serve my country in the Navy, but I grew up in a military family. Many of my loved ones have served and still serve their country. My grandfather and father were both Naval Officers, and my cousin currently serves in the Air Force. Actually, the Mervine Family has a long history of military service, dating back to Rear Admiral William Mervine. There's even a Fort Mervine out in California.

I was too afraid to serve and sacrifice for my country, but there are thousands upon thousands upon thousands of people who were not afraid. Or maybe they were afraid, but they served-- and sometimes died-- anyway. Whenever I am down in the Washington, DC area, I try to make a point of visiting Arlington National Cemetery. Standing amongst thousands of matching marble headstones, I feel sadness, pain, and pride for all those who served and died for the United States of America. I may not agree with all of the wars in which these soldiers fought and died, but I still feel grateful for and humbled by the countless soldiers who sacrificed their lives. To all those soldiers-- at Arlington and elsewhere-- thank you. We remember you.

Mystery Rock #2

Earlier this month I posted pictures of a mystery rock that were sent to me by one of my blog readers. On Friday I received an email from someone who had been directed to my blog from the Skeptics Guide to the Universe Forum. A friend of this person had found an interesting rock in a rock wall in El Paso, Texas and wanted to know if anyone could identify this rock. Below are some pictures of beautiful Mystery Rock #2:

Just a Typical Sunday Morning Conversation at WHOI

I had an interesting conversation with one of the security guards here at Woods Hole Oceanographic Institution (WHOI) just a few minutes ago. The conversation went something like this slightly stylized version:

**************

Security guard: Do you know where Mary* is? I noticed her car wasn't in the parking lot last night.

Me: Hmm... haven't seen her recently.

Security guard: I know she's been working in New York, so I sent her an email to make sure the car was okay. But I got one of those away messages.

Me: Oh yes! That's right. I forgot-- she's in Antarctica. The car is back this morning. I bet a friend just borrowed it.

Security guard: Antarctica?

Me: She probably has email there.  Don't worry. She'll probably reply soon.

Security guard: Antarctica? Isn't it winter there?

Me: Yes, but I think she's on a ship.

Security guard: On a ship in Antarctica in winter? Crazy scientists.

**************

Yes, we scientists are crazy. Speaking of which, I need to hurry on to my labwork. On Sunday morning. On a holiday weekend.

*Name changed to protect the identity of the crazy scientist.

Cape Peninsula in Pictures

Flowers at Cape Point, South Africa. April 2011.
I'm working late tonight running samples on the mass spectrometer. I've been in lab since 8:30am and really should go home, but I've decided it's better to stay up all night and run samples. Okay, maybe not all night. But probably until 2am or 3am. Actually, I'm happy about this long lab day. I spent a good four hours tuning the machine (which is a bit tempestuous, like many mass spectrometers) this morning, and the mass spectrometer is running beautifully right now. The machine is very stable, and the data quality is very high. So, rather than shut the machine down and return in the morning, I'm going to run as many samples as possible. As many of you know, I'm sure, mass spectrometers are usually happiest when they're constantly being run. So, I don't want to risk coming in tomorrow and losing all of the tuning and stability. Besides, I've been working on difficult chemistry for months, and the mass spectrometry is the final step. With every passing minute I am gathering more data that can be used in my thesis. Very exciting! I can sleep tomorrow.

Fortunately, now that the machine is tuned and running I only need to keep an eye on it and change something every few minutes. So, I have some time to post some more pictures of my recent trip to South Africa.

3 Quarks Daily Science Blogging Contest

My friend Christie Wilcox over at the blog Observations of a Nerd alerted me to the upcoming deadline for the third annual 3 Quarks Daily Science Blogging Contest.

Are you a science blog reader*? Or writer? Feel free to go over to the comments here and nominate a science blog post that you like for the 3 Quarks Contest. The deadline is May 31st.

Personally, I nominated Anne Jefferson's fantastic recent post Levees and the Illusion of Flood Control

[Warning: Shameless self-promotion ahead] I'm a fairly new science blogger and a scientist, not a professional writer. However, if you like any of my writings here on Georneys, please feel free to nominate them. Below I've listed a few blog posts of mine which I like. [End: Shameless self-promotion]

At the very least, please do go nominate some geology-themed posts! Geology needs to represent in these science blogging contests.

Geology Word of the Week: H is for Hotspot

Geology Word of the Week: L is for Lithosphere

A Geologist's Alphabet

Every week (except for the month when I interviewed my dad about Fukushima) since I started this blog back in November 2010 I've posted a "Geology Word of the Week." For some reason I decided it would be fun to cycle through the alphabet from A to Z, and I've now accomplished that, writing about words from Alluvium to Zanclean.

Perhaps the alphabet theme is cliche, but I'm having fun with it. So, I think I'll cycle through the alphabet at least one more time. You can expect another A word (Allochthonous? Alvin? Albite? You'll have to stay tuned!) next week.

Here's my first geologist's alphabet:

A is for Alluvium
B is for (Volcanic) Bomb
C is for Coprolite
D is for Dredge
E is for Eustasy
F is for Fabric
G is for Gondwana
H is for Hotspot
I is for Ichnite
J is for Jurassic
K is for Komatiite
L is for Lithosphere
M is for Magma
N is for Nabkha
O is for Ophiolite
P is for Peridot
Q is for Quaternary
R is for Rock
S is for Speleothem
T is for Travertine
U is for Uraninite
V is for Vesicle (and Vug)
W is for Wadi
X is for Xenolith
Y is for Yardang
Z is for Zanclean

Geology Word of the Week: Z is for Zanclean
