First Impression: Organic Chemistry

Today I had my first lecture in organic chemistry and first meeting of the organic chemistry lab. The professor in the lecture seems like a pretty laid-back guy, he was wearing Asics running shoes with his khakis and blazer so he already gets a thumbs-up from me. I'm an Asics kind of guy. I like that their name is derived from the Latin expression "Anima sana in corpore sano" which means "A sound spirit in a sound body." The original quote from Juvenal was "Mens sana in corpore sano" which means "A sound mind in a sound body" but I guess ASICS sounds better than MSICS. High school Latin rears its ugly head again, sorry. Alea iacta est. Sorry, I think it's out of my system now! I'm sorry for the diversion, let's get back to organic.

Unlike the physics professor in our 50 minute class yesterday, the organic professor went over the syllabus in about 10 minutes, leaving most of the hour and fifteen minute lecture to actually lecture. He made a few introductory comments about organic.. it is the chemistry of carbon, and then went into depth in the language of organic and the myriad ways with which to depict the molecules we will study, some of which was review, like Lewis dot structures, but also dash line models (wedge represents the plane heading towards the viewer from the paper, dashed line represents plane heading away from the viewer). We started off with something simple, which was this:

Yes, it's good old methane, CH4. There are a bunch of ways to depict methane, including the 3D ball/stick model above, and we drew it a bunch of different ways, talked about nodal planes, lobes and phases, and how phases are depicted by + or - signs, which he admitted can be confusing, since they don't indicate a positive or negative charge.

Then we talked about line drawings like /\ could represent propane and it's assumed that each angle and each endpoint of the line represents a carbon atom and the hydrogens to fill its orbitals. We talked a LOT about atomic orbitals and molecular orbitals near the end of class. We also hit structural isomers very briefly near the end, talking about the line drawings, which seem to me like the easiest shorthand to use in organic chemistry. Then we talked about propane and specifically how this:

is not propane. You always have to assume the endpoints of lines are occupied by C's (carbons) he said, with the hydrogen necessary to fill out the rest of the orbitals present as well. So instead of the above being propane, this has a longest chain of 5 carbons, making it a pentane, with methyl groups at the 2,2 positions, 3,3 positions, and 4,4 positions (six methyl groups total) making it 2,2,3,3,4,4-hexamethylpentane. At least I'm not confused. Yet. Yay!

The lab was pretty straightfoward in that we did not do anything substantive. Our instructor introduced herself, she's originally from somewhere overseas (I know where she's from, I was paying attention, but forgive me for being intentionally vague), but has been in the US for over thirty years, and says when she gets excited she can be hard to understand so if that happens, we are to tell her to slow down. Next, we went around, everyone introducing themselves with their name, major, and something interesting about them. I just said I graduated years ago, I'm a post-bac. Not so interesting. In my lab section there are a few other pre-meds and a lot of sophomores and juniors. In addition the interestingness included a guy that has played the guitar for several years, a Redskins fan, an expert diaper changer and a girl that loves to dance. Gotta love those icebreakers!

We had check-in for our drawers, signed that everything was present even though no one really checked, student, lab instructor or even the director of the labs. I guess if something is missing at the end of the semester we're screwed. Oh well. The last thing we did after turning in our paperwork (sheet confirming we've already taken the organic chemistry I lecture somewhere or are currently enrolled in it, lab rules/safety sheet agreement, and combination personal info/emergency contact and medical Hx sheet), we watched a dated safety video that looked like it was produced in the mid-90s. I know at least a few people in the lab, one that I worked with in my genchem II lab, and he was a smart, dependable partner, which is always a plus. I don't get anxious about who I get paired up with, but it just sucks so hard when your lab partner does not know what they're doing or how to do the simplest of calculations (even in Excel!), which happened to me last year a few times. This one girl in question, one time she sent me a text wanting to compare my lab report to hers and WE HAD NOT WORKED TOGETHER! I hate being passive aggressive, but even so, I just ignored her text, thinking to myself, "Yes, why don't you 'compare' your nonexistent lab report to mine. That sounds great!"

First Impression: Physics

Physics seems interesting. I had my first class meeting for the lecture this morning, my recitation and lab meet on Wednesday, since I figured I would schedule them both on the same day and knock them out in one shot. The expectations don't seem unreasonable, there are 8 multi-part exams (multiple choice and problem-based where you have the problem and have to run through, show your work to the solutions). 2/8 of the exams will be dropped. That doesn't seem so bad but I swear my first time in undergrad it was rare for a professor to drop exam grades or even let you make it up. I still stand by my assertion that today's students are pretty coddled, or maybe professors are just more accommodating to students' needs now more than they were "back in the day."

The physics professors is a hoot. Yes, I said hoot. After we got through the administrivia of the class, and he broke out the powerpoint slides for chapter 1, the first slide said "What is physics?" at the top, and he said he didn't know. So he looked it up on Wikipedia (nice joke) before hitting enter and letting the next bit of the slide materialize. We didn't get that far since most of the first 50-minute session was spent going over the syllabus and expectations, along with a stern admonition not to be Twittering during class (tweeting?).

Sunday Long Run, August 30, 2009

Today I ran 16 miles in a little over 137 minutes, which... carry the 1... is a little over 8 min 30 second miles. The marathon itself is 26.2(ish) miles, and I've run two now. I am progressively getting faster, which is cool, and easily explainable. The first year I ran the Marine Corps Marathon, I was a little under-trained. I had done a fair amount of long runs, but never longer than 18 miles, but no speedwork and no tempo runs. I think my sheer stubbornness, despite the cramps, got me to the finish. In my experience, stubbornness can be a huge asset or a huge problem. On one hand, I think stubbornness can spring out of self-confidence and persistence, but on the other hand it can spring out of ignorance, i.e. you don't know what you're getting yourself into but keep on going anyway, despite conflicting evidence. I think the first year I ran it, it was more of the latter, and last year, it was the former. It's such a cliché, but experience really is the best teacher. Last year, I was a little better trained, and the stubbornness plus better (or smarter) training got me to the finish on a roughly similar course layout 25 minutes faster.

Realistically, I am looking at at least another 25 minute drop this year, but possibly DOUBLE that. Last year I ran a 4:56, but I am taking the training more seriously this year and also eating much much better. When I ate like crap the first two years, I felt pretty bad the days after my long runs, which was confusing at first. I wondered why I was sore when I wasn't shocking my system with much much longer runs than I had previously done. I had progressively and gradually increased my mileage, but my running economy had not improved much due to the lack of speedwork and tempo runs. During my long runs I had done a good job (I thought) of staying hydrated with water and getting some calories on-the-run, I tried pretzels for the salt at first. Have you ever tried to eat pretzels while you are running? Let me just say that I could easily understand that President Bush pretzel fiasco if he had been doing laps around the Oval Office. They were too dry. I switched to kid's fruit snacks - the theme ones like Scooby Doo, Spider-Man, Batman, etc., and eventually gels. Now I use jelly beans on long runs, and they're awesome.

The long runs I have done getting ready for this year's Marine Corps Marathon, which is on October 25th, have been faster than I have previously run and I feel fine the next day.

I'll let you know how I feel tomorrow!

Time Flies

If anyone is actually reading this, I apologize for the lack of updates! The fall semester is about to begin, I'm taking just two classes - Organic Chemistry and Physics, for a grand total of 9 hours. Everyone tells me Organic Chemistry is a weed out class, i.e. it's difficult, takes a lot of time... and so on. The physics I'm taking is an algebra-based physics, since I haven't had calculus in quite a while and that class seems more oriented towards the engineer-types.

You make the time in your life for whatever you think is important. I think it's important for me to do well in organic, so I will take the time and study and do practice problems for it so that I can keep up with it every day. I read ratings of my school's professors on RateMyProfessors, and from reading some of the ratings it's almost like you can tell what people don't want to take personal responsibility for their performance in a class and want to blame a professor that teaches a difficult subject, such as organic chemistry. Now I know that some professors make themselves more available to students, love to teach, and have an easier time connecting with students and making the subject matter interesting and relevant, while others would rather avoid students and be doing research. When the ratings vary so dramatically on certain professors though, it's almost comical to read the reviews and I also wonder just how big of a problem grade inflation poses, especially to me as a non-traditional student. It seems like today's college students want to earn all A's but they don't want to work for it.

Newsflash: "C" is average. If you are an average student, you'll get a C. B's and A's are reserved for good and excellent students.

The real world doesn't just hand you things because you think you deserve them. The sooner you learn that lesson, that you learn you have to work for what you want, work to accomplish your goals, the better off you will be in the future. Take it from me, I was not the world's greatest student my first trip through undergrad and I have the record to prove it. There aren't any shortcuts to success (aside from being well-connected or a trust-fund baby). Most of us that reach success or will reach it is through the sweat on our brow and our hard work towards what we find important. Keep your head down and let your work speak for you.

Two Years Later

Two years ago, on March 17, 2007, my mom died. She was diagnosed with breast cancer in 1999, and after a harsh round of chemotherapy, she was in remission for a year until 2001, when the cancer metastasized to her liver, lungs, and bones. She lived with a serious enough cancer that has a five-year survival rate of 5% for eight years, so she beat the odds just living into 2007. Knowing what I know now, about "the science" and the immune and lymphatic systems, the human body, anatomy, and physiology, granted that I have only had two semesters of it, does not make the loss any less significant.

The first year was pretty easy. I was mostly numb but realized there was a gaping hole in my life. If you knew my mom, she was the person that was always putting others before herself, finding any excuse to send a greeting card to someone, whether they were celebrating a birthday, an anniversary, some other happy occasion, or a get-better-soon card to aid someone in their convalescence from serious illness or surgery, etc. She was the person to take up the cause of people who needed help, including others with cancer, or survivors, and offer support and encouragement, or just share her story and try to comfort others. I wonder if the fact that she was a chronic worrier and probably stressed a lot about things she couldn't control contributed to her cancer and the fact it came back. I wonder if the surgeon didn't get a clear margin in the original biopsy or lumpectomy, didn't biopsy the right lymph nodes, or if he just didn't do the best possible job he could have done. I'm not stressed or worried about the past, while I am my mother's son and I have many of her attributes, I am definitely not a chronic worrier or stress out about things with which I can have no meaningful impact.

This second year without my mom has been more difficult. I have kept busy, but the numbness wore off, and I can't pinpoint the day, but it was as if a sudden realization washed over me that I would never get to talk to her again, to laugh with her, to share my tears and triumphs, to share my life with her. I could always be myself with my mom, completely open, vulnerable, and not worry about being judged. That isn't to say I'm not myself with other people, but you know as well as I do, that we're all a little more guarded when we're around people who aren't either A) close family or B) tight-knit friends. The shields come up when we're in mixed company, and it seems like it has to be that way, not because we are afraid of offending someone but because it's expected. I'm rambling. I was, and continue to be, a good son.

My dad remarried this past summer, to a wonderful woman. I am the youngest of three kids, with two older sisters, and we realized that it would be good for Dad to have a new woman in his life, and that if left to his own devices, his health would probably suffer, considering he is diabetic. My Dad is home now, and two years ago, he lost the love of his life. Dad, my sisters and I went to Mom's grave this evening to visit, along with one sister's husband and two young sons (3 years old and almost 4 months old). Dad admitted that he's thought a lot about Mom over the past year especially, and while he didn't say it outright, the sentiment was clearly there that he really misses her, even though they didn't have the perfect Ozzie and Harriet marriage. But honestly, who does?

The funny thing is my youngest nephew, the nearly-four-month-old, was laying in his car seat by Mom's grave marker, and I told him, "I'm sorry you didn't get to meet your Grandma, she would have loved you so much."

He smiled at me, and somewhere, I think Mom was smiling back.
