CatchUp Day 8 - 2019

Day 8's prompt was to write a poem that uses jargon.

Cheloniids
are quadrupeds
some are elephantine
others are flippers.
They lack teeth,
Instead having rhamphotheca.
The carapace is covered with keratin
Some are thought to demonstrate cloacal respiration
All are exothermic
And those that live in frigid lacustrine environments
Are known to brumate when temperatures drop.





So uh, any clue what that poem was about?

NaPoWriMo 2016 Day 17

Today's prompt was to find a specialized dictionary and use some words from it to write a poem. I wanted to use a Dictionary of Biology. I found one here. But it didn't seem very user friendly. So I wanted to use the glossary from my Mammalogy textbook. Despite the fact that I only had the last page of the glossary and my textbook is moldy (how did that happen?!?), I used it. I'm also planning to buy a new non-moldy Mammalogy textbook. I chose words randomly by closing my eyes and pointing a few times.

Zona pellucida
Turbinal bones
Vibrissae
Warren
Vomeronasal organ
Vicariance
Zygapophysis

Oh, boy, this is gonna be a doozy . . .

I am neither thick nor elastic like a zona pellucida
And my turbinal bones make me full of hot air
I have no vibrissae to help me feel
I am more suited to living alone, unlike communal rabbits who live in a warren
I'm not sure if my vomeronasal organ is functional
Perhaps I can use it to detect pheromones; I must use something for that purpose.
I often feel highly vicariant from those around me, though there is no natural barrier separating us.
At the end of the day my zygapophyses are constricted and it feels good to lay down for the night.
I feel weird and isolated from my species and my kingdom.


A combination of two of my favorite things: biology and poetry. Interesting, but definitely could be better.

Closet Christianity

Recently, there was a post on BuzzFeed where the author (an educated, straight, female) said that she felt that admitting that she was a Christian was like coming out of the closet, but she felt as though being a homosexual is more widely accepted than being a Christian.

In the comments that followed the post, people said all sorts of mean things. Someone called her homophobic, lots of people said she was entitled, not a minority, and had no idea what she was talking about.

Now, I don't know what it's like to be gay and to be afraid to let the people around you and the world in general know that you are gay. BUT I do know what it is like to be a Christian in the field of science.

There are scientists who are Christian. The two are NOT mutually exclusive. But throughout my education, I have been extremely aware of people who think that Christians are idiots.

I have been afraid of admitting to peers and professors that I am Christian because I am afraid that they will think that I am stupid (my intelligence is very important to me), I am afraid that I will be rejected, I am afraid that it will hurt relationships.

I don't actively try to hide the fact that I am a Christian, but I don't try to reveal it either.

I recently began my Master's of Science in Marine Biology at Texas A&M at Galveston. It is a science and engineering focused school. There are few religious organizations on campus. I don't know if I am actually in the minority on campus, but it feels like I am.

It stings when you are at work and you hear someone say, "Don't you just hate it when someone posts something religious on facebook? Doesn't that make you uncomfortable?" As though you aren't allowed to post your opinions or religious affiliation on social media. Or that it is socially forbidden. That it is taboo.

The United States of America was founded on religious freedom. It is in the 1st Amendment of the Bill of Rights. That shows just how important it is. But we have moved away from freedom of religion to freedom from religion.

Religious people are often looked down on. Christians are often looked down on.

I don't what to be thought less of for being a Christian anymore than a gay person wants to be thought less of for being gay. We are all people, regardless of our religious affiliation, sexual orientation, race, nationality, gender, sex, hair color... and we deserve to be treated as such.

Know one should have to hide who they are for fear of being mocked, rejected, ostracized, belittled, or hurt.

You don't have to like me, but would you mind at least trying to get to know me before you make that decision?

That's my two cents.

Applying to Grad School (or My Totally Weird Experience Taking the GRE)

So I'm applying to Graduate School! Which is exciting I guess.... I hope I get in, but I'm not sure if I'll go or not. I really want to but a) I'm sort of tired of school and b) I'm not sure how I'll pay for it (I'm applying for a non-thesis program which means there's little to no funding). But part of me really wants to go! So we'll see what happens, but first I have to get in! So first I want to give you a quick run-down of what the application entails. And then I'm going to tell you about the totally weird experience I had taking the GRE (but NO content of the exam, because that violates the rules of the test and can result in bad things, like my scores on the exam being cancelled. It's kinda like the AP tests and all that).

So for my application to grad school (which is pretty standard)  I had to submit:

  • The ApplyTexas application (again?!?!?) (if you aren't from Texas, this is the common application that ALL public schools in Texas have to accept and most private schools accept as well).
  • An application fee (which was $50)
  • Three letters of recommendation! This gave me a bit of pause, because I am introverted and shy, I don't tend to go to my professors' offices and get to know them. I easily thought of one professor (my go-to for letters of recommendation because I had him for two classes and I knew he knew me fairly well), remembered that one of my professors REALLY wanted all of us to go to graduate school (he told me he thought I would get accepted by the program when I asked him [through email of course - shy, remember] - that was so encouraging!), and thought of another professor who I knew knew who I was (the bar was kinda low here). I can not reiterate this enough: TALK TO YOUR PROFESSORS, it helps your grade and you never know when you'll need their letter of recommendation.
  • A statement of purpose - this is basically saying why you want to go to grad school, specificially their program, what you can gain from it, and what you have to offer. It's kind of like an elevator pitch. I feel like I could've done way better, but oh well.
  • A resume/CV
  • My GRE scores (it costs $150 to take this test by the way)
(For more info about what applying to grad school feels like see this buzzfeed article, it's pretty funny and accurate at the same time).



That brings us to My Totally Weird Experience Taking the GRE. So looks like this post might be a little long. Hopefully, you think this is funny/outlandish/entertaining or something.

So to begin with, I was frustrated because when I started looking into taking the GRE, I discovered that I could not take the GRE in San Marcos (where I go to school), but instead, I would have to take it in Austin or San Antonio. I don't have a car, so getting there would be difficult.  Plus it was $150! Believe me, I don't have that lying around. So I talked to my parents and they said that not only would they foot the bill, but my dad would drive me to and from the test (parents of the year, every year [my parents are awesome - this is not sarcastic]). So I sign up and my test is the following Wednesday which happens to be the week that school starts so no time to study for this super important test...oh well, I'll just do the best I can.

So the day of the test comes, dad picks me up from my apartment, we get lunch, and drive like an hour to the other side of San Antonio (I think, I really don't know most of San Antonio very well). And we go to a nearby Barnes and Nobles because we have about an hour til I'm supposed to be there. Then we head to a nearby shopping center where the Prometric Testing Center is "co-located" (pretty sure they made up that word) with a Sylvan Learning Center, but there are two doors so I'm not sure which one to go in. So I go in the Prometric one and walk down this really weird long hallway to another door which informs me that I need to turn off my phone and send my dad away. So he goes back to the car (where he'll wait for a little bit because I was slightly concerned they wouldn't let me test because the name on my driver's license doesn't 100% match the name I registered for the test with - but I couldn't figure out how to change it for the life of me).

The place is dead quiet. And there's like NO ONE there (but I hear voices coming from the back). It kinda looks like a doctor's office. So I go over to the reception desk that says check in here. And I stand there for a minute before a lady comes out and asks for my ID and asks if my phone is off and tells me I need to empty my pockets (which were empty, thankfully). She gives me forms on a clipboard and a key to a locker to put my stuff in but tells me to keep my ID with me at all times and that I'll need to sign the paper and copy the paragraph on the bottom and we can get started when I finish the form.

So I put my purse in the locker and go sit down to do the form. It's mostly just agreeing to rules. Then I accidentally check a box indicating I'm not a US citizen (which I am, whoops!), only I haven't realized it yet. So when I go to turn in the form (to a different girl) she's like "Do you have your papers or passport?" So I get super confused and say "No, just my driver's license." The girl looks at me like I'm crazy and is like, "Are you a US citizen?" I say I am. She tells me I checked a box saying I'm not...I quickly scratch that out and check the correct box which satisfies her.

She takes me back and has me stand on these two footprints. She has me pull out my pockets to show they're empty, then she has me rub my hands side to side in my back pockets to show those are empty too. She has me push up my sleeves as far as I can. She has me pull my pants up so that she can see that there's nothing on my ankles. Then she has me put my feet together and uses one of those paddle things they use at airports and what-not when you make a metal detector go off to make sure I don't have anything hidden on me, I guess. She also has me take off my glasses so that she can make sure there's nothing on the back of them (I have no idea what they were looking for - a disguised google glass, maybe? I'm way too poor for that and I have no connections so...).

Now I sit in front of a guy at a computer (which I notice shows all of the people at the computer stations in the testing room - um, creepy); he takes my driver's license and has me tell him the address I used to register for the test. And the email I used to sign up for the test, which makes me nervous because I have two and I don't remember which I signed up with and I'm wondering if I tell them the wrong one if they'll make me leave. I tell them my school email, which turns out to be correct (thank goodness). Then he takes a terrible picture of me with a webcam (which I later realize will be sent to the school with my score report, thanks guys). He explains a bunch of rules to me, which I'm fairly certain are the same ones I read and agreed to earlier. Then they have me sign in on a sheet they've made just for me, and of course I sign in the wrong spot (ooops! I'm nervous, guys, sorry).

Then the girl takes me into the room with my four sheets of scratch paper and two pencils that they provide and my ID and locker key. She tells me to stand with my back to the wall while she puts the stuff at my station. I sit down and a little over two hours later, I finish. I sit there at the computer for awhile, wondering if I'm allowed to get up and leave or if I have to raise my hand to let them know, because this is the one thing they didn't tell me. Finally, I decide I'll just stand up and see if ninjas jump on me or something (they don't). Sign out, get my purse out of the locker, put the key on the desk (as I was instructed). And I was SO glad to leave!

I wonder if they were supposed to take a blood sample, too?

Good luck if you ever have to take the GRE,

Sharon

Dating Guidelines

So you're entering into a relationship with someone! That's exciting! Maybe you've dated before but you want to proceed in this relationship in a different way.  But do you know how to go about it? I know I'm currently single, but I have dated in the past, I have read books, I have talked to people. What follows is a list of guidelines that I think would be useful in dating, and if/when I date/court in the future, I plan to follow them.


  1. Have Non-negotiables:
    • Non-negotiables are deal-breakers. Reasons you won't date someone. Define them, know them, and stick to them. There's no point in defining them if you are just going to throw them out the window as soon as you meet someone.
    • If you are a Christian, don't date non-Christians. I don't care if you prayed about it and you think God says it's okay. This is the test of all tests. This is the line of all lines. You can't have a Christ-centered relationship if the other person isn't Christian. You don't share the same values. If your faith is actually important to you, it will be a problem to be in a relationship with someone who isn't a Christian. This is Biblical. The Bible tells Christians to be set apart and not to marry non-Christians (this is two different verses). The Bible is the Word of God. If it so clearly tells us to specifically do something (or to not do something), we should probably listen.
    • My two biggest non-negotiables are that I won't date someone who isn't a Christian and I won't date someone who smokes. I have other preferences, yes, but if you don't pass those two tests, I won't date you.
  2. Set Boundaries
    • These boundaries should define what sorts of interactions are or are not unacceptable. For instance, it might be a bad idea to be alone in private together. You may not want to spend time together late at night.
  3. Make sure both of you are aware of the boundaries
    • Boundaries are easier to stick to if you are on the same page.
  4. Tell other people about your boundaries
    • Tell the people you spend the most time with or talk to the most, tell the people you live with, tell your parents. They will be able to help you stick to your boundaries.
    • Don't get mad when the people you have shared your boundaries with tell you that they think you aren't sticking to your boundaries.
  5. Listen to your friends and family
    • If they come to you with concerns about the relationship. Listen! Don't get mad, discount what they tell you, or make excuses. Often when we care about someone the chemicals which make us feel as though we are in love (oxytocin, serotonin, adrenaline, and some others) tend to make us perceive the world differently and can cause us to ignore our significant others' flaws which may be detrimental in the long run. What I'm saying is your family and friends may be aware of things that you are completely unaware of.
    • In fact, it would probably be a good idea to ask friends and family members what they think, especially people who know you well and who you trust.
  6. Don't have sex
    • When we have sex, our bodies produce the hormone vasopressin which, among other things, helps to develop a pair bond. It may cause a relationship that should've ended quickly to last awhile. And when you do break up, it will cause extreme pain when that pair bond is broken. It is in your best interests not to have sex.
  7. Hang out with your friends
    • Should the relationship not work out, it is important to still be close to your friends so that you can have support during this difficult time. And if the relationship is successful, you won't have to search out people to be in your wedding.
  8. Don't lose yourself in the relationship
    • It is okay to take interest in the things he is interested in, but he should take interest in the things that you are interested in.
    • It is also important to be able to do things separately, sometimes we just need some time apart.
    • Keep pursuing your interests throughout the relationship. You shouldn't have to give up an interest or a hobby to keep the relationship. He should respect that it is a part of who you are, he doesn't have to take up your hobbies, but he shouldn't prevent you from doing them.
    • This is another thing that will help should the relationship end, you won't have to figure out who you used to be before the relationship and it will help you to be able to do things that you enjoy.
    • In fact, my mother once recommended that I make a list of things that I enjoy doing and do them throughout the course of any relationship and I think this is a very good idea. 


Remember there's more to life than relationships, but if you are pursuing one or want to pursue one, be smart about it!

Also, you might want to check out my post on Courtship.

Happy Dating!

Evolution and Christianity - Through My Eyes

A little preface to this post:
This summer at the state park, I was talking to one of the park hosts and I mentioned that I had reconciled evolution and Christianity, although for me it was never too much of a problem. She said that I should write down how I reconciled the two, because it might help someone else. So I did. The result was about two pages, but it really is the result of my entire life in church and at least a year and a half of biology courses (I have taken even more since I reconciled my belief in God and evolution and they often provide additional support for my understanding). After I wrote this, I had planned to share it here, but I didn't plan to share it so soon.
Before my internship started, my parents and I stopped in Sonora, Tx at the little Methodist church there. The pastor talked to me beforehand and during the children's sermon, she asked if she could pray for me. One of the things she prayed  for was that God would help me to share my faith while at my internship, and I remember thinking "how am I going to share my faith as an intern at a state park out in the middle of West Texas?"
Well Saturday, I was speaking with the wife of one of the men who lives and works at the park and she mentioned that one of the campers had given her a Bible because they were talking about religion, and she is an athiest. She told me that she wants to believe because it seems to provide a lot of comfort to some people, but she just can't.
I've been thinking about how I can share this with her since then. My heart was moved and I really want to reach out to her. So this is my first step. I'm sharing it here, and then I am going to write her a letter and leave it in the Bible the camper gave her. It might be cowardly, but that is what I plan to do.

God conspires (I love that word) in strange ways.

If you are scientific and you are questioning Christianity in light of evolution, I hope this helps you. And if you are Christian and wondering how to speak to people who accept evolution as true, I hope this helps you as well. And for everyone, I hope you'll find this interesting and thought-provoking and I hope you'll learn something. 

As a biology student and a Christian, I realized early on that I needed to reconcile those two things. So I did some thinking and discussing with those around me. The evidence for evolution was strong. But the conviction in my heart that God IS real and that God created ME (and all of the beautiful things around me that made me want to study biology in the first place) was equally strong. The definition of evolution (change in allele frequencies in a population over time) was logical. But if the changes occurred to a great enough extreme, it would follow that a group of new, different, possibly reproductively isolated (the Biological-Species concept) individuals (yes, a species) could potentially arise. And this process could occur often enough to create the chain of organisms that scientists recognize. But, if this were the case, shouldn’t there be some sort of record of ALL of those intermediate forms (this would be Gradualism, of which, Darwin was a proponent)? Perhaps, the forms were indistinguishable from one another until the new species emerged? That explanation isn’t very satisfying; perhaps something else was going on?

Cue, Punctuated Equilibrium. If you don’t know, this is the idea that there were long periods of no change followed by shorter periods of rapid change. If the changes were rapid, then it would make sense that there would be few of the intermediate forms, and lots of the forms from the periods of stagnation. Makes sense to me.

Now let’s say we go all the way back to the very beginning of the chain of life on earth. We are taught in biology that life began with some sort of unicellular organism which could exist in an anaerobic atmosphere. Some sort of cyanobacteria came onto the scene, producing oxygen and maybe some bubbles of oxygen gas rose up from under water supplying oxygen to our atmosphere. Once there was oxygen in the atmosphere, further evolution could occur.

But we haven’t gone back far enough yet. What caused the planet to exist with an anaerobic atmosphere and that unicellular protist which eventually gave rise to all life? Depending on your school of thought, your answer may vary. Perhaps you’ll say the Big Bang. Or perhaps, you’ll say God. Let’s consider the former.

The Big Bang tells us that all matter was this huge ball of energy and one day it just exploded randomly forming the universe (which may be expanding or collapsing, go see a physicist for more, my understanding of the Big Bang is, admittedly, hazy) including our galaxy, including our solar system, including our planet.
So let’s go back even further. What caused the Big Bang?

…….

…….

……..

No, I’m serious, tell me, what caused the Big Bang?

Imagine a series of dominoes falling. The last domino has just fallen. What caused it to fall? The domino before it. And what caused that domino to fall? The domino before it…And eventually, what caused the very first domino to fall? Someone or something pushed the first domino which caused a chain reaction which ultimately caused the very last domino to fall. So what pushed the first domino? Let’s just say it was a finger.

The first domino is the Big Bang, by the way.

God is the finger.

In the beginning, God created the Heavens and the Earth.

On the third day, God created seed-bearing plants and fruited plants.

On the fifth day, God created fish and birds.

On the sixth day, God created the animals of the land.

Evolution says that plants were one of the first lineages to arise. Followed, eventually, by fish. Which in turn were followed by amphibians, then reptiles, then birds, and mammals. Sound familiar? It is essentially the same order.

But the Bible says that creation took a total of seven days, while evolution says these same events occurred over millions of years. There is this funny thing about the Bible, it wasn’t originally written in English. It was written in a variety of ancient languages, including Hebrew. In Hebrew the word "yom" which means “day” has at least three meanings: the first is the 12-hour period from sun up to sun down, the second is the 24 hour period from sun down to sun down, and the third is an indiscriminate amount of time (it could be a very, very long time). So maybe, the “day” mentioned in Genesis is really hundreds of thousands (or even millions) of years.

So maybe Genesis should actually say:

In the first thousands of years, God created the heavens and the earth.

In the third thousands of years, God created  seed-bearing plants and fruited plants.

And so on.

Now, I know some of you are challenging me. Maybe that’s all good and well to you, but you think you have the nail that will seal the case against me: what if we keep going back, if God caused the Big Bang, who or what caused God?


Dear friends, I remember as a little kid, I sat and asked myself that very question, I thought and I thought and I thought. Perhaps, God has a mom, I thought. But then, God’s mom would have a grandma, and she would have her own mother and so on and so forth. Friends, I gave myself a headache. Eventually, I accepted that God just was and is and ever shall be. I know from a scientific stand-point, that’s not very satisfying. But, from a religious stand-point, it is. I don’t have to understand God to believe in Him. I don’t have to know what chemical reaction has to occur to change cookie dough into cookies, I just know it works. And for me, God works. It might not be satisfying, it might not be testable. But I, you, we are too complex to have occurred through some long, convoluted process that occurred simply by chance. God was there, God made it happen. God is the finger that pushed the first domino.
