Beating Rachel to the punch =)





Rachel wanted pictures on her blog of our living room before we moved to the new apartment. But this week end our place has been covered with boxes. So I made the living room look pretty and posted these pictures. If you notice around the edges of the pictures there are what appear to be Tupperware containers and boxes and things. But that's just your imagination. Our place always looks pretty. hehehe

Summer Employment

This evening was Rachel and my eleven month anniversary. We celebrated by going out for ice cream and then walking along the levy. I can't believe it has almost been a year. It's gone by quick and at the same time not so quick. =) I mean it was not too long ago that Rachel and I met for the first time, and yet I can't hardly remember what life was like with out her.

I have been enjoying the work I am doing this summer. Instead of having one full time job I have had a couple part time jobs. First off I have an internship through the university. I am working for CAMD which stands for Center for Advanced Micro-structures and Devices. Basically in simple terms CAMD is a great big X-ray. The internship is for “pure” math majors to work in the “applied” sciences. It is really neat because most of the time what I am doing at LSU is sitting in front of a black board filling it up with equations and such. The question “What is this used for?” is the last thing on my mind.

The specific branch of CAMD I am working for is the tomography department. What they do is they take 2 dimensional shots of some object and try to reconstruct what it looks like inside 3 dimensionally. They have showed us 3d models of the way a cat claw grows. The first time I was at CAMD they were checking out the porousness of sandstone for the off shore drilling that Exxon is doing in the gulf.


So what am I working on? Plastics! So you are reading this on my blog. The monitor you are looking at is mostly plastic. But chemically that plastic is very similar to gasoline. That is why the plastics are made with flame retardants. What we are working on is several shot of plastic that is being melted. What were are studying is the movement of the plastic as it melts.

The pictures below are 3d images of an air bubble floating inside the plastic. As the plastic is heated the bubble is moving. The flakes all around the bubble are the flame retardant. We could try to follow the movement of the retardant, but it’s easier to follow the bubbles since they are bigger. There are multiple bubbles in the plastic but the pictures below have just focused on a single bubble over six time frames. So the bubble is expanding and moving upward as the plastic is being heated.

In addition to the work at CAMD I have also been doing work through a temp agency. I have been driving around the surrounding areas working for COX which is a phone and cable company. My work has entailed taking a disposable camera and taking picture of what are known as VRADS. What is a VRAD? It is a video ready access device according to Wikipedia. It is basically a big box connecting to underground cables. Cox has the latitude and longitude of where these VRADs are located. My job was to look up these locations on google maps then drive around to take pictures of them when I find them.

What’s funny about this job is how it makes you look at the world differently. For example did you know that next to every four way traffic light and every railroad track that has lights of some sort there will be a big box nearby. Look for them, they will be there. The reason I noticed this is by looking for VRADs and realizing those were not them. The specific thing that distinguishes VRAD will be the Att&T logo or the old bell logo on older equipment. The older smaller boxes are not actually VRADs, but they often are up graded to become VRADs.

The other part of my work this summer has been studying. (no pictures regarding this, but it would mostly be blackboards filled with equations) I have a Phd adviser and I am scheduled to have my oral exam in the Fall. I don’t know yet how much longer I will be working on the Phd, but things are moving forward.

I know I don’t post very often. I’d like to post more. But I hope that my small fan base enjoys it when I do post.

Pictures from my jobs





ABOVE: These two shots are picture like those I would have taken while working for COX. The first big box with the meter next to it is a VRAD. The second smaller cabinet is not a VRAD. It is an older cable box that could be ugraded to a VRAD.

BELOW: This is the type of 3d modeling I am doing with CAMD. The first shot shows a bubble in red and then the SAME bubble 10 minutes later in purple. So in that time span the heating of the plastic has cause it to expand and move to the right (as we are viewing it). Each of other rainbow colored bubbles is this same bubble at two minute time intervals between the starting point in red and the ending point in purple. The biggest change in both size and movement is from two minutes in orange to four minutes in yellow.

Bea, Pearl, and Barb

I first met Bea Hoekstra in the fall of 1997. It was my first Sunday at Collegiate Presbyterian Church on the west side of the Iowa State campus. When I told Bea I was a freshman she said, “I always love hearing that. It means you will be here for a long time.” Bea and her husband Jim were kind of like spiritual parents to us young college students. Their door was always open. I think about coming to their home during some of my dark lonely times my Sophomore year. After college I came to visit Jim and Bea. It was right after I had left my job teaching in inner city Chicago. It felt ironic to me that although Bea had been battling colon cancer for many months, she was the one strengthening and encouraging me. In January of 2006 I came back to Ames again to see Jim and Bea. I was applying to 6 different PhD programs, and I was picking up my college transcripts from Iowa State. I remember hearing Bea pray for me at lunch, “Lord give Dave 5 closed doors and one open door”. Over the next 3 months I received three rejection letters and one acceptance letter (to LSU) the other two schools never got back to me. The prayers of the righteous are powerful. That lunch was on a Wednesday. The next day, Thursday, Bea went in to the hospital for chemotherapy.

The last time I saw Bea was 3 months later over memorial day weekend. A friend from college, James, went with me to see her. Her body was frail, but her spirit was so strong. We were sitting in the hospital lounge when another women joined us. She was asking about the puzzle on the table. In the discussion I mentioned my family had a Narnia puzzle we would solve during the holidays. “Have you read those books?” Bea asked the woman, “The Lion in the stories represents Jesus." How sweet it was to hear that name on those lips.

That next October Bea passed away. It just happened to be the weekend I was back in Iowa for fall break. Being a northerner living in the south I was missing the changing of the trees. Bea's funeral was on a Sunday afternoon. It was a bright, crisp day and the red orange and yellow leave were falling silently across the cemetery. It was so sad to see her go, but it was abundantly clear the joy that Bea had now come home.

My Grandmother Esther was one year younger than her sister Pearl. There were six siblings total in their family spanning over 2 decades: Lowell, Pearl, Esther, Rosalie, Joe and Jean. My Great Aunt Pearl never married. She went straight to Hougten College from high school and went straight to Haiti from Hougten where she was a missionary for the remainder of her life. She would spend three and a half years in Haiti and 6 months back in the States. My mom talked about how exciting that forth year would be when Aunt Pearl would come home to see everyone. I saw a picture this summer of my Mom when she was about five with Aunt Pearl, Aunt Rosalie and Grandma.

One of these years that my Aunt Pearl came home was in 1974 when my mom was in college. She brought home this long haired kid named Howard Chapman, my dad. Grandma didn't know what to think of him. But my dad's parents had also been missionaries that came out of Houghten. In fact a neat little story about this was a trip Rachel and I took this summer. I wanted Rachel to meet my Aunt Rosalie who is now in her 90's. Rosalie gave me Aunt Pearl's old college year book to give to my mom. In the year book was a note from Pauline Chapman who was a Freshman when Aunt Pearl was a Senior. That would have been my Dad's aunt, years before my Grandparents had even met. So when my Aunt Pearl met my dad they had lots of stories to swap. Aunt Pearl told my Grandma, “He would would be good for Judy. He comes from a solid missionary heritage”.

In December of 74 Aunt Pearl passed away from cancer. Two years later my parents were married and two years after that in 1978 I was born.

Five years ago today Rachel's mom, Barb Yutzy, lost her battle with MS. I knew I wanted to write something about her today, but I wasn't sure how to do it. I never met Rachel's Mom. And how do you show honor to someone you have never met?

From what I have gleaned about Barb from Rachel and her family members, it seems to me that these three women were made out of the same stuff. Part of what links them together in my mind is that they all lived roughly the same number of years, Aunt Pearl 55, Rachel's Mom 60 and Bea 62. But deeper then that was that all three loved and served the living God. And the thing that truly humbles me is that there is no doubt in my mind that when they were alive, all three of these women prayed for me, specifically. Bea's prayers are a huge part of my role here at LSU along with countless other ways she prayed for me and the other students from Iowa State. Although Aunt Pearl died four years before I was born she had to have prayed for “Judy kids” some day. And how many thousands of prayers must Barb have prayed for “Rachel's future husband”. And these are the seeds sown into my life.

Hebrews 12:1 “Therefore, since we are surrounded by such a great cloud of witnesses let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked before us.”


How I long to live a life the reflects the faithfulness of those who have gone before me.

Valentine primes

There are two candles. There are three sections of candies. Each section has five candies. Two candles plus 15 candies is 17. Oh the chimichangas and the desert that Rachel made for Valentine's day were both awesome.

I hope my story was a gift to you. =D

Crawfish with my in-laws


Rachel's brother Mike was in town with his wife Helen, his daugther Sam and his Grandson Xander. We went out with them out for some of the local grub. Good times.

Three in the morning is a great time to post.

Season's Greetings friends and family. We are about to leave the Red Stick (Baton Rouge that is) and heading towards the Red Lake. I turned in my grades for my Calc class late last night. I can't believe the semester is over. We are hoping to get on the road very close to 4 AM central time. We will see many of you very soon and some of you even sooner. =P

We drive 14 to 18 hours today to get to my parents house in Eastern Iowa. Then we "sleep in" on Monday to continue north at 6 AM. I am excited about driving through Northern Iowa. We are meeting Lori Adams for breakfast. She has been a good friend of mine for over 10 years now. She was the coordinator for my mission trip to to Uganda back in 02 and she prayed at our wedding this summer. I am looking forward to some time that Lori and Rachel can get to know each other a bit.

So 9 hours or so of driving to spend Monday night in International Falls with Rachel's brother Sheldon and his family. Finally we ONLY have 6 hours of driving on Tuesday to arrive in Red Lake Ontario.

* Pray for safe travels. Pray that the 30 plus hours in the car would be a time the strengthens and deepens our marriage. And pray that the time over the next 3 weeks with friends and family would renew us both for the coming year.

Hope to post again soon.
