I'm no Cal Ripken or Ernie Tyler!

I am proud of the fact that I have not missed a day of school or work due to illness or injury since 5th grade (and that may have been questionable).

However, I am no Cal Ripken Jr.. Ripken is being inducted into the Baseball Hall of Fame for good reason. He played in 2,632 consecutive baseball games, and he was a great player.

However, Ripken is no Ernie Tyler. Ernie worked as an umpire attendant for the Baltimore Orioles for 3,769 consecutive games. Not bad. He is missing his first games ever to attend Ripkens induction into the Hall of Fame.

Rack 'em up

I had a busy beer weekend that was long overdue. I bottled my ESB and transfered the three other batches to secondaries.

That took a lot of busy work.

By bottling my ESB I had an empty carboy (remember my beer lineup). I borrowed a friends 5-gallon carboy which I used to hold my sanitizing solution so I could use it for all three carboys.

The process went something like this: I emptied the ESB carboy, cleaned it and added the sanitizing solution. After a bit of a soak, I transfered the sanitation solution to the borrowed carboy and racked the next beer to the freshly sanitized carboy. I repeated this process two more times.

I used Star-San as my sanitizing solution. According to the MSDS, Star-San is 50% phosphoric acid (H₃PO₄), 15% dodecylbenzene sulfonic acid (see below) and 10% isopropyl alcohol (the remainder is a secret, though the majority is probably water).

I presume the phosphoric acid and IPA kill anything living in my carboy and the dodecylbenzene sulfonic acid acts as a detergent.

11111

I just signed in and my site meter was at 11111. That was weird.

That converts to 31 in the decimal system, but telling you that would flag me as a nerd.

Why I was able to become a chemist

Paul at one of the premiere chemistry blogs just wrote a post on why he became a chemist. This got me to thinking, "why did I become a chemist?" Well, that got me to thinking about not why I became a chemist, but why was I able to become a chemist.

Sure, having a brain helps. Having parents who encourage you to read instead of watch TV really helps[1]. Having parents who encourage you in general to study and learn really helps.

I always had a natural interest in science. I was amazed at how things worked, natural and man-made. By the third grade I was determined to become a neonatal surgeon. Obscure choice for an 8-year old? Yes, but true nonetheless. I would wear my pajamas backwards because they looked like scrubs. I never changed my mind until I was lured away in college by the mistress that is "Chemistry."

Yes, I was one of those pre-meds we in academia all really love to love[2]. I was slowly lured away by chemistry, but the final nail in that coffin was when I took Advanced Organic Chemistry during J-term. Brutal and hardcore, but I loved it.

But, how did I get to that point? Well, I was prepared very well. Here are a few of the most important individuals in my academic training that made it possible for me to become a chemist.

Mr. Willems in high school. I had him for Biology, Chemistry and Physics. He did a lot with a limited budget. He was very well organized and orderly. He didn't just teach us facts and trivia. So much of today's HS curriculum deals with learning about facts and trivia[3]. Mr. Willems taught us to think through problems using basic principles. This is a skill that has helped me greatly. Of course, there are some facts that must be memorized. One of the most valuable things he forced us to memorize in Chemistry was the names and formulas of the common polyatomic ions. This proved to be incredibly valuable later in my college career.

Mr. Bolda in high school. I had Mr. Bolda for most of my HS math. He was also my track coach. He was your prototypical nerd that many HS students tend not to embrace, but he was a very good teacher. One that, despite his mannerisms, any reasonable student would respect[4]. I did respect him. This was in the days before every HS in the world offered AP calculus. What Mr. Bolda did offer was a solid foundation in trigonometry and problem solving. I still use the problem solving skills he taught us in HS. I got to college with the skills need to breeze through most of a math minor.

Mrs. Kjeer in college. Staying with the math theme, I had Mrs. Kjeer for almost all of my college math (calculus I and II, differential equations, multivariable calc...). It was my very first day of college, 8AM class. We walked into our classroom and were met by this young and attractive calculus teacher who seemed to be hopped up on too much caffeine. This was NOT what we were expecting. When we got into the class, we learned quickly she knew what she was talking about and she wasn't hopped up on an alkaloid. She loved what she was doing. This coupled with uncompromising standards, an infectious excitement for calculus and the ability to back up what she said inspired us. I took as much math from her as I could. This helped me in ways I don't even realize.

Mrs. Weberg in college. Finally, I get to an actual chemistry professor. Mrs. Weberg inspired many students to become chemists, and provided the tools to do so. I had her for General and Organic. Mrs. Weberg was a great teacher. She knew what she was talking about and knew how to get students to learn. However, most importantly, she was like a mother to so many students. She was a very nurturing person and it wasn't always in the lovey dovey way. She was a mother after all, and she knew that every now and then, the best way to motivate a student is to kick them in the butt. She was stern when she had to be and compassionate when she had to be. We learned as much about life as we did about Chemistry. What she did was create a situation with clear standards and the motivation to reach those standards.

There are others to be sure, but these are four of the more important ones for me.

In retrospect, all of these individuals had some common traits. They loved what they did. They had high and uncompromising standards. They provided as much support as a student may need or request. They realized there is life outside of the classroom.

I try to model how I teach and interact with my students around what these individuals did. I usually fall far short of what they did, but I try.

They are why I was able to become a chemist.


[1] Don't get me wrong, I watched a lot of Transformers and He-Man back in the day...
[2] Some of the words in this sentence are inaccurate.
[3] Read your states expected education outcomes.
[4] Of course, not all HS students tend to be reasonable in this regard. Mr. Bolda eventually quite teaching. I do not know where he is now.

Keeping beer cold.... A science project

There are a lot of ways to keep beer cold. But, what is the best?

Check this out to find out. I'm most impressed that they used PBR. It won a blue ribbon once!!!!

It turns out, a beer cozy made out of Rice Krispie bar is the best.

Don't ever tell me the internet isn't full of useful stuff.

My partial mashing method

For those of you interested, the following is my partial mash method. Feel free to critique. I went all-in on this technique by brewing 4 batches with this technique before ever tasting the results. I'm not worried. I'm sure the beer will be quite drinkable.

About 3 pounds of grains (pale malt, 2-row malt and/or others) are added to about 1.5 gallons of water at 164° F. The goal is to mash at 152° F for about 90 minutes. To maintain the temperature, I place my nearly full kettle with lid into a larger kettle and fill the larger kettle with water at 152° F. This larger kettle is meant to act as an insulator. It works pretty good. I usually need to heat the apparatus once during the 90 minutes to maintain the 152° F temperature.

After the mash, it is time to sparge (filter and rinse). I filter the grains by using a plastic colander lined with a muslin bag. See the following (the Michelob Golden Light can is there because that's what I was drinking around the 4th of July):



I use about 2 gallons of water at 168° F to sparge the grains. I slowly pour the hot water over the grains about 300 mL at a time.

This method seems to work well. I get to a reasonable original gravity. I have not calculated how efficient this method is. I need to first see if it makes good beer or not.

I'm back

I'm back. We survived a week of camping in the northernmost parts of Minnesota.



Time for reality to take over. I spent an entire week without using my computer once. That was nice.

I will post a few details about the trip later. Specifically, I want to sing the praises of DEET (Meta-N,N-diethyl toluamide).
