Wed - November 18, 2009A Coffee Maker a Chemist Would Love....Here's my Birthday Present from Brian, it's a
coffee siphon.
Isn't it pretty?
The coffee syphon has everything a chemist would love: 1) cool glassware, 2) shiny clamps, 3) boiling fluids, 4) a vacuum, 5) open flame, 6) an elaborate ritual, and 7) coffee. What could be cooler? This method of brewing coffee, which was very popular in the early 20th century disappeared in favor of simpler methods like instant coffee (ie. beans that have been cremated) and automatic drip. The way this works is simple. Fill the bottom reservoir with water. Put the burner (not shown) under it and begin to heat. Place the filter & coffee in the top reservoir. Once the water begins to boil, the steam will push the water up the siphon tube and through the coffee grounds (by which time the water has cooled slightly to just below boiling, the perfect temperature for rendering out yummy coffee flavor compounds while leaving the bitter compounds behind. Once the brewing has been going for a minute or so (depending on the strength you want), remove the heat, the steam cools and condenses creating a vacuum in the lower bulb, sucking the coffee through the filter and into the lower reservoir. Can't wait to try it! It's a little more involved than my handy, dandy press pot, but it's got an open flame, cool glassware, a vacuum, bubbling and hissing. What's not to love? Posted at 09:57 AM Fri - November 13, 2009The Incident ...The Large Hadron Collider is out of service yet
again.
This machine located outside Geneva was designed to search for the particles that may have existed only at the very earliest moments after the Big Bang, and to look for particles that, at this point, are only theoretical, including the Higgs Boson. The collider has had numerous problems including: 1) a group of scientists who proposed it might create a black hole that will swallow the earth (someone did the calculations and the probabilities of that happening are small), 2) then after it was turned on there was a coolant leak and it had to be shut down for repairs, 3) then one of the scientists was arrested, and 4) the latest problem is that it was shut down when a bird, it is believed, dropped a piece of baguette into an electrical substation. There's nothing particularly strange about all these problems.... Or is there? *cue scary music* Some physicists are suggesting that the universe itself is causing these problems. Based on their mathematical theories, the creation of Higgs Boson may be prevented by the future because the Higgs Boson should not be created. One of these physicists states, "you could explain it by saying that God, in inverted commas, or nature, hates the Higgs and tries to avoid them." So perhaps there's another force at work here. There always has been. It's undeniable. We've all experienced it. Everyone ... has witnessed events that they cannot fathom let alone explain away by rational means. Puzzles, deciphered in prophesy. Our loved ones ... dead, risen ... Whether we want to call that God or Gods, or some sublime inspiration, it doesn't matter. It's here ... it exists! But of course, such a theory would lead one to ask, "What does 'God' need with a Large Hadron Collider?" So I have a better theory. If you look at this cool picture of the Large Hadron Collider, you probably won't notice anything out of the ordinary. It's just a cool picture of the collider, with some guy way down in the front to give it a sense of scale.
Nope. Nothing unusual there. Or is there? *cue scary music* If you zoom in, you'll see something interesting.
Hmmmm....

Posted at 10:05 AM Thu - November 12, 2009Overheard on the Diag...On many warm(ish) fall days from noon to 1PM there
are often rallies of one sort or another on the Diag. Yesterday there was a
rally about global climate change. They even hand a band playing. As I walked
across the Diag on the way back from Starbucks, I got to hear the refrain of the
band's song: "Cow farts break my
heart."
Not exactly Shakespeare, and now it's stuck in my head. Drat. Posted at 08:28 AM Wed - November 11, 2009Best Conference Paper Ever...I was watching a recent episode of House last
night in which House delivers a paper at a conference. Wilson actually wrote
the paper as a confession because he felt guilty that he'd enabled a terminally
ill patient to commit suicide. Anyway, I've been to lots of conferences and
seen lots of terrible talks (plenty of good ones too.) But even the good talks
rarely get the attention they deserve. So I've decided to use the following
opening for any talk I give at any conference ever, regardless of the
topic.
"Euthanasia: Let's tell the truth. We all do it." If that doesn't grab people's attention, nothing will. Posted at 12:17 PM Sat - October 31, 2009Wed - October 28, 2009Liftoff...Today the US tested its first new rocket design
since the Space Shuttle, the Aries I-X. I
suppose I should say "newish" since the Ares system is based on Shuttle parts,
primarily the solid rocket boosters. It is the tallest rocket we've built since
the Saturn V took men to the moon.
It isn't clear yet what NASA's priorities are going to be under the Obama administration, but this vehicle would be used to get to the International Space Station (USS Good Money After Bad) and to park objects in low-Earth orbit for retrieval during longer missions (to the Moon, or Mars). The second stage along with the Constellation crew module were just mock-ups for this test. ![]() Posted at 01:36 PM Tue - October 27, 2009USDA Grade A Prime ... uh ... coffee?This morning, this was written on my
coffee:
Which led to several questions:
1) Which half of the calf? 2) What's the other half? Coffee? Milk? Marrow? 3) Now that Starbucks has taken over American coffee, is beef next? "Coffee, it's what's for dinner." or "Great coffee comes from happy cows. Happy cows come from Starbucks."
Posted at 08:10 AM Sun - October 18, 2009Michigan Football...
I have a confession to make. I've been a student at
The University of Michigan on and off for most of the time between 1993 and a
month ago. And I have never been to a University of Michigan football game.
I've never even been in the Big House. Hello, my name is Alan, and I'm a loser.
In my own defense I would like to point out the many U of M hockey games I've been to, so I'm not a total poindexter. But hockey games seemed more fun because they're at Yost, a relatively small and seriously rowdy place. Everything I'd heard about U of M football games was that they were pretty boring and quiet. I guess the new renovations at the stadium have changed that because even though they weren't setting any attendance records, it was still pretty loud. But even yesterday, a game which was a total blow-out, was actually fun. It was fun to see 5th string guys get a chance to play in the Big House, and it was fun to see their opponents, from a small 5000 student school get to play there too. U of M didn't exploit the situation, but instead sent out the bench to give almost everyone a chance to play. It was actually a pretty surprising moment of sportsmanship. Posted at 06:46 PM Wed - October 14, 2009Methods and Materials...from boingboing:
Why you should always read the methods and materials sections of scientific
papers. The money quote from a journal article examining the effectiveness of
chicken soup to inhibit neutrophil
chemotaxis:
"Traditional chicken soup was prepared according to a family recipe, which will be referred to as 'Grandma's soup.'" There's also another example about necrophilia in fruit flies. Funny stuff. Posted at 09:38 AM Mon - October 12, 2009Libraries...These days I get annoyed when I have to walk the
200 feet from my building to one of the libraries on campus because I can't find
a book or article online. But there was a time when I actually liked libraries.
The library in my hometown, for example, was built like a Greek Temple to books.
Though the collection was limited, it still took me several years to read my way
through their science fiction section and I always enjoyed going
there.
Old libraries like that are hard to find, but Sunday we took a brief trip after church down the street to one of the newest public library branches in Ann Arbor, the Traverwood Branch. We had seen a special about the construction of this library on the local PBS affiliate and the architecture looked cool, so we decided to go check it our for ourselves. You can see pictures here. The interior features a lot of wood, mostly ash that was taken down from the construction site itself. (The emerald ash borer has decimated ash trees in southeastern Michigan, so harvesting these trees was actually doing the world a favor.) The idea behind the building is that it should be functional, but also be built out of sustainable materials and be as green as possible. They've certainly gone out of their way to make it attractive as well. If more libraries looked like this, maybe I wouldn't be so ornery about having to go to one once in a while. Posted at 12:45 PM Fri - October 9, 2009How to Make a Smoothie...Longtime readers of this blog will know that we're
big fans of Alton Brown's show "Good Eats" on the Food Network. Saturday Alton
is having a 10th Anniversary special and so he was on Jimmy Fallon's show last
night promoting it (and his new
cookbook).
Alton and Jimmy made smoothies using simple, common equipment that anyone would have laying around the house. Enjoy: Best line of a cooking segment on TV ever: "This is not how you die. This is how you learn to live." Posted at 10:02 AM Thu - October 8, 2009More on Marriage...As I mentioned here,
the PCUSA Special Committee on Marriage and Stuff is soliciting recommendations
to be added to its special report on marriage and other stuff and
things.
Here's our letter regarding our recommendation: “In essentials, unity. In
non-essentials, liberty. In all things, love” --
Augustine
“God alone is Lord of the conscience” -- Westminster Confession of Faith, 6.109 October, 2009 To the Committee: Grace and peace to you from God the Father and the Lord Jesus Christ. Thank you for your continued service to our denomination. We have read your preliminary report and while we find much to disagree with, we will ignore those disagreements and submit our recommendation regarding Christian marriage in the faith community. We have only one recommendation: 1) Be Presbyterian You note in your report that the denomination does not agree on issues relating to same-sex marriage and civil union. You also acknowledge the need for mutual forbearance. We agree on both points. Thus your recommendation to the denomination should, in the spirit of mutual forbearance, not force anyone to violate his or her God-given conscience on an issue that is not now, nor has ever been an essential of the faith. To wit, no pastor, or layperson, or session should be forced in any way to participate in any marriage ceremony with which they do not agree. Traditionally, pastors in the PC(USA) have always had the discretion to decide for whom they will and will not conduct a marriage ceremony and this should not change. In the same way, no pastor should be forced to refrain from officiating at a marriage ceremony for a couple simply due to the gender of the two individuals involved. In other words: freedom of conscience. Quite simply, we should continue to be Presbyterian. There is nothing Presbyterian about instituting from the top down a clerical class that dictates how laypersons in the church must live their day-to-day lives. There is nothing Presbyterian about forcing people to act against their consciences on non-essential matters. We Presbyterians warmly welcome any who proclaim Christ is Lord to come to His table. We Presbyterians warmly welcome any who proclaim Christ is Lord to be baptized. That is all very Presbyterian. Why then, if we allow such freedom of conscience regarding our two sacraments, would we not allow such freedom of conscience for a marriage ceremony that is not a sacrament and is not essential? By following our recommendation to “Be Presbyterian” both sides of these debates would, for the first time, be able to exercise their freedom of conscience. To those who disagree with us, we say, “If you don’t like gay marriage, don’t get gay married.” We do not seek, require, nor expect their approval any more than they sought or required our permission when they got married. No one is asking those who disagree to violate their consciences; they are free to disapprove as much as they want, as often as they want, as loudly as they want. They are free to invent specious rationalizations and fictitious harms that will supposedly arise from a wedding they were not invited to, of two people they will never meet. However they should not force the whole church to countenance their fabrications. So, to those who agree with the person who recently wrote to the Presbyterian Layman, “Irrespective of what the policy wonks force down the Church’s throat next, where I serve, marriage will be between one man and one woman. Nothing else,” we respond, "Fine. No one is asking anything else. We only expect the same forbearance from you." That’s very Presbyterian. To our allies, we say, “If you want to get married, you cannot force anyone to officiate at the service or host the ceremony.” The answer to this impasse really is that simple. The solution merely requires everyone to kindly mind his or her own business, a habit that is unfortunately rapidly disappearing from both civil and religious society, including in our own denomination. If that very Presbyterian (and not coincidentally very American) notion of live and let live is what you mean by mutual forbearance, then both of us are all for it. However, if by mutual forbearance you mean one side of the church gets to continue to enforce the anti-gay status quo through continued cynical threats of schism and through intimidation by drive-by nonsense litigation, while LGBT Presbyterians and allies are forced to violate both their own God-given consciences and Scripture, then we believe that to recommend that they cheerfully agree to their own continued oppression is un-Presbyterian and is nothing like real forbearance, nor is it remotely realistic or workable. So, we hope that you will look to traditional Reformed, Presbyterian understandings of church life in making your recommendations to the denomination, and be guided by both Augustine, and the Westminster Confession: On matters involving non-essentials, God alone is Lord of the conscience. That is our recommendation. May God continue to bless you all as you finish your work. Posted at 03:54 PM Thu - October 1, 2009Big Book O' Knowledge...The bound copies of my dissertation arrived
yesterday.
I figured I'd take a picture, since this is likely the last time they'll see the light of day.
Posted at 11:13 AM Wed - September 30, 2009Life on the other side..."It must be nice to be done" has replaced "When
will you be done?" as the phrase I hear most commonly these days. Done, that
is, with graduate school.
Yes, it is most definitely nice to be done. So now I'm teaching, which I haven't had the chance to do for a while, and it's great fun, even if I'm teaching more of a herd than a class (~350 students in the lecture hall. However, it's an 8AM class, so only about 25% of the herd is awake at any one time.) It's funny how students adapt. The kids who are engaged and ask questions gravitate toward the front, so by the 3rd or 4th lecture, it is more like teaching a class of 30 in front of a studio audience of 320. I should take boxes of Rice-a-Roni to class with me. I just finished writing the first exam with my colleagues teaching the other sections. This is real chemistry, so the tests ask real chemistry questions. That means getting four instructors to agree on good questions and just as importantly, good answers to those questions, within the confines of what is reasonable for these students to know, which takes some time. I think students would be alternately horrified and amused and surprised to see their four instructors debating the possible answers to questions on a test. I can almost here the shouting, "But shouldn't you guys have this all figured out by now?!" The notion that all this should be cut and dried, and have one precise answer isn't realistic. It's a fun process, though, probably not one that would inspire great confidence from first year students (though it should). No one wants to see the sausage being made. Meanwhile.... Writing research proposals to send out in order to find jobs. Trying to get data collection going for another research project. Trying to rip apart my dissertation into publishable chunks. So there's plenty to do, probably just as much as before, but it is definitely nice to be done. We went camping over the weekend, and one of the other guys at our site brought along his readings from his graduate class. Yup, it's nice to be done. Posted at 12:17 PM Tue - September 22, 2009There's Just No Pleasing Some People...Saturday evening we were walking down Main Street
in Ann Arbor, on our way to meet friends for dinner. As we walked down the
street some probably drunken, obviously corpulent, definitely douchbaggy
football fans yelled from their enormous Earth-destroying SUV, "You two should
be holding hands!"
Well, that sounded like a good idea, so we did. Apparently they didn't actually know what they wanted, because then they completely freaked out over this. It took them about 2 minutes to wrap their pea-brains around what was going on (football Saturday, traffic was slow and so were they) and then they started shouting "fag" at us, of course. (I avoid arguing with lunatics as often as is feasible, but for future reference, that's Dr. Fag to you.) Well, if they didn't want us to hold hands in the first place, why did they suggest it? There's just no pleasing some people, particularly drunken football morons. One might have expected such behavior from the opposing team, but these were Michigan fans. Anyway, this reminded me of a situation a few weeks ago at our favorite watering hole. We were there with a friend, waiting for the rest of the group to join us for our usual Friday evening libations & dinner. One of our friends is a hard-working family physician, and he'd had a long week of delivering babies, so he had his feet up, using Brian's knee as a footstool as we sat there chatting and enjoying our cocktails. After a while, the maître d' came out and told us that someone had come in requesting a seat away from "those guys out there who are hanging all over each other" or something to that effect. Note: I find PDA creepy actually, and have never participated in any overt show of affection in public that I wouldn't be completely comfortable with my grandmother seeing. I am, in this regard, actually quite a prude. Anyway, the cafe was nearly empty both inside and out, yet the maître d' told this person that everything was full. Heh. Then came out and told us about this jerk. Our friend promptly removed his feet from Brian's knee until the maître d' told him, "Oh, no you don't, put your feet back up there." My message for the neanderthals in the truck or at the cafe: Welcome to Ann Arbor. This is our town, not yours. Walking into a cafe complaining about the gay clientele? Are you actually so stupid as to believe that is going to be effective when I would guess that at least 50% of the male employees in service industry jobs in this town are gay? Or do you think shouting "fag" out of your SUV is intimidating? I don't know which bog you crawled out of, but there are twice as many fierce fags in this town as their are douchbags like you, so I'd suggest you watch yourself. Listen, the lines at our restaurants are already long enough and the traffic on football Saturdays is already bad enough. So if you don't like it here, I'd suggest you go back to whatever backward backwater you crawled out of and free up some parking. Thanks, kitten. Posted at 10:29 AM |
