Silk



Maybe when you think of silk you think of the Silk Route from China, of the cocoons - which by the way I saw I think for the first time in my life last week- and of whatever silk scarfs you have. Interestingly enough this week I'm going to try to assemble silk. Yes, silk. All these years I hasn't realised how biocompatible silk is. After all they use it for sutures, it is no more immunogenic than any synthetic polymer, it forms strong intertwined fibers, and a soft gel. I just started reading about it and it's an exciting material. Monday is coming, I need to prepare for my experiment. For a change, I'd like to see things working.

Elections



Last Sunday there were elections for mayors, city councils and prefecture councils in Greece. Which raised two main questions in my mind. The answers that I've gotten that far are not that intuitive.

1. How does the community deal with the fact that mayors deal with some large amounts of money but most of them have no management knowledge (beware: I am not using the word "skills") How do we, as people, control the mayor's deeds? Should the state be prepared to host at least a short term course to teach these people some basics ? Or is just learning by doing the best method (I vote for the former one)

2. Why are the elections in the U.S. on a weekday? Doesn't that decrease the chance of working people to vote? Even though they are allowed to get time off work to go vote, do many do that? Understanding the extra financial cost, wouldn't it make sense to have the elections in the weekend like all the other countried in the world?

If you have answers please let me know.

Common ideas



First of all, thanks to my friend Josh who offered his thoughts on grading. I already started to make solutions promtly, and changed the maximum score of the exercises. Let's see if that is going to make students distracted from grading and focused to learning. Also, he just wrote his thoughts on math books, math problems and the quality of thought that goes into the mathematical education of middle and high school students (see Oct.13). I totally agree with him. Our high-school math textbooks, were not bad, but just not enough. I remember ho everyone was trying to find in the beginning of each academic year books new, old, even from our parents, to complement the understanding and do more exercise for the exams. But, the problem is that none of these were REAL math books. I think my first real math book was not even considered a real math book (E.T.Bell, 'The Mathematicians') it was short biographies along with the major work of a lot of prominent mathematicians. Then, I read Gleick's 'Fractals' and then by Van der Waerden a book on Egyptian, Babylonian and Greek math. Not a real math book either (it falls into the category of history of science). The point is that doing trigonometry is school is OK, it's necesary, but I understand why it cannot be fun. Not even the so-called real examples will make math more understood (not to mentions how underdeveloped is the 3D thinking in a lot of students and how painfully they discover once taking vector analysis in college, while so easily they could have been introduced to the concept of geometry and stereometry) But, the joy of math comes from understanding concepts, mainly abstract, mind games, even making with ruler and compass a hard construction.

And off to what made my past week hard. Last May when studying for my quals I cme up with a beautiful idea relating proteins and microfluidics. I ahd no idea how to find my material, or how to observe it, but I somehow knew that the experiemnt would be cool, not that hard to actually do, and could open up the field for new questions.
Later this summer, in Germany I came up with a nice way to make networks of "vessel-like" micron-scale pipes in natural extracellular matrix proteins. This I knew how to do, but it was not the right time to do, since I was in Germany to learn sth completely different.
Last week I was at a lecture at which a professor was asked about his latest reearch project. I couldn't believe it. It was exactly my May idea. An they had preliminary data.
The week before, I had gone to another talk where I found out that my little netwrok system has been done, with a few problems, but has been done.

You know how sometime is the history of Science you come up with equations, proofs and ideas that two people published independently the same time? I always wondered: first: how could they not know that another person in their field was working on the same exact problem, and second: how probable is that two people come up independently with the same idea at about the same time?
Apparently, neither shoud be surprising to me. I didn't know that someone in the same university had done sth I was thiking of doing. And I didn't know (there was no way I could have) about the fact that someone this past spring came up wit hteh same idea as I did. Maybe because we all are interested in similar problems, and because the needs of the medical community and the techniques we use are the same, we will with probability = 1 end up working in (partially) overlapping problems. The question is to come up with a lot of ideas. One of them will be innovative. Remember my (Microsoft) T-shirt? "Think" " Impact"

HBA-USA transfer program



It's been more than a year now that the idea of one person has become a small but healthy organisation. The Hellenic Bioscientific Association of the USA, of which I am a board member, now has 208 members, mostly graduate students, professors and researchers in the biological, biomedical and other health related fields (from medicine to public health).

Well, that's no news. What is news is that we have up and running a student tranfer program for students of the Greek universities who would like to spend some time in a lab in the US, doing research, gathering experiences while getting paid. We even have our first four applicants! But the reason I'm writing about this transfer program here is to encourage you (yes, you) to tell your greek friends to at least check it out. We would like to establish this program, make it well known, help students and make our organisation respectable in the eyes of the American scientific society.
It is one project of the many that we are trying to start. Other programs include postings of positions, encouragement of collaborations and I hope a forum where the members can interact directly.

I hope you tell your friends know. I personaly think it's a great opportunity.

The pain of grading


Shame on me (honte (?) sur moi) for not writting for so long.
I mean, now that Ahmedinejad has a blog, I know that fewer people read mine...but I should keep up the good job!

This past weekend I decided that it's a good time to look for a roommate starting January. OH MEIN GOTT. What a pain! I mean, everyone seems so pressed as if they are oving into the apartment tomorrow! Calm down people, it's for 3 months later. The other thing is that you need to make sure that they don't find sth better in the meanwhile. Contract? First rent? I'll see. Let me first choose an interesting roommate. Oh, I'll definitely keep you updated on that!

The truth is that I've been trying to be productive during the week, and really unproductive during the weekends to make up for the week.
For example, this Saturday I was trying to learn Vaggelis how to sail, which clearly worked well, except this single point in time when Vaggelis was trying the jibe and after hearing a quite scared "get down!" from me since the boom was comng directly to his head, he bends not only down, but also forward. Clearly, the mainsheet came to his neck and the image was Vaggelis trying to put his head in the guilotine...
So, trust me...I can teach you how to sail. These small out of balance details are only to spice up our lives :)

The other (hard) reality is that I have to grade. Yes, and while I like teaching, explaining and trying to convince my Fluid Mechanics 27 students that the buoyancy does not depend on how deeo you've emerged the object, I don't like grading. I mean, after all, they usually know when they've looked up the answer at the end of the book, or whether they fussed around and did things messy to try to get partial credit. So, why are we here grading? Like absolute monarchs we say "2/10, 5/10", "Good job", "see solutions" etc...
Anyways, I just hope this semester passes with them learning fluid mechanics, me training in patience and trying to sneak of grading to do some of my experiments.

I heard Google has a chat that has rotating emoticons...! Cool!
I have to talk to Christine. She told me about them...
