Happy New Year

You may wonder what kind of weirdo calendar I'm following. Or, indeed, what I did with myself for several months.
The answer to the first question is that I always feel September first as the beginning of a new year. A vaste expanse of months, and weeks, and days, and minutes, in which I can try and experiment with something new, something better. This year I'm particularly energetic due to extremely long vacations (I will not tell you how long, lest you commit the sin of Envy).
The answer to the second is that I had very long vacations, and got to spend a lot of time with my children. This has led me to seriously reconsider my work strategy. I am now planning to reorganize so as to become more efficient and have more time for my kids. And for my husband. And for my students.
And, first and foremost, for myself. Happy New Year, everybody!

January madness

I spent most of the Christmas vacation visiting family members (actually my husband's family). It was pleasant and relaxing, and would have been perfect hadn't I gotten a really nasty sore throat on Christmas day. After some attempts to find a doctor who would be willing to make house calls, I found some antibiotics at home and just took them for a week. I'm happy to say that I'm feeling well and the rest of the family enjoyed perfect health.
Now the situation is as follows:
1) a long boring job I had planned to do during the vacation is still to do;
2) I'm teaching 8 hours/week, on two advanced courses that require a lot of preparation;
3) there are a number of funding deadlines in the very near future;
4) there are overdue papers to write;
5) there are submitted papers to rewrite;
6) there are a million of recommendation letters to write;
7) my daughter is getting dental braces soon;
8) my husband has communication issues with a student and needs (and gets) help;
9) I still have to plan a scientific trip which involves getting a visa.

On top of this, we are having the most appallingly bad (cold/windy) winter in 10+years..

I just want to curl up somewhere and sleep until spring comes.

Back to everyday life

This week is the first normal week. All students are there, everybody has reached (I hope) their final office, and I have no official travel scheduled for the next few months.

On the other hand, my private life is full to the brim. Tonight, dinner at S#9's with my whole family (he actually likes kids) and his mother - who's a math professor herself. Tomorrow, to the movies with C#1, a friend and the friend mother. We will see Mamma Mia! Next weekend, London tour with C#1. Next week, I'll be part of a theatre show, reciting part of the declaration of the rights of women. This last event is particularly pleasant, since it's a direct effect of female lobbying, namely having dinner with most of my female colleagues (unfortunately, though more than half were present, we didn't need a particularly large table).

Now I just have to finish two overdue projects, but I find it incredibly hard since all I want to do is work on my New Pet Project. I have even chosen what journal to send the paper to :-).

Oh, and there are no comments at all about the Obama election because I tend to talk when I'm grumpy.

Like in the old days

I feel young again. Today I took a long (9+ hours) train trip, since taking the airplane woudn't have been so much faster. To complete the deja-vu feeling, the second train was 35 minutes late. So I missed the third, and ended up spending one hour chatting with a friend of my college years in front of the station, under an unseasonably blue sky.
The unfortunate side effect is that I'm completely exhausted.

To justify the label mathwork, I'll add that:
1) I did work during most of the journey;
2) purpose of said journey is participation in a scientific conference.

I hope that on my way back the three-train system will work somewhat better - or this time I'll end up speding the night at my friend's place.

Big changes

Actually, big changes are usually evident to the outside world: a member more or less in the family, a new abode and/or job. Here nothing so momentous has happened, but still a feeling of revolution is dominating me.
The most obvious event is that the twins have started school. C#2 has already achieved basic reading skills (in the native language, which is one where the connection between written and spoken is almost bijective).
C#3 is not so far, but on the other hand he's officially the second best player of "Fusball" (Tischfussball/calciobalilla) in our household, and I have to concentrate pretty hard to maintain my leading position. At least the long hours of training in my university years have now helped me gain the respect of my son.
My daughter C#1 is taking both english and german lessons this year. Since the summer she has obtained a weekly allowance, and yesterday she spent some of it for the first time. She bought a "Teach yourself spanish" book. All I can say is that deep in my heart my 8-year-old self is dying with envy.

But the main change is that I'm putting order in my life, inside and outside. I've organized my new bedroom, formerly known as family storage area (what used to be mine is now C#1's). I'm not yet done, but I'm on my way to have a snug home office. And I've reorganized my office. Not only can one finally see the floor, and the cleaning ladies have actually started to clean it, but I know what's where - well, there are still some piles of junk I have to go through, but I'm definitely improving.

Last week I had my first (small) political victory in my current "leadership" position (the one half of my colleagues thought I was unfit for). This required a lot of organizing, but I'm quite happy with the result and especially with my choice of allies. And a colleague told me that I've managed to change my speech style: he said I sound much more professional.
I'm also starting to work together with the very few other female professors; that's particularly useful since we're distributed across fields and can give each other inside information on what the other groups are thinking.

And tomorrow I'm going to a conference: I have a pleasant and productive week in front of me.

Busy days

Yesterday I had an administrative meeting. It started at 9.30 am, paused for 15 minutes for lunch, and at 4pm the rest of it was rescheduled for tomorrow morning. This morning I lectured two hours; I'll spend most of the afternoon doing oral examinations, and I'm giving a talk tomorrow afternoon.

I spent last Saturday socializing with C#1's schoolmates and their parents, and Sunday caring for two more kids than usual while their parents took an afternoon off. They offered to have my kids Monday evening, so that I could have a date night with my husband. When I arrived home Monday in the late afternoon, C#1 had sprained her foot, so my friends took care of C#2 and C#3, while we spent our "date night" queuing at pediatric emergency ward (five days of rest, than good as new).

I definitely need summer vacations, but that has to wait until mid-July.

I should have spent the day on the beach

Today the weather was gorgeous. Sunny, dry, with just a few white clouds to make the sky prettier.
And I feel I wasted it. I barely managed to prepare my lecture (because of discussions with students), gave my lectures, talked with students/postdocs/colleagues the whole afternoon. And now I am too tired to do anything useful.
Luckily the weekend is on its way.

Sunshine

This morning was a bit more work than usual, since C#1 had a guest for the night, her tall, blonde friend CelticPrincess. It was hard to convince them that bedtime had arrived. This morning, however, they behaved very well and went to school on time. We might soon organize a double visit, with CelticPrincess' brother (aka CelticPrince) also spending the night - he's the same age of C#2 and C#3, although significantly larger.

I spent some time organizing the children's summer activities, the family vacation, and booking visits to a house we may want to buy(!). I then gave a lecture, talked to a number of students, and have yet a few more meetings before I go pick up C#1 (who has two extracurricular activities on wednesday afternoon).

What is really really useful is my new computer, my first tablet pc. What used to be my own lecture notes, scribbled on several sheets of paper which promptly got lost, is now an editable file which all of my students get a copy of. Which means that in later years the same notes can be used for self-study, or to organize a student-run seminar. I just wish I had bought it earlier.

And if next weekend the weather keeps good, it's time to go to the beach. I love summer, even when it's still spring.

Long time no see

A lot has happened since. Students S#3 and S#4 graduated, and they got postdocs for this year and next year. Also, S#6 who's graduating in 2008 already has an offer (and more to come - he has done a great job). S#6 had a brilliant idea, with a great statement and a bogus proof. I hope that soon she'll get the proof right. S#7 is also doing pretty well. So altogether I have now three students, since S#6 will probably never graduate, but become a brilliant teacher instead.

I got some administrative responsibility, which I'm making a mess of, but not worse than the previous holder.

On the family front, C#1 likes gymnastics much better than she did basketball. She has a new maths teacher and her problems with the subject seem to vanish; nevertheless, she seems to have inherited my reading style and not my math love.
To give you an idea, she got one 350-page book as Christmas present. She finished it yesterday morning, and at lunch time she was on page 250 of the second reading. She doesn't look like me at all, but she's definitely my daughter :-).

C#2 speaks german fluently, if rarely. He still can't write his own name, and complained that Santa brought a game with letters but none with numbers. C#3 is trying to write more and more, and we're confident that a breakthough on the diaper-in-the-night front is also near in time.

We had a lovely Christmas + Boxing Day, just the 5 of us plus nine-year old neighbor J as a bonus elder sister. We played bingo and Monopoly and two different versions of Labyrinth (ours and hers) and baked cookies and ate them. C#2 expressed as further wishes to Santa that C#3 stop crying so much, and that mama would tickle him (C#2, that is) more often. The second wish has been granted :-).

Mostly, I'm wondering whether to move to a scientific blog in my actual name. I feel that there are not enough women scientists blogging in their own name, and there are not enough mathematicians of any gender. Speaking of which, I'l include two great examples of math blogging: the latest John Baez, with a commented list of free math books online, and John Armstrong with a lovely "Yes, Virginia" Christmas post. Of course if I could write like either of them (both in style and depth) I would definitely blog under my own name.

In related news, C#1 figured out that it's not Santa that brings the presents. She looked very proud of herself, and not shocked at all.

Students update

It seems to get slowly better. I have now read four of five pages of S#7 and it is all pretty reasonable. She is a bit creative with conventions for my taste, but I have to admit that the meaning is at all points totally clear. That's really good.
Unfortunately, tomorrow I will have only half a day for mathematics, since the afternoon I'll be busy with the birthday party, and the rest of the week I will attend a conference with the aim of improving my cv, not my mathematical culture. At least I should meet an old college friend, who chose a different side of mathematics and whom, as a consequence, I see rarely indeed.
I am also optimistic that S#3 and S#4 will finish their dissertations and get a postdoc; in the moment S#3 has a postod and S#4 a dissertation, but improvement is in the air. S#2 got a new postdoc, and a long well-paid one. Since S#1 chose to be a teacher, and S#5 has chosen to leave mathematics, I don't feel as bad as I did. And in a few weeks the number of students that I am responsible for will go down to four, two of them shared... I feel so excited, if I'm not careful I might as well accept another one!

Intense week

I didn't do any research this week. I spent several hours doing support to the students. I should be happy that they are getting productive, but this means a growing pile of mostly badly written and occasionally wrong theorems accumulating on my desk.
I wasted an outrageous amount of time doing university politics. I may or may not have an official administrative duty in the future (I hope not), but I will have to invest a lot of time doing brown-nosing, which is the officially certified method to get poitions in one's own field in my university. It is very sad, but I'd rather submit to the indegnity that have my student suffer from me being overworked; plus, one deserving young person will get a good job, if I play my cards right. Still, part of me hopes to move eventually to a better and more honest place, if one exists.
I dedicated some time to maternal activities: I went to a meeting with the schoolteachers, planned a birthday party, and (drumroll) finished sorting and packing the enormous backlog of no longer needed clothes in our flat. Plus, I managed a trip to Ikea and bought a large amount of no frills storage funiture; when it will be delivered (by Ikea) and mounted (by WS, with some paid assistance) I expect a much neater household. I already reorganized C#1's clothes cupboard, and the twins' is due tomorrow. Mine will have to wait for a new, unbroken cupboard. I am still overdue in organizing the children's extracurricular activities: C#1 wants to try a new sport, for which she needs a medical certificate, C#3 will do violin, or swimming, or both, and C#2 will most likely sit on a chair and suck his index finger.
Next week I'm off to a conference, and after that courses start. I am wondering when I'll start to do research again, and hoping that it won't be too long.

Alternatives

In the past two days I spent a nontrivial part of my time and most of my energy discussing hiring policies in our insitution with a number of people, including all the colleagues in my research group and the head of the whole institute. The result is that important information has not been forwarded, and other has been "lost". As a result, a position which we had planned on advertising soon also got "lost", and someone who is in his late forties, married and with a child on the way might or might not be given the tenure track position that was informally promised to him years ago. The same position that prevented him from getting an offer anywehere else "because we know you're going to be hired at XXX".
In particular, I am faced with the following two alternatives:
1) ether the head of the institution, or the head of my research group
is
2) either a liar or imbecile.
I am trying to decide which alternative I like less. Or more.

As a side remark, the head of the institution said several times that I am "cute" and referred to me by a diminutive form of my first name (say Venny instead of Estraven) which in our language would only be appropriate for a child.

I got too many invitations to conferences. When am I ever going to write a paper again?

Half and half

I spent this morning being a mother. Or maybe a Übermother, considering that I had three guest kids visiting: one girl the age of C#1 and two boys the age of C#2 and C#3. I managed to do two washing machines, hang one and a half, clean up the kitchen, and prepare enough lasagna for everybody: all this in my spare time from the main activity, i.e., preventing the kids from killing each other and destroying the flat.
I am pretty proud of myself, and view this as an investment in the future (at some later day, the parents of the guests will be taking care of my kids). I only regret that I didn't get to eat any of the lasagna, so I had to grab a sandwich and a coffee before facing the afternoon as scientist.

  • 2-3pm: discussion with the consultant for european grants. I did learn something, in particular that I just missed a deadline, but also that there is a very interesting call coming up in January 2008 and one in May. I just can't believe I can produce a decent proposal in time.
  • 3-4pm: student S#6 tells me about the new reference he has found, and the progress he expects to make about that. We discuss some projects about how to organize his work in the next months.
  • 4-5pm: S#4 and I go through the Nth version (for N>100 - she has at least one a day) of her thesis. Some of the major problems have been solved, but she still has a writing style too close to physics. Improvement is evident and I try to be optimistic.
  • 5-6pm: S#3 and I go through his proof of something which I thought should be obvious but ended up not being so. It seems this time he has really fixed it, but some further adjustments are needed (especially "easy" details). I hope for best and we plan to meet again on friday.
  • 6-6.50pm: S#9 tells me he has finished working out the details of the proposition we discussed last time. The result is pretty much of the kind I hoped it would be. I outline what the next steps are supposed to be, and we start discussing the table of contents of his thesis. He might have proven everything he needs to prove before Christmas. Then we discuss which techniques he should use to prove the remaining steps. At 6.50pm his alarm goes off and he tells me I should go home. He is that considerate.
  • 6.50pm: I call WS and ask him to go home. I also tell him what edibles our refrigerator and our deepfreezer contain.
  • 6.50-7.30pm: continue discussion with S#9, including which school/conferences he should attend and when precisely he needs to have a readable, preliminary version of the thesis ready - and why.
  • 7.30-8pm: wasted time on the internet in a desperate attempt to unwind. I feel like I don't have a brain any more.
Many thanks to Sciencewoman for having this idea of charting down how to use your time.

Home improvement, and other weekend employment

I spent a lot of the weekend planning changes in the way our flat is organized. It is reasonably large, at least for the standards of the country I live in, but it's totally messy. Some of the cupboards don't open and close properly, and a few drawers are really in bad repair.
I don't have the time to go looking in different shops, plus WS and I like Ikea furniture anyway. So I spent several hours over the weekend searching the Ikea catalog and checking online whether the stuff was actually in the store. As usual, the store nearest to where I live has only about a third of the stuff listed on the catalog, so I will have to face a really long drive.
WS does most of the mounting, but he hates choosing. So I just took all the measures, made plans, ad showed him a list with the final result. He then suggested a few changes, but basically approved: we have known each other for almost two decades and can estimate pretty well what each other likes.
The main aim I have is that the children learn to keep their own stuff in order: to do that, they have to know where things should be put, and everything has to be easily accessible. Some signs of slow improvement are already visible: they did put away some toys, after being asked and being told which box they should use. I also did some tidying up so that now all the Duplos are together (I should buy Legos soon, I know - but I first need a good box!).
And I can't very well complain that they don't keep the books in order when there's entirely too little shelf space for their books to fit in. I wonder how other parents face this problem; C#1 laments that she doesn't have enough books, that she has read them all and is totally bored.
I spent a couple of hours supporting WS's mood, too. This involved listening at length to the precise symptoms of his latest ailment (he hurt his own shoulder doing sports) and hearing all the details of his latest research project, which is very far from the overlap of our scientific interest and required really a lot of focussing on my part.
I also spent two hours helping a visiting colleague who is going to be here for a month: I picked him up at the station and showed him around, politely explaining that yes, some people here might speak english, but he shouldn't count on it. Maybe I shouldn't have done that, since he's not visiting me at all, but I felt kind of sorry for him; the person who invited him will not be back for a few more days.
Finally, I am proud to say that with ten days still to go, the list of stuff to buy for the new school year of C#1 (which has been stuck on the fridge since June) has now been completely ticked off. Everything is ready. Fall may come now.
Still, I hope I will manage to go the seaside next weekend.

It's not an end, but a beginning

Here the world as we know it has come to an end. If I were writing german I would say that we have a Super-GAU (it roughly means the worst possible disaster, one which is out of control): the nanny took an extra, unauthorized-but-paid week of vacation, and the summer camp canceled the current week. So we (or, in this case, I) have the kids with me the whole day. Of course the weather, hitherto perfectly sunny, has decided to turn bad precisely this week.
I spend part of my time doing children shopping for the winter, like school stuff, shoes, and clothes, and some in my office, trying to get something done while the kids sink in an orgy of DVD's. All this interspersed with playground hours and organizational meetings with other parents for childcare and birthday parties.
A very beautiful essay I read long ago (I can't even remember what language it was in, much less the author), suggested that "It's not an end, it's a beginning" is a good guideline for any official speech: at a graduation ceremony, at a wedding, a retirement party, and even at a funeral. It applies well now, as the academic new year's eve approaches fast.
In particular, I used the occasion of being stuck in my office with a blaring cartoon movie to tidy it up and make order. I produced four large boxes of waste paper and three bags of junk, and my office looks much much better now.
I asked WS to throw away it all for me while I staid in the office with the children. He did it after receiving the following instructions: the boxes of waste paper go in the paper recycling bin; the bags of junk go in the general junk bin; you have to go there with the car since it is too far away to walk; the car is in the parking lot. Sometimes my spousal interations vaguely remind me of computer programming.
As I type, the children are colouring cartoon pictures on my desk, and I am trying to concentrate on doing some marginally useful work. I find it very hard to concentrate with all kids in the same room: legend has it that Euler could do research while kids played on his lap, so in principle it's not impossible (maybe that's how he got to publish as much as he did).
This year is really supposed to be a new beginning for me. I am reducing the number of students to a level compatible with my advising ability, I am going to spend some research time abroad with the whole family for the first time since the twins were born, and I am hopefully going to do some serious writing, both in research and on expository matter. I am cautiously optimistic. Happy New Year to everyone!

Love thy colleague

I was very surprised when, a few days ago, I read in a comment by Count Iblis on Am I A Woman Scientist?'s blog that he manages to write papers with people he has never met. Since I have done plenty of collaboration with people who were physically far away, I stopped, and asked myself why I found it so strange.
The answer is, of course, that all my co-authors have been friends; indeed, we were friends or at least good acquaintances even before we became co-authors. Indeed, the relationship goes both ways: I have expanded my research field in certain direction, in order to read papers by people I found interesting, or even so that we could collaborate. On the other hand, I have become a close friend of researchers I started talking to because of pure scientific interest.
Indeed, more is true: I tend to think of the mathematicians in my field, those that I have known now for one or two decades and that I occasionally meet somewhere in the world, those that I invite to my conferences and whose papers I referee (and conversely), as my "village". That is, the place where I am at home; where people know me and accept me as I am, including plenty of problems (when I read of people complaining about slacker co-authors... well, that's usually my role).
Although I still keep contact with some of my pre-university friends, they are not so many, and the contact is infrequent. The friends I've kept for three decades now are those who at least try to understand why it is reasonable that I occasionally leave husband and children behind and travel to another town, or country, or continent, to try and prove theorems.
My social network in the town were I live tends to be composed of other parents with a university culture and a taste for books. Some are scientists in other fields, others are married to scientists, and all have some kind of curiosity or at least respect for the world of science; they are my models in my attempts to do public outreach (attempts that include this blog, of course).
So there's one part of balancing work and love, the brain and the heart, that I find very easy: namely, a lot of the people involved are the same.

This post is written for , whose next edition is Aug 1st at Twicetenured.

It's that time of the year

Several weeks of summer vacations await me. So of course there has been a tremendous last-minute rush of things to do, especially since everyone else seems to have left at mid July. So I was the only one to answer the phone when questions arose from the administration.
Also my research students wanted extra office hours (we are talking of something like a total of three hrs/day in the last two weeks).
The paper with PD#1 and S#6 is finally ready. I am very, very happy with it, even though it is not a very great result. It is one of the few cases where I started with an idea of my own and saw it become slowly true. Of course I wouldn't have made it without my coauthors, but still it was my dream first.

I have said a bit too many times "yes" in the past few months, which means that I have agreed to write a number of non research articles of different kinds. I had the brilliant idea of planning to finish them all during the summer vacation: after all, for two weeks we are visiting my parents, and for one week we are going to a hotel with childcare.
The trouble is of course that my parents aren't willing to look after the children unaided for longer than 15 minutes, if at all, and that in previous occasions the hotel's children entertainment, while highly appreciated by C#1 and C#3, failed to satisfy the more discriminating taste of C#2. As a result, I was free to do any activity which could be performed while having on my lap 16 Kilos of child and/or running after said child who was obviously in training for some daycare level survival training.
So I will just summarize here the list of articles I have agreed to write, so that I can look at it occasionally:
  1. an expository article on a topic I know very well, but from an angle I am not familiar with;
  2. a short autobiography for a site about careers of women in science;
  3. a short article on the relation between women and science for a magazine with a mostly medical audience;
  4. another expository article on a topic I know very well, but which completely lacks readable references;
  5. a short expository article on part of my recent work;
  6. a short expository article about what I hope will become my future area of research;
  7. a very short article on the life of Emmy Noether, of which I know very little.
Due dates are basically all in September, but I should plan in finishing during the vacation, because afterwards the doctoral students will need even more time. And, I will have to seriously start nagging C#1 about her homework (last year she didn't do any... and WS isn't really very good at this kind of things, so it's my chore).

Headache is over

I am usually a very healthy person, and become easily obnoxious when faced with even the slightest physical inconvenience. I spent the last three days with a continuous headache, resistent against the usual painkillers I have at home. I have a very vague recollection of said three days, except that the weather was gorgeous and the children enjoyed every minute of it. Of course the culprit is the sun: I will have to get a hat. Sigh. It usually takes me no longer than three days at the beach to lose or destroy one, and most of them are too small anyway.

Today I finally woke up feeling normal, and I was so giddy with relief that I celebrated by doing almost nothing so far. That is, I talked to WS about something he needs to know for his current project, to a visiting scientist who explained to me some references I overlooked, to PD#1 and S#6 about our paper and in particular said references, to S#8 whose thesis is progressing really well, to S#4 who now should start writing up what she did in a reasonable way, and to FP1 and FP2 about some technical questions on Calabi Yau threefolds. As a result, I haven't started writing anything yet today, and I still have so much to do.

Tomorrow I will be in late - the new dishwasher should arrive - and spend one more hour attending a (hopefully interesting) talk by the visiting scientist. I also have to help WS plan an expansion for his research group which would also involve me and a rather interesting chunk of research money. Next week we have a very distinguished visitor, and then I'm going to go vacationing. Three weeks. I can't wait.

Writing science versus writing mathematics

Dr. Freeride at Adventures in Ethics and Science wrote a post inspired by the book A Short Guide to Writing About Science by David Porush. She quotes from that book a list of "commandments" for scientific writers. I'm going to comment on that list from the perspective of a mathematician (the only one I have!).

  • Complex sentences are more precise and intelligent than simple ones.
  • This is definitely not true. Indeed, I have had to learn to keep it simple, since mathematical english uses much simpler structures than my native language. This is a clarity requirement, particularly needed since for most of us english is not easy.

  • Passive voice is more objective than active voice because active voice involves stating the agent, who is often a human, and humans introduce subjectivity.
  • Passive voice is never used, except in extremely straightforward contexts.

  • Descriptive prose is imprecise and unscientific because descriptions rely on adjectives which are often unquantifiable.
  • You can't possibly use descriptive prose in a statement or a proof, since mathematical language is so overpicky. On the other hand, descriptive prose is welcome in introductions, and everywhere else where you are trying to give euristic comments (which should be included!).

  • Claims about scientific fact must always be cautious; thus, using very cautious language -- squirrel language -- in scientific prose is always prudent.
  • We fine tune caution when we state conjectures (we have several synonyms, referring to different degrees of confidence). But when we prove something, there's no caution: we are proud of our achievement and we're totally sure! Occasionally mistakes are found, usually before physical publication.

  • Be as wary of innovation or taking chances in language as you are in the lab.
  • We need new words all the time! We both use standard ones with new meanings (a ring, a field and a module all have a precise definition) and invent new words (my favorite is crepant, as something for which discrepancy is zero). Finding good words to describe new concepts is one of the key duties of mathematicians.

  • Revision is unnecessary because knowledge is transparent.
  • What can I say? Some of us don't revise. They are hated by the whole community. The vast majority does.

    In the comments, someone discussed whether things might have changed since Porush published the book in 1995. Maybe, but not in mathematics. We stopped writing complex sentences around roughly 1950 (reading older stuff is a pain, in any language) and the rest is even older. The only exception is the passive voice, whose perceived difficulty is in my opinion language-dependent.

    Maybe mathematicians are really different from other scientists: e.g., the difference with physics is pretty noticeable even at the stylistic level.

    In a hurry

    Today I talked to S#3, whose thesis project is unfortunately very, very slow. I told him to come back in two days. I had again a large number of meetings; I attended a talk by a very successful former graduate student of a colleague, and in the few spare moments started preparing the final version of the paper with PD#1 and S#6. I also achieved a very minor result from the point of view of visibility of my group within our department.
    And now I'm going to have dinner out to celebrate PD#1 leaving us soon for a tenure position!

    PS Lest I seem too efficient, I did skip one meeting. So I will have to read the notes tomorrow.
