    ps. For someone contemplating a career in academia, I can reccommend "Ms. Mentor's Impeccable Advice for Women in Academia" by Emily Toth. Nominally, it's aimed at women in academia, but the advice is applicable to everyone. Lots of the issues there are more on the humanities side rather than the science/engineering side, but it's a good resource and a quick fun read.

    Tenure evaluations and expectations vary widely across academic disciplines, and different fields have different publishing rates. Numbers such as "x articles per year" are going to vary alot. 15 articles is nothing for some fields in psychology, and two papers is a lot in some fields of mathematics. Still, a tenure evaluation depends upon 3 main components:
    1. Research/scholarship: papers published, external funding, patents, projects, etc.
    2. Teaching: undergraduate and graduate courses, supervising graduate students (if applicable), developing/revising courses
    3. Service: helping to run the university/college by serving on committees, having adminstrative roles, doing a fair share of the unpleasant work of administration

    At a strong research university, the research component is all important and unless your teaching is a complete disaster, you'll get tenure with strong research. At other institutions, the factors are weighted according to the role of the institution. At many places, a reasonable but not strong research record is adequate if there is good teaching, and a weak classroom record is fine if you are a strong researcher. At primarily undergraduate institutions like liberal arts institutions (in the US), teaching is the most important aspect together with at least some nominal amount of research or scholarship, construed broadly. At every institution that I know, service is something that can help a weak tenure case, but only very rarely is a good service record the main basis for a positive tenure decision.
  4. strong variation with fields on Most Science Studies Tainted by Sloppy Analysis · · Score: 3, Interesting
    There are a lot of different attitudes about the role of the anonymous referee, in different fields and in different settings. In computer science and mathematics, where most of my publications are, the role of the referee depends upon a number of things. A few comments relevant to my disciplines:

    • The responsibility for correctness lies with the author, not the referee. It is good if the referee spots problems but it is not the obligation of the referee to certify that every last detail is correct.
    • Often, the primary responsibility of the referee is to comment on the importance, priority, relevance and how much interest there is in the work.
    • In the CS world of conference refereeing (as opposed to CS journals) there is often absurd time pressure. Articles/abstracts are due at midnight local time on some date, so things are typically hastily written, and referees must review things in a very short timeframe and practically never get a chance to check things carefully. As far as I am concerned, the conference publication model in CS is terribly broken. There have been some calls for reform, but those have been coming for at least the last 10 years or so and over that period it's gotten worse, not better.
    • In math, it can take a year for a referee to work through something techical, so the process is slow.
    • Typically, referees are uncompensated for their work. Some people take their refereeing duties seriously, and some do not. Generally, those who do a good job in a timely fashion are asked more often to referee more things, which is not exactly a reward.

    At many institutions, those with good outside funding are rewarded with teaching fewer courses. The typical courseload in a strong research department in science is generally lower than that of a strong research departemtn in the humanities, as the grants tend to be much larger (and much more essential) on the science side, especailly lab sciences.. If you ask a typical engineering prof "would you rather have a lighter teaching obligation or have the students get a tuition reduction?" I think about 99% of them would opt for less teaching.

  15. just about anything with proofs on What Math Courses Should We Teach CS Students? · · Score: 1

    There are a number of suggestions already mentioned, and to be honest, there is a huge range of courses that would be valuable. A standard weakness I see in CS grads is poor exposure to analysis of algorithms and computational complexity. CS students often struggle with those topics because of either poor preparation in discrete math or not enough exposure to mathematical proofs.

    As far as getting good experience with mathematical proofs to my mind, just about any pure math course which is interesting to the student and has some emphasis on proofs would be useful- combinatorics, algebra, analysis or even topology or logical foundations. Getting comfortable with mathematical proofs will serve CS students well, not from the particular topics covered necessarily, but from making complete (hopefully concise) arguments (proofs.) Being able to express your arguments precisely and convincingly is a very important skill. People will judge your development and coding skills through the window of your communication skills so doing as much as you can to improve your ability to communicate mathematically/precisely will work well.

    If you are looking for a valuable course from a range of possibilities, don't underestimate the "shop around" method for electives. Depending upon how your institution's registration process works, you may have the opportunity to sit in on a bunch of possible course the first week and decide which professor/subject matter appears to be most valuable. Typically, there is a great deal of variation from professor to professor, so you may find it more valuable to take a course where the topic doesn't seem immediately applicable, but which has a professor who can communicate the mathematics well and who can help students develop their abilities to prove things.

    having your own text as a required book for the course can easily be FAR worse than this.

    Absolutely! At reasonable institutions, the convention is that when a faculty member has as a required text his or her own book, the part of the proceeds from those sales go to a departmental account for cookies for grad students, or something comparable and neutral. I have been at many institutions, some have reasonable conventions like that, and at others, the faculty member just takes the money, which I think is unethical.

    In the one case when I required one of my own books as a text, I was at a less than reasonable (OK, terrible) institution where the convention was to just take the money, and when I decided to give the money to the departmental student travel fund, I was attacked by other faculty members for making them look bad. That is, making it clearer that they were the slimy weasels they are. Am I glad that I got a professorship at a much better institution!

    Ancedote from that terrible institution: for more than one of the faculty authors there, the only place in the world where that text is used is there, so almost all of the faculty members' book revenue (it's not much, BTW, just because the book costs $100+ doesn't mean the faculty member gets much at all) came from being required in that institutions' courses (and these were terrible books.) And there was pressure, of course, for other instructors to require those same terrible texts, ugh!

    BTW, for all those people who think that textbook publishing is the ticket to riches and fame- good luck! What it takes some time to realize (and many people never realize) is that writing explanations that students can understand and get much from is quite difficult, and most people are not good at it. Just because you can give great lectures (a much more interactive setting, even if there are no questions from the students) doesn't mean that you can write a decent text. There are some people who simply are much better at writing useful texts than the rest of us. Those people should write textbooks, and the rest of us should stop.

  18. personal economic choice: privacy at a cost on Car Owners to be Notified of Blackboxes in Vehicle · · Score: 1
    It would be interesting to see privacy decisions about the use of data from black boxes treated as an economic commodity, rather than as an absolute right. That is, why not have a choice, for example in car insurance, how about a multi-tier system for pricing for a year of coverage:
    1. $1000/year and you do not agree to divulge any information from car electronic data recording devices and can rip them out if you want
    2. $500/year and you agree to divulge any information EDR info relevant in an accident and keep the devices operable
    3. $200/year and you agree to constant uploading of EDR and GPS data from your car

    These numbers are totally invented, of course, but guess what most people would choose: option 3, at least if the popularity of supermarket discount cards where giving lots of personal information saves you some some money on groceries. If people are willing to trade privacy for discounts, why not let them?


    The point is that though you may have a "right" to keep somethings private, but you also cannot expect to hold onto that right vigorously and get bargain-basement prices on things at the same time. Insurers would presumably be happy to have more data to charge rates which more accurately reflect their risks. If you willingly provide data that shows that you drive under 65MPH all the time, etc., in exchange for lower rates, that seems like a reasonable plan.

  19. Mike Brown's take on this on IAU Proposes 3 New Planets · · Score: 5, Informative
    Mike Brown, leader of teams that have discovered 2003UB313 and 11 other objects that meet the proposed definition of planet, has the following on his webpage now:


    The IAU proposal officially recognizes only 12 planets; where does the number 53 come from?

    By the proposed IAU definition, anything large enough to be pulled by its own gravity into the shape of a sphere and which is in orbit around a star is a planet. The proposal officially recognizes 12 planets (the nine previously recognized plus Ceres and Pluto's moon Charon plus 2003 UB313) creates a complex committee procedure for an object to become officially recognized. This part of the proposal is perhaps the weakest. In no other area of astronomy is there a definition for a class of objects and then a committee that has to decide if an object fits the definition. There are simply definitions. If an object fits the definition it is part of the class. If the IAU proposal is accepted then scientifically all of the spherical objects out there are indeed classified as planets, regardless of how long it takes for a committee to officiailly declare them to be so.


    A relatively simple analysis show that there are currently 53 known objects in the solar system which are likely round. Another few hundred will likely be discovered in the relatively near future. Regardless of what the official count is from the IAU proposal these object all fit the scientific definition of the word planet and if the scientific definition is to have any credibility they should all generally be considered planets.


    What should the public think about 53 planets?

    Most people, when first confronted with a proposal to make 44 new planets in the solar system, seem to react by looking blankly for a second, then shaking their heads and muttering something about astronomers being crazy. Astronomers are not actually crazy, at least most of them. Astronomers have needed a good scientific definition of the word "planet" for many years now and this one works well for scientists. It doesn't, however, work terribly well for the rest of the world. The solution is the one that should have happened long ago: a divorce of the scientific term "planet" for the cultural term "planet." No one expects school children to name the 53 planets (most, in fact, don't even have names). If I were a school teacher I would teach 8, or 9, or perhaps 10 planets and then say "scientists consider many more things to be planets too" and use that opportunity to talk about how much more there is in the solar system. But at the end of the day I would talk about 8 or 9 or 10. Not 53.

    Culture and science have always meant something different when they use the word planet, and with this new scientific definition so clearly far removed from what the rest of the world things a planet is there will no longer be any need to confuse the scientific word with the cultural one.


    How am I going to vote on the IAU resolution?

    This one is easy to answer. I am not an IAU member, I took no part in drafting the resolution, and I get no vote. If I were to vote, however, I would have to decide that while the definition itself is viable the extra non-scientific beauracratic barrage attached to the resolution would doom it for me.

      One think that may help here is some sort of collaborative effort, where whole bunch of people work on a textbook together. That way no single individual needs to put that much time into it.

    In my experience, textbooks written collaboratively tend to be worse than those written by a single, capable author. Students have a hard time reading a text, and if the "voice" of the author changes, even sublty, this can make it harder. My experience with this is mostly from a wide variety of calculus and engineering math texts, and may not apply to other discplines as sharply, but most students really struggle reading the text. Most professors, unfortunately, have a hard time judging texts' readability as they already know the material and are often more concerned about other aspects of the text than whether or not the students will find the text readable. I know many many faculty who have thought that they could write a better calculus book than the standard ones, and all those texts either are never completed or end up being terrible for a variety of reasons. One of the publishers I work with reports something like less than 10% completion for texts they enter into contracts with overall.

    most of our textbooks were basically just lecture notes written by our professors and printed by the university press, and most of them were very good.


    In general, if the lecturer and the author of a text are the same person, that is a very good thing. The emphases, notation, and overall approach are very likely to coincide and be more cohesive. As a student in the course, the text seems natural. But with a different lecturer, those same notes may be quite inpenatrable.


    so maybe the "snazzy 3d figures" and other stuff like that is actually a total waste of effort and money.


    Having been on a number of textbook selection committees (blegh, I wasn't quick enough to say "Not it!") unfortuately these things have come to be expected. Again, faculty often are not capable of making good judgements of how readable a text is to a moderately prepared student, and oftenn make judgements based upon (to my mind) relatively spurious issues like order of topics, notation used, or whether or not they will need to revise their notes extensively.
