Polygons

May 26, 2007

Julie Rehmeyer reports on some recent progress in polygon research of the following problem:

What is the polygon with the largest area that has n sides and fixed diameter?

The progress is for the case of even sided polygons of side 10 or more–numerical optimization software have apparently been used in the research. Take a look!

Ethics–too important to be left to philosophers?

May 26, 2007

Janet Stemwedel and Adventures in Ethics and Science tackles the question:

It is possible that learning ethics (even ethics-for-scientists) from a class in a philosophy department will have less of an impact on science students than learning ethics from their science professors would have.

I have seen other versions of the same question too, in its various forms, asked: where do we want our students learn their mathematics? their communication skills? their writing skills? their reading skills?

The answer, in my opinion, is that a 101 level course should be learnt from the specialists–namely, in the departments of philosophy, mathematics, communication, language etc; it should be  followed up by a course in the mother department. Works wonderfully; in addition, it also gives the students a perspective of what aspects of the same problem are  emphasised by the different disciplines. For example, a student who does a course on partial differential equations in a mathematics department, in a physics department and in an engineering department has a better chance of learning about three different approaches to the same problem–at least, it did to me, when I did a mathematical methods course in the chemical engineering, physics and mathematics departments.

“The time has come,” the Walrus said,

“To talk of many things:”

Science

  1. A philandering string theorist is caught by his wife with another woman. “But darling,” he pleads, “I can explain everything!” — Sean while writing about String theory, and how it is not dead yet!
  2. An interview with Walter Isaacson, the author of the most recent biography of Einstein;
  3. I just can’t skip “coffee can prevent …” type research results;
  4. Tonal intervals in music and the underlying physics of the vocal anatomy;
  5. Sexual orientation and the performance of mental tasks;
  6. A must-read review of the book Cognitive foundations of muscial pitch;
  7. Chet on why primary texts in science are not the best way to learn it–I would tend to agree after my attempts at reading Gibbs — most of the time, I guess the difficulty relates to the change in notations, terminology and the way the field itself has developed — in that sense, like all books, scientific classics are also products of their time;
  8. Chad at Uncertain Principle discusses whether you should plunge right away into data aquisition, or, automate the process; and, Janne, in the first comment to the post, discusses the analogy (which popped into my head when I read the post) of doing by hand or writing a script of computer programmers; like Chad, I too take the script route only when it becomes too much of a pain doing things by hand;
  9. Bora’s Linnaeus birthday post and a real celebratory post!
  10. Dawkins on the many aspects of time (via, who else?)

Literary

  1. Kalevala–The Finnish National Epic (via);
  2. News of a new Sister Pelagia novel (with a link to a 30 page excerpt);
  3. Favourite fonts of some writers; via;

Economics

  1. A B-squared podcast of an interview (mp3) with the author of More sex is safer sex: The unconventional wisdom of economics, Steven E Landsburg;
  2. YouNotSneaky calculates the jerk factor needed for opposing immigration; via;
  3. What are the goods whose price should not be forbiddingly high, asks Thoma, and gives a list too in answer.

Fun

  1. Here is a video of (a rather youngish) Govinda and Kimi Katkar as superman and spidergirl respectively (via B-squared). I loved the vyuung…vyuung sound effects! Makes me long for Hindi movies at IISc gym!
