My Europe Trip: Tentative Schedule

It looks as though the schedule for my talks is:

4/14 Belgrade: ESFL
4/17 Prague hosted by Institute of Cryptoanarchy and Paralelní Polis
4/19 Bucharest
4/21 Sofia: Bulgarian Libertarian Society
4/24 Budapest
4/26 Maastricht: MSFL
4/28 Oslo: Capitalist Party in Norway
4/30 Oxford: Oxford Union

I would appreciate it if the people hosting the talks would check that this fits their view of the schedule and let me know if I have anything wrong—coordinating this many talks can get confusing.

I would also like information for each talk on where and when it will be, assuming that's known, and whether it will be open, so that people reading this blog who happen to be in the area can come to any open talks if they wish. Also the identity of the hosting organization if I don't already have that here.

I don't seem to have any detailed information from Ste in Bucharest, so would appreciate an email from him or a comment here with his email address.
(Email received, Bucharest talk definite for the 19th)

Wanted: Beta Readers for a Novel

I have completed a draft of Brothers, my third novel, the sequel to Salamander, and am looking for beta readers. Both books are fantasies of the sort where magic is a science.

Beta readers may, but need not, have read Salamander. I am interested in how well the sequel works both for those who have and those who have not.

My Europe Trip in April

I have been trying to work out the details of my speaking trip next month, complicated by issues of how to get from point A to point B in Europe. The current fixed points are the three weekends:

April 13-15 ESFL Belgrade
April 21 Sofia
April 28th Oslo

I have at least tentative invitations to speak in:

Maastricht, Netherlands
Prague, Czech Republic

My first thought was that Maastricht was close to Oslo so I should go there a couple of days before my Oslo talk. A little online research showed me my error--distance in miles, distance in hours, and distance in dollars have only a loose relationship. It is faster and less expensive, as best I can tell, to fly between Maastricht and Warsaw, Maastricht and Barcelona, Maastricht and Rome, ...  than between Maastricht and Oslo.

By my calculations, I have time for four more talks, assuming one day for travel between each pair of talks. It looks as though all of the likely locations other than Maastricht have reasonably good air connections to each other and some of them have tolerable connections to Maastricht.

The next step is for anyone who wants a talk and is willing to pay my expenses–a hotel room plus air fare to their location from whichever of the other locations I end up flying from–to let me know what days would work and what city I would be flying into and out of. I can then calculate a reasonable schedule.

Alfred Marshall on the Use of Mathematics in Economics

I retired at the end of last year and have finally finished clearing out my office. In the process I found a number of interesting things, including a printout of a book on transport economics that I wrote thirty some years ago when teaching a course on the subject but never published and thought was lost.

I also found the original of a passage in a letter by Marshall that I have been misquoting for many years. Here it is.

Balliol Croft, Cambridge
27. ii. 06

My dear Bowley,

     I have not been able to lay my hands on any notes as to Mathematico-economics that would be of any use to you: and I have very indistinct memories of what I used to think on the subject. I never read mathematics now: in fact I have forgotten even how to integrate a good many things.
     But I know I had a growing feeling in the later years of my work at the subject that a good mathematical theorem dealing with economic hypotheses was very unlikely to be good economics: and I went more and more on the rules—(1) Use mathematics as a shorthand language, rather than as an engine of inquiry. (2) Keep to them till you have done. (3) Translate into English. (4) Then illustrate  by examples that are important in real life. (5) Burn the mathematics. (6) If you can't succeed in 4, burn 3. This last I did often.
     I believe in Newton's Principia Methods, because they carry so much of the ordinary mind with them. Mathematics used in a Fellowship thesis by a man who is not a mathematician by nature—and I have come across a good deal of that—seems to be an unmixed evil. And I think you should do all you can to prevent people from using Mathematics in cases in which the English Language is as short as the Mathematical.....
Which leaves me wondering how much of the economics of the next century went into Marshall's fireplace.
