Now I’ve also been to Latvia – or to the airport in Riga at least. SAS had overbooked my flight from Copenhagen to Dublin Wednesday morning so they offered me a very nice compensation to go with airBaltic from Copenhagen to Riga and from there to Dublin. Only a 3 hour delay, although Riga is in the total opposite direction…
Just the page you need when you can’t remember the critical value for a 90% C.I. for Students two sided t-distribution: Probability Distribution Functions. You choose deg. of freedom and the probability-level and the script returns the critical value. Kewl.
This is one of my personal favorites. The picture was taken in March or April, 2007, but it was not developed and scanned until last week; inspired by Gerry Winogrand, I like to wait some time from shooting a roll to developing it. (As an aside, Gerry Winogrand, when he died, left behind nearly 300,000 unedited images, as well as more than 2,500 undeveloped rolls of film.)
One good reason for waiting is lack of time. Therefore, I usually gather around 10 rolls of film before I bother to develop, because it takes some time to prepare the chemicals etc. (Once the chemicals are mixed and the temperture adjusted to 20 degrees I might as well process 10 rolls while I’m at it.)
The second reason for the wait is the lack of a high-quality scanner. On my budget I can only afford a crapply flatbed scanner and that’s not good enough for my M6 (oh no, the best deserves better :-). Recently, I learned that this place let Imacon scanners by the hour. So I went there. It costs 400 Dkr. for 10 hours, but the scanners are also the very best – an Imacon Flextight cost around 100,000 Dkr.
Finally, and perhaps most importantly, when I forget when, why, how etc. I took the photograph I tend to become a better critic of my own work.
By the way: The picture was shot on a Leica M6 with a 28mm Elmarit lens. The film was Kodak TriX 400. I don’t recall the shutter and aperture settings, but I guess somewhere around 1/60 sec. at f/2.8 (it was around dusk). You’ll find a bigger version in my Flickr-account (link on right).
For those of you who will be in and around Copenhagen tomorrow, Sunday the 23rd, DSB’s gonna make you an offer you can’t refuse:
Free S-train rides. Read more about it here.
Now I know why people marrie.
Marriage is apartnership for the purpose of joint production and joint consumption. Other important factors are
* division of labour to exploit comparative advantages or increasing returns (e.g. one partner works at home and the other in the market, and it does not take twice as long to cook dinner or wash for two as for one)
* sharing of collective, non rival, goods such as children or a house
* extending credit and coordination of investments, e.g. one spouse works while the other studies
* risk pooling (one is sick or unemployed and the other works)
So I guess that divorce is the result when the list of benefits above becomes smaller than the costs. Or maybe there’s more to it than that :-)
Played a Danish baseball-variant at a seminar with some colleagues this monday and sprained my right ancle. Not a big deal, but I still went to the emergency room to get it checked.
But…danm…I had to wait 4 1/2 hours before a doctor could see me!
Assume that’s the average waiting time in the Danish emergency rooms and also assume that the hourly wage of a visitor is roughly DKR 150. Then the 933,610 visits in 2005 would have introduced a death weight loss of
4,5 x 150 x 933,610 = 630 millions.
I honestly hope my assumptions are wrong!
So, does number and size of particles in the air have an effect on the health of persons living in cities? And if so, how much more more dangerous is it for city-people to run or bike in open-air that for people in towns and villages?
An american study (citet here, but unfortunately in Danish) shows that city-women has an increased risk of cardiovascular illnesses. [Here I could come up with a long story about the problems of causal inference from observational data, but I'll resist the temptation :-)]
This page has some data on the level of air-pollution in Copenhagen.

By the way…this post is motivated by fact (1) below and the fact that I have exercised my favorite sport – running – around 3,300 minutes or 650 km. in Copenhagen since April.
