BIRS (Banff, Canada)

I was fortunate to recently spend a week at the Banff International Research Station, for a conference on Whittaker Functions: Number Theory, Geometry and Physics. Rather than talk about the mathematics, I will concentrate on the facilities in this post. BIRS has been successfully running many maths workshops for many years now and are in high demand as they consistently do a good job overall.

Banff is a tourist town in the picturesque Canadian Rocky mountains. The standard way to get there is via Calgary airport, catching the Banff airporter bus (one-way 2 hours, CAD54 with BIRS discount applied). BIRS itself is part of the larger Banff Centre, which is mainly an arts venue situated on a hill with elevated views over the town.

Food and Lodging:
Participants are all accommodated onsite in clean and comfortable single rooms sharing a bathroom with one other participant. There were some participants complaining about the temperature but I found no problems. The meals are also onsite in a buffet arrangement, and generally of a good quality (and hence tempting to pig out on the dessert). Internet access exists and works. I didn’t subject this to any serious stress tests.

Academic Facilities:
Here is a picture of Manish Patnaik giving his talk.

You can see the tiered seating (good) and the lack of blackboard space (bad). There was space from an architectural point of view to put in blackboards that can be moved up and down, so for a dedicated conference centre this is especially disappointing. All talks were recorded by an automated system (it is possible that not all were remembered to be recorded, as this process required manually pressing a button at the start of each talk).

Unfortunately some people continue to turn down lights during slide talks, despite the slides being perfectly visible under normal lighting conditions. This is annoying because it strains the eyes to make notes, and makes it harder to work on other things when (some) speakers inevitably power through their slides at too rapid a pace.

There are also other small private discussion rooms equipped with whiteboards for participants’ use.

Stephen D. Miller:
Stephen D. Miller was originally scheduled to attend and give a talk, but got screwed over by an airline and ended up deciding not to come. He then recorded a talk which we watched (and you can too (mp4)) and skyped in at the end of the viewing to answer questions. This worked surprisingly well, which I suspect is more a function of the speaker being Stephen as opposed to the format.

I overheard some other participants remark that they were still disappointed that Stephen didn’t come as they were hoping to discuss informally with him. Experienced conference-goers will naturally and immediately recognise this sentiment, knowing that the informal discussions that take place at a conference can be even more important than the formal program.

It is a little known fact that it is possible to spend a couple of additional days at BIRS afterwards. A few of us availed ourselves of this welcome opportunity.

My talk:
I did not give a talk at this conference. I did however give a talk on my recent work on geometric extension algebras at the University of Alberta the following week.

My 2016 Senate Election Vote

It is possible to check if your vote for the Senate was counted correctly in the 2016 Australian Federal election. To begin, go to this AEC website, download the Formal Preferences file for your relevant state or territory and unzip.

In my case, I download the Queensland file. The preferences I gave the first five candidates were 2, 1, 46, 47 and 20 so I type

grep 2,1,46,47,20 aec-senate-formalpreferences-20499-QLD.csv

and out comes

Griffith,South Brisbane,874,32,29,",,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,2,1,46,
109,48,49,32,33,34,60,61,114,115,116,117,118,119,18,4,120,121,58,59,24,25,26, 30,31,19,5,110,111,28,29,57,56,55,54,53,52,17,16,15,14,13,12,11,10,9,8,7,6,50,

The output begins with my electorate and polling place. I don’t know what the next three numbers mean. The numbers following the string of commas are my preferences, in order that the candidates appeared on the ballot paper.

Here is where it gets embarrassing. Eagle eyed readers will immediately have noticed that there is no 39 in this list, and there are two 82s. Nevertheless, I believe it is still formal.

Using the distribution of preferences from this other AEC site, it is possible to track my vote through the count. It passes through the hands of a few no-hopers before reaching Larissa Waters (Green) who is elected in 9th place.

Larissa Waters is elected at the 738th count with a surplus of only 181 votes. In theory my vote should then transfer at a paltry value of 181/209475 (about .0009) to Suzanne Grant (Xenophon team) but the vagaries of the inclusive Gregory system and the existence of loss by fraction makes it hard to say this with any certainty.
