Een inkijkje in het huishouden van Jan Steen én zijn veelzijdigheid

Zo’n dertig schilderijen van Jan Steen in de Leidse Lakenhal illustreren wel zijn artistieke veelzijdigheid maar niet veel van zijn persoonlijk leven.

"Of the many works of fiction that are published, very few involve mathematics or mathematicians. However, people who like mathematics (or are mathematicians ourselves) may especially enjoy reading those few that do. Moreover, as I argue in an article in the AMS Notices, mathematicians should be interested in these works of "mathematical fiction" even if we do not enjoy them because they both affect and reflect the non-mathematician's view of this subject." "At the moment, there are 1726 works of mathematical fiction listed in this database. This is much more than I expected when I started, and I have every reason to think that it will continue to grow as I learn of new works to list here."

The Mathematical Fiction Homepage is Alex Kasman's attempt to collect information about all significant references to mathematics in fiction. You can see the entire list (sorted by author, title or publication date). You can browse through the database to find your favorite genre, topic, motif or medium. If you've got more specific criteria in mind, try the search page. If you've been there before and just want to see what's been added recently, look at the listing of new/recently modified entries. For a more curated list, you can also check out Kasman's personal recommendations. Articles about mathematical fiction can be found on the resources page. The same page also makes note of other websites listing maths in the movies. There is some overlap between these sites and Kasman's database, but differences in criteria ensure they're not the same: The Mathematical Movie Database at QEDCat.com (With transcripts! Also a book) and their must-see list Oliver Knill's Mathematics in Movies page (With clips! And a 2006 povray gif?) Arnold G. Reinhold's The Math in the Movies page Brian Harbourne's Math Movie Picks Bonus: Wikipedia delves into the topic; so does TVTropes (pre-anti-adblock archive) (previously in 2009)

Old Stock Exchange Building

Old Stock Exchange Building

The Adelaide stock exchange building, between Grenfell and Pirie streets, Adelaide, brought an extra treasure with its opening in 1901.

George Brookman, one of the exchange members, had a stained glass window commissioned for it by William Morris’s famous London design company Morris & Co. in the United Kingdom. Artist John Henry Dearle’s six-panel window, Adelaide’s first by the Morris company, commemorated Australian federation. In its lower panes there are figures representing Britain and her colonies, including Australia, Canada, India and South Africa. In the upper panels. the figures represent the morning, the Sun and evening. The window survived fire damage to the building in 1938 and 1982.

Adelaide’s original stock exchange was formed in 1887 when a group of financial brokers and traders came together to trade stocks and bonds for companies listed in the colony. It aligned with the stock exchanges in Australia’s other capital cities in Sydney, Melbourne, Brisbane, Perth and Hobart. After outgrowing premises in Pirie Street, Adelaide city, architects H.E. Fuller and H.N. Dunn were selected to design the 1901 red brick building in the federation Edwardian style, with its distinctive corner tower, officially opened by South Australian premier John Jenkins.

The building hosted another important milestone when postmaster/astronomer general Charles Todd set up Australia’s first telegraph station there in 1901.

The stock exchange remained in the building until 1991 but it was left empty for the next 20 years.

In 2007, the South Australian government bought the building that was restored two years later for it to become a focus for the state’s science education when it was the first international satellite of the Royal Institute of Great Britain. During the renovations, spaces closed over the years were reopened and many original features restored, including many artefacts from the stock exchange's operations.

The federation window was donated to the Art Gallery of South Australia but it remained part of the building. The building was heritage listed at the national and state level.
