In 1900 David Hilbert posed a series of 23 problems to the mathematical community.

These 23 questions have given the world of mathematics something to focus on for over a century. Some of the questions are still to be solved. Solving one pretty much guarantees that person a Field’s medal (Equivalent to a Nobel or a Pritzker prize). Architecture doesn’t have a set of key questions. This is a search to find some. A search to find if it’s even possible!

Starting tomorrow at about 4:30pm AEST we’re going to start tweeting questions. We’ll pull them all together with the hashtags #architecture and #bigquestions. Then the world can answer the ones that are answerable, and refine the unanswerable ones into that special set.

We’d love for other people to get involved. Just search for those hashtags and have a look at what’s already there. Then post some questions of your own. You don’t need to be an architect; everyone is affected by architecture so everyone gets to have an opinion and to ask questions.

In 115 years someone else might have the same conversation and start it with “In 2015 the world posed architecture’s 23 biggest questions”.
