Winter Weekend

We very much regret to announce that in view of the coronavirus, the 40th M500 Society winter Weekend will not be held in 2021.  We anticipate holding it in January 2022, and will update this page as appropriate.

The 39th M500 Society Winter Weekend was held at Kents Hill Park, Milton Keynes from Friday 10th to Sunday 12th January 2020.

People attending for the first time received up to £25 discount by solving Dorothy’s sweets puzzle.

Also, groups of new people attending for the first time received a group discount. 2 new attendees booking together get a £50 discount (£25 each), a group of 3 £100 and a group of 4 £200.

The Weekend provides an opportunity to do some recreational mathematics, not module-based, with a friendly group of like-minded people. The relaxed and social approach delivers maths for fun.  The following sessions were included:

  1. The regular quiz on Saturday which will have a mildly mathematical flavour.
  2. Code breaking and Infinity. A session by our visiting speaker Dr Katie Chicot.
  3. Distance measures and different metric spaces by John Hoskinson.
  4. Mathematical Magic with Angela Allsopp and Paul Cooper.

The Weekend is based on a number of worksheets relevant to the theme, and participants can choose which problems to pursue. Mostly we work in small groups, but you can choose who you work with—nothing is compulsory! It should be approachable to anyone who has completed MST124/MST125, but there will also be material to stretch those who feel the need.

In general, we start with dinner at 7 pm on Friday (arrive any time after 2pm) and finish around 4 pm on Sunday. You don’t have to be a member of M500 to come to the Weekend, but if you are, there is a small discount (see below). If you decide to join at the same time as coming to the Weekend, please make sure that you send the membership form (and membership fee) to the New Membership Secretary, not to the Winter Weekend Organizer.

The Weekend price was £220 for M500 members and £225 for non-members. This includes accommodation and all meals from dinner on Friday to lunch on Sunday.  For shared accommodation please e-mail the Winter Weekend Organizer at  The day rate, including lunch on both days, was £102.

If you haven’t been to a Winter Weekend before, and don’t know what it’s about, read Information on the Winter Weekend (PDF), read a personal review of the 2011 weekend or have a look at a sample of the material from previous Weekends.

All being well, bookings will open in the autumn 2021.
