The Australian arm of Mensa – the organisation for those with an unusually high IQ – held its annual Christmas get together in locations around the country this weekend.

Filled with chants, flags, and discussions about metaphysics, the gatherings were a chance for members to catch up and discuss their favourite equations.

“Often we feel like outsiders. So this is a wonderful opportunity to mingle with like-minded people, throw around some literature quotes maybe, or just count in prime numbers for a while,” member Dave Jenkins said. “They close off the streets for us as well, which is nice”.

Mr Jenkins can be seen in the picture above pointing out which chapter of Mensa the group is representing. “We have a bit of friendly rivalry with the other chapters,” he joked.

Fellow member Jack Short said the conversation at the Christmas functions can get quite heated. “Oh yes, there’s a lot of shouting. Get a couple of hundred fervent Einstein fans in the one place and there’s bound to be a bit of passionate debate!”
