I can’t have been the only one who was delighted when Barack Obama outed himself as a Trekkie while on the campaign trail last year, flashing Leonard Nimoy the Vulcan salute and assuring a Wyoming audience that despite his criticism of the bloated Nasa budget, the space programme was important to him: ‘I grew up on Star Trek. I believe in the final frontier,’ he told them. My president's a geek. More than that, Star Trek is a celebration of curiosity and self-improvement – and not a little socialist. Money has been abolished by the 24th century: ‘The acquisition of wealth is no longer the driving force in our lives. We work to better ourselves and the rest of humanity,’ says Captain Picard. But an old piece in the LRB by Tom Shippey says that I have it wrong.

One of my wisdom teeth is coming in, and my dentist is on holiday. It’s my own fault: he’d warned me to have them taken out, and I hadn’t listened. On Monday, while waiting until I could take the next ibuprofen, I emailed intelligentdesign.org: ‘How do you account for wisdom teeth?’ The blessings of suffering?

I looked for mentions of wisdom teeth in fiction. Up came the novels of Ian McEwan: a wisdom tooth extraction provides a suspected criminal with an alibi in Saturday, and in On Chesil Beach, when the boy kisses the girl, ‘he probed the fleshy floor of her mouth, then moved around inside the teeth of her lower jaw to the empty place where three years ago a wisdom tooth had crookedly grown until removed under general anaesthesia.’

Only question asked by immigration official at LAX: 'Did you enjoy having Dennis Quaid on your flight?'

Auctions are often plagued by something called the winner’s curse. The person who ‘wins’ the painting or Floridian land parcel usually pays too much for it. Unless the winner knows something that the other bidders don’t, he's probably overvalued the object: otherwise, why wouldn’t someone else in the room be willing to pay as much? But the online charity auctions run by raffle.it are in a format I hadn't encountered before – they seemed, possibly, curse free. Each of their auctions is like a regular raffle, except you get to choose your own number (only positive integers are allowed). The winner is whoever has the lowest unique number: if Anne has 2, Betty has 3, Cindy has 2 and Diana has 7, then Betty wins. Once you've chosen your number, you're told whether or not someone else has already gone for it.
