Cambridge Coincidences Collection

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Well I Never!

Professor David Spiegelhalter of Cambridge University wants to know about your coincidences!

Out for a run.

On Saturday morning's my friend and I take our dogs and go for a run. This morning I was a couple of minute late as I had picked up a book to look at. (We are book dealers and lots of books are stacked around.) The book was titled "Beyond Coincidence" by Martin Plimmer and Brian King. As I apologised to my friend for being late she said she was also late because she had stopped to listen to David Spiegelhalter on the radio talking about coincidence. "But" I said, "the book I was reading was on coincidence!"

Old friend

In 1987 I worked with a colleague in Saudi Arabia. When we came back to UK we forgot all about them. After some 17 years, my wife and I were wondering whatever happened to them. Few days later I received an e mail from him wondering whether I was the same guy who worked with him in saudia, as he had googled my name and found few matches! I wrote back to him saying ,both of us thinking about each other at the same time, was telepathy! Shiv B

Birthday Clock

20 years ago, on the morning of my 40th birthday, I came downstairs and went into my living room. The clock, which had been above my mantlepiece for many years, had fallen down in the night and smashed on the stone hearth. Later in the day, some friends called round and gave me a gift for my birthday. you guessed it, it was a clock, same model as the one which had smashed! I summed it up as follows: 1. To give a clock as a 40th birthday present to a single man was not unusual. 2. The clock was the same make and model. My friends had been to my house many times, would probably have seen my original clock, so may have known I liked that style. 3. The clock was shaped like a 50p piece with 8/10 sides, unusual, but was probably fairly common in the 1980's. (One of hundreds of possible styles). 4. If they had seen my original one, why buy me a second one which I wouldn't have needed? 5. The coincidence of giving me a clock on the same day that mine had broken! 6. When questioned, they said they hadn't really given the matter any particular thought, other than they had decided my present would be a clock. Phil.

Tesco and Sainsbury

I have noticed for some years that everytime the labour party is in Tescos do well, and Sainsbury do well with the conservative party . Is this coincidence, or otherwise?

Unlikely chains of events

I travelled to an oil refinery in Wales for a business appointment. There was an accident on the motorway which caused me to be an hour late for my meeting. When I arrived I was advised by the gateman that my contact had gone to lunch 10 minutes earlier. I asked him if there was somewhere local I could have lunch and he recommended a local pub. On walking back to my car a gentleman told me he had overheard my conversation with the gateman and didn't think the pub he suggested was very good and suggested I follow him to the pub he was going to. After we had ordered our lunch he commented that my accent suggested I was not from Wales. I told him I was from Scotland and he said that he was born in Edinburgh. I told him that I had an aunt who stayed in Edinburgh and that I stayed with her many times during the summer holidays. He asked me where she stayed and I told him her name and that her address was Hermitage Park in Leith. He then told me with astonishment in his voice that he stayed in the house, across the landing at the top of the stairs, from my aunt (their doors were 12 feet apart).

Old friends

I come from Southampton and now live in Nottingham, where I worked in a library before going into publishing. My son was in a pub in Bristol with friends. There was one seat next to him when a group of females came in. He got talking to the one who sat next to him. They are still going out together a few years later. She turned out the daughter of a friend I went to school with, hitch-hiked round France with when we were 16, went to the same university with, later shared a flat with in London for several years and had't been in contact with for c30 years. Just a few weeks after my son's first meeting, a old acquaintance rang me up out of the blue. I had helped him with information searching when he was doing his PhD in engineering in Nottingham in the 80s and I was a librarian. He had eventually moved into publishing, which was why he was contacting after all these years. It turned out that he lived a few houses away in the same road as my other new-found friend in Bristol...

Holiday Coincidence

Many years ago, following the death of my husband in 1988, I went on holiday with a friend to Guernsey, hoping to leave my decorator doing the hard work of transforming my house while I was away. Unfortunately, it transpired that he and his wife were also going to be away at that time (not much of a coincidence!). Off we went, ready to enoy ourselves and tackle the question of the decorating on our return (and the return of my decorator from wherever he and his wife had been holidaying). After enjoying the delights of the main island, we decided on a boat trip to the very much smaller island of Herm, looking forward to our day out. Having enjoyed this beautiful (and car-free) environment for a few hours, we reluctantly boarded the small boat that was to take us back to the main island. As I sat there with my friend, watching more people climb aboard and waiting for our departure, I was suddenly aware of what, to me, seemed to be almost an apparition. Climbing on to the boat were my decorator and his wife.

Stellar!

I have always had an interest in coincidences and have noticed them over much of my life - one day I was sitting in a downstairs conference room at work talking to some colleagues about this interest and explaining that in there is a whole galaxy (as in large and impressive collection) of examples when a lorry stopped outside the window bearing the name 'Galaxy Removals and Storage' - this really made an impression!

Two Mums

In 2007 my mother, who was then 87, had a hip replaced at our local hospital. When she went into a medical ward to recover I was putting her clothes in the cupboard by her bed. In the drawer I found a list of clothes headed with a name I recognised. This was my friend's mother-in-law whom I have never met but as her name is quite unusual I checked with my friend and her mother-in-law had been in the same bed immediately before my mother and had forgotten to remove the list of clothes she had taken in for her stay in hospital.

Iceland couch surfing

I had been back from a swing dance exchange in Iceland where, as everybody else, I had been hosted by one of the dancers, when I start talking with two american girls in a random pub in London. They tell me they are couch surfing around Europe and that they just came back from Iceland. They start describing their host, I recognize him to be my own, and I surprise them by saying "oh yeah, Jack" isn't he sweet ;-)
