Cambridge Coincidences Collection

As of the 23rd May 2022 this website is archived and will receive no further updates.

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.

Many of the animations were produced using Flash and will no longer work.

Well I Never!

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

Chance Encounter

I live in Australia. For five-and-a-half years I was in the worst relationship of my life with a person I would later learn, from various sources including specialists, was a borderline/narcissistic personality. By the end of it my sense of self had been almost completely destroyed, I had no confidence, everything had become a kind of relativistic miasma, my self-esteem was shot, I couldn't think about the future and barely had the energy to get through the day. I was at the end of my rope, not just because of the usual pains of a bad breakup, but because I had been leveled by degrees, by stealth, over the course of half a decade. The thing is, I didn't really understand that at the time. So the short story is this: a string of coincidences led me on a four-month international jag. I spent a little time in London. I met a friend at a pub, on a whim. We were drinking. I look up. And my ex's ex walks in the door. Now two things are important: 1). Over the course of my relationship this guy was held up to be a total demon, a black-hearted monster of the first order, and 2). we kinda knew each other before that relationship started.

Australian visit

Our son, who lives in the UK, decided to attend the Rugby World Cup competition in Sydney. He contacted his Godmother, who lives in Sydney, simply to say he would contact her at some stage during his visit. He sat down at one of the matches to discover that his Godmother was in the seat directly behind him.

How strange!

I have lived in various parts of the country over a forty year period and moved to my present address in Dorset 5 years ago. I signed on with a new doctor and on talking to the nurse at the 'introductory' medical found we had been born in exactly the same part of town in Portsmouth and later moved to exactly the same part of town at the north end of the island and attended the same school only fifteen years apart.

Of all the basilicas on all the mountains in all the world...

In October 2010 Bradford Cathedral Choir undertook a short tour of Catalonia, singing in and around Barcelona. My son and I have been singing in this choir for a few years and went on the tour. One of the events on the tour was to be a 15minute slot singing in the Basilica at Montserrat, where visiting choirs are permitted to do a short session at lunchtime on Mondays. We duly arrived at the top of the mountain and were waiting outside the Basilica to put our robes on and warm up our voices. Our choir director had been inside and came out to say we would be going on after "some choir from Nottingham, I've never heard of them". At hearing this, I got a funny feeling and thought "I need to see this choir" as I used to live and sing in Nottingham for several years before moving to Yorkshire. I went in and sat quietly to one side of the church and listened to my old friends the Sinfonia Chorale, of whom I was a member for 10 years previously!

Mr Michael D

I was born and grew up in a small town in Oxfordshire in 1970. I moved to London and became a doctor and one of my good friends from home moved to London and became a lawyer. He became a partner in a London law firm in 2008. In 2010 I became a Consultant Orthopaedic Surgeon in Hastings in East Sussex. The secretary I was given had lived in Hastings for many years but this was her first secretarial job. One day I was talking to my friend on the phone and my secretary asked what he did. I told her and it turned out her sister worked for the same firm as she was a legal secretary in London. A few phone calls later revealed my secretary's sister was my friends secretary!

Flight neighbour

It was about 1995; I was about 55 at the time. I was on a family-related trip to Aus (NSW), decided to go up to Queensland (Airlie Beach) for some SCUBA on the Barrier Reef. Signed on to a 3-day boat trip, with about 10 others, all of them total strangers in their 20s or so, origins from all over the world. Amongst them was Roger from (I think) Amsterdam who turned out to be a real Pain in the A**. About 2 weeks later, time to return to UK, flight from Sydney to Bangkok for a 2-day lay-over, back to Bangkok airport for the BA Jumbo flight to London, boarded, sat down, next seat-but-one to my left is Roger! (To be fair, I had spotted [and avoided!] him earlier, waiting in the airport lounge, so the coincidence maybe isn't that huge?)

a musical coincidence

In the spring of 1985 I was at an exhibition at the National Portrait Gallery, London, marking the 300th anniversary of the birth of Handel. The exhibition contained several portraits and a number of music scores. Not unnaturally there was some background music going on as one walked round it. At the time I was visiting, the music was the composer's Music for the Royal Fireworks. And on a music stand was the original manuscript of... the Musc for the Royal Fireworks. As I approached the exhibit I noticed it was open at the movement called La Rejouissance. And the music playing was... La Rejouissance. So I was able to follow the original manuscript with my eyes and the music on 'original instruments with my ears at the same time. What were the chances of that happening?

Repeating words.

My wife and I are continually surprised when talking , how many times odd words are repeated instantly by the radio or television.

Lady Crossing the road

I stopped to let an elderly lady cross the zebra crossing. My heart missed a beat as the car on the other side did not look as it was going to stop. The lady was so busy waiving to me that she did not notice this. For a split second I thought she would be hit but the other car did stop, leaving us both very shocked. A few weeks later I was about to cross on a zebra crossing in a nearby town - I observed to the elderly lady standing next to me that I prefer to wait until both sets of cars have stopped before I cross and I briefly alluded to the above incident - That lady was me she said - and as we compared notes it was clearly her!

Advance meeting

One day I was travelling from Lewisham in SE London to South Ealing in W London to visit a friend. I changed from the Northern Line on to the Piccadilly Line at Leicester Square Station. As I got on the Piccadilly Line train I noticed that the carriage was full, apart from two empty seats next to each other in the middle of the train. I approached the nearest seat from my end of the carriage; meanwhile, someone else sat in the other seat. The other person was the person I was on my way to visit.
