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!

A photo and the real thing

When I became a Roman Catholic in London in 1973, my sponsor,a Sacred Heart nun called Sister Mary Gutridge, gave me a photograph of a crucifix that had been made by her brother-in-law, sculptor Philip Lindsay-Clark. I put the photo away and more-or-less forgot about it. Some 19 years later I returned to the UK, having lived overseas with my family for some years. We decided to settle in Chichester, but, sadly, my husband had a fatal accident on our return. While he was dying in hospital I went along to the local Catholic church, which I did not know, and was struck immediately by the familiar appearance of the crucifix hanging over the door. I made enquiries and discovered that it was indeed by Philip Lindsey-Clark. Back home I dug out the picture I'd been given so long before - on the back was the location of the original , St Richard's Catholic Church, Chichester. I have always been struck by the strength of this coincidence.

Birthday numbers coincidence

Twelve people in a room on a course. Briefly asked to form into six pairs. One woman suddenly leaves and goes home, leaving me stranded. I'm paired with someone else while facilitator takes on the spare person. Then we're asked to find out the birthdate of our paired person. Mine is 17.1.1936. Hers is 17.1.1963. Each set of numbers add up to 10. Unlikely but true.

LONG LOST FRIEND

In the late 1960's I was working as a young trainee stockbroker in the City. One day I wandered over to a colleague's office to suggest we went to lunch together. He was talking on the telephone to a client about Marks & Spencer shares. When he finished he casually remarked that his mother had worked in the Chairman's office of M&S. I told him that my mother had worked in the Managing Director's office as well. Not expecting any positive result we swapped our mothers maiden names. When I got home I asked my mother whether she ever knew somebody called Valerie ....... when she worked for M&S. My mother told me that Valerie had been her bridesmaid and a good friend with whom she had lost touch. After my father had died in 1958 she had tried to contact Valerie but she had married, moved away and she could find no trace of her, although she had tried on a number of occasions over the intervening years. As a result of a chance remark by a colleague of mine my mother was able to contact Valerie and, as far as I am aware, they remained in contact until my mother died a few years ago.

Bumping into strangers twice in 4 days in different parts of the country.

I work in a school in Gloucestershire and on the last day of the summer term 2011, I accidentally left my raincoat behind, which meant I didn't have it when we went down to Cornwall two days later for a week's holiday. Fortunately, the weather was good so I didn't need my raincoat. On the Thursday of our holiday we visited the St Austell brewery and my husband and son went on the guided tour while I waited in the bar area and had a cup of coffee. While I was waiting, the next group of people for a guided tour started arriving and waiting in the bar area. I enjoy watching people and I noticed two women, one in her 60s and the other in her 30s. They resembled each other so I assumed they were mother and daughter. We returned home to Gloucesteshire on the Saturday and on the Monday I drove to Cheltenham to go shopping. However, on the way I stopped off at school to pick up the coat I had left behind and stopped to chat to a couple of colleagues who were working. (You were wondering what the raincoat had to do with it!) This meant that my journey to Cheltenham took about 15 minutes longer than it would normally take.

Crossing continents to the same street, same house.

A young girl leaves her village in Somerset to spend a 6 month working holiday in South Africa. Once there she immediately meets a South African and they are married within 6 months. They set up home together and buy a house. Meanwhile back in the Somerset village the Church Jumble sale collection is underway. The mother of the girl who left the vllage has a box of jumble to donate. There is a knock on the door.

birthday coincidence

I have taught Chemistry at the same school for 30 years. When I was appointed, my Head of Department (now deceased) had the same birthday. His DoB was 23/5/48 and mine is 23/5/58. He had graduated from the same University having done the same course (Chemistry) 10 years ahead of me.

Visit from Missionaries

I live in a particularly remote part of Lithuania. On Saturday January 14th 2012 I was sitting in my flat listening to BBC radio on the internet. I heard Prof. Spieglehalter's interview about this survey. An hour later I listened to a recording of the previous day's 'News Quiz', and I was enjoying the story about U.S. Republican presidential candidate Mit Romney's time as a Mormon missionary in France. The doorbell rang - this happens perhaps once a month as there are very few people I know out here, and all of those people were at work. Imagine my surprise to find that my visitor was in fact a Mormon missionary! Now I know that back in the UK I see one of these characters perhaps every other year - and I never expected there to be an active mission deep in Orthodox Lithuania, only 5km from the Byelorussian border. But how strange a coincidence for me to be in the flat, having a visitor who happened to be a Mormon AND a missionary at the same time as I am listening to a story broadcast 15000 km away about....Mormon missionaries!

Pete B

In my 30's, I was studying for an M. Ed. degree In Cardiff Uni and was soon travelling every week with a guy who lived some 5 miles away and who was studying on the same course. We became close friends. We both arranged our summer holidays at the same time (January 1980), he was going to Florida, I was taking my family to Athens. Days before we were both due to travel, independently and without knowing each other's circumstances, we were both let down at the last minute by our tour operators and told our holidays were cancelled. We hastily re-arranged our holidays with other, different holiday providers and again, neither party knew of these arrangements. I was taking a swim early one morning off an isolated beach in the tiny Crete resort of Elunda; I'd swum out for 20 minutes and returned, keeping my head under water at the last until my body was grounded on the sand. Putting up my head, I noticed a pair of feet in front of me. It was my friend, standing, looking out to sea, who hadn't recognised me! He too was staying in Elunda. How co-incidental was that!

Jolly Boating

In 1980 I was a PhD researcher in the Energy Research Group at the University of Surrey in Guildford. Mick Patterson, my colleague was in the next office-22BC03 to my 23BC03. He lived in Godalming, and I lived a few miles further South so occasionally I would pickhim up on the way to work. Godalming is upstream of Guildford on the River Wey, that enters the Thames at Weybridge. I rowed and coached the University Boat Club (which I still do) and Mick was an active member of the University Sub Aqua club. During the Summer I sculled in the evenings from Guilford Rowing Club. The course is short compared with our then normal training location at Walton on Thames. There is about 1KM of relatively straight river at Guildford to the 'Red Door' and then for safety reasons you have to go around a couple of bends and turn just below St Catherines Abbey ruins. One Thursday evening I was doing some pieces and resting at the turninig point. I noticed that the river was full of rubbish-papers , envelopes etc. A small brown package, banged against the side of the scull and started to sink. So I grabbed it and threw it into the bottom of the boat.

Captain Robin M

Many years ago, during a quiet time operating a flight between Singapore and Sydney, a passenger asked to visit the flight deck. I put aside a letter I was just composing to the commitee of a small village in Hampshire of about 1000 people to where I had just moved, asking for membership of the cricket club. The gentleman arrived on the flight deck ( in the good old days before 9/11) and during the ensuing conversation it transpired that not only did he come from Ropley (the village in question) but he was also the Chairman of the cricket club. I handed him my letter in person. Job done.
