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!

Sisters think alike

I am 52 and live in Edinburgh. My 2 younger sisters (49 and 47) live in the Midlands and Essex. We haven't spent a Christmas together in 15 years and see each other on average about once a year. For Christmas 2010, we each bought each other the exact same Marks and Spencer necklace. I bought one for the middle sister, she gave one to the youngest and my youngest sister gave one to me.

An amazing chance meeting

My wife and I were taking a flight to Canada to attend a friend's (Mike L) 50th birthday party. We hate flying and were dreading sitting for 6 hours with people we didn't know. The couple who eventually sat next to us thankfully spoke little until we were about an hour from Toronto, when the usual banter started - "Have you been to Canada before?" - The two ladies chatted away until her eyes glazed over slightly, she conferred with her husband, and then turned to my wife and said "Are you by any chance going to "Mike L's birthday party?". How about that! Two couples, both going to the same party, one couple living in the UK, one couple travelling in the UK, but from Canada. We were both on our way to the same party - only 100 people or so. And both find ourselves on the same flight and sitting together! We have since become great friends!

Two people meet on the train and start talking about me

Two people I know, who did not know each other, in Sweden (where people do not usually engage in conversation on trains), not only started to talk on a train trip between Malmo and Göteborg but discovered that they had a friend in common, me.

My landlady

I was living near York attending college and 2 Australian girls I knew were on holiday, got my landlady's tel no from my mother and rang her. She said I was at college and would be home at 16:30, but left them the address. She then went to York shopping. When she returned and when I got home, she said she was approached in York by a young lady who asked her if she knew how to get to the village and house in which she was resident. My landlady asked if she was one of the girls who had phoned her earlier. Of course it was. Now York's a pretty big place, so the odds on asking my landlady are? Well, go figure.

Coincidental meetings

A work colleague and I were on a study trip to Japan and Australia. We had spent 10 days in Japan then flew, via Hong Kong, to Sydney. Having retrieved our baggage, we were waiting in the taxirank queue when someone said, "I thought I recognised the voices". Immediately behind us was a member of my companion's staff, who had flown into Sydney, for a holiday, coming from London by a completely different route. We were flying from Gatwick, to Turkey, for a holiday on a Turkish gulet. Standing in the check-in queue, my wife fell into conversation with a woman standing next to us. It turned out that she and her husband lived in Marlow, where my wife had lived for 30 years, until our marriage 2 years before. As the queue advanced, we arrived at the same check-in desk as the other couple, with the two women still chatting and getting on well. They were booked on the same flight as us, a general charter, being used by a number of holiday tour companies. Arriving at Dalaman, we were directed by our gulet cruise rep. to a very small bus, which would take us to the boat, at Marmaris.

Lancaster Bomber

In 2005 while working in the Auchterarder Tourist Office a gentleman came in asking for information about the Lancaster Bomber which had once been part of an aircraft collection at the Strathallan Aircraft Museum. The Museum had been closed for over twenty years but we were continually asked about it. I told the gentleman that there had been a Lancaster Bomber at the Museum but thought it had been moved to England when all the planes were dispersed. He was amazed to learn that it had been in the collection as he thought it must have been very difficult to get such a large plane to land on a small airstrip (now a parachute club uses it) He had only been gone a few minutes when another gentleman came in to the office and we got chatting about various things. I told him that I had just been chatting about a Lancaster Bomber that had been flown in to Strathallan and he started laughing. Turns out he was one of the crew who brought the Lancaster back from Canada to Strathallan!! Quite a hairy journey by all accounts but I was so annoyed that he had not come in to my office 5 minutes earlier.

Family birthdays

All four children born on the same day of the week (Tuesday); coincidence 343 to 1 ? which is also the birthday of the father; coincidence 2401 to 1 - I think!

meeting in the tower

In the summer of 1989 I got a new job working for the WEA (Workers' Educational Association) as a Tutor Organiser. The departing Tutor Organiser was part of the interview panel and I already knew him a little through my old job. That summer I went with my husband and children to the Dordogne in France on holiday and we decided to explore a castle in one of the towns. As we climbed the medieval spiral stone steps of one of the towers we met the Tutor Organiser and his wife coming down and we met in the middle. We were rather loud in our greetings and sharing the hilarity of the meeting and were asked to leave the tower! We went and had ice creams in the grounds. Neither of us had shared holiday plans and so it felt like a total coincidence. The other thing I found out in that conversation - which is less of a coincidence but struck me at the time - was that at that time he was the only person of my acquaintance who had watched every episode of Twin Peaks which had recently shown.

April Foolish

My wife was the first-born girl in the family on April 1st. 1934, on Anglesey, Wales, and appropriately named Avril. Her first-born girl was born on April 1st. 1960 in N. Nigeria, named Joanne Elizabeth. Her first-born girl was born on April 1st. 1987 in Cambridge named Alice Georgie. All were normal deliveries. Graham.

It's a Small World

I meet my now husband through a dating agency as we both lived in the West Midlands a huge conurbation. When my mother- in- law was showing our wedding photographs to my husband's cousins, one of them recognised my best friend and maid of honour. They had shared a house together in Hull when they were students at University. My sister met her husband in London - another huge conurbation. It later transpired that my father-in-law was at the same school - three years apart- from my sister's father-in-law and there is a whole school photograph showing them together.
