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!

the menu in An Amazing Meeting

Some years ago my wife and I were returning from a holiday on the Isle of Wight. We caught an earlier ferry than the one that had been prebooked, and on the return journey to Cheshire, we stopped at a public house for a quick meal. However, the menu available was not to our liking so we left immediately to find another place to eat. As we were approaching the Bristol area (not on the motorway), my wife mentioned that she wished to visit a toilet and remarked that if she knew the location of the parents of our son's girlfriend, (who we knew lived in the Bristol area, but no idea where) we could visit them to use their toilet. Within minutes we were approaching a roundabout when I noticed that the car exactly in front of us was our son's. His girlfriend (who was the passenger) simultaneously stated to my son that the car behind was just like his parents, and when he looked in the mirror, he confirmed that they were his parents. So we followed them back to the girlfriend's parents house which was within a quarter of a mile of the roundabout, and my wife was relieved!! What a coincidence on timing and location.

EARLIER OCCUPANTS

In 1987 my wife and I purchased a small property in a very Spanish village - Guardamar del Segura - from an English couple who introduced us to some English ex-pat friends living about 7 kilometres away in Torrevieja. Around about 1995 my wife called me from the garden telling me that my cousin's husband was on the telephone. As, sadly, we did not have regular contact apart from Christmas cards I suspected the worst and told him so. He told me not to worry, he was only ringing to tell me he had been to our Spanish property though we had never told them of the purchase. He explained that they had gone to Torrevieja and in conversation with ex-pat friends they were told that Maria had sold her bungalow to someone named Harrington. At this my cousin Betty laughed and said "Not Les Harrington" which they confirmed. Apparently they had visited Maria some years before we purchased and the Torrevieja friends were those to whom Maria had introduced us.

Workplace Family Tree Discovery

I work as a civil servant. A couple of years ago I joined a new department and bumped into another chap (Tim) who shares my surname. We chatted for a while and it came out that we are both interested in family history and had started compiling our respective trees. His family was from south west Devon and mine from north west Devon. Its took a few months searching and travelling around before it became apparent that we have an ancestor in common who was born in NW Devon in 1710. We are 7th cousins; not once, twice or thrice removed, just exact 7th cousins. The two lines diverged in the 1760s and as far as we are aware had no contact until Tim and I bumped into each other. Genetic testing has confirmed the link on the paternal line. What are the odds that two people start at the same department at the same time with the same surname and are exactly related?

Waiting for a Ferry

My husband and daughter (we live in the suburbs bordering Kent and London), were going to France for a couple of days. Whilst waiting in the queue of cars waiting to drive onto the ferry at portsmouth, my husband was looking into the car next to him in disbelief. His cousin (who lives in Lancashire), was in the car alonsgside my husband with his wife and 2 children. They ended up getting the ferry together and having fun in France until my husbands cousin, continued his journey to Belgium.

R Duffy

This is the coincidence of a friend: Between April 1985 and 1986, an Irish friend of mine, living in Manchester (had been there for over 10 years) had a year off to work and travel - along with her sister - in Australia. For the first 6 months they worked - in either Sydney or Melbourne - I can check - then for the final 6 months they travelled extensively throughout the continent, hitchhiking mostly, but also taking other means of transport. One Friday afternoon they were dropped off by a lorry driver at some small town in the Outback - in a really out of the way place - near Darwin (but not too near) or maybe Alice Springs. These are 2 hardy women who grew up on a farm in County Sligo. They planned the journey to some extent, in order to keep in touch by letter with their parents ( they were 27 and 25) and so they knew that in 2 week's time they would be picking up a letter at some town along their route. They checked into a small hotel and headed upstairs to wash and change. As they climbed the stairs, my friend said to her sister "That fella at the bar" - she could see an older man sitting having a drink - "he's Irish".

The tube in her rucksack

In December 2011 I had a holiday on Iona and was travelling across Mull on my way home to Banchory, in Aberdeenshire. It was 6am and the bus picked up four passengers on the way to the ferry terminal. One woman in her early 70s carried a haversack containing a long tube which stuck out from the top. There is a two hour wait in Oban for the train to Glasgow. I bumped into the woman in Oban and asked her if she would join me for a cup of coffee. She had spent her childhood in Inkpen, the same village in Wiltshire as my husband. She knew his parents well and many other mutual friends. Her son had been taught by my husband's mother. She had first set eyes on a double bass in my husband's uncle's house. He played a few notes for her. She knew then that she wanted to learn the double-bass; but she became a stage-manager. She and her husband retired to Mull and he died in his seventies. She spoke to friends about her childhood desire to learn the double-bass. They encouraged her. The new head of music in Oban Academy is a double bass player. She now practices every day for 2-3 hours and plays in three orchestras. The tube in her rucksack contained her bow.

Myself and my two sisters all had our first born children on New Year Eve.

technical support

When I first started my Ph.D. I was working with a then new operating system along with another student and we were having some problems. One evening I stayed in the office to work on a problem after my colleague had gone home. After a few hours I wanted to ask my colleague a question so called his flat. Oddly, the phone didn't even ring before my colleague picked up. We started talking over the problem before it because clear that we were talking at very slightly crossed purposes. It transpired that he'd had a flash of inspiration whilst at home and had called me to tell me his thoughts... at exactly the same moment as I'd called him to discuss the same subject. We both dialed the other number, were connected and assumed we'd placed the call.

Family Reunion

We are from North Shropshire and were on our "once in a lifetime world tour" and reached Rotorua in North Island New Zealand for a one night stopover. We checked in to our hotel and as it was my husband's birthday we arranged to eat early in the hotel restaurant so that we could go out and do as much sightseeing as possible. The booking was in my name ( I have maintained my maiden name Thorley ) so when we walked in to the hotel restaurant the waitress saw my name and suggested that she added our meal bill to the "group booking" bill. We explained that we were not part of a group and had booked independently.

Co-ann-cidence (ho ho ho, how we laughed)

I was talking to my wife about a friend (Ann) who we had not seen for some time. Later, I was with an acquaintance (Betty) who mentioned her brother and his wife (Carol) and showed me a photo of them Carol looks like our friend Ann Carol’s a tax inspector. So is Ann Carol works in Portsmouth. So does Ann (For the sake of clarity: Carol is not Ann)
