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!

Reunited from maternity ward

(I've changed the specific names, but the story is, I believe, accurate). My mother was born in Scotland, in the next bed to a Jane Smith. Their mothers became friends, and the children played together growing up, since they happened to live nearby, until the Smiths moved to England when the girls were about four. My mother did a BA in Scotland, but a PhD at Elided College, Cambridge. Years later at an Elided reunion, she met someone who turned out to be Jane Smith, who had done her BA there - obviously, they'd not quite overlapped while actually attending. That would be a slight coincidence, but it turns out that my father, who also went to Cambridge, had one ex-girlfriend before meeting my mother... Jane Smith.

Travel/key coincidence

Having just posted Travel Coincidences and including a coincidence involving a key (below) - I have just remembered another: While in South America, I was travelling with an overland truck and each passenger had a key to the padlock for the truck door. In El Chalten in Argentina, I lost my key. 4,500 miles further north, we stayed the night in a dormitory room near Uyuni in Bolivia. Hanging on the curtain rail I found a padlock key, which fitted our padlock. This had obviously been left and forgotten by a previous passenger using the same overland travel company, but still, it was amazing that it was me who found the key.

Travel coincidences

Almost all my coincidences are around travel: In 1988 I went to Berlin and bumped into a departmental field trip from my university, including many people that I knew. In 1990 I crossed paths with a woman while I was travelling in Finland. I had met her four years earlier when I spent some time on the kibbutz near Jerusalem, where she had previously lived for 20 years. In 2005 I was stuck at the ferry port in Turkmenbashi and chatted briefly to a Japanese girl there. Two months later I found her in a youth hostel in Warsaw. In 2006 I travelled for some time, from Ushuaia to Cusco, with a woman and a couple. Two months later I bumped into the woman in Lima and a month after that, the couple in Ciudad Bolivar. In 2008 I travelled in Mali and discovered our British driver used to perform in a travelling theatre group based in the north west of England, for which my Dad did props and cooking. On the same trip in Mali, I met a couple from Brighton.

Multiple similarities

Some four or five years ago, I taught a student at the University of Sheffield taking a part-time degree who shared my first name (Peter), was left-handed like me, and had a daughter called Eleanor as I do. The really coincidental thing, however, was that we had each lived as a child in the same road (Iron Mill Lane) in Crayford, Kent. I cannot now remember how I discovered this last detail, and if I remember correctly we had not overlapped in time and had attended different primary schools. I believe that he is still around in Sheffield, graduated in the last year or so, but I have not run across him recently. Simply writing this out makes me doubt my memory because it seems so unlikely but I think I have recalled the details correctly, and it might be possible to check if thought important.

Island encounters

My wife and I spent a fortnight's holiday on the Italian island of Ischia in the Gulf of Naples in May 2008. Less than a month later we spent a week on Mainland Orkney. One very rainy afternoon we were in Kirkwall, about to drive away from a car park, my wife spotted someone getting out of a nearby car. Despite the rain and hooded anorak she was convinced that she recognised her as the lady who had sat at a neghbouring table in the dining room at our Ischian hotel. I was sceptical but decided it was too good an opportunity to miss so asked whether she had stayed at the Villa Durrueli a fortnight earlier. She confirmed that she had indeed been there, and remembered speaking to us. Following a brief chat we went our separate ways, not quite believing what had just happened.

Eton PM Question

My question (sorry) is about the coincidence of Eton old boys becoming Prime Minister (19 thus far) what chance of someone born in social housing (15%? of us) becoming PM versus someone who's been to Eton(0.0001%)? Many thanks

Holiday coincidence

In the 1970s I booked on a music-making holiday. At the time I was a trainee paediatrician in Sheffield. Also on the holiday was a trainee obstetrician from Sheffield who I knew slightly. "What a coincidence" we said. My next holiday was cross-country skiing in Norway. You can guess who was also on that holiday. I then moved to Liverpool and a couple of years later met a lovely chap from Staffordshire who worked for British Coal. We duly married and, there being no collieries in Liverpool, I moved to Staffordshire and took up a post at Burton on Trent. And you can bet who was by now a consultant obstetrician at Burton.

Hot bedding

In 1985 I spent a week scuba diving in the Isles of Scilly. I and my dive buddy stayed in a B&B in Hugh Town, St. Mary's. Two weeks later my buddy was on a family holiday on the Llyn Penninsular in North Wales. He was walking on Porth Neigwl beach and, being a London cabby, struck up a conversation with a dog walker, the only other person on the beach at the time. The stranger commented that North Wales was a contrast with his previous week's location. To cut a long conversation short, it transpired that he had just returned from a week's diving in Scilly. He had not only stayed in the same B&B, but had slept in the bed vacated by my buddy. He had arrived on the "Scillonian III" which docked at lunchtime. We then boarded the same ferry for our return trip home. Our paths must have crossed on the quayside.

The Birth of Adam Smith

Our first child was born at St Mary's Hospital, Paddington, on 30th November 1970. For no particular reason, other than we liked the name, we called him Adam (Smith). Over the next month or so, I came across an article or a book review about the 18th century economist and philosopher, Adam Smith. Although I knew about him, I knew very little detail about his economic theory or philosophical ideas, and decided that under the circumstances, perhaps I should familiarise myself with his work. I was a member of Marylebone Library at the time (convenient, working at St Mary's Hospital), and I guess some time in December 1970 or early in 1971, I took out a copy of "The Wealth of Nations". It was a fairly new Penguin edition, the cover of which had been laminated. It had been taken out by one previous reader - on 30th November 1970! - a coincidence which has amused us, Adam and our friends over the years. I was reminded of it while listening to your session on "The Life Scientific" last week.

slobbery dracula

Our dog an enthusiastic eater, had just finished his food - he was covered in slobber with his canine teeth showing. I remarked that he looked liker a 'slobbering Dracula'. At that VERY moment, I got an order for a Vampire book (for sale on my website), from someone who in all honesty (I still have the proof of posting certificate), was called Slobadon Draculic. john o'donnell Bristol Books Bristol
