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!

birthday coincidence

My sister's birthday is 18/7, her husband's is 18/3, their oldest child's is 18/5,

Hearing a song

This happened in approx the year 2000. One evening, a friend and I were trying, unsuccessfully, to remember the theme tune to the 1980s TV series "Tales of the Unexpected" (by Roald Dahl). The next day, I was walking down the road and a busker was playing the theme tune on his harmonica! Doubly bizarre wouldn't you say?!

Damascus Steel

I was reading one of Emerson's essays (forget which one as it was about 30 years ago) and had the radio on low volume in the background (either radio 3 or 4). As I was reading I came upon the words Damascus Steel (unfamiliar to me at the time) and as I read those words my ears pricked up as the same two words were spoken on the radio program, enunciated no more than a second after I'd read them.

Mother and Daughter on a Journey

This happened in 1996. I was on a photography course in Banbury, and lived 3 miles outside the town. My daughter was living just outside Chesterfield in Yorkshire. I was set a project called 'The Journey' and had to produce a number of photographs depicting a journey of my choice. I decided to record my grocery shopping trip. This involved me taking a bus from the village into Banbury, then another bus to Tesco. This was a trip of approximately an hour and a half because I was stopping to take photographs at various places. I took photographs at the bus stop, on the bus, in the bus station, the bus driver and passengers, and people walking along the road. I got to Tesco and my last photograph was to be of the main door with all its great reflections. I looked through the viewfinder of my camera and my daughter was standing in front of the main door, waving at me. On the spur of the moment she had decided to visit friends and had driven down the M1 and then the M40 from Chesterfield. She still had quite a long way to go and feeling hungry she took a detour off the M40 to Banbury Retail Park to buy a sandwich from Tesco.

Odd and even birthdays

I have a wife and three children. Nothing unusal there. The day, month and year of my birthday are all even numbers; and the same is true of my wife's birthday. And my children - they all have odd birth days, birth months and birth years.

Expelair

I am about to visit the loo when an unexpected parcel drops through the front door. I open it and it is a present of poet Douglas Dunn's 'The Year's Afternoon'. I take the book into the downstairs loo with me but the extractor fan there is noisy and does not go with poetry. So I migrate to the bathroom upstairs,. I sit down, open the book at random and read: 'The Expelair in the lavatory - Relentless thing - is a better orator Than I would want to be'

Geoffrey Briggs

A few years ago my wife, her sister and I were travelling in a car on Interstate 5 north from Seattle (where my sister in law lives). For some reason we were talking about social security in the USA which then became a general discussion about social security systems in the world. I remarked that I had once heard that one of the earliest social security systems was in Uruguay. A second or two later a car passed us and, would you believe, the number plate of the car was Uruguay. In the USA of course you can have anything you like on a number plate provided it isn't obscene etc. We were flabbergasted.

Nominative determinism

The following text comes from an email which I sent to a friend on 28 April 2013: "Thank you for extending this discussion* into the fruitful field of nominative determinism - which of course explains my commitment to Freedom of Information and my confident expectation of being appointed the next head of the Information Commissioner's Office. To my delight and surprize, the subject was raised substantively on 24 April in the Royal Courts of Justice during the Judicial Review of the Chagos Marine Protected Area (MPA). That was the day for arguing points of EU law and Maya Lester QC, appearing for Olivier Bancoult, tickled the largest unprotected nerve in their Lordships' bodies [always a good move in court, sometimes even leading to a victorious debarquement on the Mornington Crescent quayside] by telling them that by a happy coincidence she had just discovered the previous evening that the head of one of a key body regulating the French fisheries industry was a certain "M.

The Doc Watson

In a cafe in Edinburgh I hear music which I like so much I ask the waitress what it is, She tells me it's Doc Watson's 'Memories'. The next day a package drops through my letter box. It's Doc Watson's 'Memories', sent to me from North Carolina by a friend who is temporarily working over there and has been to a Watson concert,

Chilli Farm Cottage

A couple of years ago, I sold a PC game on eBay, and when I went to send it, I wrote the name and address of the buyer that eBay told me on the envelope and posted it. I remembered the address, because it was 'Chilli Farm Cottage'. At the time, I was working as a consultant at DVLA in Swansea. The next day, I was watching someone type in batches of vehicle tax changes of address. Each batch contained 100 names and addresses. In the middle of the batch, up on the screen came the same name and address - 'Chilli Farm Cottage'! What are the chances of that? It may help to knew that there are 34 million registered vehicles in the UK.
