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!

Mountain meeting

This is one of many. I drove 150 miles with friends and was walking on top of a mountain in the Peaks, and coming towards me was one of my neighbours !

Rock Paper Scissors

Last night my boyfriend and I were playing "Rock, Paper, Scissors" to decide who had to get up and turn the light off. We picked exactly the same hand shape five times in row before I decided this wasn't going anywhere and gave in! I think the probably of this happening is 1/243 (a 1/3 chance of playing the same shape per game, to the power of 5 games) But, we're not sure: the boyfriend argues that we were subconciously using the same "strategy" and I like to think we've developed some sort of mind reading powers through spending too much time together.

Old friend

I lived in Calgary Alberta and used to drive to Vancouver B.C. once or twice a year to visit my parents On one of these trips a normal stop would be in Kamloops to fill up with fuel, for some reason I decided to skip this stop and try to make it all the way to Vancouver. Well, by the time I got to Merrit B.C. it didn't look like I would make it. I found this old gas station open in town where I had to go. Well here was an old friend I knew from about ten years earlier we had somehow drifted apart. Turns out He had given up on the business life and was pumping gas in a little hic town.

Waterloo

I live just outside Brussels and yesterday whilst driving from Mons to Brussels I put the radio on. I usually always listen to Premiere a French speaking news channel but for some reason instead of pressing pretuned Channel 1, I randomly pressed auto tune and it tuned into a Dutch channel playing abba singing Waterloo. I sang along for a couple of bars then - wait - it can't be, a huge sign on the motorway "Waterloo"; I am driving right past the exit for Waterloo as Abba sing it over and over. I only drive on that road about 8 times a year and always have the French news channel on to practise my French. What are the chances?!

Twins and eggs

I cracked open an egg to make breakfast and it had 2 yolks. Later that day my friend informed me she was adopting twins.

Meeting on a plane

I was due to fly from Los Angeles to UK but the flight was cancelled and I was rerouted on a flight via Chicago, where I'd have to have a stop-over. After take-off, someone asked if I would change seats so they could sit with a partner, and I moved to an aisle seat. I looked across the aisle, and saw a man reading a chapter in a book I knew on a very specialised academic topic that I have published on. There's probably about ten people in the world really interested in this stuff. Emboldened by free alcohol I introduced myself (can't remember how!). He turned out to be someone I'd corresponded with but never met, based in Chicago. It would have been a coincidence anyhow, but seemed all the more amazing since I shouldn't have been on that plane, and should have been in another seat. He was great : we spent hours talking, and he and his wife ended up putting me up overnight.

The Glass Opera T-Shirt Incident

In the late 1990s I worked as a mastering engineer in a low-rent recording and mastering studio somewhere on the European continent. It was the days when access to a CD writer was a special thing. I had the original vinyl recording of Philip Glass' "Einstein On The Beach" Opera and did not want to play it to pieces, so decided to transfer it to CD, while assisting a freelance sound engineer recording a band in the studio next door. I had never met this engineer before, he was a bit older than me and worked at much better gigs than I did. The music he was working on could be described as "chanson". It should be pointed out that a) Philip Glass is not exactly mainstream music and b) he has extremely high standards when it comes to reproducing his work, which makes public performances rare. While fine-tuning the master sound before writing to CD, replaying segments loudly, the freelance engineer poked his head around the door, and gave a start. He then took his shirt off... ...under the shirt he wore the limited edition T-Shirt printed for the premiere of that Opera in that country, a momentous occasion several years earlier.

Friend of a friend of a friend......

At a university party I met a guy who wasnt from my uni but he told me which highschool and what university course he was studying. Also he was moving to Canada in afew weeks or so. The next day I was talking about this guy I met with some friends at univeristy. It so happened that one friend had a friend in the same course as him and knew him. Another friend went to the same highschool as him. The third connection was a week or so later when I was told by a friend that her colleague at work was going to a going away party for aguy who was leaving for Canade. Yes it was him again!
