Date coincidence

I gave a Maths talk on the 100 Prisoners Problem and prepared a Powerpoint for the talk. On the opening slide, instead of writing the date, I noticed that the next day would be 14th March, or Pi Day, and so I wrote "The Day Before Pi Day". A few months later in the same year I was asked to give the same talk. This was possibly only the second time I have given this talk formally to a large group. I decided to update the Powerpoint, and, naturally, this included the date.

Finding links with someone. Twice.

I am from a small region in Northern Spain (Asturias). I lived there for most of my life and did my degree and PhD in Biology there (Universidad de Oviedo). In the department I used to work with a guy from Mexico DF. Then I moved to Oxford where I ended up living with a girl from Mexico DF and she is now one of my closest friends.

Unexpected encounter

I live in Brazil with my wife and two kids - a girl and a boy. In june 2010 I travalled with my wife and my daughter (my son had not been born yet) to California. Upon arriving in Los Angeles, we took the shuttle from the rental car company in order to pick up the car we had booked. There was another couple in the shuttle and while we traveled from the terminal to the rental company site, me and my wife were chatting. By the time we arrived at the rental car company office the lady that was in the shuttle approached me and asked if we were from Brazil.

answered phone in phonebox

It was a long time ago before mobiles. I was about 15 walking through town asked a phone rang in Lloyds avenue arches Ipswich and I walked over to answer I knew who it was and they asked for me. It was weeiirrdd. I will never forget it. I exclaimed my incredulity to them telling them I was at a public phone cubicle and I just happened to answer it. The details are hazy now it was 30 years ago but I remember it ringing and answering it and the shock of it. I seem to remember the friend on the phone didn't seem to understand what was happening, the coincidence of it.

Good Cod, I don't believe it

This is not one to read before your lunch. In 1984 I was tucking into a school dinner of battered fish and chips, when I discovered to my horror that the fish contained a coiled up worm or other such parasite. As you might imagine, no more fish for me. About 6 or 7 years later I finally plucked up the courage to try some fish again, the first since the incident. And you’ve guessed it, again I find this particular fish has the same affliction. Somehow I found the whole coincidence so unlikely, that I laughed it off and did return to eating fish fairly regularly.


In 1975 I moved to the town of Hattiesburg MS to complete my degrees in Psychology and Nursing. I had brought my bike with me, and after moving into my apt, I decided to take a bike ride. I was riding along one of the main streets in town when I saw an old cemetery off to my left. I have always loved cemeteries--the quiet and peacefulness--and I liked to look at gravestones and see how old the person was at death and speculate on how he/she might have died. The cemetery appeared deserted, and I rode my bike along a little path for a ways.

Same Birthdays

I graduated high school from the small town of Port Gibson MS in 1966. In our class of 42 students, five of us had the same birthday, Dec. 19. My name is Alice Carroll (maiden name--Sanders). I remember the names of the other 4 classmates with my birthday, but will not relate them here unless needed by the coincidence investigator.

Ex school classmate

While on a cruise to Norway I met an ex classmate who I had'nt seen for 63years.

Weird and geek like coincidence

I lived in Rhodesia in the 1960's and at the age of 14 (ie: 1970), I read a science fiction book that I found fascinating it was called "Earth Abides" by George R Stewart, written in 1949 and was a post-apocalyptic science fiction novel by American writer George R. Stewart. It tells the story of the fall of civilisation from deadly disease and its rebirth.
