Cambridge Coincidences Collection

Well I Never!

Professor David Spiegelhalter of Cambridge University wants to know about your coincidences!

My elementary school(grade 4-6) best friend and junior high best friend became best friends in high school and college!

My definition of "best friend" is a friend you hang out with the most during a period of time, not necessarily always being your closest friend throughout. I grew up in WuHan, one of the most populated cities in China. I went to two different schools from grade 4-9. Grade 4-6 I was in Huaao and grade 7-9 I was in Huayi. Those were boarding schools, they weren't close to each other and students were from all over the city. Wherever I was, there was always one friend that I spent the most time with.

lost phone coincidence

Hello, This happened in 9th of August, 2014. I studied all night for my exam, then left home early to catch my exam. I was waiting in the bus stop for my bus, when this beggar came and asked for money saying he needed food. I usually either say no to these kinds of things or just neglect them. But that morning I felt like helping to that dude, so I went and bought a bagel for him, he thanked me, while eating the bagel. He sat next to me and we had a little chat about his daily problems, then my bus arrived and I left for my school. I took the exam.

Small world San Jose

I was traveling for business to Monterey, CA from my office near Las Cruces, NM with flight in/out of San Jose, CA. While refueling the rental auto at a gas station very close to San Jose Airport, I looked on the other side of the pump and there was one of my co-workers from NM -- also refueling his rental auto. However, he was not on business, he was about half way through his two-week vacation driving through various wine-making regions of CA. We just happened to pick the same pump, same gas station, same town and same time.

Birthday coincidence

In light of the familiar birthday problem I often share a wonderful coincidence of birthdays in my family. My sisters were born on the same day of the year seven years apart. My wife also has siblings, not twins, who share a birthday--the same as my sisters'.


Today I was thinking of making website that would collect people's coincidences.

simultaneous events

I was reading something and someone else in the room say the same word exactly when i read it in my mind. On another day I was talking to someone and my brother was reading something, he said "what did you say?" and he showed me a word I said that was in something he was reading. This was a long time ago and I don't remember what the words were but they were not the same word. Two words on two different occasions. Two people phone each other at the same time.. that happened to me too.

what are the chances?

Fringe Festival season in Edinburgh. My friend A emails me to say a mutual friend, R, has had his house in central Edinburgh struck by lightning. His email title is "What are the chances?" So after sending a sympathetic email to R, I ponder on the improbability of lightning striking a medium height building in the middle of a city. I sleep a peaceful night and wake to iplayer on my iphone. Tune to Brian Cox's "Infinite Monkey Cage" but having already heard the latest episode I dozily click at random on an early episode.


Hi, I have always had feelings or instincts that tell me what is about to happen. I do not always feel this every single time, however when i do my feeling is always right. For example, i am a rower, and sometimes before a race, i will get this feeling that im going to win or lose this particular race. Or ill get a feeling that ill get an A in an exam. These instincts will always be right. I understand these could just be coincidences, but every single time they are right; this seems strange to me. Thanks for reading, Georgia

In reference to "Date of Birth"

The Odds to meet one with the same date of birth (day, month, year ) I would figure appr. 1:30000, but it differs according to which month one was born . In the Continental sphere significantly more people are born in July, Aug., Sept. than in the winter months...
