Jeff Goldblum should make a film about this legendary mathematician

Paul Erd艖s was one of the most prolific mathematicians to ever live, known for showing up at the door of others in the field and declaring they should host and feed him while they do maths together. His radical life should be immortalised by Hollywood in a comedy biopic, says columnist Jacob Aron

I come to you with something a little different for my latest maths column 鈥 a plea to Hollywood to make a comedy biopic about one of the greatest mathematicians of all time, Paul Erd艖s.

Why is Erd艖s (pronounced 鈥渁ir-dish鈥) deserving of such acclaim? With almost 1500 papers to his name, he is probably the most prolific mathematician that ever lived, and possibly that will ever live. Unsurprisingly, with that many papers, he is known for his work across many areas of maths, from probability to number theory to graph theory. Erd艖s achieved this output through a unique way of working: radical, and some might even say aggressive, collaboration.

Erd艖s was born in Hungary in 1913 and died 鈥 at a maths conference of all places 鈥 in 1996, but for much of his life he had no fixed abode. With the rise of Nazism in Europe, he left Hungary in 1938 for the US, but in the 1950s and 60s was denied entry to the US for his links to communist sympathisers. Instead, he travelled from place to place with a suitcase, turning up at a mathematician鈥檚 door and declaring 鈥淢y brain is open鈥. The unspoken deal Erd艖s offered was that his host would house, feed and generally care for him for a few days, and in return they would receive the chance to collaborate on some world-class mathematics.

Much of the lore around Erd艖s was laid down in , a biography of Erd艖s by Paul Hoffman that was published shortly after the mathematician鈥檚 death. I first read it as a teenager and utterly adored it, but I feel that its potential to reach a much wider audience has been criminally underappreciated, which is why this column marks the start of my official campaign to have it made into a film 鈥 starring none other than Jeff Goldblum.

Why Goldblum? Superficially, he and Erd艖s share a remarkable resemblance, and Goldblum of course already has one iconic mathematician role under his belt in the form of Ian Malcom from the Jurassic Park franchise. But I think it goes deeper than that 鈥 Goldblum鈥檚 brand of weird eccentricity is a perfect match for the way Erd艖s lived his life.

Take his approach to religion. Erd艖s was a self-declared atheist, and yet frequently referred to God, who he named the 鈥淪upreme Fascist鈥, or 鈥淪F鈥. He would say that the SF owned a book, or rather 鈥渢he Book鈥, which contained all possible mathematical theorems, proved in the most elegant way. His life鈥檚 mission was to recreate the proofs from this mighty tome, stealing them out from under the SF.

Erd艖s also excelled at pithy turns of phrase. He referred to children as 鈥渆psilons鈥, for the Greek letter often used in mathematics to denote a small quantity. If an acquaintance quit mathematics, he said that they had 鈥渄ied鈥 鈥 those who had actually died had merely 鈥渓eft鈥, in his mind. Another favourite was 鈥淎 mathematician is a device for turning coffee into theorems,鈥 although he nicked that one from his fellow Hungarian mathematician Alfr茅d R茅nyi. I can already imagine this dialogue tumbling out of Goldblum鈥檚 mouth.

Another fun part of the Erd艖s story already has a Hollywood connection. Because he had so many collaborators, mathematicians like to show off their 鈥淓rd艖s number鈥 鈥 the number of hops it takes to get back to him when you trace networks of paper authorship. In other words, people who worked directly with Erd艖s have an Erd艖s number of 1, while people who worked with these close associates are a 2, and so on. My Erd艖s number is 3, if I cheat a little bit 鈥 I haven鈥檛 written any mathematical papers, but I have written a number of articles in which I鈥檝e interviewed and quoted Terence Tao at the University of California, Los Angeles, who has an . That sort of counts, right?

Anyway, this is remarkably similar to a game called Six Degrees of Kevin Bacon, which attempts to map the connections between actors, centring on the star of Footloose and dozens of other movies. If you鈥檝e acted in a film with Bacon, you have a Bacon number of 1, and so on. Goldblum, incidentally, has a because both actors starred in a cycling mockumentary called Tour de Pharmacy, though I can鈥檛 say I had heard of it before starting this campaign.

A few very special people bridge these two worlds, holding a coveted Erd艖s鈥揃acon number, which is simply the sum of your Erd艖s and Bacon numbers 鈥 you must have both to qualify. Generally, these include mathematicians who have made cameos in films or actors that authored a paper while at university. The current record for the lowest Erd艖s鈥揃acon number is 3, by one of Erd艖s鈥檚 collaborators, the mathematician Daniel Kleitman, who appeared as an extra in Good Will Hunting 鈥 the cast of which has many close connections to Bacon. But if Goldblum can find a mathematician with an Erd艖s number of 1 to write a paper with him, he could match that record. There isn鈥檛 much time left though, as anyone with an Erd艖s number of 1 that is still alive is also getting on a bit 鈥 Hungarian mathematician Lajos P贸sa, who worked with Erd艖s as a teenager, is the youngest I could find at the age of 78.

So far, I鈥檝e painted a fairly fun picture of Erd艖s, but it is also worth pointing out his flaws. Although not described as such in The Man Who Loved Only Numbers, Erd艖s was clearly sexist, referring to women and men as 鈥渂osses鈥 and 鈥渟laves鈥, while to be married was to be 鈥渃aptured鈥 鈥 though it should be said he was happy to collaborate with female mathematicians. His habit of turning up at people鈥檚 homes unannounced and uninvited was not exactly in keeping with social norms, and I鈥檓 sure there must have been times when a mathematician (or their family) opened their door to the scruffy Erd艖s and thought 鈥淎rgh, not this guy again!鈥.

Another knock against my dream of an Erd艖s biopic is that it leans fully into the 鈥渁bsent-minded professor鈥 stereotype of mathematicians, and do we really need another story that reinforces such stereotypes, potentially putting people off from enjoying mathematics? I鈥檓 sympathetic to that argument, but I鈥檒l dismiss it for two reasons.

The first is that all the major mathematical biopics to date have been serious affairs 鈥 think A Beautiful Mind, about John Nash, or The Man Who Knew Infinity, which tells the story of Srinivasa Ramanujan (as it happens, it was in my review of the latter where I first floated the idea of Goldblum as Erd艖s). A comedy maths biopic just hasn鈥檛 been tried before.

The second is that Erd艖s has left a legacy of unsolved problems of varying degrees, some of which even come with a cash reward for solving. These problems surely deserve a wider airing amongst puzzle-minded folk, and indeed there is currently a fascinating renaissance underway in which amateurs are using AI-assisted tools to make real progress in them. Erd艖s would almost certainly approve of a film that helped spread his gospel further, encouraging people to pick up a pencil (or chatbot) and continue his eternal battle against the Supreme Fascist in an attempt to decipher the Book. Jeff, if you (or your agent!) are reading this, give me a call 鈥 I鈥檓 ready and willing to help get this made.
