Tardiness solves statistics theorems

Posted to Statistics  |  Nathan Yau

Yeah, you read that right. Tardiness makes the world go ’round:

One day in 1939, Berkeley doctoral candidate George Dantzig arrived late for a statistics class taught by Jerzy Neyman. He copied down the two problems on the blackboard and turned them in a few days later, apologizing for the delay — he’d found them unusually difficult. Distracted, Neyman told him to leave his homework on the desk.

On a Sunday morning six weeks later, Neyman banged on Dantzig’s door. The problems that Dantzig had assumed were homework were actually unproved statistical theorems that Neyman had been discussing with the class — and Dantzig had proved both of them. Both were eventually published, with Dantzig as coauthor.

Other benefits include more hours of sleep, exercise while power-walking to your destination, and all-around warm, fuzzy feelings knowing that you live by nobody’s schedule. You might also supposedly inspire films like Good Will Hunting.

Who knew?

  • Nice… unwittingly solving unsolved problems sounds like a pretty good outcome.

    Nice. What I don’t get is why Dantzig was only co-author, surely if he solved the unproved statistical theorems …..?

    Tardiness is often caused by extreme (and unrealistic) optimism. That’s my excuse.

    • That’s grad school for you :)

    • The co-author situation happens a lot in grad school, but it does make sense. The prof probably spent a *lot* of time verifying that they were indeed proofs. Having a better-known name on it also gets it a bit more legitimacy, as otherwise you get shoved into the pile of potential-crackpots.

  • Great story. Maybe its worth mentioning that Dantzig is the father of Operations Research. He invented the Simplex Method (Linear Programming).

  • It all goes to show that Statistics and Operations Research do work together!! Another point about Dantzig is that he was devoted to applying mathematics to environmental issues later in life. It is a testament to his genius that he invented a robust, easy method to solve linear programs which is still in wide usage.

  • Maybe that’s why classes at Berkeley run on “berkeley time” — they all start 10 minutes late.

I wanted to see how daily patterns emerge at the individual level and how a person’s entire day plays out. So I simulated 1,000 of them.
