Hello everyone.(adsbygoogle = window.adsbygoogle || []).push({});

I was just reading Ian Stewart's "Concepts of Modern Mathematics". In the end of the first chapter he writes

A certain theoretical physicist secured himself a mighty reputation on the basis of his deduction, on very general mathematical grounds, of a formula for the radius of the universe [...] It was several years before anybody had enough curiosity to substitute the numbers in it and work out the answer. Ten centimeters."

This seems quite the fluke. Is this actually true? Can you tell me who this "certain theoretical physicist" is/was?

Cheers
