I wonder sometimes if our modern structured and red taped upper education model could ever cope with such exceptional individuals at all. I cannot stop thinking they will never get the unbridled space they need to express their ideas and concot together without an heavy amount of supervision and channeling toward 'agreed' topics and behaviours, I think education and the application of the law should be very flexible when exceptional individuals are at stake...
Steinhaus, Ulam and many other mathematicians in the Lviv school were Jewish, and had to flee or go into hiding to survive the German occupation. Interesting that there is no mention of this in the article.

Le Cam called <i>tightness</i>: Roughly, IIRC, for any probability measure P and any a > 0 no matter how small, there exists a sphere S of finite radius so that P(S) > 1 - a. Intuitively the probability mass can't just keep avoiding all spheres; eventually some sphere, if large enough, must cover nearly all the mass. There are some cute technical details.<p>Once in a paper I used Ulam's result to show that a goofy distribution-free statistical hypothesis test was not trivial. And I've seen other applications.<p>The hypothesis test was to improve on our work in artificial intelligence for zero day monitoring for problems in server farms and networks.

There is an intriguing reference here: "...the concept of a spatial x-ray locating device came to [Steinhaus] during a winter stroll spent observing snowflakes falling on his fur coat." Elsewhere, I have found the comment "Steinhaus designed and instrument for localization of strange bodies in the body of a sick person by means of X-rays, based on a simple and elegant geometrical conception (1938) [1]." Does anyone know what this is? A form of tomography, perhaps, or an application of stereology? - which is distinct from tomography, according to this article [2], and is apparently somehow related to his Longimeter, recently discussed here [3].<p>[1] <a href="http://prac.im.pwr.edu.pl/~hugo/HSC/Steinhaus.htm" rel="nofollow">http://prac.im.pwr.edu.pl/~hugo/HSC/Steinhaus.htm</a>
