Tusnady’s Lemma, 24 Years Later

– The optimal coupling between a variable with the Bin(n,1/2) distribution and a normal random variable lies at the heart of the proof of the KMT Theorem for the empirical distribution function. Tusnády’s Lemma (published in 1977 in his dissertation and in Hungarian) provides an inequality with explicit absolute constants which says that for this coupling, the distance between the random variab...

Indoor radon entry: 30 years later

The paper discusses the results of 30 years of radon indoor entry research. While some progress has been made, many discrepancies between current theories and experimental data still remain. Misconceptions of radon transport mechanisms in homes are analyzed. The role of US Environmental Protection Agency in radon indoor entry research is examined and the agency's policies are criticize...

50 Years of Bailey’s Lemma

Half a century ago, The Proceedings of the London Mathematical Society published W. N. Bailey’s influential paper Identities of the Rogers–Ramanujan type [16]. The main result therein, which was inspired by Rogers’ second proof of the Rogers– Ramanujan identities [49] (and also [48, 28, 15]), is what is now known as Bailey’s lemma. To celebrate the occasion of the lemma’s fiftieth birthday we p...
