Иногда бывает, что человек написал одну статью и слился из науки, но статья оказывается важной, в честь него названа формула или закон. А бывает, оказывается, и что человек не имеет PhD, пишет статьи с домашнего адреса, и их публикуют в Nature.

Вот тут коллега в работе об энтропии Вороного (использующейся для характеризации двумерной самоорганизации на поверхностях или на картинках) помянул "Aboav's law", связанный с соотношением между средним числом граней ячейки Вороного с числом соседей у ячейки (большие ячейки соседствуют с маленькими, и наоборот).

Поскольку это знаменитая амстердамско-сефардская фамилия (также любимая мною с-га Абугава в Цфате), я заинтересовался: кто такой Давид Абоав? Речь вот об этой его статье
D. A. Aboav, The arrangement of grains in a polycrystal, 29Metallography 3383-390 (1970).

Вот что я прочитал про другую статью Абуава (связанную со структурой пен):

"After obtaining results that were in accord with expectations based on dimensional analysis, Smith left his 2D foam aside and let others take the analysis further. One of the first to do so was David Aboav, a former Assistant to E N da C Andrade in London.

Working on his own and publishing from a private address, Aboav presented an analysis of data taken from photographs sent to him by Smith [3] D.A. Aboav, Metallography 13 (1980) p.43. According to this there was a serious anomaly: the results did not conform to the obvious scaling theory that Smith had stated or implied.

Aboav’s surprising contribution exemplifies various home truths about research.

Lacking the rigorous training of a doctorate, he was not sufficiently self-critical.
Much later it emerged in his correspondence with myself that he had deliberately discarded photographs (from the set given to him by Smith) that did not conform to the trends he observed earlier in the time series. So he was analyzing only short-time transient rather than the asymptotic behaviour at longer times, which was Smith’s objective.

Understanding Aboav’s paradoxes was the stimulus to the first realistic attempt to simulate 2D foam structure and growth (Figure 1). With a few suggestions from me, Paul Kermode wrote a remarkably successful simulation program. His results look good even to today’s eye, but the computational limitations of that time prevented us from reaching firm conclusions about asymptotic coarsening"

А вот забавное письмо этого Абоава в редакцию Nature: https://www.nature.com/articles/333009c0
