Now when I see 2012 I realise that the hour is about to change. I'm learning! 😉

Chen-Ning Yang (often known in the US as “Frank”) passed away in Beijing yesterday at the age of 103.
He was the last of the great figures of 1950s high-energy particle physics still with us.
His name is associated with two of the central ideas of what was to become the Standard Model.
In 1953, together with Robert Mills, he wrote down…

Auch die seit dem Jahr 1922 jedes Jahr im September veranstaltete Bohnenmesse trägt den Namen des berühmten Gärtners.

Misschien moeten we even een aantal jaartjes alleen vrouwen laten stemmen.
We hebben nog wat goed te maken voor de periode 1917-1922.

Optimal frames for Phase Retrieval from Edge Vectors of Optimal Polygons
This paper aims to characterize the optimal frame for phase retrieval, defined as the frame whose condition number for phase retrieval attains its minimal value. In the context of the two-dimensional real case, we reveal the connection between optimal frames for phase retrieval and the perimeter-maximizing isodiametric problem, originally proposed by Reinhardt in 1922. Our work establishes that every optimal solution to the perimeter-maximizing isodiametric problem inherently leads to an optima…
