该项目旨在为安徒生博物馆、花园和Tinderbox文化中心建造一座新建筑。新建筑位于欧登塞—安徒生出生的城市的市中心。项目用地位于拥有中世纪小型传统木屋的住宅区和欧登塞新开发的城区之间。这里要讲述的故事不仅以书面形式存在，而且是通过博物馆和花园的物理空间来体验和感知的。安徒生的作品传达了深刻的信息，反映了作者的人生历程。安徒生的作品展现了围绕我们的各种双重对立：真实与想象，自然与人造，人与动物，光明与黑暗……事物的对立面共存，它们不是黑白的。我们的建筑设计就是要以建筑和景观的方式体现他作品的精髓。

These are expanded notes from lectures on the geometry of spherical varieties given in Sanya. We review some aspects of the geometry of spherical varieties. We first describe the structure of B-orbits. Using the local structure theorems, we describe the Picard group and the group of Weyl divisors and give some necessary conditions for smoothness. We later on consider B-stable curves and describe in details the structure of the Chow group of curves as well as the pairing between curves and divisors. Building on these results we give an explicit B-stable canonical divisor on any spherical variety.

The answer to the question How far can one send a photon？ depends heavily on what one means by a photon and on what one intends to do with that photon. For direct quantum communication, the limit is approximately 500 km. For terrestrial quantum communication, near-future technologies based on quantum teleportation and quantum memories will soon enable quantum repeaters that will turn the development of a world-wide-quantum-web （WWQW） into a highly non-trivial engineering problem. For Device-Independent Quantum Information Processing, near-future qubit amplifiers （i.e., probabilistic heralded amplification of the probability amplitude of the presence of photonic qubits） will soon allow demonstrations over a few tens of kilometers.

The growth of nanocrystal superlattices of 5 nm single domain Au nanocrystals at an air-toluene interface induces formation of well-defined thin films （300--400 nm） with large coherence lengths. High-resolution electron microscopy showed that polyhedral holes （negative supracrystal） were formed on the nanocrystal superlattice surface. Formation of negative supracrystals is attributed to inclusion in the superlattice of organic molecules （dodecanethiol）, which are present in concentrated zones at the air-toluene interface. The coexistence of two supracrystalline structures （bcc/fcc） is attributed to diffusion of dodecanethiol molecules resulting in a Bain deformation of the nanocrystal array.
