Xin chào mọi người,
Most EVA Air flights originate out of Taiwan Taoyuan International Airport, its main hub near Taipei, Taiwan. At Taiwan Taoyuan International Airport, EVA Air's flight operations are concentrated in Terminal 2. Additionally, EVA Air and its domestic subsidiary UNI Air operate numerous flights out of Kaohsiung International Airport. A focus city for EVA Air outside Taiwan is Bangkok's Suvarnabhumi Airport, with westerly connections to all its European destinations except for Paris, which is flown non-stop.

Et non, pas de lapin ni d’oeuf de pâques pour ce dimanche. J’ai passé pas mal de temps en famille et aussi pas mal de temps à dessiner. Alors la photo date du soir, un jeu de lumière la nuit sur la façade de ma maison.

Hi @Dhan Hurley this sounds really interesting. As you mentioned it provides a 5 base logic compared to our current 2 base logic. I don't know much about that topic, but I read an article about a Chinese team who built a quantic computer that outperforms all we know currently. If I remember well it was able to provide 3 base logic. I assume even on a 2 base logic, a quantic technology would be faster right? What would be the benefit of an analogic solution like this?

Inverse-designed metastructures that solve equations....Signal processing of light waves can be used to represent certain mathematical functions and to perform computational tasks on signals or images in an analog fashion. Such processing typically requires complex systems of bulk optical elements such as lenses, filters, and mirrors. Mohammadi Estakhri et al. demonstrate that specially designed nanophotonic structures can take input waveforms encoded as complex mathematical functions, manipulate them, and provide an output that is the integral of the functions. The results, demonstrated for microwaves, provide a route to develop chip-based analog optical computers and computing elements.
Metastructures hold the potential to bring a new twist to the field of spatial-domain optical analog computing: migrating from free-space and bulky systems into conceptually wavelength-sized elements. We introduce a metamaterial platform capable of

Self-stabilizing photonic levitation and propulsion of nanostructured macroscopic objects....
Light is a powerful tool to manipulate matter, but existing approaches often necessitate focused, high-intensity light that limits the manipulated object’s shape, material and size. Here, we report that self-stabilizing optical manipulation of macroscopic—millimetre-, centimetre- and even metre-scale—objects could be achieved by controlling the anisotropy of light scattering along the object’s surface. In a scalable design that features silicon resonators on silica substrate, we identify nanophotonic structures that can self-stabilize when rotated and/or translated relative to the optical axis. Nanoscale control of scattering across a large area creates restoring behaviour by engineering the scattered phase, without needing to focus incident light or excessively constrain the shape, size or material co... show more

Physicists predict a way to squeeze light from the vacuum of empty space | Science | AAAS



Physicists have long known that energetic charged particles can radiate light when they zip through a transparent medium such as water or a gas. In the medium, light travels slower than it does in empty space, allowing a particle such as an electron or proton to potentially fly faster than light. When that happens, the particle generates an electromagnetic shockwave, just as a supersonic jet creates a shockwav
