I was honoured to be part of the Czech delegation, representing @unikarlova.cuni.cz, alongside Professors Jiří Pavlů and Jan Hajič. Our focus was on connecting academic research with industrial innovation, especially in areas where quantum and #AI are rapidly evolving toward real-world impact.

Proč vlastně ti, kteří věří, že volby budou zmanipulované, chtějí jít volit? Vždyť to nemá cenu ne? 🤔

3/5: We've successfully trapped electrons (as stand-ins for positrons) in the electron-ion trap for periods sufficient for experimental purposes. This is a significant step towards our goal! #Research #Innovation

2/5: Our ultimate goal? To produce antimatter by recombining positrons & anti-protons in a compact lab setup. Imagine receiving antiprotons from CERN, transferring them to our trap containing positrons for recombination! #Antimatter #Science

Without the EU, it would have already been implemented in half of the countries without any discussion.

Od počátku svého studia jsem si učinil zásadou, že kdekoliv poznám mínění správnější, ihned upustím od svého méně správného a pokorně a radostně přijmu názor odůvodněný lépe, věda, že to, co víme, je zcela nepatrným zlomkem toho, co nevíme. -- Jan Hus 1410
