On 21 November 2025 (Friday), from 10:00 to 15:30, the Scientific Complex 2 of the Bulgarian Academy of Sciences (72 “Tsarigradsko shose” Blvd., Sofia) will host, for the first time, a joint Open Day dedicated to the contemporary achievements of Bulgarian science in the fields of physics, renewable energy, electronics, and astronomy.
The event is organized by four scientific units of BAS located within the complex:
- Central Laboratory of Solar Energy and New Energy Sources – BAS
- Institute of Solid State Physics – BAS
- Institute of Electronics – BAS
- Institute of Astronomy with National Astronomical Observatory – BAS
The Open Day, themed “Light, Energy and Technologies of the Future: from Celestial Mechanics to the Dynamics of Atoms”, provides visitors with the opportunity to explore up close the diverse scientific fields developed within the complex — from photonics and nanotechnologies, through new materials and energy-efficient systems, to the observation of the Universe.
The program includes:
- Lectures and demonstrations by leading scientists and young researchers;
- Visits to laboratories with the opportunity to observe real experiments and equipment;
- Astronomical observations of the Sun (weather permitting);
- Screenings of documentary films;
- Presentation of innovative materials, laser technologies, and photovoltaic systems;
- Demonstrations of high-tech equipment.
Highlights from the program of the Institute of Solid State Physics – BAS:
- How does physics transform the computers of the future?
- How have nanotechnologies evolved from antiquity to the present day?
- How are physics and laser technologies used to detect and study microplastics?
- How does science address one of the most serious environmental challenges of our time?
- Lasers and hidden filters: how does light choose its path?
- Superconductivity — what are the modern challenges and perspectives?
- What is the difference between femtosecond and picosecond laser systems, and what are their applications?
- What is a magneto-optical trap for rubidium atoms?
- How are filters, mirrors, and anti-reflection coatings for scientific instruments and lasers created?
- How does science develop systems for controlled and precise drug delivery in the human body?
- What analytical techniques do scientists use for quality control and toxicological analysis of alcoholic beverages?
The program is intended for high-school students, university students, PhD candidates, educators, as well as the general public with an interest in modern science and technology.
