Dark Matter Day, 31 October 2025
The 2025 Dark Matter Day takes place on 31 October. On and around 31 October 2017, the world celebrated the hunt for the unseen—something that scientists refer to as dark matter. There is a big part of the universe that we do not know much about. We are not sure if dark matter is made up of undiscovered particles, or if it can be explained by tweaking the known laws of physics. Its makeup could teach us much about the history and structure of our universe.

MDPI Webinar | Quantum Mechanics and Open Access 2025, 27 October 2025
Welcome to our webinar series themed “Quantum Mechanics and Open Access”, organized in recognition of the International Year of Quantum Science and Technology (IYQ 2025).
This year marks a historic milestone—the centenary of the birth of quantum mechanics, a field that has transformed our understanding of the universe and continues to drive innovation across physics, chemistry, computing, and beyond. It is both a moment of reflection on a century of extraordinary breakthroughs and an opportunity to envision the next hundred years of discovery.
Our theme highlights not only the profound scientific achievements of the past but also the vital role that open knowledge plays in shaping the future of research. Open access ensures that discoveries are shared, collaborations are strengthened, and progress in quantum science remains a truly global endeavor.
We are delighted to bring together a distinguished group of speakers, researchers, and practitioners who will share their insights on how open access is transforming the way we communicate, collaborate, and innovate in quantum science.
Thank you for joining us on this exciting journey of science, openness, and collaboration. We look forward to engaging in discussions and to collectively imagining the quantum future together.
