by Elvis Pillinen Since the invention of the first laser in the 1960s, researchers have discovered that by mode-locking, optical pulses can be made much shorter, even down to mere femtoseconds. In human perspective, pulse created by a flashlight (millisecond, 10-3 s) is 300 km long, enough to stretch from […]

by Otto Veltheim, University of Helsinki Imagine having an unknown system, a “black box”, which outputs identical copies of an unknown quantum state. Suppose our task is to identify the state. There are multiple attributes, i.e. observables describing it, and measuring just one of them makes the state collapse to […]
The International Union of Pure and Applied Physics (IUPAP) is celebrating 100 years of active service to the international physics community. The Finnish Physical Society (FPS) is an official member of IUPAP representing the interests of the Finnish physics community. Joining the centennial celebrations we are planning a scientific photography […]
Founded in 1947, the Finnish Physical Society (FPS) is celebrating this year its 75th anniversary with an in-person event that will take place on the 2nd of September 2022 at Porthania building of the city center campus of the University of Helsinki. The event will consist of a small series […]
The first issue of Arkhimedes journal for 2022 is now published online! It focuses on the investments in quantum technology and in particular the development of the Finnish quantum computer. One of the articles is dedicated to InstituteQ, the Finnish national quantum institute and its placement in the quantum technology […]
One of the finalists for the FPS MSc Thesis Prize 2021 was Perttu Hilla, who completed his Masters degree at the University of Oulu. To learn more about Perttu’s MSc thesis work that brought him to the final round of the FPS MSc Thesis Prize 2021 you can watch the […]
Jonas Suni, University of Helsinki Space physics concerns the study of the near-Earth plasma environment, which stretches from around 60 kilometres to hundreds of thousands of kilometres above the Earth’s surface. This vast volume of space can however be divided into a few different regions of interest. Closest to the […]
Katja Tolkkinen, University of Oulu Osteoarthritis is a degenerative disease of the articular cartilage, and it is one of the most common reasons for disability. Articular cartilage is an essential part of the human body because it allows smooth and painless movement of the joint. It is the highly specialized, […]
Kaapo Seppänen, University of Helsinki Quantitatively understanding the thermodynamic properties of dense strongly interacting matter has recently become a hot topic in nuclear and particle physics. The leading factors behind this are major observational advances in neutron star physics, including the famous observation of gravitational waves from neutron star mergers […]
Kirjoitus on osa blogisarjaa, jonka aiemmat osat on julkaistu täällä. A Night with the Space Nobelists -sarjan päätösjakso toteutettiin kolmesta ensimmäisestä jaksosta poiketen. Viimeisessä jaksossa tähtitieteilijät Maarit Käpylä ja Peter Johansson keskustelivat paikan päällä studiossa Nobelin palkinnon merkityksestä ja huippututkimuksen edellytyksistä. Käpylä toimii professorina Aalto-yliopistossa ja tutkimusryhmän johtajana saksalaisessa Max […]
