SUMMARY:Café Scientifique: The Quantum Universe
DESCRIPTION:With Prof Stephen Wilkins\n\n\n\n\n\n\n\n\n\n\n\n\nDOORS: 7.00pm\n\n\n\nSPEAKER: 7.30pm\n\n\n\n\nIMPORTANT \nPlease ensure you REGISTER prior to attending! \n\n\n\n\nRegister to Attend\n\n\n\n \n\n\n\n\n\nQuantum physics is a fundamental theory that describes the behaviour of nature at and below the scale of atoms. Celebrating 100 years since initial developments\, the United Nations proclaimed 2025 as the International Year of Quantum Science and Technology. As part of these celebrations I will introduce how quantum physics is essential to our understanding of the Cosmos\, focussing on two examples.First\, the process of nuclear fusion is responsible for the majority energy generation in stars; however the temperatures in stellar interiors are too low for this to happen “classically”. However\, the phenomenon of quantum tunnelling enables atomic nuclei to fuse even if they don’t have the required energies.Second\, our Universe is replete with structures in the form of planets\, stars\, galaxies and clusters. These structures are thought to caused by amplification by the process of inflation of minuscule quantum fluctuations present in the very early Universe. \n\n\n\nStephen Wilkins is a Professor of Astronomy and Public Understanding of Science at the University of Sussex. Stephen obtained his Masters in Physics from the University of Durham before receiving his PhD from the University of Cambridge. Stephen then worked as a research fellow at the University of Oxford before joining the faculty at Sussex in 2013.Stephen’s main research focuses on understanding the formation and evolution of galaxies\, particularly the first stages in the distant early Universe. To do this Stephen combines observations from telescopes including Webb and Hubble with supercomputer simulations. Outside his research Stephen is also a keen advocate of public understanding of science. Highlights include his leadership of three exhibits at the prestigious Royal Society Summer Science Exhibition and dozens of talks. \n\n\n\nDoors and bar open 7:00pm\n\n\n\nPlease note that we are entirely dependent on donations from those who attend our events. You can make a donation as you arrive or leave; we are happy to accept cash or card payments. All donations greatly appreciated!
