Adriana's lecture on "Physik am Samstag"

On the 8th of October Adriana was giving a lecture in the frame of the lecture series "Physik am Samstag". There, she was talking about the nuclear clock candiate Th229. The summary of the lecture is: "Punctuality is highly valued in our society. But what makes our clocks so accurate and which clock generators are used to measure time? Since 1967, the second has been defined with the help of an atomic transition. The tiny atoms allow us to measure time very precisely and synchronize signals perfectly everywhere on Earth and also in space.  Even better accuracy could be achieved using the transition frequency of an atomic nucleus as a clock generator. Because atomic nuclei are spatially much smaller than the atomic electron shell, external disturbances affect their transition frequencies much less.  A suitable candidate for a "nuclear clock" is the isotope 229-thorium, named after the Scandinavian god Thor.  A clockwork based on it would not only be useful for measuring time, but could also answer fundamental questions, such as whether natural constants are truly constant. The lecture will give an insight into how time is measured and what consequences this has for both our society and our fundamental understanding of nature".
