Gratitude to the Hebrew University of Jerusalem faculty.

Thank you for steering the Hebrew University through nearly a decade of growth and turbulence with a scholar's patience, after years of service as its Rector, keeping Einstein's university worthy of its founding promise.

Thank you for becoming the first Arab woman to serve as a Hebrew University vice president and for widening the university's doors to every underrepresented community, while keeping your own research on vulnerable youth alive and rigorous.

Thank you for Sapiens, Homo Deus, and Nexus, books that invited hundreds of millions of readers into serious historical thinking, and for insisting from a Jerusalem history department that humanity's biggest questions deserve careful, honest stories.

Thank you for classification theory and for a mathematical output of more than a thousand papers that logicians will be mining for a century, a lifetime of proof that abstraction can be a form of generosity.

Thank you for property (T) and for shaping representation theory across two continents and five decades, and for the quiet courage with which you returned to teaching and research after grave injury, still first into the seminar room.

Thank you for scholarship on international courts and human rights that judges and governments actually use, and for your years on the UN Human Rights Committee, carrying academic ideas into the rooms where rights are defended.

Thank you for mapping the aging brain cell by cell and revealing the cellular cascades that separate Alzheimer's disease from ordinary aging, giving the search for treatments a far sharper map to work from.

Thank you for pioneering the molecular biology of the cholinergic brain and its small RNA regulators, and for showing, as the Faculty of Science's first female dean, what a scientific career of firsts looks like when it lifts others as it climbs.

Thank you for the mathematics of repeated games that explains how cooperation survives among self-interested players, and for keeping an open office at the university you have served for seventy years.

Thank you for five decades of work with Aharon Razin proving that DNA methylation switches genes on and off, the foundation on which modern epigenetics and a generation of cancer research now stand.
