Welcome
to CavMag 34
Hello from the Student Editors
This special issue of CavMag represents something new, as we, a group of postgraduate students, step into the editorial role to shape this edition. For us, this has been a chance to see the Cavendish from a fresh angle: not only as a place of research, but as a living community of ideas, people, and shared curiosity. We hope this issue reflects the vibrancy, imagination, and sense of discovery that make the Department of Physics what it is today.
Features
Shining light
Cavendish astronomers are turning their ground-based expertise towards a mission to the far side of the Moon. The goal: understanding the cosmos from before the stars were born.
Bouncing droplets
Microscopic water droplets rebound off surfaces only in a narrow “just-right” speed range, a finding which has real-world implications from inkjet printers and crop sprays to the behaviour of virus-carrying aerosols.
Solar breakthrough
Cavendish physicists in collaboration with Yusuf Hamied Department of Chemistry discovered a new mechanism using a single organic material for light harvesting, which could redefine the future of solar energy, and lead to lighter, cheaper, and simpler solar panels.
Interview: Nicola Marzari
The tenth Cavendish professor, Nicola Marzari, talks to CavMag about bridge computation, curiosity, and the human side of physics.
Twists in the flow
Cambridge-led physicists show that voltage-driven torque spins DNA into supercoils (plectonemes), not just knots – reshaping how we interpret “tangled” nanopore signals.
A tactile history of science
Physics is communicated in many forms, but perhaps the most enduring is the printed book. For centuries, physicists have filled their shelves with volumes both weird and wonderful, and the bindings, annotations and doodles within those volumes record the lives of the people who leafed through them.
Your Cavendish memories
Nigel Allsopp (Radio Astronomy group 1975-78) recalls working at the Half-Mile Radio Telescope at Lord's Bridge.
