Metrology podcasts

Benjamin Thompson and Elizabeth Gibney discuss an experiment trapping a single positron and how precise measurements could probe differences between matter and antimatter. The episode then turns to JAXA’s mission to Phobos, including the challenge of operating a wheeled rover under extremely low gravity. These conversations connect laboratory tests of fundamental physics with the engineering and scientific aims of planetary exploration.

This Nature Podcast episode discusses telephone tutoring during school shutdowns and what changing world-map projections could mean for atlases. Research highlights cover synchronized optical clocks and greenhouse-gas emissions from pigs. The publisher provides the episode audio on Acast.

Markus Suta of Heinrich Heine University Düsseldorf speaks with Tom Götze-Ebert about inorganic photoactive materials and phosphors spanning infrared to ultraviolet wavelengths. The episode examines material choices for lighting, approaches to improving environmental performance and the use of luminescence to measure temperature.

Samantha Burgess explains how researchers estimate the Earth’s temperature and monitor a changing climate. The episode examines the observations and international scientific collaboration behind global temperature records, and the work involved in assessing the planet’s changing conditions rather than treating a single local measurement as a global answer.

Tom Herring introduces high-precision geodetic measurements using satellite navigation, very-long-baseline interferometry and radar interferometry. He explains how improved accuracy and cheaper receivers expand studies of plate motion, earthquake-related deformation and Earth rotation, with further applications in infrastructure and agriculture.
